I just finished my time alignment tool.
I built this heavy stand in order to keep in position 1" and 2" compression driver unit with dedicated horn. Basically it can be used with every midrange unit.
The purpose of this tool is to have an accurate control over time alignment and spatial position of the driver. It could be used on every large size bass speaker.
My purpose was to have the following settings:
- long stroke time alignment (delay)
- full adjustable feet, height, camber
- rotating tower
- translating slide left right.
Coupling: cork discs between driver unit and brass. Steel balls from a bearing, with dedicated brass support.
Materials: Brass, soft aluminum, 7075, stainless threaded bars M10. All screws stainless. I decided engine turning for the front plate.
I will engrave in the future vernier style graduated scale. A next improvement could be a remote controlled unit, with motors instead of knobs.
I'm traditionalist, I prefer manual action mechanisms.
I upload a couple of pictures of the unit, I don't know why but I can't use the automatic loader, I have to put one picture each time.
That's the link of my FB album, with full construction if someone is interested.
