I apologize for any interruption in the questions being asked. I'm going to be as quick as possible with this. I wanted to post about the NOV 22 2018 motor first. Then, I'm planning on going pretty quickly through the 5 APR 15 2019 motors I have.
I have the procedure for trimming the pellet. It's 7 pages long. Just saying, so the vendor is going to sell someone a motor and direct them to this document. Verses, telling them that they could buy a AT G with no modifications necessary. And, if the buyer doesn't feel comfortable doing it themselves, the vendor is going to stop what they are doing and tend to this. Good luck with that.
Again, these are 29 mm, 3 grain, G33
Date Code: NOV 22 2018
Igniter: 2.39 x 2.56 mm at the solder connection to the head.
Nozzle: 2.78 mm at aft end of nozzle. It's smaller diameter at the forward end. (Photos)
Does the igniter pass thru the nozzle: Yes
It's very difficult to remove the grains from the liner. I used a 7/8" diameter wood dowel. This would be difficult to do in the field if you didn't have something like this dowel without damaging the grains.
Started to score the pellet after removal with 1/4" aluminum rod and it broke almost immediately. However, I was able to trim in down and re-insert it. Again, this would be difficult to do in the field. I'm in my shop with all my tools and materials, with no wind.
I drilled out the nozzle throat with a 7/64 drill bit so it was uniform. This motor will be static tested on October 3. May the Force be with me.
