Talked to the machine shop today. There is good news, and some not so good news.
The good news is that it's not a big deal to make. The new version of the Shiftster, now known as the 'ShiftHappens,' will be a bit different than the original - current design revision will have a one piece CNC cut handle and rotor shaft all made from aluminum. Doing it this way will cut down on final assembly on my end, and hopefully lead to increased durability, etc. Neutral detent will be a feature as well. Still the same idea with a baseplate and spring loaded knob for locking in the correct position. Current plan is to ship as a finished unit with three bolts so that the swap is simple and it can be carried as a kit. Might include a convenient pouch, might not depending on cost.
The 'neutral' news is that increases in material costs and using all american parts and labor is going to lead to a slightly higher price point, around $129 per unit. I can probably get that lower, but will have to sacrifice the "Made in USA" stamp, which I'm not sure I'm willing to do.
The not so good news is that they want to do an initial run of 100-150 units. Not sure if the market is there for them. Unknown.
Comments appreciated.
