ELMERS NO.7 square

[JCSteam]

I came across the plans for the Elmers no7 square, the engine intruiged me enough so that I went ahead and bought materials for it.
Below are the photos of progress so far, the crank bearing been the most difficult for me to achieve, it took me three attempts to get a good fit in the engine frame.

I'm learning a lot from this build including that I need packing material to stop the brass been marked, or some slide on jaw covers to protect soft metal. I also need to double check everything before starting the lathe up, as unfortunately when I set up for the long steam line, I hadn't tightened one of the jaws fully, which lead to an askew hole been drilled.

Jon,

For protecting materials use cut up soft drinks can, can't get much cheaper than that.
Plus, if you need to shim between two parts, then cooking foil is almost perfect, being a whisper under 0.001", for what you would be doing, that tiny bit under shouldn't make any difference.

Keep up the good work and carry on learning. The better you get at it, the slower your bin will fill up.

Thanks John, i know about packing the jaws, i was just not fully thinking and forgot until i saw the marks, id also got a couple of drinks cans sat at the back of the lathe ready to cut up. Just been a bit lapse unfortunately.
