While working through my wing spar hole questions with Van’s, I moved on to fabrication of the wing tiedown plates and spacers. It was much easier to lay out the spacers on the bar stock, pilot-drill the center of each 1″ hole, then cut the holes with a 15/16″ hole saw.

Raw spacers

Regardless of what’s marked on the hole saw, they all seem to cut a hole that’s about 1/32″ larger than spec, so using a 15/16″ saw for these 1″ holes left slightly undersize hole in each spacer that were easy to finish to final size with a Dremel tool.

Spacers done

John Sannizzaro stopped by today. He had a brand new tap that was just itchin’ to be used on my tiedown plates. We tapped both tiedown plates…came out fine!
