Thread: Little Grinder?

Anyone know of used one of these.

I have absolutely no idea what one of those is, but it looks a lot like one of these

Jones & Shipman 1014 Cylindrical Grinder, Capacity: 8`` Swing x 24`` Betwee Auction (0003-5001443) | GraysOnline Australia

I have no idea what one of those is either.

It's clearly a cylindrical grinder with motorised workpiece mandrel and a sprarate internal grinding spindle. Looks like a beauty!
Nice find. If you have use for it, and it is available at the right price, grab it.

I have just purchased a similar grinder (a lot older though) and am currently cleaning it up. See my thread "Van Norman No.2 Cylindrical grinder".

Oh, and I have never used a machine like this either.... can't be that diffcult
Cheers,
Joe

Meadowbank TAFE in Sydney has or had two grinders very similar or the same as this. They were (from memory) TOS brand manufactured in Czechoslovarkia in the late 40's and early 50's. They were good, robust and versatile machines, I ground up the spindle housing for my as yet unfinished Quorn tool and cutter grinder using one of these machines. The internal grinding spindle was driven at high speed by a thin flat belt which was removed for normal external work. This belt appears to be on the machine bed at the right hand end of the picture. Hope this helps.

Metalman, I think this is more sophisticated that that. The high speed internal spindle has it's own motor - visible right behind the fold-down spindle. The flat belt you spotted is for that drive.

All great stuff thanks gents.

few more pics

Hi Joe, I should have been clearer in my description, the TOS had a separate motor for the internal grinding setup as you said this one has, you can see the large pulley to the right. The belt only fitted properly when the internal grinder was setup.
Sorry for the confusion. Mm.

That looks like a TOS 2UD cylindrical grinder. Demco were their agents in the sixties.

Hi Ray,

Looks very similar to Joe's I think Joes might have an extra attachment.

Two words of advice... "Grab it"

The three phase conversion to single phase can use the cheaper V/F drives like Huanyang.

Have a close look at the motor name plate, see if it has 240V, if not, pull the covers off the motor terminal block and see if there are six wires. If there are six wires leading into the motor, then you can rewire the motors to delta, if not, then you will have to get a motor rewinder to locate the star point and bring out the extra wires. It's a 10 minute job.

Don't waste time considering fitting single phase motors. For grinders the difference in surface finish between single phase and three phase is noticable.

Regards
Ray

Thanks all

You gave me a flashback in time. I just checked an apprenticeship attendance card (Still have it) & I also attended Meadowbank Tech back in 1960.
The TOS Cylindrical Grinder I worked with was located near the Tool Store in the Fitting & Machining section of the Tech, One of the last buildings.... a walk down from the car park.
Not far away, was the railway line & when a train went by a slight vibration would be imparted to the finish of the workpiece.
A beautiful grinder. We were allowed to do some "Foreign orders" & get marked accordingly. I used the grinder for making Sine bar roller pieces & a vertical micrometer pillar, ground after hardening.
Please lets know, about the time, you attended Meadowbank

Hello Bruce, I was at Meadowbank from 1988 to 2000. They had evening classes at which you could use all of the machines provided you completed the occasional F & M module. There were various modules and provided you completed 23 you attained a Certificate 3 in Engineering. It took me 12 years and lots of my own work. I worked nearby and did not have a workshop at home at this time.
To get back on the topic, the Meadowbank workshop floor was a suspended wood floor at your time and this was probably the cause of the problem with the train vibrations being transmitted to your work on the grinder. In about '95? they put in a concrete floor which was benifical to all of the machines.
They were good times.

Thanks for the reply.
Yes, I do remember It was a wooden floor.
There were also a whole lot of very old, well worn, probably out of WW1 or maybe WW2 lathes.
The store in the workshop had horrible hand forged carbon steel tool bits for the lathes.
Our teacher said it would be best if we begged, borrowed or otherwise obtained decent high speed toolbits from our works or wherever, to get through the course, otherwise we would find it very difficult !
I followed that suggestion. We had a vice screw to make as an exercise, it had to have a square thread screwcut into it after machining to size.The thread had to fit a gauge.
Anyway there was one only, nice new bench mounted Hercus Model A lathe which I was fortunate enough to use.After that screwcutting job I was hooked on Hercus & have been ever since.
Yes, I agree with you, thay were very good times.
I just wonder if there is still equipment like we are talking about at the Meadowbank Tech
Maybe I should take a visit & check it out.
Thanks again for your feedback.

Bruce,
I was at M/T doing F/M 59-61. I was apprenticed at the Gasworks Mortlake.

Our fitting & machining theory teacher was Mr Martin.
I cannot remember the name of the F & M practical teacher but he was a good bloke with a lot of knowledge.
I also rember the Gasworks Mortlake, I had another apprentice friend who lived in Archer st Concord.I lived in Burwood & was apprenticed at AWA Ashfield.
Some of the best years of my life, fantastic times.
