I have seen many complaints on the internet by users of the Bamboo and the latest (as at 2011) Intuous4 models about excessive pen-nib wear due to rougher, more paper-like tablet surfaces. This issue, and in particular, what appeared to be a poor response from Wacom to the many complaints, nearly put me off buying a Wacom. But I searched the Wacom forum (there is one that runs to MANY pages on the subject of pen nib wear), and the key things I discovered were:
- the pen nibs are merely short rods of plastic (someone claims they are made of Nylon, which seems about right) having a diameter of about 1.7mm. - that the consumable, flexible 'chord' used in grass "strimmers" (or "weed eaters") - those buzzy machines used to cut the edge of your lawn - are made of Nylon, and many of them are about 1.7mm in diameter!
So I bought the Bamboo Pen as a first try of Wacom tablets. And I'm pleased. Good value. (I want it purely for handwriting straight to computer, for which I can recommend the free software called Xournal, now available for Windows.)
Then I went into the shed, cut off a short piece of the nylon chord hanging from the bottom of the grass strimmer, straightened it out (approximately) by hand, stuck it in the end of the Bamboo pen, and it worked perfectly. (It'd probably be best to round off the end of your home-made nibs with fine abrasive paper or similar before using).
So now you know how to replace your Bamboo's pen nibs FOREVER at a cost of approximately £0.00 + £0.00 P&P! Compare that to OVER £10 for 5 nibs from Amazon at time of writing.
