alrighty then, today efforts.
first things first, a spot of tig brazing to attach the alloy pulley to the chrome steel driveshaft.
a few things to bear in mind, massively different melting temperatures of the material makes life much harder, plus i'm really not good at this tig malarkey. one day i will get some lessons, they are badly needed...
you can see me improving as i go along the part, i was appalling at the start, and just simply terrible at the end.
the start..
the middle, getting better...
the end. starting to look like it should.
i say starting, im aware its still awful... defo a running before you can walk situation.
the thing i learned is you need quite a wide arc rather than keeping it really tight like welding, and you need quite a lot more amps than you think. that first pic was around 40amp the last i was up to 90. i was welding on ac, it seems to work better.
so that done, i need to sort out the tensioner arrangement. so i added a second tensioner. this has the effect of pulling the belts away from each other and stopping them flapping..
using the lathe to take the ridges off the pulley so it doesn't tear up the v belt..
this is the arrangement i ended up with.
i moved the original pulley a fair way to the left, and flipped the other one upside down and welded it face to face. belt is now nice and tight and not flapping about at all.
now, it works, and id be happy to use it as it is. but...
electric start..... should i?

I can't comment on your TIG, mine was complete rubbish the few times I tried [eye & hand problems, but I'll persevere], but I'd try to reroute that power(?) cable in the fourth pic...just in case.

ok, you made me do it.....
minimum prep is involved with this. literally knock off the loose paint, de-grease and key, prime (not even high build) and paint.
prep, or lack therof)
primer
topcoat (some toyota blue i had knocking about)
lacquer (2k as i need it to be oil and fuel resistant... and i have it kicking about...)
better?
