Simple Homemade Miter Saw Clamp - From Existing F Type Clamp | DIY

If you have a miter saw, you may got it without a clamp, used for holding the material you cut (Or maybe your clamp just got lost...)

I got this great old Makita sliding miter saw lately, and it was without it's original vertical clamp.

I checked on the net, and saw that such original clamp price is around 40 USD. So, I decided to try making one myself, using materials that I had at home.

As you can see in the video, I used an existing simple F type adjustable clamp (which costed ~4 USD), and some scraps of wood.

It took me about 30 minutes to make this project.

Materials:

• F type vertical adjustable clamp
• Some small pieces of scrap wood
• Strong glue (for metal + wood)

General List of tools I'm using - https://www.itzikdiy.com/tools-list?m=1

Tools in this Instructable:

• Miter saw
• Measuring tape
• Dremel or angle grinder, with metal cutting discs
• Safety glasses
• Another clamp
• Knife
• Drill driver
• 19mm drill bit
• Sanding paper
• Caliper measuring tool

This is the original F type clamp I used.

You need a clamp that after cutting it, it would be smaller than the intended clamp hole, in your miter saw.

I marked the cutting position - so the new clamp length will be about 10cm long.

I took Dremel 4000 with a metal cutting disc. You can use angle grinder as well.

I cut the clamp in the marked position.

I inserted the clamp to the intended hole in the saw, to check that it fits.

Since that the clamp doesn't have rounded rod, I needed to make it rounded, so it would fit the intended hole in the miter saw.

I took a piece of square wood profile and carved it with a knife, so it would be round and fit the hole tightly.

(If you have a rounded wood profile that fits, you can skip this step).

I took the rounded wood profile, and cut it along, with the miter saw, and later cut the 2 splitted pieces.

I took the 2 wooden rounded pieces and put over the clamp rod to check that it fits.

I put a very strong glue over the 2 sides of the clamp metal rod.

This glue is good for wood and metal as well.

I put the 2 wooden rounded pieces over the clamp rod with the glue.

Then I put it to dry, holded by another clamp :)

After full dry, I sanded the new wood base a bit, with a sanding paper.

Basically, the clamp is ready.

Since that the clamp press plastic cover was lost, I decided to prepare a wooded press base.

I measured the diameter of the clamp metal press, using a caliper measuring tool, and it was ~19mm.

I took 19mm drill bit and drilled a rounded socket in a piece of wood board.

Later, I cut around the socket, with the miter saw to have a small rectangle piece with a socket.

I put the new miter saw clamp in the intended hole in the saw base.

I took the wooden press base with the rounded socket I made, put the same glue that I used before, inside the socket, and tightened the clamp metal over it.

The miter saw clamp is ready!

I put the final miter saw clamp in the intended hole in the saw base and started to use it for different cuts.

I started with cutting long 7*7cm wooden profile, and holded it with the clamp.

It holded it very well.

Another usage, of holding wood piece which is far from the fence. For example, in half lap joint cuts, when the wood shouldn't be close to the fence, so the cut will be straight and not rounded due to the saw blade.

In this case, I put another small piece on top of both long pieces, so it would press them both.

Last usage, is for cutting small pieces of wood.

I put a jacking piece of wood, on the left, higher than the piece I'm going to cut.

Then I put another piece of wood diagonally, over both the left piece and the right small piece, so it would press it tightly with the clamp. Finally, I cut the piece.

Note: In the video I'm showing cutting of smaller pieces than in this example.

These pieces are smaller than the saw's fence middle spacing.

After some people watched my video - I was warned that this can be very dangerous, since that although the clamp presses the small piece, due to the speed of the saw blade, cutting without the fence support can cause the small pieces can fly like a rocket.

That's it, you can watch the video to see the full process and some uses of the clamp.
