Cooling Rack  3                                              08-2018

 

For the steel racks I'll be using some High Heat automotive paint. The can says it's good for 2000 degrees.....well....I don't know if that's true or not but those racks won't see anything over 400. The instructions say that any parts that are not exhaust pipes can be baked to a given temp, which will help keep the paint from discoloring. I'll talk more about this later.
 

 

 

 

I took my parts out to the paint booth and gave them two coats, with 30 minutes between each coat.
 

 

 

Now it's time to put some polyurethane on the wood pieces.
 

 

 

I'm going to use two of the holes to help me hold the pieces.
 

 

 

Here you can see what I'm talking about. This way I can apply the clear finish to the bottom surface first (while I'm holding it), then place it on the nails to do the rest.
 

 

 

Here is what it looks like put together. Now it's time to add one more thing to the bottom rack.
 

 

 

I'll be using two 1/4" diameter ball bearings for the bottom rack. The reason for this is because the bottom holes on the wood pieces are 3/8" from the end. If the U shaped rack was placed into those bottom holes, the whole thing would sit at an angle. What I need is something to attach to the bottom rack that's 1/4" in size so the rack will sit level. I talked with Tracey about this and we agreed that the ball bearings would be fine.
 

 

 

Here I'm welding the ball bearing to the rack. This went pretty fast and was easy.
 

 

 

After painting all the racks in my paint booth, I started the curing process in our household oven. I wondered if this would stink or smoke while doing so but everything went smoothly. The instructions say to bake your parts in stages: the first being set at 250 degrees for 30 minutes and then you let them cool for 30 minutes. Now you set your temp to 400 degrees and bake for another 30 minutes, and then cool again for the same amount. The third step is to bake at 600 degrees for 30 minutes, but I didn't do this last step so we'll see what happens.
 

 

 

Here they are after spending some time in the oven and they all look good. If fact, I couldn't tell the difference before or after heating, which is a good thing.
