Cutting tube

[Modelholic]

I'm trying to accurately cut some 5/16" styrene tube into 3.5mm lengths (I'll need around 20 pieces for 1/350 20mm gun tubs)

I've been using a cordless drill as a lathe but it's just not accurate enough.

Any ideas?

TIA

Tom

You can buy a pipe/tube cutter for such small sizes

cheaper versions are available

PS. On such short lengths I use my pipe cutter to just start the cut around the tube then I finish by the 'rolling under a blade' method. The pre-cut groove keeps the knife blade true

Scribing with a caliper can work .

Then the 'roll' method to cut.

Here is a pipe cutter like mine
