I have read most of the threads here about building jigs and there are several different types and materials.
I am interested in this one from Scratch Builder Warehouse. Has anyone had experience with this item and any comments pro/con? The only disadvantage I can see is it isn't suitable for wing work.

Dick,
Those kind of jigs are pretty cool. It's not really very hard to make your own jigs, though when I machined the pieces of mine, it was certainly tedious. I'm looking a building a new wing and fuse jig (and possibly a separate stab and control surface jig) and I'm sure it will be just as tedious the as the last time. Sigh... But they sure work well.

Uh Randy, can I have first dibs on your old jig when you build your new one? %^@

Sure Mark. ;D

That jig was first described as a construction article in RC Modeler many years ago. It is OK but I find it awkward and be careful if you use CA and not glue parts to the jig.

I built one like it from some plans that are on line. It works well, just don't CA the airplane to the jig. ~^
I used mostly scrap 1/4 plywood for the uprights, and some MDF shelf board for the base. I had a lot of 3/8 carrage bolts so the uprights are thicker to support that.
I store it flat on some some shelf brackets just like another shelf. It can be a problem to store

I built one too from the plans. You do need to have the ply uprights dead square! Also great for Profile fuselages and making wing and tail alignments! No problem storing...It stands vertically in the garage taking up about 12 sq inches of footprint!

Do you remember where you found the site?

Have you considered the "Blue Sky Building Jig" from Blue Sky Models? It's pricey but looks to me like the best fuselage building jig out there. 8)

Yes, I did look at that. It is a work of art.

Why couldn't we buy a length of this...

Cut it into <>3 inch pieces, add a shelf board and hardware to bolt it together. 48 inch piece would give you 16 uprights (8 stations) and depending on what hardware you have laying around you could probably build it for well under $50.00.
The hard part would be making sure you cut the pieces square, a half way diecent band saw would work fine. A table or radial arm saw can also be used with the right blade.
Just a thought..

the one i built was like this one. I think is is a copy of the old RCM one I used a Table mounted belt sander to square up all the uprights

Dick,
The original R/C web site with my jig has been taken down, or moved. But the plan in Dave Siegler's post is for the same one. Works great. And the sanding trick to get the uprights dead vertical sounds like a winner to me. I had a furniture making bud cut a couple of sets for each of us!

More jigs
Ty...I noticed that the uprights have some sort of facing on them. Dark, maybe plastic sheet or wet/dry paper? Is this to help hold the parts in place, or keep them from being glued to the upright?
Regarding the arrowshafts...spliced, I assume, with what? Putting a plug inside would be easiest, but then you can't sight through the bore to check alignment. Putting a sleeve on the outside would work, if it was a good, tight push fit. Maybe a block of plastic? ??? Steve

Steve,
I dont know about Ty, but I just build my wings in two halves , ala Pat Johnstons method. and then join them into one peice. Sheet the mid center section after its joined, it aint going no where.
that way you dont need a super long jig, or have any need to splice the arrow shafts.
Actually come to think of it, on my Avenger, the wing construction would not allow a two piece wing, so I had my jig table setup full length, then I built one half of the wing, slid the tubes through the ribs part way, built up the centersection, slid the tubes some more, and built the other part. Actually worked pretty slick
