Bend angle for tail wire link

[haribole]

Dwg #21 gives details of the tail wire link to full scale, but not sure how much to bend and how to go about bending this accurately?

Thanks Wayne for explaining this, wanted to bring this to the forum for posterity.

Thanks
Hari

The drawing also mentions to make 6 of these, but should I not be making 8? 4 wires , 2 ends each.

ooops! Just saw that the fuselage has last two

Bob put some more detail in a short write up in 2007, 2Q Beartracks. He described his method for making the tail wires. In that article he list the bend angles as 18 deg, 29 deg, and 59 deg.

I went a while trying to build with Bob's Bearhawk book and current Beartracks. I finally subscribed to Jared's Bearhawk Tips, the whole thing. There are a lot of little details and answers that would have helped me fabricate the part just one time. Strongly suggest Jared's Bearhawk Tips to get all the Beartracks in a handy database that you can search. I was slower without that information.

Happy bending!

I didn't have Bob's Bearhawk book when I made mine so to determine the angle I ran a string between the two points then used an angle finder to measure the angle. Then I made an angle out of scrap aluminum (you could do the same using card paper) and use it as a template for the actual bend angle in the brake.

BTW: Here's what I relayed to Hari explaining how I made the tabs:

I just cut a approximately 12" long by 3/4" wide strip from 1/8" 4130 steel sheet and marked the pieces. Then I drilled all the holes. Then I made the bend for the first piece using my HF 3' metal bending brake. Then I cut it out on the band saw and rounded the ends using my bench grinder. It works best to bend one at a time using the length of the strip as leverage and keeping it squared up in the brake. Then I did the same for the next piece until I had all 6 made.
