So i bought a vintage Tester horizontal band saw. I stripped and repainted it, changed out the motor from a 3/4hp 110v to a 230v 1hp 3 phase, added a digital tach with an inductive prox and 3 trigger points on the drive wheel, wheel is 10.625 diameter so the tach should read 11.120 in per trigger as 1 rpm or 33.36in per rev of the driven wheel, close enough that i can call it 3fpm vs 3 rpm. I have installed a TECO vfd, push button start, and push button stop, and a remote pot to adjust speed. The saw originally had a toggle switch that was actuated when the saw cut thru the material and tripped the switch, what i want to do is replace the toggle switch with a prox sensor that in turn acts like pushing the momentary stop button. Can i wire the NPN N.C prox in series with the momentary N.C stop button? or will there be some issue with lifting the saw off the prox that would cause it to restart, or will it be ok in that it would need another start pulse to restart?image000000.jpg

I'm guessing you can set the parameters for that input to prevent restart on closure- check the manual

The manual is vague. maybe i can program S3 as a stop also
I got it running perfectly, Teco L510 VFD, Digital surface speed readout, Speed potentiometer, push button start/stop, Dual Laser cut position.

Looks a very well made bandsaw good job restoring it.
Is this saw capable of cutting in upright position? maybe with some modifications?
 
Wowsers! Fantastic job on the saw. I especially like the laser.
 
I love the idea of the laser. Is this stock or did you add it custom?

it also cuts in upright, you just pull the lower pin on the feed cylinder and raise it to vertical.

I added the laser's, cost was 8.00 dollars for a pair of lasers and 7.00 for a pair of 2 x cr2023 battery holders. and i made the brackets from a peice of 3/4 x 3/4 x 1/8 wall, square aluminum tube. the only thing left to do is making a new driven wheel. the original was butchered by someone with a grinder and the edge that holds the tire in place was chipped off 3/4 of the way around, got a steel burnout i just need to get it in the lathe and bore the center for needle bearings and turn the profile on the O.D
