SAI Hen Grenade Plans
While searching for my folder of Estes decal sheets (I've lost the whole folder and haven't been able to find it for two months!) I came across a set of plans for the old Space Age Industries Hen Grenade. I recalled that someone had been looking for these and did a search..............turns out it was Arley Davis, so Arley, if you're still looking for these, let me know and I'll scan them for you. Scott, if you need a set for your archive please let me know and I'll send the scans to you too.

Thanks, Joe! Yes, we can use those plans on YORP as well.

OK, Scott. It won't happen today, but I'll get them scanned and forwarded to you as soon as I can. Should I email the scans directly to you?

Well, I'm sorta looking for them, too, as I still have tubes from the original kit, but I'm in no particular hurry so I'll just wait on you to send them to Scott and for him to post them.

Roy, Joe got the plans scanned today so I sent him my email address to send them to. I'll forward them on to you. Could you write up a doc file listing the parts you have with dimensions and send that over to me?

Thanks Joe,
The next question is: Where the heck do we find 45mm (1.77") body tubes? Totally Tubular (the supplier with the widest range of odd tubes) does not carry this. The closest that I can find is Centuri ST-18 which is 1.84" in diameter..... Any ideas? Phred

Phred:
I'm going with the ST-18. It's slightly larger at 1.84" OD, but I'm going to construct my payload/nose cone section from heavy card stock to ensure a strong compartment for the egg, and using the shroud pattern provided means that my part will be slightly oversize due to the thickness of the card stock. So all my parts will be available from Semroc, including the coupler for the payload section. This probably seems like blasphemy to the purist, but I can't get too hung up on a difference of .07" in diameter. Joe |

I should have asked this in my last post...............are there decals available for the Hen Grenade? Joe |

Hi Joe,
I guess I would have to agree, both the ST-18 tube and coupler should work from Semroc. Althought the decals are not yet finished, I plan on working up a set. Question: Should they be in white, or yellow? Ph

Well, Phred, I'm not terribly artistic, but if I get a vote I'll go with yellow (with black 'H' and 'G' in the two white eggs). Judging from the drawing of the Hen Grenade lifting off on page 1 of the plans, and using a body tube length of 11" (not counting the payload section), it looks like the decal had a length of about 5-6". So I'm wondering if the kit name at the top of the plans on page 1 isn't just about exactly right for the decal lettering?
