It didnt turn out well, still licking my wounds. Here is briefly what happened…
Made a new jig
After one test screw, I successfuly made one that had reasonable little chipping, I was happy with it.
I actually cut the hub off a reject screw and reused it on this one.
Tapped the leg
Tried the screw, but it binds up after a little bit.
I kept tapping the threads deeper and deeper hoping it would fit but it wasn't the diameter of the hole, it was the thread pitch, and since the leg is pretty thick there are a lot of teeth that engage the nut so it has to be right on. I have no idea why this is happening… The same tap was used for the guide threads in the screw making jig, it should be exactly the same, but its not….
Ironically one of the first practice screws I made with my first jig fit perfectly. I'd use it except I would need a 3" thick chop and it would only have a 4.5" clamping capacity.
Here are all of my attempts laid out in chronological order. The closest ones are the oldest.
Like I said, the first ones I made fit so I still have hope and one more screw blank!
I hope to have good news for you soon.
Thanks for watching and thanks for your support.
