Yes Stuart, the 0/I rocker switch is forward and reverse. Yes it is a 1/2hp single phase 2880rpm motor.
I could flip the spindle and motor - and actually did, (what I said here was wrong - I checked).
The back of the motor interferes with the clamp if I do it the other way round. Also, the motor fan inlet is then right in the spark path and will evnetually fill the fins up with metal dust....
On the other end of the spindle, it can only to that if I run it in reverse.
Edited because I remembered my reasoning wrong.Cheers,
Joe

C C Tool and Cutter Designer
Hello Joe, I have just been reading the biography of A E Bishop of the variable car steering fame. On page 9 there is a picture of your T C Grinder and the caption says that the grinder was designed by Bishop while he was working for C C Engineering. Happy to supply more if you want to P M me.

Yes, please Phillip!
I imagine others here will be equally interested!
A link to the story or a scan of the relevant pages would be great!Cheers,
Joe

A E Bishop Biography
The book is 'driven by IDEAS' 'The story of Arthur Bishop A great Australian inventor' by Clare Brown. Published by: University of New South Wales Press Ltd. in 2003. ISBN 0 86840 677 5.
The copy I have is on loan from a member of Bishop's broader family and is signed by Bishop on the first page, I don't think it would be right to scan parts to put on the forum.
There is not a lot of info on the machine but a brief summary of the appropriate bits is that this T & C grinder was Bishop's first design of a tool with moving parts, it was designed after 1938 and before he started with S T C as a chemist. Bishop was in his early twenties at this time.
I will send a copy of the picture to Joe in a PM.

I would be interested in reading that book, so I searched it using the ISBN. Seems to be many available copies around. I might buy one.
What I did stumble upon was this obituary from the S.M.H 2006. Its worth a read.
Inventor driven to keep finding a better way - Obituaries - smh.com.au
The company I did my time with in the late 80's / early 90's Zenford Zeigler. They and Bishop engineering had some sort of relationship. We built some of the rack generating machines for Bishop. At that time I think it was to supplement Bishop's production as a lot of there work was export.

I had a quick read of a few pages of the book on Google Books. Really interesting. Went to Amazon and received a shock. They have cranked up their shipping fees - The 24 dollar something second hand copy suddenly lost the remainder of its gloss. I'll look elsewhere. Unfortunately Book Depository is out of stock.
I lifted this from Amazon's site.

More C.C. T&G updates
It lives!
During the week I received PDF copies of a few pages in the history of Arthur Bishop, the T&C grinder designer at C.C. Engineering, courtesy of Metalman. In there was a photo of the original - it looks remarkably like mine. Thank you Phillip!Over the weekend, RayG and Josh extended their hospitality again and ground the table and a couple castings for centres for me.
Much of the time was spent measuring and devising strategies for 'getting it right', as well as fixturing some very awkward shapes.As described earlier, I had scraped a central section of the table top flat after measuring with my means where it could best be supported in the middle of the bow in the entire casting. I then flattened the bottoms of the slide dovetails as parallel and co-planar to that top section as I could by scraping and measuring on my granite surface plate.
Once set up in the surface grinder and blued with marking fluid, the first pass with the wheel showed that my top scraping was very close to flat and in the right spot That also proved that my scraping of the slideways was very close, because that's where the table was supported.
Josh did a great job grinding all relevant surfaces and milling the rack mortice to accommodate the change in dimensions to maintain pinion mesh.
We also corrected a slope of over 10thou (in it's 6 inch length) on the slide surface for the table
Next we fixtured (badly as it turned out later) the two old castings I intend to make centers for the grinder from. The reason this was difficult, is that the only refences available were the bores on the castings. I mounted them both on a very close fitting shaft and then supported the shaft on a V-block and blocked in the castings to prevent them tilting. All good. Famous last words. Anyway, after an hour or more of grinding their bases flat and co-planar with the shaft centre (in line with the shaft), we discovered that the whole lot had moved in the process So we came up with a new scheme and milled a couple of flats on top and two more at right angles on the sides of the castings. That then allowed more definite clamping and an hour or so later success at last!
I then spent a pleasant but sweaty couple of hours on Sunday afternoon scraping the table dovetails and spotting them against the now good saddle.
I couldn't help trial assembling and trying the machine of course, and by 1am this morning had everything adjusted just right and my first little scrap cast iron block surface ground on all sides - ON MY VERY OWN grinder!
Boy does dry grinding cast iron make a mess everywhere! I will definitely have to fit wheel guards and dust extraction (Shop vac). I still haven't fitted the slide felt seals or belt guard yet.
Thanks again Ray and Josh!Cheers,
Joe

Hi Joe,
Well done by all of you.
Hadnt thought about the mess a surface grinder without coolant would me.
Might put mine of wheels if I ever get "around to it" so I can wheel it outside.
That clear coolant must take some getting used to!

Hi Joe,
That's come up well, and really looks the goods.
I enjoyed your visit last Saturday and pleased to see that all the work you and Josh put in is paying divideds.
How did the rack end up for clearance?
Regards
Ray
PS Stuart, love the clear coolant...
