TWO IDEAS FOR A DRILLING MACHINE

Send

See how you can make two very useful fixtures for a vertical drilling machine, which will definitely be useful not only to any master, but also to an ordinary amateur.

1. Nozzle for grinding under a drilling machine

For the manufacture we need:
Fiberboard or plain board

Bolts, nuts, washers.
PVA glue.
Drills for wood.
Sandpaper.
Bearing.
Rasp.
Construction stapler.
Pliers.
Screwdriver or screwdriver.
Self-tapping screws.

Assembly order

In our case, we use fiberboard, because there were leftovers at hand. But there is no difference, you can take an ordinary board. Cut it to the size of the desktop of the drilling machine.

We mark and make holes for attaching to the machine. Next, drill holes for the bolt caps so that they do not protrude. It is more convenient to do this with a pen drill.

We fix the fiberboard panel on the drilling machine using bolts with nuts.

Then we fix the core drill in the machine. The diameter of the drill must match the diameter of the bearing used.

We drill a hole under it and make a hole under the cap of the bolt.

We put a bearing on the bolt and clamp it with a nut.

We cut wooden circles with a core drill. Select the diameter to fit your needs and preferences.

Then we coat them with PVA, assemble them onto a bolt and clamp them with a nut.

A larger washer must be placed under the nut so that it does not cut into the tree. Tighten as tight as possible so that the gluing is reliable.
We fix the resulting roller in the cartridge, and we lower the lower part with the bearing into the fiberboard hole by adjusting the height of the desktop.

The wooden roller has some beating that you need to get rid of. We bring it to a round shape using a rasp. The better its processing, the easier it will work in the future.

Next, glue sandpaper with PVA glue.

Fix until dry using a furniture stapler.

Do not forget to get staples at the end of gluing!

Main advantages

The grinding machine is ready. It can be modified with a small stand.

It is especially convenient to grind parts with internal radii, but processing straight lines will not be difficult.

This home-made machine is characterized by high performance, ease of assembly and low cost components, compared with factory counterparts.

2. Table for drilling pipes and round profile parts

For the manufacture we need:

Metal corner.
Metal plate.
Bulgarian.
Welding machine.
Ruler.
Bolts, nuts.

Assembly process

First, with the help of a grinder, cut two corners of the same size.

Then we weld them to the plate butt, as shown in the photo.

After welding, we clean the welds and the part itself.

It can be painted at your discretion to protect the product from corrosion.

Now we fasten the plate to the drilling machine so that the drill fell exactly in the line of junction of the two corners.

We fix on bolts with nuts. Choose the dimensions of the plate and angles taking into account the need for the workpiece and the size of your drilling machine. The product is ready for use.

Main advantages

Thanks to the same angles centered relative to the drill, you can make a hole in any pipe or round part exactly in the center, without displacements and skew.

And due to the shape of the corners, it will be securely fixed and will not move during drilling.
This design is characterized by high reliability and accuracy of drilling.
