Subject: [PSUBS-MAILIST] prop shaft
seal
I have been looking through your archives of info and have been looking
for someone talking about sealing drive shafts. I have considered use of a
circulation pump shaft on an oil rig. I can get them pretty easy and it is a
bolt in assembly I may have to have a costom shaft machined by I can use
ceramic seals or grease packed seals. I have had a bit of a prob finding dc
motors that are affordable but don't know what I am looking for. the prodject
I have named murky 1 is at a stand still for design as I am going to be on a
budget. I will be using this in fresh water only at depths not to exceed 200'
and would like to know if anyone can tell me how to find out how much
reinforcement I will need any using 1\8 or 1\4 steel. how deep is a
unreinforced sub good for with a 3' diameter. at those thicknesses?
