What bogan is bashing together

[bogan]

So I have lots of small projects on the go, most are done with the 'why the fuck not' attitude, so, in the interests of encouraging youse fullas to do similar stuff, I'll just post up some of the things I'm up to.

First up, heres 4 instructables we put together recently:

http://www.instructables.com/id/Gyrocompass-Dead-Reckonator/
http://www.instructables.com/id/LCD-Screen-Gantry/
http://www.instructables.com/id/Helpful-Bathroom-Octopus/
http://www.instructables.com/id/Fnork-20/

And my big project at the moment is a garage CNC, 675x458x160 envelope; currently it'll do wood ok but noisy, so I'm building a new spindle to remove the mm or two play in the router I'm currently using, attached the pic of the new spindle. Can't find fuck all of the mill though, will get some later. It also is pretty handy with a pen!

PS, this is in modifying motorbikes cos a lot of this stuff is getting the tooling to do so, and will be plenty of small jobs put up here too; also, it's pretty much the same skill set and interest.

[nathanwhite]

:killingme at that octopus. Be awesome having that

I do like that screen gantry though, thats very cool :niceone:

[carburator]

be interested to see pictures of your mill, you need some decent ridigdy for doing
alloy and steel, though the noise of mine on alloy is as bad as the router going hard!

I would'nt mind building a bigger unit as I need 800 travel in one axis..

[bogan]

Here's the mill, it's not the most rigid (flying gantrys generally aren't) but I'm hopeful it'll do alright on aluminium. What's your setup like carburator?

[bogan]

Also cake :drool:, good engineers are often decent cooks too, same sort of processes.

[bogan]

And working on a vibratory finisher, to debur and polish parts the mill spits out. Currently trying to track down a source for media, it sounds like plastic cones for deburring, and walnut shell + rouge for polishing. Will see how it turns out anyway. Top table has a motor with eccentric weight, and that is all isolated from the base through a fork spring; fairly common design, so I'm hopefully it'll work once I get the media in there.

[nathanwhite]

The cake is a lie

Loving the Fnork 2.0 but I am questioning whether you are living in NZ. That piece of meat you're cutting (and eating :sick:) Looks f'ing revolting. Shame! (but neat ideas :-) )

hopefully ive attached the right piccies, mine is a direct copy of jasons ( ZEALCNC ) desktop
im currently looking to build a gantry hybrid, fixed brigde but the table moves.. as i only
need limited area. but lenght! at least 800mm

most of my machine work is A4 size and third axis

polishing media, at anzes we used to use a ceramic trilob wet in a rumbler ( made alloy parts look smick )
ive used walnut and corn husch before for fine polishing, the thing you do need is a circular chamber else
the parts end up in the corner and does'nt work that well..

[bogan]

looks pretty nice, 4th axis is on the to do list for mine too. Hybrid sounds like it would be the way to go. I think minimizing the working height is also a good way to get rigidity. My next one might just be a plate mill, only run about 50mm depth, maybe a few flat bar feeders and autoclamps if I can get work for it... This one was designed to be as multipurpose as the budget/design allowed, learn heaps from it, and then make more specialised ones for production parts; will be putting an MDF CF tank mold through at some point though, that should be fun :D
You had much jobs through yours?

Yeh I've heard tyres from ride on lawn mowers make good chambers, will use a few old bowls/pots/pans while I figure out what a good size/shape is, round bottom bowls ten to turn the parts over more I think.

[bogan]

Wouldn't be a proper sunday without a bit of shed time!

Spindle stuff in main bit, spindle spanners on right, and rearsets/chain roller/kickstand in back corner.

[The Lone Rider]

You fellows and your wang fang doodle mills and cnc do dads.

I smash out and cut everything by hand; old school rule.

Still, some of the more useful things I'd like to put on a bike would have been nice (and quicker I guess?) if I had that kind of kit and the space for it.

Frankly I think we need community workshops for people with bikes.

[DrunkenMistake]

All I read was CNC over and over...


Your going to make some cnc bling for my bike?
No dont its not needed..
oh if you insist but..
Ok ok sure if you really want to..

Well if your going to be like that you can get fucked..


OK FINE MAKE IT...

Yeh, would take about 10x as long to hand make fancy machined bike parts though, most people just get a bit more blocky when its hand made.

Well hopefully I'll be able to open my workshop up a bit for other modders, might need a bigger one though...

Yeh same here, but them rearsets would be bastards to debur and clean up without some sort of media blasting, and apparently you can get a near mirror finish with a vibrapolisher.

[ducatilover]

My garage is bigger than yours :bleh:

Ill take some rear sets,
An exhaust hanger of sorts,
Maybe a triple clamp, Will get back to you with more ideas...


And if your bored you can make me a twin pipe up-sweep system for my hyo..:shifty:



Fuck im smooth..

Might have to put in a freight entrance to cope with the cookie volume then :bleh:

Got two hardware orders turn up today, so put the spindle together a bit more, might even get it spooling up tomorrow with a bit of luck...

[The Lone Rider]

My garage is bigger than yours :bleh:

You'd be jealous of how small mine is.

More so now as I got to store furniture in it at the moment.


For those who CNC... in theory could you bake up a giant pan of cookie dough, chuck the cooked block in a CNC and make yourself an awesome looking cookie?

Well mine is going to have a top down oil feed, so may not be advised... otherwise, yeh it would probly work, probly a pretty rough finish though.
Massey were looking at making a cake printer, which baked a solid cake, but layered colors throughout, so when you cut a slice there was pictures in it, don't think it worked too well unfortunately.

$1 to the first person to machine me edible bike parts. A lot has already been done in choppers and bobbers and pro streets, but nobody has gone "Step right up and feel free to eat the the mirrors and grips"

Chocolate would machine well I think... But they already have chocolate 3D printers.
Hard cheese might go ok also.
My flatmate makes bread that has a steel like consistency, so that might machine alright, but edible would have to be a loose definition.

[bogan]

hmmm, chocolate flame sliders... :drool:

can you get chocolate in round bar form? I would so do that for a laugh.

[The Lone Rider]

hmmm, chocolate flame sliders... :drool:

can you get chocolate in round bar form? I would so do that for a laugh.

You could get a 22mm steel rod, drill a 10mm hold right down the middle, and a small hole at the top to drop chocolate in. Then shove a drill bit down it, on slow, drop choc in the top hole while a friend heats the steel rod.

You'll extrude choc round bar, if you can get it all to work (and then rapidly cool once it's out of the heated rod).

[bogan]

Reckon it'd be easier to just use a bit of stainless tube, fill with choc, the press an appropriately sized plug into it to move the choc out. And you could put cheries and other black forest goodness into it that way. Could even drill and have caramel filled flame sliders :drool:

[The Lone Rider]

Chocolate handlebars then?

For that matter, is there a market for edible chocolate dildos. You said you were planning on doing projects in the near future...

[bogan]

Installed the MK1 spindle, and spun it up just before, runs nicely! Cuts pretty nice too with a bit of coercing. I have yet to put any bracing on the spindle plate, so there is a lot of flex coming down the Y axis as the plate is only 6mm thick.

Here's some pics, vid to follow once I have added the bracing.

Vibration Finisher works! Need to get more aggressive cone media next time, had parts in for about 6 hours with that stuff. Just gone into walnut shell now for a bit of polish. The plastic cone put a nice matte finish, with a bit of scale like texturing about 3mm size. I'm thinking the walnut should polish that up. Though I've heard one guy got 1hour plastic cone, 2 hours oval steel ball, and 6 hours walnut for a mirror finish. Will just try different media etc until I get it as quick as possible, but it's a case of throw in and come back in a few hours, so all good if the polish step is an overnight one.

The bowl is held onto a bit of ply, and under the bit of ply is a motor with an eccentric weight, which shakes the fuck out of the motor/ply/bowl/contents. The bit of ply is mounted on some vibration isolating springs, then on a heavy base, to try and keep all the vibration energy in the top bit, and stop the fucker bouncing around the shed. It still moves about a little though, which is not ideal, might try screwing it to something even heavier, like the wall.

Ok so its a bit like putting the bowl on my washing machine lid. What are the cone things in the bowl and where do you get them?

Yeh pretty much, cones are plastic and I got them from regal castings, they are about $35 per kg, so hope they last a while.

Cool. Co I could get a old washing machine with manual timer and remove the timer motor so it wouldnt advance,out of balance the bowl a bit so it shakes and glue cone bowl onto the lid to get the same effect. Tard me will have lots of leaking aw380 wm for next to nothing.

Would be horribly inefficient, and probably shake itself to bits, or chew through your floor, but the theory is sound!

You could build a vibration finisher like mine for under 100bucks, with all brand new parts. To put that in perspective, I've already spend about $250 bucks on the tumbler media (cones/shell etc).

Yes im liking the idea and will collect some bits to make one. Just using wm as example but ill make a offcentre balance motor out of used part from work(smaller motor than wm). maybe a old record player with small weight on turn table. That might turn a little slow.
I do like this polisher idea. Ill see what motors are sitting at work

1500 to 3000 rpm is the good range. I added a third bearing on the other side of the eccentric weight to remove the bending moment on the shaft because the shaft looked a little small (7mm).

That sounds alot like electric drill speed. My workmates should keep their vans locked at all times.

[carburator]

that is a lot of weight hanging off your bridge, but i do like how you have done your collet holder..
be interesting to see the life span of your open bearings though?

as for vibration? your using a bridge system on steel legs one that we built like that
we filled the legs with foundry sand to add mass to the unit .. ( normal sand does not work )
though lead shot is good but just as dear..

Yeh, they are big bearings, and I'll run a oil lube system for them and the slides later on, so I'm hopefull they will last for a while, at least until I can offord to replace them with angluar contact ones.

Have considered filling the legs, but I'll wait until I've identified where the main vibration is coming from, and fixed that first. As sand fill makes it a bit harder to modify if required. I think comercial ones use some epoxy like fill to add mass and remove vibrations, probly dearer than sand though!

just nick a scott oil off someones bike at the next rally problem solved haha..
reminds me to lube my chain ( little slack on that )

resin has no weight to it, however it does dampen vibration. that gorilla space foam
is the ducks nuts for doing that works real well in sprint car wings

your using linear slides? you don't want to lube those else the ball race bearings in them
gather up all the dust and crap and chew themselves to bits given that all your slides are
above the cutting area way covers would be fine..

[bogan]

Won't they pick up the crap regardless of whether they are oiled or not though? Plan is to use covers top and bottom, and force foam filtered air into that area, which should keep the dust content minimal, and oil will reduce wear and friction.

I've been having more of a bash at the parts vibrator, upgraded from a 80g weight to a 300g weight today. But now the bigger parts just float around on the top, might change from a horizontal spin plane to a vertical one and see if that makes a difference. Also, does anybody know of a place that sells bowl replacements for commercial units? I think using one of those should get better results than the plastic bowl I got from the warehouse... good old feature creep ;)

I think the commercial ones are more donut shaped, and bits go around the outside while the center shakes the most. A wok would just throw thousands of plastic cones all over the floor!

guess I could find a clear lid, but it'll all be smashing up against it, which is not good circulation either

Well, that was the total of my helpfulness for the year :D as you were!

Hang on...how 'bout a bath tub? Or chop the top out of my munted tank lol

[carburator]

the comerical ones are donut shaped, ( mine is )

the media then rotates around the tub and parts
tumble better

yes parts do float to the surfaced
( had a swing arm in for six hours once bloody thing was like a sharkfin! )

we tend to add more liquid to the shaker and gives it greater distance to
the media ( hard to explain really you want that quicksand effect )

the other thing I have on mine is a VSD ( variable speed drive ) and change
the motorspeed to sometimes get parts to settle into the media..

as for dust and crap out of slides, slide covers are good, don't bother about
forcing air into the area ( have a dedicated grinding room instead )

[bogan]

6 hours eh, that's just a quick session by my standards <_<

mine is just a DC motor on a variable power supply, so I have adjusted the speed best I can. They seem to be going around a bit better now that I have got a donut shaped bowl sorted. Haven't tried it with the plastic cones yet though.

[bogan]

Aha, it'll cut aluminum now :D

Spindle is a bit underpowered, but taking shallower cuts keeps it going alright, and I've got a few plans to fix it.

[ducatilover]

Good progress bro! :niceone:

Milled the first production part this arvo :D came out nicely, and nothing caught fire. Also got a lathe, partially so I can turn stuff, but mainly so I can hook the coolant pump up and run flood coolant on the mill :innocent:

[bogan]

Long time no update, wasn't a fan of the lack of torque with the brushless ESC and motor so I got a 3phase 1.5kw water cooled jobbie. Then took it apart and modified it for ATC.

The retention system uses the spindle motors own drive to tighten and loosen the locking nut (which will be held in place by a simple locking pin solenoid).

First I'll get the overview shots out of the way...

Now the working principals.
http://i285.photobucket.com/albums/ll52/bogan229/SpindleATCmod/SpindleSection.png
Taper (green), toolholder and stub (bronze), locking balls (yellow), locking nut (red), and locking wedge (light blue) are the functional parts. The rest is all pretty standard stuff.
http://i285.photobucket.com/albums/ll52/bogan229/SpindleATCmod/AlternateView.png
Between the Taper and locking nut is a 2mm pitch thread. The locking nut has two drive (locking) dogs which (with a pin) lock the nuts rotation to the housing but allow it to move up and down the axis. This enables the locking nut to both pull and push the locking wedge up and down the spindles axis. When the locking taper is pushed down, the forces the balls inwards, which presses the tool holder stud upwards due to the contact angle. The tapers on the tool holder stud mean when the locking wedge is removed it will push past the balls easily.

Finally got me spline shaper working, works, but need some improvements. Improvement one being a motor for the crankshaft, took a while (and some blisters) to crank em out by hand. The cutting tip needs work, didn't stay true right the way through, but not a bad first go with an angle grinder, will get some 8mm square tool steel for the next one.

That's f-ing neat.
I always thought there were shaped with like a mini gear cutter.so (two sides are done at the same time)

Very nice, good bit of kit that will serve you well over time.

You could make it more usefull in general and more riged for that job in particular by making an under-table support bearing. Means the tool load is supported both ends of the cutting path, you need to be able to demount the tool, though. Delapina used to make keyway broaching gear like that, very very handy.

You can take some of the initial contact load off the tool by chamfering the bore, also helps prevent that breakout damage on the underside eh?

Santa brought me some spare time, so I started upgrading the electronics on my mill. Modular step drivers and a Ethernet Smoothstepper, which is pretty neat. Setup should provide a bit more torque than previous, hoping no more skipped steps.

If anyone wants a TB6560 or whatever the fuck the common thingo is called, free to a good home. 3 axis 2A 24V driver through parallel port.

Show us a picture of your mill bro

Yeh it looks a bit better now with an ally bed in it...

Yup, with the use of a proper CNC mill at work. Rigidity for doing aluminium is pretty borderline, so might look at re-purposing it for plastics/wood, and do a manual mill conversion for metal stuff down the track a bit. Or just get my hands on a swing bed 5 axis :drool:

Ever considered using it with a plasma cutter? Unlimited cutting potential

[ducatilover]

Sweet, will do swappy thingy next time your over here or whatevs.

Got her all running again, then proceeded to break my last 3mm cutter :facepalm: Think there is some setting to change circle interpretting I need to do also, as it was supposed to do a rad 0.5 circle and instead just fucked off in a big arc through my work. Boss :D
Yeah, I have that problem all the time with my mill :innocent:

And 5 years cleaning the cuts so they're in spec :bleh:

C7 ballscrews with a plasma cutter is a bit of a mismatch... Quite like to smash out a 1.3x2.5m plasma table though, just do it chain drive with some decent steppers and V rollers on box section.

Got some more cutters, motion controller and step drive upgrades are working pretty mint so far.

bogan dreams of having the kit and skills to bash something like this together...

So, my normal polishing guy got his dick stuck in a rally car or something, so I had a go myself. Those are sprocket covers and will be anodised then have something pretty cut into em. Behind are various parts for fuel tank caps and swingarm blings.

Good to have got my work stuff out of the garage and getting back to making a few bike bits here and there...

Sometimes things just go a little slowly

Slow is good. My specialty actually.

Nice shot. Phase transfer, you can almost see the molten material jump across the gap at peak current flow.

Where'd you get it mister? Did they have any proper plasma transfer movies?

I got it from the site which has pictures of cats eating cheezeburgers, so no, no proper plasma transfer movies :laugh:

Bit of PC modding, kind of a dick of a job with all the different bits and emulating fan tach etc, but worked out pretty sweet in the end. Though the panels are a bit shittily aligned (the fat nerd memorabilia sitting on top is there to act as a balancing weight, else they jam up) so might do up some ali ones at some point.

My thingo and boby, pretty hand it is too. Will be more handy with a 4th axis on it, soon...

That Alloy plate where the battery used to be might need a design. Do it alloy ok?

[bogan]

3mm thick? does that ok but starts to chatter on bits thicker than 6mm. Draw design up (with measurements) and I can give you a price...

More shed gadgetry...

Finally got around to doing a Vinyl Cutter for the mill, works pretty good, but if anyone wants some done for your shit, call speedy signs cos they are good cunts. I'm just pissing about with sorta stuff so I can say 'i can do that'.

Also did some electro-acid-etching using cut vinyl as the mask, worked pretty mint. Simple as to do as well, car batt + jumper leads + cotton swabs + vinegar/salt mix (and safety gear ofc).

Please post a picture of the van doing a one wheel burnout. Thanks.

I really like the idea of the mod you did with this spindle, I realize this is an older post, I wonder how does it work for you? Did it last long, still running and using it? I ask because I am in the start of building my own CNC router, and really like the idea of an ATC. But they are $$$$. One part I didn't catch, what operates the Locking Nut, once the unit is all together? Solenoid?

Never got around to hooking the spindle VFD to the mill controller, so haven't got the ATC working yet. It works well for manual tool changes by just sticking a bit of bar in the slot and turning by hand; although it really needs a second set of balls on the top chamfer of the pull stud to eject it from the taper.

Nah, still been using it; it just struggles a bit with aluminium, so there isn't much need for heaps of cutter changes.

Last mod to it was a 4th axis, ER40 BT30 collet driven by stepper geared down through a HTD5M belt/pulleys; could put up some pics, but that describes it all really.
