* self-tapping screws for wood,
* glue for wood,
* screw-in nuts for wood (furniture),

As you already understood from the video, the machine consists of two parts – a table and a removable guide for the jigsaw blade (I do not take the jigsaw into account, since everything is built on its basis). And yet, I don’t give the dimensions, because I don’t know them, here you can also improvise according to your wishes and preferences.
First of all, the author started preparing the table parts and assembling it. I cut out a rectangular workpiece – a tabletop. I made markings on it in the center – the point of intersection of the lines is the place of the hole for the jigsaw blade.
Then he installed the jigsaw, as it would later have to be fixed to the tabletop. With the help of a special device (I think I also made it with my own hands), I marked the boundaries of the instrument. Then he chose a rectangular groove for the installation of a jigsaw as a mounter.
I installed the tool and marked a place for the hole. Drilled it.
Now it is necessary to provide for the fastening of the tool in the groove. To do this, I unscrewed the tool sole plate. Put it in the groove. I put marks on the holes of the fastening bolts with an awl. I drilled holes on them. Then he again installed the jigsaw in the groove and secured it with bolts (from him) by screwing them through the holes. But since the bolt heads are countersunk, they protruded above the surface. This working surface and the caps will interfere, so the author unscrewed the bolts and countersinked the holes for the caps a little. Now everything is neat and nothing gets in the way.
Next, the author installs a guide on the tabletop (for what it is, it will be clear at the end, although if you watched the video clip, you already understood why it is needed). Also, with the help of the device that was used to sample the groove for the jigsaw, I chose the groove for the guide. In the part itself, I drilled several holes for fastening and slightly expanded them under the heads of the screws, with which I fixed the part in the groove of the tabletop.
Next, the author took up the sides of the table. You will need two such parts. First, he cut out two rectangular pieces of the desired size. One of them was marked with markings. I cut out the excess on it with a jigsaw. I made the second side in the same way. From myself, I can assume that I cut out the openings in order to reduce the weight of the structure. I drilled holes for mounting screws in the prepared parts (sidewalls) on a special device.

Step 5 .
Now let's start assembling the table. To connect the parts, the author used self-tapping screws and wood glue. The details were fixed together with the help of corners and small clamps. At this stage, you can also see how he sets the sidewalls a little narrower from without openings. This is just one of those moments that I mentioned at the beginning of the article, there is no manufacturing process for these parts, but here I think everything is clear. After the table was ready, I fixed the jigsaw on it and performed a test cut of the workpiece. Everything works fine. Let's go further.
At this stage, the author started making the guide. It consists of two parts – a box and a strip. First, he prepared the parts for the first and assembled a rectangular box from them. Glue and clamps were also used here.
Putting aside the box, the author made the guide part itself, which will be mounted on the bar. By the way, the bar itself is already ready, there is no manufacturing process.
The base of the guide is a metal corner. There were holes in its shelves (two each). In one of the shelves, the author cut out a piece between the holes, a groove turned out. Then he took the bearings and fastened the bolts into them. The finished rollers were fixed on the corner in the groove. Then he fixed the guide to the bar. The photo shows that furniture nuts are already screwed into the finished strip on one side – two along the end and two along the side. This is done so that the guide can be fixed in two positions. In the process, you will see everything for yourself.
Step 7 .
And so the second part of the machine is assembled, now you need to fix it on the table. For this, the author first prepared the fixing screws. He used an ordinary bolt, on which he fixed a screw plastic part (apparently such things can be ordered on the Internet). With these bolts, I screwed the rail with the guide to the box. The detail is ready.
The next thing the author did was drilled holes in the side of the table along the marks. He screwed furniture nuts into them. I screwed on the bar, adjusted everything and made a test run again, but with the guide.
Further on the photo we see how the author changes the position of the guide with rollers. This is exactly the point that I wrote about earlier. Having installed the guide in this position, the previous fastening of the bar is no longer suitable, now it needs to be fixed on the other (adjacent) sidewall. Which he did, the process is the same.
Step 8 .
It's time to remember the rail mounted in the tabletop. Now you will understand what it is for. But first, a few points. The author placed a movable stop in the guide, which is fixed by clamping the nut. Then, from the two parts that you see in the photo, I made a retainer. This moment is clear from the video.
Next, the author takes a rectangular workpiece, drills a hole approximately in the center and string it onto a retainer. Then, with a simple movement of the hand, a circle is formed from the rectangle. Smooth, neat, fast and convenient.
On this, in principle, you can end. The photo below shows how the author changed the blade to a larger one and now you can cut fairly thick workpieces, as you can see, the cut is perfect.
He decided his design still improve more and connected the jigsaw through the pedal, now it is even more convenient to work on the machine. You don't have to climb under the table top to turn on the tool.
That's all, thank you all for your attention, good luck and see you next time at C amodelkina.
