(15) Landing Gear ( Mike )

Hey Guys,
I forgot to log this .... I'll try to go over things... But some measurements aren't going to be available....

If you need a measurement , write me and I'll measure mine...
.
.
OK The "Board".... Take care of "the Board" because you'll need it over and over....

This board is the same one you should have used putting the mount bushings on front of your fuselage....

You might wanna draw your lines on it.... and include the Datum center....

Here's how I started.... The board was set-up and leveled...
.
The lower tube was "Lowered" from stock.... I don't remember why... But I think the print measurements

weren't working , I have old prints... Newer prints might have been revised...
.
Also , I made my Bushings a pinch long , I'll trim them to size later ...
.
..
Gotta Fly...

OK,
Next , I positioned the lower 2X4.... it has a "Bow" in it... No problem , I snapped a straight line on it....

The 2X4 is "back" and "down" per print...

The print angles of this are misleading ( the drawing )

My "board" needed clearance for the legs to clear... This also gave a little support...

The axles are set up per print... a 1/16" welding rod under each end , gives the proper "Toe-in"

and measuring from the straight line , 5/8" is measured at the heel of the axle...

( This 5/8" measurement looks GOOD after the engine and wings are loading the gear.. )

The Axle "Sockets were welded ahead of time , and drilled for the gear leg...

next, more picture views....
.
One note , I took my time grinding the lower tube for a good fit side to side and clear the gear socket...
.
. Also ,
This is a flimsy set-up.... if you ever bump it.... You need to re check everything...

But it saves building some crazy Jig....

Next,
You can see the lower tube has been ground to fit way down , under the socket....

Before cross tubes are put in... Square must be double checked.... the cross tube will "Lock" things in place ...

Hey Guys,
I put the gear "on" the fuselage before welding... ( see Pictures )

Two reasons... First , make sure it's right before you weld it...

and second , I wanted to weld as much of it as I could , while it was being held....

This would help with controlling Warping....

OK, it's gonna be a little hard to put on.... The Fuselage area has already been welded , and has "Shrunk"

After you weld the Landing gear mount , it will shrink , and fit perfect....

Anywho,
I weld everything I can while it's bolted to the fuselage...

Then take it off and finish welding , Keeping "balance" of welds in mind.....

Which you should know by now....

If not , I can explain it to you...

PS Have some bolts that you can hammer on....and you could also "point" them a little.... ( Or round them )

it may be a little late to ask the question, but I can not find a measurement for the angle of drop from your board laid flat, to the plane of the axles, the angle of the mount to upper mount should resolve if I set the 5/8 inch on the gear, but how far down should the axles be compared to the landing gear. I have finally been cleared for physical therapy after the last back surgery and have already torn out a titanium rod, I don't have pictures but have been finish welding the rest of the fuselage, If I can get the landing gear done I might even be able to sand blast and primer my fuselage this fall.

If you check the print...page 2... I see a measurement of 9-3/4 inch...

BUT.... that is center of the axle... So add half the axle thickness...

Thank You, I missed that, I kept looking for it on the landing gear mount drawing.
