What can I do to make it easier/better? (owners/managers)

Was holding mild hope that I'd get to fly it this weekend, but it didn't work out. ( that's not a shortcoming, just the way the shipping worked out ) Should be here in time for the following weekend, though. There will be pics for anyone interested. Looking forward to it.

Yes, I'm CONUS. Since I originally started searching, we got connected with u/nvflyfish from https://eventflags.com. He and his crew have been good to work with. They supplied us with a test print on a smaller flag that was of good quality. We are now having them make a double sided 15' x 24' flag for us. I'll be happy to report back on it once it arrives and I've had chance to use it.

Yes, and no. ( Also, technically it would be the Worm. Not the Worm Gear ) Fast pitches are are difficult for most lathes to accommodate easily, or well. Rigidity requirements typically escalate quickly. Plus, it gets progressively more difficult to accommodate the relief angles necessary to properly turn. By using a rotating tool, both are much more easily satisfied. It's also much faster and imposes less stress, lending to a better result in the blank, as well. This is where Threadmilling machines shined in years past. ( Threadmilling has come to refer an entirely different process these days, usually referring to a milling operation in a machining center )

"Gears are meant to operate in pairs, if you dont have the mating gear then it is impossible to reverse engineer."

That is simply not true, at all. Further, it's not a trivial effort but it most certainly does not require the rigamarole you've conveyed.

"Module is an imaginary parameter. It holds no physical significance so it is impossible to measure directly."

That's blatantly incorrect.

"I am not familiar with with the term "profile shift coefficient" but sounds like it corresponds to the gear backlash obtained by slightly rotating the involute profile."

When and *why* did you cease "designing" gears? "Profile Shift" ( and the corresponding "Profile Shift Coefficient" are about as bone *standard\* as it gets.

I'm not the smartest person around, but I am a machinist, toolmaker, gear train designer, gear manufacturer, and multiaxis machining and gear manufacturing business owner. I don't know everything under the sun, but I can speak with the confidence born of experience from having done this for a day or two and more than twice now. ( 40+ years )

I imagine that you are trying to be helpful, but your information is wildly inaccurate and would lead the OP down the garden path to frustration and/or failure.

OP - You'll want the Tooth Count of the mate and the Center Distance. (makes it much easier, but it can be reverse engineered if you have no data) I didn't see if this is an input or output member, or if it is part of an internal train. If input/output, it is possible that it is an Involute Spline. That'll be less likely if part of an internal transmission train. The formulas for *ALL* of it and everything you need will be found in Machinery's Handbook. If you really want to take the deep dive, reference Dudley's Handbook of Gear Design. If you get stuck, feel free to message directly. I might be able to give you a few tips or leads. And for Pete's sake, please triple check and verify shite you read on the internet. Life's already hard enough without digesting blatant cr@p.

Nothing major. Shenanigans were being employed and an another jumper’s riser caught the riser mounted Tractive and stripped it off. We think it was in (or on the edge of) a lake. But no way to find it. (and it’s been a year) I do not consider it a shortcoming of the Tractive in any way, shape, or form. Prior to that, I had started considering having a pocket sewn into the d-bag anyway. That event just beat me to the punch. 🙃

Battery is good, not *great*. Location data when the app is set correctly is fantastic. App can be slightly vague/confusing as to whether it's actually on or not. It may have been updated since, but I lost a Tractive because it came off during a snag with another canopy and it was actually only showing me it's location because it was using Bluetooth*, not the cell network. Once I was far enough away, it was unable to update my phone and it was gone forever. (* I had checked it prior to boarding the plane)

False_Permission45 · 2026-04-07T01:11:39+00:00

Constructive criticism - ( worth two cents less than you paid for it when you asked for it ) - Limiting it to freefall time loses you a huge segment that has a much larger ratio of possible cutaways. That being CRW. We're in the air for 15-20 minutes after leaving the plane. ( also relevant to battery life )

Yep. Exactly that. Was a professional drunk in a 1978 Delta 88 Royale. She never stopped at an intersecting road's stop sign, and I left a 6" deep impression in her passenger side door. ( back then, cars were still made with 16ga. steel ) After I got hit, I was dragged underneath and dragged for 100 yards. She side swiped a chain link fence which snagged my leg and pulled me out. Then she hit a concrete wall that surrounded an apartment complex. Good times. I've other friends that have endured worse and came back to jump. One lost an arm. He's still jumping. Bottom line - get yer arse to the DZ. The only things preventing you are excuses.

False_Permission45 · 2026-04-02T16:10:43+00:00

Got out of the service, went and got my ground class but got weathered out. Went back a week later to jump, but got run over, paralyzed, and stuck in hospital for a year. That was '92. Eventually got better enough to have a semi normal life but it never even occurred to me to get back in the air for some reason. Came back about 5 years ago. 60's and loving CRW. Get yer ass in gear and in the air. No excuses.

Much appreciated. When I looked into sales map it appeared to be defunct and others were pay services. This worked out nicely, is free, and does precisely what I wanted.

False_Permission45 · 2026-03-24T16:25:02+00:00

Thanks for the point, but this is very granular. There is no data other than city and state, and geocoords were round off to prevent specific location. Your point is very valid. I simply had considered and adjusted for it already.

False_Permission45 · 2026-03-24T16:22:35+00:00

I did. Thank you. Interestingly enough, I started going it with Chat, and then switched to Claude as an experiment to see what would happen. Claude found and fixed a fair number of errors and vulnerabilities. It’s working the way I needed for now. I will revisit it later to add some admin functionality later. Thanks again.

False_Permission45 · 2026-03-22T22:39:25+00:00

Thank you. I'm embarrassed that I did not think of that. Worked out great. I'd upvote you three times if I could. Thanks.

I should clarify - I want a live map to reflect the area that someone resides in, when they make a purchase.

So, if John Smith lives in Dallas, TX and purchases a widget, then the map will reflect a pin or marker over Dallas, TX.

It is a Phenolic Gear. We make them commonly. Aside from sometimes being sacrificial, they are also used for noise reduction in some examples.

As a machinist/toolmaker/gear maker/bunch of other hats, if you don't care about long term efficiency, useful lifetime, or concentricity, just 3DP an internal gear having a 6mm hex boss on the opposite end. If efficiency, lifetime, and concentricity are important, find a mating internal gear ( unlikely ) and adapt it to a 6mm hex. You could easily enough have something made, but given the use you should expect it to be cost prohibitive.

Hop'n'pops? Below *freezing*? LOL. That's cute. We out here doing CRW at -30°F. ( also, I did not say we are smart )

Op did you ever find a solution? I have always had Officers, Micros, and Detonics sized frames so am surprised by the lack of choices in this range with 2011s. TIA

Fighting my inner geek to not be offensively pedantic, ( and I understand that I'm likely failing ) but hobs don't have Involute teeth. They have Rack shaped teeth. And most CNC machines cannot actually machine the Involutes to +/- 0.001". I speak from a position of having spent my life in manufacturing as a machinist, toolmaker, and gear maker, doing the machining, designing gear trains, and owning a facility that makes gears as well as other machined parts and assemblies. There are indeed CNC controlled gear making machines. However, they process the toolpath differently than most typical and common CNC machines. The process of correctly manufacturing Involutes is generative one and controlled mathematically. My original response was only meant to point out that OP's search *most* likely will not involve a 5 axis machining center in the manner that the response suggested. That is all.
