ESE's works engine tuner

Sunday.
We move along according to plan, but i dunno who´s plan... *lol*

There are a lot of misconceptions about Ethernet cables. CAT5, CAT5e, CAT6, etc, doesn’t say anything about the shielding of the cable. It say something about the data transfer capacity of the cable. Usually this means thicker wires for for instance CAT6, compared to CAT5e.

For advice on shielding, this article is a good read: https://www.truecable.com/blogs/cabl...yI4KYTh8TW75kE

My dad was an old-school electrician so among the stuff left in his shed I found a 500 ft reel of screened, twisted red and black two core - 2/10/010 (2 core, 10 strands, each strand 10 thou ) I believe it was intended for wiring domestic radio receivers to an external antenna and earth point. It could be useful for ignition system wiring

Is the search function broken on this site?

Or explain to me how to use it? Or link to how to use?

Much appreciated

Search works fine, its just a bit fiddly
Search then on drop down "advanced search"

Use "single content type "up top left

Specify its a search by "post" rather than thread at bottom left and add in key words and preferably add user name
avoid common words.



You can also search thread or user via images and then use that to lead to posts.
As below





You can also search using Google or another search engine but add in
Kiwibiker "ESE works engine tuner" in quotes.

I am just wondering what is the best ( this is what I think they are called) 'Truncated Cone Calculator' as I only know for sure the start diameters and some of the end diameters and what angle's I want to use or will I need to dig out Bell's Book and work out manually the templates? or do I need to bite the Bullet and buy EngMod2T so it can do most of the working out for me? and test it obviously.

EngMod does not generate flattened cone dimensions, it has a basic pipe calculator in the code to get you started on a design with your input on the variables.
It is a 1D engine/pipe simulation code only.
JanBros spreadsheet calculator does the same sort of thing , for port and pipe design , but is not a simulator.
There are several apps online for doing cut cones and producing the .dxf for laser cutting.
The trickiest of these is WS Exhaust Designer , where you can manipulate a segmented pipe in 3D animation to generate the cut cones.
I use SolidWorks to cut the cones and fit them using boundary dimensions taken off the bike/kart - that will then spit out the .dxf for each segment.

[husaberg]

the pro ways are the way to make them.
An easy way to draw out simple cones is make a template out of discs the same diameter and spaced apart the distance you want.
you simply mark a start point and trace arround the arcs they roll.
You can use this to make offset cones and even transitions for round to square triangular or hexagon.

SolidWorks! Now I have two different projects I need that program for. I better get it. Are there different levels to the program? or do you have to get the whole thing? This is what I was ultimately wanting a way to generate .Dxf's to send to a laser cutting outfit.

Oh. I will have a look for this "WS Exhaust Designer" It sounds like it would be very helpful in the design phase.

Husaberg, thank you for the search tips.

I still couldn't get it to work. Tried via on this site, and Google way multiple times and ways. I'm in USA, do you think region has anything to do with it? I am trying to search transfer stagger. Used Wobbly, Frits, and Jan for names.

cone layout can also export .dxf files, and is a very easy to use programe to create the cones.
https://www.google.com/search?client...e+layout&gl=ad
I also use solidworks to make a circumference-drawing in which I have to stay with the exhaust and create the hole pipe. than put the dimensions in cone layout and print paper versions of each segment. put them on sheet metal and cut them manualy.

In SolidWorks its easy enough to create an assembly and put in boundary dimensions that the pipe has to fit within. Or another way is to create the pipes centerline sketch , and fit the middle of your
cut cones assembled onto that.
The only issue with the CAD program is that when you cut a thin revolve ( the whole cone ) you cant simply flatten that revolved part in Sheetmetal.
The angled cut will , when flattened , have two lines, depicting the inside , and the outside of the cone end.
Neither line is an accurate depiction of the angled cut pattern shape in reality - and the laser guys would have to remove one of them for the laser software to follow.
There is a workaround, by changing the OD dimensions and removing 1/2 the material thickness = the Neutral Axis or a bend factor K = 0.5 as is usual with thin sheet rolling.
Once you have cut the solid revolve , you can select the outer surface - flatten that , and create a .dxf that is exactly the correct shape to be laser cut with no extra lines.

Hi Jonny

Just confirm you are logged in and are following these exact steps in order they are written and using the same key words
Searches fail at times on KB as they are not single content or use too many words.
