Power tool and cutter grinder
A few days ago by chance I happened to reconnect with the guy I bought my shaper and power hacksaw from about 3 years back. They belonged to his grandfather so he was rapt when I showed him photos of the shaper being used and now living under a cover rather than a layer of dust.
Got talking and the end result was this old Power T&C grinder turned up today with another machine.
Looks to be the same size style as the Cincinnati #2.
Apart from the surface rust and old electrical gear that will need some work it’s in pretty good condition mechanically so will be a good platform to build on.
Only the one basic workhead.

All in good time Kryn, I didn’t want to distract from the TC grinder
I was surprised to find that it’s got ball bearing ways on the X traverse. I didn’t expect that on a machine that at a guess would have been made in the 50’s before Repco bought Power.
Probably not ideal that it ended up with a chain over the table but with the whole COVID lock down I didn’t have any input in the loading.

Nice pick up. Looks like you got the important basics. I've just finished making 3 attachments that fit to the workhead spindle namely an attachment that holds ER32 collets for endmill sharpening etc, attachment that a small 3 jaw chuck screws on to and an attachment that contains a lathe toolpost that I can clamp HSS / Carbide tool bits and /or holders in sharpen. I'll get a pic tomorrow. Happy restoring

Thanks hpa1.
I hope you’re right about it being a solid foundation, otherwise I’m going to cop it big time from my wife who thinks I’m just wasting valuable workshop space with such a huge useless bit of scrap metal
Looking forward to seeing a photo of your attachments.

Something else I've just noticed is that the table only moves laterally. While the head is on a large column that has the motor underneath like the Cincinnati #2 - the Cinci head is fixed to the base and the table moves in the Y direction.
On this one the Y axis movement is achieved by the head being on a separate table that moves in/out. I don't think I've seen another TC grinder with the same design - all the ones I've come across have had both X and Y on the table.

My T&C grinder is of chinese (pre covid) manufacture, branded Wuhan machine tool Co. It is set up similar to yours, work table x axis movement only and grinding wheel head is a seperate table to give y axis and grinding head is on a column which has around 400mm up & down travel. I'll get a pic of it too tomorrow - stay tuned Steve

T & C grinder
Good find Steve.
I have a Cinci 2 in roughly the same condition. With all the electrics kaput I'm thinking of driving the wheelhead from a BLDC motor mounted up top. It's a lot easier than a rewire job and cheaper. Give me a message if you want pics of indexing fingers etc.
Regards
BC

Thanks BC. I’ve got a copy of the Cinci manual here which has good illustrations of the accessories but I’ll give you a yell if/when I need more!
For electrics I’m thinking probably a VFD running the high speed winding and reducing the frequency for the lower speed.

T & C grinder
Hi again Steve.
I was thinking about the VFD path too till I looked at the WW2 motor. Both insulation wise and momentum are a worry. I have found that with a pissy 1/2 HP motor when I crash the wheel and work, all that happens is the wheel stalls in a cloud of abrasive grain. This has saved my face a few times. With my Cinci I will drive the spindle off the rear taper and have the wheel mounted on the front via a shaft extension. I also have a high speed spindle that rides on an extension casting to get better reach.SAM_0655.jpgSAM_0656.jpgSAM_0657.jpg
The pics tell the story. 1st is of the extension spindle on my Tos grinder. 2nd shows the Cinci drive pulley fitted. 3rd has the Cinci high speed spindle and extension casting. These help to get the wheel over the table without having to swivel the top table. From memory the firm I last used for a DC motor was Motion Dynamics in Sydney. Price is OK and they had controllers as well.
Regards
BC

Thanks for the photos BC, and good point about the crash aspect.
I was looking online last night for where I could get a replacement bellows/gaiter from, and found these guys: Bellowflex - Bellows and Covers for industry applications
Looks like they either have or can make anything you'd ever need. Haven't contacted them yet.

On the 2nd pic of the cincy with the drive pulley. Appears to be the flat belt drive pulley for the internal grinding spindle.
What are the width and diameter dimensions please as I have to make one.

Steve, we were typing at the same time.
I have an Elliott no5? T&C grinder and the circular rubber bellows are torn at the top. On that website, I was thinking that their moulded or welded and vulcanised versions would be the most dust proof.
Hopefully the Power and Elliott machine have the same size column. May be a common size.

Hi Guys,
A treadmill motor with its controller might be suitable for the spindle motor. I have a couple that I've salvaged, one is 180 volts and 1.5Hp the other is also 180 volts and 2.2Hp. Both are rated to around 5000 rpm.Best Regards:
Baron J.

Power tool and cutter grinder
Toggy - the diameter where the bellows sits on mine is 216mm (8.5”)
Fully down it’s 40mm edge to edge of the bellows, and 230mm fully up. 11 ribs, 20mm wide.
I’m going to send an email off to them and see what the options/costs are.
The current motor nameplate is hard to get a good look at when installed, but after faffing with my phone camera and a mirror I reckon it looks like 1/2 HP. Definitely dual speed 1440/2880 and 1.0/1.2 amps.
It lends itself to being driven through the access panel opening in the spindle casing
Steve
