|Three Helical burrs - Helical, W(h)orl(e)d and HELLical!|
Earlier this year I was chatting to Derek and he told me about his design for a significantly harder version of the Helical burr which he named the HELLical burr and was delighted to be able to get a copy from Steve. This was by first experience of a home 3D printed version and was very pleased to see how fabulously smooth the version was. I gushed about that one here and even went so far as to post videos of the disassembly and assembly to help people who were truly stumped they can be found here and here. The HELLical burr was really was extremely tough and, having practiced it so much for the video, Steve decided that he would use my skills at the last MPP! He forced me to disassemble and assemble a fair number of the ones that he had made to work out which had acceptable tolerances! Since then I think he has made and sold a considerable quantity all over the world.
I was aware that Derek had been working on another design with Steve but did not realise how far along they had got until about a month ago I realised that I had missed an announcement on Facebook that the third design, the W(h)orl(e)d Burr, was complete and actually being produced for sale! Unluckily for me the whole lot had sold out within a single evening! I tried not to send a whinging email to Steve that I had missed it because I knew that he was really busy with his new job as well as starting the massive task of printing his exchange puzzle for this years IPP. My friend Jamie did manage to obtain one of the new ones and posted on his FB page that he was finding it quite tough - this didn't surprise me initially. But I was surprised that even after a week or so he had not managed to assemble his copy. I know Jamie is now quite an accomplished puzzler and if he struggled that much then I really needed to try for myself - I was expecting a horrendous task. I was really pleased when after just a few weeks Steve put up another batch for sale on Paradise and I nabbed one straight away. It arrived (with a nice note) a few days later.
