I have seen some discussion given to considering a band saw design here instead of a circular saw design.

Band saw mills have clear advantages over circular saw mills. First, a thinner kerf. The kerf is the width of material that is removed and converted to sawdust by each cut. Band saw mills have much thinner kerfs. Secondly, in the same stroke, a band saw mill produces much less sawdust. We’re talking the difference between a small pile of sawdust and a large mound for a single rip cut. I have not found sawdust in volume to be a useful feedstock for any other process besides preventing plant growth due to its high surface area and nitrogen-hunger.

I currently own a 36” chainsaw mill which is closer to a circular sawmill in terms of sawdust production and kerf size, and I would switch to a band saw without batting an eyelash if I could afford it.

I do not know of any relative disadvantages of band saw mills over circular saw mills but I would like to hear about any that you may know of.

Do you have any published plans for the assembly plates? Or the pivot plates ?

I would like to try making this unit and would CNC plasma cut those units.

You appear to be using 555PSI to create them but were you able to test their strength as individual masonry units? Naturally this will vary depending on the composition of the earth used but do you have any typical numbers? I’m curious about passing inspection.

I’m very impressed with this project.

Can you tell me why there seems to have been little activity on the LifeTrac project in the last 4-5 years? Have you just moved your attention to the other projects?

Also I think it would be great if there was more footage of the LifeTrac 6, especially doing actual work. From what I can find there’s flashes of it here and there but mostly of the older models.

Also have you thought about opening a Liberapay account?

Regards,

Mark

Was there a consideration of using a chain-mounted bit system more like commercial units use? Why, other than simplicity, was a disc chosen as the trench blade?

On the other hand, do you have anything that can cut down watermelon harvesting time by 50%?

Thanks!

I'm a student of the University of Trento (Italy) and I have to make a pneumatic project for a course. I would like to propose yours because I think that is a fantastic idea. The problem is that I have to redraw the pneumatic circuit in another way rather than you. Can I ask you please which software do you use?

Thank you.

I very interested of your activity, please send informations of all.

These structures will last 1000 years or more without wood. Using Earthen plasters inside and out will allow the structure to provide evaporative cooling inside on hot days as well as provide warmth and slight humidity on dry cold days.

You guys give me hope for this world!!!

Keep goin!!!!!!!
