I finally got to see the end of a Sprint Cup race this year, on Wreck-Free Sunday

And congratulations to Happy Harvick on his victory in Phoenix. I don’t know what it is about Kevin Harvick and Phoenix, but it seems the guy can’t lose there, even (especially?) when he doesn’t do well in practice getting set up for the track. They get it close with springs, shocks and swaybars during practice, then dial it in perfectly during the race just in time to win. I mean it’s uncanny how that happens.

In other news the raw stock for the various frames for the Mini Sprint-T just shipped, and is expected to arrive on Friday. I got 0.060″ square and round stock and some 0.01 sheet stock that will also be used to build the trunk besides building a lot of the frame. In scale it’s 0.25″ thick, but it’s the thinnest sheet stock you can buy and barely stands up to handling as it is. The other stock is 1.5″ square and round in scale respectively. I figured out how to do the bending for the round stock using a butane torch someone gave me years ago, so that part of the building problem is solved, now I just need to get some butane to fill it with.

Anywho getting back to the bending and getting everything the right size. What I will be doing is clamping one end of the stock on a form that is the right shape for the inside of the bends for whatever part I’m building and applying pressure at the first bend, then point the lit torch at the bend and lower it closer to the stock until the stock starts to bend, stopping and holding that distance until the bend is completed, removing heat and hold until set, then move to the next bend. I just need to find out what the inside radius for a 1.5″ tube on a mandrel bender to make the forms to bend the stock around. I think heavy paperboard or maybe balsa wood. It doesn’t have to be very thick, 0.060″ is just under 1/16“.

The round stock will also be used to make the exhaust headers for the SBC version of the Mini Sprint-T, so I really hope I bought enough for 3 frames and some left over. Otherwise I’m going to have to spring for another pack of product. Actually I will anyway because I don’t have anything to make the front axle from, so I will order the correct size for the axle, which is slightly large for the exhaust headers. So, that will be my next purchase for the Mini Sprint-T. Plus the other stuff I would need to model the exhaust headers.

It’s late now and I have to get up early tomorrow for “stuff”, so I’m calling this to a close.

PSA, Opus
