colyer Caseley cutter grinder

[e couttsParticipant @ecoutts]

I have the plans for the Colyer Caseley cutter grinder and is there anybody out there who has built/used this machine. I would appreciate comments as to ease of use, time to set up, general verstility etc. I have read the article in MEW by Alan Hooper but this is mainly about building the machine

That's the one featured in MEW179

Sorry, I have no actual experience to offer; but I did notice one 'feature' that deserves improvement. … As illustrated on the magazine cover image; the choice of belt looks quite inappropriate for the pulley diameters and centre-distance. … I would be inclined to use a Poly-Vee belt in that location; which would wrap better and provide a much more positive drive [to the extent that, assuming that the prototype worked OK, you could probably use a smaller motor].

It's a nice simple design, sort of Quorn-ish derivative, one concern I have with that design is that the bed bars are unsupported at their outer end. a 300mm length of 25mm bar can deflect quite significantly at its extremity, there is little supporting structure at the bar mounting point which could also lead to a source of deflection. A simple support bracket at the outer end of the bars would overcome this.

I wouldn't use a smaller motor, the one quoted in the article is 1/25hp, personally I would use a more powerful motor, based on my experience with the quorn and Worden grinders. Polly vee belt would be a good option but also consider the round greenthane belting as used on most quorn grinders, this works very well in this application and can wrap a smaller pulley much better than a standard vee belt and is relatively cheap and easy to make up to any length required.

Funnily enough, there's one copy of MEW on my desk, and its 179.

If anyone with a CCG would like to write a short guide to it's use, it would make a worthy article for MEW.

Any offers?

Fair comment CB

I was actually thinking [selfishly] of physically smaller, rather than less-powerful. For my requirements I think the design could be made generally more compact, as I would only use it for small tools [and perhaps fine-honing of medium-size].

As an aside; I've just started watching these videos … his MicroTool holder looks useful.

For people like me who are missing 179 from the piles of magazines my album has a picture I took the Taunton show a few years ago. There was also one at the Midlands show this year, but generally not very common it seems.

To run over 19 issues ?

[BazyleParticipant @bazyle]

New album added with 3 photos from Midland show 2014. Sorry don't know which stand or the builder.

First photo is a drill sharpener not a CC but sort of similar topic.

Should be enough info there to build your own version – in less than 19 issues. For operation see the many quorn articles over the years and use your brain.

Thanks, Bazyle … Useful photos

and it looks so much neater without that big ugly motor and belt

There is a rumour that there are more articles out there than completed Quorns…

> big ugly motor

A 1/25hp Parvalux is hardly 'big'., OK it isn't quite palm of your hand but… and I like the retro style!

I bought the plans at the Bristol Exhibition a couple of years ago and decided to make one using mainly steel fabrication. When the warm weather comes, I hope to get back into the shed to complete, mainly screws and graduation marking to do. I agree with CB, the two bars do seem a bit frail and also they are only 5/8" diameter. I fabricated the securing bracket at the "fixed" end so that the rods are held in 1" sockets. I used the design method of securing the pieces together but because it is made of steel it leaves the option to weld if things start falling apart. I intend using an ER collet sprindle to hold the cutters and a spring loaded pin to index.

If the weather gets warmer, I will try to get some photos.

Thank you all for your thoughts on the design.
