drilling out Proctor spoked wheel hubs?

Thread Starter

The Proctor wheels come with a 3mm hole and I've drilled that out to 4mm. But how much bigger can the hole be made. The hub looks like it's much wider. Has anyone drilled this out to 5mm...or even 6mm?

My digital caliper shows it to be 6.45mm. So let's say a 6mm axle would work. Almost scale on a 1/6 scale WWI aircraft. The nylon inserts seems a very tight fit.
