Hi Forum members..

I am looking for help from anyone who has a Sawstop or similar cabinet saw with an Incra rail system..

I messed up on the installation and and ended up breaking a hex bolt head off .. ( I know I am an idiot) I really did not act over aggressive and was very cautious … I got the front rails on fine and felt I just had to do the same thing on the back , but I guess the back had a plate blocking the large bolt from going further or tightening the bracket to the rail…

sort of a disaster for me…

So… I attached the brackets to the main saw top in the holes on each furthest end (not on the iron extension wings) The one that snapped was on the back motor side…

There are many more holes in which to put the brackets now, I can go 1 spot in on the main saw top and have all the brackets attached to the main saw top (just not with as far a space between the rear brackets).

Or I can mount the brackets far apart on the through bolt extension wings..

Can anyone help me on if this is okay to do and will not mess with the accuracy of the saw or fence system,.?

I have tried to extract the bolt with no luck at all… I think the only thing to do is bore it out and re thread it , which is fine..

But… since the Incra rails only need 2 bolts per rail and I have other areas in which to be able to attach the rails I would like to skip tapping and threading the mess up for now and just attach the rails… If I ever switch to a fence system later that requires all the mounting holes I will deal with it then…

Thanks for any help or advice

I don’t have the SawStop (yet) but it is on my wish list.

Having the Incra LS-TS on my Delta I would suggest that you bolt the rails to the saw itself. That way you could remove the extension table(s) if necessary without messing up the alignment of the Incra itself. Had a friend helping me in the shop and he tried to lift and move the saw by lifting on the rails. One went out of parallel with the other and skewed the entire fence assembly. Very problematic to get everything back in alignment.

Thanks for the help!

Yeah I was worried about some possible misalignment issues.. I looked for many pictures and only saw maybe one with the rail brackets set on the wings..

The pic in the instruction shows the rails brackets attached to the main table on the holes at the furthest edges (outside the miter slots) I have the front rails mounted that way..

I can leave the back rail left side to the far outside on the main table but the right backside one is where I broke off the head.. I can move in one mounting hole and stay on the main table still..

Think that will work okay? I am going to take one last shot at extracting the bolt but the thing really is not budging at all..

If I understood you correctly, your problem corner is the back left. That would, in my opinion, be the least concern of any. The “business end” of the thing Incra calls the “positioner” (the threaded rod and the mating clamp it works with) all normally sit on the right-hand end of the saw. In normal use the “front to back” piece that the positioner is bolted to sits far to the right and is held to the front and back rails with threaded knobs…all of that action is on the right hand end of the table. That area on the right-hand end is where the majority of the stress would be for holding the fence in position.

I really can’t see how having the left hand end bolted on at an adjacent hole to the “optimal” hole would make any difference at all. There is an optional “wing nut/knob” at the intersection of the fence and the rails which is more towards the middle rather than the right…but in practice NOBODY bothers to tighten that sucker. The fence is rock solid just from the locked positioner. The rail fasteners over on the left end are mostly just there to hold the rails up level with the table…not so much for keeping the fence rigid.

If it were me…I would forget about it and sleep well tonight.

BTW, you will really enjoy working with your Incra fence. (and your saw stop too)

BTW, I also purchased the larger of the two Incra router table tops. I cut it roughly “in half”, and mounted the business part of it off to the left of the left wing using angle-iron pieces. Did similar with the other half of the table to extend the right hand end past the wing of the saw stop pcs.

The whole thing works beautifully! To use the TS/LS with the router table, it takes 10 seconds to loosen the knobs and move the whole thing a couple feet to the left. About the same amount of time to move it back to table-saw position when I’m done, and due to the way the rails are designed, it drops down perfectly adjusted to where I could replicate a measured cut to within maybe 5 thousandths with zero setup or alignment or any tweaking.

Brilliant piece of engineering, that Incra system is.

In theory you can put them in the extension wings and also in theory the farther apart the rail brackets are the stronger the system will be. But if the edges of your extensions aren’t milled perpendicular to the top, your rail tops won’t be parallel to your saw table top. It will put a twist in the Incra rails when you tighten them up. I know on my Unisaw the extension surfaces are only cast while the table sides are milled. I hope this makes sense but I’d keep trying to extract that bolt if it were me.

JeffP.. are you saying you were able to get the Incra router setup on the left side of the PCS ?

I believe Incra says it is only available for the right side?

I have a 17” positioner and router set up.. I debated doing a combo set up (very short on space) but I do not like the router table on the right side…I don’t like the “feel” of the router trapped there… But if I can work off the end of the table saw with the router I would do it.. Sell my 17” Positioner and use my stand in my basement for my next tool.. I LOVE my Incra router set up and it is why I went this route with my table saw set up…

Getting the bolt out isn’t gonna happen… I am down to moving the bracket in the rear left (motor side back) in one mounting hole on the main table or tapping and rethreading..

and with the 2 last replies that leaves me at 50/50 has ha…

Thanks for the help though and any advice is welcome…

Yes, I put my router table on the left.

I think the trick is that Incra support is only thinking of REPLACING the left wing of the sawstop pcs with router table, and that would not work because of the motor.

Instead, I put the left-hand cast iron sawstop wing on there the normal way…and then put the router table extension to the left of that. It is well past the motor housing. I would have to lift my router out to open the motor door all the way, but that is extremely rare.

so you say you used “angle-iron pieces”

are you saying almost like shelf brackets that you mounted onto the end mounting holes of the Sawsytop rail system?

If so did you just use one through built washer and nut in the front and then the back ?

Thanks.. I actually gave up on the idea of the TS router combo but this is shedding new light…

I actually bought the 17”positioner for space but after having it sort of wish I got the 25” mainly because it was only 30$ more.. Though I have not needed it..

What size ts-ls do you have? Are you able to get 25” router capability out of the set up?

I only have the 32” no space for the 52” unless the wife lets it go in the basement (read, not possible)

JeffP, could you post a picture or two of your PCS with the extended left side router table setup? I’d really like to see how you did it.

I just had the exact same problem when attaching the Incra TS/LS rail brackets to my new Sawstop PCS. The 5/16-18×1-1/2” bolts worked fine on the front of the saw, but are too long for the rear threaded holes because they hit a part inside the saw cabinet, so the bolt breaks off! But I was able to remove the broken 5/16” bolt with a screw extractor. WHEW!

I am posting in the hope I can save someone else the same grief: DON’T USE THE 5/16-18 X 1-1/2” BOLTS SUPPLIED BY INCRA! SUBSTITUTE 5/16-18 X 1” HEX BOLTS PURCHASES SEPARATELY INSTEAD!

Given the number of Sawstop PCS saws being purchased, you’d think Incra would include 5/16” x 1” bolts in the hardware pack, and a note in the owners’ manual to uses the 1” bolts, not the 1-1/2” bolts, with the Sawstop PCS. They could save some purchasers some real pain.

Have your say...
