Tool grinder

[fra]

Am looking for drawings to build a tool grinder.
What i have found is the Quarn which is great but would like something simpler. I need it mostly to sharpen lathe tools and drills.
I think it would make a great project and prove to be an indispensable addition to the workshop.

I looked at the Quorn, and decided that it was far more complex than I required.

I built the Stent, which works well, does all I need, and makes a superb, if small, surface grinder too.

The Raymac (Issue 76 and onwards for 5 installments) and Brooks (Issue 16/17) designs were featured in MEW. Alternatively, you can get the Kennet design from Model Engineering Services (the same guys that do the Quorn). Then there's the Stent as mentioned by Alan.

Take your pick.

Have a look at Harold Hall's book 'Tool and Cutter Sharpening'. He describes a simple grinding rest which will do all you need.

Or the same author's book "Milling - A Complete Course" (No 35 in the "Workshop Practice Series") for a slightly more complex Grinding Rest.

Then in MEW Issue 142 (the current issue) there's a "Four Facet Drill Grinding Jig" (by the same author) to suit either of the aforementioned grinding rests.

In the previous MEW, Harold explained how to correctly use the cheapish, commercially available drill grinding jig available from Machine Mart, Picador, Hollands & Blair, etc, and there is, also, an article by Jim Whetren, detailing a modification to the cheap jig giving fine feed to the "cut".

Thanks for the help.

try looking at something called the tinker tool and cutter grinder i have been looking for drawings but up till now i can only find a bloke in canada that does them even though the person who designed it comes from this country

Plough Book Sales has one copy of the plans in stock - $65.

I understand that Norman Tinker, the designer of the Tinker TCGs, died quite some time ago, and I am yet to find anyone in the UK who is a successor, claims copyright on his work, or even has a set of his drawings.

The "bloke in Canada" is Guy Lautard (www.lautard.com/tinker-s.htm) who held the North American rights to resell Tinker's work. He currently lists the drawing for the 'Tinker' and 'Mini-Tinker' at Canadian $56.00 incl airmail to non-Canada/US residents, which seems somewhat cheaper than Plough Books. However, he will not accept the easier forms of international payment (i.e. credit card, Paypal, etc), so the price is probably the same once you take into account the cost of payment.

I have been given a set of Lautard's drawings and notes, but find that he has redrawn and re-dimensioned them with imperial dimensions, whereas Tinker's originals were metric. I find Lautard's notes on construction of the Mini-Tinker are cursory and vague, presumably because, as he himself admits, he has never built the Mini-Tinker version.

I would be very interested to hear from anyone who possesses a set of Tinker's original metric drawings and construction notes, or anyone who can supply them, or owns the copyright.
