Homemade jig machine. Replacing the engine. Reasons and results

I previously wrote about my favorite machine. He works for me now in its fifth year, and works well, but I decided to replace his engine.

Earlier, as the engine of this machine worked jigsaw with speed control. Adjustment is necessary, because of higher vibration and sawing can break at high speeds. I basically cutting out takes place at the speed of less than 1,000.

Why I have decided to replace the engine.

Our mains voltage constantly jumping, and collecting the engine, especially at low RPM is quite responsive to these differences and have to constantly tighten up control speed.

As a result, I decided to replace the jigsaw on the engine from the washing machine. That's what came out of it.

The engine is put at the bottom of the machine base. As far as I was able to determine the appearance of the engine (the markings on it is not found) and search on the internet - this engine is 90 watts and 1,200 rpm.

I immediately decided to make a smaller turnover for a more comfortable work.

Turnovers are regulated by pulleys. The shaft has two identical plywood, and the second pulley block has two dimensions, and decreases to 800 rpm and 600.

For information. jigsaw machine HEGNER Polycut 3 a belt drive. In the description of the machine indicates that the transfer not only allows you to adjust the speed, but also increase the cutting effort.

The second block is mounted on bearings connecting rod which on the other hand is attached to the lower rocker machine.

Lowering pulleys fastened to plywood block, wherein the both sides put the bearings and the shaft is mounted from the threaded rod.

The very same engine is bolted to the plywood parts, which is fixed on the basis of the machine.

What got the results from the substitution.

At first, The machine has become less noisy.

Secondly, Nail file is now moving smoothly, with the same speed, voltage fluctuations in the network is not affected.

ThirdlyDue to uniform motion nail files, to better manage the process itself cutting. That is a much better control when sawing complex, small patterns.

See how a machine with an updated engine can further be in the video.
