A Copernican View of the Turntable System

Nandric,

If you buy some aluminium plate (eBay often has various thickness of these at very reasonable prices!) you can make a variety of interchangeable arm plates for the top of your tower(s). The carftsman is therefore only challenged with drilling a hole down the length of the cylinder (55mm in Halcro's and my intended case) and a 30-40mm hole running lower across the cylinder and into the vertical 55mm hole (for the phono cable to run through). That's two holes in total and the weight will be the same as Halcro's.

I already have M6 and M8 taps, drills and footers so no cost there. If not already in possession then, anyone can find these (as I think Chris has suggested) for a very reasonable price from their local hardware store. Three holes tapped for the base spikes; three holes tapped for the attaching armplate. I don't think this is too large a challenge for most on this site. Worth considering I think.

i have been speaking with chris about this thread. he had seen pics of my armpod. you guys are very passonite about this. that's great to see.
my design requirements were to have adjust-ability for azimuth, vta (sra) and flexibility for different arms. the pics show a breuer, but i have already replaced that with a davinci.
i have mounted arms to the armpod that have the wiring come through the pivot point and out the bottom, so a surface mount would not work. i had to use an armboard mounted on a post, on the armpod, to offset the arm. this allows the wiring to exit through the bottom.

Nice solution Corby.
Can you explain how the VTA adjustment and arm height works via the vertical rod?

Corby, That's quite beautiful work. Do you mean to imply that you adjust azimuth by tilting the whole apparatus via the screw-threaded spikes at the base? Don't you think it's important to have the arm base (=the outboard pod) in a plane parallel to the platter?

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.

lewm, i use the 3 thumbscrews at the bottom to adjust for azimuth. it doesn't matter how the armboardor pod ultimately seats, level or not, the azimuth is measured at the stylus using a fozgometer.
