[Jukebox-list] dinking 45s

[Ray Finch]

Although I have never tried this, it would seem to me that you could use a 
1-1/2" circle saw cutter on a small drill press.  The center drill on many 
circle saw cutters is 1/4 inch so alignment shouldn't be an issue. Since 
vinyl is a soft material, I think if you set the drill press to a low to 
medium speed and apply very light pressure a larger hole can be cut 
easily.  Since pressure would be applied evenly inside and outside the 
hole (verses the unequal and heavy pressure that a dinker would apply) 
breakage would be unlikely.

Using a drill press would be important as you will want even pressure on 
the record at all times.  A hand drill would not provide enough control 
and would almost certainly break the record.

For underneath the record, I would put a smooth piece of plywood covered 
with felt glued on.  That should give a flat, stable surface for the 
record to lay on and will prevent scratches.

Just an idea, but I see no reason why this shouldn't work.
