TECH TIPS

SLOTTED DRUM MACHINES

DID YOU KNOW THAT A MAJOR PROBLEM LEADING TO CHATTER IS LEAVING THE PAPER TIGHT OVERNIGHT. THIS COMPRESSES THE RUBBER AROUND THE SLOT. The rubber never goes back and eventually makes the slot wider causing a bigger bump when the drum turns. 

DRESSING A DRUM:

Spray glue sandpaper to a very flat surface. The surface has to be big enough and flat enough to hold the sander wheels and the 80 GRIT paper. Next Put 4- 80 grit shims in the drum slot and remove the fan belt so you can hear the drum contact the paper.  Decrease the tension as much as possible. Start the machine and touch the drum to the paper very slightly for a few seconds and see if the drum is hitting evenly across the drum. If it is hitting on one side use the adjustments on the machine to level the machine so it cuts - grinds the drum flat. Now it will take at least 15 minutes to slowly grind the drum - dress the drum. GO SLOW! This will remove some surface imperfections and remove dimples in the surface. This will help to eliminate chatter.

Belt Sanders

Most important!  They must cut FLAT! NO CUT SIDE. If they cut heavily on one side this will push the paper to the other side and you will compensate by adjusting the tracking to keep the paper in the center. This will wear the drum on the cut side and the top roller will wear quick on the other side. The cone rollers will wear out and sand belts will rip up faster.

EDGERS

Poor dust collection can be a clogged or a bag that is too fine of material. Try the OEM bag.  Also if the edger is adjusted too high in the back it will not pick up.  A slight tip to the right side  1 O'clock position may help.

If the armature is worn heavily or uneven save the armature by having US or a good shop turn and under cut it.  PS We charge $150.00 to do a tune up and extra $75 to turn and under cut.
