      @jpourkav Yep, that was the next step, just didn't have enough time to implement. Though maybe now for a thesis...hum....

      Thanks.

      @david1513 Yep you're right, and those would have been the next steps. Thanks.

      @grumm70 This particular set up is much too small to be cut into smaller pieces...but the problem with doing that would be containing the exhaust pressure, if any were to find its way out of the nozzle other than in the intended exit, then that’s when it'd go kaboom. Though it'd fun to try.

      Rockets are always dangerous no matter what size they are, this fact isn't neglected at this school, in industry or anywhere that wants to get into rocket science. Safety planning is heavily looked into before anything is attempted like this at Cal Poly. But ease your concerns, this set up is not...

    @badboybilzer True, but I think the issue was more switching over from starting with propane to oxygen...there was probably some 'air' in the lines along with pressure differences. However, I did have this problem with other hybrid motors that I was working on at the school. Thanks.

      @KittyRokher Thanks...well I machined this myself using the school machine shop, so I only had to cost of the materials...but each nozzle took over 30 hours of machine time. A bell nozzle however should be a lot faster to make on the lathe, probably looking at around 4-10 hours depending on the s...

      @762gunr Hard to really tell the difference since the design of the nozzle changed...but it was fun to watch none the less.

    @earthstation1 that is steel....chrome-molly. The second nozzle is made from stainless steel. Which is a little better in terms of the melting temperature, but the redesign is what fixed the issue. If I had more time and money I'd have gone ceramics. Thanks.

      @sslayer0117 it all depends on what you want to do, you can buy kit rockets that'll range from $50 to thousands...or you can build from scrach, a lot more fun, but takes way longer and will probably cost more than a kit. But either way is a lot of fun.

      @kyle1058 Thanks, Cal Poly SLO is a great place to go to and be at. Lots of hands on projects, and you have the freedom to invest your time into whatever you wish with all the backing and support of the professors.

    Diesel Conversion Project -- Cummins 4BT into my 85 F150

    The truck started out as an 1985 F-150 5.0 EFI 4x4 AOD/NP208 with 3.27 axle gearing (I believe, been a while since I've checked.) with 31" tires. N...

      @paintballer653 Well, I pretty much replaced everything, the engine, transmission, transfercase...but unlike many others, I didn't have to modify the Cummins oil pan at all. It all fit as though it was meant to be in there. Those are the major things that were done, I've spent a lot of time runni...
