I should put the engine into a kids quad and give it to my niece for christmas I could just imaging the look on my sisters face (joke)

Was doing my monthly raid on a friends scrap yard and spied what looks like an 80s xv1000 its only good for parts but most of the running gear is there, if no one gets back to me at qld.tsv.game@gmail.com it will go to crusher, suh a waste. so plz let me know if you know someone, it will cost the current scrap steel price per KG which is stuff all.

Sold mine as it was never going to get finished. It's only worth something if it's the chain drive TR1 version. Shafties can go to the dump.
If it is the chain drive version, let Pete Sales in Palmy know it's there.

No, angular clearance between the faces trailing the cutting edge and the cut profile. Sharpening a drill the face you grind needs the trailing edge to be clear of the cutting edge, yes? That angle should normally be 3-5 deg. Top rake for alloy should usually be quite high.



Cool. Shapers are almost a lost art. I did my time on a fckung massive planer, fond memories of making swarf 1/2" wide x 2 thou thick x 8 ft long.



That's actually a bit tempting...

a while back i repaired a gear tooth, built it up, ground most of with a grinder with a 1mm cut off (a bit naughty) then i finished it off with a digrinder straped to the lathe tool post.

May have to use on of these in the next few months, scary, haven't been on something that since i was only a fitter. Its called a quartering lathe, very few still exist even fewer working.



This is the one we hope to use as its closer than the one at glenbrook.

Are the family into traction engines ?

If it's a crank repair, I'd have thought that provided a good center can be found, easier these days on a CNC as you can lay the wheel flat...

My dad is retired and spends alot of time doing thing for feilding steam rail, anyways the WAB they have, he crank pins are now under tollerance and flogged, i suggested a few cheap options but they want to do it by the book...meh

I even told them i could do it without even taking the axle out..shesh

Do they ever crack test anything ?

We moved back to the UK after 28 years abroad a while ago. For various reasons, incompatibility with british stuff, helping my son etc. I left a lot of gear behind, so almost starting from scratch. Currently (not really started) using a 3m square workshop attached to the house. Apparently, it's dashed bad form, what, to store acetylene in a residential area. Has anyone advice, experience, caveats to offer on using propane for bike frames (say; 3/4" or 19mm to 4"(!) 100mm x 16swg or 1,6mm steel), please?

I found just going up a tip size made up for the slightly cooler flame, worked fine.

Slight change in welding technique required but it didn't take long to nail it. Brazing light sections was more or less the same.

'Course, it's not a bad excuse for buying a wee TIG...

intregued about operation, would be worth a look

nothing wrong with a good bit of slightly older machinery
