Here is a quick walk around of my system, its not totally complete, I'm still waiting on some wiring harnesses and some plumbing fittings. Any input or suggestions will be appreciated!
Setup looks clean.
For the narrower angle nozzle request (30°). We've been working through stuff on our side a fair bit, and found that the smaller the nozzle (especially if it is a drift reduction nozzle), the tougher it is for the nozzle to apply consistently in the desired pattern. For sizes <02, around the 20°-25°, it starts to have a good chance to stream instead of spray in a nice clean pattern. For a 30° in an -02 size, probably wouldn't be too bad, but it'd be something as far as a limitation of flat fan and even fan nozzles in those sizes, with the drift reduction throwing another wrench in the mix.
For the harnesses down to the nozzle, if the zip-tying was going to be causing grief since you have a bit of span there, we did just make new tooling to have a boom clamp that provides a bolt-mount to it, that might be helpful in keeping things taut enough without chancing wrecking for your wiring. At least then you'd have a common platform (1/4" bolt) for a whole lot of cable ties and such.
Its nothing too crazy special and there'd be alternatives out there, but given the importance of the harnessing, might be worth looking at over zip ties.
For the weedit sensor locations, is it fairly easy to modify individual sensor distances? Thinking of the two that are sandwiched between the frame up front, is the look-ahead for individual sensors editable? And you mentioned there is a MAX distance to follow, which seems a bit odd as it'd just be a longer look ahead. Seems like something that would be easy enough to change, but I get the system works better with them relatively closer in turning situations/etc to minimize misses.
I like the boom layout. We've worked with Croplands for the 10" boom kits, and yeah, it is tight for sure. If it does become too much grief, there is always the option to add a boom end nozzle body as well. I know some of them would shorten that a great deal. Probably not so much an issue on a 67XL as it is wide open in the back, but WAY more important for guys who are installing on a pommier/millenium/specialty boom. The amount of cross bar structures and frame thickness makes it a nightmare on 10" spacing, which means a lot of remote nozzle bodies which I kind of hate.
For that specific tight spot, this is a new part that should be available in the next little bit that we designed for that narrow spacing recirc sprayer section as well. The solenoid would then go either OUT, or IN depending on which elbow you set up. The clamp built-in is a Wilger only clamp, but we do make a triple body with teejet outlets if that was a need. (Only the solenoid would have to be the Wilger WEEDIT solenoid thought, as the module threads between manufacturers is different)
I might worry about the tubing for the tie-back recirc side of things, but I figured you'd maybe be doing that temporarily? Just a bit of kink in the line that the hose wouldn't like eventually. Probably just swap the fittings to a flanged tee with two 90s pointing up to sort that out. I'd imagine there might be some merit to having that tee as a sweep tee to clean up the flow path a bit as well.
All in all, looks good. I have heard good things about the helix filters for sure, just a bit $$, but probably worth it in the long run. What would a filter of that size cost nowadays, do you remember?
. And I was probably tooting my own horn too much for some of the parts, but I'd reckon the Banjos/Teejets/etc would have most of the alternative parts as well.
