Here is how I currently manage Mimeo 1 kit availability.
In order to keep costs down, I restock component parts only when I run low or completely out of parts. Number of kits available, depends upon if I just ran out of some component or another, and how low the inventory is of all the rest of the required components. Keep in mind that there are 69 different component types in a Mimeo, so I’m usually running low on something. I rarely have on hand complete part kits for more than 3 or 4 units at a time. Frequently I’m down to one or two kits of parts on hand. The good news is that most part types can be restocked within a month.
Even though the volume of kits sold is very low, this process is very time consuming. Just as bad for me, the effort required is very dependent on the frequency and timing of Mimeo 1 kit purchases. This makes it very hard to make consistent progress on new projects (like the Scelbi).
I would love to move to a batch system, but component availability is so erratic for some of the more hard to find components, that often I will jump on an opportunity to buy a cache of those components at a good price. This makes putting together batches of kits hard to do, since the size of inventory of the various component types is all over the map. Instead of making batches, starting next year, I’ll will probably be less aggressive about keeping Mimeo kits available, especially if I’m busy with a new project. So what I’m saying is that starting next year, Mimeo kits are just as likely to be out of stock as in stock. And they may stay out of stock for a while, if I’m busy trying to make progress on a new project.
