CUSTOM LADDERS AVAILABLE HERE: http://www.bricklink.com/store.asp?p=zephyr After developing the custom steam engine rods, I have now started to add other custom parts that are missing from the Lego universe. In this case they are 1xN ladders (or bars). These are fabricated in black, the surface is matte so they will not be mistaken for shiny bricks. If anything, they care closer to the surface of some Lego bars, e.g., http://img.bricklink.com/P/11/6020.gif Like the driver rods, other configurations are feasible, contact me via BL messages and we can discuss (I can't guarantee that I can make everything, and in any event, expect a longer lead time on new parts since I will have to design it). I can also fabricate these in light gray (same color as the drive rods) upon request. There are several fixed costs per fabrication run, so to keep costs down I will do a batch production job based on the paid orders (I anticipate doing so about once a month, but I will contact any active paid orders in the event of unforeseen complications). Production takes 2-3 weeks. As a result, the time between placing your order and standard shipping should range between 3- 6 weeks. You can expedite your production by choosing that option on checkout- in which case, I will break from my cycle and will begin fabrication immediately (still expect 2-3 weeks before shipping to account for the production time).
