    You can now buy metallic layered perspex that when engraved shows the rear colour thru. You can also get reverse laminate where the front stays clean and you engrave in reverse on the back then fill in with paint, so you get all the engraving on the back and a clear front so it can't mark or rub off.






    These were done with a laser but no reason why they could not have been done with a CNC router, in fact that's all i had until I got the laser.

    you need a Parallel Port/printer port (old computer that has one or add a pci Parallel Port card to your pc if its not got one)

    if your dad gets to use it you can twist his arm to cough up for some tooling :)
    (ebay/china)pack of 3.175mm carbide single flutes and a couple of 6mm carbide single flute cutters will see you through most general machining adventures
    Thanks for the info mark that’s good news I do have an old PC and I can put the PCI card in it. My plan is to let my Dad loose on it (I’ve found him a video tutorial package on Auto-Cad) and he can do his own projects and of course buy the tooling for it :) I'm going to have to look into cutting methods as I want to cut out shapes in the case and then back fill them with resins, but there will need to be an undercut or grove so the cured resin won’t fall out lol ... I have all sorts of ideas running through my mind at the moment.. Except the one where I explain to my accountant what I spent nearly £800 on and why I spent it, and how that’s somehow related to IT.. Another bridge.. lol I’m even considering glass , but for sound instruments glass has a problem with resonance, but I will at least attempt to make one. Also one of the reasons I want to skill up on the CNC is to make PCB’s because I’m thinking of exotic shapes for the enclosures and I could.. Hopefully re-engineer the PCB to fit that idea.

    im guessing that plate has been etched, mayber with a lazor?
    it would take quite a bit of effort to machine it with the diffrent size/thickness of fonts

    if you tacticaly designed a line drawing decal you could easily drag engrave your plates add a touch of paint then burnish it clean?
    a simple spring loaded drag engraver it pretty easy to make if you can get to a lathe?

    Seems Like a lot of work Mark .. I think Irving’s idea of printable decals could be more my skill level lol I have seen dry decal kits advertised, I’m looking into that..

    Thanks for that , I have a compressor I’ll find a 2nd hand air gun and buy some cutting fluid, and I think decals will be the safest and probably easiest method.

    Printed circuit boards area higher level or at least equal to engraving.
    End of the day it's just practice

    i get 99% of my tooling etc through ebay(china for carbides... you have to patient)

    davis industrial plastics(online) for my plastic stock
    acetal machines really nice and may make half decent molds as you cant bond it without some serious pissing around with posh chemicals (or scorching it with a flame in an emergency....but it will lose its shape really easily and the fumes make your head bang)

    theres a local plastics supplier that i keep meaning to pop into but never get around to :)

    LOL sounds good I'll get some samples from them .. i'll ask my mate about soft metal suppliers in this area .. I also like the sound of this "Corian" looking at it on the tinterweb and it can do alot of different things ..:) and I just found a supplier not to far away in preston .. http://www.solidsurfaces-northwest.co.uk/materials
