    Great job. As you say the price of cutter is not worth calculating in the price of the pieces.

    One question: How do you fix that brass/copper?/ to the plate?
    project 1 , 2, Dust Shoe ...

  2. Ta Dean,
    I have ordered some to try.

    It takes all sorts to make a world, I am just glad I am not one of them.

    They are pressed into the holes mate I made the holes .1 under size, carbons pretty soft so needed a tighter fit.
    If it was alloy 0.02 would be enough.

    Don't waste your time trying any others mate I got some coated ones of the same style and not worth the extra money, I've only tried them on carbon, plastic and MDF.



    1 cutter did all this that's all the holes and profiling but finished the profile with an end mill, I have another program that does 20 parts per plate just the smaller rectangle parts but the cutter was worn at the tip and makes the edge tapper.

    eBay item number 221965675192 don't let the Chinese put you off they came in around 6-8 days, and I'd bought 1 cutter from the UK and snapped in 55 seconds using the same speeds and feeds.

    I've tended to use diamond burrs, the type you find in rotary tool sets, for cutting carbon. Even less than 55p each! Here's a recent example:

    I'm still using that keyring - amazed that I've not lost it yet. I'll splash out on the cutters suggested here for the next part and compare...

    Deffo splash out Jonathan that carbon looks really chewed up :(

    This ones not been deburred or anything yet, but as said just a quick rub round the edge with wet and dry and it's burr free :)

    It's just the edges, which as you've noted, clean up well with sanding. I agree it's not ideal.

    Still, for some things the finish is a little hard to discern in when the part is in use ;)

    Well I'm sure you'll see a big improvement with the corn cutters mate, but minimal clean up for me is a big deal and only a few need clean up the first few parts come off needing nothing but a wash.

    But when selling parts if they don't look 100% spot on then and rightly so people complain.

    Good post! Thanks...

    how did you hold the carbon sheet? Screw and glue?

    cheers, Billy
