Hey All,

I’ve been considering scrapping the pressed steel extension wings on my oldish Craftsman TS and replacing them with some cast iron. After checking eBay for used options (in an effort to save some money) I noticed that there were several complete cast iron tops, from saws identical to mine, that were for sale for less than $75 (including shipping).

Seeing as how a new extension from a supplier like Rockler, for example, could cost over $100 for a 12” extension do you think it would be possible to add a twin top alongside my existing table? It’d add an additional 20” and maybe even a way to jury rig a router in the blade opening. Plus, it’d have miter slots and I’m guessing all the pre-drilled holes would already be lined up saving some effort there as well.

I should add that my saw has a 52” Biesemeyer fence rail, the majority of which is just dangling there waiting to be put to use.

Is this a strategy or just an insane thought?

Any input would be greatly appreciated.

Not sure if just bolting it to the existing top would be enough support.

I’ve seen extra extension wings added (for example, see this thread at OWWM), but they required some special mounting (not just bolted on), so a table top would probably require a support structure under it. Also, most extension wings don’t have holes on the outside edge, so those would need to be drilled/tapped, and the threaded holes on the additional table would have to be enlarged. But anything is possible with enough creativity.

Cheers,
Brad

I’m a big fan of ingenuity. It’s how I have created my shop. You can create almost anything with the correct tools.

You will definitely need to support it with legs, but as long as there are legs – why the heck not?

You might need some leg support, but it’s worth a shot.

Roger that on the support legs. Seems to be the consensus.

Also, most extension wings don t have holes on the outside edge, so those would need to be drilled/tapped, and the threaded holes on the additional table would have to be enlarged.

As for the fit, I’m assuming that the twin top would have holes in alignment with the existing top (after removing the old steel wing, of course) and that the fence rail has enough holes that 3 or 4 bolts should do the trick as far as getting a flush, secure mount. Maybe even worth reattaching the old steel wing back on to the end of the chain thus extending the top by a full 30” instead of just 20 inches.

See pics of saw and possible extension:

Tops like this have starting bids around $30 or $40 bucks:

There’s allot of holes on the bottom of that table. Might be a way to thread some kind of modified iron pipe to use as legs/support. Hmm.

Got it.. when you said ‘complete top’, I was thinking the main table + two extensions, not just the main table. But yes, the holes should line up, but both will be threaded, so you should only need to drill out one set of holes to allow a bolt to pass through and give you enough movement to align the two.

If you use a TS top with the legs that come with it (essentially a TS stripped of its motor, tilt, elevation, and other mechanisms), that would be like putting 2 TS’s side-by-side, only fastened together. Which is exactly what was running thru my mind when reading the opening post.

If you have not already, check Craigslist for similar TS’s that may be offered for cheap/free. You might score a working TS, which you can use for other operations that you would also do. E.g. a rip blade in one TS, a crosscut blade in the other. If you get 2, that’s 3 things you can do (say, also a dado), or if only 1 complete TS and 1 top only, like you said, make it a router table, which can be mounted in between the second TS, and the one you already have, so it’s supported on both sides.

Now, ya see, splatman? That’s exactly why I love this web site. Throw a question out there and the most creative woodworking minds on the Internet provide the kind of feedback that can really get a guy excited! So much to learn from the experience of others.

I’m gonna consider that option. Considering I paid $100 bucks for my saw (pretty rare deal, I’ll admit) a second saw side-by-side could be a pretty cool setup and not much more expensive.

I’m gonna need to move to a house with a bigger garage!

Thanks, guys.

Next someone will ask if you can have dual saws on the same tabletop set-up. No real reason just saying. LOL
