That is a very akward way to try to make a spoked wheel. DAMHIK
Spoked wheels are correctly made in two halves with the wood rims cut on a bandsaw and the spokes attached to the hub first then the rim halves added. Once together and secured, the wheel can be put on a lathe to true up for roundness. Securing can be done several ways depending on what the item is and the period correctness you are trying to achieve. A lot of research can be involved making your first wheels.
I would not attempt the part you are asking about.
