    Viking,

    So, how much did you measure for the top rails on the brake? We have one in the shop I work at but to be honest I have never used one much. How much do you allow for the slight radius for the bend?

    I measure out to .20, scribed a line. When it was installed in the brake, I more or less eye balled how thick the front edge of the brake was, I then set it back approximatly that far back to make up for the radius. My scribbed line was as close to the center of the radius as I guess it can be.

    I am no machinest by any means, just fly by the seat of my pants most times...

    Hope that helps.

    Regards,

    Thom

    This jig should work great with the new Tapco flat since the top rails are pre-bent. I made a jig using grass hoppers plans. It works. It is slower than my dph jig, but it is doable.

    Viking,

    Thanks for the info!!!!!!!!!!!!!!!!!!! So, have you bent the entire flat with a break yet????? I've seen the Ace template and it has a grey area for the radius so is that what you would bend by????. So, if one where to bend the entire flat with a break you would start with the top rails????? and then bend the 90s????

    Default Bending on a brake

    I believe, and someone feel free to correct me if I am wrong, that brakes are used for just the top rail bends.

    Is this because that is an easy bend?.....Yes!!!

    Looking at a flat, and then looking at a brake shows that the Mag dimples would be the major reason that brakes are not used for full bends.

    A brake would work fine if the Mag dimples were not there. The fingers on the brake would need to be modified to accomodate for the dimples, which most shops would not do just to bend a few flats.

    Not sure if anyone here has modified a brake finger, but it does not look like an easy job.

    Why not just follow this thread, and build the "Poor man's Jig"? It would probably take less time to build it than modifiy a brake finger.

    Just my humble opinion.

    Regards,

    Thom

    Built mine this week. I tried bending a few flats I purchased from Tapco a year or two ago. Very easy to bend and came our OK. My only problem were the sides of the flat were bowed in about 3/16 of an inch in the center of the flat. I imagine I am not taking enought time to slowly go back and forth as I press the flat into the fixture. I will keep trying.
    Thanks

    Default 555th Jig

    I had already built the poor man's jig, before I found plans for the 555th. I think doing it over again, I would build the 555th. Not that the poor man's does not work fine, I just think it would eliminate having to press to the final 90 degrees in the vice.

    If you have the materials for the 555th build that one, either way, you will see how fun it is to bend...even if you screw one up

    Regards,

    Thom
