It’s track day!!! part two
Showed this last time but just wanted you to be able to see the difference in the jig.
Drill the one finger then flip it and drill the other. [9/64 drill bit]
Then started the other end using a 1/64 larger bit I’ll show pictures why later.
I drilled a little passed center then flipped it over and drilled the other side.
I added a board under the jig so the tread wouldn’t slip down under load
I first drilled all the small fingered ones as in the first jig then drilled about 20 with the second jig and tried them out and they were ok but they need to be able to turn around a 2” wheel and these wouldn’t come close.
So I sanded a 45 degree on one side of the small and large fingers this made the clearence needed to bend nicely.
I made a jig on my sander to do this.
First set sander at a 45 degree.
I placed a fence parallel to the sanding disk a little bigger than the tread then brought the end at the out side of the wheel in to a distance I wanted for my 45 degree cut.
Now I turn on the sander and place a tread at the loss end and slide it toward the out side, nice sanded 45 degree.
The pictures do a much better job of telling the story.
But I still have a problem???
The treads bend but head to the side just a bit plus when set down they sit up a little.
You can see in picture the walnut or dark treads have been fixed but the lighter ones show where it needs work.
So I went back and drilled all the big finger treads with a 1/64 bigger bit and all is fixed.
Now they bend way more than enough and are straight.
They wiggle just like a snake.
Here’s a shot of the walnut with the bigger hole and the mahogany before drilling them out.
I started on the track frames and spacers but no pictures so will show that next time.
You have to remember one thing on these how toes.
There’s a hundred ways to do any thing you just have to use what you’ve got on hand.
This is whats working for me with my cheap Harbor Freight tools.
I used to have a shop full a tools but when I retired I thought I was out of wood working and gave away all my wore out tools. lol
Thanks for checking in.
-- There's a hundred ways to do anything, alot depends on the tools at hand.
