Default Bomar Alpha-B

This one is REALLY rare! As far as I can find, there are no instructions available for any of the Bomar kits online. Only catalog on Ninfinger is from 1969.

Here are the instructions and parts photos.

Body tube is same as Centuri ST-7.

Enjoy!

LOL, I know. I love that silly ruler. Definitely 60's but not too rare. Cheap enough on Ebay. Just do a search for "astronaut ruler."

Step 1 "Emplacing" the engine block.
I looked it up. Emplacing: verb, to put in place or position.
Step 2 "Securing" the engine block.
I had to read step 2 twice, never saw instructions that had you apply more glue to the bottom of the engine block.

The streamer looks like old, heavier picnic table cover material.

I played guess-your-best using an old catalog scan a couple of years back and built this one. It made it two flights before becoming an ornament in the B6-4 Field Collection. https://www.rocketreviews.com/alpha...-1969-1971.html

Thanks for posting this, Steve. I'm obviously ready to try my hand at another Alpha-B, maybe an upscale now that I have real fin patterns. I also have the parts to make a cheap and dirty copy of the Alpha-1.

Chris,

It's no wonder we're friends, LOL. I loved the use of the word "emplacing" as well. I think you are supposed to lift your pinkie finger on the hand doing the emplacing while accomplishing the task. Very fancy rocket building.

And you are right, the streamer has a slightly rough texture, could be picnic table cover.

I also really like the pattern included in the instructions for a "streamer/parachute protector." It says you can cut these out of flameproofed crepe paper and use them instead of wadding. The protector pattern is the same as what came in the first Model Missiles kits before wadding, as we know it, was invented. The shock cord attachment method is also similar to the Model Missiles kits using a slit in the side of the tube. But the Bo-Mar instructions suggest you insert it in the reverse direction, so the free end is at the top. Not sure that was a good suggestion. But clearly this model owes a lot to the original Model Missiles kits.
