Does anyone have a good way of figuring out how to notch or fishmouth a piece of tubing? I have a tubing notcher but it doesn't allow a very sharp angle. |

Here is a link I found awhile back on calaculating on mitre joints: http://www.metalgeek.com/static/cope.pcgi When I was modifiying my new Buggy frame I used an contour gauge. Its the one with about 100 wires that conform to a shape. Some I just eyed up and cut. |

I built my racecar with a harbor freight notcher, and it worked alright, till it wore out. I just got a JD squared "notch master", and it is amazing. But back to the question, how sharp of an angle are you trying to cut? I think most notchers will cut 50* and more if you take the center bolt out. anything over that, is ALOT of work with a cut-off wheel, grinder, and bandsaw!

I used a chop saw to make all the notches in my buggy. It works pretty good. |

I've got a couple of those pipe masters, and I don't use them very often. They can be a pain in the a$$ to trace out, and by the time you do all that, you can usually just hole-saw it and be done. |

thats how I used to do it, but the tubing was so thin on my last car, that it would just melt it out

I lubed mine up to make them slide a little better and sometimes i have to shape the curve a little by hand but never have a gap to fill like i do when i use my hole saws.. |

Try a place called Harbor freight. It works great and around 100 buck can't beat it.

Again, I must be building the poor man buggy. I use the tube from an empty paper towel roll and cut out my pattern with a pair of scissors. Then, using a grinder, try to mirror the shape. It does not always work perfectly but the price is right. Dan |

If you have access to a knee mill(bridgeport) you can use it to notch tubing. The holesaw arbor I have is 3/4 dia below the hex part. You can grab it with a 3/4 collet. Then set your vise up to one end of the table. This lets you move the table around to position the tubing. The great thing about this is it lets you take off just a tiny bit at a time. It's so much more rigid than the regular holesaw notchers that the cut is truely straight and it really fits very well with no grinding. You can also notch in the middle of a bend. John |
