Another good thing it the tool uses old worn out milling cutters as the cutter bit :med: ,, well worth an hour or so to make one . Also a good tool for the shaper . as John (i hate shapers) has just said :thumbup: :lol: :lol: A few ideas :D ,, old catalogue dose not scan to well :doh: Rob Edit .. ye oldie original tool ,, were a forging , not cut from solid as i have done ,,, a forged tool were the grain of the steel follows the bend would be a better job . --- End quote --- As I have been told I am a bit thick, is this a simmilar idea of tool it looks to easy so is it any good thanks Peter --- End quote --- Sorry i forgot to put the link on |

Hi Peter Yes there is nothing new there ,, tangential tool bit holders are as old as tea :med: ,not the same as a swan necked tool holder , very top of the scanned page is one shown ,, comes in a range of sizes , and takes square or round tool steel , The date on the George Adams tool catalogue is 1928 ,,, i have earlier references to both tools . As with most things ,with engineering processes/tooling get forgotten about ,,, then brought back as the latest thing as if has just been invented ::) Rob |

Hi Lads Well this project has been sitting in the draw for a wile :Doh: So today a finished up the division plates . And machined up the bearing blocks . set up for machining the bearing on the lathe faceplate . and they go together something like this :dremel: Cheers Rob |
