Process for Yellow fog light reflectors?

May 30th, 2010 at 01:05pm Under metal finishing

Hi.
I’m new to the forum and looking to have my vintage fog light reflectors re-plated. What kind of plating is the familiar yellow on fog light reflectors? Is it zinc chromate? The reflectors are steel and I’m wondering if they have to be chromed first and then plated in yellow…

Thanks!

Adding a 240V Outlet Without a Co-Pay!

May 29th, 2010 at 01:05am Under metal finishing

Yes!, today I wired up my outlet for my oven in the garage and did not have to pay a Co-Pay!!! the thought of wiring up a 240 circuit for my oven had me scared. Once I got the panel off and saw how simple it was I was relieved. Carefully plugged in the breaker, cut my wire to length, carefully attached wires to the breaker, the ground block and neutral blocks without zapping me across the room. Then I feed the wire through the hole and mounted the box. wired up the outlet and attached to box. Turned on the breaker and then plugged in the oven and had the light! Turned on the oven to 350 and away it went! I’m back in business!!!!!!

Plating Stainless Steel

May 29th, 2010 at 01:05am Under metal finishing

Caswell’s British Fasteners offers a couple of sizes of Spring Washers I am in need of, but they only have them in Stainless Steel.. The "factory correct" finish of these pieces on the car were originally Black Oxide. In the interested of Preservation, as well as restoration, I’m plating all the car’s fasteners in "Black Zinc". That said, is there anything one can do to Stainless Steel (that won’t ruin it) so it will accept the Zinc Plating and following Black Chromate??

My NON-Folding Oven begins!

May 29th, 2010 at 01:05am Under metal finishing

Well I have picked up the beginning of my larger oven. It will be 4×3x3 and I hope to generate enough $ to build my 24 x 24 shop in the back yard so i can then build a 8×8x4 oven. So far I have a total for $67.30 for the mineral wool and the stud. Plan on getting the material to skin it for free and use a $30 oven for wiring, controls and elements.

Does my math add up?

May 29th, 2010 at 01:05am Under metal finishing

OK installing a 60 Amp CB for my 240v Oven outlet. You want to keep it at 80% so I take 48A x 240v = 11500 Watts.

Is that correct? I can use 4 2880 Watt elements.

Do I win?! :D

powder coating heat treated aluminum

May 27th, 2010 at 01:01pm Under metal finishing

Newbie alert!

Sorry, I know this horse has probably been beaten pretty well, but I can’t find a definite answer for the life of me. I have read MANY articles and posts, but none seem to have a concrete answer.

I would like to be able to powder coat aluminum bicycle frames, which are made from 6061 and 7005 (for the most part). As I understand it, 6061 is heat treated, but 7005 may or may not be heat treated, so you must assume it was.

Due to the low availability and low color choice of low temp powder, is it possible to cure regular powder at less than 270 F? That’s the general figure I came up with from various sources to not affect the heat treat. It seems aluminum is heat treated at a much lower temp than other metals, so anything over 270 will affect the heat treat. Maybe cured for a much longer time, or is 270 F just not hot enough to get a full cure, no matter how long it’s baked?

I figure this is a little advanced for someone that’s never coated a damned thing before, but this will be the bulk of what I do, so I’d like to know if it’s even feasible before I blow hard earned cash on equipment.

Thanks for any info folks!
