Notching Tubes and Pillar Drills
I need to notch tubing so I can butt them against another tube the same diameter for the chassis.
I am struggling to find a locost solution.
I have looked at tube notchers, but can only do up to certain angles (the best i've seen is 60 degrees @ £190)
But I need to get a Pillar Drill anyway.
By budget is not great, i need to do it as cheap as i can, but still getting a good machine that will last.
What have people brought, as anyone got or used the cheap ones from Machine Mart, that are about £60... just seems to cheap to me for a pillar drill
press.
If I get a pillar drill then i can make a clamp to hold the tubing, and then do what ever angle i require.
What type of finish do the metal circular cutters give to the metal. I was thinking for the holes for the brackets for the suspension, or is it best
to get these done professionally.
I am looking to use the pillar drill to cut through nothing more then about 5mm of steel.
I know i have asked several questions, just need to make sure i am not wasting money on pointless power tools (if that can be done!!!!!)

cheap pillar drills are no good for notching at angles, the teeth snag and the shaft will bend or flex. Ideally, a proper notcher, even one you attach
a seperate drill too, or a lathe, with the side cutter spinning and the pipe in the slider vice (or whatever its called  )

If you're desperate you can cut it with an angle grinder a bit at a time 'till it is close then file it with a half round file. Keep
putting the piece you are cutting in its final position to see how close you're getting. Time consuming but cheap.
Edit to say perfection isn't required if you're welding it up. A small "root gap" is sometimes beneficial

If you do a search there have been posts about tube notching /mitre in the past IIRC?
Type in tube mitre , really must work out how to put in a link.

Cutting a mitre was the type of thing I would have worried and fretted over.
Nowadays, I lend a hand to some guys who build very nice racing cars. They just cut it to an angle then attacj it with the 4 1/2" grinder to
fettle it to fit.
With a little patience, it always leaves a nice job.
They have a Thomas saw and it runs a toothed blade turning at maybe 60rpm with lots of lubricant.
That and a grinder and you can cut anything.

I use a cheap pillar drill from B&Q with various vices and clamps.
The biggest holesaw I have used is about 65mm.
The problem is to get a drill which will run slowly enough so you won't burn the teeth off the holesaw
For the occasional joint I can't holesaw I use a mixture of saw, grinder & file.

This is what you need for fishmouthing http://www.ozhpv.org.au/shed/tubemiter.htm there was another program but looks like the sites down.
As for cheap pillar drills personally I wouldnt bother Ive had one for ages that I just dont use its totally cr@p you can stall it easily and its
inaccurate the main fault being a useless lower bearing.
