=========================================

After a year of working on this off and on and a few hundred hours I consider the sawmill finished enough to put away until it is time to put it on the layout. This page will be more or less an overview of the near finished build.

The sawmill complex is a little over two feet long and about a foot wide at the green chain end. Also needed is room for the mill pond, air drying yard and a loading facility at the tracks which all take up space. It will occupy the upper level on one end of the layout and will be a scene in its own.

Logs will arrive by rail and truck on the far side of the mill pond (not shown) and be off-loaded there into the pond. A boom boat will then organize the logs and move them onto the log-lift. There will be a second boom boat for the times the other one is out of service for one reason or another.

The logs then move along the chain and ….

….. into and through the debarker building where the bark is removed. From there they ….

….. continue on with the chain and into the mill. Once in the mill the paws on the chain push them onto the transfer table. There they stack up and then roll onto the carriage. The carriage takes them back and forth and slabs are cut off on each pass through the bandsaw.

As the carriage passes the band saw a slab is cut off and falls onto the rollers next to the carriage. If the slab is actually a large timber that won’t be further cut when the carriage pushes it onto the roller it moves to the left down the rollers. A large cutoff saw there cuts it to length.

If a slab moves over onto the rollers there are chains there that move it further over to the second set of rollers. The slab then moves through the edger saw and is turned into a board of some width with now straight edges.

The board moves along the rollers past the edger and then is moved over to the table going into the trim saw by a set of chains. The trim saw cuts the board to length with waste coming off both ends. The board then moves along another chain and out onto the ‘green chain’ for sorting.

Above we see the main machinery (some not painted yet). Show is a re-cut saw and a planer. Any lumber that ends up on the green chain that has flaws is brought back into the mill and run through the re-cut saw to remove any damaged ends. Lumber that comes off the green chain and that is to be planed goes to the yard and is air dried. When dry it is brought back into the mill and run through the planner. Lumber from the planer and re-cut saw is shot back onto the chain to the green chain by fast moving conveyor belts.

The numbers above are the numbers of the print files that are all up on my thingiverse account ( HERE ).

It is easier though to find them if you go to the menu ( HERE ) for the whole build. There you will find much more info on each section of the mill along with links for the print files for that part of the mill.

More info on the green chain ( HERE ) and ( HERE). There are some roof options to consider. One can print it as a stand alone green chain with its own roof or you can print the roof to be connected to the main roof of the mill as seen further down the page.

The roof lifts off to view the interior of the mill. Also the …...

…. trusses and post and beams under the green chain roof can lift off also.

This brings this build to an end until I have scenery and track finished where the mill will be placed ( HERE ).
