  • tool grinder table

    Apart from safety what are the main advantages disadvantages of cutting above centre height.Before you all jump on me what I really mean is sharpening on an eight inch wheel grinder using the table provided and a subsiduary table which would sit above centre height of the wheel.I know if you go too high you can have the wheel throw the tool out towards you just like a saw blade.I have anice grinder which is really very good with two eight inch wheels I have quite a few grinders for tools with tables built in but the one I am asking about only has a little table/rest for your tools and does not or cannot be set to an angle is it in this case feasable to add an extension table which will sit on top of this little rest.Hope this is clear here is a picture.
    Alistair basically the tool rests are too small for my shakey old hands

    I think Id be more worried about cutting below center as this has the potentual to draw the tool into the wheel ----- I think your fairly safe unless your tool has allot of mass and catches then it could impale you

    I will say this --- i wish I had your grinder, its built like a brick #%*@ house...
    Never seen a more solid table/rest than that, very nice ...

      By setting the table at a suitable height above center, you can rest a lathe toolbit on the table and grind any specific angle you want -- at a wheel radius of 4", what is the distance above center you need to get a tanget angle of, say 7 degrees to the vertical, etc.

        yes I have a few different grinders this ones 3 phase .These gryphon motors in my opinion are the very best they go on and on and on, I have seen one used in dentistry for grinding polishing dentures in use every day for 35 years and still works as good as the day it was made.This one of mine is relatively new.Alistair

          I would look at the possibility of taking the guards off the side and grinding on the side of the stone ...if it can take it ...or possible ..

          make your tilting plate on centre, on the side

          grinding cutters on the front of the wheel will gouge a radius out of them....so not ideal.

          other comments welcome

            I made a new table for my Baldor grinder (well, one side, have yet to complete the other side) that I should take a pic of. I think it would be JUST the thing for that grinder. I'll try to take a pic tonight.

            But it's made from 1/2" steel plate (CI would be better, but I had none convenient) and it allows working the front, side, and corners equally. It's also designed to provide a guide for dressing square, and future attachments that may need to traverse square to the wheel (say, for threading tools). I freehand most stuff, so a "quick release" is also in the works. And that will also allow "quick adjust" for setting arbitrary height or angle to the work. Like I said, I think it would be just exactly what you need, and not hard to make...

                Thanks bad dog sounds good to me. Yes as mark said grinding on the side would be better I use this for more heavy duty grinding normally as I have a few others which are deicated and purely designed to cut on the side and come with tables already built in Alistair

                      If I'd have known you were collecting grinders you could have had a big 10" Wadkin free standing one.
                      Took it out a couple of weeks ago and threw it in the skip because it needed a new wheel

                      These big 440 volt grinders are cheaper to buy with a new wheel and then throw it away

                      Put an 8" Wolf on Ebay a while ago £9.99 start bid and that's all it fetched. Got about 4 or 5 of these so I'm just going to drag one out use it until the wheels are gone then Ebay it and get another one out.

                      They are nice grinders though and really do the job.
                      Get a casting and really press on and before you know it you are down to your elbows

                      Just ordered a heavy duty wire wheel today from J&L, £15.00, more than the grinder is worth...............................

                          Mostly they are grabbed from company sales by employee's, taken home and then found out they are 440 volt 3 phase and can't be used at home.

                          Often they give them away or swap them for something of little value.
                          I picked 4 up mounted a big big steel table with two vises because it was too big for the scrap men to take away.
                          I saved the grinders, got two left, gave the vises away and cut the table up for scrap.

                          .
