    Hi Lee

    If you look at the second to last pic you will see I solved it by milling counterbores into the rack, I was going to put button heads in it but decided to counter bore instead

    Had some more spare time today so I hacked a torch mount out of a chunk of solid Aluminium, It made me realise that I will have to make a 300mm dropper plate, any how heres the pics



    and just to show the torch fits I tried that in as well

    Hi Lee

    Im starting to get real fed up with tapping holes though, that seems to take for ever by hand, I could use the drill but I dont like doing that.

    not quite.... I bought the wrong nut from Merchant Dice, I machined it down to 20mm od and cut the top hat part off so it was just a round bit about 25mm long with a thread down the middle, then I bored the ali block on the miller to fit........nearly

    have got a piece of ally on its way from ebay 100mm wide, 10mm thick and 300mm long, 10 not bad.

    need 2 more steppers but they will have to wait a week or so, "ER" is starting to moan

    Send me a link to your rockcliff please,

    Hi All

    decision made!! There is no going back now "Z" finished apart from a small second floating "Z" to get hight, I have drilled and tapped botom of "Dropper" plate to take a tool holder so I can use table as a router as well by sliding second "Z" up and bolting tool holder on.

    Just a quick update, finished floating "Z" ready for THC, Luckily Jim Cullins from soundlogicus.com will still ship one to England along with a breakout board from Rob Cambell will make a good combination, I hope.

    A floating z axis, so you're going to use the 3 ball arrangement to set the torch height. It does sound heaps easier than faffing about measuring the volts. This could be up and running PDQ.

    Looking good. We'll need a movie when you get it cutting :D

    Hi Robin

    actualy no Im not going down that balls route, the idea is to put a limit switch on floating "Z" and use as a ref, bring "Z" down torch will touch metal and lift floating "Z" into ref switch, and stop then lift "Z" by a known amount (switch travel + clearance of tip) and fire, this way every start will be automaticly set to differing thicknesses of material, as the distance of lift will be a constant. well thats the plan, Mach3 has this ability
