oh yea, diesel also weighs quite a bit more. So now you need to build beefier and heavier to support the weight.

For the cam lock log dogs (or any other kind) I was wondering if they were sloped towards the log a bit they would push down when tightened there by avoiding the lifting of the log? Kind of like having some preset in them.

I had screw type log dog and found them slow to set and always thought the cam lock would be so much faster.

I love having the springs. the sleeve on the 2" square locks like the cam locks bar but the spring holds it from moving.

Lot of great ideas on that Logosaw band mill.  Here is my cam clamp I made.  The handle/lever was just some scrap " rod that was already bent.  The cam is a piece of SS rod.  The bolts are Grade 8 5/16" IIRC.  The tube is " wall 2x2.  The clamp is 1x1 solid steel.  The point is level when you start and angles down slightly when fully clamped so I suppose it pulls down a little.  They work fantastic - easy, FAST and very strong.  The only problem is the lower bolt prevents me from going lower than 7".  I might try to countersink it or replace it with a roll pin.  I made a smaller one that is rotated 90 for doing the little stuff.


 

 

 

 
They are not quite so pretty anymore but still function great.

Nifty log dogs. I will make powered, but this still gives me close up details. Just need to replace a hand with power. :)

Diesel is definitely more weight, but If I am building the mill, and it will cost little different because of my free parts, I want a high production machine. If it was choice between free 22hp or spendy 50hp, I would go with the former. If it was a manual mill it would also play in. So in the end, I will look at my pile of stuff and make compromises where it makes economic sense and time to build sense. 

On a side note, someone just gave me a functioning Foley Belsaw with 36-40" steel blade. Not sure if this is something that can be automated?? I had not considered a circular, but it was free??

Realized that a cam is not neccesary when hydraulic is pushing. :)

Those are some very innovative dogs.


Here i can buy red diesel cheaper than gas and it lasts forever.  Im on a break from it now, but i make waste vegetable oil fuel and conversion systems.  

Gas engines mean eventually fooling with carbs and ignitions.. Not a week goes by that i dont have some stupid gas engine problem.  Coils, breakers, condensors, distributor buttons, wires, never ends.  My diesels are always easier to keep up.  

I would consider a small mechanical diesel for my saw and a $99 throwaway Predator for the setworks.  Buy 2 and a warranty.  Any grief and you swap them out then get another like flashlight batteries.  5hp sounds small.. But 5 horses can pull huge loads.  You use a small displacement pump (low gpm) and just wait 3 seconds longer, big deal.  Its when you want 10gpm at 3000 psi that you need bigger motor.  3gpm at 2200 psi will do what you need.  A log dog or backstop mover doesnt need much flow or pressure.. A half hp worth.  


I wish i had friends who toss belsaws!

Actually, very good friend that I gifted the mill, a lathe, and metal milling machine to. All old beat up stuff. Anyways, he recently got a steel rail Foley that is quite a bit nicer w/42" Carbide blade. When he knew I was looking at building a bandmill, he told me he did not want the one I gave him and said for me to take it and use it or sell it to fund my project. 

What say you Gents? Folley Belsaw with "steel" blade. New cardbide insert blade would be$$$ for starters, but are steel blades poor performers?

Next, is there a way to make these automated. Feed already is, but it would need log turner, loader, dogs, etc..

The log bed is too thin for any trama, so it would need a bed to feed it. But even then, the space is not there for the additional automation (as best I can tell).

However, if I disassembled the sawmill and put the power-plant (tractor) and blade/bearing blocks alone to one side and then built a beefy feed and log management on the other, it could have some potential perhaps. I lose all portability though.

May need to stick with the bandmill idea, but this is tempting.

I have toyed with the idea of going circle several times, but can't make it work for one man efficiently.  Take the mill maybe you can do something with it or use it as is.
