Just glued the N10,000 together, along with my hands, my hair, 362 paper towels, my workbench, my favorite pair of reading glasses, and somehow my left shoe.
Carl, i'm also flying one of those too....LOVE that motor. Some constructive advice here (since i'm *done* telling Dixie to eat more Fiber One Cereal).
The first thing i do is knock the insulating end cap off by inserting a large dowel or pvc pipe into the liner...and, put it off to the side.
I've found that using a flat topped sawhorse works the best for holding the liner when i glue up any of my bigger CTI motors. The next thing i do is strap the liner to the sawhorse with two bungee straps, leaving about 3-4 inches of overhang on the nozzle end.
I like to run a flapper wheel i have on a large threaded rod up and, down the bore for a few minutes, even if it has been pre-scruffed by CTI.
Blow out the bore with human created air pressure or a slight amount of compressed air.
Unpackage your grain spacer o-rings and, grains... inspect for any irregularities...
Put a small trash bag, plastic sheet, or wax paper directly below where the nozzle end is...
Using whatever glue (Elmers, Gorilla, or even West Systems Epoxy as i do...) wet down the first half of the first grain with a chip brush and, insert slightly into the bore.
TWIST the grain and, liberally wipe your chosen glue on the grain at the point where it is going into the liner. It's a going to get a sloppy here...
Run that grain fully into the bore about 1-2 inches and, insert a grain spacing o-ring. Now pre wet the next grain casting tube slightly and, do the same for number 2.
By the time i get to grain number 4-6 i'm already starting to get a little more sloppy...That's what the drop cloth is for.
After i get all the grains in i insert the nozzle and, wipe the area around the joint with rubbing alcohol to clean up any excess. Make sure you wrap a little blue/masking tape around the line to seal it up. Insert the end insulating cap and, run a piece of tape over the top.
Holding the liner carefully unbungee and, put in an upright position for at least 24 hours on some wax paper to let the glue gravitate down the inside of the liner.
After 24 hours i put together the starter grain package into the forward bulkhead, grease the o-rings, and, put a little grease on the forward end of the liner...insert into casing. Put a little grease on the threading of the case rings and, tighten down. put your Cap-plug on the nozzle to keep moisture out and, VIOLA!
DISCLAIMER: The use of West Systems Epoxy VOIDS all warranties....(It works for me) Use rubber gloves and, properly dispose of all glue/epoxy cups...brushes...etc in a smart manner.
I've glued up over 20 N-10,000's, O-3400's, N-5800's, N-3301's, N-3400's, N-4100's and, N-5600's using this method (glue wise) and, never had a failure yet....As a matter of fact i find alot of casting tube residue still attached to the liner when i clean my motors out.
This method is simple and, works for me. The key is securing the liner to something to free up your hands while you work and, producing LESS MESS.
Good luck at the launch!
