  • Mill/surface grinder will this work??? Alistair

    I use a surface grinder at our local retired engineers club at the college.I find it very good but every time I think of the expense of buying one and the amount of times I would use it I shudder at the thought.I Have however a nice little eight by four inch magnetic chuck and my mill has feed on the table it is also fitted with variable speed with an invertor .Could I rig up an abrasive wheel with a guard to fit in my horizontal spindle to use this for light surface grinding and if not why not I cannot see why this is not done regularly but obviously there must be a reason just can'tsee why??Alistair

    Grinding is Dirty for one, I bet you dont have the speed in your mill for another. Noe I have heard of guys useing a radial arm saw with a grinding wheel on it,If its set up correctly and you are careful, it may work.

      There's a chap called Dave Baker who frequents uk.rec.models.engineering who I think does something like this. You could try asking the question there.

        I once had to clean some dovetail slides up that were cut to 70 degrees and I only had a mill drill at the time.
        I used a 4" cup wheel on an arbor and dressed it with a valve seat dresser to 70 degrees the ran flat out at about 2,000 revs and just kept taking a small lick off.

        It creates a hell of a mess and even though a wrapped the machine well i had to take the table off and give it a good clean down.

        Got me out of the kackieoppy but not really to be recommended.

          A lesson in life. About 10 years ago we needed to broach a keyway in a casing on site. We made a shaper out of a master mill feed table. It worked great and got the job done. The problem was we wore out the table after the second keyway. The cast iron slide and table just couldn't hold up to the constant stroking, even with liberal amounts of oil. We probably stroked it a several hundred times in a few hours. That would be my concern with your machine. You would be basically running rapid traverse, constantly during the course of grinding and I am concerned you would wind up wiping out your ways not to mention the wear and tear on your spindle.

            I would suggest to go ahead and get a good surface grinder if one comes available. You will be surprised how much you will use one if you have it. And hopefully you will have room to build a room around it and your other grinders.

              Just in time: New HSM has cover photo apparently referenced to a DIY surface grinder project. Alistair could knock if off in a weekend if he can tear himself away from the chest of drawers. Haven't cracked the cover yet of either the HSM or the MEW that both arrived yesterday but the MEW has motorcycle porn on the cover referenced to an article on chain drives. Would think they would find a Triumph somewhere instead of a geriatric Honda.

                you could use a small tool post grinder in a shaper to make a surface grinder. saw that in a book some place.

                  Alistair, I know where there is a small surface grinder available down here in East Anglia for about آ£250. It's at one of my Toolmakers on the east coast.

                  It's a Dronsfield Eagle No.3, 18"x6" travel, manual traverse/feed. I have an Eagle no.2 and its a very useful small grinder.

                  If you're interested I'll mail you the contact details for him.
