13mm chuck too small. Options?

Hi I'm making a number of rollers using 15mm (od) steel tubing. There are a number of things I need to rotate the tubing like to file down the ends evenly to fit into a bearing.
I would have put the ends of the tubes in my drill and used that to spin it while filing it but it's a 13mm chuck and apparently chucks larger than 13mm are very hard to come by.
So without spending a fortune on a lathe is there any way or device to grip a 15mm object with my 13mm drill?

You could use an expanding mandrel - For what you are doing, a bit of wooden dowel slotted in one end with a wedge driven in would probably work.
Failing that, any Mens Sheds in your area ?Her courage will change the world.

Thanks that's a good idea with the mandrel. Not really sure what the men's sheds are, looked on the website and there is one on my street somewhere apparently. Is it a workshop open to the public?0

If the outer diameter is 15 the inner diameter is 13?
Similar to Freebears, I would probably get an sheet of paper and roll it into a tube, put the tube inside the pipe but add pritt stick glue (water soluble), now the hole is reduced, find a smaller drill (metal rod is better) to fit that reduced diameter and glue i in place with a hot glue gun
bodge it method 2: take a section of hose pipe or tubing that is slightly smaller that the inside diameter, cut it length ways so it expands and put it in the tube, now glue a suitably size drill in there.0 -

Read the website, it tells you what they are.Tall, dark & handsome. Well two out of three ain't bad.0 -

Good see they have started up over here.
I thought they only existed in Australia.0 -

Depends how many you have to do really.
You could make a lathe of sorts out of wood. At it's simplest three pieces of fairly heavy timer joined to make a "U" shape. Clamp the drill into the "headstock" by it's collar, make something up for the drive "dog" to be held in the drill chuck, and a "dead" centre on the tailstock end made of a bolt.
Lots of ideas for similar home made lathes on Youtube.
I don't know what sort of accuracy you'll get filing if you want to fit the tubes into bearings though.
Bound to be somebody local with a lathe if you ask around.0 -

If you need to machine the tubing accurately to fit into a bearing then you might find an internal clamping method with seamed tubing will give you an off-centre (or oval) external shape.
So if your tubing is seamed you need to do one of the following:-
1) Use external clamping (i.e. a lathe)
2) Remove the internal seam (tricky, but possible with a round file)
3) Design your clamping method with a 'hollow' to account for the seam.
If there is no internal seam then it will be a much easier job."In the future, everyone will be rich for 15 minutes"0 -
Well the less MSE but less elbow grease version might be a short stub of 13mm bar into the bearing. Drill the tube out to 13mm and slide onto the bar. Depends on how strong it needs to be.0

Check whether your steel tubing has a welded seam - it often does, and that means the internal bore isn't truly circular.
If you need to machine the tubing accurately to fit into a bearing then you might find an internal clamping method with seamed tubing will give you an off-centre (or oval) external shape.
Tubing is rarely truly round anyway, so machining off center is unlikely to make the problem any worse. I was guessing that the OP just needed to deburr the ends and maybe lightly file/sand the outside to fit the in to bearings.Her courage will change the world.
