If you're having a problem
setting-up, aligning or maintaining your Shopsmith equipment, you should
contact Shopsmith's Technical Support Staff (NOT Smitty).
old sanding discs
My recommendation is that you use artist's rubber cement. Be sure to butter the surface of the steel disk and the surface of the sandpaper. Allow both to dry thoroughly (probably 15 minutes or so). Then put the two together and press firmly to adhere them. To remove, use rubber cement thinner (the best brand is Bestine).
unsquare jointed edges
First of all, it's vital that you maintain a constant, even, downward pressure throughout the cut...and on both ends of the board. Be sure the FeatherGuard is adjusted to provide adequate pressure against the face (or edge) of the board...forcing it into the fence so it can't move away during the cut.
If you're right-handed, start by licking your fingers (for traction) and positioning both hands (always use push blocks, if possible) on top of the leading end of the board. Maintain a steady downward pressure on your left hand as you use your right hand to walk the board through the cut.
IMPORTANT: Be sure that all downward pressure is exerted downward on the INFEED table (ahead of [BEFORE] the cutterhead). If you start to push down on the board over the top of the OUTFEED table, it will tend to lift the board off the surface of the INFEED table, causing the taper cutting you're talking about.
As you get toward the outfeed end of the board, begin to shift your right hand to the end of the board to provide forward pressure as you leave your left hand on top to provide the necessary downward pressure. Let the FeatherGuard maintain your inward pressure as you continue to provide steady downward pressure.
Another thing that could easily be affecting your cuts is having your Jointer Knives set too low. They should protrude from .001" to .003" above the surface of the outfeed table when properly set. If this isn't the case on your Jointer, this is your problem. Your Jointer Owner's Manual explains how to set them properly.
