Bofors help - Calling the Brains trust

I agree Tony an air chisel with a flat punch will get loose stuff that 20 ton press will not touch. I've gotten stuff apart this way by blocking the chisel body in place with just enough space to let the thing tap away, generally let it tap full preasure first to see if you get lucky. If not then I turn the air preassure down and just let it sit there and vibrate away. Reason for turning the air preasure down if you are just going to let it hammer is to keep the punch from heating up or spreading the body of pin out.

Obviously if you get any movement try switching directions of your attack.

With that much iron attached to the pins should make a nice noise.

Dig a hole and use a 5 lb short handled sledge. Unless you are parked over concrete that is.

For anything seized i always swear by heat. Heat followed by oil will suck the oil in to where it's needed. Mike's point about the bronze bearing is valid, so you don't want the pin glowing red in this case.

I got lucky with my Bofors....Brad did all the bullwork.

Hi Tony - seriously though what heating method have you used. You need a large heating device like the flame torch I recently bought, that way a large area can be heated without the heat rapidly dissipating. Regarding the bronze bush, the melting point of bronze is 950c so you had better have your little glass thermometer with you.
