JIG'S

[Bryan Higgins]

Hello Pilots

I finally had time to get my jig's finished and here they are.
They are all made with CLC parts. (Control Line Central)
Jim Snelson does a fantastic job making these jig parts.

The oak board you see is for the Fuselage Jig.  And the
White board you see is for the Wing Jig.  All i did was make
the two boards and mount Jim's Alumimum Angles  with
bolts & nuts on them.  Now i can build my planes perfectly
strait.  And they kind of give you a helping hand by holding
your balsa parts for you.  Thanks Jim
You can order these nifty jig sets from the site store listings.

Man, that looks familiar.

Hi Randy

I just had to make one like yours.  Im not the copying type but your design just
seemed to be the right one.  Now if i can build a wing that looks as good as yours
that works in the air.  Thanks Bryan

If you could search back to the early days of this forum where someone was going to have the peices done by a machinist.  But, he found out how much machinists charge.  I am glad that Jim took up the challenge and made the kits.  Using triangle stock, I modified my peices so I can have the typicle leading edge peices held in place.  It did make me go get a four foot metal level that is a straight as I can build to set up my set.  Don't forget the build pictures.

I made my first one about 10 years ago (possibly more). It was made from 1/8" plywood. Later, I got some aluminum angle stock and cut and machined pieces. I have some steel angle stock that has previously been machined at 90 degrees. I plan to cut that up into upright pieces and machine the pieces for a new jig. I think the steel will be more stable than the aluminium. I have to check the squareness of the aluminium every time I put it together.

Fun stuff.

I have aluminum angles that are 1/4" by 4" legs for my jig table.  It took a great deal of effort to true up the angles on the stock.  The 90 degree angle was close to 85.  I'm looking at making a fuse jig seperate from the table as i have to build the fuse in the center of a 4' by 6' building table.  It's not hard, just that a cool new jig would be a nice addition and make for easier adjustments for different airplanes.  The table is set for one fuse style and one size airplane. 

So, my question is what's the base plate of the jig made of?  just MDF or just plywood wouldn't stay true, there must be something underneath that keeps it true.

Hello Bruce
It sounds like you have a really nice building table.  Today it is very hard to find
true leveled stock or lumber.  Even todays hardwoods are not very straight.

So i did what a few of the guy's on this site did and used a Shelving Material
from Home Depot.  It's cheap and it's super level in both directions.  I do not
know what it is called other than White Laminated Shelving , there are many
different lengths and widths for sale. 

I belive i used a 22"wide x 96"long for my Wing Jig then cut it down to 60"long.

The Fuselage Jig is Red Oak 15"wide x 48"long and i picked thru the whole lot
just to find the straightest one.  I got lucky and found one that set flat.
I hope this helps Bruce talk to you later.  Happy flying

FWIW: One of the nice things about the Control Line Specialties jig is that it does not need a trued base...although it couldn't hurt. Each station can be adjusted both fore and aft and vertically which compensates for any slight deviations from a less than perfectly flat base. The wing is built suspended, so the base functions only as a support for the stations. As long as the adjustable vertical supports are level, the wing will be straight. 

My base is a 15" x 60" pine board. I looked at the shelving material but the pine is lighter. When I relocate the stations to set up for a new project the pine is easier to screw into than composite material although probably not as true.  See the first two sentences of this post.

Yea, the stuff I used is like Brian's piece. Mine is a 24" x 75" Formica 3/4" laminate. Generally used in cabinet shelving. Dead flat and easy to level. I got mine at Lowe's Home Center for about $40.

I used a jig and router to cut the slots, though I want to come up with a different system for attaching the uprights. Probably a carriage bolt and wing or knurled nut.
