Bernie has been hard at it making another pattern. This one is the Follow Block for the Saddle Shim.

The photo Mike posted is the "follow block" used in the casting process.  It will be used to support the shim pattern.  It will also be used to help assemble the shim pattern.  When a pattern is curved and does not have a flat surface to rest on the follow board, a follow block is used in the initial ramming stage.  The shim pattern sits in the follow block during this stage and when the flask is turned over to ram the second half, the follow block is removed and the second half is rammed up.  Shortly I will show the shim pattern fully assembled.

The new boiler for #10 is a slightly larger diameter than the old one so the saddle shim has two curved surfaces--a smaller radius to rest on the saddle and a larger radius for the smoke box to rest on.

Mike, thanx for posting this as I still haven't learned to post photos.

Really enjoy seeing fine craftmanship  used to scratch-build  elements, tools to rebuild an historic, useful machine like No. Ten.

Bernie,  can any parts of this pattern be used for #11 castings?  Can't wait to see the finished product - another work of art..

John,

This part is strictly for #10.  It is a one-off and the pattern will only be used only once.  #11 will not need this part as the saddle will be properly contoured to fit #11's smoke box.  This making of a pattern for one casting is typical for steam locomotive repair.  The part is important for the repair but only one is needed to keep the choo-choo running.  I have made several patterns and in the middle of making clam shell door patterns for CNJ 113 which will only be used once.

This kind of project would be a good candidate for the 3D sand printing process discussed in earlier posts.  Since I don't do CAD, I still do things the olde way.

Does anyone at this point have an idea when the No 10 will go back into service?
