I’m currently putting the finishing touches on the M 500 hybrid. Right now it’s 98mm and burns for 12-15 seconds. And it’s shiny. Did I mention it’s shiny? I’ve got to sway you over to the dark side Conway….Edward

Con,Yes, Jim A has a quiet way of motivating and guiding us in the direction of greater power, more sophisticated projects, etc. He’s the guy who got me thinking about a big balls projects, and still harasses me to the…   Read more»

He still does the courses. Next time he calls me or I call him I will ask for sure and when the timelines are. Jim Amos is who first sparked my direction and then the introduction to John Wickman. That…   Read more»

Wickman’s was the first book I read on the subject–would love to go up to Casper for his course if he ever starts doing those again.As to long burns, I corresponded with Tony a while back for ideas re c-slot…   Read more»

My first dive into Research was origanally with ANCP motors from the formulas based from Wickman. (BTW one cool dude very smart and glad ive gotten to know him pretty well.) WR is a great formula to use pretty color…   Read more»

Con,I’m still a newbie to research, all i’ve ever done is WR (russell/woody recipe), but I’m open to trying some new recipes. Also I’d like to try vacuum degassing to get the density up, and voids out. I was really…   Read more»

James,The nozzle is out, that was easy. Its the liner. I’ve got a couple days off and with the impending snow dump, likely nowhere to go. So I’ll give Ed’s idea a try and see what happens.JS

first of all have you got the nozzle out? if not use a broom handle to push from the inside to get it out but be sure someone has a hand on it when it brakes loose. you do not…   Read more»

Ed,for the mechanically challenged like myself–let me dbl check what you have in mind. The forward closure with O-ring seats against the stuck liner facing backwards rfrom its normal orientation so that a length of all-thread runs the length of…   Read more»

Just read this and thought of an idea that might work to get the liner started to budge for the next time around. Take the forward closure (I’m assuming that it is tapped) and flip it around with the o-ring…   Read more»

Con,Thanks for the help, I’m definitely changing to the slather it with lots of lube camp for future flights–I have some high temp grease I bought from either forefox or aeroconn which I’ll start using as I’m out of the…   Read more»

As far as grease I use the Lucas products grease good to 550+ drop point. Just got james some. Others will work as long as the drop point is high enough. And yes I recomend using a bit more then…   Read more»

Con,Grease? The red stuff James R uses–think its a synthetic automobile product–and not enuf apparently–and I have been curious about this being something of a newbie–I see guys slather entire lining with grease, but all the instructions I ever see…   Read more»

First off what Grease was used in the assembly and how much grease did you use. Im a bit of a heavier user of a Good 550 degree capable grease but makes for an easy clean up.Actually here is somehting…   Read more»

John,Yes its phenolic–several hours of soak did little to the motor but discolored the bathtub. It wasn’t soapy, tho. And my first proper caveman instinct was pull the o-rings off the forward closure, and beat that sucker out. All I…   Read more»

What kind of liner? We have soaked liners that are stuck in casings in soapy water with great success…. takes a day or two, but it generally works — IF the liner is not phenolic, which doesn’t absorb water.I’ve also…   Read more»

My wife is drooling over the machine so rest assured it’s a good machine. Right now we’re up to 5 sewing machines including 2 sergers…Warren

It Looks coplicated to me, 4 spools!!!hmmmm

Ha! Well, when I asked my wife if she would make a few chutes for me, she knew how few that wouldn’t be, and she said no, but she’d teach me how to use her machines. One, a heavy-duty programmable,…   Read more»

Last chute was 12 feet and it worked fine just using parachute cord from the army-navy surplus.John SYou can bet your life on that surplus parachute chord! I have. It is the same stuff actually used on the Army’s parachutes….   Read more»
