T track is the stuff you see in the tops of router tables or drill press tables and things like that. It's used to clamp the fence in place or hold a part in place while you drill it. Feather boards and stop blocks all fit in a T track and you spin the knob and tighten them up so they stay put.
It is a rectangle of about a half inch by about 3 quarters of an inch by, well mine is 4 feet long. You take a bolt with an oval shaped head, stick it in the track at the end and then you can slide the bolt the whole length of the track. To hold it in place you just spin the knob until it's tight. You can do a search for it and you'll get a bunch of places that sell it. May have to order online, but Rockler has free shipping going on now so it's almost as good as going to the store but you don't have to. ----- Original Message ----- From: Tom Hodges To: [email protected] Sent: Friday, November 20, 2009 1:58 PM Subject: RE: [BlindHandyMan] Re: another measuring device: I don't know what that is.

I just use a length of T track and I can lock it by turning the star knob. ----- Original Message ----- From: Dan Rossi To: [email protected] <mailto:blindhandyman%40yahoogroups.com> Sent: Friday, November 20, 2009 11:27 AM Subject: RE: [BlindHandyMan] Re: another measuring device: I see what you mean about needing the nut on the inside, and thus the flattening of the dowel. There are so many ways to construct this device. You could appoxy the nut to the outside of the PVC tube and then not worry about flattening the dowel. You could cut a slot in the PVC, then have a bolt screwed into the round dowel with a nut that would tighten down on the outside of the PVC. My idea for the square block was just a block stuck on the end of the round dowel. The square block would not go into the tube, but it would help to keep the whole shabang from rolling. I've heard of people using curtain rods for this same device. The cam would be difficult, but not impossible to do in wood. Probably easier to just by a plastic cam set. Someone posted a design for a similar device on here, only it was a 2X2 with a groove routed in it, and a flat strip that slides through the groove and could be locked. These are all great ideas for transferring distances. I often use a locking tape measure for the same. So many cats, so many ways. -- Blue skies. Dan Rossi Carnegie Mellon University.
