I understood these 3d files have been created from 3d scans of the original boat?

[He Who Shall Not Be Named]

Thanks David. Howard the 3D Print gentleman must at some point seen photos of the museum sub. So I wonder if he has research information that Albacore tested the blade count in the above parts photo too at some point?

We know from your excellent accurate historical article you did decades ago and decades ago inspired me to join this 'clazy' hobby, you mention and I still remember Albacore tested several propellor combinations in Phase IV configuration.

Perhaps that involved different blade counts as well as separation between props too? The Portsmouth NSY foundry and milling machines in the Propellor department must have been a busy place then cranking out different hydrodynamic test propulsors. I know in the UK there was a 11-blade sickle blade shaped prop tested experimentally on one of the Valiant Class SSNs, but apparently it was at the very limits of the CNC technology then at that time and it lacked the robustness of a more usual 7 blade count. A one off,



In 1/48, at 210 feet in Phase IV, would be perfect size for the water internal space and the car truck transporting at 52.5 inches. Id love if available the STL files I can resin print one for myself.

"Now back to the regularly scheduled program"

To the best of what I could find, no reference to variances in blade numbers. Just distance between the discs was altered and propulsion perimeters measured and recorded. I'm sure David Taylor went through a slew of propeller types, distances, and geometry before sending the drawings to the NSY for creation of the actual castings we are now so familiar with.

My agreement with Howard is to produce tools and parts from the masters he is sending me (more to come). From that tooling I'm to get a 'kit' as does Howard -- his to be assembled and painted. Contact him, he might be agreeable to letting me produce a kit for you. It's going to be his product, not mine. I'm only the idiot tool-maker on this job.

[Albacore 569]

These were sent to me as is (obviously, whoever did this insured he had the blade-count right; not like one idiot we know) and were 3D printed. I believe the scale is 1/48. Maybe Howard will chime in here and tell us more about these pieces.

Really enjoyed your video David!

Which one, Rob? Did you make yesterday's Zoom meeting?

3d files can be easily scaled, all depending on whether the creator wishes to make them available.

Hi David, the Albacores parts are they in 1/60 (Asay's old kit) or in1/96?

And do you make an aft prop set with 7 & 6 blades too? If in 1/60 I might purchase a set?

Parts look beautiful.

MOST helpful, Romel. Clear decal paper on order. Excellent!

Similar to this one?

Exactly that one.

I woke up stupid this morning. Thinking of representing that 'city crest' we see at the leading edge of one of these boats sail.

Some fine painting on decal film seems to be in order for the near future. Will be good to once again haunt my drafting-room upstairs. A fun departure from the usual grind of the shop.

David, that Albacore sail is outstanding. Truly one of your best yet.

Nope. Not my work. Evil robot printed. Sent to me by Howard to be worked up into production tooling.
