Hi Allan,
just uploading some more pictures, i hope they answer some questions 
I was given the frames with frame spacers already cut, filed and drilled with axles and eccentrics already machined and the blank wheel castings.
The horn Guides as described in the book are hot pressed needing just minimal filing, mine are cast and from the pictures you can see my start at milling the first one to size, its shown me that i need to fit a more accurate way of measuring the Z axis as its a bit of guess work at the mo. I taken a picture of the horn guide drawing detail to show what the final outcome will fit to.
Once they fit into the slots in the frames i then have to drill holes in the guides and frames to enable me to rivet them in place, something i've never done on such small scale!!
Rivets and snaps are on order so hopefully i'll get this all progressed in the next couple of weeks.
Apolagies for the rusty vice in the pictures, were currently renting and the lack of insulation in the garage is making my job of keeping rust at bay quite difficult at times 
Now a question for you Allan, how'd you do the link to my pictures, i seem to struggle to work it out 
On that note, please click the link in Allans post to see the current pictures 
Cheers
Chris
