Tip: To ease the tool into the hole and break up some of the crud in the threads, I use acid, usually phosphoric. The cheapest source of phosphoric I've found is Water Softener Cleaner, green liquid in a bottle. Spray or brush it on the threads prior to mechanical thread chasing.
RV,
You are getting a pretty extensive video library compiled. You may get to a point to be like Mark Polk. He gets all kinds of sponsorship and free RV components because of his viewership.
Best of luck and keep the vids coming. Good stuff.
