Like most of you, who've been in construction and woodworking for a number of years, I've invented dozens of tools and machines to make various tasks easier quicker, and more accurate.
I thought I'd show some of those here, and hope that you will share some of the things that you've invented, big or small, to help with specific tasks you needed to accomplish in your life. Please join me in a show and tell.
Here goes:
After closing in my second house, during my relatively brief career as a home builder, I moved inside for the winter work of finishing the interior. With plumbing and wiring in place, insulation was on the agenda. Having just finished "energy efficient construction methods" classes at the local Tech School, I was seriously packing fiber glass into every gap around windows etc., placing insulation behind wiring and electrical device boxes, and covering everything with vaper barrier.
As those of you, who do insulate, know, fitting fiberglass bats under windows and into all the non standard widths between studs at corners and door ways etc, requires a lot of cutting. I tried utility knives, butcher knives, breakaway wall paper knives, but nothing worked very well cutting the 6 inch and 9 inch FG I was working with.
I thought of a large rounded blade that wouldn't snag as you draw it along, and would allow you to work with gloves and would keep your hand above and away from the FG. That was 1979. The thing worked really well, so when I used it recently to cut tons of insulation for my son's 40 x 60 ft shop with 16 foot ceilings, I was reminded how good it was, and the helpers working with us were also impressed, and encouraged me to put it on the market. We've since given up on marketing, but here are some photos of the newer versions.
