Hi VG.

Do you have a lathe? If you do it can be made to notch tube for a small investment.

I wish I had a lathe, but unfortunately I do not.

Drill press + hole saw?

that’s how old mate used to cut his titanium tube to make bike frames seemed to work fine, and then you have a drill press 

Yeh that's how I have been doing it, but trying to set up some angles is near on impossible. Also the chuck has a tiny bit of play, which reeks havoc on the holesaws with certain cuts.

I've seen this style used with some success in the past: https://www.trademe.co.nz/business-farming-industry/industrial/manufacturing-metalwork/drills-accessories/listing-2231751981.htm?rsqid=ba82531e18eb4aab987ce06015cfbfa8-001 

I'm pretty sure the arbour is upside down in all of those pictures... 

Yeh I think that's what I will get, well the HAFCO version, its exactly the same but cheaper. We get a small discount from MH, https://www.machineryhouse.co.nz/P090

I wont use it a lot, but will be super handy. I want to get more accurate cuts so I can tig things, as mig can be a bit/lot messy on tight tube bends.

Thank you gentlemen.
