[size=150]Hi there Pete,[/size]

[quote="greenglade"]Here's the link to EJ's page on Britmodeller https://www.britmodeller.com/forums/index.php?/topic/235057680-hms-hood/page/10/#comments[/quote]
[size=150]Thanks for the message. This is a thread that I have always followed with utmost interest, as I have a 1/350 [b]HMS Hood[/b] and a 1/72 German U-Boot U66 in store as my next projects.
EJFoeth had already updated the links in his previous post, and had also sent me a PM to let me know.

Thanks very much again, and warmest regards from this side,

Willie.[/size]

Great research as always! Is the floor of the aerial tub flat like you've shown? My brain is trying to conving me that it has a conical slope downwards towards the insulator bulge... Probably just the weathering playing tricks on me though.

I think "microscopic modeling" really captures what's going on here. Incredible work. You keep pushing the envelope. Of course, part of me thinks that's so you'll never actually have to [i]finish [/i]the model, but that's just me.... :heh:

Fantastic attention to detail, and microscopic modelling. :thumbs_up_1: :thumbs_up_1: :thumbs_up_1:
I would say 'as usual', but I feel it is getting more detailed nowadays than before... ;)

Many thanks for the detailed description. Very educational! :thumbs_up_1:

Pics will keep coming; I'm went back to a 32 hours work week with a day of Hood modelling per week (if all goes well) :smallsmile:

The images are scanned from three sources (can't remember which image came from what but most from source #1):

1) Manual of Seamanship vol 1 and 2 (1937)
2) Shipyard practice as applied to warship construction, McDermaid (1911) (https://archive.org/details/shipyardpractice00mcderich, I have a hardcopy too)
3) Practical construction of warships, Newton, 1941

There's a ton of information in each of these volumes that has been quite helpful with various bits around the ship. I scan them at high resolution and apply a dash of photoshop to clean up the images.

EJ the Davits are superlative and the jig most clever. But what i like most is:

:big_grin: Keep it upp!

An excellent piece of research EJ, thanks for sharing what you have discovered. I'm in envy of the quality of your pictures, may I ask where you found these? Some I recognise but I've never seen them this clear before.

Cheers

Pete

By that standard my 0.4 mm diameter Davits seem coarse and simple :whistle:

Amazing work on that davit Evert-Jan! Wow! :thumbs_up_1: :thumbs_up_1: :thumbs_up_1:

And thanks for posting all that information. :thumbs_up_1:
I think I will also buy that ER11 check and collets. I want to be able to make fine grooves with microcutters of 0,2mm to 0,5mm wide, but I can only find these with 4mm shafts, that don't fit in the standard MF70 collets...

Eberhard, I'm also very interested in small machinist jacks for this kind of work. But I would prefer to buy them instead of making them myself, so I can maximize my time actually working on the model (and I don't have any thread-cutting experience or equipment...). My first online searches yielded no viable results, but maybe you know of some sources?
As for attaching to the table: would simply clamping down not work?

Good to see you back on track EJ! The davit prototype is spectacular :cool_1: . i sense you're going to be unstoppable with your new weapon :big_grin:
Cheers,
SG

Indeed, the limited clamping capacity of the 'Micromot'-system can be nuisance. On the other hand, operating a 6 mm cutter on this small machine at 10000 rpm could bring some rather dangerous torque down onto the worktable, even if the motor only has 100 W. Perhaps that is the reason, why they limited the clamping diameter to 3.2 mm (= 1/8").

I was not aware that such aftermarket spindles were available ...

For such small cross-drilling operation some sort of dividing head with tailstock might be useful. Or an ER11 collet block that can be held in the vice. The collet would recenter the material in a repeatable way.

As you now have a mill (and had a lathe already) you could make yourself a miniature machinist's screw-jack to support the outboard end of the parts to be drilled.

I am using an old watchmaker's lathe bed with the dividing head and its tailstock and made this sort of jack I was talking about:

The idea of the jack could be adapted to the Proxxon, but one needs to find a way to attach it to the table - on mine I simply used a couple of neodynium magnets, but the Proxxon table being aluminium this obviously would not work.
