(He said, "Badg-es? We don' need no stinkin' badg-es.") This is only my opinion, of course. At least try it both ways, turntable and armpod both mounted on the same inert STABLE shelf with no viscoelastic mounts vs with viscoelastic mounts.

I hope they will be able to provide their input. To me if I had a tonearm with collar - just preliminary thoughts - but anyway to be DIY - You would need to drill collar diameter holes through both the brass cylinder and the top plate and set the spikes high enough to allow the wires to clear. Drilling the holes is easy for a machine shop. The top plate (aluminum?) just needs to be thick enough to allow the tonearm collar to grip and be tightened - then it can be set down on top of the brass cylinder and secured. This could be done by the DIY. Anything more would obviously require a machine shop. Dear Nandric - I am growing fond of the brass cylinder "as is" and based on what I am hearing am reluctant now to have it taken apart and changed at all. Cheers

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.
