This is a photo of our machine arriving today. De-crating the new machine. Yeah that's snow on the ground. Machine passing through the door.

Mike hard at work... watching the the riggers. Pallet removed. Getting ready to rough set the machine. A photo of the new machine. It's a Mori Seiki DuraTurn 2550.

This is another photo of our new machine. The photo shows the 12 tool changer. The Denny from Ellison Machine spent a long cold day moving, leveling and unpacking the lathe today. It's looking like it's almost ready to start making chips. Two months after we ordered our new lathe the power company is here to hook up the power.

We have started cutting the bar stock for the trial runs on the new lathe. The bar stock is 9.5 inches in diameter. The slab starts out about 21.2 lbs and when it's finished the rotor will weigh about 3.6 lbs. We started turning test bowls today. We have been working to refine our tooling for the new machine and prove our code. We've been making a number of design refinements that will enhance the performance and improve the rotor design. It will be well worth the wait. The rotor is coming along nicely.

Turning the lids has been an adventure. This is our latest fixture. It's fast and creates a clean chatter free finish. Yes that's a lawn mower tire! Another 1000 lbs of aluminum arrived. We'll cut this round bar into billets on the band saw. This is a picture of the large fixture that is used to machine the lids for the turn key.

We needed to setup the fixtures to drill and tap the castings. We decided to put our manual mill back into service. First thing it needed was an extension. This photo shows the head removed and the extension installed. Because the casting are large we need a little more height in order to get a full swing out of the rotary table with the casting mounted. This is a 1 inch riser plate we whipped up. Simple but it works. This is a picture with the rotary table remounted.

This is a casting mounted to the rotary table. This should make drilling and tapping the leg holes much easier and more accurate. Leg drilling fixture. Toe drilling fixture for the centrifuge leg.

Quick fixture to drill the switch holes in the motor covers. This is the complete fixture. The results are a nice clean, bur free, hole.

Mike didn't know I took his picture while welding. Tapping the holes for the lid studs. Recently we decided to move the lathe about 70'. We purchased some heavy skates from Northern Tool. Here is the lathe on the skates in it's new location.

Steering the skates was easy with a couple of steering hooks we made. This is a photo of the steering hook. We slit a scrap of 2x4 tube and welded it to some scrap pipe. I was afraid the pipe might bend but they worked perfectly. We made two, one for a front spotter and one for the rear to keep everything aligned while moving. Christmas Eve 2008. It has been a long cold winter with a lot of shoveling.

Last fall we purchased a Dynatorch CNC plasma table from a shop that was closing. It was complete and never installed. It took a few months but we finally have it working. It has a 4x8 down draft table which is nice. No smoke. Ducting the down draft table. Ducting the down draft table.

Magnetic starter for the 3 HP blower on the roof. View from the ground showing the safety disconnect. View from the roof. We had a short break in the snow last week. Good thing we finished before it started snowing again.

My kids spend a lot of time at the shop. Six or seven years ago we installed a small climbing wall in the office for them. My wife wanted a chin up bar and I figured making one that would bolt to the wall would be a perfect solution. This is mounted in an un-used part of the wall anyway. Few minutes on the cnc plasma and some welding. Overbuilt but it's all scrap.
