Hello Cherryville Chuck,
Thank you for the detailed e-mail. Hey, never underestimate motivation when it comes to learning! I did go to YouTube re bay windows and did find enough to realize that there was a fair amount I needed to learn; the window book I took out of the local library was a further help in revealing my ignorance, but that was very helpful in beginning my search. Thirty years ago a friend and I built three windows for our kitchen, two of which opened (casement types). He was a retired carpenter (highly skilled) and coaxed the wood through my horrible saw. I'm looking at these windows and trying to recall what we did (Tom died at the ripe old age of 98 last year). And I'm checking out the other wood windows in our house; I bought these windows a few at a time as we could afford them and installed them myself. I'm now on a wait list for a woodworking class and I shall immediately view this YouTube link. Thank you very much.
Oh, and by the way, my old saw is now outside under cover. I threw a masonry blade on the thing and it's been perfect for cutting paving bricks which I've recently installed for an entrance to my basement. Did the same thing with an old skill saw to saw through 2' concrete pavers. Simply wear a mask and vroom. I find this way much safer than using an angle grinder. But forget about pavers...back to windows and routers! Ciao, Gary
