Despite 15 deg. weather I started mocking things up today.

I decided to use 18.75 pulleys. I considered 12" trailer tires but I felt with the tires there would be too many variables for inconsistencies. Also if you are buying supplies the tires are not any cheaper.

I plan to drive the blade off the "pull side" pulley as I've seen on manufactured band mills. I plan to use a cintrifical clutch.

The one thing I am considering is to use a tensioner rather than just an idler. As things wear or heat up I'm thinking the tensioner would keep the blade tight and would also make changing the belt easier.. Thoughts?

I'm using 1" shaft. Pictured is small round-stock for mock up only..

If using standard cold roll round you will need close to 2" shafting.

You MUST pull the blade through the wood, you can't push it.  The blade tension will not be consistent if you try to push it and your cut quality will suffer.

I had two vehicles get their timing belts changed and had them keep the tensioner and idler pulleys for me.  They are really just rollers.  I used one on my sawmill - works great.  Since it is flat, you will need a way to adjust the pivot angle so the belt tracks ok.

1" shaft will bend, not an if, only a matter of how many minutes of run time.  You need to run too much band tension for the 1" shaft to handle.  1-7/16" to 1-1/2" is normally considered the minimum. 

As shown in your pic, you want to power the wheel on the right side of the engine (which pulls the blade through the cut, assuming a counter clockwise engine rotation).  I think that is what you said you were planning to do.

You will need to have thick skin while running a build thread, as you will get a bunch of "tough love suggestions" that sometimes conflict.  At the end of the day... remember you are paying the bills... so you call the shots!

Thanks all.

My blade will be pulled through the cut.

I will strongly consider upgrading the shaft size. My front pillow blocks will be extremely close to the pulley but that may not eliminate issues..

Someone else on the forum made a mill with 1" shafting.
It kept breaking every time he tried using it.

I have one of the smallest shafts for a build. 30mm.
But its high carbon steel bearing shafting.
It cost a lot more that standard shafting.

Good idea mocking things up on the bench.

If the pillow block bearings were placed on each side of the band wheels as close together as possible a 1" shaft may work but it might be a pain to change belts.

+1 on using larger shaft
Strength of the shaft is not the only issue
*  Deflection of a small shaft will cause blade tracking issues
*  Bearing life will be a big issue unless they are large or very expensive

Deflection & strength issues can be reduced by putting the wheels BETWEEN the bearings but that would require a design change.
You may think that you can or may think you can't; either way, you are right.

I built my mill and used a 1" shaft, I had bought the shaft on ebay and it did bend. I replaced it with a 1" shaft of steel bought at a local steel shop and have been using it since last june with no issues. I am running 20" steel band wheels from an old industrial sized vertical band saw. Also has an 18hp motor. Mostly sawing pine or hemlock.

Thanks all for the input. I'll go to 1 1/2".

Re: Building a mill.. The winch
« Reply #19 on: January 15, 2018, 12:14:03 PM »
I like the idea of a hand winch to raise and lower the saw head. Simple and dependable..

I am hoping each click of the winch will be a specific increment.

For those using a hand winch --  When the spool becomes full of cable, larger in diameter, do you find and issue with landing on your mark????

Thanks
