I admit putting the element in the floor was not ideal but it was all I could do as a fix to the design flaw. If I were to start over I would provide twice the number of groves for the element to rest in. After each use I vacuum out the kiln once it has cooled. It was still very hot when I took...

These parts are the base of the steam chest. The valve surface will be milled flat and made smooth after the parts have been attached to the cylinders. I was thrilled to be able to cast these with the steam passages. The drawing shows a cutaway of the part. Valve chest and cover. Steam...

Eventually I started getting usable parts. Here are the parts for the steam manifold. The elbows turned out OK, just a little surface issue on the flanges but a little sanding will fix that. The tube was a failure. The small amount of layer marks left from printing the parts are largely removed...

This is a failed part that was cast in a flask that was too hot. The metal was to hot and the burnout was not complete. Here is another failed part. This one the flask was to cold, metal was to hot and the burnout was not complete. Eventually I started to get better results. One big...

How much do they cost? Are they made to fit a particular kiln? The element I have made cost me $10 and it takes me about 3 hours to make and install. It tops out about the same as yours. The investment plaster I have been using works best at 1400F, or 760C. when used with a printed resin...

Update 3 I have added a a false floor to my kiln to house an additional length of element. I was having problems with the element getting to hot and failing. With this extra extra length I was able to fit an element made from 46 feet of 18 gauge wire. The new specs are 2400 watts, 24 0hms, 240...

Marks Monitor Build A little history can be found here USS Monitor - Wikipedia The Iron Clad USS Monitor was designed and built by John Ericson for the US Navy during the American civil war. The contract required the ship to be built in less than 100 days for a cost of $225,000 with a...

I found that with CNC routers that are used to cut wood, the dust soon clogs up the nut when oily lubricate is used. If you are going to try a lubricant it needs to be a dry type. Mark T

I built my machine in 2000 and I have had the same issue. Mine is a twin of your machine. I took the nut apart and cleaned it out then reassembled the nut adjusting the spring to be a bit less tight. Never ever use spray paint anywhere near the CNC. Don't ask me how I know that. Anyway buffing...

My wife loved (me) doing everything to do with (her) vegetable garden. I don't even like vegetables. So I built a wood shed on her plot. Problem solved.

I have the Grizzly 4003G 12 X 36 (Gap Bed) and find it to be a very nice lathe. I added a DRO and a collet chuck. It came with everything else it needed. Paid $3600 but that was a few years ago. Mark T

It is true that I am building the Monitor engine to the plans of Richard Carlsetdt. Not much to show yet. I look forward to watching this thread. Mark T

Sometimes, and then I do chores that I have neglected and soon I would rather be building an engine. Mark T

I have two treadmill motors in my shop. Rated at 2.25 HP. They are 9" long overall including stub shaft and a little under 3.5" in diameter. 300 RPM to 4600 RPM Mark T

You also need to take the transformer from the old treadmill, the control board (not the one that is the user interface) and the motor. The motor usually has a flywheel but is not needed, just remove it ( it unscrews) All the control boards I have looked at are well labeled so its not hard to...
