25215 forum posts 3105 photos 1 articles	I see from Fig 14 on page 155 that the major dia for the threaded end of this part is given as 5/32" Any beginners trying to thread this part will end up with rather little thread engagement as this is just about the tapping size for 2BA. Turn this Dia down to 0.185" and then thread to 2BA. Hopefully this can be published along with the other anomolies in the earliest possible issue. Jason

5 forum posts	My first ME was 4355 with the Northumbrian on the front cover. I am keeping the articles for future use but I am beginning to wonder whether it's worth carrying on. Is it usual to have this many mistakes? I offer the following comments: Some of the photos show parts from future articles but not all the current ones. Not a problem in itself but could the current ones be highlighted to show their locations? I know black on black is the worst combination to photograph but electronic airbrushing could be used. I suggest the adoption of a registration system for all drawings where each drawing has a number and a current issue reference. A central database then ensures you are always working from the latest issue of any particular drawing. Industry has used similar systems for donkey's years and it used to be done manually, now it's a software thing and easily done. Pete

16 forum posts 4 photos	I would also suggest that the fork section is wrong, As far as I can tell there is around 1mm (3/64) of metal if the 3/8 dimension of overall outside length of the fork is 3/8 as drawn Pete
