sorry for the bad scan on that....one day I'll get a digital camera and descent photo-editing software. Anybody know how to re-size a scan and not get the jaggies? (and get it to less than 100k for the AlfaBB?)
Very nice, now you can break out the china and
eat off the engine
Im starting my resto, and was wondering how I
am going to clean all the corrosion off the trim
and engine parts. How did they do that? Was it
with a polishing wheel and some kind of compound?
Did you take the parts to a machine shop, or a
Well, the "beautification" work was simply done as a finishing touch to a long head gasket replacement project. Also got the head cleaned and resurfaced, new guides, seals, & springs. So the big chuncks of aluminum: head, plenum, cam cover, intake manifold were bead blasted spotless. They were blasted by the same shop that did the machine work on the head and they didn't charge me anything additional to clean the parts.
Basically all I did was prime, paint & clearcoat them so they'll stay the same color as when they came out of the bead blaster. I bought new cam cover nuts too and a lot of little things that go a long way towards making it look "new" again.
The rest of the engine and smaller pieces of aluminum were just cleaned with a degreaser and some wire brushes. Since you are doing a restoration I imagine you have the engine out of the car so you'd be able to do an even better job. I think you'll be suprised how good the engine will look after a simple, quick degreasing and scrub down...all of that aluminum oxidation comes off really quickly.
I've seen some beautiful polishing jobs on cam covers, especially on the older cars that had an easier to polish design. Go to www.rossored.com ...Jeff has nice pictures of his polishing work. Its a tedious, arduous project but the results are fantastic. But then again, what Alfa project ISN'T arduous and tedious sometimes!
I guess it all just depends on the look you want to go with....thanks for the comments though! Next year...the interior....
Nice work there on your Spider. I'm actually just getting ready to polish another cam cover for my '78...I had one on my last car, and I really liked it, so I thought I'd do it again, but this time with before and after pics, and time my labor to see how long it really takes. (Um, do I really want to know?) The engine bay on my car is pretty clean, though, so I think it'll be worth it. I also took my Chromadoras to the powdercoaters today, and they're bead blasting my new (old-style) 2 piece exhaust manifold, which I'll paint with silver high-heat paint to more or less match the aluminum.
'67GTV- I use increasingly fine sandpapers on a sanding block for the flatter parts, then wet-or-dry, then a grey scotchbrite drum on a die grinder, then rouge-black, white, then green.
Honestly, it's a nasty job, but it looks SO good when you're finished. Be sure to wear a respirator and safety glasses- the debris that comes off as you're polishing is pretty evil.
Supposedly there is a place near here that will polish a cam cover for like $80 to $100- Developmentally disabled adults do the work, so you're kinda helping to keep them employed. They look pretty good! Photos to follow as I do the job on my cover.
(Ooh, I bet you're all on the edges of your seats!!)
