I was going to install an eyebolt into the fore CR in a LOC IV... I
went tot he hardware store, and I'm having trouble deciding between
the 1/8" and 3/16" quick links, and the 3/16" and 1/4" eye bolts. The
larger of the two feels pretty heavy, but i was wondering if anyone
had any luck/recommendations. Is the smaller gear any more of a pain
to open/close while it's installed?

This rocket will probably only see G motors, maybe an H123 if I ever
go for cert. I'd like to keep things relatively light.

I'm totally nitpicking!

The 3/16 eyebolt and 3/16" quick link will work well with the LOC IV.
However, if you want more bearing surface, replace the eyebolt with a
small 3/16" or 1/4" u-bolt. Sometimes the single centering rings are on
the thin side and increasing the overall bearing surface will help keep
the recovery shock cord assembly mount from pulling loose an separating,
if motor ejection comes early or late.

If you want I'll put a picture of an assembled 4" LOC centering
ring/ubolt assembly on alt.binaries.models.rockets; just happen to have
one put together.

Pictures; both sides is already posted to alt. binaries. I used a 1/4-20
x 1&3/8" u-bolt. You can find thease in most hardware stores. You can
also use larger u-blots, but I would try and keep the thread size to
1/4-20 and mounted to the side, just in case you want to use a longer
motor..(:-)
