I know this subject has been brought up before, and  I looked back in the archives to check it out, but I'm thinking about  getting  a 48" brake for bending some brackets, some L metal strips and  just generally light stuff. I don't want to build one. I'm already building an  airplane. Looks like they are around a hundred bucks or so. Has anyone  any experience with these. I know there are a lot of different brands but  generally speaking what do you think?

Must be that excellent rivet gun you have. Or is it still working?

		   Dave, if your going to bend L brackets its very 

 easy to just bend them in a vise with a form block

 that has a 1/8 radius. After forming the meatal over

 the block finish it with a pair vise grips with two

 bars glued or welded to the grips. There's always

 a way to make parts without spending an enormouse

 amount of money. RJS Do not archive

I suppose you are right.

Hi Dave,



 I bought one of the really cheap bending brakes (18" I think) from Harbor Freight.  It worked OK but was not easy to use because of the way the clamping bar had to be held down with vice grips or C-clamps.  I got a nicer one from Grizzley (24") and had to make several modifications to get it to work at all.  It includes a clamping mechanism (toggle clamps) but they needed to be cut off the main section to work at all since they were so poorly aligned.  



 I also added a piece cut from a 1/4 inch aluminum extrusion which had the 1/8" radius already built into the edge to the clamping bar..  This is needed to form most of the parts on Zenith designs since they call for that radius on all bends. Both small brakes I bought were not designed to include any radius in the bends.



 I rely on ZAC for bends over 24".  Oddly enough, I have found that most of the parts I wanted to replace were actually small enough to bend on the 24" brake.  There doesn't seem to be many between the 24" limit and the huge bends in spar parts.



 Have fun,



 Paul

Dave,



You might want to ask around the local EAA chapter, I did and look what was loaned to me:

Here is a picture of the 48" TennSmith attached:



I did wrap a couple pieces of .040 around the nose to get the radius I needed.  The are just two way taped in place.

OK, OK,

  

 You guys talked me out of it. I'll just do my bends  with the stuff I have and I'm sure they will be fine.

  

 Once again I have been temporarily brought back to  my senses. I wonder how long it will last this time.

  

 Thanks,

Dave Clay from Temple, Texas came out with a very  easy to make design. It took me about 4 hours to put together. I actually have  an 8 foot brake with a nice 1/8 radius for under $100.00. Thanks to  Dave.

 It is published on the 601 web site.

 Hope this helps
