CHB Models was the passionate life's work of Charles H. Brommer or as he was known to his many modeling friends as simply "Charlie". Charlie specialized in incredible high quality, super detailed O Scale white metal kits including logging and mining implements, sawmill and machine shop machinery, Dolbeer Logging Engines, yarders, hoist engines, tools, and even a pair of beautiful MACK trucks. Charlie was an old school machinest creating the most amazing brass masters our hobby has ever seen. I was very fortunate to purchase the CHB Models line from Charlie before he passed away and have released well over 75% of the line in O Scale - white metal, since that time in 1999. The CHB Models line was previously only available in O Scale but with the advent of the SierraWest 3D Printing era, many of those legendary kits are now being made available in HO Scale for the first time! Check back often for new details and kits as they are added reguraly.

Since 1995, SierraWest Scale Models has been the undisputed leader the world over in hand-poured resin and white metal detail castings. With emerging 3D Printing technology, SierraWest continues this tradition of unparalleled dedication to quality and innovation. Utilizing custom high-strength tooling resin, SWSM 3D Printed detail parts are very durable and easily handled. Supports are removed here in the shop so you can enjoy the painting and weathering process. Replacement parts are sent fast and free if you damage or lose a part. A small shipping and packaging fee may be added to cover costs. Be sure to check back often for the addition of new details.
Every attempt is made to keep the items listed for sale on this page in stock. Please allow between 3 and 10 business days to package and ship your order. Allow additional processing time for orders that are outside the USA and Canada. All items are in very limited quantities and once sold out the "add to cart" button will indicate "out of stock". Items will be restocked as time permits.

O Scale Single Blade Circular Husk

SierraWest Scale Models CHB Single Blade Circular Husk KitThe “husk” is the wooden and metal frame constructed to support the saw assembly. It is pictured here without the included saw blade. The husk is the main machine inside a circular mill and in addition to cutting the logs, controls the carriage drive and sawdust blower. The large drive wheel is visible and is powered directly from the overhead shaft drive. It in turns powers the shafts that controls the carriage drive and sawdust blower.
Includes White Metal, 3D Printed parts, and a laser cut sawblade. Brass wire and stripwood not included and are required to complete the kit. A list of these items are included. A link is provided in the kit to download detailed assembly instructions, drawings, and photographs.

O Scale Circular Husk - Second Blade Option

SierraWest Scale Models CHB Second Blade Circular Husk KitThe second circular blade is supported by the immense steel frame. It is driven by a secondary drive wheel installed on the main shaft. This “blade arbor” is driven directly by the overhead belt drive system and is attached to the operators lever. It in turn controls the direction of the log or “shotgun” carriage by way of paper and iron friction wheels. These wheels are maneuvered into position by the operator and control the direction and speed of the carriage. The husk builds into a beautiful model with all of the detail made famous by C.H.B. Models throughout the years. WP-900 (available above) is required to construct the double blade husk as pictured.
Includes White Metal, 3D Printed parts, and a laser cut sawblade. Brass wire and stripwood not included and are required to complete the kit. A list of these items are included. A link is provided in the kit to download detailed assembly instructions, drawings, and photographs.

O Scale The Carriage

SierraWest Scale Models CHB Sawmill Log Carriage KitThe circular husk, log carriage, and sawdust blower work together in unison. The carriage holds the logs while being cut. It travels upon a track back and forth passing the log through the blades. The adjustable “dogs” are very sharp and bite into the log holding it in place. Once the log is in place it is ratcheted and adjusted toward the blades by the log setter. He rides the carriage back and forth upon a platform. The machinery set is quite flexible as it works well for a small to medium sized mill. This gives you the freedom to design a mill to fit your space requirements.
Includes White Metal and 3D Printed parts. Brass wire and stripwood not included and are required to complete the kit. A list of these items are included. A link is provided in the kit to download detailed assembly instructions, drawings, and photographs.

O Scale Carriage Drive and Sawdust Blower

SierraWest Scale Models CHB Sawmill Carriage Drive and Sawdust Blower KitsBoth the carriage drive and sawdust blower are driven by the husk. These shafts can be seen in the photograph. The blowers intake duct is located near the blades to catch as much sawdust as possible. The discharge duct is connected to a burner or another type of disposal method. The log carriage is driven by the rope drum located directly under the track. This drum along with the rope sheaves moves the carriage along its track.
Includes White Metal and 3D Printed parts. Brass wire and stripwood not included and are required to complete the kit. A list of these items are included. A link is provided in the kit to download detailed assembly instructions, drawings, and photographs.

O Scale Live Rolls

SierraWest Scale Models CHB Sawmill Live Rolls KitAs a log is cut the “cant” falls onto the live rolls. These are powered and moves the heavy cant along to the cut off saw. The operator pulls the lever and makes the rolls turn. Beveled paper friction cones and an iron friction wheel control the speed and direction. One operator can control the live rolls and cut off saw.
Includes White Metal and 3D Printed parts. Brass wire and stripwood not included and are required to complete the kit. A list of these items are included. A link is provided in the kit to download detailed assembly instructions, drawings, and photographs.

O Scale Cut Off Saw and Dead Rolls

SierraWest Scale Models CHB Sawmill Cut Off Saw and Dead Rolls KitsThe cut off saw hangs from the roof joist and is driven directly from the overhead system. A tight and loose wheel are used together along with the drive wheel which is connected to the blade spindle. The tight wheel turns the shaft and the loose wheel simply spins. The belt strikers are used to transfer the belt between these two wheels. The operator brings a board in along the live rolls, positions it, then cuts it to a desired length. The small counterweight helps the operator cut the log. The freshly cut board is now sent along the dead rolls to the edger.
Includes White Metal, 3D Printed parts, and a laser cut sawblade. Brass wire and stripwood not included and are required to complete the kit. A list of these items are included. A link is provided in the kit to download detailed assembly instructions, drawings, and photographs.

O Scale Log Turner

SierraWest Scale Models CHB Sawmill Log Turner KitThe log turner is positioned over the log carriage near the husk and is responsible for turning the logs into their final cutting position. The head sawer is responsible for filling the mills orders and determines the positioning of the logs before each cut. Once again friction wheels and an over under belt arrangement are used to achieve operator control over direction and speed.
Includes White Metal and 3D Printed parts, and scale brass chain. Brass wire and stripwood not included and are required to complete the kit. A list of these items are included. A link is provided in the kit to download detailed assembly instructions, drawings, and photographs.

O Scale Log Deck

SierraWest Scale Models CHB Sawmill Log Deck KitThe log deck is a holding platform for logs waiting their turn on the carriage to be cut. The small steam powered cylinder, crank, and log stops work in unison to hold or release the logs onto the carriage as needed. Constructed of very heavy timbers, it is a formidable piece of the sawmill machinery puzzle. Not visible is a second steam powered cylinder attached vertically to one of the support beams. It controls a “kicker” which kicks the log off the “v” shaped skidway and onto the inclined rollway. The pictured logs are not included with these kits and are simply douglas fir tree branches.
Includes White Metal and 3D Printed parts. Brass wire and stripwood not included and are required to complete the kit. A list of these items are included. A link is provided in the kit to download detailed assembly instructions, drawings, and photographs.

O Scale Log Haul

SierraWest Scale Models CHB Sawmill Log Haul KitThe log haul is connected directly to the overhead belt drive system and is basically a series of gear reductions. An endless chain with sharp “dogs” positioned along the length is used to haul the logs up and out of the pond. The operator controls the ascent of the logs into the mill timing the rate with that of the cutting floors consumption of logs. The haul and deck are integral parts of the mill and are constructed together as one unit. You can clearly see how they are literally intertwined. The inclined portion of the haul that brings the logs out of the pond is not shown here. Plans and castings are included to build this portion of the haul as well.
Includes White Metal and 3D Printed parts, and scale brass chain. Brass wire and stripwood not included and are required to complete the kit. A list of these items are included. A link is provided in the kit to download detailed assembly instructions, drawings, and photographs.

O Scale The Edger

SierraWest Scale Models CHB Sawmill Log Edger KitThe edger or gang saw contains a series of five parallel blades located along a single shaft. The board after being chopped to length by the cut off saw rolls along the feed table and enters the edger. Here it is cut into individual boards. Since the saw blades may be adjusted, different board widths may be cut as desired. The finished boards are then sent to the discharge table. This is the end of the line and they can now be readied for transport to market. This type of machinery produces rough cut boards suitable for finishing in other mills or ready for use as bridge timbers, ties, mill or mine timbers, etc… The edger is driven directly from the overhead belt drive system. Complete plans are included in the manual for suggestions on arranging and driving the machinery.
Includes White Metal, 3D Printed parts, and laser cut sawblades. Brass wire and stripwood not included and are required to complete the kit. A list of these items are included. A link is provided in the kit to download detailed assembly instructions, drawings, and photographs.
