Chris,
Yes I drill a lot of small holes two jobs on this Shay build come to mind drilling the frames and drilling the steam cylinder. I did them with the Servo drill press but the work was not very securely held and that can lead to more in the scrap bin.

Hi Dan,
I can see lead screws for the Y & Z axes, but do not see any for the X? Does the spindle with the horizontal motor move?  It almost looks like you could do milling on it. I looked up the company but did not see any machinery on there.

Gerald, the table is on round linear bearings and you simply push it into the drill bit. There is a mount in front for a dial indicator and a rod on the table that is adjustable that engages the dial point. The back rail has two stops to limit the table travel.

Here is a link to the specs:

Progress on the wheel sets. I just have to trim the length and diameter of the bearing fits. I just had to see a trial assembly.



I will be packing up my mobile shop tomorrow for the trip to the International G1 Steamup at Diamondhead MS.

Dan,
That just looks really cool!
So, I'm sure it's back in your thread somewhere, but did you make all those castings?  They look really great!

Kim, I did all the castings except for the gears and the line shaft bearings. I only cast silicon bronze which is a bit hard for a bearing so I used Shapeways for the line shaft bearings. The gears were cast from a part made with a 3D printer. I would have used Shapeways but they do not cast a white bronze which I think looks better,
