Currently, we have standard frames and tanks in stock. What that means is that we have the fabricated parts such as frames, tanks, etc. in stock and ready for assembly, which is a big shift from the way we did things before. That shift is, in essence, to cut the time of production by cutting fabrication wait- time. The way we've done that is to stock those parts, vs. ordering them on an as- needed basis.
This is common- sense, I know. But because we make so many models of systems, keeping that many models in stock simply isn't practical. Some systems we sell very few of, while others seem to "pulse" in sales, compared to each other, so it's difficult to predict exactly what the next likely order will be- and therefore, which systems to have at the ready.
We do have some systems in stock. But even for those we don't, we can assemble them when ordered within 3 days of the order.
Previously, our frames were made by the same fabricator we've used since 2002. But about a year and a half or so ago, we pulled the system frame fabrication from them and went more or less, "in- house" with it- which is why our turnaround time got so much faster (3 days on average) for system frames. This was done by having the same fabricator make frame parts on the CNC machine (no loss of quality- no change of design in any way), but us doing the welding. We are in the process of doing the same thing with the aluminum welding, which will complete the goal of reducing production time.
What does take time, and at times can be a serious strain on patience- is when custom orders are placed for items that we do not, or have never, produced. In such cases, the items in question typically have to be designed by me, then submitted to the fabricator and put into their production line. They don't get excited about "one-sies" as they call it, so they typically see single- item orders as kind of a nuisance that they do as side- work. (They're done almost as a "favor", in other words.) So there can be a gap there that can't be forced, as much as I'd like other-wise.
