    Sorry Bryan,

    After I mentioned the stamp I wondered whether it was a universal reward or solely a Education Department of Western Australia thing. I can't recall too many decorating my exercise books.

    Bob.

    Default Just a little progress

    The daily temperature of everything in my shed has been hovering in the low to mid 40 degree range - so not much progress. Every now an then I brave going in there for a little while - sometimes just before bed time (midnight or so) and do a little bit more work.
    I've continued scraping the dovetails of the table - but only close, rather than perfect, because I suspect when the weather cools a little it will all be out anyway. I sometimes have the sense that handling my straight edge/prism, my hands are COOLING it locally and it bends
    I've also made a little progress on the spindle. I decided to turn up a pair of 2-speed v-pulleys - either for an M-section belt or a urethane round section, depending on the vibrations. I've made the motor mount too. I acquired and installed a double row angular contact bearing at the drive end and a floating deep row bearing at the other end. That should work. Both are sealed. Left to do are a pair (or more) of fitting wheel flanges and bushes to suit my collection of T&C grinding wheels.
    I've also ordered a Russian CBN wheel from the Ukraine (Schleifscheibe aus Borazon (CBN) Form 12R4 Ø 125 Körnung 100/80 für zuspitzen | eBay) let's see how that turns out.

    A photos to show some progress of my activities:
    IMAG0178.jpg
    To get there, I had to scrape a flat section on the top of the table - overall it has a bow of around 4 thou, highest in the centre. The flat ways seen blued here had about 2 thou wear in the centre and have been machined by a previous owner. The centre was worn smooth and the ends still had machiniing marks.
    The sloping sides of the dovetail are surprisingly flat and straight, I won't touch them until I have done the top of the saddle. The saddle unfortunately has a slope on the flats of about 50 thou end to end and in relation to the dovetail slopes, so I'll get that ground first then scrape it to correct any error in the dovetails.
    Then, to ensure correct mesh of the rack and pinion, the center section in the photo (where the rack mounts) needs grinding a little deeper and flattening at the same time. It seems to follow the 4 thou bow of the top of the table.... I'll be able to shim it to get as low a backlash as possible without binding in the teeth.
    All in all a great learning excercise and practice at measuring and scraping....
    Cheers,
    Joe

    Hi Joe,
    Watching with interest.
    I did a few rounds of the top table of mine just to get my eye back in. It was pretty good.... unlike the lower table lol.
    I tend to do one cycle and then run inside for awhile
    You have a straight edge that long?
    Arent you using the saddle for spotting? how are you keeping the flat ways parallel?

    What was the postage on that wheel?

    Good to see it coming along Joe

    Seeing your Bunnix/Aldix reminds me that making one is highish on my list.

    I'm lucky in my shed, being insulated it's still 25 at 4 in the arvo....but by 5 it starts getting real hot. I've been trying to scrape early in the day.

    Oh, and my floor is only clean cause i just cleaned it.......

    Hi Stuart,
    I can't use the saddle for spotting yet - its flats are not parallel to its dovetails (50 thou over its 6" or so length!). That is one of the reasons I'm not scraping to any level of final state. I'll do that once the saddle is ground right. I've kept the table flats parallel by measuring only.
    My straight edge/prism is 610mm long and the table is only about 500mm long - a lot smaller model grinder than yours!
    The postage from Ukraine was EU6.- not bad.
    Cheers,
    Joe

    One more thing Stu et al:
    my little C.C. does not have an upper pivoting table. It does have a pivot hole in the table that I have though. I'd like one to grind tapered tools or reamers.
    If anyone has a slice of cast iron 500x100x25 (20"x4"x1") or so, with or without a T-slot, I'd be more than interested! Even something this could be cut out off would be good!
    Cheers,
    Joe

    Hi Joe,
    I'll check the piece i picked up at the tip shop, but i think it is only 18 or 20mm thick. There may be a few holes too over that size, i'll check tomorrow.

    Default Look What Followed Me Home

    Hi All,
    Thought I would show you what followed me home .... A CC Universal Grinder.
    It has the Motorized Head for bolting to the table, this must have been for Cylindrical Grinding, has the Inside Grinding Arm but has been broken off, should be a relative easy fix.
    There is one Collet and some other bits and peices and yes a nice little Magnetic Table.
    How much did it cost me for this lot $0.00.
    I intend to replace the motors or rewire for 240 Delta so I can use some VSD's on them as I only have Single Phase.
    The rebuild of this will be quite a few months away as I am reworking my Mill and Lathe as well as making a new Workbench and Welding Trolley.
    Pictures attached to see what I got.

    I like it Keith, especially the compact pedestal base and the motorised work head. Then there's the mag chuck!

    A nice acquisition.

    You are as lucky a bastard as I am, Keith!
    I'm looking forward to your reto blog on this one!
    A question: I see you have the 'tooth rest' - not sure what the correct term is.
    What does it mount on? I've been puzzling how and where to mount one (that I have yet to make).

    My project is moving on too: I've had to change motors, as the motor I had runs in the wrong direction and has a common internal connection beween start and run windings. I can't get to that point ans it was tucked in before the windings were dipped and baked....
    I had a very similar motor, build the same way, that I could get at and separate the winding ends. I've now incorporated a reversing switch and a main switch into its terminal box and painted it to match today.
    I've also test run it with two grinding wheels attached: runs beautifully quiet and without any vibrations.
    Next is finishing the painting of the grinding head and then finishing the saddle and table.
    Cheers,
    Joe

    Hi Joe
    it depends on what your grinding sometimes its mounted to the wheelhead and some times to the table.
    to sharpen the sides of endmills you bolt it to the wheelhead (i have been doing this tonight and the tooth rest is a right pain to setup in just the right spot)and for milling cutters you bolt it to the table it just depends on what your doing
    Cincinnati no1 and 2 books are a good source of info and can be found for free on the net
    if you want some pics of the mounting hardware for my cinci no2 clone let me know

    P.S nice score keith I like the welding table to

    cheers

    I made a serious start on my Xmas present from PDW.
    Most of the castings are now cleaned up, sanded, chips filled with polyester filler, sanded, spray putty applied, sanded, primed, sanded and gloss epoxy enamel applied.
    All the handwheels, scales and way wipers are polished and the column fine sanded (down to 2000 W&D).
    What's done looks terriffic! I think Bob would approve
    I've got new bearings for the spindle, new felt to cut for the way wipers and started on the motor mount. Spindle housing (complete Z axis really) now on the bench to be started.
    I scraped the ways on the base - they were hardly worn with original scraping still visible, pretty flat and as good as I can measure at right angle to the column - ready to match the saddle and then the underside of the table. Once that's straight and flat, I might enlist RayG or Josh's help to grind the top .
    The last photo shows roughly how the parts fit together (loosly).
    Thanks BOB

    A little more progress to report.
    I completed the finishing and painting of the wheelhead, made and fitted new felt wipers for it, fitted the spindle with its new bearings and pulley, made and painted the motor mounts, painted the motor to match and fitted suitable switches, and fitted a couple of grinding wheels after turning some flanges.
    I also came across a little steel cupboard and a heavy steel sheet pan to fit on top at the tip shop. While I was there, I also acquired a set of ball-bearing shopping trolley wheels to raise the whole thing to my working height and make it mobile. To fit the latter, and lower the centre of gravity as well as give it a wider stance, I welded some outriggers for the wheels to a heavy 1/2" lump of plate I had in the useful box and mounted the cupboard on top of that. It all feels very sturdy now.
    I'm about 'arf way through making a belt guard and a pair of centres fot the table.
    Next on the list are some shelves for the base, a steel door and grinding and fitting the table.

    Hi Joe,
    Coming along nicely.
    240V single phase motor with ON/OFF FWD/REV?
    Can you flip the motor,spindle and terminal box over so the belt isnt in the way of the clamp? Of will it get in the way of something else?

    Stuart
