We make a circular from a regular drill. Step-by-step instruction

Greetings gentlemen, homemade products. Today we will be making a circular saw out of a regular household drill. Such a circular for an industrial scale is certainly not suitable, but for household needs it will be quite normal.

As always, I will not indicate the exact dimensions and give only an idea, and you already make each one according to your needs. Let's start making. The first step is to prepare the drive for the disc. We take a bearing (preferably a closed type) and a bolt. Here, see for yourself what dimensions you need, but the point is to insert the bolt head into the bearing.

To do this, we grind down the corners of the bolt head and round it off.

This is the result we get. It is important not to sharpen the cap so that it enters the bearing with effort.

The bolt plays the role of a drive shaft on which we fix the disk. To do this, take two washers and a nut, the whole set is in the photo below.

We put the disc on the bolt, put washers on both sides and tighten with a nut.

Put the bearing on the ground off head of the bolt.

You will end up with such a design.

Now we are making the frame itself for the circular. The photo below shows that we use plywood sheets for the bed, but in your case it can be any other material. It uses one large sheet as a common base and 3 small sheets as a bed for fixing the drill, which are stacked one on top of the other.

To attach the drill itself, we use a metal strip in which we drill 4 holes.

Now attach the metal strip to the drill in place of the handle.

The photo shows how to install the drill. We attach the metal strip to the base with self-tapping screws.

Insert the disc into the cartridge. Look here, the base for the drill should be of such a height that when installing the disc it is naturally higher than the bed.

Now we make a headstock for the bearing from a regular board. As in the photo, sketching the board and marking the bearing location.

Drill a hole along the bearing diameter with a feather drill.

We put the board on the bearing and fix it with screws to the frame.

In fact, the circular is ready, now we are making the top cover, the working table. To do this, take another board and set it to the end. The arrow shows the place where we need to install the door hinge.

We fasten the loop to the board and place the board in place.

Now we install the desktop itself, for which we use the same plywood sheet.

We attach the desktop to the hinge as shown in the photo. Now it will open with us.

After fixing the desktop on the hinge, start the drill and lower the tabletop, thus sawing the working hole for the disc.

So our circular is ready. The author of the idea installed special guides at the bottom of the desktop as shown in the photo. If I understand correctly, this is to prevent the desktop from shifting.

If I were the author, I would have acted here a little differently. I would install not one but several door hinges, which will already prevent displacement. I would also strengthen the very design of the circular case. In general, it is clear that the author was doing it in haste and not all the points were thought out, but the idea itself is quite worthy.

On this you can finish, and if anyone wants additional troubles, then a stop bar can be installed on the desktop as in the photo below. A very useful thing.
