What did you do rocket wise today?

Redstone is almost ready for paint.

My new engine. Without fuel 2 pounds. Mass of fuel 1 pound . Fuel - potassium nitrate and sugar. Full impulse 500 n.s.I may not know English but I can construct rocket engines

A pseudo clone that I had parts from Semroc just waiting. I did make the motor mount support an E engine

Beee-utiful!

We flew our upscale Dragonfly for the second time today. It went up on an L850W and reached 1820'. It was a beautiful flight with a nice gentle descent under a 16' Rocketman 'chute.



A local news station sent out a reporter to cover the launch, which was awesome.

Wow That is seriously gorgeous!

Got the base for my bandsaw disassembled and made a list of all the hardware that needs replaced and whatnot.
I'm going to paint it nice and all, and replace a few things, but the actual machine itself runs nice, and aside from new tires will just need paint.
She's going to look sweet all cleaned up proper.
It's also much easier to move around in it's component pieces.
I'm about to start the motor rewiring this morning as a matter of fact, and it would be good to go too but the insulation on the cord is worn out and cracked. I just did one of these motors a little while back, so no big deal replacing a cord and making sure the cardboard parts inside are intact.
Someday a variable speed motor and controller will be found for it.
I also would like to find an original cast iron base for it, and actually know a few places locally that may have that kind of thing.
Shipping would be a prohibitive factor for something like that, so though they are available online, I'de prefer to go to the places I know first where I go to ogle old cast iron woodworking/metalworking equipment, and inquire there first.

United body of the rocket with engine. I don't read how it is done in the instructions because there are none

I mounted fins.

Yesterday I finally got my Red flight on the Punisher in. It was lovely. Then I hit up the vendor trailer and loaded up on more motors, lots of recovery gear for my L2 project, and a FlisKits itty bitty Mercury Redstone that I couldn't go home without. Oh, and the Punisher won the informal "Best Looking" contest at the launch so a new Big Daddy kit came home with me! Yeah! Thanks OROC for a fun, if "slightly damp", weekend.

I opened the "Mega Der Red Max" that I ordered off Amazon and had delivered to work, to have a look at the components and instructions - pretty straight forward. But I noticed the about the top 1/4" of the BT was rolled in on itself . The nose cone was inserted into the rear end, so I pulled it out and stuck it nose first into the top end, hoping it will help straighten the damaged portion of BT. I won't be able to do anymore to it until I return home from work on Thursday. Not really sure how to address it going forward .

If it's really just 1/4", why not just cut off the bad part? You sure won't notice 1/4" (or a bit more, to cut it off cleanly) on that rocket.

reverse engineered my wife's smart phone

new lcd/screen and frame is due in Tuesday + replacing battery while apart

And I have considered just that, if some type of repair isn't feasible. :wink:

Try to slide some wax paper between the nose cone and the damaged area of the tube while inserting the NC in. If you can fit it, then apply some thin CA to the tube in the damaged area. Be careful not to soak too much in so it doesn't go past where the wax paper is. The wax paper will keep the NC from sticking. Then the NC will be supporting the tube while the CA stiffens it

And if that doesn't work then cut off the damaged part........

That sounds feasible.

Strengthening the fins to withstand the speed of light. One mistake and antimatter will explode

Went to the Woosh launch at Bong Rec area. Flew my repaired Wildman Extreme on an AT K805 Mojave Green to about 4100' with perfect recovery. This was to test repairs after MWP last fall- my L3 cert failed when the CTI M1830 ate itself due to a failed liner. All good so back to MWP for L3 cert try two.

Glad it all worked out, Mark. Are you planning next weekend at the Bong? If so, see you there.

Take it easy dude, You'll take that damned certificate. Look at me, what happened to me last time.
3 seconds ground fell by car.Ignition cables stopped nozzle.

Jason, I am planning on it. Not sure on both days though.

Finished external epoxy fillets on my Scorpion. I also made a couple launches (just 2) at the MARS launch in Geneseo.

Got me a Paasche H Series airbrush in the mail.!
Now I need to get me some pigment and try it out.
And some air.

Went thru me old airbrush pigments. Nothing I dare put thru me Paasche H.
So, I ordered some new Createx pigments and while on the site.Chicago Airbrush https://www.chicagoairbrushsupply.com/pahsesiacai.html
I went and ordered some other things.
Got me some cool stencils, different types of mask films, extra O rings for the nozzles and a Mona Lisa Gold Leafing Kit.

Got a new power cord with ground installed in the bandsaw motor, then got right on it with the drill press and had that up and running by the end of the day.
Rocketry will be easier with some decent shop tools at my service.
I've been saying I', going to get my drill press running again "Soon" for a long time now, but today was the day.
For some reason I had thought that the press had yet another one of these Craftsman 1/2 HP motors on it, but when I dragged it out, I was surprised to see this:

:confused2:


Anyhow, I had the motor for the bandsaw wired up with a ground now, so I grabbed the other Craftsman and began the swap from the 1/3hp Delta Milwaukee to the 1/2hp Craftsman. In reading the sides of the bandsaw motor and the new motor for the press, I was surprised to see that they are variants of the same basic motor, but I'm not very electrically competent or knowledgeable, so I just took the press apart in a minimal fashion to get the new motor and belt on and scrubbed it down good then rubbed MILITEC-1 all over everything, as I've used this oil for years on everything with great results.
I am making a knife sharpening jig, and even used it as cutting oil for the four holes I needed as it works well in my opinion as a cutting oil for short jobs.
Anyway,...



The press pully was at one time keyed, and not only was the key gone, bit it was obviously indexed wrong, so I made a new key from a piece of aluminum to fit, and I'm not going to put much of a load on it anyway, then fitted the pulley to the new motor, and the motor to the press.

I'll need to get a variable pulley for the bandsaw now too, maybe not need, but it would be nice to have for if I want to cut at a certain speed for a certain material.

Started working on the Binder Design Thug I got during this past Secret Santa. Cut off the nose cone base and have my son laser cutting some 1/4" plywood bulk heads for a nose cone avbay. Cut the fin slots in the body tube and placed the recovery harness eye hook on the forward CR and ordered an Aeropack 38L motor retainer from CSRocketry. Sure am glad most kits come with pre-slotted body tubes nowadays.

It seems as if it sat 20 years in a Vietnamese jungle Just kidding. I have only drill and angle grinder.

Yeah I know, but both of those motors were given to me, one by my Grandpa and one more recently with the bandsaw it goes to by a member here, who also gave me a small 1/3 hp motor that I'm going to fit to my lathe so I can have my bench grinder back.
My house is in full "Do It Myself" repair mode, so the larger machines are getting tuned right up.
I have two couches in my livingroom/work area, and since no one but the cats ever sits on them, I'm getting them out of here so I can just turn the entire space into my workshop.
House repairs won't be done til' spring, so may as well have a nice shop in the meanwhile.

Painted fins yellow . Why the hell not bought red paint? The Reds are much better but these are good for easy finding a rocket.

I'd like one small lathe.It would solve all my problems in rocketry. Now a straight hole can not drill

Special technology reinforced the connection between the engine and the pipe. Furthermore, 2 times painted the fins. As you know unpainted rocket flying 300 k is much worse than perfectly painted flying at 300 feet
