    Thought I would make a first post on the Tool and cutter grinder build. As I cannot afford a Clarkson tool and cutter grinder I have been eyeing up this type

    but wow they make lots of money for what is basically a grinder, with more accuracy.
    This is the base idea I am hoping to put together,

    once I have this part sorted I will then sort out the swively parts, as per normal there is no planning apart from a bit of a sketch while having a cuppa.
    Father had to got near the scrap recycling yard today so I went with him and manage to grab some steal plate the straightest I could find was some 20mm thick plate,

    will need a bit of chopping about to get the size and shape I have in mind. I also picked up some round bar but it only 22mm and I have got the boring bar stuff

    although its a bit thick and to wasteful to turn it down to about 25mm.
    I did find an old motor that is face fitting but it is only 1605rpm,

    will this be a bit slow or do you think it will do, The ones I have seen on the net are 3000rpm and up. I am hoping to fix the grind wheel directly to the shaft so will be direct drive as I don't think I will have space for pulleys and belts

    The Chinese clone is actually of the GHA grinder which was a clone of the Decal (German I think). These are single lip tool grinders where as the Clarkson is the daddy and is a true tool cutter grinder.


    Jord I think your motor will be too slow as like you say they run at around 3000rpm. The motor on mine is 1425 but then drives the stone via a 2:1 ratio pulley so making it around the mentioned 3000rpm.

    If you need any more photos just shout.

    Cheers Fazerruss the photo's will be handy for later when making the tool holders I actually got my inspiration from the Deckel ones your George Alexander one looks good, they hold there money well, I have watched a couple of them
    What collets have you in yours are they Er32 or 16 I am thinking pushing the size up to ER40 to sharpen bigger stuff.

    Thinking on it the motor would need to be bigger:thumbup:

    Cheers :thumbup:I had forgot about the quorn one I first saw this type ages ago then lost it I really like the way the swivels are set out I may got this route with the 2 slides as then I could possibly use the pulley type off the motor increasing the speed

    They are ER32 collets in a modified chuck. The machine only came with one original collet and they are ridiculously expensive. There were 2 types, one relatively cheap and the other exactly the same as the Decal. Mine turned out to be the latter so I upgraded.
    You shouldn't need a powerful motor as you only take a very light skim to sharpen end mills ect. Mine is only about 1/3 hp

    I actually have, thanks to @gaz1 for the heads-up a good while back :hug:, a Quorn packed in three boxes in the cave - I'm resisting even unpacking them because I just know I'd launch into refur'b/rebuilding it. The only thing I've done is check the motor which came does it's whirly thing, and it does :thumbup: . The other boxes remain taped up - I've surprised even myself with this exhibition of self control, never heed my pals. :D It's had to take its place on the list until it can receive my undivided attention, preferably when the weather's a bit better. :laughing:

    I'll slowly getting there.....:D

    I have not had much time on this this week, blasted works got in the way :( I have changed my mind on the Deckel type and decided on a Quorn type cutter grinder as for what research I have done it will give me more options. Its not a lot but I have managed to chomp out some more forklift tine

    The upright bar is the 1,1/4 boring bar and I found an old stainless boat shaft 25mm which should do the cross bars.

    Not a lot but a start at getting the base worked out.

    Just a quickie done a little bit more in the week I couldn't do the spiral column as on the on the qourn, so have threaded the block and use some threaded bar hopefully it will lift and lower the motor and cutter spindle.
