    Default Scalloping round tube/pipe for T joints

    For anyone interested, instead of using a grinder to scallop round tube, I use the bandsaw. I first set the BS at around 39 degrees then move the stop out a few inches to clear the blade. I then measure from the stop to the end of the tube and make the first cut, then swing the tube around 180 degrees set the end of the tube the same distance from the stop and make the second cut. I’ve been using this method for years, better than making sparks fly everywhere, makes a perfect joint and it's a hell of a lot quicker – particularly if there are a lot of scallops to do. The pics should be self explanatory.

    That's how I do it also, except that I set the stop. Thanks for showing others how to do it.

    That's nice. I have another option but it's perhaps not as nice. I inherited a hand operated hydrocrop tool. It shears off the pipe and flattens the end in one go. Like I said, not as nice though.


    Cheers,

    Thanks for that. I learn something new....

    I did this a few weeks ago, but I used my Mill. ( I was lucky to have a 25 mm end mill. )

    Your method works best if you don't have a mill..

    The belt sander does a good job and you can easily cut any angle, very handy if you need a few pipes cut. The only downside is you need to have a few drum sizes. I do have an angle calculator that can be downloaded from the web for cutting on the band saw, I notice that there are now apps for mobile phones as well.

    Now your just showing off. That join looks like it would be waterproof even before it's welded!

    simonl,
    If you saw my welding skills you would see that I need very even gaps to do even a halfway reasonable job.

    Yes indeed the belt sander does a good job.!
    Especially if the said belt sander happens to be a Radiusmaster. I am insanely jealous of course!

    Hi Graham,
    Thanks for your reply.My belt sander/grinder is one I built some time ago,they are very handy for all sorts of work. I did post it up under "Your Latest Projects" posts 138,141 & 241. I now have three separate tool bars that I can change very easily-no tools required. If you have some spare time building one is a great project.
