Thanks to whoever it was that fixed the images.

They are stretching the page on my laptop and making it very difficult to read the posts. I'm having to scroll across the screen on every line. Thanks.

Amedean Messan wrote:Thanks, keep in mind though that you will need some leverage to generate enough pressure. I weight 290 lb so this is not a problem but a 12 year old will possibly not generate enough force - though I am unsure. Also consider spending a little extra to modify the mold so that the block can be extracted more easily. The extraction is the most difficult part because of the built up compression and can result in a percentage of defects which is why I would recommend a two layered system which enables the inside mold to be extracted intact.

I was thinking I would have to add a third stage to the press.... and a platform for him to stand on
It would take some experimenting for us to get it right.
Connie Farmer wrote:I've often wondered if you could rig one of those old bumper jacks to compress the bricks. Some people call them jack-alls. Seems you get a lot of leverage with those, and they are well made, especially the old ones. Easy to find, not too many people use them any more.
Amedean Messan wrote:Also the design of the compound lever press I made initially can be made much better with some thought but the principle is the same. The mold will need to be fortified because a lot of compression will break. I like the idea of carving one right out of a segment of a tree trunk.
I am going down to the lab. Do NOT let anyone in. Not even this tiny ad:
