12 years of work, on and off of course. Some of the time was spent pondering how to make it work. I call that time pondering working on it. There were no rules or instructions. The only thing I had to start with was raw castings and an idea of how it should be. Here is the result of time well...

Slow motion of number 3 running. Note the torque of the power stroke, enough to lift the motor off the table!

Yes, that is right. This is the third one of its kind. This one features a different style governor, instead of a wedge it uses a dropping collar, the switch is a direct press instead of leaf spring and uses a 6VDC commercial coil, the same as the first one. The gears are plastic. This motor...

Finally! A video and in slow motion so you can see the operation in detail!

Here is the sequel to the motor that was finished in 2003. It is made out of bar stock. This build started in February of 2013 and was finished this past February. It runs fairly slow and fires once and coasts for several revolutions before firing again. If you have seen my other one at the...

Complete running solenoid motors for sale. I also sell parts to build solenoid motors. I have simple plans to build your own too. PM me if you are interested.

Nice engine. It looks like there is quite a bit of flex in the mount for the cylinder. If it fatigues it could break off in my opinion. Maybe run braces back from above the cylinder to the main bearings?

Finding an exact sized dove tail cutter is not very easy. I use the round wire method to size the male and female dovetails. The dovetails on the tool holders you see in this thread were cut with one pass of a straight sided 2 flute milling cutter, three planned passes with the dovetail cutter...

You do nice work. You can test the efficiency of the fan by slowly spinning the wheel and using a little smoke. My best guess on this design is that the tendency will be for the air to spill towards the rim than in line with the shaft.

Hey there Mawito I am unable to measure them at this time but it seems that the cutter used for this job is a 60 degree that is .375 in diameter at the big end. I pick up cutters like that at our local model engineering show. I am almost tempted to make the QCTP it self so I can have one for...

I've converted two Taig lathes to use a lead screw for the saddle travel. Installing the lead screw was the single best mod for the Taig in my opinion. The second best mod was adding a variable DC drive. I would love to see the cross slide mod when it is done.

Mawito, I've included a couple pictures that better depict how the post is mounted. The holders are for 3/16" tooling. The size is a perfect match for the Sherline. The Levin QCTP is even better on the Taig lathe which is handy capped by limited cross slide travel which is hurt further with a...

The price (see the link in the original thread) of the three piece set is a shocker no doubt. If I bought the extra 6 tool holders I would have shelled out $2250 plus shipping from Switzerland. These do come up for sale once in a while on eBay which there is a set right now for $700...

What do you do when you are on a budget but need extra tool holders for your Levin (Tripan) http://www.levinlathe.com/page15.htm quick change tool post? After viewing what they want for individual holders I broke out the dove tail cutter and just made some. I made them using aluminum but plan on...

Crank off the top slide exposing the lead screw. Make sure the lead screw is pushed all the way into the bearing (toward you if you are in front of the lathe) so the maximum amount of shaft is protruding out the front. Make sure the nob is on all the way and tighten up the set screw. I am...
