First pilot hole,, never made thru, never even got to try the 3/8" Drill bit
Well Richard you must be a more robust fellow than I am, I'm only 72, never been over weight, never had heart problems, never been a tobacco smoker, worked with tools most of my life, electronics tech, machinery tech, construction electrician and so forth etc..except for allergies and bouts of Flu, no serious illness, always had good health, there's cancer in the family tree, my mother and a brother, but I've been lucky , maybe it's simply the drill bits, but unless you weigh less than my 120#, I think that is part of it, so was the difference in our working positions, I was squatting , you said on your knees, in that position your legs thigh muscles give you some leverage to brace against the force of yours arms pushing on the drill , I'll park the RV different next time, and try doing this on my knees, I know that squatting is not a good position for me , doing this job, not efficient use of my light weight body mass
I spent a great deal more time than 5 mins, way too much time, I'll buy some more bits before I try again
