exactly what I was thinking..........lol

I mulled thing over this morning and came to the conclusion that you can build one of these even if ya can't weld. You could make all those joints with sturdy angle bolted to the box sections with rivet nuts etc. It would take a little longer and involve a lot of drilling etc. But it would sure work. As I said before, I am lazy so I welded things together that do not have to come apart or need to be adjusted in time. But what I am saying is that anyone can build one of these and other things if ya just sit down a minute and think about it. I have about 800 bucks in this thing for materials that I had to buy ..... the rest id re purposed stuff. From a floating dock, a boat trailer, a old 6x6 ATV a boat prop shaft ... the " dash " with the switches and relays is a 30 cal ammo box.
I don't know if " Mechano sets" were ever a thing on this side of the pond. But think of it as metal LEGO. where you get to build stuff out of little strips and able of metal with small nuts and bolts. I has a bunch of that stuff as a kid. Now as a semi adult, I few the whole world as a large size mechanic set. So if ya put yer mind to it, there is almost nothing that ya can't fix or if it cant me fixed .. make it new. All of my tools are in a 8x19 foot enclosed trailer including the work benches. Even my hand loading stuff has room in there. So ya don't need a big shop either as an excuse not to make what you want.
Using this saw mill as an example. As a whole it may look daunting for someone to build it. But its just like eating an elephant ..... you do a little bit at a time. Divide the job up into smaller and smaller components and concentrate on each component ... then it all comes together a bit at a time. I did not make a single drawing for this thing and just " made it up " as i went along. Its part of the big elephant of building a house by myself with the materials that grow on my property. For that house I need lumber. So I need to build a machine to make that lumber.

I didn’t see the three screws for adjustment on the shaft, I have never seen it done with one bearing and was wondering if there was a specific reason for going that rout, and I do know that adjustment on three rollers is a pain.
