Now you're just showing off Steve (i'm just jealous)
Time to unlace the wheels so the hubs can get cleaned up and polished.
The rims are nice but the hubs definitely need some attention.
Looks like the nipples were actually yellow. They appeared to be clear zinc on the outside.
Only two rusted ones. Next to the valve stem where water must have gotten in. Other than that there's just some surface rust that should blast away.
Rear wheel is first up.
And then the front.
Started cleaning the fenders to remove the layers of mud and dirt from underneath.
Got through the mud and realized there was some sort of rubber undercoating. Never ran across that before. Is this factory? I'm thinking it is.
Same on the rear fender. Well preserved. Just a little bit of surface rust. Cool!
Most of the undercoating peeled up with soda blasting. I'll blast it some more and finish it up.
Is your soda blaster a cabinet style or the non recoverable/outdoors ?
Just and old cheap siphon feed blaster. Works pretty good but I have to kick or shake the hopper now and then to keep the soda flowing.
I bought me a soda blaster Last night to see what it will do on my 450. What pressure you running?
Around 70-80 seems to work good.
Not all the NOS Bridgestone parts out there still look new. This rear sprocket was all I could find.
She's not real pretty but she's got nice teeth!
It will need to be stripped to bare steel and re-plated.
All of the cables are in pretty rough condition. The only NOS cables I could find were the tach and speedo, the rest will have to be rebuilt.
Been polishing the aluminum parts up one by one. Bead blasted the top tree and then started wet sanding.
Shiny fresh metal starts showing up.
And eventually it gets polished. A beautiful alloy and casting from 1967 lives on to look new again.
Have you considered vapor blasting for a step in the polishing?
I'd be considering hiring day laborers ;-)
More parts sent thru the will be was machine. How many gigajoules does it take to run that thing? You transported that top tree to seconds after it came off the buffer.
I'm sure you know Flanders but here a link for other old schoolers
I remember when I found out that cables were bike specific. walked into a certain motorcycle shop and asked for a clutch cable. "what bike".... hey, just a regular clutch cable. "I gotta know what bike"... ok.. Bultaco model 85, 1972-3. I might as well have asked for fresh weasel meat
I know a guy who knows a guy...
I have not. Mostly because I have a bead blast cabinet and don't have a slurry blast cabinet.
In fact there are no vapor blasting outfits in the state that I am aware of.
Sure would be nice to have wet blast cabinet but they are kind of spendy.
Finished up on the rear shocks yesterday. I had originally soda blasted the best looking 2 out of the 4. Then I noticed a slight difference between the two sets. All the same dimentionally but I had picked a mismatched set.
They needed to come apart anyway to finish cleaning and remove the baking soda from under the covers. That's one of the things about soda blasting. It will find it's way into any opening.
I took them all apart to select the best pieces and have a matched set. A strip of inner tube and an oil filter wrench worked great for removing the upper eye and cover.
The upper cover is threaded so it's a jam nut for the eye.
Now the shocks can also be checked for dampning.
Cleaned up all the best parts and bead blasted the top eyes too.
Ready for reassembly.
Good to go.
Is the goal here the same as the 900, to keep all factory?
Unless by some miracle a set of expansion chambers from one of these old race bikes shows up!
