Worm Gearbox Help

[epanzella]

For an intermitant operation I don't think I'd be overly concerned about the wear rate. Besides it's your first attempt, it's likely it won't be perfect but service-able. I'd say run what you have and just do it. Then you'll discover things you like or dislike. If needed and you dislike it that much, you'll re-do the box or a part and make it better then! FWIW,my point oh two, yada yada yada..

That's what I was thinking. The only way I can cut the worm wheel is by free hobbing so I'll still have the hob to make another one if needed. I'll see if I can scrounge up some scrap brass to cast a blank. Second choice would be cast iron with steel as my last resort.
