2022 what did you do today?

[mmattockx]

Really?   I always just pumped concrete until the forms were full, or up to the grade nails. You just stick your head inside the form and say , " Yup....That's enough mud.", and move the hose down. then fine grade and trowel it flat.  Now they have a machine that does all that automatically?     I'm getting long in tooth i guess.    Kirk

There are no forms, the printer just lays it all on a flat slab to start. These are still mostly experimental, but some real homes are being done this way now and it is going to be a bigger and bigger thing in the future as the technology matures and building codes and permitting authorities recognize/approve the construction method.

Wow!  A mud house, no forms.... That might be interesting seeing the seismic engineering for one of those structures. The modern homes and commercial buildings being built today require special inspections on concrete, reinforcement steel, and seismic hardware and hold downs. i saw nothing but mud in that one.... Pretty amazing machine there...   Kirk

All this stuff was 3D printed
You can also try out your design with 3D parts

Unless they have a way to insulate that concrete, it's gonna be chill in winter, and hot all night in summer...

New Toy day.
Next Projekt will be Hybrid-Longbow-ILF-Limbs.

You can Insulate from the inside nincompoop

Nice bj-s

I realize that, but I'm bettin you can stick build and insulate CHEAPer than the printing and then insulating ,then interior finishing.

Prob don't matter to you rich dudes, but I'm a CHEAPskate...

[kennym]

Besides, that ain't very traditional...

These 3D printed houses are way cheaper to build than traditional wood frame homes. The first areas they are being targeted at is building homes in poor countries where people can't afford houses now. Building out of concrete may not be the first choice in North America, but in tropical areas wood frame construction doesn't work because of insects and rot. In Jamaica many houses are built out of cinder blocks and I expect that is common in much of the Caribbean as well as other tropical locations. These 3D printed houses would be very competitive in that environment.

Now, for bow related topic... The other day I ground a set of lams for my first bow of the year. Been swamped with work, finishing a basement and other acreage projects. If all goes well I might actually get it glued up before the end of September.

Lost my string tension yesterday 
Anyhow two of my recurves short 50 in. and 61 in. Seem to have enough preload the limbs are at correct brace height with very little bending and are quiet to me more string tension and more limb travel helping the fps.

Way to poke the bear Stic!

Ole Kenny lost his string tension long time ago:)

Stic, I still can't believe you built a 61" bow and no one has gave you any grief over it. I built a odd length bow and got told I didn't know what length bow I built.

Who pulled yer string??

I don't know about that anymore bro.... The price of lumber quadrupled the last year or so... the market is coming down again finally. But last year a lot of very large construction projects went on hold over lumber prices in the NW here. 1/2" CDX plywood was running $80 a sheet.    Kirk

[Crooked Stic]

Well if ya go by AMO it's 61. But if ya go by strung string length + 4 in. It is 62
I expect both them old fellars got no string tension.1
