Jacq's Logging Project Discussion

[John McGuyer]

History channel just did a thing tonight on the history of logging. They went from showing shays dragging out disconnects to some thing that now cuts down 18" trees in just over 1 second. There was even some six legged walking thing for tough going (Marc would love it).

Shoot? sorry I missed it. Sounds like Ephraim Shay meets George Lucas

  The book LOGGING by R.G.Clement came in today.  Thanks Marc for recommending this book and a very nice coincidence that the original 1913 issue is republished by OSO publishing via the NMRA.
  It contains the best background information, making it possible to understand what I am doing.
  Is there a similar type book available about mill practices ?

Jacq,
Darryl Huffman sells a "book" on CD published by the forest service ( I think) that explains sawmill set up, building and operation very clearly. Well worth the small investment if you wish to do things correctly.

  Marty,
  thanks for the hint, I have the CD Small Sawmill Operators manual.
  It contains all the info to design and built small circular saw mills with the emphasis after wwII, no or very little steam.   
  No coverage of large bandsaw mills like Pino Grande / Hume Bennett/ Mumby Lumber etc.  serviced by railroads.

Jacq,

Bryant also wrote a book called "Lumber, Its Manufacture and Distribution", that might help. The entire book is availabe for free download from Google Books.

I was able to download the entire book  590-something pages as a PDF, no problem.

It should be right on the right of the screen above where it says about this book review.  Contents!
It should say download PDF-16.4

Marc thanks for the link might just have to make a copy of that pretty interesting.

Nope,  niente, niets.

  I only can get the dutch Goolge variant       , whatever I try.

  Is it possible someone send me the downloaded PDF file(s)

On its way to you Jacq?

  Marc, Paul, 

  thanks for the link and sending the Pdf files.
  A lot of reading to do / going on. These books have the backgroud info I was looking for.

   Finished reading the logging book and started on the Lumber book.
   Reading with a book in the hand is far more comfortable than trying to read 590 + pages on screen.
   I managed to get the first half copied double sided and bound and read through the part covering the sawmill machinery and set up.  A wealth of information regarding "working in the US " and sawmill practice before 1922.
  I started with the plans for the mill in 1:48  or 1/4" scale.
  The footprint is ready, I have to redraw it in a lot smaller scale to be able to publish it as the scanner cannot handle items larger than A3 sheets. Maybe at work.
  Ready :  the ground floor with steam engines, sawdust conveyors including concrete covered area.
              the saw floor with head rig, carriage way, log deck, jackslip, live rolls, transfer tables, edger, dead rolls
              and resaw. The filers room cannot be finished until I have details of filing equipment.

  Here a cross section showing relation Bandsaw, carriage, top of jackslip with chaindrive, position and slope of logdeck. Other sections across steam niggers, live rolls, crosstables and edger and entree of green chain are nearly finished.  Several details are drawn for patterns so I can cast my own PU parts from silicon moulds.

The most time will be taken by preparing NEAT drawings instead of my concept sketches drawn exact to scale,
like the one below

Nicely done Jacq ? am really enjoying watching this concept come to life.

  Where there specialised  design / architect / engineering firms around 1900 specializing in mill design ?  Or were mills designed by the firms who delivered the machinery like Allis-Chalmers ( carriages, bandsaws, edgers, re-saws etc. ).  Surely a mill needed to be designed / engineered and materials specified to enable a  good longtime functional structure.

How much tolerances were accepted like moving timber due to humidity to maintain the sawn dimensions, not to mention the abuse and large forces by loading/ turning logs on carriages. 
I can imagine the very high fire risk caused by high friction in to lineshaft bearings due to misallignments caused by setting of building parts.  Rotting ( struvtural) timbers under the logdeck must also have been a problem.
Reading about the large amount of burned down mills this must have been a large problem.
Comparing photo's of several mills, I can understand why Pino Grande didn't have a fire. All photo's show a clean mill, so I assume this was a company policy.

The Bryant books are a revelation in understanding milling and logging philosophies and - politics, compared to all the advises/stories given and told on fora about the topics.
