Hey man... Things are looking nice there in your shop! Ive been keeping up with your posts... One word of advice on that new drill press you bought... I have the same exact one and i would recommend keeping some kind of rust inhibitor on the shaft that the table slides up and down on... Mine is...
I bet you could knock that insulation knocked out in a day especially with help.. Get you a window unit or two and put them on full blast... Get you a HUGE fan and close the doors.. I bet it would be tolerable long enough to get it done.. Dont give up u can get it done.
Just my 2 cents
