Hi Robert,<br />
I like so many other guys built my brake into my work table. It works like a conventional brake in that it has center rotation and 2 hinge pins that the bending leaf rotates around. This is a little unusual for a home built brake that is 8ft long. Most guys use piano hinges or multiple hinges to accomplish the rigidity needed for the brake and sacrifice center rotation. This is obviously not a problem, I just wanted to see if I could make it operate like a conventional brake. The…
Hi Robert,<br />
I like so many other guys built my brake into my work table. It works like a conventional brake in that it has center rotation and 2 hinge pins that the bending leaf rotates around. This is a little unusual for a home built brake that is 8ft long. Most guys use piano hinges or multiple hinges to accomplish the rigidity needed for the brake and sacrifice center rotation. This is obviously not a problem, I just wanted to see if I could make it operate like a conventional brake. The upper leaf (pinching leaf) is located to give a 1/8" radius and is spring loaded so that in normal position material can be inserted. I am very satisfied with the brake, it produces a very straight part and I can make bends over 90. However, If I were to build it again, I would make it free standing and make it out of all steel. Incorporating it into the work table was much harder than expected, I have allot of steel bracing under the table to prevent flexing.<br />

Hello Scott,<br />
So far the longest bend I have had to make is the rear spar in the main wing. Unlike the 701 It is a one piece spar, but because of the length, it is built in two parts, and joined together near the area where the rear strut attaches to the wing. My I ask who brake did you build, was it Mac's <a href="http://www.macsmachine.com/">http://www.macsmachine.com/</a>, or Dave's…

<br />
I also built a brake from plans , <a href="http://www.ch601.org/tools/brake_plans.htm">http://www.ch601.org/tools/brake_plans.htm</a>, but ended up purchasing a professionel brake from " Brown & Borg.<br />
<br />
As for your choice in aircraft, you would be far better served with the 750, rather then the 701. Everything connected to the 750 aircraft , is a big improvement over the 701.<br />

If there is anything else I can help you with, please get in touch with me at my personal e-mail address at the following. robert.pelland@cgocable.ca<br />

Good luck with your build<br />

Hi Robert,<br />
I like you purchased the 701 plans before the 750 came out. I am considering buying the 750 plans and building it because my engine choice is a corvair, which will work in a 701 but it is marginal. One question; what is the longest bend in a 750? I just completed an 8 ft brake and would love to think that I wouldn't have to rebuild it.<br />
<br />
Thanks,<br />
