i just made a note of the bearing codes and bought the bearings from a regular bearing supplier as and when I've needed them (my main pivot went first, so I did the linkage bearings at the same time anyway). They are regular sizes and widely available.
And youre right winding people up doesnt affect the quality of the product, but it does alienate potential customers when there are myriad other more well established suppliers in the market. Companies live and die on their customer service as much as their product. Getting a few people on side with freebies is a transparent attempt at damage limitation, and doesnt speak of his ability to deal with regular (ie. paying) customers. Be genuinely interested to see how he handles someone taking up a problem with him, which would be a more accurate measure of him then either his leftfield posts or his freebies. I actually admire his attempts to turn a hobby/obsession into a business, but he needs to either grow up or at least take a breath before hitting a keyboard.
