Im thinking about building my own T-square type rip fence. something like this one http://techtalk.parts-express.com/showthread.php?p=1588940 but im thinking about using a piece of extruded aluminum with Tslots in it for the actual fence. How big should the actual fence be? Im finding 1.5×3 aluminum extrusions. is that big enough or should I look at 3×3 or 4×3. http://8020.net/1530-Pop-Up.htm http://8020.net/2040-Pop-Up.htm

I was, just, looking into building a fence out of extruded aluminum.
Here are a couple of websites I found useful:

This starts at pg 2 of the TS rebuild I did. That page is where I decided to work on the T square fence. It is similar to the one in your link. The fence itself is a piece of 44mm x 88mm extruded aluminum that was a leftover scrap piece I scrounged. I have since cut it shorter and have forgone the bearing “wheels”.

BTW…44mm is about 1 3/4” and is plenty strong. I like having the fence low as it is easier to work with. If I need a taller fence I just bolt on a taller face using the T slots.

I think you probably want the 3030, but you can probably make the 1530 work well enough.

I looked into doing this a couple of times. In the end, I decided that the Delta T2 was a better deal.

By the time you have the rails, the extrusion, bearings and a lock, you are at, or even over the cost of the T2 if you use square rails.

The cheapest way to make it however is round rails (conduit or gas pipe) and skate board wheel bearings. It’s harder to figure out a brake for that however.

Jimdaddyo, thanks. Thats similar to what im thinking

brtech. I could get whatever size would work the best. I figured the 1.5 inch width with 3/4 inch sacrificial fences on each side would work, but I wonder if 3×3 or even 3×4 would resist flexing better. I intend to only use the extruded aluminum for my actual fence. the rest will be steel angle and rectangle tube, much like the fence i linked to. I am envisioning a piece of 2×3 angle iron for the head (the part that actually slides on the rail) with a vertical piece welded to the top. the extruded aluminum will then bolt to the vertical piece with 4 or 6 bolts. should be very solid. I will incorporate squaring adjustments much like the one I linked to as well. The main thing im having issues figuring out is a clamping mechanism. Any ideas? Im thinking i could order lever from a fence manufacturer.

Looks like all the steel Ill need would come out to about 107 dollars shipped. Of course Ill check locally to see if I can beat that price. the aluminum for the fence itself will run 50-60 shipped unless I can find that locally as well. figure another 15-20 bucks for odds and ends and ive got a nice fence with heavy duty 6 foot rails for under 200 bucks. looks like i can get a delta t2 for around 175, but the rails are shorter (57 inches) and only 30 inches rip capacity. Im guessing mine at 43 or 44 inches

Yeah, that’s what I thought.

A T2 is $147+$6.50 shipping
http://www.tools-plus.com/delta-36-t30.html

Solid steel, smooth, accurate.

Not worth a DIY when you can get a T2 for less, IMO. A T2 is not a Beis, but it’s pretty darn good.

I understand your length issues. You can pretty easily replace the rails with longer ones if that is really an issue, but then you would be back up to $200 or so.

definitely a good price on the T2. Making me rethink making my own. Although making my own would be a whole lot cooler than buying one

It cost me about $50 to make mine, but I am a scrounger.

So I have been out looking at my saw and fence, and the first thought I had today was that I could make my fence to work with the aluminum rail that craftsman provided me with the saw. Then I started looking at the fence itself. Its almost a T-square design to begin with. the adjustmants to straighten the fence to the blade are on the back side of the fence for some reason, which doesnt seem to work well. All it would take to move them to the front would be a pair of tapped holes and a pair of brass set screws. I would then remove the parts that clamp the fence at the backside and there you have it, a Tsquare fence from the factory one
