    GRP4 wheels back to standard?

    Grp4 wheel back to std ?

    Hi folks, im just wondering does anyone know of anywhere that does inserts for converting wheels from grp4 back to standard?

    I bought 3 mint two gates wheels the weekend I have been looking for for quite a while but they are grp4, however my other 6 are not, and I don’t fancy converting them all to grp4 and buying grp4 studs @ about 7 quid each, nuts and 6 inserts.

    I have a lathe, and I set about making one insert grp4 fitting with a standard hole, and it worked out perfect but the time it took me to do it on a small manual myford I cant and don’t have the time to sit there making 12 of them! It would take me about a week!

    So, is it a thing? Can you get grp4 to standard?

    Thanks!

    I'm currently doing this on a revolution wheel
    Look like i will have to drill the wheel out larger first though
    I can make you the inserts up on a cnc if you send me a drawing

    Ive already made inserts for mine just waiting on a chance of one of the mills being free

    I believe grp4 fabrications in galway do what youre looking for. if they dont have exactly what you need what they do have might be a good starting point to modify them on your lathe.
