Time to get the tops mounted to the frames. Originally I planned on welding tabs to the frame and using bolts to attach the two, after staring at it a bit in the garage I decided to use aluminum TRIC-nuts instead (Like Rivet Nuts) as they would be faster and cleaner than tabs.
Here I'm getting ready to start installing the TRIC-nut thread inserts.
I had a scrap piece of tubing on the bench so I installed one of the TRIC-nuts for a test fit and to show how it functions.
Here's the TRIC-nut.
Drilling the hole and installing the TRIC-nut.
Using a standard Rivet Nut Setting tool to compress the TRIC-nut
And BAM....instant threads. Threads stayed nice and centered in the hole, perfect.
Next I clamped the wooden top onto the frame to prepare it for marking and drilling.
Measured and marked center line of the aluminum tubing them marked where I wanted the bolts to be placed. Using a small pilot bit I drilled through the board and into the aluminum.
Next I up-sized the pilot holes in the frame to 3/8" to fit the TRIC-nuts.
And installed and set all the TRIC-nuts in place.
