Homemade tube notcher

I built a notcher out of some strap, and 2" channel iron. It took a few hours, and it was just scrap I had. It works as well as the JD2 I borrowed from a friend. Its difficult to notch next to a bend, though. I know.. there is a bit in the hole saw, I just set it up to take pics, and I didnt want to take it out.

Pivot the table to notch angles. I just mounted it to a piece of tube the size of the tube my drill press table was mounted to. Take the table out, and slide the notcher in.

yea, it is a pretty heavy duty press, it might not work in a light duty press, I dont know. I think part of the prob with notching in a press is the notcher is impossible to align with the press, so they fight each other. I wiped out a bushing in a HF notcher by putting it in a press real fast. This doesnt have the alignment issues, cause the saw is mounted right to the drill press.

The 2" channel keeps the tube clamped nicely.

Not to shabby! How does it do for smaller OD tube (< 2") seem like the 2" channel wouldn't clamp down centered/evenly on smaller tube. You could always add a piece of angle on edge IVI to clamp smaller tube.

Havent tried anything smaller. I thought I could get some 1.5" channel, and put it inside the 2" maybe. But, I think it will do 1.5", and I doubt I will notch anything smaller than that.

How do you handle smaller than 2" tube? Looks like a 1.5" or whatever might roll side to side inside that channel...

I wonder how long it's going to last before it loosens up and you start going through hole-saws like no other.

See post # 8 above. I will try some 1.5" to see if it will work. Im sure it wont go any smaller than that. If I need to notch smaller, and this wont do the trick, I will either make another for smaller tube, or make an adapter of some sort for this one. I didnt say it was perfect, but it was free! And it does make real nice notches.

Before what loosens up? The drill press is the only thing that I would think could loosen up. I have wondered about that, cause they arent designed to handle a radial load, mainly just an axial load. The bearings in the press are taking the load that the bushing in the JD2 style notchers see, if that makes sense. But, this is a pretty heavy duty press. we'll see.

Has anyone tried mounting a simple pipe vice to a drill press for notching?


$20 at HF....seems like it would work nicely.

Yes, the drill press. It's not a mill

bgaidan- I'm sure that will hold tube just fine... ppl tend to NOT make drill-press notchers for the above already mentioned reason and the PITA it is to fit tube w/more than 1 or two bends

I'm not saying it can't be done or it can't be strong with added bearings, etc, but I don't think this is gonna last.

Keep us updated after a couple hundred notches.

notcher

I also thought of doing something like this what I was going to do though is use angle iron 1.5"x1.5" for example so it would cradle the tubeing and it would work with many sizes. Plus then you could line the angle iron with some anti slip material i.e. rubber.

Obviosly this is missing the mounting system and the clamp but it should give you an idea of what I meant.

I would think that would work as good as the channel, and be more flexible on size. You would want to use some heavy angle, I have noticed my channel bending a little from tightening down real tight.
