    I started a resin print of my recreation of the Roc-a-Chute Mark II nose. I'm going to start another big test print of an Aero-Pad leg after supper.

    BTW, how do you handle resin fluid inside a PNC? I'm thinking about adding a drain hole in the tip and a vent hole in side of the tenon.

    OT: I'm going to be interviewed by Zinc Comics at 8 CDT tonight. https://www.youtube.com/channel/UCwa3sBS4O9lJsD69e4PV4KQ

    Finished this up. Gonna let the decals dry for a bit then flat clear coat. A bit of weathering after that perhaps...

    My most successful weathering technique involve flying the rocket a couple times :cool:

    In addition to fill a bunch of orders (thanks guys) I got the sacrificial paint on the Falcon 75 a step closer to done.

    I finished assembling the sr71 and finally got my temporary launch pad assembled for my mid power rockets. I also managed my first g launch of my initiator.

    Just finished up measuring and making a OR file for a built TLP Nike Ajax kit I borrowed in hopes of eventually cloning it.

    Painting in the last but of favorable weather before rain descends on rocket city. May be just me, but this looks kinda funny

    *edit: incidentally, there is now a very angry spider on my deck. Probably has something to do with being spray painted half red

    What's the process for cutting or sanding down the nose cones to fit like that?

    Split nose cones in half.
    Wrap sandpaper around body tube and sand sand sand.
    Stop, check fit of shoulder in booster tube.

    Put the first color coat on my 4" PML AMRAAM. This will be my level 2 rocket, if I can ever finish it.

    Interesting coincidence. I was at the BSRA (Big Sky Rocketry Assn) launch yesterday and the advisor and team were down from Lame Deer Tribal College to do some filming to promote rocketry in their community and test fly their scratch built rocket on an M. They have been involved with the First Nations Launch Competition. The flight was nominal with good recovery. I launched a saucer to show them base drag stabilization which they found interesting but odd. :) Long drive for them, but I think they enjoyed the launch.

    Picked this up at Hobby Lobby yesterday. It must be the HL exclusive version of the Sterling Silver. All of the part numbers are the same for the two kits, only the instruction sheet and face card differ.

    If you haven't seen either one, they are 18mm minimum diameter two stagers. Would be easy to lose on C6s! Streamer recovery may help a bit...

    Cool looking rocket for a TFNC, I think. Or is it a SFNC?:confused:

    My five year old daughter wanted to know what I was doing on the computer so I showed her Open Rocket. We built a small LPR design with some very unique free form fins. I think I'm going to have to build it now.

    A T3 and stratologger fit snug in the PVC threaded coupler at the base of this 4" nose cone. Just need front stop blocks for the batteries, a switch for the altimeter, and zip ties to keep everything in place.

    No drilling delays on the Hot Bird.

    I accidentally spilled and wasted a bit of expensive resin despite trying not to in my Roc-A-Chute PNC. I'n going to try putting a vent hole in the tenon of today's print and see if it drains when it prints.

    I also made another aborted test print of an Aero-Pad leg. It had horrific layer shifting that oddly seems to be specific to this part. I'm going to try again with a lower bed speed today.

    Another update: the white, blue, and orange resin has been delivered. I will change out colors after the current print is done.

    The PNC with the vent hole retained less resin then the previous print. I'm going to see how well this works as I work up into reproducing Centuri PNC-8s and above.

    The Aero-Pad leg is only 33% into a print. It's still too early to tell if it's going to come out OK.

    No, it's not just you.

    What about printing it as a two piece? The cone and the base would each be printed with the closed side up and a gaping hole beneath.

    Anyway, on Sunday I changed out the power supply in my dead computer for a spare I found in the garage, and now it's alive. (It's Alive!) Good thing, 'cause if that didn't work there was basically no hope; it's so old that if it had been the motherboard I would have had to replace the processor, RAM, and video card along with, and I haven't the budget for that. Anyway, the first thing I did yesterday was a RockSim design for another funky concept. Still no internet at home, so I'll have to remember to put pics on a thumb drive and bring them here to work.
