The home brewed tool is made from 1-1/4" pipe parts from a plumbing supply, Home Depot in my case. I couldn't find black pipe in 1-1/4", so I used galvanized pipe.
(1) 1-1/4" pipe flange
(1) 8" - 12" nipple
(1) 1-1/4" pipe cap
1-1/4" pipe flange measures about 4-3/16" or so, and has to be reduced to about 3-13/16" (3.812", maybe closer to 3.850"). You can use a grinder to accomplish this, but I had a lathe handy, and the skills, so I assembled the nipple and flange, gripped the nipple in the 3 jaw chuck, and turned the flange down, removing about 3/8". While I was at it, I also trued up the flange face, but that wasn't really necessary.
