Who sells 3/8" paper launch lugs?

[DeeRoc29]

Yeah I'm old fashioned. Not a fan of brass. Last pair I bought we're from Red Arrow Hobbies.

3/8 is not a common size launch lug. The common sizes are 1/8”, 3/16” and 1/4”. These can be found at most Rocketry related vendors. For stuff like that I usually buy from Rocketarium https://www.rocketarium.com/Build/Launch-Lugs

3/8" and 1/2" used to be fairly common before rails became popular.

Yeah, not a common size. 1/2" and 1/4" lugs available here:https://locprecision.com/product/launch-lugs/
Rather than use a big rod most of us now use a rail. Too many advantages over a 1/2" rod. Laters.

DeeRoc, I smiled and chuckled when I saw your request...LOVE IT! Hey, I still have a 3/4" lug on my second high power bird from the 90's! ...and 3/8" lugs on my L1/L2 bird from the same timeframe...though they were brass.

On a source note, I believe Semroc has or had something in that size range. I recall them at one time...maybe coming with the clone kit for the original Mark II. It was a thick wall big lug...larger than 1/4", smaller than 1/2". Let me search a bit...

Found it. Semroc P/N MC-522. I believe it is .5" OD x 2.25" long. It would qualify as a 3/8" lug, in my opinion.

Did the Esoteric fly? Looks great!!!

Make it,,,
Get a 3/8s dowel wrap some wax paper around it (for realise), cut up a cereal box wrap and glue Walla you've made a 3/8 lug
Easy-Peasy

 

[DeeRoc29]

Thanks everyone, and Eric for the Semroc source. I'll give those a try. I still use my own 3/8" rod on a couple of old birds.

Eric, yes the Eso flew great at NSL. Can't wait to crank it up at XPRS on 12K Ns.

Paper straws.

These are a bit larger than 3/8”. I use them regularly.

Because they are paper they glue easily with paper or wood glue and finish well

7.75 inches long, $5 for pack of fifty.

You could also use launch loops, just bump the wire size up to 0.062", and drill the body holes.

What he said ^

"T-4" tubing from Balsa Maching Service (also E-Rockets has similar). It's thin-walled and flimsy (like a smaller version of a BT-5). BUT, you can wrap 3/4 oz or 1.4 oz fiberglass cloth around it a few times, brushing on thin epoxy as you go, and make it as sturdy as you want to. I do it with a tube way longer than needed for the lugs (always some scrap near the ends), and then cut to lengths after.

I am about to leave for work but I did have time to check my stash of stuff. I have a couple of sets of Acme Conformal Launch lugs new in the package. Private message me and I can send you a picture.

 

[Brent]

Here is a picture of the two sets of Acme Conformal Lugs. They can be made to fit other tubes. Let me know if you are interested.

Thanks Brent, but I'm good now.
