Look forward to your next update Nejc.
I had to change the log deck machinery, because logs weren't pushed far enough with the old configuration:
...so I added another speed reduction gear set:
I also added a different log kicker:
...and now something that was one of the most challenging things in my modelling ''career'' till now - designing, building and mounting the upper husk. Before mounting:
You can see the tensioning pulley here:
...which can be operated via this lever (it's purpose is to ''shut down'' the upper husk saw, when logs are smaller):
Upper husk mounted (note the mirror configuration of the new mill's side wall - reason is improved visibility of the interior equipment):
Three identical holes on the second floor are for the lighting and long linear hole is for lifting the saws up for sharpening:
That's it for now

Fantastic job! The machinery and the sawmill are wonderfully done. I am really looking forward to seeing it in the layout. The catenary system on your first picture is really cool and really love this type of rail system. Keep up the fantastic work.
Jim
Thanks Jim!
A bit of progress - machinery in the new mill is done and machinery in the old mill is almost done.
Here are the pictures of the cut off saw and the overhead log turner in the new sawmill:

Old mill pictures coming soon

The belt system and the rest of the interior looks terrific! I did want to point out the overhead log turner...it's extremely red and stands out from all the other details.
Yes Bill, my name is Nejc

...I don't know why I had in mind that they are so reddish
Pictures of the old mill:
Note the overhead log turner and lifting system for the press rolls of the edger (modeled after Phillips Brothers Sawmill edger):
Another cut off saw:
...next on production line are steam engines and boilers
The color of the friction cones looks spot on after the touch up.
Can I offer one more suggestion (or am I pushing my luck)??
Looking at the areas where the moving parts make contact, they'd be pretty shiny because of the friction. Simple fix: If you take a plain old pencil and go over those surfaces, you'll get a cool polished effect that looks like wear from metal on metal rubbing. Just take the pencil and rub the lead on the angled edges only:
I use this technique on any pieces that show metal wear: teeth on gears, pulleys, anvil surfaces, tools, etc.
Bill, any suggestions are always welcome!
Were these things made out of metal? I had no idea how cones show wear but then I found a coloured picture of the overhead log turner from the McLean sawmill in WSM book. It seems to me like white/grey patina over the big wheel friction surface. So I used a mixure of pencil and chalks to achive this:
What do you think?
Regards, Nejc
Some times color photos can show machinery that is really old, broken down, or completely out of service. Raw metal will oxidize in no time if it isn't seeing regular use.
I'm no expert, but I think most of those transfer wheels were all metal. I have heard of some called "paper friction drive" wheels which look like this:
So, in this case, both wheels are metal but one was wrapped with a paper material. In my sawmill there is a set of transfer wheels that are called "angled bevel friction wheels". Most of it is hidden, but I modeled them shiny like this:
At this point it's probably splitting hairs. You're doing such a nice job on this model I figured I share my thoughts with you. With the more muted coloring, I'd say it's perfectly acceptable.
Bill, McLean sawmill is still operating (or at least it was when those pictures were taken), so it shows wear quite realistically.
Anyways, I looked at the Ralph C. Bryant book Lumber if overhead log turners are described into detail and voila - bigger wheel was made out of steel, two smaller ones were paper-faced friction wheels. I guess it's always similar with friction drives, one wheel being paper-faced for better friction.
So here's the latest version of the overhead log turners, with two smaller cones ''paper wrapped'':

You're right Ed, plus a detailed description of this type of log turner (with picture) is in the book I mentioned before, called Lumber...
Here's the progress on boiler and engine room:

Phil,
you're right, many details still to come! Small tools, boxes, benches, tiny details overall, some stains...I'll also put some slabs and sawdust to the boiler house - plus I'm planning to get flickering flames into left boiler, holes are already prepared. But I'll keep sawdust out of the machine house, I think that they were cleaning it pretty thoroughly from there.
Ed,
Laibach isn't my type of band actually
Specially Siddharta have some songs in English and were pretty big hits at the time of release all over Europe. I'm sure that they would be world class if they weren't from small country like Slovenia
While I'm waiting for some bevel gears to finish the overhead belt drive system, I finished the lighting but it's not yet installed, because belt drive needs to be finished first. I also made progress on the old mill roof, pictures soon...
Nejc
Thank you Karl, nice to hear from you
