    Default TAFE project die holder

    Just a simple die holder I made at TAFE a couple of years ago. The body was profiled on a hydraulic copy lathe (because apparently it's still the 70s and CNC hasn't quite taken off yet ) and the handles attach by M12 thread. I sent it out for a black oxide finish with a job at work.

    The drawing was for 1 1/2" dies, but there was enough material to make it double sided with 2mm in between, so I figured I'd go 1" as well.

    Quite pleased with how well my knurl came out; should have given it a light file though, it's almost too sharp

    Unfortunately not, but I can take some measurements and draw it up

    That's a pretty nice die holder. All i made at TAFE was a vice that's only good for a bar ornament.

    Its a shame that TAFE is so backwards, They don't teach skills that are relevant and up to date, makes it hard for employers as we pretty much do all the training and the appys just go to TAFE to tick the boxes.

    Nice job Elan.

    I work in the Engineering Department of a TAFE college and am really disappointed in how the whole curriculum ( theory and practical) has been "Dumbed Down" to a point where even Apprentices at third year level only work on projects that I would consider to be first year or entry level.

    I have been thinking of starting a thread on projects done at TAFE, I hope it hasn't been done before, where we can show some of the interesting things made over the years.I will have to gather all of my projects together and get some pictures posted.

    Yep, the curriculum is pretty abysmal. That was a second year project, along with a V-block and angle gauge.

    Basic metrology is basically untouched; if you can read a vernier and micrometer, you're all set. Sine bar work is touched on for the angle gauge with a bar that's so worn out it has flats on the cylinders (I found a good one out the back so I used that instead). The use of a height master is now covered in the Cert IV course because I, as a 2nd year student, showed one of the teachers how to use it, ditto for the hardness tester. There must have been 10s if not 100s of thousands of dollars worth of top quality metrology equipment in the store room (Mitutoyo toolmakers microscope, Zeiss dial comparators, at least 4 autocollimators, thread pitch tester along with other stuff I couldn't even guess at the function of) and no one even knows how to use it, let alone teach it

    Thanks for posting those drawings. Given I'm clueless, would you be able to give an idea of the stock you'd start with and very rough summary of the order of operations?

    Just for the middle bit - the handles look straightforward enough.

    Rough stock for the body was 150 x 60 x 25 (extra length to have something to hold in the copy lathe or CNC, it will not be easy to turn the profile manually).

    Order of ops (if i remember correctly) was:

    Layout profile on face and ends (do not centre the layout horizontally, leave 1-2mm on one end to face off, the rest is turned to a spigot for chucking later)
    Bandsaw/mill excess stock off about 3mm away from marked lines
    Set in 4-jaw, face off and centre drill short end (this will be used both for a live centre and to drill for the handle)
    Flip and turn 25-30mm long spigot for chucking in copy lathe
    Copy lathe for profile
    Bandsaw off spigot
    Face to length, drill/tap for handles
    Set in 4-jaw to drill/bore for dies and face to thickness
    Hold off inside of die bores to drill/tap for set screws with indexing head

    The handles do look straightforward, but just in case...do the knurl FIRST with a live centre, then face it off. Make a plastic/aluminium split sleeve to chuck the knurled end afterwards.

    I could see that centre profile easily done with a simple ball turning attachment for your lathe, would be nice but we don't all need CNC.

    Hi Dave, Guys,

    That thought crossed my mind as well !

    I do like the double sided idea, particularly since I have some 5/8" inch dies and no die handle. Missing in action since one of the 5/8" dies from the set is missing as well. They are also not round having multiple scalloped sides.
    Best Regards:
    Baron J.

    I ordered a my LH die from AliExpress but it didn't say the outside diameter, I wasn't happy having to make a holder for a smaller than usual die just for it to do the job.
    I didn't realise they made them that small.
