How much is it worth? I might be interested. I wonder if welding broken blades is worth it, or if they are about to break somewhere else. Although they tend to break at the welds, so maybe the rest of the blade is fine.
If you aren't losing much more than a little bit needed to get the ends dressed back square and clean, You're probably good.
If you hit something that takes out ten inches worth of teeth...?
Sucks if that happens with a blade on the 2nd cut or so.
Blade will probably be too short for the saw if you just re-weld it.
If you have the welder, you can keep the blade until you get another short one.
Assuming that blade are same kind, Pitch and offset, etc.
And preferably both/all pieces in pretty close to same condition wear and tooth wise.
Now you probably have enough blade material to cut and weld into one band that fits the saw.
Once again, I'll mention nice strait weld joints. A crooked tooth or joint could leave a deeper mark in the board face. Are you gonna lose a bunch of extra stock by having to plane those marks out?
Like almost every danged thing else in the tool box, does it make since for you to own it.
Do you need to fix blade problems "
that day" kind of quick?
Does new blade shipping turn into weeks or more and you have a tighter schedule than that?
Are you in a situation that breaks a lot of bands?
Wood that's been dragged around and who knows what's stuck in it?
Is the wood coming from somewhere that people seemed prone to putting things in the tree crotches? Bottles, rocks, critter traps, chains, plow parts, etc.
Sometimes you might not have much choice for culling the wood.
Granted I'm clutching for the extremes mostly, but that's kinda where you need to look and decide if your needs fit in.
The folks who've been off shore or worked in remote areas (like Alaska)?
And yes, You Military Veterans too!
I figure they can tell us about a whole bunch of stuff that steers your needs and choices, That I ain't thought of.
And your band mill might be fossil fuel powered in your location, but will you have a way to power the welder in that location?
I'd bet there are hidden jems in these sort of threads.
Edit: sorry guys, Somehow missed that my attempt to merely link, turned into a copy and paste. I get some truly Weird crap outta this laptop sometimes.
