In fact one end has already been shortened by about that much and I have had to thin down the inner tube a little to restore the fit with the endcap. I'm not sure that there is any scope for further thinning without overly weakening the tube.

If the taper is something like 20mm in 400mm of length, the change in diameter from cutting off 10mm would be something like 0.5mm. Are they really made to that level of precision?
