Also was that a solvent you used for bonding the end cap on your tanks, or a two-part adhesive? I thought of bonding them on with something like Sikaflex.

Its a hard PVC solvent Cement and used to glue plastic pipes together. I am sure you will get something similar to this in UK. Sikaflex might work as well, but i would check this before. What do you mean with pulley spindle? Got a Picture? Gruss Stefan

Don't have any pictures, sorry. Never seen one, just read about it in Norberts book, 'Model Submarine technology'. I'll attempt to describe it.

It's really a cheap form of ball screw, instead of using a threaded nut bolted to a gearwheel, you machine three small, threaded wheels which are ballraced and fitted to a spigot at 120 degree intervals, which attaches to the gearwheel. The three wheels engage the thread to get linear action, but because the area of contact is much lower than a threaded nut, you get much less friction.

I believe Norbert used this in his 'Forelle' model some years back, but no pictures were published of the device.
