Re: [taigtools] Re: Adding extra Z height ?
- Hi Tony
Thanks! Sparked on another new project to improve my mill z axis :)
Will be getting a steel plate 15mm thick by 2" width, mill a step at
the aluminium column, bolt the plate and bolt the mill bed as
well...this will add up to another 2" higher.

- Turns out I've got a drawer full of that style cutters, and a a couple different size fly cutters, but I'm going to have to a tool holder for the for the old style head. All of mine have 1/2" or 3/4" shanks.
The V blocks arrived yesterday. I'm still getting my head around a setup that will hold the new dove tail rough to the blocks for cutting. I'm leaning towards making a pair of fixtures I can bolt to the bed, and they will have a 45 degree face that I can bolt to. I'll drill and counter bore 8 holes in the plate first to match the 8 on the Z slide. I can set up the V blocks and using some long parallel bars from way way back when. get the blocks aligned to the X axis and locked down on the bed. Then put the two fixtures in place, Hummm four will be better, one on either side of each V block so when I snug down the plate, it doesn't introduce a bow to it. That will pull the plate tight to one side of the V. I've still got to get my head around the pulling it to the other side, IE the bottom of the V
