I know because I was looking for 7.5" ones to match my 7.5" nose cones and found some. I guess they figure people won't care about a 1/2" off or so on a concrete piling.
I found three. It's the smallest of the set that are 7.5". It fits a LOC 7.5" nose cone (as well as my Polecat 7.5 V2 nose cone); however the tubing is thicker.Wow, you found one to match a nose cone?
I also ordered some Sig canopies (used in this Fat Cat F104 kit) so I can make a copy as backup and also a larger one for a 4" HP upscale if the usual 3" kit build goes well. Apparently it's quite hard to find them and shipping costs about as much as the item. Ouch.Yesterday and early this morning I dug up my old Fat Cat F104 Starfighter rocket to review in anticipation of building it in the next few weeks.
Initially I was quite dismayed to not find directions (and even tried replying to a 2015 email inquiring), but later located them inside a body tube.

Got my L1! Was a rocketry goal of mine for 2022, now achieved with two weeks to spare!
To that end, a big thanks to Adam who led me through the cert process, and to everyone else at NOVAAR. Very nice folks who ran a safe, efficient, and fun launch for all ages and skill levels. Will definitely be back in the new year.
Tomorrow is someday. So is today. Just sayin'.
All I can find in current distribution is this: https://www.lowes.com/pd/3M-Patch-Plus-Primer-8-fl-oz-White-Patching-Compound/3851673
Is it the same stuff?
Measure the diameter first since it may not be 8". For example, Lowes (and I believe Home Depot) have their 8" sonotubes arrive 3 nested inside each other...how? They vary in diameter.

Made some plywood centering rings
Several things all at once.what gives
wow, that's a lot to disrupt rocketry for sure. hope your surgery is a success.Several things all at once.
Mrs, after 7 years in our new home has finally purchased furniture for the dining room and formal living room. My “rocket room” was the dining room.
Father in Law will be moving in with us next week until the war in Ukraine is over and he can return home.
The osteoarthritis in my left thumb and the extreme associated pain has now necessitated ligament reconstruction of the CMC joint. This will happen week or so after new year. Surgeon say count on being in a cast up to 12 weeks. Shortly after that has healed I will get the right hand worked on. That surgery will be hematoma and distraction of the trapezium bone of the wrist. It is all but obliterated. It hurts too, but not nearly as bad as the left thumb! Again a few weeks in a cast.
All of his boils down to…..no rockets in m future. As Arnold says though, ”I”ll be back!”
Thanks, I hope so as well! That left thumb pain shoots all the way up past the elbow!wow, that's a lot to disrupt rocketry for sure. hope your surgery is a success.
R&L Electronics. Their shop got thumbs up from several YouTubers as place to get a good one. Well, good for the price. This is the one I bought: https://store2.rlham.com/shop/catalog/product_info.php?products_id=75669where did you buy it?
nice model, I thought they were all in the $50 rangeR&L Electronics. Their shop got thumbs up from several YouTubers as place to get a good one. Well, good for the price. This is the one I bought: https://store2.rlham.com/shop/catalog/product_info.php?products_id=75669
It came with an SMA calibration set. I don't have a mega-dollar one to compare it against, but it should be way plenty to do what I need.
I tested a cheap ($8!) ADS-B antenna first. The VNA showed its peak off by about 23MHz, but still showed a pretty good results. (You know, for an $8 antenna.) I swapped to this antenna yesterday for my Raspberry Pi ADS-B receiver and the aircraft position reports over the last 24 hours were more than double the last few Saturday's. Cool to see big improvements just off of an rx antenna swap.
I'll start testing 433 & 915MHz antennas for my rocketry projects soon.

There are definitely some in that range. This one (and the seller) seemed to be popular among people smarter than me, so that's what I went with.nice model, I thought they were all in the $50 range
Nice! Totally agree about building antennas without one. Nothing but pain down that road.I pulled mine out today and checked it out! First time in 2 years and it was still dead on...
WOW, nice, you da man.I pre-ordered a new 3D printer for my rocketry use, it is the Creality Ender 5 S1:
Tried out a new Dremel circle cutter to make a 54mm hole in a bulkhead for a custom fin jig I'm making.
