Well I am starting the build of my machine #3. I have always been intrigued with V-bearings, so I bought a couple of sets and plan to give them a go. I will give ply/MDF one more try. I am itching to mill aluminum, so am hoping that this machine will give me the strength to do it.

I kind of started this log before, but it digressed into epoxy and suchnot. This project will probably take a little while as I want to test and change as it goes along. I have been thinking about it for months now, and I have decided on a 24” x 40” with about 4” of Z.

I am going to try to get rid of the support of the gantry under the bed. This means that the gantry will have to be stiff. It will probably take a couple of tries to get it acceptable. It will be stiffer than the drawing suggests. This also means running the X leadscrew on the side. This in turn may lead to dual leadscrews, which will be a new adventure for me.

Comments always welcome,
Steve
