953 /Carbon Semi-Lugged Road Bike

953 /Carbon Semi-Lugged Road Bike

I have previously built a Road bike using Reynolds 953 and Llewellyn lugs with a Dedacciai carbon fibre rear triangle. This was something of an experiment as, whilst it was a standard thing to do, I was unable to find any real information about how to go about it, especially in relation to the glueing process. I have now been riding the bike I built for two and a half years and have had no issues with it other than a minor problem I will mention later. Using the experience I now have I am going to build a similar frame. This will again use 953 oversize  main tubes (35.9,31.7,31.7) with stainless Llewellyn lugs. The rear triangle  is supplied with it’s own bottom bracket so this has to be fillet brazed in. Although the rear triangle is supposed to be a  Dedacciai Firebox as before, from Ceeway, it is a slightly different shape from the previous one and is marked “Black Box and Black Tail”.

Introduction to Milling – another Axminster skill centre course

Introduction to Milling – another Axminster skill centre course

At the end of November I attended a two day course as an introduction to using a milling machine. This will be another machine to complement the lathe in producing custom bicycle parts. Now I will be able to make things that are not only round, which is the limitation of a lathe. The milling machine enables the cutting of shapes that are square or curved or stepped, together with slots, so I should be able to make various types of dropouts and no doubt other things. It can also be used to mitre tubes. The course costs £275, including lunch and refreshments, a slight increase on last years fees. There were 4 students to one tutor and I was lucky enough to be taught by Bob Rolph who had previously taught the small lathe course.
Students use the Axminster SX3 machines for the course (other machines are available) and there is no hard sell to purchase Axminster’s own products.
