Z-axis design - help sizing materials please!

I haven't bought supported rails from Chai, but I have bought a water cooled spindle and some ballscrew support blocks (BK12) from him and can vouch for his good communication and good service. One of the square nuts in the support block set had a poor thread, but a quick email to him had one on it's way over from China. Remember to allow for import tax, duty, handling etc. in case Royal Mail search your parcel, but even with these the price is still tempting.

That sounds good. I did a search on his feedback for 'quality' and found lots of praise and only the odd bad one.
Do you think tax is likely? Did you get charged tax?
He's now listed the rails for me :)

Did you get charged tax?

Listing my various imports:
Spindle no, bearings no, one set of profile rails no, one set of profile rails yes.

So possibly not, but allow for it.

How much were the rails that you got charged for? Customs only change if it's above £18 if I recall correctly, so it depends to what extent the seller fakes the value on the form since alas, no rail is that cheap!
