Re: GM&O 40 ft Automobile CAr
Scott and all, Thanks for the kind comments. I cut my shim brass much like styrene. I use a sharp xacto blade and using a straight edge. score a straight line a couple of times. I then place this in a PE (photo etch bender) at the fold line and bend the sheet back and forth carefully using a bending bar (a 6 inch or 12 inch steel rule from an old Starett Combination Square). It then usually snaps of on the 2 or 3rd bend. To fold, I use the same method, but follow up using my UUM-USA Micro Saw to deepen the groove about 1/2 the thickness of the brass I am bending. Next I insert in my PE Bender (From UUM-USA) and use the Starrett steel rule to bend against.
The PE bender I use is more like a simple vice and are very inexpensive from UUM-USA. For folding longer pieces up to 150 mm (close to 6 inch) can be seen here http://umm-usa.com/onlinestore/product_info.php?products_id=67&osCsid=4ee4c1a824b807ecd36fd1d139aa1c7f
I also use two shorter 60 mm versions of this http://umm-usa.com/onlinestore/product_info.php?products_id=58
and this newer version with a bending brake on it http://umm-usa.com/onlinestore/product_info.php?products_id=59&osCsid=4ee4c1a824b807ecd36fd1d139aa1c7f
