Don't be fooled, any help is good help
I'm in Ramsgate, Kent. Are you a Brit over there

Comments like "on the back of a fag packet" suggest it.
Also in the background of the pic is an example of my other interest, I'm recreating some of the models from the old Ramsgate Model Village, using original construction methods.
Well can I ask for a bit more help from you? what scale lengths and accuracy did you order for the DRO on your Bridgeport? I have been in touch with them, seems easier than shopping in the high street here
