Default Main landing legs: Recommendations

The main shaft of the landing legs on the first two 44" studio models were brass with an aluminium sleeve over them. This looked great for the first few days but the other brass components started to scratch and score the surface. I've used solid silver steel rod as an alternative but although it looks great, this can start to rust if left in a damp enviroment. The best thing I've discovered is stainless steel. K&S in the US offer 5/16th diameter thick walled stainless steel tube. It makes a good substitute for the original aluminium, stays bright silver in appearance and being harder, doesn't score or scratch so readily.

Thanx, I wasn't aware that K&S even had stainless tube.

I've been looking into differant avenue's for a ready made set, but it
doesn't look like those will work out. So its plan B time.
We've got a pretty decent waterjet machine shop here.
I don't really know much about it, but CNC milling with water sounds
kinda Koowel :wink:

Hope you don't mind, I do have a Bazillion questions.
Where can I find springs?
How long should the main shaft be?
How long should the alignment slot be for proper 'at rest' and 'flight'?

I'm sure I'll think up more when I get to the gear.

Sorry Shrugger. Suddenly remembered I hadn't answered your pm yet. Unfortunately the remaining spare set of landing legs I had were bought a few months ago by a fellow enthusiast.

As for the length of the main shaft, it depends how long the outer tube is and the length of spring you're using but the slot that controls the travel allows roughly 28mm of movement.

The "in flight" position leaves 44.5 mm of silver shaft showing i.e. measured from the ankle where the aluminium outer sleeve meets the hexagonal ankle joint, to the bottom surface of the upper brass sleeve on the underside of the upper brass plate (did that make sense?).

I use springs that come out of the RS Components (UK company - not Radio Shack) box of assorted springs which appears to be where the originals got theirs from but other sources would do.

I think I got it. Looks like the operative bit would be "roughly 28mm
of travel"
I should be able to figure the rest

That's the total travel. At rest the legs only compress so far because of the weight but obviously there's a bit in reserve.

Ok, my LHS actually had one 12" length of stainless tube. I can't
really convey to you my suprise at finding it. Its probly been sitting in the
corner for years though, from the condition it's in. So the question now is,
how would I go about polishing it up

If it's stainless, it shouldn't need it. Is there any rust on it? Ordinary metal polish or car polishing compound should do it. Anything more encrusted will need something more abrasive.

No not rusted inside or out but it does look odd. Almost looks like its
Galvinized. Probly just from sitting and being rubbed against other
tubes and whatnot for who knows how long has dulled it to that finish.
Looks much better under the K&S sticker though

I'd try just a regular metal polish.

I've been working on the stainless tube. I started with 1000 grit to knock
off the grim and age Then went to 0000 steel wool. I'll need to work with it
a bit more with cloth and Brasso® but so far its looking primo.
Its got so many dings and deep scratches. I see now why it looked almost like it was galvinized.
I feel however, that an Eagle should look just the tiniest bit, beat up

Ya know, I had the answer in my Dremel box all along. I didn't even think
of it till a friend of mine pointed it out to me. Now I know what that
little jar of red stuff is for.
I thought it looked pretty good when I could see my thumb reflected.
Well, now I can see my thumb prints reflected!!! Looks like its been triple chromed.
Oh Yeh! The Big Bird is gettin some Bling
