69 BSA bobber project...or...the cure for wintertime madness! - Page 18

Hawk Medicine · 04-20-2010, 01:16 PM

Yeah...

I had a model shop that was attached to an anodizing business and they refused to anodize cast parts.

It seems that you cant really cast aluminum without adding trace elements of other metals or something like that and the impurities will either ruin the anodizing, causing it to come out with tiny spots that look like dust or dirt in paint or if the parts not really aluminum, cause an EXPLOSION!

They actually did some small castings for me but they were never perfect.

YZman · 04-20-2010, 01:36 PM

Yep My other place just got back with me and they said the same thing. No cast aluminum. Said they would be afraid of ruining my parts if they tried.

Oh well

This stuff looks like it might work:

Here's a recent post in another bike restoration thread; this guy's using clear coat on some polished aluminum parts:

The problem I have experienced with clear coat is that if the part is exposed to gas the clear coat will come off (sticky mess). I have had luck with a clear coat product that is fuel proof/resistant. Can't remember the name right now but you can get it at most larger auto stores.

YZman · 04-21-2010, 08:32 AM

Someone was telling me, and I do remember seeing it, on that "Trucks" or "Extreme 4x4" show on spike some product that they put on aluminum rims that bonded with the surface and mud and brake dust would litterly bead up and roll off.

But I cant seem to figure out what it was or if it would be usefull in this situation.

also a coworker was telling me about Duracoat products and it seems interesting. Might be worth polishing up a small chunk of aluminum and coat it to see how it fares.

Can you get powder coating in clear? I'm not sure what factory aluminium truck wheels have on them but it seems pretty tough and resistant.

ZoopSeal

Don't know how it stands the heat though.

You might be onto something there. Says its stable up to 400 deg. I dont figure that motor gets anywhere near that hot

Jason F. · 04-27-2010, 07:58 PM

The Zoopseal looks interesting. It lists engines as a use so it might be able to handle the heat. I will have to look into that for my project.

YZman · 06-11-2010, 07:37 PM

yea I know I know... Ive been thinking the same thing. I have a list of about $1500 in parts that needs... well $1500 to get the parts. Then Ill be stylin

But in the meanwhile my kid keeps breakin his bike. My Vstrom needs new chain and sprockets, truck needs ball joints, and my wife needs divorcin. And somewhere in the midst of all that I want to take a 2 week vacation on the street bike. All with a 10% pay cut at work.

So soon I hope to show some progress again. Just gotta get that thing called life straightened out 1st.

anonny · 06-11-2010, 09:05 PM

Powder coat clear, if the parts will stand 400 degrees f for 10 minutes. Now heres the deal for you YZ..... clean them religiously clean, mail them to me.... I powder clear and send them back... you get back to building.

I hope you get everything sorted out. I'll stay tuned (quietly

Looking forward to seeing this build completed. I found this thread while searching for pics/ideas for my next project, a BSA bobber much like yours, and spent the last 2 nights at work reading it. Hopefully, my starter bike will be in a little better shape. I must say, the pic of the old tail section in the snow was one of the best replies I've seen in any thread. Bravo.
ADD/OCD may keep you up at night fretting over some tiny detail, but it keeps you from a trial and error loop that costs much time/money.
