This was a quick hack since I got tired of holding the spindle lock wrench while unscrewing the drawbar. Holds the spindle in place and I can unscrew the draw bar with one hard.

Quick release mechanism that uses a few magnets I found around.

2 flat bars bolted down to another one with M4 grub screws 50mm apart acting as the locking pins.
