Now that's what I love to see!
Yankee ingenuity, and adaptability!
So I'm wondering, does the adapticators sit on the old rack ways in the original OKJ?
I'm thinking it does, but it sure would not be the first time I was wrong. ;)
Very nice modification. Who ever you collaborated with was a good fabricator.
Only one small change I would consider, well maybe two.
A way to bolt down the back side of the two rails. Just a 1/4 x 20 in each one. Still removable, but solid, stable.
And a keeper on the sides of the the lower rack. o_O
OK, I'll explain. When you drag out a rack in most ovens (or smokers) there is a way to prevent the rack from tipping.
Ovens do that with a doo-dah you have to tip the rack up to continue to withdraw it.
You might even, if you consider doing it, put a screw or two where the square tubing is so the lower tray can be withdrawn to flip meat, then slide it back in. If sliding the lower tray out for that is a consideration.
If not withdrawing the lower rack during use, then it may be a moot point.
But Great modification! :)
