12 ton H frame...
Has the more than enough power to do the job...I don't think a 6 ton will do it because I have come close to maxing out my 12ton on some ROMY's..
Also you need the added length of a 12ton H-frame when pressing in the barrels.
IMHO based on my personel use...
Also..
YOU MUST soak your pin atleast the night before..PB blaster or Kroil..I did not do that on my first build and seized the pin inplace..It moved a 1/4in and stopped.
Had to drill it.
I have this one from HF
12ton H frameDon't go cheap...Atleast when it comes to a 6 or 12 ton...
There are more 12 tons out there than 6tons or 20 tons...Why...
Because 12tons work for removing and installing pins and barrels and making flats....
Also...One of the biggest reasons that made it work effortlessly was that I was using Ak-Builders tools....
Barrel Installation and Removal Kit,,,Adjustable Trigger Guard Rivet Jig,,It is not a shameless plug but these work and you can always sell them when done.
