Scooter flywheel on, head ready to accept a combustion chamber. I might bung ot in the CNC for that.

I see a good amount of welding on those crankcases, can you share your wisdom on how to properly do welding on production cases? I have had limited luck welding them, lots of times it turns to doo-doo !!

Cheers, John

I dont know?
I make a solid steel bar that lightly press fits into each main bearing housing, help keep them aligned as best I can. Clean weld area with brake clean, S/S wire brush, emery cloth, pre heat a little then lay into it with the Tig.
I use 4047 rods, seem to work well.

Cylinder back from Heat Teatments, now in T6 condition. This weekends machining job perhaps.

Great progress as always in that shed... just a precautionary tale to everyone about Brakleen and welding though - some years back i was welding a mazda rotary manifold and was using brakleen and my stainless wire brush throughout the job. next day the mazda guy collected the manifold and commented that i looked real bad. after he got home he sent me this link https://www.brewracingframes.com/saf...sgene-gas.html. also a story about a fit n healthy home mechanic that did similar to me and he was wheelchair bound within days. I guess he'll be dead now... Projects are neat but we don't want to fry ourselves. Looking forward to more positive posts!

Heck yes. Brake clean is evil stuff. Never knew.

If I was single I'd come up to the first race Neil.

I am sure Neil's flattered but also married.........

As far as i know NZ CRC brakleen doesn't contain the ingredients needed to produce phosgene gas.
ie chlorinated hydrocarbons ie Tetrachloroethylene.
But i am no chemist...

Wynns is the supirerior product, even if I am a few vodkas from spelling.

Haven't met his wife but judging from his daughter his wife is undoubtedly where the looks come from so I won't make any sort of play for him (unless he wins the first moto and I can't contain myself, ) .

I wonder if I can edit this in the morning if it doesn't seem so funny then, ��

Whiskey, gin and brandy
With a glass, I'm pretty handy
I'm tryin' to walk a straight line
On sour mash and cheap wine

I had a look at the can, it says engine de greaser not brake clean. Always thought they were much the same thing. Either way just make the aluminium as clean as you can I guess.

if its CRC
They both have Toluene
the degreaser also has acetone.
It seems most industrial places it seems use just Acetone

the reason being its a decent solvent and Acetone evaporates leaving no residue.
I can't weld for shit regardless. Plus i am no chemist.

It also looks like in NZ version of CRC brakleen does contain still same nasty shit in it ie Methylene Chloride, its different then the simpiler US version..

Thanks for the tips, will try 4047 next go. Sorry, did not want this thread to become a MSDS and OSHA reg area!!

Slow but still happening. Headers tacked together and in place

Neil, from what we can see, the exhaust is completely finished now. You can move on to the other bits now...
