Default "Rule" or "Scale" for t-slots?

I'm looking for a ruler and mount, right-to-left that will work with or mount to t-slots in aluminum extrusions. What I'm looking for is a 48" scale that will work for fences and jigs using standard aluminum extrusions. Reason for this type over a self-stick rule would be to re-zero/calibrate for different settings...

Rockler says they have ones that will fit "universal t-slots"??? I guess I'm not real up on the t-slot terminology of different t-slot types these days. I'm figuring that is not for the 1/4" t-slots that are found in stock type extrusions.

Afterthought- Maybe I probably should have posted this to "Jigs and Fixtures."

You mentioned 'self stick'. Kreg makes a very good aluminium 3m tape measure that is designed for their t-tracks and top tracks. It's a standard half inch and also fits the Incra flip fences.

They make both a left-right and a right-left version. If you want tapes that aren't self sticky, then look at the Incra offerings as they are designed to slide when zero-ing out a jig.

Hope this helps.

Thank you George, but not looking for an adhesive rule.

Hilton, thank you. You are more on track. The Incra replacement parts miter gauge "scales" are more what I'm looking for, but I would have to make something to adapt it to an aluminum extrusion. Dare say that $50+ for their "Incra tracks" would be adding too much extra besides just the ruler. The Incra scales are just $2 per 16" section...

Hi Mike - if it helps any, I just measured the tape in my Incra miter guage and they look to be 31/64" wide. You would need the tape to fit pretty snugly to keep it from moving around after it's been zero'd.

The problem with experience is I usually get it immediately after I need it.

So, just a hair under 1/2"... Hmmm. Thinking it's mounted in a slot. If I use a small (size #4 or #6) thumb screw, that would lock it in. Depending on how thick the scale is, I could probably make an adapter with a slot cut for it with a router t-slot bit or a key hole bit on a router table. Then on the opposite side, route a T-rail to slide into the t-slot of the extrusion (cut out for a couple t-nuts to secure).

Sorry Mike - I should have anticipated the next question
Mine calipers out to 0.010"

Mike,

Is this the type thing you're shooting for? (below is an 18" section)



The rule portion slides so it could be calibrated to a specific point.

(one note: the rule is in sections that overlap so the adjustment might be a little more involved that just moving one piece.)

If this fits the need Amazon has a range of sizes from 18" up to 48" at a cost range of ~$13 to $20 with Super Saver Shipping. You can get the dims on the Incra site.
Amazon.com: incra t-track plus

GCG

P.S. The rule is "0" at the center.
