Question – Does anyone have a 3/8″ lifting eye similar to the one at http://www.bosunsupplies.com/products2.cfm?product=S0322 ?
I *might* need to borrow one on Sunday of MHM. I have three of these (or ones very similar) and I have a Sunday project that will take all three… I hope to fly a different project on Friday or Saturday that will also take one. Just in case I lose my Friday-Saturday project, I don’t want to be high and dry on Sunday.
Does anyone carry these honkers locally? I can’t remember where I got mine? If someone has a spare, that would be awesome…

JW, thanks to your recommendation, I bought six, it’s yours. 😉 Then again, mine were $9 and change each, right dimensions… from the link you gave me, did the price go up? I’lll pass one on to Art in case I can’t make it to MHM… though Hell hasn’t frozen over yet.
Addendum: Checked the site, mine aren’t forged, closed, yes, forged no, and that explains the price difference… drat! Still yours though. Have I said “though” enough?
Checked the site again, mine are stainless steel… couldn’t find the forged, stainless steel isn’t bad. 8)

Awesome, Bruce – many thanks. Those things are wonderful, I use them on all my rockets anymore. I just don’t have enough to equip two large rockets… I have them in 1/4″, 5/16″, and 3/8″. BTW, the cool kids use titanium http://www.bosunsupplies.com/products2.cfm?product=T0571 😯
What do you mean “if you don’t make it to MHM”????????

I’m just using stainless – I have 4 in 1/2″, 4 in 1/4″… I’ll be adding 3/8″ when I start my 4″ MD project. Bosun Supply is great and the prices beat the hell out of McMaster-Carr.

Bosun Supply is great and the prices beat the hell out of McMaster-Carr.
I’m not sure how you figure that Warren. Price on these items is
Bosun 3/8″
$20.13 rated at 1160 pound
McMaster 3/8″
$21.70 rated at 1800 poundBosun 1/2″
$30.56 rated at 2150 pound
McMaster 1/2″
$35.38 rated at 3600 poundSure you could save a few dollars but that’s hardly what I would call the prices “beat the hell” out of McMaster, especially when you look at the load ratings.

I just bought four 1/2″ stainless, non-forged eye-nuts with a 2000# WLL for $10.33 each. Based on the load rating, I’d say that beats the price of the nearest McMaster equivalent by quite a bit.

I buy my eyenuts from CD Fasteners in Fort Collins. I think when I bought some 3/8″ ones they were $6 apiece. I’m betting most of the time the harness fails before the eyenut.

I concur. Another area that I have had issues with is when I use a Kodson / AMW casing and I anchor directly into the fwd closure. My rocket “Argos” apparently experience a bit too much opening shock one time, and the upper end of the casing got a bit disfigured. The snap ring did not fail, but I had to chop the casing back. That really surprised me.
At the end of the day, as you say – the harness (and probably the chute) would seem to be the weaker links.
Love those eyenuts………

JW, I put two aside for you. I’ll be at MHM, just maybe not Friday–when the cool kids fly. Don’t know how my schedule will be then.

Just so most know I have a pretty extensive amount of hardware pieces like these forged eye nuts and eye bolts I keep around. If ever any of you need some please feel free to give me a shout.
