Adjust-O-Jig

It seems that someone was looking for a wing jig not too long ago. So when I saw this on Ebay I thought I would post it. Do a search on item #5925568072. Seller rcchristian claims it is brand new never been used. His starting bid is $49.99 with shipping of $15.00. I do not know if that is too high or not. Later, DOC

I used an adjusto-jig nearly thirty years ago and built straight wings and fuses. Pulling it out two years ago when I got back into the hobby revealed problems. The plastic pedestals had warped over the years, creating a jumble of rib placement. Almost impossible to line up ribs 90 degrees to leading and trailing edges. I'd be cautious about purchasing any adjusto-jig these days, since they must be old and are liable to be warped. It would be useful for a manufacturer to bring the adjusto-jig back with pedastals made of metal or a more stable plastic. The aluminium under base is a great idea for providing a true and straight reference. I don't know of anything on the market today that provides a similarly simple and accurate jigging platform.

I was looking for one last year and Greg Bahrman was kind enough to volunteer to give me his. He grudgingly accepted an engine in trade for it. The jig is in great shape and in fact I used it to build the infamous Humongous wing. Wing came out straight.

I do think that I'll start using the Lincoln log method in the future. Got all the parts from Tom at Brodaks.

Spelling edits - geez!

If you go to the Lincoln Logs, are you interested in selling your adjust-o-jig?

The older I get, the better I used to fly!

I've got an adjust-o you (or whomever) can have. One pedestal is broke, but I will make a replacement wooden one if necessary.

Tools

I modified my A.J. to use arrowshafts instead of steel rods.
A fixture to make wing rib holes for the arrowshafts was made also.
Thia setup makes a more accurate wing jig ( in my mind )
Sorta like the Rabe set up.
Biggest problem i,ve had with the Jig is the center adjustments
changing , mostly from me leaning on it or putting too many weights
on the wood;
You may want to watch this.
All in all , it works very well.
I also have a .290 oval shaped glass plate for jigging the wing,
tail, and body together accuratly;Like Boeing and the Nextel and craftsman truck series people do.
This is the best way ;they won,t go second best.
I have never used the fuselage aligning fixture that comes with the adjusto jig. That is about to change:)

I had the same problem with trying to hold the jig straight using the factory adjustments. I would get some sag in the middle and thus some dihedral. I leveled both sides using a 48" long alum. rule and the drilled and pinned both sides using 1/8" dia music wire pins that I made. No problems setting up the jig after this mod.

Hi, Dick-

I got sag (and dihedral) in my Tom Morris wing building table too after using weights in a moist environment on my Lincoln-Log/New-Millenium wing. I'm not sure how such things can be entirely avoided. I didn't mind the dihedral from a flight dynamics standpoint though; it just complicated other measurements a bit.

'sorry to hear of your mishap out at the field last Sunday. I was thinking then of how fortunate I might have been not to have taken "one last flight" on the adjacent circle. WELL...the guys talked me into "one last flight" Tuesday night at dusk to check out a prop I didn't expect to work at a setting I would not have chosen. The thing cut out overhead and hit the ground before I could run far enough to regain control. There is now some serious structural damage to the red and gold "P-Force". I could really kick myself on this, as the plane seemed to fly extremely well, but never got the chance to serve it's purpose due to chronic fuel pick-up problems. Progress had been made - tank movement, Armour-All, etc. "Shucks"...

From my youth building on tables and hoping for the best, I thought an Adjust-o-jig was a great deal on eBay.

Built myself the best wings I've ever built for several airframes.

Then I decided to build a CSC Super Chief for my Tom Lay .60 as a basic stunt trainer.

Everything went well until I thought it would be a good idea to put a thin coat of PolyCrylic on the structure and ended up gluing all of the ribs to the jig.

I recovered, but Christ, do I feel like an idiot.

Jigs are wonderful.

Al Rabe's instructions, I think, are way better than the Adjust-O-jig.

I'll be placing mine on ebay along with the best prose I can manage and see what I can get for it.

Cy.

and cheaper.

ok what are Al Rabe's instructions ? thanks if there to long maybe you could email them to me

I wrote extensively about my jigs and wing building techniques in Stuka Stunt topic #6421. Maybe a more computer literate reader can help you obtain this information,

Adjust-O-Jigs are those items that CL club members typically give as Christmas presents in those grab bag end-of-the-year parties. They are sort of like fruit cakes too; those ones that have been given as presents, a single one passed from person to person for...decades.

thanks al this helps maybe now i can build straight wings you have any pics on fusealage jigs thanks again

I guess you can use the URL from Bob above substituting the topic numbers to read a series of construction information I did a year ago.

thanks al i appriciate the info and the time you put in them.

al your fuselage jig is it custom made for each plane you build or can you use the same jig on different planes?

The bases are simply pieces of 4" to 6" wide MDF or particle board. Each laser cut airplane comes with bulkhead pockets which form the fuselage jig. Basically, throw the jig away after each airplane. Very expendable. A 3/4" x 6' shelf of MDF from Home depot will make all the parts for two complete wing/fuselage jigs for about $10. It is also possible to clean off the pockets and wing vertical risers and reuse the bases, other side. I average less than $10 for each set of jigs and don't hesitate to start each airplane with fresh bases. Jig tubes costing about $25/set will last years and build as many airplanes as adjusto-jigs. Pays your money and takes your choice.

ok were do you get the jig tubes. thanks again for all the info

Look up metals in the yellow pages. I used a place called Metals Supermarket. Similar stores are available in any city of any size and can be mail ordered with significant shipping costs.
