Basically as described above, the units were meant to operate as a self contained unit, a generator vehicle [in Scotland it was a 12cyl Rolls Royce engine and it made a very nice noise at full throttle], the generator powered the emergency winder unit [winch]. All mines had to have a periodical emergency test, there was a dedicated position at the shaft side where the winder was anchored to the ground, the rope threaded over a pulley and a kibble lowered down the shaft. The kibble was a bucket that held 4 men, and that was a bit of fun from the routine having a trip down the shaft in the kibble. These units were immaculate and a credit to the maintainers, we only got to play with it during the test.

As a Shapeways shop owner - when you send a message to a designer, the designer gets an email message, and a notification of an alert on his page when logged in, good designers will reply, it may not be immediately as nearly all of us have day jobs and this is a hobby. There are also an amount of designers that will just not reply. Shapeways are unable to answer any questions about individual models as they have not had any design input and can only answer printing questions. Hope that helps.

Hi Andy The stuff wrapped around motors and transformers, I have some in my box will bring it next meeting. Sandy

Hi Andy Looking good, bit late now but magnet wire might have done the job. Sandy

Hi Andy Ooops you are correct I have the non working ones fitted to the push pull set. Sandy

Hi Andy I made the corridor connections the same depth as the originals, my only British train is an Edinburgh - Glasgow push pull set which I fitted Dapol short shank couplers when sitting on the straight the connections are about 1mm apart so I [may wrongly] assume that the MK1's are the same as the Mk2's.? If that helps. Sandy

Hi Definitely go for a frame, it does not add that much to the cost, the machine space is nearly the same so it is only pence more. Keep the frame tight to the pan, no more than 1mm from any part of the pan, I use 1.2mm square wires. if possible attach the pan to the frame that way when it is being cleaned after coming out of the printer it does not rattle about in the cage. Here is one of my models in a cage http://shpws.me/QtVc Alexander

I just ignore it. Shapeways original intention was that people who liked your stuff followed you and could get notifications when you posted a new model. All done with the intentions of a community spirit, till the spammers etc. got their hands on it. Other than one click to say do not post this to followers when you upload a new model it has not been an issue for me. Alexander

Correct about sketchup not handling small dimensions well. My work around is to draw 1:1 scale, export as a stl, then rescale in netfabb, never failed yet and you then get the advantage of the netfabb checks at the same time. I have heard that sketchup scale tool can be a bit of hit and miss but unable to verify this since I never use it. Another advantage in drawing 1:1 means that when appropriate your drawing can be easily rescaled if required, note that one drawing for all scales is not normally a good idea as wall thickness's can catch you out.
