    BT3000 tall rip fence

    09-12-2021, 07:58 PM
    I have had a tall BT3000 fence for a number of years, I should have used it a few days ago but I didn't because it was too much trouble, And I paid the price as the tall item was a little unstable and I had a hard time controlling it as the two pieces separated and wallowed out a bigger kerf than I wanted at one place.

    Anyway the BT3000 tall fence is generally held on by the T-slots in the side of the rip fence. This is compounded by two things... you need the BT3000/3100 specific T-bolts/nuts. And not only that but you need different sets of nuts/bolts for the left and right side of the fence.

    My old fence had both sets of holes and recesses - yes to add to the difficulty you need to recess the heads of the bolts and nuts to not protrude, another complication needing the exact right sized length bolts.
    And even though I had all those, you have to partially disassemble the rip fence to slide the nuts into the grooves.

    Now I'd seen and heard of this before there is a way to make a fence attachment using what are called fence clamps https://www.sawdustzone.org/forum/vb...arison?t=49791

    I use the ones from Rockler which are very nice and have some other uses.

    So I took my old tall fence and modified it with some slots for the fence clamps to fit. I made elongated holes - two 1" holes and a jigsaw between them. Honestly, it would have been simpler to drill a 2" Forstner or hole saw and be done. But I decided I wanted elongated holes. I rounded over the edges so there's no chance of work catching as I feed it. Don't forget you need a 3/8" hole from the bottom edge of the fence to reach the opening. Good job for a drill press. as its longer than 2" needing to be centered in a 3/4" plywood.

    I checked with a combination square and protractor and the fence was almost perfectly perpendicular to the table saw table.

    One thing I did for the BT3000 specific was to add a couple of 1/4" dowel pins to ride in the slot in the front (left side I normally use) of the rip fence to position the fence 1/16th inch off the table so the fence does not drag and the rip fence positioning works as smoothly as normal (the pins are centered 15/16ths from the bottom of the fence.):

    Some suggested measurements for the holes. Visio-Detail drawing Tall rip fence.pdf

    I used a 24" x 9" piece of 3/4" plywood.
    Attached FilesI just did a little playing around. If I was to do it again, I would just drill a 1-3/4" to 2" hole with the bottom edge 2" from the bottom.
    That's enough to get the Rockler clamp pin in the hole.
    Nothing wrong with 1/2" wide slot if you want to, but leaves just 1/16th clearance if your 3/8" hole is perfectly centered.

    But 1-3/4" hole so much easier than the oval and you're not going to have any issues with support from the big holes in any conceivable item on the saw. shown below is a 2" hole and a 1-3/4" hole in a piece of test scrap:

    One of the best purchases I ever made for my drill press is the $36 HF 16-pc Forstner set 1/4" to 2-1/8" diameter. https://www.harborfreight.com/14-in-...-pc-62360.html


    In my my PDF drawing I put the bottom of the hole a little higher... to make the screw foot of the clamp on the ridge of the back side of the rip fence and not end up between slots. What I have decided I will do in the future is to use a 2" high x 24" long piece of thin wood strip to protect the back side of my rip fence.

    A user in the Rockler product reviews suggested using a soda bottle plastic cap to cover the end of the screw foot to make it less likely to damage "non-marring" stuff, I wonder if that works or makes it too slippery. Another user suggested oiling the screw-screw foot joint to make it smoother.

    • Extending rails/rail profiles
      by LCHIEN


      I am finally going to use my BT3000 extension rails.
      My objective is to have some easily attachable rail extensions rather than a full time wide BT3000 using two full rails taking up a lot of space and requiring table support under the right side as many do.
      I just want some wider support but not to do full 4x8 sheets of ply... if I need that, I'll break the sheet down on some sawhorses with a circ saw and some guides.

      I think I am going to cut my extension...

      by Dedpedal
      One of my early attempts at making mallets had me thinking how badly things could end up if my piece got away from me while cutting so I came up with this little jig sled to secure my work while cutting a 30 bevel on the end of the head.
      A simple flat piece of 1/2” birch plywood with a fence squared to bot the sled and blade with gussets on one side and push type toggle clamps on the other. Right now I have to manually place the stop block with double sided tape but working on a t track...

    • LarryG's Dual-Width Extension Wing
      by LarryG
      Around the middle of 2006, I came up with an idea for an extension wing for my BT3100 table saw that solved some particular problems I had in my then-shop. The design worked well, and about a year later, on May 6, 2007, I started a thread on the old bt3central.com discussion forum and shared my design with the other members.

      I called it the Dual-Width Extension wing, and you can see it here:

    • Shopmade sanding blocks
      by LCHIEN
      Whilst cleaning up I found an old BT3central post by ejs1097 I printed out from a while back. I had forgotten about it. I made some changes and whipped out a few in a couple of evenings. What I liked about them was they hold the sandpaper tight and snug, the bought ones the paper works loose and sags and gets caught and tears. Also easy and cheap. Also has a square end for sanding into corners and a radius to do curves. I did modify the block so it used thicker stock (easier to hold) and put the ...

    • BT3000 x 2 Frankensaw
      by rickschuster
      Thanks to all of the great examples I saw on this forum, I decided that buying extension rails for my BT3000 would be silly when for less money I could find a used BT3000 to add to mine. Less money, and in addition to the rails I wanted, I had another complete saw, router table section, fence, sliding miter table, etc., and a far more useful saw overall. I really love some of the beautiful bases that some people have made for their Frankensaws, but I wanted to get the saws functioning to use for ...
