Re: Machining a funnel
It's a pretty simple piece to make if you have the tools. It could be done in a mill, but a lathe would be easier. Might be a good excuse to buy a lathe Carbide would pretty much require an EDM, not common in the home shop. But annealed tool steel machines easily with home shop tools. Some O1 or A2 drill rod would be my starting point. You can harden it with a torch.
For small parts like that, you can easily turn your CNC mill into a CNC lathe, Just use the spindle to hold the part, and hold the tool in your vice. I used to do this occasionally before I bought a CNC lathe.
An alternative would be to have the part made by a commercial vendor. Dayton Lamina might be able to make that at a reasonable price, they do stuff like that all the time. https://www.daytonlamina.com/sites/d...Kommercial.pdf
