Hi everyone! I wanted to have some good bar clamps. So i watched a lot of videos and DIY tutorials to built my own. A lot of them are great but in my opinion you have to do too much detail work for each one of them...

So I decided to create my own an mill them with my cnc.

Step 1: Gather Materials and Tools

Materials you need :

-18mm thick Plywood - for one Clamp you need 3 pieces:

~ 100x200mm

~100x120mm

~100x160mm

- 1x M10 x150mm threaded screw

- 2x M10 Nuts

- 1x M10 thread screw connector

- 2x M6x40 screw,nut and washer

- 1x M5/M6 screw 20mm

- 1x Square tube 1m long 20x20mm

- some screws about 40mm long

Tools you need you can see in the picture. Nothing special...except the CNC

Step 2: Milling All Pieces

The real first step is to mill out all pieces. I added my depths for you as a reference.

Unfortunatelly something went wrong during milling the last part but i kept it anyway because it didnt matter

Step 3: Cleaning Up All Parts and Testing

After milling I had to remove all the fuzz and i tested if the parts fit properly. I put the M10x150mm screw in position. Then I checked if I was able to turn the screw when the parts are put together.

After that I checked if the milled slots had the right size for the square tube. Luckily all parts did well.

Step 4: Screwing and Glueing All Parts

Now i marked all holes free hand with a square and drilled them with a 1mm smaller drill than the screws. Then I countersinked the holes, put some wood glue on the parts and assembled them together with the M10 rod and the connector

Step 5: Machining the Square Tube

On one end i drilled a 6mm hole and assembled a 6mm screw and nut to avoid the movable part from slipping of. After that i drilled a 4 mm hole like you see in the picture in the movable part. Through this i had the first postion for the holes on the tube. After that I made a mark each 45mm on the tube, drilled them with a drill with the same size as the head as the M5x20mm screw. I used a 10mm thick drill bit.

Step 6: Assembling Last Parts....

I assembled the last two parts and marked the holes for the last two screws on the tube. Then I removed the wooden parts not to damage them will drilling. Finally I assembled them to give it a try. At the end of the M10 screw I screwed on a Nut, a wodden part from a previous project, an another nut. It works pretty good.
