This is either for roger or jokerweb.
Roger your arm looks awsome, i cant belive that from redily avalible items and it appears that construction is very straightforward.

first how do yo attach the inner ring to the arm tube. do you epoxy it or do you have a set screw system.

I have avalible to me hollow carbon fibre arrows. These are lighter and stronger (more rigid) than the alumun. Is there any reason i should not use this arrow shaft.

Did you use pvc flexy rings for any specific reason or was it just avalible. I can get pvc here in the us but have not found a place (or distributer) in the us that sell the units you used.

Thanks for your time.

I am interested in either making ( If not too difficult ) a turntable. or buying a used turntable. Any recommendations? I understand basic electronics and can do some wood working. I am not lookiing to spend over about $400.00 u.s.

Superbe réalisation Roger.

I am not shure if HE is still checking this forum. His last post was a while ago. If not if anyone could answer my questions above that would greatly help. (glue/attchment to pivot, using graphite/carbon)

One extra concern. I was talking to a friend who went through some engeneering schooling and he raised concerns about magnesium. I was told it is flammible when it contacts water.

OUPS,

I didn't look at the date

[Roger Waters]

excuse me, but with my work, I do not have any more time to read the forum.

I used plastic by facility and magnesium because I had some, but all other materials is possible, carbon is better than aluminium for the arm, magnesium can be replaced by aluminium, etc

magnesium and aluminium are flammable in the shape of a cloud of dust, like the corn dust (flour) in a grain silo !
magnesium is flammable in contact with water, but at very high temperature, sodium ignites at a temperature of 15°C


ring the aluminium PVC and tube are assembled "in force", but to stick is better !

Ciao Roger Waters, only to congrat you on your TT!!!

I'm in the middle-land between a working TT and a reassembled one, so... Glory to who succeeded

Ciao from Italy,
