My wife would like a tea cart. I have plans for one that calls for 6 spokes in a wheel. I would like to use 5 and have been struggling with figuring out the spacing for the hub as well as the outer wheel. Is there a formula for this that makes placement easier? I tried Sketch-up but had absolutely no luck there! Could be because I don’t know how to use it that well. Maybe there is a plug in for making spoked wheels??? I haven’t found one.

Any help would be appreciated.
Thank you
Bill

Hmmmm, well I’ll give you my suggestion.

What I would do is measure the inside circumfrence of the circle and divide it by 6 and that will give you the distance from center to center of your spokes along the inside of the wheel. Then just mark the center of your spokes on the inside and outside and line them up.

Sounds like it should work.

Measure across the centre of your longer circle. (The outer wheel) This is the Inside DIAMETER of your wheel.
Diameter x 3.14 = circumference.
Divide your circumference number into 5 pieces and mark the centre of each of your spokes.
Do the same for the hub,
Example: Your wheel is a 16” diameter.(inside measurement )
16×3.14 = 50.24 or 50 1/4”
Divide 50 1/4 by 5 =10 inches O.C. (The number is really 10.048.)
Yeah I know, those silly decimals.
1 /16 inch = .0625
1 /32 inch = .03125
Okay it is: 10 and more than 1/16 and less than 1/32 inch. (10.048)
Assume your hub is 4” diameter
4” x 3.14 = 12 1/2 inches
Divide that by 5 = 2 1/2” O.C.
Now that we have all these numbers and totally confused, I sure hope your wheels is round !!!!!

Yep, divide 360 by the number of spokes. This will be your angle.
