At some point back in the fall I got it in my head that I wanted a sliding table attachment. Haveing a small shop I knew I didn’t want rails to extend out past the feed side of the saw. So I figured that it should be possible with full extention slides. While searching for ideas I saw the sliding table at www.ibuildit.ca
http://www.ibuildit.ca/table-saw-1.html

That was pretty much what I needed. The only thing I didn’t like is that that one doesn’t pass the blade. So I jointed two full extentions together top to bottom. A set of 28” slides provide the feed side travel, then when they finish their travel the 24” outfeed take over and I am able to pass my material completly past the blade. A pair of slides on the top and one on the side keep everything from shifting and keep everything running true.

Looking good. Is there any noticeable lateral deflection?

Another option is to use two way slides. They consist of only two sections (less slop), extend 50-70% in either direction, and available up to a meter long.

Even more serious approach is two directional telescopic slides such as Rollon. Those are not your ordinary cabinet slides. They are made of cold rolled case hardened steel and designed for loads of hundreds kilos to over a ton. While it is overkill load wise, they are precision machined and have virtually no lateral play and are silky smooth.

I miss my slider. I had a very heavy, overbuilt sliding table on my Unisaw for 20 years, about 10 years ago a friend sat on it and broke right off the side of the saw. I’ve been thinking about getting the Excalibur version but I like this construction you came up with. Thanks so much for sharing.

Viktor, I find that the slides mounted in the virticle possition on the side really takes away the lateral deflection. I find there doesn’t seem to be any.

I had thought of the two way slides, but at the time I started this I couldn’t get ones that I thought would be long enough locally. The directional telescopic slides sounds interesting. Until you posted I had never heard of them before. I’ll have to look into them. They might be handy for future projects.

Earl, what did you do with the pieces of your “friend” after you ripped him into small pieces on your Unisaw?

I’da feed him to the dog….. ;)

Jonathan, I had thought the same thing too. It comes up on the link that I posted with my discription. He said it wasn’t a problem so I’d thought I’d give it a go. I find that it isn’t a problem either. I keep it brushed down when I’m done. Also, when I’m not using it, the slides are concealed under the table and that seems to be enough to protect from airborn dust of ripping etc…

Totally cool! I have a slider but I’m going to do this on my next regular table saw for sure.

Well now, I just notice that 3rd slider on the side. That likely helps a lot with the directional stability of the whole thing (lateral slop). VERY nice. I was thinking about getting the plans for that from ibuildit.ca a while back. Now maybe I will.

Shawn_s, you can look at these (look for two way models):

http://www.rollon.com/english/prodotti/TelescopicRail.htm
http://www.chambrelan.com/EN/product/R53/telescopic-slide/partial/extension/steel/
http://www.gsfslides.com/en/category/telescopic-slide.asp
http://onlinecatalog.tpa-us.com/category/ballrace-telescopic-linear-slides-ball-based-

Rollon is probably the industry leader. The down side is they are very expensive, several hundred $$ for a pair of 3 ft long slides. Chambrelan and GSF are cheaper. I got pair of smaller Rollons on e-bay for ~20% of the original price and planning to build a small slider for router table.

I like what this guy did:
