I think I need to find a better way to remove the pins. A drill press seems like a good step, but even that isn't a clear answer. How do you guys remove the pins? Do you save the bushings?
I found brass rod at a Hobby Town. The large was all most perfect the smaller was a little small bit works. Do you have one near you?

Good tips everyone... Sometimes some saks will need a little bit of persuasion... especially those old and dirty ones...Here’s how I mutilate mine...1. Center punch the pins2. Using a Dremel like rotary tool, drill the pins until the bushings spin free or if not, approximately deep enough that it doesn’t go through the outer liner... very crucial if you only need to reduce a single layer3. I use 2.5mm drill bit on all but the middle pin with bushing... 2mm drill bit for the middle pin with bushing4. Additionally, I drill the center pin without bushing a little further (but not going through the outer liner) with a 2mm drill bit just to make it easier to punch through. 2.2mm drill bits are hard to find in my area...5. Use a nail punch (close to similar diameter as the pins) tonpush the pins through the bushings and layer per layer... sometimes the pins are softer than usual... using a smaller diameter punch will just simply ruin the pins.6. Arrange the removed layers from top to bottom... easily done if removing layer per layer...7. Take pics with mobile phone... handy when its time for assembly...8. For 93mm saks, I follow Syph’s tip. Drill and push out the center pin first...Sent from my iPhone using Tapatalk
Good tips, J-man. When you say "drill and center punch the center pin first, which center pin? (the center pin with the bushing? Or the center pin (what I called the 'spring pin') without the bushing?)
... sorry Jack This is totally normal even for the second mod.When I decided to do my first mod I've prepared for the worst after reading a couple of SAK mod threads here Apart from the excellent advice already given I found it very important not to rush things and rethink any next step.And building a simple jig for re-assembly is a very good idea.PS, if you get stuck at re-assembling the scissors layer then I found a little trick to get it done (see below).I've used a punch/pin that is thinner than the scissors layer to push back the spring before adding the scissors.Then the scissors can be added pushed down far enough so that the spring stays in place.You then keep pressing the scissors down while pulling out the punch/pin.Hope it makes sense Good luck and don't give up.
