Vintage work crew photos

I talked to our communications director about her experience with it this morning, she said 300DPI looked quite good even when printed very large. Now, 'very large' in this case was like 2½ x 3 and 3 x 4 ft-sized photos for awards and retirement ceremonies, not wall-paper sized..

That does look interesting, and the price is not unreasonable, but I can't do even close to that sq ft price. I do see some of those fancy "spray a photograph on a wall" machines around; I might just need to wait a few years until that stuff reaches the DIY world.

ranald - yes, redo please.

Was thinking someone here might want the DIY challenge of a 2 axis with a 11x17 printer head...might take awhile but doable. Looks like something you might see on instructables.

Crib trestle on the Columbia and Nehalem Valley Railroad. The Columbia and Nehalem Valley Railroad was a logging railroad for the Peninsular Lumber Company of Portland in the area around Columbia City, Oregon.

What looks like timber and pipe isn't. Longitudinal members are timber also. I've never seen or heard of cribbing in structural sense, just as individual blocking. I wonder at diagonals too; but friction and a mess of parallel members [probably lagged] could work.

Actually when you look at the interlocking way that log cabins are constructed the walls are nothing more than a stacked cribing structure to hold up the roof .
While many midwestern and western log cabins were made exclusively with full round logs with rounded out notches to hold them together. A popular method in the eastern forests was to split and plane much larger diameter trees to a thickness of 4 to 8 inches by what ever the diameter was then cut tapered mortise style tabs and notches some cabins were made with trees as much as 24 inches in diameter the taper of the trees were compensated for by alternating them end for end to maintain a reasonably level stacking course, the top plates would be hand planned to level. and locked in place with wooden tenons. the stacked courses could have as much as 5 or 6 inches gap between them.
If we look closely at the trestle we can see the top course and the sleepers are pinned with diagonal rods

I don’t think the pioneers and other generations that built log cabins to live in and raise families left gaps of five to six inches between the logs knowing that they would have to be filled with mud or something else and mud to seal them from the winter weather. Barns for livestock were built with gaps between the logs but not cabins. I saw a couple of log cabins many years ago that were over a hundred years old at the time. All the gaps between the logs were filled with mud and dirt.

You should visit Virginia and other parts of the Eastern mountains forest areas some time there are still lots of old log cabins dating 150 years and more ago that have 5 and 6 inch gaps between the structure logs those gaps are filled in with the slabbed off sides cob and sticks but are in no way tied to the structure

I’m very close to Virginia, about 30 minutes away. You must be talking about somebody’s old barn.

There are random diagonal pins through out the structure Rows 3, 6 and 12 are not just the top row.
