Hi all,

I just joined HMEM . I am looking for drawings for a tool and cutter grinder. I am an experienced machinist with a home shop.

Are looking to sharpen tool bits or milling cutters?

There is a wealth of knowledge- some good some not so good of contributors on this long and complicated topic. It should be accessed as a guid to your own needs.
Amongst the questions which those who have ACTUALLY built tool and cutter grinders about your needs, your wealth as inevitably you must have equipment to build one, your ability or inability to buy or get plans and so on and finally, whether you will be able actually use one.
So many, many questions and so many answers that you must provide.
I'd welcome your information and be pleased to add my limited experiences

Best Wishes

Norman

As an Addendum or whatever, I have a hand which is locking up and both gardening and maching are out until things improve.
Another disable person invented an unusual tool and cutter grinder some years back. I had the basic drawings and castings but never pursued iy because I built the Quorn instead.
Sunsequently, the design went to a Gu in scope and y Lautard.com in Canada, was greatly extended I've followed the building instructions which can be fabricated or , now, the castings are available again.

So I suggest that a look at the Guy Lautard Tinker site to see if this might suit your purpose.
According to one builder, the BASIC kit can be made in a week but your guess is as good as mine.
The price of the plans is fairly cheap and I'd be pleased to have your comments to read.

Hi Guys,

A few years ago I started collecting metal stock to make the fabricated version of the "Tinker" TCG, I never actually started any machining. I've still got the metal kicking about in a box somewhere.

I got distracted by other things :) I'm currently making a much modified "Brooks" TCG

Thanks for all the quick replies everyone. I am looking at grinding mostly milling cutters. I really like the Quorn too. I am hoping to find plans for something similar. I will look up the suggestions you made.

If you are only:)mad:) wanting to do the ends of milling cutters there are numerous alternatives. The Quorn itself has lots more facilities and will take up a lot of time and take you into the realms of 'making othher complicated tools. Again the kit is EXPENSIVE.
I have an old Mark 1 and itIS difficult to set up. The cheaper but probably just as time consuming is the Bonelle which has free plans and can be made without castings. I Haven't made one :cool:
As John( BaronJ) has demonstrated, he has a much modified 'Brooks' which is a much modified Stent which originates from the once hugely expensive Clarksons. The Stent is from Blackgates Engineering in the UK as plans and castings but can be fabricated. I have an example and very good it is.
The Derek Brooks comes from No's 16 and 17 of Model Engineer's Workshop and lacks the ability to swing the table top but is made from bar metal and an old felt hat(?) to exclude dust which is the bugbear of most grinders.
I'm going to dodge both the Harold Hall book and Chaddock's Quorn book. I've written enough and you can read them for yourself. Both are excellent and are recommended.
To tackle little more than doing up lathe tools and touching up ends of mills, the Australian Eccentric Engineering Acute tool grinder can come as a kit and it can be inexpensive from - arguably- the scrap box, There are videos to see what it is all about. The plans are about £20 or so in the UK and well detailed to follow but you MAY have to consider adding templates and an ER Collet
The lost is NOT exhaustive but exhausting and I am indebted to John Baron and many other contributors for ----A LOT of HELP-- and good humour
Hope this all helps-- a BIT

Hi Guys,

Just a quick note about a swiveling table ! No Brooks didn't include one, but I did. If you look at the picture I posted, bottom right hand side, you can see the collet holder which is adjustable for angle, mounted on a plate that swivels +- 15 degrees. It is mounted on a very long "T" nut and secured by two M6 cap screws.

I have just recently completed the Bonelle T&C grinder which according to it's designer is an updated version of the Quorn. (Don't flame the messenger ;-) )
It has the benefit of being designed for machining from bar stock, ie no castings required. It is in most aspects virtually identical to the quorn and the quorn manual can be used for setting the grinder for various tools. It took me about 4 months of spare time to complete and I am very happy with the results.
The plans are available from various sources but I recommend you join the Quorn owners group and download the latest drawings of the Bonelle from that site as they contain the latest edits including documentation from the designer. I made the mistake of following a set of "metric equivalent" drawings initially which were found to be full of errors.

Following up BaronJ's excellent discourse on the Brooks grinder, Derek Brooks only designed in TWO dimensions and seems to have locked in the 3rd dimension with a WELD. Of coursr Professor Chaddock not only allowed the grinding head to go up and down but allowed the whole thing to rotate- albeit to lock the movement. An old friend- sadly long gone- created a fabricated one but could mechanically alter the height of cut' grind. Of course there is no reason why the Brooks could be similarly improved.
After all, Brooks literally added the tool holder of the Quorn into his 'simplified' design. getting heady?
So the magic bit of mathematics comes into the various designs but the designers add the facility but avoid the necessary explanation. It is fairly simple and I have explained it before but here w? Go up and give the teacher a loving hug:)
Laughing, it all is a vertical slide or if you want another variation, a moveable one. late
So im my pedantic way, I have bought a rather strange vertical slide( which Can be tilted and rotated and can be graduated from a division plate. It's rather more but enough for the day

Cheers

Of course someone will claim that the Bonelle- excellent though it is- is eclipsed by the Mark3 Quorn.
I bought the drawings from Hemingwaykits and not only are additional graduations - for more precision but the ability to hold drill bits more acurately with the added ER32 collet chuck. So whatever next?
Well the mystical art of rounding off cutter corners is simplified from - rubbing two sticks together- or sort of like that.
Of course the plans and instructions are relatively expensive and the cost of the kit which does not include the collets etc is- in my opinion rather hight.

I tried to get a 'conversion kit' to raise my feeble efforts in the Mark1 to the Mark 3 but without success.

There you have it== sorry about the long winded contribution

I built Guy Lautard's "Tinker" grinder from bar stock. I am happy with the results, and accessories included in the drawings allow grinding of many things other than just end mills. The plans are thorough, and all parts have recommended machining procedures. There is also an extensive "how to" for set-up and use of the tool for various operations.

Good luck.

I went through the 'later' drawings and this is why I made the suggestion.

Thank you-- and Best Wishes

Hi Moose,

I have been trying to get on the Quorn owners group. I am experiencing trouble with their e-mailing system. Is there another way to get the drawings for the Bonelle? By the way, your grinder looks awesome.

Google J.D.Willis- Bonelle tool and cutter grinder for a lot more on settings constructions and use

Thanks John, the drsawings I have but could not find them on the 'net


The late John Stephenson had it on his tool ans cutter CD-- alas both are no more

There is also a Mini Bonelle=======I have it but where?
