Parts List


This is an approximate parts list. Without dismantling the model it would be impossible to give an absolutely accurate parts count, but if you are considering attempting this model this should be close enough to get you started. A text file which can be imported as an inventory directly into MeccInv 8.0 can be downloaded here.  The "Total" column gives the overall requirement and the later columns break this out according to the various sections in the description.

For the long axle rods I used #20 oil hardened drill rod. This is 0.161" in diameter, which is 0.001" over the nominal Meccano size. However because it is very close tolerance there is no problem with standard parts fitting. Some replica brass parts may be tight in which case they can be opened out with a reamer - I use one with a diameter of 0.1615".  Both the drill rod and the reamer can be obtained from www.mcmaster.com.
