  • Delta toolmaker grinder project



    I disassembled it to load into the truck.
    Poor thing was reduced to a cut off machine for bolts. Sad ( almost ) end to a nice machine.
    It has the original motor. The machine Serial number is 103-2341
    No cracked parts. It looks like a typical old machine that was not lubed correctly.The cross feed lead screw is worn to the point of being sharp at the crest. The rack for the table is worn to the teeth being rounded.
    The table is very worn. Using a caliper as a depth mike I get thirty to fifty thou of wear. Good thing there is plenty of cast iron left to reestablish the working surfaces.
    I am thinking of milling the surfaces back to parallel, then hand scraping them at work using the granite surface plate as a planar referance.
    Remake worn bushings, clean, paint and rewire.

    Nice find. I'll be curious to see your progress.

      Thanks for saving this Toolmaker grinder!

      I've had a Toolmaker grinder for, at least, the last 25 years.

      Right now, it is down for some rework, but it will grind again!

        How do I trace the serial number to find the date of manufacture?
        Anyone know the pressure angle of the rack?

            Thanks. I was looking at Mcmaster-Carr for a replacement section of gear rack and didn't know what to choose.
            Progress.

              I too have one, however it will be awhile before it gets the attention is deserves.

              The Old Wood Working Machines (OWWM) site has information on Delta-Rockwell serial numbers and some interesting history.

                I've got one of these and have rebuilt the spindle, but have not reassembled the rest of the machine. Rather than spend a lot of money on rack gears, I suggest converting it to a cable drive. It will operate much smoother. An acquaintance did this on another machine and it was night and day difference. I've got the manuals or you can search for them, they are out there. There is also a Yahoo group for this machine that will have a lot of info.

                  For the amount of work you need to do this will certainly be a labor of love!

                  Good news is that the ways are all square and can be ground. That is what I did with mine. The way the whole head rotates about a pivot I do not think it warrants scraping.

                    The rack would be $47.00.
                    I like the idea of cable for the table. The Mitsui I use at work is cable driven and I like the lack of backlash.
                    Sidenote- We moved the whole shop to a new location years ago. After I placed and leveled the Mits I was horrified to find the table travel to be binding. I thought we did some damage in the move.
                    That is how I found the table lock lever that is under the left side of the table. It had been swung half way to the lock position!
                    Swing the lever and we were back to the free float action I was spoiled by.

                      Labor of love, thats for sure.
                      I look at it as a semi finished grinder kit. All the castings needed and some are already finish machined.

                          Glad to hear most of it is there. I had one a few years ago but it was missing some parts. I looked high and low and did not find what I wanted. So I ended up parting in out on Ebay. Judging for the price the parts went for, other must have had the same problem. I did not remember selling the rack but I was unable to locate it in the material pile after a quick search

                            A word of warning. These are an ungainly beast, top heavy and not at all balanced. In other words a real bear to move once assembled. If you need to be moving it round while working on it think of siting it on a skid or building a low centered cart etc for it. Mine is currently bolted down to a mini-skid just big enough to get my pallet jack under.

                              What a coincidence, yesterday I picked up one of those too!
