:)Many thanks for all your replies to the above, especially the Link provided by DickyD.
I agree to the statements regarding instructions and the drawings are rubbish. would also add that some parts supplied in the kit come out at different dimensions quoted in the parts list.
With this type of kit containing inferiority drawings and some non-elegible part numbers I was thinking of designing some sought of head scratching mechanism to hang from the garage roof, directly over the bench. Changed my mind since I want to continue the build of this Trawler.
Incidently, if anyone else his interested, watch TV tonight at 8.30 for a six part series on UK trawler men.
Once again thank you all for all the valuable info. Ceres.
