In selecting a motor be certain the motor has good quality ball bearings in the drive end.  If you use a motor with bronze bushings, it will not survive long.

One club member here had both run from one motor, and used step pulleys to change the feed rate.

Grayco,  If I'm seeing things correctly, you have a spring holding the washer onto the blade arbor which would help the blade stop "in a pinch", but what about the drive for the vice that might keep going unless its driven off of the same motor?

No, that is my carriage/vise drive.  This assembly is on the back of my saw.  This has a back plate (attached to the shaft) a plastic disk (about 1/4" thick) the large sprocket, another plastic disk, a tension plate, a spring and the loading nut.

Thanks for the pictures, Kurt!  I love seeing the flowers you find in the wild on the other side of the world.  The Dancing Crane Cobra Lily is especially beautiful and that last little white guy is so cute!   :icon_sunny:

Lowering the voltage on an induction motor will not cause it to run slower but it will cause increased amperage draw resulting in a burned out winding.  This is why brownouts burn up refrigerator and furnace motors.

Went up to the cabin on Sunday morning. A dreadful day, raining most of the day.
But saw some weird and fascinating blooms on the way. There seems to be always something new to dicover.

Trees that are in full bloom (no idea as to name)


Some iris, I presume


After finding out the name. "Dancing Crane Cobra Lily", I had to get a picture explaining the dancing crane in that.
Single stem, branching out to form the leaves, giving the appearance of wings.....


Found this cheater. :) very small, creeping along the floor. Needs to stand out, so produces between one to three white leaves to increase chances of detection.


But the prize for weirdness, must go to this fella (no idea about name)

Nothing special as such? OK, lets have a closer look


No wonder, that one feels watched at any and all times. Even plants are watching you...... :) :) :)

That's a great idea Steve but I don't think it addresses irockhound's problem.  Incidentally I've owned a Lortone LS-10 for a long, long time and it's cut many hundreds of slabs with no problem save one: Crown of Silver Psilomelane.  That's a topic for another thread. 

But the problem with at least some Lortone saws is that the feed mechanism is operated by an electric motor that's independent of the blade motor.  The two operate from the same power source but when the blade motor fails the feed motor keeps running because the power doesn't shut off.  The answer lies in some method of cutting power to the feed motor should the blade motor go kaput.  Unfortunately I'm not enough of an electrician to figure out how to do that.  The power line goes directly to the feed motor and that's connected by a separate cord to the blade motor on my saw.  I guess Lortone figures that motors last forever.  Fortunately for me I haven't had irockhound's problem...yet.

The new pic looks too shiny to match the original, i think i missed again.  I still have a bunch more green slabs to go thru, including many different Serpentine.  So i'll keep looking.  At least i'm having fun looking thru all my old pics that i haven't seen in awhile.

I found another candidate which looks closer than the other pics i posted.  This slab was listed by the dealer that i bought it from as Peacock Gold with Bornite, Pyrite, Chrysocolla, Copper. and Quartz.  See what you think.  So many green stones and so little time.
