Living in a metric country (ie almost anywhere but the USA) brings major challenges with Meade gear as there are dozens of thread pitches in use in the USA and many are really hard to find in the metric parts of the planet.
The reason I need the thread information is that Meade in their infinite wisdom probably allowed the work experience kid from the local high school to design the counterweight bar and left no clearance underneath it to fit a dew heater strap. I don't particularly like flattening and damaging the insulation on my heater elements. So I have a friend machining up a couple of spacers to raise the bar to a 5mm clearance from the OTA. This means longer screws will be needed.
Does anyone know what the exact threat pitch and thread type is for the counterweight end stop cap screws and also the counterweight tube mounting cap screws?
My local engineering fastening shop was defeated by them and couldn't match the threads. This is unusual in that they carry a good range of Imperial and US fasteners.
Can any one please help?
