Thread: Machining cam lobes
19/08/2011 14:30:48
I met a guy at one of the shows a few years ago who had made a kind of pantograph type arrangement for tracing the outline of a full-size cam and moving the scale cam against the cutter in the same shape.
 
<pause for a quick bit of googling>
 
The guy's name is Invar Dahlberg, the model was a Mercer Raceabout, and the tool was used against a grinder - see http://www.craftsmanshipmuseum.com/dahlberg.htm

Thread: Forming Wire Wheel Rims

Thanks Jason, very helpful.

Thanks all. Yes, I am familiar with Gerald Wingrove and his method of making wheels, but I was hoping to use the same technique as the originals. I guess it's a bit ambitious to think it might be practical.
 
So, does anyone know a good source of thick-wall Aluminium tube, say 4"OD with a wall thickness of 1/2 inch or so? The prototype rims are quite deep, but I suppose I could make them from 2 concentric rings glued together?

I'm thinking of making some 72-spoke wire wheels for a model car, they will be in 1/4 scale. The prototypes are 15" dia with 5" rims, so the model rims will be 1.25 wide.
 
I'm thinkng that I ned to make some kind of rolling device that will form the necessary profile into a strip of brass sheet and put a curl into it so I can solder the ends together, but beyond a vague notion of sets of shaped rollers I haven't got much of an idea how this should be done.
 
All advice gratefully received...
Thread: C A D for Mac

Bootcamp is fine, if you don't mind rebooting. On the downside, you don't get to be able to use any of the fancy interoperability functionality like being able to cut and paste between Mac and Windows apps. With Snow Leopard and 8GB RAM I don't find any performance issues.

If you want to carry on running TurboCAD for windows on your Mac, you could consider buying some virtual machine software like Parallels, this will let you run a copy of windows on your Mac. You'll have to have a legitimate copy of windows, as well.
