A Copernican View of the Turntable System

brad
i only have assembled pics. is there anything specific that you need to know?
also, thanks for the idea of weighting the panzerholz pod. for now, i am using it as-is since i do have another stainless pod half made. it will not have the micrometer in it as the first one does.

Corby, you explained this in you prvious post to Halcro:

the vta is adjusted using the micrometer ath the top of the post, there is a thumbscrew on the side that you would loosen first, adjust the height and then retighten the screw to lock everything solid. the micrometer has a long rod attached to it that extends to the bottom of the pod. this enables the 1" shaft to be raised and lowered as required.

Assembly pics if it isn't a problem would give a better visualation on how it all came or goes together.

Is the brass sleve that the brass AX1 armboard just a spacer for the 1" shaft. Aluminum or stailless?

Thanks,
Brad

Another temp option to a lead ring is maybe some duct sealer that could be formed around the bottom. Duct sealer has been used as a diy dampening on speaker frames. It has a mass to it and can be molded similiar to clay.

the brass sleeve on the stainless shaft is just a spacer. it was easier to machine. i needed 1.18". machining 1.5" stainless would have been more difficult on the small lathe. so i chose to keep the shaft and mating hole at 1" and machine a sleeve using brass to bring the dia up to size.
i do not have any pics of it through the assembly. that would have been a good idea!
the shaft raises with the micrometer as it extends and lowers with gravity, when the micrometer is retracted. there is a light layer of grease between the shaft and it's mating hole in the base.
i could send you closer pics if you would like.

Hey Corby, I follow you. It also looks like the micrometer body was machined to screw into the top of the 1" shaft.

If you ever tear it down take some pics.

much appreciated
Brad

the mic is set into a counter-bored hole in the top of the shaft and held with a small set-screw from the back.
there are many different mic heads available. just check out the starret website to find one that suits your application. they are appx $80.
