[papercreters] Re: mixers

The best bucket holder I've ever seen or used is also the cheapest one
I've ever seen. I learned it from an old timer during a Habitat
project.

This old guy set a bucked down on the unfinished subfloor. Then he dug
up 5 scrap pieces of 2x4. He screwed two of them down around the
bucket at a the East and West compass points. He placed them just
close enough together that you had to kick the side of the bucket to
wedge the bucket between them. A third block got screwed down at the
North compass point.

The South compass point he screwed down about a foot away from the
bucket. Then he took his long (1ft) scrap of 2x4 and used it to wedge
between that far South block and the bucket. You stand on that longer
piece to keep it from vibrating loose while mixing.

Dang if that didn't work really really well. I still use the same
technique today if I'm going to be mixing several buckets.

If it's just one bucket, I still use my feet. WEAR BOOTS!

Watch the old timers, they know every time and labor saving trick that
exists!

[papercreters] PTO safety

I was looking for PTO driven mixers when I found this feed mixer
article. Exposed shafts are dangerous if left uncovered. Be real
careful if you design a stationary mixer with a similar powertrain.

Dang, I missed it. You're only a two and a half day bicyle ride from
Tucson. I'll have to catch the next one.

Re: [papercreters] Re: mixers

The videos that blender company makes are hilarious!

Of course, for $400, you could buy a lotta drills...

I wonder if you could attach some curved pieces to the ends of your mixer blade that would ride on the sides of the bucket to keep it from cutting through? Or would that render the blade ineffective at pulping the paper?

[papercreters] Re: Mortar (papercrete mixes)

Janosh, I can speak only from my own experience. Portland so far is the only thing that really works for me to make a hard, tough, and durable block. When we started using metakaolin we were elated that set time was reduced to hours opposed to days, and shrinkage reduced considerably. What we didn't know at the time was that the metakaolin, at least in the proportion we used, reduced strength and hardness. At least most of the time, which brings me to the next point: The thing that I'm currently really curious about is that the quality of the blocks we made using the same mix design on the same day (same weather, etc.) varies so greatly. I've been wondering if it isn't water content at the time of pouring that makes the difference...I put it this way (time of pouring) because typically the mix poured first off the top of the barrel is wetter than that poured last from the bottom (despite all our efforts to make it homogenous). ...But then again maybe it is the reverse--the wetter blocks cured harder. We just don't know, and are busy building with the blocks we have, not making more just to experiment. I've wondered if adding lime to the mix wouldn't aid the pozzolanic reaction of the metakaolin, based on our positive experience with the mortar mix.

I definately (as in really, really, really!) want to hear from you what the results of your experiments are. You might stumble across the answer to some of my questions about our blocks. Also, I'm curious about the effect of climate on papercrete set and cure characteristics. We observed the blocks poured on cold days (with colder nights!) took longer.

I know this post doesn't address many of your questions but I hope it adds some useful data.

Eli
