Deckel clone U2 Tool and cutter grinder

[goldstar31]

Is there such a thing as a decent manual to show set ups for this machine?

I've tried and tried for hours to find something that isn't a mumbling, incoherent 'thing'

Years ago there was a Chinese one ( I don't understand Chinese) but it seemed logical from decent filming.

Sadly, it's gone now

Norman

P.S. I should add that in my early days,I ran a technical library for a Royal Air Force station.

I just posted the user manual for the Grizzly Deckel SO clone in the downloads section I also have the actual Deckel SO manual but it is too big to attach let me know if you want a copy we can work out a way to possibly email it.

Many thanks, I have just downloaded it for perusal.
oddly, I have just returned from the Eye Dept of the local hospital where they have been trying to do something for what is now my remaining 89 year old eye.
I presented the local optician's prescription but it turned out to be my daughter's receipt for homemade soup. Fits of laughter all round and ice was broken.
I came away with a beautiful powered eyeglass - for free.
Must be my Birthday. Strangely, it is tomorrow.

Now to try see the drawings- so Many thanks

Norman

I've now also copied the Deckel SO manual- for which I thank you.

I think that it is a question of making the odd single lipped cutter until I become more familiar with the machine as it was originally intended before embarking on other pursuits.

If it all works out, I can then get rid of my other grinding machines

I think there was a dedicated group on Yahoo Groups? with lots of documentation & rebuilds & maintenance topics. Not even sure if YG is a thing anymore. Some groups have offloaded onto new dedicated forums, some have just fizzed which is too bad.

Thanks. Actually i'm a member of the Yahoo Quorn Group which is still in existence. I have a Quorn which some claim the Professor Dennis Chaddock took his design. I can't argue! The Quorn is also a very complicated machine. I was writing to see if someone knew where there was a basic set of instructions- devoid of coughs, splutters, hairy arms
and usually inarticulate description in what becomes a difficult thing to follow.
I'm partially sighted, almost deaf and perhaps intolerant too!

However, I can happily follow the Old Masters in their write ups in the past.

The views are mine, others may disagree but there is considerable evidence that many others experience similar problems to those which I have mentioned.

So I thank those you have attempted to bring simple working instructions to others.

Regards

Norman

I've now found a series of technical articles by the South California website and a manual by by a firm called 'Tool maker'.

However, still no information on who to mechanically grind a lathe tool chip breaker on the Deckel clone

 

[retailer]

I was going to mention the youtube videos by Stefan Gotteswinter but I see someone has beaten me to it. His videos are worth watching as he always explains how and why.

I have just a few months ago completed a Quorn to the point where it is useable, the castings lay in a box under my bench for the best part of 25yrs before I got around to the build, the last major thing to do is the endmill flute grinding setup, however I plan to give Prof. Chaddock's design a miss and go straight to an air spindle, others seem to say that his design is ok and works but an air spindle is a bit of a quantum leap ahead. I haven't tried to grind lathe tools on it yet but will probably need to for my current IC engine project.

i think it's interesting that the Grizzly manual does not show any of the steps for actually making all of the various single lip cutters it is capable of making. perhaps that's why the Deckel manual is so large.

Whilst it is true that adding the benefits of an air spindle is excellent, the tested and tried 'Chaddock' Quorn works OK. If history means anything, the machine was built on a very old Drummond which was older than the so called present Myford 7's. I think that friend Hopper has one! Whatever, the original Quorn was built without a milling machine.
Chaddock built an original Dore Westbury from part machined castings and went on to use the Quorn to build a Vee engine which remains the property of the Society of Model and Experimental Engineers in England and Chaddock made his own 1/10" diameter cutters on his machine. It is claimed that he couldn't re-sharpen them on made!
One of my late friends made one from fabricating but he built in a mechanical lift and utilised 3 systems of pulleys to change the spindle speeds. Chaddock had one and a knocked up pulley of plywood.

Again, this was all before the advent of diamond wheels and diamont pastes. With somewhat flagging memory, Model Engineer carried a series of further improvements and I seemed to upset the then Quorn forum by introducing such heresy!

Perhaps, I went too far. I said that Arnold Throp who was associated with the supplier of castings etc was using a Kennet tool and cutter grinder in preference to the Quorn. Of course, I have both and a rather odd 'short' version of the Stent which sone soul fabricated prior to his demise. I bought it for £100 with the foolish belief that I was only really buying the 1/6th HP 2880 rpm motor! For another £100 I came home with a MK1 Clarkson on one of my forays. I got a bonus of an electric chuck as we were both Freemasons!

So my thoughts are that Model Engineer's Workshop issues 16 and 17 have a Brooks T&C which is a diminutive Clarkson but has the Quorn tool holder as its principal holder.
Read about it in GadgetBuilder.com- and Yes I have the Brooks articles!
So perhaps, I have whetted your interest too

Marvin,

I hadn't your comments prior to my typing up for posting

I've got a U2. I use it to sharpen the ends of end mills (and slot drills). It's a bit limited in terms of collet size, but it works well enough. I find when I acquire a really noshed cutter, that it's easier to cut the end off with a cutting disk in an angle grinder, and to do all the basic shaping and relief at the back and front of the teeth with the same, or perhaps with a skinny disk in a Dremel for little ones - all freehand. Then the U2 is just needed to get all the cutting teeth at the same height and angle.

Having used it for a bit, I'm part-way through making something to go on the lathe to do the same job but which will hold big cutters too - I have a few. I think a bunch of tin foil will keep the grit out of places it shouldn't be, for my purposes. If this ends up working I'll sell the U2 on.

So grit is the problem and this goes for lots including the Quorn.

Probably the best( my opinion) is the Clarkson/Stent/Brooks arrangement with a flat table and easier to dust.

Thank you for your input

Hi Norman,

I trust that you are keeping well.

Yes grit and other very fine particles are a major problem for any machinery that has contacting sliding surfaces. I've seen way wipers made from all sorts of material, from cardboard, felt, rubber and even leather. Simply covering the ways helps but its not always easy to keep or clean the stuff out.

FWIW I'm in the process of building a modified Brooks TCG.

Hi John

I also send greetings and hope that you are well. I'm enjoying my 89th Birthday today!

As you are making a Derek Brooks, there is a bit of a daft traverse arrangement and I have a spare Stent rack and pinion- just doing the square root of not a lot.
Actually, it's 20DP Myford pattern- probably from an old lathe.

I also have the drawings for a Kennet- As I said, it's a lot easier than a Quorn but could be fabricated. Mine is the 'Long wheel Base' variety. Here is the simplest version of the spindles for Quorn, Stent and Kennet alternatives.

There was a set of machined Stent castings and drawings for Buy it Now £60- also with the rack. Come to think of it, it is actually cleverer than than the bigger Clarkson.( Sold??????)

Keep in touch

Norman

Many Happy Returns Norman

Actually I've got in mind to use a length of fine chain and a cog wheel to drive the top slide, my other Idea was a steel bowden cable around a spindle, a bit like the tuning drive arrangement on old radios. I've already made the saddle and baseplate.

Keep in touch

Norman

Yes I will, you take care now.

Thank you for your good wishes but the Brooks is a development of the Stent wich is the devopment of the Clarkson and the Brooks gets the the Quorn tool holder and the Brooks( in original form) doesn't have the movable top table with- of course, Myford slots. Your tooling, I recall, is Myford.

So moving on to the Stent, one of my even older mates( seriously) milled a Myford yee slot along the from edge of the Stent to take precise stops.

Think seriously about the 'spare Myford rack and pinion' offer. It's probably worth your while to sweetheart Blackgates Engineering for the 9 sheets of the Stent when considering the wonderful extra facilities of the Stent over the original much bigger Clarkson. Again, with the Stent you can copy the vertical height adjustment and its ability to move in a rotary fashion. Again, you could add a Quorn rotary table onto the table top of the Brooks.

Nothing wrong with any of them but this is what was done-- and you risk being banned.
Oh, joy unconfined!!!!

Thinking Quorn -wise and the THREE alternative spindles, one can re- pulley the thing with 3 different pulleys. It's been done!


It's not quite 'in the book' but worth realising just how MORE capable these beasties can be usefully altered.

Happy Father's and Grandfather's Day to all.

Excuse me quoting myself, and digging up an old thread - but I recently looked again at using the U2 (/Deckel / Alexander / GHA) grinder to sharpen big end mills. Mine takes R8 collets, and I was pleased to discover that 1" R8 collets exist - the thing is extended beyond the closing taper and the whole part of the work supported, is held in this extension (7/8" is the largest size for a 'proper' R8 collet which can be accommodated inside the taper).

I reckon this would be a disaster for holding a big cutter in a Bridgeport (we use an R8 - ER40 chuck for that job, which works OK) but for accurately positioning a big cutter in a grinder where forces are very small, I think it might have potential. I'll let you know when it arrives, whether it's a goer!

I have to confess that over the last couple of months that I have been going back to 'Firsdst Principles' in taking a visit to see the trains of the Stone Age in a visit to the Hebrides to see the stone circles and the restored so called Nordic and not 'Scottish dwellings. You know the sort of thing of more recent times of 'Donald where's your trousers' and Donald MacDonald of present diet
Then I've 'done' the 500 odd miles of the Scottish NorthWest Passage and ending up-- sort of on the island of Orkney- with more 4 or 5 THOUSAND years of history. Plus a bit of Scapa Flow and with a German submarine sneaking in to sink a British battleship. Great stuff which claims to be the start of the Battle of Britain.Too much to take in for an aged old brain
So in a month' or so, to the placated valleys and terminal and medial moraine of the Ice Age!
Reindeers and almost tundra and merging into oblivion- my late wife';s ashes.
Oddly, her family had interests in going machinery and she in the attrition of-------------TEETH.
At 12 or 13m I used to sit with a Bronzw Age skeleton who was interesting but didn't say much
My late wife used to keep a female head from some desert place and it spent its quiet life in a Jacob's Cream Cracker box.

Well, there wasn't time to follow the 3 degree West line-------------where the gold is. Oh, yes-----that yellow stuff.
Goldstar 31 is quite another story

This good for grinding milling cutters. I am doing the work any more. It up for sale 50% of new. It like new condition.
