How much play is there with the inner signal tube?
A layer or two of fine kapton tape for a snug fit to remove any play and further insulate it from the body/ keep it perfectly centered?
One layer of kapton tape was all I could fit. Any more than that and it won’t fit into the outer tube any more.
I don’t know if the tail parts will be glued or not, so I don’t know how easy it’ll be to open. Regardless, that doesn’t seem to be an issue as much as making sure the driver fits into the proper place. Proto1 and proto2 were totally fine in that regard, I never saw a proto3, and proto4 didn’t have quite a large enough space cleared out for the driver.
Detailed info has been sent, but everyone there is on holiday for a while so there is no response yet.
Cool. I’m guessing there is a retaining lip at the switch end of the tube?
Yes the driver cavity being correctly machined is quite an important aspect of this build.
I don’t think there was ever an issue of the battery tube being too short. There were however instances of the driver not sitting down into the driver cavity all the way which thereby made it seem like the battery tube was too short. Maybe that is what you’re referring to. And yes, this issue has been relayed back to the manufacturer.
