On TRF there was a debate where a post complained about the price of an Odd'l Rockets accessory.
I stayed out of the current conversation but finally had to add my two cents.
This post is not meant in any disrespect for anyone in this thread. But, I feel I should say something. For those who have used the Adeptor with good results, thank you!
I'm the guy that designed and produces the Odd'l Rocket Adeptors. I also write the modelrocketbuilding.blogspot.com blog.
I watch the prices of rocket kits and engines. If I see something I feel is unreasonable, I simply pass up the purchase. It's always your choice.
I sell kits and accessories to vendors at a wholesale cost. While I have a suggested retail price, the vendor sets a final price to make a profit.
The amount of time it takes to make an Adeptor is more than you'd think. I am very picky about quality and fit.
To produce this product, investments included a vise, drill press, metal drills, metal taps, tap handle and fine files Most kitchen table builders probably wouldn't have these tools at hand.
So far, this doesn't include the price of the Adeptor materials and my time. I didn't buy the parts at Home Depot, they don't carry what I require. Who knows? I may have missed them in the fastener aisle. I have bought the large washers at Home Depot.
To Ez2cDave, the product you showed from Lowe's is not what I use. It may have a hole in the side, but it isn't tapped for the thumb screw. That nut may not fit the bolt on a camera tripod.
You'd still need the vise, drills, tap and handle. If you have the tools, time and skills, have at it. But don't forget where you got the inspiration. I give full credit to that picture from the Enerjet News, January 1973.
I'm fortunate to produce (draw, typeset and print) my own instructions. If I had to pay an outside
graphic artist to draw up instructions the retail price might be a little higher.
Add to that, I usually have to pay postage to get the products to vendors.
There is more to small scale product production than the average hobby consumer realizes.
After you've sold a few thousand kits you understand and look differently at domestically produced, small vendor pricing. Where Estes may produce thousands of a single kit design, I produce 25 kits at one time.When you buy in bulk (thousands) and bag kits overseas your wholesale price will be much lower.
The first time I used the prototype Adeptor for a camera tripod launch it saved my sore knees and enhanced my rocketry experience. If I was not the producer, I'd buy one myself.

A port from YORF:
Here's a brief update. We've flown these a number of times now, drag racing fun; the last time at NARAM 60. I finally have the paint finished, decals placed and canopies installed. I don't have a pic of all four and one of them is still missing the nose cone.
Fun rockets with lots of potential. Some of the decals are kit decals, the rest are from Sirius Rocketry.
I'm still thinking about buying four more and kit-bashing F6Fs with a Blue Angels scheme.

The first time I tried to remove a friction fit engine from an Estes Beta, the tube was bent and the rocket unusable.
Now available from JonRocket.com:
BT-20H HEAVY WALL BODY TUBES!
To see the listing, CLICK HERE
On the left is a Estes BT-20, on the right the Odd'l BT-20H tube.
Standard Estes BT-20 style tubing is thin walled (.013") and prone to buckling and bends. Thin wall tubes can’t insulate against the heat of ejection charges. Paint above the engine mount area can blister.
This new tubing has the same wall thickness (.021") as a BT-55 or BT-60 tube.
The inside diameter is the same as a BT-20 tube. (.710")
Thicker wall tubing is less likely to shrink or “coke bottle” when a glue fillet dries.
Standard engine blocks (5/20 rings) will fit as an engine block.
Existing centering rings can be easily peeled or sanded to fit the slightly wider outside diameter.
- Engine mounts - Perfect for the new C and D Quest Q-Jet engines.
- Ejection Stuffer Tubes - Stronger when exposed to ejection charges. Longer life, more flights.
- Strap-On Boosters - Less damage on landing under streamer recovery.
- NAR Superroc Competition - Stronger tubes equal longer length designs.
- Sport Models - Stronger as a main air frame tube. More success for school, Scout, 4H and general sport rocket projects.
The yellow plastic nose cones from Apogee are a great fit for the thicker wall tubes. These nose cones have a wider shoulder than standard nose cones. To see them, CLICK HERE

On the right is the new BT-20H, heavy walled BT-20 tubing. It has the same wall thickness as a BT-55 or BT-60.
Imagine the applications - Stronger stuffer tubes, strap on boosters, Super-roc competitions and general sport flying with longer life models!
I have never been a fan of the BT-20 style tubing ever since I crimped the BT-20 on my Estes Beta trying to remove a friction fit engine.
This stronger tubing will better insulate a hot engine and won't shrink up when the white glue dries! A perfect fit with the Apogee plastic (Starlight) nose cones.
These Odd'l Rockets engine mounts have a 3" long SPRING STEEL engine hook. That extra 1/4" length hook allows you to glue the engine block in under the upper bend of the engine hook.
The REPLACEABLE KEVLAR mount ties the cord underneath the lower centering ring. Pull it out, check the condition of the line and replace if needed.
I was given a new Quest C12-6 Q-Jet engine for testing (Shown above). I went back to the hotel to get the products together and test the fit of the engine. The newer, slightly smaller diameter Q-Jets are a perfect fit with the labels on!
My third product unveil was a long time coming.
The Odd'l Rockets FIN TOOL will finally be sold after I return from NARAM. Many were interested in a demonstration after I was meeting participants at the front of the hall. These will probably show up on the Odd'l vendors websites in September.

I got an email from Gary S. asking for a measurement in the F-104 Starfighter instructions. On the first run of the kit instructions were missing a measurement.
In Step 20, the back end of the intake nose cone half is glued 5 5/16" from the back end of the main air frame tube. Step 20 is shown above.
I've sold quite a few of these kits and haven't heard from anybody about the omission. Sorry for any confusion! If your build is a little off, it shouldn't matter. I've seen F-104s fly at club launches with no stability problems.
