    Hi All, Setting the two half bodies together so they line up, then drilling and tapping through. The first thing which I had to do was to cut off the end of one aligning plug, insert it through the two half bodies and tape over the end with masking tape to ensure it would not fall out when it...

    Hi All, Drilling the two half body attachment bolt holes comes next. This is another operation which is easy to describe and less easy to do without some planning and forethought even having some fancy equipment available. First, on one half body, both of the half body centre lines had been...

    Hi All, The inside machining on both valve body halves is now complete and some new simple aligning fixtures were machined up for the next operation which is the locating and the drilling/tapping of the two half body six attachment screws. They will be 3-48 NC which is in rare use today but is...

    Hi All, Next is the machining of the steam and shutoff handle passages in the two front half body halves. It is a lot of setup work as the body halves have different features on each side where one has to reverse the part and then pick up a previously drilled through hole to complete the...

    Hi All, Proceeding with laying out the front half bodies. This is not so straight forward as described in the LBSC construction article as it requires some thought and preparation. First, one needs a truly rectangular stout backing block which is true and square on all sides. Then one has to...

    Hi All, Moving on to the front half valve body machining. On the initial setup, everything is a straight forward concentric turning operation so I did not take any photos here. However, sometimes I just do things to prove that I can do it, so this involved a thin slicing operation on a very...

    Hi Don, And to add to your comment, having really sharp cutting tools. Probably up to 50% of the issues I have had in the home shop over the decades are not having sharp enough cutting tools. Don't get me started on that topic.

    Hi All, Just to quickly mention, with all of the above under my belt, the second valve body half spigot machining was a breeze. I was even able to use the thumb screw push plate in the 4 jaw chuck directly saving a lot of time and effort. So now onto machine the remaining two front valve body...

    Hi All, Finally, to the threading operation itself. The special made up threading tool itself had first to be set square to the spigot, set on centre height and be of the correct form. I have included just one photo to illustrate one of these operations. I wasn't going to risk using power for...
