I can't see the angle on the bolts well, but I wonder if a gusset plate could be fixed along the bottom of the tube and onto the boiler? Could be shaped as desired not necesarilly a traditional triangle gusset

Regarding stress on the boiler neck: good question! I intend to add a ring of insulation around the boiler and hide a brace inside it.

Looks very interesting - I know it's just a mock-up, but that's quite a bit of weight hanging off that boiler neck, both from the weight of the group, and even more stress when pulling the lever . Will there be more bracing or a frame around the group to boiler junction?

Not sure what happened during Covid… but time and life seemed to blur into some odd never-land… but I did make progress and am back at it! Progressed to the first rough mock up of a frame. Just experimenting with shape at the moment.

I soaked the whole thing in penetrating oil a few days… then some gentle heating, followed by more soaking in penetrating oil. Then clean it off well and wrap it in wet leather, clamp it in a wooden vice or roughened wooden blocks in a vice then turn the shaft…. Slow and steady it came off!

What did you do to unscrew the piston from the rack? Is it because this is a newer machine than other groups I've seen? Paul Pratt told me he has never been able to unscrew the piston without damage, which is why I have never attempted to unscrew mine, although he works on really nasty machines sometimes.
