Hi Nuke Power,
I'm trying to figure out how you seal your wtc. I see you have end caps which screw on the ends and have seals and grease, but in some shots (eg showing the drive motor in situ ) half of the wtc tube appears to be removed. How does that large open section become watertight? .. or what am I looking at?
I like the costing of this
Except over here in UK I haven't come across anything resembling an end cap that goes with the pvc pipe in the shops, just bends and t junctions
Though I notice you are now abandoning the end cap for the reasons you mentioned, and are now going to make up some end caps to size, presumably you have found a source for 'O'rings that will fit.
I have been thinking along these same lines - I can get the pvc pipe and now that I have a model lathe I will be able to turn my own endcaps (still yet to source a suitable thick material) then all I need to do is to find a good source for 'O' rings, and I'll be laughing.
