Spring pin removal - cutting wheel ?

[mopetta]

I tried to remove the spring pins on my A7. One side worked well, but the other side still does not move.

- I heated up the casing and cooled down the pin
- Used an extractor (large enough tube with big washer) to tear the pin out
- Used a hammer and a drift punch

but still there - any other ideas that might do the job ?
or is it now time for the cutting wheel ?

thanks, Oliver

Yes.

The pin very likely is worn and has grooves in it.
You may find jacking up the casing very slightly and using a big punch with a Big hammer shifts it.

I had a similar problem on a Big Seven.

I thought I would make a mess with a cutting wheel, and decided to try a hacksaw first.

Thinking it would be hardened, and not cuttable, but ..... worth a try.

To my surprise, the hacksaw worked.

I've found when fitting them, a pair of stilsons on the spring and twisting the spring a little can take the tension off the pin. Might be worth having a go like that whilst still giving the pin a good clout...
