How I made a jigsaw out of wood. Blueprints. Part 1

This machine will be 5 years old in the spring. During this time, with quite frequent use, the machine shows itself well.

Initially, I made such a machine according to the drawings from the magazine "WOOD", but after three months of use, I discovered a number of shortcomings in it and decided to develop my own machine.

First I made a project.

I decided to make the base of the machine on four supports and high so that I could work while standing.

Made from pine. Below, leafing through the gallery, you can see the main stages of making the base for the machine

I made the rods of the machine from ash. (I think you can make them out of plywood)

To attach the rods, I made a separate block from pine blocks.

The rods were fixed between these bars using bearings. In each rod I put two bearings on both sides. As an axis, I selected a piece of a nail that is suitable in diameter. In the bars, between which he clamped the rods, he also put bearings. This block with rods was pulled together with threaded rods and nuts. (Scroll through the gallery)

Next, it was necessary to connect these two parts - the base of the machine and the block with the rods - together. Also connected to threaded rods with nuts. Previously, holes were drilled in the block with rods, he fixed it with clamps to the base of the machine and made sure that it stood exactly with right angles and in the center. (Scroll through the gallery)

I decided to use a threaded rod to tension the file.

To fix it in the rods, I drilled holes and cut grooves so that the rod was located in the center of the rods.

Next, it was necessary to make a pusher for the lower rod. I decided to use a jigsaw as the engine. His saw moves progressively up and down and it was necessary to transfer this movement to the lower rod of the machine. For this, I made a pusher that would transmit this movement. Later I pasted a jigsaw file into it.

The thickness of the central part of the pusher corresponds to the thickness of the rod.

The next step was to make the saw attachments. The mount was designed the same for both the top and the bottom.

I cut the clamping plates from an old hand-held jigsaw. The hook for the bindings was made from a suitable piece of iron, and more specifically, a U-shaped clamp from a Soviet trellis went to make it. Such clamps were used to connect mirrors to trellis cabinets.

Next, I bolted a jigsaw to the base of the machine and adjusted the pusher so that when the jigsaw is in the middle position, the lower bar should be parallel to the table grounds. That is, the distance from the base of the machine to the top of the bar must be the same along the entire length of the bar.

The pusher had to be shortened and the slot deepened for the saw. Then I glued the jigsaw file into the pusher.

Last but not least, I sawed out a table and a support arc for it.

At this stage, all parts of the machine were ready and you could start setting up.

Setting up the interaction of all parts of the machine is perhaps the most important part for further comfortable work.

I will talk about setting up the machine in the next part. And now I propose to watch a video with the highlights of the manufacture of the machine.

Machine drawings, fixtures and parts list for manufacturing can be downloaded link.

Machine setup will be discussed in the next part.
