    A tool holder for the shaper like the one below would be a good first project.
    Or you could go all out and make some chips like the last photos just for fun.lol
    The last photo is taking 2inch depth of cut, lets see a home shop mill do that.

    Obviously I should have looked at the photos before posting the last comment! I envy the time you have your disposal Those tool holders are very sexy.

    Those pictures aren't mine, they are from PM. I have yet to make my holder like that one.

    Brendan why dont you make your M/T 3 now with the compound you have rather than having to wait to make a new one on your shaper.

    Timing issues
    OK so I pull the self act gears off the side of my shaper without marking the timing. I assume the tee slot for feed adjustment should horizontal when the ram is fully forward and the table is about mid way through its vertical travel. Am I right?

    Pipeclay. Brendans compound slide is only 60mm long. So he can't cut an MT3 in one pass.

    That is correct but he can still cut it ,you dont need to be able to cover the full length of taper in one pass.

    I can look on mine tomorrow morning and report back...

    I just found a clip of it working on my HDD and have quickly uploaded it to u tube [ame="http://www.youtube.com/watch?v=IbU0R4-qkSM"]YouTube - shaper[/ame]

    Thanks RC.
    Looks like it should in line with the feed arm not horizontal.
    Be great if you could check for me.

    Started putting parts back on today
    I ran out of floor space to store cleaned parts lol
    So far so good.

    Some pics... clickable thumbnails...

    I actually cannot remember if I ever pulled this part off when I was cleaning it, and if I did the timing may not be right... But if you think about it you want the feed rod to start feeding just after the end of the forward stroke so at the end of the stroke you want the slot to be horizontal...

    Horizontal it is then.
    Mine is BEC|123914/14, does yours have a date RC? I wonder what DEMCO would say if I gave them a call.
    Yours doesnt seem to have an inch button. Has this been a problem at all? Mine has one but making it work with the inverter I have could be a problem.
    I see you've made your own table support, I think I have seen pictures of it somewhere else. I might need to steal your design as the "thing" that came with the machine isn't it.
    Last question What's on the table on yours?
    Thanks

    It looks like a mill table to me, they are good for extending the table for larger jobs and dividing head/rotary table set ups.

    I'd like to know what the procedure is for cutting those radial serrations. I think they're called Hirth couplings? As they are wider at the outer edge, I guess each serration takes at least two cuts, with some sort of off-setting?

    That I couldn't tell you. I had a quick look in Machinery's handbook and it shows them as a clutch and also shows charts for how to divide them on the rotary table to make them. There doesn't seem to be any mention of what their called, though I might have missed it somewhere.
    The book also shows different types, like teeth with 90deg on one side, a combination of large and small spaces between teeth etc.
    By the look of it he is doing it in at least 2 cuts, maybe a 3rd as a clean up? It would not be hard to do on the rotary table, you just need to work out how many teeth you need to divide for, to suit the the size holder your making. As for down feed that is done with the down feed on the tool head of the shaper, which has a graduated collar on it like a lathe.

    If you cut both sides at once and cut deep enough that the top of the "ridge" is sharp, wont tops on the ridges be concave so they will only meet with the matching part on the perimeter?
    If you stop the depth as soon as the inside came to a sharp point, wouldn't it then meet across the entire face?
    No I haven't made either, just trying to visualise it.
    You could tilt the dividing head to allow for it but no idea how much.
    Maybe I am over thinking and under doing again. hehe

    Mine is BEC 120466/157 No idea of DOM but mine is in pretty good order except for the ram scoring... There really is minimal wear in any of the ways or mechanism...

    Demco are out of business, not even the name exists any more.... I rang a number (brisbane number) that I got out of the yellow pages (it is still listed) but got a company by a different name and was told while they historically were distantly related to the original Demco company they had no info on any of the machine tool products Demco sold...

    My shaper was sold by Whitelaw's so Demco was not the sole Australian agent...

    Mine does not have an inching button as it is not needed... It has a clutch...(the bit long lever)

    Yes I made my own support as mine never came with one, nor did it come with a vice.. Instead it can with that big long table you see bolted to it... It is not a milling table bit just a lump of rectangular cast iron with T-Slots in it....

    Also the picture posted previously with the dog clutch type teeth being cut on it is for a planer.. The person who made it has a 6ft planer...

    I guess mine predates yours because my stroke per minute plate as invicta on it, but it has a "made by elliott" plate on the other side. Strange there isnt a date on the motors. Other than the ram mine seems pretty good, although the bevel gears on the Z are a little chewed up from swarf in them.

    lolthat number in the yellow pages is exactly why I thought they were still around, you saved me a phone call

    And just where does one come across a lump of cast that big?
