My one regret with this project is that I didn't take lots of process pictures, so most of this is going to be show and tell without too much of the showing part...Oh well.

First up was a lot of rough cutting stock. After that I was off to weld up the bed first. I used angle iron, square tubing, and a section of C channel to create the bed. The square tubing would eventually be filled with sand to add mass and reduce vibration. Once the bed was welded and surfaced, I suspended it off the mill with an angle plate that would make Paul Bunyan feel like a little man.

This operation was to square up the end relative to the top of the bed. A large plate is then welded to this surface and is used to anchor the bed to the main pillar that supports the headstock.

Back to welding! At this point, I welded a 1" plate to one end of "Mr. Beam" to become the surface that supports the headstock. I don't have any photos of Mr. Beam before he put on a couple hundred extra pounds, but if you imagine an H beam with a 1" thick plate and a 3/4" web that's roughly 9" square, you've just seen Mr. Beam. This thing was not fun to manipulate while machining, but has certainly made up for it's initially PITA qualities. :)

With the top plate welded on, I (and a couple friends) put Mr. Beam on the mill with a 90º head attachment to true this surface to the area where the bed of the lathe would attach. With Mr. Beam still on the mill I drilled and tapped for the locating pin and bolt holes that would marry the bed and Mr. Beam.

Now that the machining was finished, I took Mr. Beam outside to weld some steel plates on the two open sides, effectively turning it into an enclosed pillar.

At this point, I fabricated a leg for the unsupported end of the bed. By welding two pieces of C channel together along with a mounting plate, I had the makings of a leg. I then added some off cuts to form mounting points for rubber feet machine levers. The last thing was to fill up the foot with sand and then weld a plate onto the bottom so that the bed and leg can be bolted together. I successfully made a 100 lb leg!

I assembled the three pieces and stood it up next to the milling machine. Now it's time to drill and tap the top plate to accept the Logan headstock. This is the only time I've used a mill to drill something not attached to the table. It was an interesting process to say the least and quite time consuming to position the mill head in just the right place before each hole was drilled and tapped. The good news is that once the entire lathe was assembled, everything lined up dead true!

If you can't tell by now, the name of the game is mass. :)

Now onto the the finer details that probably don't require as much story time. After making the "body" of the lathe, I moved onto fabricating the banjo and tool rest. I made a cam shaft that's around 32" long out of 1 1/4" 4041 steel. That thing is beefy and it works great! The banjo is made from a piece of C channel with a plate welded onto each end and also on the "open" side that rides along the bed. On top of the banjo is an 18" rod that's 3" in diameter, which holds the tool rest with a lock similar to those found on the quill of a milling machine.

Now it was time to get started on the power plant for this machine. I bought a motor mount plate instead of fabricating one and attached it at the bottom of Mr. Beam on the back side of the lathe. Given the constraints of my materials, I opted to use a countershaft arrangement and fabricated a support for it with some 1/4" H beam and steel plate. Two pillow blocks sit atop an assembly of 80/20 in which the countershaft is supported. This construction, while not very pretty, did allow for quick fabrication and the ability to easily tension the belt that connects the countershaft and headstock pulleys.

Onto making the tailstock! Once I welded a 1" thick plate to the bottom of a 6 x 6 square tube, I milled away the 1" plate to form a tenon that locates on the lathe bed and keeps the tailstock true to the headstock along the length of the bed. I milled mounting holes for the cam lock and fabricated the necessary pieces to lock the tailstock in place along the bed. With this done, it was time to drill a locating hole in the tailstock with the headstock off the lathe. But first, I had to get the motor running...

After this, I turned the quill sleeve and milled the necessary features that would attach the sleeve to the tailstock. The quill on my lathe is advanced via a rack and pinion. At this time, I also milled out the necessary material to allow for the gear to mesh with the rack on the quill and also drilled for a quill lock.

With the quill sleeve finished, I put the tailstock on the mill and indicated on the dowel pin that was pressed into the tailstock. I opened up this hole to accept the quill sleeve with the snuggest of slip fits and drilled and tapped corresponding bolt holes to firmly attach the quill sleeve to the tailstock. After a few minutes of assembly, the tailstock is finished!

This shot was taken before the tailstock was completed. It was no small victory seeing the centers line up!
