I would expect that the crank knobs were as shiny as the other interior plastic parts.

Again, I want to express my desire to get some of theose knobs from you if you decide to go through with production. Then the interior will look great except for the creosote staining on some of the door panel areas.

That's some awesome work there, CPR. I'm sure there's a small market for these, but you would have no problem selling extra stock. Can't wait to see the finished product.

Thanks. Believe it or not, that took less than half an hour. It's amazing what you can do with a $20,0000 piece of CAD software and 15 years of experience using it.

Those escutcheons look very nice and i could use eight of them in the 53 sper wasp color [BLUE] should you decide to reproduce them. keep me in mind

If the knobs work out the way I hope they do, the escutcheons will be next. I'll let everyone know when I get to that point. I'll probably have to get a sample from you for the color but that's a while in the future.

I'll let everyone know before I do this to figure out how many to make. We still need to come to a consensus on the size.

I had a few made up this weekend as a test and I wasn't really happy with the dimple. I need to get with the guy who made them to see what can be done to improve the shape. After that, I need to decide on material and then paint and finish.

RL Chilton

If you are casting these, keep in mind that an additional step could be instituted in the manufacturing phase for the "correct" dimple, which, would be to chuck the knob up in the lathe and face the knob with a ground cutter to the desired profile.

Might even be simpler than that, with the correct size drill bit (again on the lathe), and followed by some simple shaping with sandpaper and polisher.

Just thinking outside the knob, here . . .

Chris,

I think you need to decide yourself what makes you happy. I don't think that anyone will complain about what you come up with, it will be far better than what most people have on their car.

Agreed!! Don't sweat the small stuff, Chris.

Okay, Chris;
Here are the '50 Pacemaker cranks I mentioned on the phone. The better knob in the picture measures 0.77" tall, 0.735" OD at the big end, 0.39" OD at the small end, and has a 0.1" dish. Dish OD measured 0.55". As you can see from the picture, the plastic is pretty deteriorated and this may explain why my dimensions are a bit bigger than the smallest example you had. Dan said these knobs were in really nice shape until he took the car to a body shop to be painted. He couldn't believe these were the same cranks that were in the car when he picked it up a couple months later.

Here is a new picture based on the latest dimensions:

[attachment=9181]threeknobs_2011-01-07.JPG[/attachment]

The one on the right is from the earlier dimensions, the one in the middle is from the dimensions in the last post and the one on the left is halfway between the two.

Any preferences or other suggestions?

RL Chilton

I like the one in the middle.

onerare39

I would vote for door number two... the middle one.

middletom

CPR,
I also think the middle one appears to be just right.
