Wow! This Is Getting To Be Like A Regular Job.
Nah! not even.
We do this stuff because we love doing it.
The first project was to make the side stand for the Panther work in some sort of way where it would hold up the bike without bending something else.
After some head scratching we decided on using what appeared to be the rear sidecar mount weldment.
The side stand which came with the bike was man enough for the job but just not well attached.
I came up with a bracket design to attach to the existing stand. So after machining the stand I took both the stand and the bracket to JB, my favorite welder and had him join the pieces.
That crappy brazing you can see was part of the original set up and not the work of JB.
Once back at Sheddington, I set about machining the bracket to fit the bike.
As there could be only one bolt to make the attachment, a method to prevent rotation on that bolt was needed.
I decided after a lot of cogitation and perhaps one or two Buds to machine a slot register in the bracket.
The tough part was making the mating key register on the bike. To make this a little easier, it was decided to make a gauge bolt.
The threaded hole in the sidecar mount was 3/4-20 Whitworth form. (Yes, about as common as rocking horse shit)
I bought a couple of bolts from the local Ace to use as starting stock.
OK they're crap bolts and ungraded but a 3/4" bolt of almost any kind will hold the side stand.
I made the gauge bolt and after a couple of tries got it to screw in to full depth.
Then two of the flats were machined to give a dimension of 1" AF.
The bolt was screwed in and the machined flats aligned to be vertical.
The mount was ground to match the bolt.
This is the bracket after the slot was machined, as you can see it was within 0.001" of the desired dimension.
Here is the bracket mounted to the sidecar attachment point.
It was necessary to make a standoff for the muffler to prevent the stand from impinging on it.
This was the first pass at it, which ended up being just a little too long.I shortened it up and now it is just right. That piece will be found by some industrial archeologist in about a hundred years and will have him or her scratching their head. "Crazy people back then, this thing is BSF on one end and UNF on the other"
The proof of the pudding, as they say, is in the eating thereof.
Here is the stand in place and after a bit of judicial heating and pounding the lower end was made to sit flat on the ground.
Thanks to Jimmie with the big hammer and the torch.
The next project in the form of a short video is about the manufacture of the orifices required to make a carb sync tool work.
All the best,
Norm
