I present a few more action shots on the X3 mill. The DRO is wonderful for cranking in the proper cutting dimensions even after a careful layout. The layout marks confirm the location but the caliper like accuracy of the DRO makes sure the cut is exact.
These parts will be used to braze up the coupler pocket for the A3 tender. I am not showing all the work involved, just some of the unusual. The saw here is the same thickness as the brass plate. I am cutting two layers at the same time. That way opposite sides will be exactly the same. The pieces will be assembled like an egg crate.
The cuts are made on one side of the vice but unseen inserted on the other side of the vice is more brass material the same thickness. This is to keep the vice clamping equal so that it doesn’t “rack” when tightened.
I will be posting more pictures of how the coupler pocket is assembled and finished.
