Steeer tube not cut short enough
I've just cut my steerer tube. Measured how much I wanted to take off and added 2 mm on so that the top cap would fit flush to the stem. Put it all together and there was play. I reckon I should have taken a few more mm off to take account of the top of the steerer bung. I've put a 5mm spacer on top and it's all tightened up nicely.
Question: Would trying to cut a few more mm off the steerer be too difficult or impractical ?
Question: Do you thing I would like get away with a smaller spacer on top, say 2mm(would look better) ?

One thought though, so long as you set the preload with a 5mm spacer, once you have tightened the stem you could take off the top cap and replace the 5mm spacer with the 2mm one.
I do have a cutting guide but feel to cut a few mm off could still be tricky.
Thinking about what I did I took off 10mm of spacers form the top. I marked the steerer and measured that there was a tad over 4mm to take off. I added 2mm and took 6mm off. Thinking again I should have taken 10mm off.
What I've done as it is now with 5mm spacer on top should be safe though shouldn't it ?
It feels solid.
As long as the stem is supported inside by the expander, you’re good to go.
cut the steerer to ensure it remains long enough for the full depth of the stem's clamping area to be in contact with the steerer - with a secondary rule that you should not leave it so long that the bung will not extend the full length of the area that will be clamped
[some manufacturers may say you actually need the steerer to extend a few mm above the stem]
insert the bung, the amount these extend beyond the end of the steerer varies
depending on the design of the various bits, you may find you can fit the top cap and apply preload without a spacer, but typically you'll need one
fwiw i use a 2mm spacer
you don't need a 2mm spacer
just trim the mm off and put everything together. MF has just trimmed a few mm off his steerer and it is simple.
Alts, just file it off.
