New machine day - Surface grinder

[@Ziknazoo]

Thanks for posting this! Your comments about the grinder not having enough power hit home. My Boyar Schultz had the same problem - it worked, but it was not able to take more than about 5 tenths without slowing down - sometimes even stalling. I opened up the motor junction block and found mine wired for 460VAC! I'm running it from a 220VAC VFD. Rewired it and it has WAY more power. Thanks man! My machine is very similar to yours including the blower except mine has a hydraulic pump for automatic X and Y feed (which works!)

Hi Stan, I have a Boyer Schultz grinder too. Great machine! I had to replace the LoveJoy coupler between the spindle and the motor and that was all it needed. I don't have the dust collector on mine but looks like a good accessory. I use a phase converter and works great! Thanks for the video! Regards, Reid

[@daviddominessy]

I'm glad to see you bringing that baby back to the land of the living, Stan! Grinder hands live on!

[@oxtoolco]

Hey Stan, Nice score. We had the same machine but without the dust collector. Looking forward to its resurrection. Cheers, Tom

[@KnolltopFarms]

Whoa, that is amazing, 3 five gallon buckets? They must've just built the collector and then just let it...collect, LOL! I too love the design of the logos on it,,,as a former auto body and paint shop owner, I have seen allot of badges, stamps, and logos, and this one is quite detailed and artfully done. I hope you got over the sniffles that dust gave you, I'll bet you found some nice black "statues" in your nasal dust collection spout :) Aloha and thanks for the share...Chuck.

[@KnolltopFarms]

I just finished the video and learned it was a factory install, so I wonder how long it takes to get 20 gallons of girt? I've done a few small forgings in my past and it made me think of just what all of that stuff is and if it would be worth trying to melt down to make something? I know that there would be heaps of smoke from the oil, and dross from the grind stone grit, how much of that do you think is metal in your experience? Sorry for the barrage of questions, but you did ask two, and while I wouldn't have been able to answer them at least I can count that high! :) Aloha, Chuck.

[@TheFeller1554]

Cool new addition,I have a similar one in my shop without the sweet dust collector. I believe on that oilier where the flex goes into the other electrical box there should be a variable timer connected to the wires leading to the oilier. The box by the manual plunger is a small oil pump. As the machine is running, the timer sends voltage periodically to the pump biased on the duration you set the timer for. As you run the machine you will see the plunger rise very slowly, and when it reaches the top of its stroke you will hear a pop, that's the plunger releasing a shot of lube.You just have to keep messing with the timer to get the right amount of oiling. If your machine is quiet and you forget to turn it off the oilier will make a huge mess(don't ask how I know that). Also if you run your machine infrequently the charge will leak out of the plunger past the seals, and back into the tank. So you would need to manually oil it. Hope this helps.

[@ShadonHKW]

Thanks for the oiler tip, inside the box by the plunger it looks like a small clock motor, I dug around but couldn't see any evidence of a timer anywhere. Any idea what voltage these things are? I would just be guessing @ 110V, sure would hate to find out the hard way. Regards, Stan

[@myideas8548]

Great review/info. I am looking at one of these machines, so your video really helped. Thanks.

[@FredMiller]

Sweet machine! Really looking forward to the rebuild / restoration. Thanks for having us along on the initial tour... Fred

[@ShadonHKW]

Hi Fred, I was mostly looking for a machine that was ready to go to work, and this one fits the bill with a minimum of fiddling, a restoration isn't really planned at this time. Thanks for the view and comment Stan

[@outsidescrewball]

Hi Stan... Nice new toy!...lol Still learning on my machine so I will be waiting to see your machine up running and producing work! Chuck

[@ShadonHKW]

I would like to see some workholding tips and tricks as well :)

Nice Stan, can see it’s been a while since you acquired your Boyer Schultz. I’m going back through all your videos and work my way forward with your grinder evolution. The Abrasive 1 1/2 is in the shop now. Also need three ph. I’ll be watching them all 👍

[@ShadonHKW]

Wow, your going way back.

[@nickvee9468]

I'm reconditioning my 618 1a hydraulic (purchased 4/27/18 $450). No vacuum or flood which i want to add. also did not have 1-shot or plumbing. Trying to figure out how the table was getting lube if any. I still have visible flaking but haven't gotten the cross feed up and off yet.

[@flatheadronsgarage7345]

Nick, think I can get a one shot installed on my ol Abrasive 1.5. Would be nice, drilling on this He makes me a bit apprehensive since I don’t know how they have it drilled internally without a manual, still looking for one.

[@nickvee9468]

Yep, we all buy our own problems... lol

[@MrKidkiller159]

Flathead Ron's Garage the abrasive 1 1/2, I have too. it took me awhile to get it up an running so far so good.

[@k5at]

Nice machine Stan! Thanks for sharing.

[@keldsor]

Oh, a nice machine - I'm looking for one myself, but I'll go for a "cooleant type" so there should be no problems with that filthy dust - it's all over and I hate it ! - long to see it running !

[@richardhaisley1]

The dust collector motor doesn't run in reverse because the grit and grinder dust go to the right. The nut is normally left hand so reverse could spin it loose.

[@dalmatiangirl61]

The reversing switch was originally wired so that it gave the option of grinding with, or without the dust collector. A new owner could not figure out why it would not reverse (because that is what a reversing switch is for), so he "fixed" it by re-wiring it.

[@danbentler9742]

Looks good Stan - seems like you got your head pretty well bolted on and thinking right - espcecially so with VFD - you have all the basics covered well and then some. Yes you will need individual overloads for each motor. In your case I would think twice on grinder and blower on same VFD - if BOTH the motors AND the loads are identical no problem.. The motors do not care provided you do not run less than 10% rated RPM without added ventilation - as you know the motor fan is not fast enough to cool. However the fan curve on the blower is going to be your main limitation / concern I think. Some studying and head scratching may be good thing. Blower CFM vs RPM measurement may be good thing to do. FWD REV switch. That does look factory for sure. Why they left FWD REV labels on beyond me IF they did this to let your run grinder only OR grinder and blower together. Check rotation of each motor in "FWD" and "REV" is my first thought. Agree do not run grinder in reverse - saws grinder wheels go across shop at speed of light when they get "loose". OILER Wonder if that is a solenoid that shuts valve off to turn off oil flow when machine is stoppe ?? Looks like a gravity setup to me so do not understand why need for motor to drive a pump or a stirrer ??? Dan Bentler

[@ShadonHKW]

Hi Dan, After a little more research, the forward / reverse switch is wired to run the grinder by itself, or the grinder and dust collector together, the factory just left the stock nameplate on the switch. The reason for installing a VFD is simply to generate the 3rd phase, I will not be using it for speed control. Standard parameters, coast to stop, 10 second ramp up, no DC braking, everything will be running at good ole 60Hz all the time. I did a lookup on the oiler, it is 220V and pulls 8 watts, it needs to be energized when the spindle is running, easy enough with the programmable switchgear in the freq drives I use :) Thanks for the well thought out comment! Stan

[@danbentler9742]

Agree with all except dynamic braking. Seems handy feature for an E stop. I suppose even if you could brake within one second you may not likely avoid destruction of a grinding wheel. So maybe a mute point - braking two motors I am just not sure about - would be interesting to fiddle with though. Might need a separate brake resistor so not worth it in long run. Dan

[@not2fast4u2c]

A very interesting machine

[@davidgrimble3649]

my machine is a tool grinder.spindles on both ends.necessary to faciliatate the setups[limited table travel]mine does not reverse .but i have right and left wheel adaptors.the advantage to have multiple wheel adaptors is you can dress the wheel and change wheels without having redressing the wheel.also easer to change wheels [with hub]than to use spanner wrench and switch wheels and redress wheel to balance.i'm new to u tube don't know how to respond other than this.

[@phuzzz1]

Hi Stan, Congratulations on the new tool! I can't wait to see how you restore it, I have to agree with you on wondering why it would ever need to run in reverse? Mike

[@ShadonHKW]

Hi Mike, A restoration isn't planned at this time, just giving it what it needs to get running properly at this time, sorry. Cheers, Stan

[@davidgrimble3649]

i have a brown and sharp #13.it has right and left hand spindle adaptors.i would think if you used a hight hand spindle[running in reverse] the dust collector would be useless unless you moved your dust cover.i have a large supply of spindles if yiu need any

[@ShadonHKW]

Thanks David, any advantage to grinding in reverse?

[@horkinyorkin]

+Shadon HKW blow your nose before you make a video!

[@jamescrombie2320]

Very nice acquisition. I looked around and found another one that had been reconditioned vintagemachinery.org/photoindex/detail.aspx?id=12199 If you haven't seen this, you may be able to get some more info on the pump off of him. Good Luck
