Hi All,
I know this may seem to have been done to death, but I do want to build as good a TT as i can ie, much better than my 1972 modified Linn LP 12, with RB 300 Arm, & OC 9 cartridge.
Ive read loads of the threads & am now sort of ready to get going, with a 3 Pod design.
I want to use a 3.5 floppy motor (all the info, pdf's links etc from earlier posts & threads are no longer available) to drive the platter, for which I have in mind to use a stack of vinyl, say 15mm thick, Wood, Ali, to make up a thick dense platter. I have a spare Linn sub platter that could be put to use in some way.
Has anyone used floppy motors with success?
As their seem to be different types available, some with motors at the back some with motors in the middle.
1, If so which kind is best for TT use.
2, how do you control these kinds of motors.
3, what success have people had with sandwiched type platters.
4, & the Altman type bearing.
Feedback would be very welcome
KIS.....with info & pics🙂 PLEASE.

Honestly, keep your LP12 bearing, sub-platter and motor and build the rest. An Altmann bearing doesn't come close to an LP12 bearing in quality, tolerance or rumble.
I wouldn't have thought that an FDD motor would be a good choice to start with. The FDD motor is designed to be stop start with a very light load. The Linn is a fairly heavy load with fairly high inertia and would be required to run for prolonged periods.
thanks for the feedback am going to use the Linn sub plater but dont have a spare bearing anymore, so will have to make one to suit. Am thinking about mag levitation for the plater. ie trying to find magnets from old hdd's.
The idea is to make a TT that can be directly compared to the above kit.
Have in mind a WTA Ill have a wander around the local golf course !
Still need a motor & supply, not sure what to do for the best hear as funds are limited.
