When you say with a Torch do you mean heating it up and then trying to hit it out? or cutting it out with torch?
thanks
Both.
A torch is a last resort for me. Too much damage possible. A carbon air arc is more precise but not many people have the equipment needed.
There are several methods to remove pins. You just have to find one that you are comfortable trying or that you have the equipment for.
The most basic method I have used is drilling a hole through the pin. Sometimes this is enough to get the pin out. If you drill the hole big enough you can get a saw blade into it and cut grooves in the pin to allow it some give. Either way be very careful not to cut into the frame. This however takes forever so patients is key.
If only drill the hole part way through the pin this will give you a hole for a rod or bolt that then can more easily be hit with a hammer.
You can weld on high strength all-thread to the pin, place a large socket on it that is bigger than the pin, then using a high strength nut and washers, tighten the nut and pull the pin.
After drilling the hole all the way through, you can weld a rod or angle iron inside the hole and try to hammer it out. The weld will shrink and should help shrink the pin.
Good luck
