Question about CMT Saws

1 Answer

I have a 20 year old table saw of unknown manufacturer (but all machne parts are metric). The spindle pulley (mounted on motor spindle - it accepts v-belt from motor pulley) keeps coming loose. i think the socket screw holding it in place is close too loose to prevent it from loosening with use. Any ideas of how to re-tap the pulley? find the manufacturer (if still around?)

Simple, there are two options:
1) buy a new pulley from any hardware or home improvement store.
2) If threads are stripped from pulley, either retap with next larger size tap, or redrill new hole and tap with same size as the current size. Note the best way to keep pulley on is to have a set screw over the key and another at 90 degrees from keyway. Note 2 - Are you sure current pulley does have two set screws?

I was recently given and older Craftsman 10" table sawa. It worked great for cuttin some 2x4 and now all of a sudden it will only cut part way7 and than stops, and it smokes--Help!!

The problem could be one of the following:
1) dull blade, in which case replace with a carbide-toothed blade
2) underpowered or old/faulty electric motor
3) faulty/worn belt, in which case replace with new belt
4) The pulley on either the motor or the saw arbor (where the pulley attaches underneath the saw near blade) could be loose. Tighten down set screw.
5) The saw fence isn't set straight causing the wood to jam as you push it into the blade. Check this with a framing square and readjust so it is at a 90-degree angle to the front of the saw table.

You could post your request at this link, but most likely you'll have to search ebay or the like to find one. Try to look for a manual there (or try and get the part #, then search google for that part #. I suspect they are common to many different saws and a universal replacement could work...
Maybe someone who welds aluminum could repair it?

I have an old craftsman table saw that I inherited and need a part that is no longer available from sears. It is a motor mount bracket at that how i describe it any clue on how to get one of these? ...

Dan, Take pictures of the area of your saw where the motor mount would be mounted, and any other mating parts (like the motor). Measure a few things like the distances between some of the holes. Go to Sears and look at the saws they have on display. You will probably find something similar that you would be able to use with little or no adaptations. Write down the model number, go to this link and look up the part. Please vote if this is helpful. Good luck, Al K

Pulley on motor tilted to left and belt keeps coming off

jim, Yes. The motor should be mounted to a bracket with 4 bolts. Loosen these, align the pulleys, then tighten the bolts. You can see the four elongated holes in the base of the motor at the following page. Scroll down until you see the 9 product diagrams. The one labeled "Motor" shows the four holes in the base of the motor.!retrieve.pd?modelNumber=315.228390&pathTaken=partSearch

Motor base needed for 10" table saw

My 10" Craftsman saw started life with a 1 hp motor. I'm on number 3 motor which is 1 1/2 or 2 hp. 1 hp seems to weak. The pulley diameter is about 2". The motor needs to rotate as the blade is moved from vertical. Mine is mounted to back of the blade arbor. The mounts needs to be adjustable for adjusting tension to the belt. McMaster Carr would have the start of a motor and base.
