2x8 Arch Build

[DocsMapleSyrup]

I'm planning on using 4" sewer pipe split in half and drilled with holes to bring in air at different angles to increase turbulence. Why did you cut down on the number of holes in the bottom firebrick. Maybe that would be easier for me to do. I still have options.

I ended up changing my grates. No more sewer pipe. I found out it's too hard to cut and drill. I ended up using 2x2 angle
V side open at top with AUF coming up through the grates and out the holes I'm drilling in the firebrick.

Firebrick are much easier to drill 3/4 hole if you drill 3/8 hole first.

What kind of drill and bit?

I have a 1/2" Bosch hammer drill and it drilled a bunch on hammer and never broke any several years ago.

I have a Bosch Bulldog. Takes Ed bits. Drilled a 1/2" hole last night no problem

Folks,
Another option for grates.
Local syrup equipment supplier built these.


By the way the arch your building looks good and I think you have welded a thing or two before tackling this arch?

That is one complex grate. Holy cow. I couldn't imagine cutting and welding that thing. Here are a couple photos from when I wrapped it up last night.

Does anyone know how to attach the Buyers trailer door mechanisms that fit in the end of the 3/4 inch black pipe. They are made out of pot metal and the black pipe is of course steel. Can it be MIG welded? What are others doing or have done? Thanks.

I think most are drilled and bolted, that's how mine is
