Hi Stephan,
are you only using the 12" subdia lap on the 33", or do you use a bigger one also?
My in-house polishing area (front half of living room) has been "annexed" (we replaced carpet on concrete floor with floorboards, so I polishing is banished from there), so I am setting up in the basement. I am considering making a subdia lap as I found progress slow and difficult with the full diameter 22" lap. Hopefully I will get restarted in the next few days (coming back to parabola from sphere(ish!). But mainly I have been busy with the renovation, work and family life (and made a safe, unobstructed solar dobsonian in time for the mercury transit. No sunspots now so it's a bit useless for the moment. :-(
Cheers,
hamish
