Got a good day of work in on the uds today. I decided to paint the ribs of the drum silver and the body green, after a certain football team who happens to stink this year. Here it is with the first coat on and the ribs taped up.
I decided to go with 2 3/4 intakes and 2 1 inch intakes. For the 3/4, I drilled 1 inch holes with the step drill bit and for the 1 inch, I drilled 1 1/4 inch holes. The pipe nipples fit perfectly. I actually had to use a pipe wrench to get them in. Sorry, I didn't get any pics of this part. I spaced them evenly around the drum at 17 1/4 inches and 2 inches up from the bottom.
I changed the 3 inch bolts to 4 inch bolts for the legs of my charcoal basket. That makes it sit about 17 inches high. I also decided to add a grate 1 inch above the basket to grill and place a heat diffuser on. The bolts for the middle grate went in at 28 inches, which is 24 inches exactly from the bottom of the basket. I used a T Square to make sure everything was lined up. After lining everything up, I drilled 1/4 inch holes around the drum in line with the air intakes. I cleaned up the rough edges on the interior of the drum with a grinding bit on my Dremmel. I then placed 1/4 x 1 1/2 ss bolts, nuts and washers in for the cooking grates to sit on.
Next, I went to work on the lid. My
weber kettle lid didn't fit. I decided against cutting a 2 inch ring off of my kettle and used a 1/8 x 1 3/4 piece of aluminum. To measure the interior diameter, I used a piece of 1/16 aluminum flat bar I had and clamped it to the interior. I marked it, then placed it on the 1/8 piece to get an exact measurement.
I then took the 1/8 piece and cut it on my chop saw with a metal cutting blade. This is where I went overboard. I drilled 1/4 inch holes just under the lip of the drum at 5 inch intervals all the way around the drum. My thinking was it would pull the aluminum bar as tight as possible to the wall of the drum. Probably overkill, but too late now.
Next I took the 1/8 flat bar and clamped one end into the drum. I then kind of worked the rest in and into a semi circle shape. I used another clamp and clamped it in halfway around. I pushed it straight against the wall and worked it to have a half inch sticking up out of the top. I placed a clamp inbetween the hole I was working on and the next hole. I then used the existing holes in the drum as a guide and drilled 1/4 inch holes into the aluminum. I secured them with 1/4x1/2 ss bolts. Every 4th or 5th hole I used 1/4x1 1/2 ss bolts for the top cooking grate to sit on.
After it was in and secure, I added high temp silicone to make it air tight.
I then drilled 1/2 inch holes, which you can see in the above picture, for my temp probe intakes. I'm using brass grommets for that. I put tape behind it and put a second coat of paint on the drum.
I should have it all finished tomorrow. I'll add the final pics tomorrow as well as my final cost.
