This whole project (jig plus template) is awesome! I did my templates with 9.2 mm holes and used a 9 mm aluminum tube and it fits perfectly.

Great tool. I made table made of 2 elements and another one made of 10. Not giving 5 stars because the puzzle connection do not match 100% and I had to grind or force.

I use 8 of them on my LowRider 4 table and they are quite versatile

Awesome. really what I needed.
