Topic tags/keywords: twin ts siamese ts table saw modification

A while ago I was working on a project that required me to cut a number of dados at different stages of the build. One of my least favorite shop activities is changing TS blades and this project that inspired me to try to build a better mouse trap.

I’ve spent the better part of a month watching the local Craigslist for an appropriate saw to ad to my cabinet mounted contractors saw. I found it a few days ago, and picked it up tonight (it’s in rough shape) and now I need to figure out how I’m going to go about mounting it.

So far, I’ve only found one picture (seen below) of a pair of saws configured side by side and I guess I’m hoping that I’m not the only crazy person out here and that one or more of you good folks has “been there, done that and has the pictures to share”.

Interesting idea. I assume that you are going to leave one saw set up for dado cuts only. I would love to have the room to do that as I like to cut dado and rabbets on my table saw. I can well understand about not liking to change out the blade. That should be a real time saver and well worth the money you spent on the saw.

Before I built my new shop last year I was using a bosch mobile table saw. When the shop was built I bought a cabinet saw but still had the smaller table saw for 3 or 4 months before selling it. It was convenient at times but after using the cabinet saw the bosch felt like a toy, and space became a premium as I bought more tools for the shop.
Two bigger table saws are a great idea if you have the space.

I notice the picture you posted used a couple of tables from other table saws rather than table saw extensions or just a wooden extensions. That looks like a good idea for a two-saw setup. It will add weight and extra miter slots. I see old Craftsman table saw tops on the bay all the time. Although a lot of people rail about Craftsman quality, I don’t see how they could screw up a cast-iron top (much :).

Should work. One fence for the two saws and you just lower it when you don,t need it. Can you afford the space instead of a mobile second saw?

So long as all of the dado’s are the same size I think that is a great idea and time saver.

I guess the only need is to satisfy your OC, eh?

Professionals only buy the tools they need. We hobbyists buy the tools we want.

The picture of the saw I posted originally is not my set up but that of another blogger on a different forum. I posted it as reference only.

My need to cut ¾” dados and rabbets of various sizes is pretty much on going so the time savings although not significant in the long term is secondary to the abeyance of the aggravation suffered during blade changes. I suffer inconvenience poorly.

My setup (although still conceptually fluid) will likely consist of three of the four cast iron wings, one at each end and one separating the two TS tables and my 36-T30 Delta fence. The whole thing will be no larger than it is right now so space won’t be an issue more than it already is. I plan to mount my router into my workbench (I must have a lift, another source of annoyance) and hope I live long enough to actually get all this stuff done. Maybe, once it’s done I can get back to building some furniture. 

This 1st picture linked below is of my original saw prior to actually mounting it. In the picture it’s just sitting on the cabinet. Below that you can see the saw as it ended up in the foreground with the router wing extension (poorly thought out) which I will be nixing.

Thanks for all the input.

Looks like the kind of setup you would have to do something that begins with “Hey, watch this!”.

I saw this setup at the woodworking show in Chantilly, Va. and just had to take pictures. The vendor had this setup for shipping but it may give you an idea or two.

i would think the vibration on that would be killer unless you can get both saws almost vibrationless
