Reciprocating Saw Repair

While cutting out sheet metal to repair a portion of the rusted floor on our old Dodge Caravan, I ran my cordless reciprocating saw at a bit too high of a duty cycle. The plastic in the drive motor melted. Luckly, everything else in the saw (gear box and switch?) were well built, high quality parts. The motor was standard, and a trip to Princess Auto found an easy replacement.

From 2008 to 2010, I worked in a lab where my primary project was the upgrade of a helium dilution refrigerator so that RF measurements could be taken on a experimental package. This system, previously used for helium experimentation, was massive. Huge pumping speed with 6 or 8″ lines, double sealed mechanical pump, roots blower. This is no small dilution fridge!
