Rotating Stands for Wings & Fuselage

[Sid]

Hi Everyone..
Am working towards starting a scratch build either a Patrol or LSA (haven't quite signed off on which yet) and in preparation am putting together some rotisserie stands for a pair of wings. I want to be able to use them for the fuse as well.
Can you guys give me some idea of heights and adjustability that may be required to the rotation point, clearing lower stand structure and the floor for both planes?
Appreciate the help.. it may not be the last time....lol

Sid, I wouldn't recommend a rotating wing stand for wing assembly. The two fixed 4x4 post method has the advantage that once you get the attachment points lined up and plumb, they stay that way. You would not get the same security with a rotating stand.

This is what I use for storage, not assembly. It requires attach angles on the outboard rib, I just used some leftover .050 from my fuel tank build.

Similar to Paul's. Center of gravity is adjustable.

Mark's rotisserie is a great design and took time to build. Mine isn't as adjustable but still useful. Bottom line is don't hesitate spending the time building a really, really nice unit. Just like using a well-made tool, it will save you many, many hours of frustration and will turn out a better product. Also it will save on potentially damaging any parts, especially the wings, by not having some rickety thing to fight every time you want to move something. I can't count the number of times while working on the fuselage that a turn of five or ten degrees and then having it stay put made a world of difference in access to a weld area. On the plus side when you are done with it you can sell it for good money as it will be useful for any light plane project.

Excellent info thanks... still looking for that height measurement and the amount of vertical adjustability that would cover both plane options... Ballpark from floor to pivot point?

Cheers...

Both Paul and my rotisserie are height adjustable. Paul uses square tubing...mine is round pipe with square tubing inside and a square guide. I have about three feet of vertical height adjustment at both ends. More at the firewall with the adjustable center for balance. Wait...have a pic that'll give an idea of how high it'll go.

Here's a pic of the fuselage covererd. Is balanced. Can unlock the index pin, turn the fuselage to any point on the compass and she'll stay. Will make it easier to see the light reflection for paint flow.
In this pic you can see where the center balance is....

Hi Sid

The rotisserie for my wings is very simple, see photos. Pivot point is 950mm from the floor. I haven't got to the fuselage as yet, i will either modify these stands or build a new one when the time comes.

[Sid]

Thanks guys.. around 900-1100mm looks about right... I will build that sort of adjustability in..

Today I watched a video that showed Rob Caldwell's rotisserie.

I think one thread dedicated to building a Rotisserie would be a service to our community. Today, a "Search" results at least five threads on bearhawk.com. So I will add some freshly discovered information then add links to the other threads I came across in order to ease future searches and consolidate things.

The above youtube link at 6:30 shows Rob Caldwell's rotisserie. He's modified HF engine stands that receive two universal joints. U-joints are typically $30-50. I'm kind of frugal. Today, the Surplus Center (surpluscenter.com) has a steering universal joint I will try. $10 each.

Here are some u-joints on eBay for $10 each. Mine were $15 each at the time.

Made mine out of wood and placed on casters. Painted two planes with it and when your done, take it apart and store it out of the way. Used it for the wings too. Just remove two bolts and drill two more where you need them. Shortened it up and used it for the ailerons and flaps.
