got back into it - replaced the crankcase bearings.

cool as. has it got the bracing under the seat from the later year models? stops them cracking. i bought some a few years ago for a customer's bike.

no idea, never used it. i did these just to see what it looked like and see how it lasts over time. i think irk posted a comparison at one point between traditionally blasted and hydro/vapour blasted. hydro/vapour blasting is sand blasting with water instead of air.

a single leading shoe it wouldn't worry as one shoe is trailing anyway, but wouldn't a twin leading shoe become a twin trailing shoe if the rotation was reversed?

the vapour blasted heads. really does shine in a way sandblasting just doesn't. the spare parts man i've followed around a couple of dealerships has left the industry, which motivated me to get the engine bearings ordered before he left. some are on back order. the mains are pretty...

i got my gears. so now it's up to me to get my shit sorted and get the engine back together, then get the bike together. next is cutting out the primary drive cover and ordering all the engine bits i need. going to replace the bottom end bearings, and the mains are pretty pricey. need to get...

cool. love the waterjet. the router table is one tool i don't have.

a fellow put an original rear section of frame that everyone cuts off on a facebook page, so i bought it to return the frame to original (apart from the bracket welded on the front). i cut off and drilled out the aluminium bits that had been stuck in the ends of the frame and then cut the frame...

that stand is a great fab project. learning's a lot better when there's cool applications at hand.

he doesn't care in the slightest.

out in the sun a day later. it's a funny sort of colour, hard to work out what it really is. won't really matter once it's assembled and in, you can't really see much of the cases. just hope it stays there.

got some paint on the cases. this is vht sp995 - cast alloy. it has quite a bit of metallic flake in it, which i wasn't expecting. will see how it goes off when it's dry. one of the heads i had chemically cleaned because it was a mess, but now am not sure if i can replicate the cylinders...

when i go to someone who does something i don't i tend not to tell them how to do their job. i expect them to know. otherwise i'd go somewhere else. i'm sure we did gear tooth design at some point in the 4 years of mech eng, but that was 30 years ago and fucked if i can remember any of it...

depends what you call expensive i guess. he did quote me, but i've forgotten how much it was now, a few hundred each maybe. i don't really see it as that relevant. the cost is long forgotten when the result is right. the gear man did explain it all to me, and he says some of the profiles are...
