What did you do rocket wise today?

Awesome, gonna be nice.

Are you going to paint it like the real one was? It is a great addition to your fleet. Estes is also in the making of Retro kits from years ago. I would like to see some up scale kits.

 

[o1d_dude]

Ordered some rail buttons from Rail-buttons.com for various builds.

Ordered a LOC Blaster and a length of 38mm airframe from LOC

Swapped emails with Teddy from One Bad Hawk concerning a harness order.

What are you planning to do, may I so nosely ask?

Radio controlled BGs and RGs.

Ok kinda thought so, but you guys are always coming up with something out of the normal

Right, and strapping a glider to a rocket so you can steer it down is totally normal.

Amidst various September 11th posts on my feed, facebook reminded me that I got my L1 4 years ago on the 10th.

watched disc 2 of Midwest Power 13 from 2015 by Justin Farrand, thanks

Well now..... seems this followed me home... I can see Balsa on it in the near? Future
Funny how the picture shows the years old mess from a previous similar Lathe!
Now I have totally forgotten how to turn anything ... lol

Start with basswood. It's much easier to turn and learn on than balsa. Cheaper too. I added the bed extention to my Jet when I got it. Only really needed once tho. Get a nice 4jaw scroll chuck with adjustable jaws.

 

[XrayLizard]

Agree on practice. Actually I have turned hundreds of game calls in the past... it’s been over 10 yers though . Feel like I have forgotten everything!
I can’t even recall my favorite turning tool types I used ! Pretty sure it was round nosed though. Today I just got a 1/2” gouge. Gotta think clear about the tools , since they are not cheap.

 

[Joshua F Thomas]

Ordered some kits from ASP. WAC Corp with Tiny Tim, Super Loki Dart, Black Brant VB and a 3 pack of 13mm kits (Sandhawk, D-Region and IQSY Tomahawks)

ASP kits are very nice, I really like how well Andy has made the instructions. They're easy to follow and have useful diagrams and suggestions. The part quality is also high.

watched "Thunder Struck 5 " rocket launch dvds tonight, filmed in Indiana

Don't forget you can use an angle grinder on the toolrest instaed of a chisel. I have also used a Dremel in the same situation. It makes essentially a toolpost grinder and can give you a better surface finish on balsa and other material.

Got my Beta in the mail today. That was very fun. But the big thing was getting my modified Estes base finished up for my restored Gemini Titan. Here's the pic.

 

[kuririn]

Added one more to my Centuri Stellar line: The Semroc Stellar Lancer retro repro.
Built a Stellar Hercules clone and a Stellar Photon Probe (kit) earlier.
3 down, 3 more to go.

 

[tOD]

Launch today with Tripoli Pittsburgh. Weather looks good.

 

[JohnCoker]

Well, with all the smoke I've been sheltering at home with air filters running, so nothing in the shop. But I've been doing a lot of work on the new ThrustCurve.org site, which is definitely rocketry-related.

ThrustCurve is a great site. Can't wait to see the updated version.

My poor wife (again).

We went to the park just before sunset, actually cutting it a little close - it was nearly too dark to see by the time we left. Wife wanted to launch the Estes Savage she had finished building (first stage only!) and I wanted to launch the Tall Boy in the smallest configuration to validate it was sound before going for the full 10 ft size.

Launched off a 13mm "wind test" bird on an A3-4T and it flew great, no wind worth speaking about. Wife then flew the Savage on a B6-4, and it had a beautiful flight - it almost hit me on the way down!



She wanted to do a second launch on a C6-5. On this launch, it took a 20-30 degree hook just after the launch rod. Flew toward the edge of the field, deployed... and came down right on the inside edge of the trees. The growing darkness allowed me to see that the motor 'popped' again at about 10 ft off the ground, so I'm fairly certain it is in the trees at that height. It was too dark to find it, so we're going to have to go back tomorrow. The wife is 0 for 2 on coming back home with a rocket from launches. At least I can point to the one I have still stuck in the trees at the same field and remind her of the high-risk hi-reward nature of the sport.

The Tall Boy small-configuration flew fine on a C6-5 in a 18-to-24mm adaptor. Looking forward to trying it in full 10 ft mode on an E20-4T.

The atria sit above the ventricles. SVT is (or at least can be) paroxysmal in nature. So is it just me or do SVT and PAT sound like the same thing?

Not quite. Tachycardia is rapid and coordinated contraction of the fibres. Fibrillation is an uncoordinated contraction of the fibres, the classic 'bag of worms'. Fibrillation won't produce an effective pumping action.

It's an old exchange, but it just hit me out of the blue that that was not the right answer. Sure, I know that fibrilation is a whole different thing than tachycardia, but I was comparing SVT and PAT, not AFIB. (And yes, I'm sure there's a difference of some sort.)

I shopped for nails. But it's mostly for looks, and a little for moving the CG forward. Shopping for a specific head size is harder than shopping for a specific length. Yeah metal, but I'm not quite sure where to find plastic that looks like metal nail heads. Plus I don't see how a few metal nail heads around a nose cone are any worse than a chunk of lead or BB's inside. I dunno.

Hmm... maybe I could slice wooden dowels instead. Not bad. I just thought of that. We'll see. No hurry.

Sorry, my bad.

This article says PAT and SVT are the same thing.

Cardiac was never really my specialty... Only remember what I learned as a student.

 

[Hobie1dog]

had to swap around monitors in the garage so that I could watch the assembly videos for the apogee level 2 rocket ,and I took it out of the package finally. I laid out the first set of components so maybe I can drill a hole tomorrow which will be step 1

 

[o1d_dude]

Due to fire-related Air Quality alerts I was unable to work in the garage on my rickets so I contented myself with irdering more motors and parts, tracking shipments, and running sims on Thrustcurve.org.

Locally the Air Quality Index has finally dropped down from “Hazardous” to merely “Unhealthy for all groups”.

I’m hoping for an improvement tomorrow to “Unhealthy for sensitive groups”.

Pandemic update from Cali: No child 17 years old and under has died from the virus according to State Health. 75% of all deaths were in people 65 and older. This means 25% of deaths were in people 18-64. 14K deaths in total for Cali with Los Angeles accounting for the majority. Hispanics accounted for 45% of deaths while Asians were below 10%.

Weird.

 

[GalantVR41062]

Getting ready for the launch tomorrow.

Lowtech 4: BT55 tube, 29mm mmt, small payload bay with GPS, RRC2+, apogee charge and chute tender (ematch, BP and rubber band). Going up on a CTI H53 with ejection charge removed.



This will be my attempt for the local H altitude record, pending flying conditions at the field.

I also performed a static fire of a research sugar motor in a AT 24/40 case.

ThrustCurve is a great site. Can't wait to see the updated version.

It's live now. (I had to push the new version on August 29 because the ISP hosting the old site died suddenly.)

I will check it out. Thanks John.

Got my TRA level 1 certification yesterday with Jim Jarvis as my TRA TAP. How prestigious is that! In fact, most prestigious rocket motor guru Stu Barrett was at launch pad helipng me out confirm continuity on my heavy short rocket. Thank you all! A cliffhanger flight none the less!!

 

[Joshua F Thomas]

Went back to the field to see if we could locate the wife's Estes Savage in the trees. Unfortunately no. Spent a solid half hour walking around in the treeline looking for it. The trees are thin and tall, meaning I'm sure it got closer to the ground based on what I observed - but it's just too hard to find it among all the leaves right now. May have to wait for fall.

Wife is sad. Not sure she'll build another rocket :/

Meanwhile my ASP 'Way Too High' still sits in it's own tree, mocking me; the streamer is very visible.

Thanks for the website info.
I wasn't aware of rail-buttons.com
