The Manufacturers Page
Can We Help You With Your Model Mechanism Needs?
This section is intended for manufacturers only. The mechanisms described here are not for sale to individual modelers.
Hollywood Foundry can make special mechanisms based on our BullAnt components to suit most manufacturers requirements. There are already many mechanisms being supplied to manufacturers around the world that we have created to their needs.
And there is no need to acknowledge our involvement in your design, we are quite happy for you to promote and market the mechanism as your own.
At the simplest, we have a wholesale pricing scheme for small manufacturers who only need a small quantity of standard BullAnts or parts for their models. There are no minimum quantities for orders, we just ask that you are honest about your manufacturing status.
We offer a fast response to your enquiry and rapid design turnaround, depending upon the complexity of the project. As well as the mechanism itself, we can apply a knowledge of electronics to the project as well. We have, in the past, created chassis units with an NMRA standard DCC socket ready for fitting of a decoder, constant brightness directional lighting circuits and our own Stored Energy Lighting Units.
The procedures for working with us to produce a design are explained at the end of this page.
R-T-R Diesel Mechanism
We are currently offering a service to supply a complete mechanism based on our In-Line bogie. The base plate or chassis section is a printed circuit board cut to your exact size with two In-Line bogies, a choice of motors and flywheels, all coupling shafts and hardware in an RTR mechanism.
The mechanism pictured is a Co-Co design for a 3' 6" gauge diesel locomotive, modeled in HO scale. The gauge of the unit is 12mm, with axles spaced at 22.3mm. Solid nickel silver wheels of 11.6mm diameter, Code 88 are fitted. The bogie centres are 113.1mm (representing 32 feet 3 3/4"). The overall height of the mechanism is 30mm from rail. The drive ratio is 26:1 and provides serious pulling power with a scale top speed of approximately 83 KPH or 51 MPH. All wheels are driven, and all wheels collect current.
The custom printed circuit board is made to fit your model and can be fitted with an NMRA socket for DCC, and a variety of lighting options, depending upon size. Designs may have unusual shapes such that your body can fit directly to the chassis. You can specify mounting points for extras such as under floor detail, fuel tanks, battery boxes and the like. Lighting can be fitted directly to the chassis board if you wish.
The Design Procedure for a PCB Chassis
Hollywood Foundry will design the PCB chassis to suit your model. This process takes approximately 1 month from start of design to production of the first PCB's. Each custom designed printed circuit board is subject to minimum quantities. The smallest run of boards that can be produced is one panel, approximately 12" x 18" in size. This would normally make anything from 10 to 30 boards depending upon the size and complexity of the design.
A single panel currently costs around A$406.00 to produce because of the phototools required to produce the design. We do not make these panels ourselves, but get them made for us by a PCB company. We therefore have no control over the cost of production, and we do not profit from this process, passing on the PCB manufacturer's costs without markup.
Once the design is settled, each panel is made at a substantially lower cost. We ask that you pay the cost of production of the original panel, and a cost for each mechanism produced from that design.
It is important to get the design correct, otherwise a second version may be required, and that will cost a further A$406.00 to produce. We are not keen to produce designs from drawings or sketches, the most reliable method is to measure up the actual body that you will be placing on the mechanism.
Initially we would like to see a dimensioned prototype drawing of the model. From this we will produce a scale dimensioned drawing of the mechanism for you to approve. Then we need the body to fit to the chassis. Once the design is finalised, we will have the boards made and then provide a single mechanism for your approval before making a batch.
We cannot produce sample mechanisms as the number of hours required would make them prohibitively expensive. But you are welcome to order In-Line bogies plus motors, mount etc. and try out the design yourself.
If we can help, or even if you would just like to discuss your project, please contact us.
