a drill press is very useful in making holes in the reciver for the hardware and rivets,..
you could use a hyd. press but it is not nessary for removal of either the barrel pin or barrel
ive gotten all mine out with a homemade shim,.pin punch,.and 16oz orange ball peen hammer,..12in brass drift for barrel removal
hope this helps
find a big/thick enough washer that will come fulsh with the rest of the trunnion,...chop it up so it will not hit the pin,..you may need 2-3 washers and some tape to keep it all together while you hammer the barrel pin out.
being these are polish and not the rommy "g" kits you should not have a problem getting things to move.
suggested tools include a grinder(not neccary,.. but way more fun,..and faster to boot),..a dremel with fiber re-enforced cut off wheels,.a set of pin punches,. brass drift,..a good hammer,.vice,..anvil or other good hammering surface,..small and large files,..wd-40,..penatrating oil,..anti-seize,..cutting oil (for drilling,.so bits dont break),..a propane torch wont hurt either.
im up in schuylkill co. near pottsville,.i have a krink kit i have to de-mil,.. but i am still lacking the tools to assemble,. such as a hyd press,..trigger guard rivet jig,..rivet squisher,..barrel press set up.
if your wondering yes i have built my own,.....
it is the one on the right,..in fact it is my first completed rifle.
i have the know how,..but lack the tools
