barrel pin removal...
Hi All,
My buddy and I were cleaning up an RTG cocking tube...
we got the tube off and cleaned up with an end mill and a dremel. Turned out great
Now I have the trunion with a cut off barrel in it... How can I remove the barrel pin? would it be easiest with a hydralic press?
What type of drift or punch do you all recommend...
My first attempt I chucked it into a vise and applied force with an arbor press... the arbor press gave enough force to start flexing the punch I was using...
Any suggestions?

I took the remaining sheet metal off the trunnion. I used a center cut endmill and a dremel. So now I am down to the trunnion and a cuttoff junk barrel.
I used a bench grinder to knock the welds down.
Now I can get it square in the mill vise.... I will give it a try... Carbide only huh... HSS is all I have on a sunday!
Thanks men...

Just to let you all know...
I have a 2nd RTG cocking tube... these are in great condition... the cocking lever has almost no wear marks on the metal.. The first one w dismantled had a green handle that is a little discolored looking... The 2nd is perfect! The trunnions and cocking tube metal are all in great shape. Ww have beeb scheing bolt gaps with a few different bolt assemblies.. the trunnions are comparing favorable to the best ones we have.

Oh Yeah... I tried a short punch and a hydraulic press yesterday. I could not get it chucked well enough I guess... also the press was a POS.
