I don't think reel adjustment needs to be difficult, Deejay. You can just put a piece of 0.002" brass shim in between reel and bedknife at each end, press the reel against the bedknife, and tighten the screws. Then rotate the reel to remove the shims. You will probably ruin the pieces of brass shim each time but it wouldn't hurt the steel reel and bedknife, and the pieces of shim can be quite small - perhaps 1 cm square. This is very similar to the procedure for adjusting the clearance between coil and flywheel.
