L-Bracket for t-track

I've got 4.5" between the center of each t-track on my Meteor. I made some L-brackets earlier for my CNC Shark which worked fine, but since that has a full t-track bed with tracks every 3/4" or so I had the bolt holes centered in the l shape, and could easily reach across the L with my track clamps to hold work in place.

This version has the bolt holes offset from the L so you can have track clamps in the same row as the bolts holding the L. Set X,Y zero at the inside corner of the L and you can swap out parts quickly without needing to reset that. My track clamps can reach across the L to hold work down now, which the earlier versions didn't allow.

This forum doesn't seem to allow CRV3D or CRV file, or more than one upload in each message yet. I'll upload the CRV file for this at Vectric.com

The DXF file for the above L-Brackets. You should be able to import it into most CAD/CAM programs. Cut mine from some plywood material a little thinner than 1/4". The holes are for 5/16" bolts.

Here is a slightly modified version that should work with the 4"x4" table insert grid if you have that. I moved the hole centers so they were 8" apart. One insert hole left between them to put a clamp if you want. 1/4" and 5/16" holes to choose from.

Enjoy!
