Introduction: Homemade Table Saw Fence Mechanism

About: Hello there! Thanks for stopping by! I'm Elias and I'm addicted to Making, Building and Creating any kind of things, producing free DIY videos and showing you How it's done, step by step! Here you can see some…

In this instructable you'll see: How I built an easy, quick, simple and really steady homemade table saw fence mechanism, made of MDF, OSB, Pinewood, Plywood and a pair of ball bearing drawer slides.

Step 1:

Firstly, I cut these pieces for the fence, which are made of OSB.

Step 2:

Because I didn’t have a single big piece of plywood, which is a really good wood for many uses & constructions, I made this project from woods I found in my workshop like (MDF, OSB, Pinewood & Plywood).

Step 3:

Because OSB leaves splinters, I had to sand every surface of the wood really well.

Step 4:

I assembled these pieces of the fence in order, from the biggest, to the smallest.

Step 5:

The big piece is 60 by 7cm, the middle one is 40 by 7cm and the small one is 20 by 7cm.

Step 6:

I repeated the same process for the other piece and then I rounded all the edges with the router.

Step 7:

Now for this part of the fence I cut a big piece of OSB, with dimensions 1,2m by 10cm.

Step 8:

In order for the pieces of wood, that I will later cut, using the table saw, to slide smoothly on the fence, I also glued a piece of plywood 4mm thick over the 15mm OSB piece.

Step 9:

I clamped them down together and let the glue do the job.

Step 10:

For this part of the fence, I cut 4 pieces of 91,8cm by 7cm, the length depends on the thickness of the drawer slides and the width of the surface of the cabinet I’m going to make.

Step 11:

I used this piece of OSB to find exactly the center of the other piece of wood and then I drilled holes on all 4 sides.

Step 12:

Then with a countersink bit I drilled all the holes again, so that the head of the screw that I will later place, can go under the top of the wood without splitting it.

Step 13:

I sand it very well and rounded all the edges.

Step 14:

Then I cut this part of the fence which consists of two 8,5 by 8,5cm pcs of plywood.

Step 15:

Nailed them, drilled them, countersink the holes, screwed them, sanded them and rounded all the edges.

Step 16:

Now, under the top of the table saw there is this piece of OSB, which consists of one piece with dimensions 70 by 7,2cm and two pieces with 70 by 4cm.

Step 17:

...and I repeated the same process... nailed, drilled, countersink the holes, and screwed.

Step 18:

Also, under the top of the table saw there is this piece of plywood with dimensions 7 by 7cm, that is going to slide into the slot I previously built.

Step 19:

After the piece of the fence has dried, it’s time to cut the extra piece of plywood.

Step 20:

Now, for the top surface of the construction, I used MDF: 1,2m long, 80cm wide and 2cm thick.

Step 21:

Then, I made exactly in the center, a slot using the router, in order to be able to move the fence with the bolt and tighten it at whatever length I wish.

Step 22:

Then I cut some pieces of pinewood in order to keep the whole MDF surface straight and so that I will be able to install the drawer slides later.

Step 23:

The width of these pieces are 5cm.

Step 24:

Nailed all the pieces together and marked the framework on the MDF, in order to make the drill for the screw, exactly in the center.

Step 25:

I made all the holes perimetrically, placing under the MDF this small piece of plywood, in order to avoid any damage on the other side.

Step 26:

I flipped it over and with a countersink bit I drilled all the holes again, in order to keep the head of every screw under the top of the surface.

Step 27:

Then aligned and screwed the framework in place.

Step 28:

I flipped it over again, and put the piece I made before exactly in the center.

Step 29:

Measured it, marked it, drilled it, countersunk all the holes, put 2 nails to keep it in place and screwed it down.

Step 30:

I put these two extra pieces to prevent the wood from breaking.

Step 31:

At this point, I put in place the piece of wood that I made before, marked it and cut the MDF piece.

Step 32:

You will see later why I did that!

Step 33:

I used these two 1mm spacers and placed them together with the piece of plywood I cut before into the slot under the table saw, in order to mark the center of the wood and put the nut on it later.

Step 34:

I measured the thickness of the bolt and I made a 1cm hole but at first I used a smaller drill bit.

Step 35:

I also measured the nut of the bolt and I opened a hole equal to the width and thickness of it.

Step 36:

...and now we are ready to install the nut into the wood.

Step 37:

Then, I placed it into the slot under the table saw and it’s ready!

Step 38:

Now I measured the length needed and I removed the head of the bolt.

Step 39:

I screwed the bolt into the plastic handle and then drilled them from one side to the other, to make them one solid piece.

Step 40:

I put a nail into the hole, bent it with a hammer and then wrapped it with a pvc tape.

Step 41:

Also, I opened a 10mm hole to the other piece of wood.

Step 42:

Now it’s time to install the two heavy duty 60cm ball bearing drawer slides, on the two pieces of OSB.

Step 43:

I clamped a straight piece of wood in order to install the slides correctly.

Step 44:

I found these hinges in my drawers but for better stability you can use heavy duty stainless steel door hinges.

Step 45:

Then I installed these two pieces on the side of the table saw surface.

Step 46:

Aligned them, marked them and screwed them, with precision.

Step 47:

Also, I screwed these two pieces of the fence together and installed them on the two pieces of OSB with the hinges on, that I built before.

Step 48:

I placed the bolt with the handle and the piece of wood I drilled before and tightened them together with the other piece with the nut, which is into the slot, under the table saw.

Step 49:

I aligned it and then installed the fence on it.

Step 50:

Now, I placed these two bolt safety pins, on each end of the fence, in order to keep it straight and steady, to prevent it from moving.

Step 51:

Because I didn’t have a drill long enough to make the hole directly, I made the right measurements and opened every hole separately and equal exactly to the diameter of the bolt safety pin, in order to fit in tight.

Step 52:

…aaaand… Lets go! Remove the handle, bring it to the edge, remove the bolt safety pins and turn it around to cut the long pieces of wood.

Step 53:

I placed a circular saw under the surface and we are ready to cut!

Step 54:

...and now the long piece!

Step 55:
