Well I can say Mounts drawings are outstanding. Currently I am building Galloway Non dead centre engine I just made a load of parts to the drawings without any assembly until two weeks ago when the “finishing fitting” had to be started with assembly. All the parts fit and I have found only one part with a problem. Don’t know if it’s Mounts fault or mine. His drawings are fantastic.
Some rather strange dimensions for parts only became obvious once the parts were assembled It’s a very exciting build , the motion is hypnotic with so many levers moving at different rates and directions
The drawings fit nicely in a A 4 folder and are easy to access They slip into ck
lear walkets to be used on the machine, and in the file the blank of the previous drawing contain my sketches and notes on how to make the parts Very very easy to handle. With Mounts parts list with part numbering and drawing numbers all given in a pair of sheets which also indicate the materials required finding part drawings is very very easy. I once tried to build a loco to clarksons of York design. Now they were BAD BAD BAD,!! Blurred, mixed up. Unclear with a huge number of missing dimensions. I did complain, and got a reply… they are only fir guidance, it’s up to the builder to sort out the exact details. Strewth!!! !,, I cannot fault the excellent design work Mount has undertake with this design
linnen drawings were for multiple productions of the same build at a time when reproduction was by tracing and very expensive. This method is now completely obsolete. I did a factory visit to see injection moulding tools being made. No drawings used. It was all by 3 d modelling with g codes sent direct to the machine the 3d models were only there to enable the machine operator have a clear insight to what he was about to produce
Thanks to cad and computer drawings things are these days a lot simpler
