    Default A Tale of Two Craftmaster Table Saws

    briefly two craftmaster table saws, the tilting arbour belongs to jacques who has asked me to bring it back to useful life and a tilting table that i decided to renew for the heck of it

    jacques' tilting arbour now has a motor mount, motor and wiring and is operational. however severe blade wobble indicates that new bearings and some minor machine work is required. Like the beaver 1200 and 2200, the motor doesnt tilt with the arbour, the motor just slide along a rod to provide some semblence of belt alignment. it does work at a bevel angle of 45 degrees with quite a belt twist!! but work it does!!

    the tilttable saw has had new bearings and i had to machine the spindle down for a 1/2 inch bore pulley it was so severely damaged at that end from a loose pulley. the main body has been cleaned up and painted, tabletop(severely rusted) has cleanedup nicely, saw is now partially assembled ready for arbour runnout check

    pics will follow when the batteries are charged

    pics!!

    first is the tilt arbour(jacques saw), added motor mount and electrics
    blade wobble indicates a need for bearings and arbour machine work, minor stuff for a 60 year old saw

    next is my tilt table, neat compact little saw, new arbour bearings installed

    ok here's the little tilt table on a rescued refinished rockwell stand, needed a wood shelf for bolt alignment, motor is an old 1/2 hp repulse induction motor, not sure which way it rotates yet but its gonna need a long belt!!

    I sure would be more comfortable with a wider base on that saw.

    so back to jacques's tilt arbour saw

    the mechanical stuff is sorted out for the motor

    time for disassembly and some paint

    got some new bearings and reassembled the arbour bracket

    paint is being baked in the driveway!!

    you can see the three parts that make up the cabinet, the "trunnion" piece that slides on machined grooves on the front piece, all pretty ingenious and somewhat similar to the beaver 1200

    the motor doesnot tilt with the arbour(like the beaver 1200 and 2200)

    more pics to come when the paint's well baked

    so here's the tilt system, everything hangs on the front cast iron cabinet piece, similar to the beaver 1200

    but the craftmaster "trunnion" slides in a semi circular track machined into the cabinet front, very simple and very effective for a small saw, a little graphite and its very smooth

    and reassembled

    the arbour bracket is infact very tight, so accurate bevels should be easy, accurate depth of cut? yet to seen

    pretty solid construction actually, far better than than the modern crap from craftsman and crappy

    with a little care and attention, this little saw gonna make a sweet little dado/groove cutter

    new bearings fit great, i'll check runnout on the blade flange later, btw bearings were 6203's very common size, 8 bucks each

    My saw looks exactly the same. Does that mark on the inside of the back say "8TA2"?

    I also see that you have taken out the large pin that holds the trunnion to the arbor arm. Mine seems frozen in place. Penetrating oil does seep through the cracks but it doesn't seem to budge. Is it worth it use some vice grips to work it loose? the screw on the bottom of the arm there seems to have worn a grove around the middle which keeps it from going side to side.

    remove the screw completely then tap the pin out, i used a socket and a hammer

    the groove is meant to be there, the locking screw engages the slot to prevent lateral movement but allowing rotation. take the locking screw out of arbour arm too

    and a closeup of the guts!!

    the arbour bracket is locked to the arbour rod with a setscrew that engages a flat machined on the rod. the rod can rotate in the "trunnion" for height adjustment and is retained by a locking setscrew that engages the groove in the rod

    all very nicely machined and tight and smooth in operation

    also shown is checking arbour runnout, before the bearing change, runnout was severe, the blade wobbled at least an eighth and the arbour washer was over 20 thou. now the runnout at the arbour is 4 thou, better but could be improved on, i did try installing the other arbour washer and the blade nut, tightening them, runnout is now 3 thou!!

    so a little machining will be required, my beaver 3200 has less than 1 thou at the arbour, or i'll try a beaver brass washer instead, got one around here somewhere

    decided to keep going on the reassembly, i can pull the arbour later for a little lathe work. fastened the side panels loosely, flipped the saw over to check the blade to mitre slot, easy adjustment, measure blade to mitre slot front and back, twist the cabinet front a little, check again

    i had it perfect in two "tweaks", i may have play with it a little more after i get the arbour trued up

    assembled the aluminum sides properly and rechecked blade runnout, about 15 thou, not bad its was over 200 before, but my 3200 is around 2 thou at the blade rim

    next job today, reassemble the motor setup, cut some wood

    and its up and running

    the 1/4 hp is barely enough to rip 3/4 oak, but i have an old 1/2 hp somewhere

    ripping is easy and clean despite lack of power, crosscutting is perfect

    it turns out that the mitre guage i got from bob doesnt fit either saw, it has a 3/4 blade, the mitre slot is 5/8 same as my beaver sander guage, so an issue to solve!!

    saw runs very smoothly and quietly, cuts are decent considering blade runnout, fence system is nice and square, very easy to set

    so next job is to correct the runnout

    I did not think that so much work was involved in tuning an old table saw, but I really appreciate what you are doing Steve.

    i missed the bit about "groove around the middle", there shouldnt be one. the set screw in the arbour bracket should be ligned up with the flat bit machined in the pin. the pin rotates with the arm. the groove in the end of the pin is for the other locking setscrew that has a small section of the threads machined off

    file the middle of the pin all around to remove any burrs and it should come out easily

    well everything has to square and parallel for a saw to operate correctly!!
    then of course there's setting up the camera, taking shots and posting them, that takes more time than the tuneup work its self!!
