Heres the tools I used to mount these with.
1/4" USS tap
#7 drill bit
Center punch
All hooked up.
Later on I will get some 2-1/2" tubing and make a cleaner looking hookup.
Some older clear hose is all I have right now.
I'll also need to get two 2-1/2" blast gates. Hoses are hooked up to one 4" gate. That's all I have to do the hookup with.
Made a trial run and it really does a great job on dust and chip collection. I had no chips on the table anywhere.

The first leg there on the right acts as a starting pin.
