Took a couple of shots with a ruler to send to my old friend, Bryant, who builds my wood bases. I wanted to give him a head's up about sizing. It's not the final value, but it's close.
It's going to be about 1 foot deep.

And about 21"wide (by about 1 foot high). The prop shafts and the bulkhead stiffener in the fire room made the width extend past the drawing's edges.

Today was one of the first where progress was in retrograde. I had a printing anomaly of the MRG… there was a significant growth of resin on one interior wall. I didn't discard this, but went back and reset it in the slicer with more supports in that area and printed it again. While it was printing I took the Dremel Flexi-shaft and a carbide router and sugically removed all of it. You can't see this when the gears are installed, but the lump would impact their installation.
Here's the malformation from two directions. I had already started attacking it in the damage when I took the image.

After cleaning it all out with the router, then sanding drum and finally a diamond coated burr, it's functional… Functional, not pretty.

Much to my dismay, the reprinted part actually came out worse. With the delamination I suspected there might be some resin on the vat film. I emptied the vat, made a mess when my silicone funnel with its filter tipped off the resin bottle and made a royal mess. There was no resin stuck to the film. I refilled the vat and started printing again. The growth looks exactly the same as the previous one and my corrections did nothing. I have no idea what about the design is causing the excess resin. But this one also has delamination on top and that would be visible, rendering this print scrap.

Ths delamination...

I tried the gear sets in the repaired part and they fit without interference, so the correction worked.

I correct output shaft just came off the printer with the second upper frame print and is in the post-cure chamber, explaining the water pipe used to support the bull gear.

Lastly, I had another shock. I made beautiful prints of the two cutaway gear box covers. I mean they were perfect! Except they weren't. For some reason, the designer had the reduction gear bores way undersized. I don't know what he was thinking, and I'll have to have words with him.

I left the shop and went back to SketchUp to fix this. It took hours! I've said this many, many times. It's often more difficult to repair an SU drawing than to do it in the first place. The fixed covers are now in the printer. I've officially named it THE MACHINE!.
I also noticed that my innerds desgn of the gear case doesn't have an inboard bearing cap for the bull gear shaft. There's a bearing on the lower half, but nothing on the upper. I drew up a bearing cap and will print it separately. Clearly I missed something when looking at the framing diagrams.

I also found out why the LP/Condenser height was off by 3/16". Look at this image of the equipment below the drawing sheet.

It will be easier to shim up the condenser foundation than to trim the HP foundation. The printer doesn't lie. If I drew it wrong, it will print wrong. Hopefully, tomorrow will be in a more positive directly.
