I have this new gearhead drill press at work. It works fine but the way the barrel switch is wired seems backwards to me. Is there an easy way to reverse the wiring?Trying to change the wires on the barrel switch seems a bit harder than changing the wires at the motor.Can I just move the V1,V2, U1,U2 wires in the box near the motor to change the direction?If so, any suggestions?

Reply:If it's 3 phase just switch two wires at the breaker panel unless there's other motors on the same circuit then don't as they'll then run backward. Better get someone qualified to do it at the drill so the smoke don't leak out.MikeOl' Stonebreaker "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw

Reply:did you check in both high and low gear? some machines spin in reverse in one of the speeds.but yes,you should be able to do it the motor.Last edited by filetobeef; 06-24-2020 at 08:49 PM.
Reply:Is there a manual available for it? I have seen quite a few grizzly manuals and they are great when it comes to schematics...***DANGER***This is just a guess!!! so don't do it unless you check the switch with an ohm meter FIRST to confirm operation of the poles!!!!! My guess is switch the U's 1 with 2 , 2 with 1 and the V's same thing....
Reply:I felt it was backwards as well. But i just got used to it. It’s muscle memory now.www.FirehouseFabricators.comZachLincoln 210mpLincoln SW200Hypertherm Powermax 45xp2x4 CNC Plasma Table.

Reply:Flip the switch handle over if it will and almost accomplished the same thing unless it is keyed to that position which it may be.I guess though it isn't even the markings you want fixed but rather clockwise on switch equals clockwise on the quill.Did it come with a schematic. Check out what the drum switch is doing thoroughly first. Sure don't wanna fry something.Last edited by danielplace; 06-25-2020 at 12:01 PM.
Reply:Hi newbie here and found this thread. I have the same model and am hoping there is an answer one day. Thanks all.
Reply:If you have a motor wiring schematic I can help you out no problem but you need that to be certain of the changes needed to get it flip flopped. I did find it but it only shows how to wire what is exactly there. The motor wire to proper switch connections but not actual connection needed to compare the forward to reverse actual wiring and without knowing that drum switch I don't want to say do this and it is wrong. I will study it further and see if maybe enough clues to be pretty certain I will post. Here is the diagram. I do a lot of electrical motor controls but not enough often enough to know the wiring inside out. Someone even more adept to the standard drum wiring and switching of single phase motors that are reversible. I do more 3 phase but have done a bit of the smaller stuff that is single phase. I am 90% sure you want to flip flip U1 with V1 and flipflop U2 with V2. That is different than the U1 flipping with U2 and V1 and V2 flipped flopped that was suggested. Still a guess.

Reply:Yep, simple if you have a schematic handy
like I said earlier.. probably just a v's and u's swap... but without it in front of me to verify where the wires go or at least verify the switch poles I can't guarantee it

You still have to make a guess. That is only making it slightly more educated but still no way to positively confirm from it.It may in fact be your earlier suggestion too flipping the U's 1 & 2 and then the V 1 with 2.

Ie... just switch wires on post 2 and post 10 of the spindle switch... I think
Reply:Yes, much better pic
thanks... and yes pretty sure 2X10 flip will do it as the way the caps and everything else is wired show it is a common center coil on the motor.
** Unless the spindle switch is really weird on the inside
