Milling Machine Handwheels

When I bought my machine the handwheels on the X axis were crap, no idea what happened with them but the hubs seem to be from a real handwheel.

So I'm making new ones. I started with some 1/4" plate and cut out a pair of "Mercedes" emblems about 7" in diameter.

From here I got busy building and forgot to take more pictures but I cleaned the frames up with the rotary table, laminated some cherry wood for the wheels, epoxied and riveted the wood to the wheel frames and here is the result. I reused the one hub for the left side of the table and the right side is on the hub of the power feed.

I applied a couple of coats of Teak oil for a finish and am happy with the way they turned out. The picture with the handwheels, old and new, also show the start of the handles that I'll turn down and give some shape to them. The rivets are from Lee Valley and give them a steering wheel look, like I stole them from some kids gokart lol. Hopefully I'll get the handles done before the new year
 
Very nicely done Mike. Metal spokes, brass rivets and wood gives them that certain elegance. Reminds me of classic cars or boats.
 
Wow! That’s almost too nice to use!

While on handwheel, using autodesk inventor I was able to design a balanced handwheel including the handle. It use 1? triangular spoke. My Standard Modern lathe uses that design. I don’t know if it can be done in Fusion or not.
 
When I first installed the PF, PeterT mentioned that when using the PF there is a chance of getting whacked by the handle of the hand wheel but that won't be an issue here.

Picture?
 
Designed, NOT made LOL
I likely did it the hard way. Inventor would calculate the centre of gravity and I manually adjusted the dimensions of the triangle piece to get it in the centre. I don’t know if fusion has the COG calculator.

Here’s a picture of the SM one.

If it was to turn it could possibly affect the settings during a operation.

Got it, I was thinking more along the lines of higher rpm related balance. My table takes a lot more effort than just the weight of the handle to turn the screw.
 
I can see the need for the balanced wheels on something that sensitive. Sneezing close by would be enough to jar the wheel.
 
I think most lathe handwheels and ball handles are balanced. Whether it makes any difference I don’t know.
