Tips to extract cylinder sleeve anode on 225 AK3

[brettmarl]

Replacing my anodes as part of 800hr service.

The ones in the cylinder sleeve jacket are tricksy. Main bolt unscrews but machine bolt and anode left behind and quite stuck in there.

Any tips to safely extract? Feel like I need some kind of puller gadget. I tried pulling on one screw but the zinc just broke off and remained in the hole. I'm a little afraid to drop either the bolts or zinc fragments into whatever is behind them...

Image-uploads aren't working for me - I put photos here:

Update: got them out, was able to pull out the screws breaking a small hole in the zinc and then carefully dremel and vacuum out the rest of the zincs left behind. tedious job, but it's done.

I usually use a 14mm drill bit, those anodes are always stuck firm.
