I had to google that, and no, I am going to use a spray clear that I think is up to the job. Will let you know how good it is in 1-40yrs. YMMV!
You can get DTM (Direct To Metal) lacquer developed for alloy wheels on cars which is probably what you have? It's OK if your finish isn't mirror polished and just Scotchbrighted but still lifts if chipped. I was doing my Swing Arm in it but I'm now going for clear Cerekote I think
Did you sandblast them yourself or get them done elsewhere?
I did them myself, only took about an hour but fiddly as you can imagine. Am going to hit the inside with some oven cleaner then a thorough wash out and immediately reassemble the bottom ends.
I’d be interested in seeing your sandblast set up and knowing more about it, eg, home built? off the shelf? etc. In fact I think @NOODS built something a few years back iirc. I don’t want to hijack this build thread so perhaps in a new thread? I’m sure there are others would be interested too.
Right, so I have a freestanding blast cabinet which I currently have glass bead in. This is nowhere as abrasive, not even close, as carborundum or garnet. I have had the latter 2 in there as well.
And I have a cheap and cheerful, but effective, total loss setup which is basically a handpiece with a drawhose. Obvs this is messy but outside on our gravel driveway is perfect. Practice makes perfect and although I didn't, it would pay dividends to youtube the hell out of it. Also pays to have a good water trap for the compressor which falls into the category of, the bigger the better! Mine is mid size I guess?
Am I right in thinking then the difference in pressure between the glass beads and air in the bucket and the fast moving air from the compressor as it exits the gun, causes the beads to be drawn up the black tubing above and then ejected with the air?
Correct, the venturi effect. So there are many variables involved. It is just practice to set it up right, or so it at least works!
Is that poor mans hammerite smooth silver?
Lucky for me I remembered what you said and attacked the bottom before giving up!
Looking brand new again !
Not bad for a 50yr old motor that was covered in corrosion when I got it and I had it out in the weather since then about 10yr ago! Inside, the bottom end was in really good nick, just a busted kick start return spring.Looking brand new again !
Are you sure those forks can handle ... errr .. a big lad...?
Great job dude!!
So I finally got going again on the old SL's, partly inspired by the big money they are going for on our TradeMe site. Not that I have done a lot, sandblasted 2x heads, lapped in some vslves and then painted the assemblies. Hoping to have motors complete and in frames soon.
