I am assembling a 10" F6 in a reconditioned Parks tube-11 7/8" ID. The
surfaced has been nicely roughed up (walnut shells) and blackened. I have
prepared a Baffle to mask the mirror edge, but am not sure I should use it
given the discussion of baffles mucking up the airflow.
The baffle was made from black ABS plastic, roughed up with a sander and
then painted with Krylon Ultra flat black paint. The inner edge has a 45 °
bevel. It has an ID of 9 3/4" and an OD of 11", and is designed to mount
on the top of the mirror mount 1/4" in front of the mirror surface. It
will mask the outer 1/8" (radius) of the mirror and leaves about 7/8 inch
clearence from the outer edge of the tube.
So, will a baffle like this mess up the airflow and reduce sharpness? I
will certianly try mounting it, but should I use screws (easily removable)
or glue (removable, but not easily?) Are there any modifications I should
make to improve the airflow?
