Undersized wire to the shop could result in the compressor seeing less voltage than it needs. What is the distance between circuit breaker and outlet, and what gauge wire between them? If the answer is 100' and #14 that could be the problem.
Thanks for the help. I won't get it wet and I'll avoid scoring the back unless all else fails. I suspect the Aussie stuff has some kind of flexible surface bonded to it.
My new plan is to do it over several days. Force a section into place with some kind of form. Glue and screw those few feet...
I want to put MDF baseboard on the "inside" of a curved wall. Radius is about 8 or 9 foot. Can I do it without the stuff breaking? Any tips / tricks? Score the back? Wet it like drywall? I do not want to use the pricey rubber molding.
