Good advices for a newbie (threading tools lathe)

[C-Bag]

I'm glad you joined the party PJs and was helpful to Stefano. My ramble into my lo budget ancient hi fi days didn't do much to help his quest for audio nirvana

With your truly impressive background PJs do you think it's even necessary to have the guide thread onto the driver? Wouldn't a slightly tapered press fit with a set screw give as good acoustic coupling? Of course this would mean machining off the treads of the driver and then fitting the guide appropriately. But for my limited threading abilities this would be easier.

In my mathematically impaired brain I've wondered if it was desirable to excite the guide, or to have it dead? Inquiring ears want to know....
