[PSUBS-MAILIST] Welding

[Alan James via Personal_Submersibles]

Hugh,went & talked with a welding specialist this morning who seemed to thinkthe plug idea would be good. His only reservations were whether I couldget the plug out afterward. I said it would be designed to be able to bepressed out.The bearing seat is some distance from the welding & has a thick sectionof aluminum between. See attachment (not dimensionally correct).The plug should stop the tube section from distorting, shouldn't it.I have 6 of these to make initially & it will be a lot less work if I can weld.I need to go with the steel plug as an aluminum plug could get damagedin the pressing process.Am I convincing you or does this still get the thumbs down?Cheers Alan

Alan,
Stay away from welding or completely re-machine as Hank says otherwise you
will havev concentricity issues with the bearings etc.
Besides Aluminium will be a better heat sink than a steel insert.  Hugh
