RR440 Have the local sheetmetal shop bend one or two part's long enough to cut what you need out of then weld . Are you trying to make a rectangle tube ? I made runner's for a intake manafold with one seam four bend's made a push clevis for my press and a bit that would fit in the confine of the finished part made the bit out of hotroled bar with a radis and cut a grove in 1 1/2 Aluminum for the female with the corect R tool ID. R+mat thickness = Grove R. I kept machining the grove untill the bend was corect when it bottemed out Drilled a series of holes in the edges of the plate to put pin's in for back stop's I think I tryed four times to get the part wright after doing a lot of math calculations to try to save material Good Luck Kevin |
