Hey Buddy, I didn't fall far from that tree myself

, both My hearing and sight are giving me trouble these days, so I can certainly understand where your coming from. I've never done sheet metal work for a living, but have dabbled in it on projects, and i can appreciate what it takes to do good work, there have been a couple of occasions when I had no problems having a ac place with the proper brakes and equipment make up something up that I had in mind for me, or even make up a couple of patch panels here and there that were a bit more complicated then I could make with what I had to work with. Hope I didn't sound like i was preaching, cause that's not what i was doing, I was just trying to share that method in case You didn't know of It, but I imagine it is one You have used several times in that line of work also. truth Is If it were My own stuff, I usually get more In a hurry, and cut a few corners, so I'd probably be doing the same thing as You are right now

, someone Else's stuff is another story though. When It comes to my own stuff though function is usually My main concern.
Yeah I always hate when I get a new saw, and the blade doesn't center the same as My previous one, If they are off It's no big deal as long as I know what saw I am using when I take measurements. I usually take that in to account when marking off my pieces, and mark what side of the line I need to cut off of, or if I need to cut the center out cause i knew My measurement was just a hair long. Still it's not brain surgery I know, I guess it's just still etched in My brain from when I was a teenager, and worked with a friend of mine that was a crew chief back then, he was only a few years older at the time, but moved up quick, and started his own business at a young age due to the fact he did such good work. he required us to do framing work as if it was finish carpentry Instead of ruff work as some people would do It. That just kind of stuck with me over the years anytime i was doing carpentry work, as well as other types of work, and Actually has came in handy with metal work as well. With that said everything around My own place is half ass, and falling apart,so there is a distinction between what I do for Myself and they way I do other's work, and so I get that side of It. Just trying to give My input in case it was of any help to ya. With siding I would normally rip those the same as You, even with a skill or table saw, then when I get to the last piece that's up against the trim in your case or an uneven wall, I scribe It and switch to a jigsaw. sometimes i would start with that piece, just depends on the type of situation. Now that's what i would do in a perfect situation, but sometimes it's not worth the extra time and effort I suppose.
Sounds like a lot Of products mentioned here that i haven't used yet, so I may be trying some of them soon Myself:thumbup:
Good Luck with Bubba, hope it turns out nice, if you were in My neck of the woods I would offer to swing by and give ya a hand:smile:
