RE: arsclist RE: 78 Rpm Record Spindle Holes

["Audio101" <audio101@xxxxxxxxxxxxxx>]

I understand, but to keep machining cost's down, we have machined the
spindle a few mm smaller then stock, and then supply a machined sleeve
that fits over the undersized spindle for use with normal records.

 To completely machine the spindle off, and then machine another piece
that would somehow join with the flat shaft would be very costly to
make. I can do this if a customer wants, but I am afraid the cost would
be prohibitive.

 Currently my Master Archivist bearing assembly includes an undersized
spindle with standard sized sleeve. And my precision machined thrust
plate assembly with the third screw hole drilled and tapped. And will be
priced at 149.95 on an exchange basis

 Adding a completely machine flat shaft with an insert for standard
records would add at least another 100.00 in machine work to that price.
(good machinist definitely aren't cheap!)

 Most of the problem stems from how to chuck the spindle in a collet and
turn the shaft without damaging the surface that mate with the bearing!
No mistakes can be made here, one slip and the shaft is trashed!

 I want to make a product that archivist will find useful and yet be
reasonably priced. Speak up now, would 249.95 be too expensive if we
could machine the shaft completely flat with the platter and then have a
piece that would slip into the shaft for normal records? I could offer
this as an option.

No spindle is required at all. Friction between the disc and the
turntable 
pad is sufficient to keep the record stationary relative to the table.
Of 
course, for convenience it is useful to have a small spindle; it avoids 
'losing' the disc completely when making adjustments.
