Alright,
First off, just a couple of quick questions. Is that made in Solidworks and why is it rendered so small?
Now to some suggestions:
-Are you planning to go "live" axles? If not and are planning to go dead axles, the bore has to be .875 or 1.125 due to the fact you have to press a bearing in there with an ID of 1/2" or 3/8".
-Also the sponsor that does our wheels, they like to buy 4" rod stock. Then pocket out the wheel which their CNC lathe and then take it on mill. After that they come back through and shave it down to 3.875.
Example shown
here. When that pic was taken it was 4". So I took it on the lathe the at work and shaved it down.
-How thick is the hub? Since a lot of weight is there.
-How are you planning to attach this to a sprocket (or is it a "Live" wheel). If you are going to attach a sprocket to it. I recommend using a 1.875 bolt pattern which interfaces to all of AndyMark's aluminum sprockets.
-How thick are spokes? I usually make the spokes between 3/16" and 1/4" thick. Also may want to go with spokes like this since
this or increase the contact with the hub. Btw that wheel linked is super thick, it could go on a diet.
-Last question, I promise. How heavy is it?
Great start and continuing CAD'n away.
