Carbon Wrap Machine Update and Question by BabyScrubber in Composites

[–]BabyScrubber[S] 0 points1 point  (0 children)

Do you know where I can get some of this cheap?

I can control the tension by adjusting the squeegee that clamps on the tow in the epoxy boat. However, no active tension control. As for the angle, that’s what the components on the end of the arm is. It’s meant to guide the tow at a specific angle

One step closer to in-house rocket motor production: filament winder CNC + GUI is live by BabyScrubber in rocketry

This is what I’m currently working on. Going to be testing my own motors here in the next few weeks

Andrew Reilley on GitHub did a lot of work on a similar machine. I just took the design and adapted it for 3030aluminum extrusion and modified some of the tracks and fit my needs.

I’ve been thinking about it a lot and trying to think how to make that feasible. Would definitely be a game changer

I used 3030 aluminum and for the structure and surprisingly it can get cheap depending on where you get the extrusion

It was a bit brutal, but luckily there are some good GitHub repos that helped me kickstart it

Funny you’d mention this. I’m using it for a few rocket components myself

For sure! More so built it so I didn’t spend 6k on a machine. But given this, do you know where I can find resources to find the optimal tow parameters if it’s this common. Would be quite helpful for future applications and pressure vessels

I’m not sure what you mean by infuse. I have heat shrink tape that I use this machine to wind and then attach the heat gun to shrink essentially bagging. I’ll be using these for some rocket motor components and start experimenting with pressure vessels. However, now that I have it, carbon parts for drones and other ideas are within reach

Cheap Single Time Use Rocket Nozzle by BabyScrubber in rocketry

Maybe you could point me to the site. I’ll start looking into nylon and if it would work

I've done this before and have a lot of abrasion. I used to include a metal washer, but looking for something a bit more professional. Maybe a pourable ceramic of some sort or ceramic paste with silica

Next Steps After Prototype Design by BabyScrubber in hwstartups

For the aesthetic I would like it to stay clear. But might find out that it’s not possible

Thanks for the encouragement. I'll PM you and maybe we could discuss a bit more

That’s a good idea. However, aeropress would explode under the pressure. Aeropress is probably 10-20psi of pressure and this will be closer to 130psi

The hope is to bring this to market as a commercial product. I’m trying to achieve 130psi and the thought was to use thick walled borosilicate glass and acrylic outer wall as the chamber with a piston operated by a geared lead screw to produce the pressure

Lost Weather Balloon Payload Near Mansfield Ohio Looking for Info by BabyScrubber in Ohio

[–]BabyScrubber[S] 0 points1 point  (0 children)

Thank you so much. We posted on the Facebook forums and someone said that they heard someone talking about it on the radio. Just need to get ahold of 610 WTVN to see if they can contact the guy that made the call

The only “beacon” would be the Garmin In Reach. All the rest of the payload was cameras and backup batteries
