excellent idea for your 'curing' oven!

Oven is working good...
Cleaning cycles on both ovens were run for 2.5 hrs each.

Upper oven before:


Upper oven after cleaning cycle:



Started collecting parts for a first test of Semi-Gloss Black powder.

Leveler brackets, one of which I had previously refinished in rustoleum rattle can black.


The ugly one blasted and 2 bumper brackets too.


Black painted bracket getting blasted.
Note the blasted Mickey Thompson Big Black valve covers in the background... already done and awaiting color!



Casting test pieces will be these bodyside badges.
Black powder will be the backdrop, with a refinished face, then high UV resistant Clear powder over

Badges are more complex... We wanted to test some simpler stuff first.

Here is the gun we used.


Front bumper brackets were a good start.
Powder Coated with semi-gloss black.


Into the oven they went which was preheated to 400 F.



Began to flow out after a few mins.



Curing is suggested for 20 mins at 375 F.


Quick IR test of part temp... it was 375, but dropped quickly.


After 20 mins.... done.


There will be a learning curve, so we are doing non visible stuff first, but looks great.

So more experimentation today.
We are still learning. My buddy, Jeff is a novice too, and we are working together as he has lots of 1960 Alfa parts to coat!
If I do the coating (I want to... never been a watcher!) I cant judge the distances or see the details... so I have to stand back...

We tried a couple of badges today.
Blasted them clean... wiped them down with MEK, and ran them in the oven to outgas at 500 F.




Then wiped them down again with MEK.
Then they were READY!


Part coated...


I think I had enough on... Looks like its fuzzy felt covered!



The word is, that the powdercoat is so thick and hard, you should wipe off the areas that need to be finished differently BEFORE curing...
So, we wiped off the raised areas with a foam brush.
Messed up a couple of times, so had to touch up, so it was PLENTY thick!



In the oven they went!
Felling like Betty Crocker!
Flowed out at 450, then left them at 400 for 30 mins... checked several times with the IR thermometer and it was pretty much spot on temp wise.


Out and cooled.




Next it was the highlight areas... I had decided before to give that a "Brushed Look" to contrast with the polished skin... plus the cast pieces never polish up as well as the skin.
15 mins with some 220 on a block later...



Clear coat over it all tomorrow is the plan.
This hopefully, wil mean the badges will not tarnish and last a long time.

Put them in the mail to me Dave!

So, Bumper brackets are done... Tick.

Front Leveler Barckets were next...
Man they are heavy and complex with holes, and recesses!
Not super pretty, but they will last...


So as a warmup for the headlamp castings because they need the a similar process... a pair of cast aluminum valve covers from an alfa I have...

Outgassed at 500deg F.


Powdercoated until they look "Fuzzy"..



On the cooling rack after curing.



Done, seml-gloss black with the highlights sanded out.

The frustration continues...
Still struggling with the vision, and hope that the stars align soon for operation.

On top of that, when we went to clearcoat the badges, it was suggested to step up to the 25kva gun setting(from 15kva), to ensure the powder is attracted to the already coated areas. When we did this the gun was making an arcing noise form the power supply box...
A call to Eastwood Customer service revealed that this was not normal, and the gun would be replaced under warrantee. The replacement arrived recently, so we can get back to it now, and also move onto the headlamp and grill castings!

So, to keep my mind active...
My original steering wheel was a mess.
I had, by pure luck, found a replacement, but the color is kinda blah..



So the original was floating about the garage...



Time for some investigation.
I wanted to see how it was stitched and how the spokes were wrapped!




The leather cover is one piece, including the spoke wraps.
Here is the subtle skived(leather is thinned to a feather edge) glued joint...

I am thinking to recover it in a two tone rich brown, and cream leather.


With Robyn's help, unpicking the stitching, I peeled back the cover.

The spoke cover area was interesting..



Done.
The wheel rim is an injection molded medium density foam.

What is the wheel made of?
That was my question.

Aluminum... Probably 6061.

So... what must we do with Aluminum?

Have it chromed?

My only concern is seeing your polish jobs I can just imagine. It is a dark night you and the girlfriend are cruising down the road, your highly polished (and reflective) steering refracting light from the dash instruments so it looks like a mobile disco going down the road!

I am not saying I wont do the same. Heck I would even consider doing it this weekend if I could just figure out where I put the steering wheel!

Too funny Dave!

I guess it was more a case of "Do I really want a grubby looking yellowed finish on my steering wheel spokes?" as much as polished.
I might brush finish it, but either way I need to clearcoat the finish to stop it coming off on the hands. Cant powdercoat it either because of the molded rim.


Question....
My Propane tank gauge is clouded over... and the level gauge above the kitchen reads wrong.
I understand that I can replace the tank gauge....

I saw this, matching Teleflex LP gauge...
Wondered if I could make it work...
