Re: Mike's Build Log
So, I've got the 5 fueling access ports tapped and pluggable, and now I'm down to selecting the fueling hole diameter that will shoot inward at a 45 deg angle. Too big and I can't fix it, so I'm torn. pjsls full.PNG pjsls cutaway.PNG I've taken to thinking I want tiny holes, but stiff jets seems dis...

Re: Mike's Build Log
Yeah, I’ll do a few tests at nipping it to make a Rosscojector, but when you think about the area we are talking, the holes i was experimenting with were around .5mm. A nip or slit just seems too hard to replicate, or hit any specific area in production. Maybe it’s not that finicky…. I’m pointing do...

Re: Mike's Build Log
Well, only one didn't have support material in the CC. And the fueling holes are clogged with support material too. I’ve gotten it just far enough to try the starting stinger: 8DE4670B-F8B0-4F55-93F6-8604E9BBCCD0.jpeg Need to find my dinky drills. I think a good starting point for this stinger is .5...

Re: Mike's Build Log
Ship from China, customs, 3-5 days travel time, 6 months? ha
We shall see when they arrive.
Then it's fuel holes, tapping holes, sorting out the instant start stinger, etc.
I can't wait to fire it up!

Re: Mike's Build Log
Oh, someday we will molecularly print ALL materials, in hitherto unknown alloys and densities, and a host of disciplines will die.

Re: Mike's Build Log
Getting there, here is a pic of the parts after printing. They will be removing support material, welding and finishing soon.

Re: Mike's Build Log
Actually there’s 5 fuel ports, as I couldn’t get access to drill 6.

Re: Mike's Build Log
The six ports on the head are so I can drill six fueling holes into the CC, the one on the front u-bend is for an instant start fuel stinger. The six ports are to be tapped and plugged, with one selected as the main fuel feed. The augmenters will look like this: 0EE929F3-94B6-4B1A-8E1B-729602C7D066....

Re: Mike's Build Log
I think it’s SLS. They originally balked at 1mm wall, but I told them they could weld any voids. Then the plan is to print in a few pieces and weld together. We shall see…
