« Part 2: Gantry with height adjustment mechanism Part 3 of Homemade Band sawmill series Part 4: Gantry Rails and log bed »

Got the blade guides and guards completed this weekend. It took longer than I thought to make the bearing guides but they turne out good. I put them in slots that prevent the nut from turning so I can tighten them from one side only.

The guards are very minimal. The reason being is if a blade breaks then it is just to stop it from flying out to the side and possibly hitting someone near by.

Got the switch on. It is removeable for packaging and transport. I managed to cut a small black locust log up also. It cut fantastic with no vibration. I got seven 8” wide boards that were 1 1/4” thick.

I also managed to make a crude Kant hook to move the logs around. It works well and is adjustable for larger or smaller logs.

Next thing to make will be the rail system and clamping for the saw and the logs.

You have made great progress Sean. How fast were you able to feed the saw blade through the Black Locust log? Did you turn your wheel edges flat or did you put a slight dome on them?

Awesome machine!
Like this simple design. Just a thought: in many office tables, of the kind that raise and lower, there are a toothed belt in the top that connects the motor and the pulleys. Would it be wort taking one of these apart in order to have only one handle to turn?

Looking forward to next part!

Lee- the log was 54” long and each pass through took less than a minute. The wheels are dome shaped to keep the blade centered on them. Here is a pic of how I did it but this pic is from my 16” bandsaw build. This setup is on my router with bearings and shaft installed. Just tilt router 5 deg.

kaerlighedsbamsen – I thought about using only one handle with a chain. When the sawmill is raised all the way up the motor sits between them and would interfere with the chain and I would need to raise them up too high to be comfortable to reach and turn. It doesn’t take long to turn with 8 turns per inch.

thanks for the comments.

Some nice engineering going on there.
