Folks,
I am looking for photos of unique rail guides and bottons.
If you have one, post it.

Original was more fun.Folks,

yeah, but not family friendly.Original was more fun.
I'm pretty sure a handful of members read the typo and laugh like Beavis and B**thead - "heh, heh, he said . . . "yeah, but not family friendly.
I am just looking for ideas to design my own rail guides. I am looking to others for inspiration.Coming back to the original question, there WAS a post talking about adapting a bird with launch lugs to operate on a mini-rail a few years back.
Not sure if it was ever done, but seems like with the right size dowel (one that would fit a 3/16 lug) you could mount mini rail buttons on each end, one permanent, one removable. Would enable someone to fly either off a rod or a rail.
Those are decent. I like them also.I prefer these from GLR or OBH when I can get them.

This is almost exactly the same as used by the front lug of the Astrobee D.Sir:
Attached are images of the fly-away guides I use for my six inch motors (nine inch are similar but longer).
These use a 7075-T6 “split-tee” rail guide and 1095 spring steel to wrap around the rocket. As you can see in the last image, hose clamps are rivited to the steel to allow the rocket to be clamped to the rail.
Guides are hard anodized to assure they slip on the 6061-T6 rails. This version falls away before 100 feet altitude as the spring steel opens up; I’ll be adding springs to the back of the assembly to assist with pulling the “split-tee” open as soon as it clears the launch rail.

I will have to think on that but I do not think that would be hard. The problem is getting it to stop at the surface.I'd like to see retractable rail guides. I've got an idea how to do it. The cool factor might outweigh the weight penalty.. Pun intended.
Easy. It's in my head now. But..... I'm drinking beer. Lets see if it's there tomorrow.I will have to think on that but I do not think that would be hard. The problem is getting it to stop at the surface.
I think you are rightOne more beer should make it much more clear and six........Easy. It's in my head now. But..... I'm drinking beer. Lets see if it's there tomorrow.
Find an envelope real quick and scribble it down! If you can't find one... peel the beer mat in two and scribble on clean inside.Easy. It's in my head now. But..... I'm drinking beer. Lets see if it's there tomorrow.
Very similar to my thoughts, but minus the beer. I gotta go to work.Beer glass for scale. View attachment 642568
I've had more beer and eliminated the external spring.Very similar to my thoughts, but minus the beer. I gotta go to work.
A servo allows you to release once clear of rails at a cost of 9g per servo. There's lots of flight controllers that have a programmable servo out.You would think you could eliminate the servo and just use a spring. You would need a "pull tool" to pull the button out to engage the rail and the spring would do the rest when then rocket clears the rail.
I am going to post a few this week.
