You'll have to make a new stalk. It has the stub inside and I can make a pattern of a good one for you.
So how about this? I can loan you a good stalk. If you reproduce a batch of stalks, give me the original and two repros back, and you keep the switch. About a dozen should satisfy world demand.

How about it John? Seriously, I don't need money and this needs to get done, I'll never get to it.
