I'm in north Florida -- effective heat/humidity was ~ 105 F and I was 
installing a ceiling...and...dripping

as for some followup comments - the rings compensate for piston 
"expanding". Just do the experiment..don't trust me <grin>. And for heat 
clenching - the idea is to undersize the hole, heat it, then slip it 
over the object.  If interested - do a google search on how the 16" guns 
where processed for the Iowa class battleships (see
