If ever anybody had any doubts about building their own equipment they now know that it is possible. No machine shop required. Just the desire to want it.

This is a fantastic thread. for sharing it with our members.

Cheers  :beer:

Thank you BrassMachine and Dsquire!  It's a pleasure to post these pics here with this group of creative people -- most have never been posted anywhere. I kind of forgot about it until you guys asked, and now editing and posting them and writing them up brings back what an exciting time it was to be doing all this and learning about how tools worked, casting, figuring out how I was going to get to the next step, etc. I lived and breathed this stuff for one winter. My thanks in turn have to go to David Gingery for setting me on that course, and giving me the capability and confidence through his books. The guy ought to get a Pulitzer prize for those typed up pages and hand drawn figures in a half dozen little paperbacks that he published himself.

Anyway I suppose you want to see more of this project, so here goes.

The other side of the vertical slide with the added on piece on top. I've added a split dowel to act as a core print for a hole I want in the finished casting. The imprint it leaves will be filled with a sooted steel core, and that will be knocked out of the finished casting to leave a circular channel.

After casting these parts I was just about ready to mill them in the new milling and boring table. But since they would be rather high, I needed one more adjustable fly cutter -- of smaller diameter than the other two. Together the three would give me the full range for milling. This last one was essentially a boring bar, and could double as such. To make one you just drill two holes in a piece of cold rolled steel. Square one out to fit a piece of lathe tool -- I do this with a small triangular file -- takes about ten minutes to do. Then, tap the other hole in the end to take a set screw (fixing bolt). That's about it. This tool can bore, mill, and cut gears with the appropriately ground bit of lathe tool.

Here I'm tapping the end. Naturally not using power, -- just rotating the headstock pulley by hand, while keeping light pressure on via the tailstock wheel.

vtsteam:
And here we are finally ready to mill the front face of the new vertical ways base. The face that will be milled will later get a slab of cold rolled steel attached. The trough is to take the lead screw.

I've bolted to the milling table the two plain bars we cast earlier -- now cleaned up and drilled and tapped to act as a vice. The screws which clamp the work are angled slightly downwards so they apply down force to the casting -- keeping it tight to the milling table. Since there are 4 of them they can accept irregular shapes. The other accessory castings -- the L shaped wing pieces have similar capability -- but they aren't used in this step. All four clamping pieces can be used at once if needed.

Making the first pass with the milling table -- what a great feeling that was! It was working!
