Sturdi-Built Lines

[Dan McEntee]

      Hello Group;
   Alright all you old timers in C/L scale and carrier!!! I just got some stuff out of an old friend's estate, and in the box was four sets of ready made Sturdi-Built lines. They are three line sets, made up with eyelets and small connectors. They are brand new in the box with paper work. The question I have is the size and lengths. They are .012", .015", .018", and .021". The weird thing is that they are all the same length, 67 feet, 4 inches.One line is obviously shorter that the other two and that is the throttle ,line, correct? I just can't think of how they came up with that length for all four sizes? How can something that was rated for the .012" lines fly on that length of line? If they are carrier lines, that seems too long to me for any measured distance by laps counted? Not sure what I'll use them four. but the boxes and paper work are cool! Thanks in advance for any information.
Type at you later,

Scale stuff, I reckon.  Steve

Anything that needs .012 would be small and be flown on 57 to 60 foot lines.

  Hi Fred;
   Yeah, That's what I mean. All four boxes are marked with the exact same length, 67'4", but are graduated in diameter. Even the .021" sounds kinda long, and they all have the same small line connectors that look like they are for 1/2A. All factory fresh and new in box. The guy that had them had a hobby shop for several years here in the area, and maybe they are left over from that, like a special order someone made and never picked up. The boxes and paper work inside are cool! If we get together at Buder soon, I'll bring them along.

I don't fly anything on 67 foot long lines, the longest I use are 60 feet long. The majority of my models even at 13 lbs are flown on 57 to 60 foot long lines.

You could easily separate the lines, then cut them to size. Not difficult.

Dan,
Actually measure the length of one set.  My guess, and I'd just about be willing to bet that they are actually 57 ft. 4 inches long and were intended for carrier.  Those diameters match up with the carrier rules of old.  The 67 may simply be a misprint...I've seen that in the past with Sturdibuilt stuff...garage operation.

The J. Roberts lines were made specifically for the J. Roberts model kits. The kits came with the lead outs pre-crimped to the included 3-line bell crank. These kits were mostly for carrier event so needed to be 60' from the center of the model to the center of the handle, so the lines needed to be 57'4" to compensate for half the wing span, for a total of 60'. 67'4" if you were flying Scale or sport and wanted 70'.
All three lines share the load and are of equal length.
The loop and crimp on these old lines is very small and will usually only fit the "dog bone" slide style line clip.

    Thanks for the replies. These have the small eyelet crimped on them but have the more current style connectors on both ends, and small ones at that on all four sets. I read the box a little more closely, and it says," Three lines of flexible stainless steel cable tied to exact even lengths. Ready to use to conform to 60 and 70 ft. distance from handle to model."  These must be made up for the 70 feet dimension. The address on the box is Route #4 So. Cloverdale Rd. Meridain, Idaho 83642.  This is just a curiosity , and I'll probably try to use them somewhere by redoing the eyelets. The cable is still nice and shiney, so with new wire wrapped ends, they should still be usable. Might keep the .021" set intact just to add to my collection of such stuff.
   Thanks again for the input. I just think it's fun to take a look at the old stuff.

As stated they are made for the old Sturdibuilt kits.   You could take up carrier or scale if you have the kits and the Roberts handle.   The new handle that Brodak sells may work if you use the Brodak bell crank system.
