Hi Jon

Thanks for the welcome .
Right now I am making the low profile clamps as shown buy Randy Richard on Youtube .
He was kind enough to send me the drawings and I have just been changing them a little as my mill has smaller slots than his and wouldnt fit using his dimensions . I am making one with not too much finese just to make sure every thing fits together using my new sizes . If all is well I will then try to make a set of 4 or 8 hopefully with a bit more care and finish than this prototype
