[sdiy] Front panel drill hole questions.. (Doepfer/AS)

[Tim Parkhurst]

Hey Jay,

This is a very good point. The mount hole locations are actually what
determines where the panel sits. These holes will also be drilled at the
same time as the component mount holes, so they will be "linked" to the
position of the panel components and (usually) the PCB. Notice that I gave
the center to center vertical distance for the mount holes on the VME card
(4.823"/122.5mm). This is actually the more critical dimension, but most
people will find it much easier to measure .118"/3.0mm from the top and
bottom edges (unfortunately, this will make your mount hole locations vary
with slight differences in the overall panel height. Luckily, this variation
is usually not enough to cause fit problems.)

I guess the basic thing to remember here is (on commercial panels at least),
the edges are sheared (a fairly low precision operation), while the mount
holes are drilled (a fairly high precision operation, especially if a CNC
machine is used).

As far as the Roland modules are concerned, I'd love to see specs or a
drawing or even a sample. Unfortunately, I've never seen any mechanical info
on these, and I don't think a lot of people are interested in building
clones or compatible modules. I like the form factor and overall size
however. Anyway, thanks for the tip!


Best regards,

Tim Servo
