I found some useful images googling " sawmill jacklift". Most mills in our era used an endless chain that had claws on it to grab the log and pull it up an inclined plane ramp.

Thanks Bob, I'll try google that. I have found some sawmill pictures with the ramp. Is it plausible to think that a log haul is made up of the following?
-ramp
-chain with claws
-a pulley wheel below the water surface
-one pulley wheel at the other end of the ramp connected to a power source
-some guide wheels on the ramp for the chain to follow

Do you any ideas on colors for the sawmill equipment?

Thanks,
Håkan

When i get home I'll post some pictures of how I model one. But you got the basic idea. Á far as colors, look to the frames of your stream engine. The same colors were Common to all machines.

Here's my model, please remember it's over 30 years I've learned a few thing (I like to think) since then;



The plan was for the 1x2 that is supporting the Jack-slip to go into a slot in the log pond and be about 1/4 inch below the pond's surface. The seam would be hidden by floating worker's platforms and a log just starting up the lift.
It is planed for this MIll to get the TLC and upgrading it needs but it is a low priority. I have some photocopies somewhere of a photo of an actual chain drive mechanism. Would you like me to hunt them up?

Thanks Bob for you help. Those photos were great! That is some beautiful craftsmanship on that sawmill. I wonder one thing. Was the chain hanging free below the ramp or was it for the return also supported by pulley wheels?

Yes thank you if it is easy for you to find the photos on the drive mechanism. My sawmill won't be that easy to see all details on so I probably can simplify things. But I'm curious to how it looks and functions.

Thanks,
Håkan

Håkan, there was a pulley under the water on the other end and another pulley that directed the chain from the drive mechanism to the tunnel that lead from the mill's basement to the log pond.
I'll see what photos I can find tonight. Unfortunately this research was done in the pre-digitail, pre-computer and internet days.

Hi, thought I show some progress pictures on the sawmill. I have not done so much progress but the machinery is taking shape at least. The castings in the Keystone kit is great and need not much cleanup at all. I have contemplating which colors to use and I went for a dark green close to Pullman green on all the equipment the idea being that the management bought everything from the same supplier to have the mill up and running quite quickly. As the sawmill will be quite new and only year or two in operation I'll weather the machinery moderately with not so much rust but more filth and oil deposits.

As the place it will be mounted on the layout is quite hard to reach I'm building it on a base so I can make everything at the workbench and then mount it on the layout. Yay my first diorama

Sorry about the quality. I tock the photo with my Iphone which has limited depth of field.

Sorry,I get when I see that you've posted. I like your color choice. The mill machinery is looking sharp. I build all my major structure on a foundation so it can be easly moved.

Håkan,

Those machines look nice. I lke your choice of green; looks appropriately Victorian.

Mike

I hope you can unglue the log carriage. As you didn't leave room for a log on the carriage.

Thanks Bob and Mike!

Bob, I have seen that. The Keystone castings is one piece. I can't move it back to give room for the log. I guess they are on the last plank. I need to add the hook.

I would have liked it more like this:

That's a bummer! Can you rebuild the carriage? Cutting off the blocks and build a new frame?
