This year I have had the opportunity to replace ten pinblocks, and I have learned a few tricks along the way. One of the most valuable suggestions I would give to another technician is "use the right tool for the job." In the case of removing fitted pinblocks, use a jamb saw.
A jamb saw is a circular, flush-cut saw that is used for cutting the jamb and casing out of a door without marring the floor. A jamb saw allows you to get right down flush with what you are cutting without worry of nicking the surface you are cutting against.
When removing a fitted pinblock with a jamb saw, I would suggest the following steps:
1. Drill out the vertical dowels in the far right and left sides of the block
2. Clamp a stout guide above the stretcher (letting it overhang 1/8") that the jamb saw will follow--make sure your clams do not hang under the block in the path of the saw
3. Set the jamb saw 1/8" from flush
4. Cut the pinblock along the stretcher
5. Finish the corner cuts (along the stretcher) with a hand saw
6. Use a chisel to pop the under sides of the block along the case
7. Save the block (corners still in tact) as a reference
8. Smile, pat yourself on the back, wonder why you haven't thought of that before, and take a break--five minutes of hard work and you deserve it!
