tube notcher link working now

a little program i found usefull some time ago

A tube mitering program for Windows to print on any printer.
The other one is a Hypercard application for Macintosh,
and once I dug up a Mac and a PostScript printer, it was very
useful. However, it doesn't take wall thickness into account,
which is important when doing small angles or equal sized
tubes. My program also deals in metric units.

File/Settings... puts up a dialog box. You input:

* Diameter (in mm) of tube being mitered
* The wall thickness of this tube
* The second tube diameter (the one it abuts up to)
* The included angle in degrees.

It paints the picture on the window, and File/Print... prints it
on any connected printer.

There are two curves - the dotted one is the template you
would cut if the wall thickness were zero (similar to the
HyperCard program's output) and the solid curve is the template
corresponding to the requested wall thickness.

If the mitered tube diameter is greater than the second diameter,
then the second tube passes through two holes in the mitered tube.
This situation is handled by continuing the template on the
other side. Small gaps may appear in the curves; this is a known
"feature" of the way the program works.

ps use the very thin cutting disc

That sounds ideal for me but how do I get hold of it?

Wow, that looks super usefull... although I have built a tube notcher from marvin storey's internet designs... This will still be a handy tool! Thanks...

 

[Danger]

Can you post the website that shows how to make a tube notcher?

 

[HughF]

I'll dig out the url for you soon...

Seen one somewhere for a belt linisher, can't find it just now though!

Why bother? Unless you are doing lots. I use a hole saw in a pillar dill, or by hand with the help of the 'tube mitre' program. I should mention the table of the drill is adjustable for angle.

i found this sites some time ago, maybe of interest as have lots of detail

Chester Machine tools do this this one:

Not sure if it meant for use with a pillar drill or not?

I got this one from the states it works great you need a lathe though and it is adjustable so you can get the cut spot on.For andgled intersections you adjust the tool post which is already callibrated with the deg.

 

[tube chassis??]

Sam - what are you building there?
I bought a tube notcher for use with a drill from the uk but I didn't think much of it and sent it back, so I got this one off of ebay, the guy is in the states but it wasn't a problem for him to ship it I just had to pay the duty on it before it could be delivered. I used it this morning and it is plenty good!

CNC machined from billet ali and steel, why isn't this sort of decent made tool available over here?

 

[Sam]

I have seen them on another forum a lot of guys are using them and they work great keep an eye on the cutting speed there is a chart on the box that the cutters come in and a bit of spray coolant won't go a miss either.
The only drawback I could see with the billet notcher is if it gets a knock it will not cut perfectly central through the tube but if that was to happen you could shim to compensate, there again the drawback with the one I have is you need a lathe.
There are a lot of great tools from the states at great prices if you are buying from the states tell the guy that you will pay the duty when it comes into the UK they do not check everything sometimes it gets through or if you know someone there get it delivered to them a few companys give free shipping within the USA over a certain value and get them to send it over as a gift I think it is upto the value of £65.00.
I bought a quick action offroad steering rack and pinion there for $135.00 we were getting almost $2 to £1 here they were wanting £387.00 plus v.a.t. chum.(Treasure island what)I got a bucket load of bits sent to my wifes cousin and when Christina (other half) was working in Boston she picked them up and brought them home in her luggage.
The chassis is a two seater buggy with a suzuki 1000cc engine I hope to keep it under 400kg. power to weight ratio it should keep up with a WRC Subaru.What are you looking a building yourself.

You can get JD2 benders from tubela, in Essex, they'd probably be able to do the notching tool too?

 

[tube chassis??]

Sam - I am building a tube chassis for a carlton, will have a small chevy up front as I intend to go drag racing eventually!
Luke - if only I had known a month ago....!
