Hi Michael, thank you for your comments. I only ever part off on manual feed so doing it slowly was fairly easy. I find soft solder is remarkably strong for jobs of this type, it rarely seems to come apart during machining. I did however make sure the parting tool (which was only .025" wide) was very sharp. Pat - I look at many models on this site with admiration, everyone seems to have something that they excel at. And so to cutting the roof end mouldings. I checked the curvature against a set of radius templates that I downloaded from the web. The radius required turned out to be 22". I improvised a jig to cut this radius. I started by cutting a piece of wood to be a snug fit in the end slot of the mill table. Into this I inserted a steel peg. A piece of MDF was then cut, one end with a hole to fit over the pivot pin and the other end with a "L" section cross piece onto which the mahogany stock was mounted. The distance between the pin and the centre of the cross piece was 22". The mahogany was mounted with double sided tape and the curved beam was cut by progressively passing it backwards and forwards while feeding the end mill down. It didn't take long and the results were fine. I used the previously made scraper to form the profile before glueing the ends to the roof. The corners were then manually finished so the moulding shape wrapped around the corner. The cut out for the hatch was then removed and the hatch runners and side detail was then commenced. The hatch planking was built on the roof to get the correct curvature. Sellotape was laid on the roof to facilitate this operation.

PoulD - Early on I did toy with putting LED's inside the hull but I knew that after the first few months I would never turn them on again. Thank you for your kind comments about my craftsmanship, I keep trying but have a lot of room for improvement.

Druxey, Steve, John - thank you for the compliments, they keep me warm as the workshop starts to cool - only 9 weeks to Christmas.

Keith - You are right to suggest it won't be possible to see them so it is somewhat pointless....................... but of course I will.

Richard, might work but at 0.2" thick I think it would have some memory and would flex back to a larger curve. I could over bend but this might be a bit hit and miss. I have worked out a plan to machine the planks to the desired radius. I'll try it some time this week and report on my success or failure later this week.

Nicely done. -
Self-made small horizontal milling machine

Pretty amazing. I'm in awe. -
Allan - basically yes - I'm using the mill which of course has a x,y table and of course I also have z axis control on the grinding wheel. All very controllable. Eberhard - yes I believe the deckhouse is vented via the frieze and mushroom vents. My guess is that the vents are brass but the crew seem to have run out of brass polish. I will make them from polished brass.

Well that's another week gone by with only modest progress. Much of the country is experiencing high Covid restrictions but our area is only on the lowest level of alert. Unfortunately the children and grandchild are still in London where more significant restrictions apply which means that we are again isolated from them. You would think this would be good for productivity but alas this is not the case. Mark, Pat, Keith, Richard and Gary, thank you for tearing yourselves away from your builds to leave supportive comments, they are much appreciated. Also thanks to everyone for all the likes and visits. The last week has been directed towards roofing, the roof of the deckhouse actually. I wanted to get the internal and external features reasonably representing the real thing. I include a couple of images as a reminder of what I am roughly aiming at. Rather than try and build onto the fragile deckhouse walls I decided to create a much more substantial building jig. I then cut the frieze planks that fit internally above the side windows. The two were cut together joined by double sided tape. There frieze planks were cut from 1/32" ply and to prevent splintering were drilled while attached to a backing plank. The friezes sits in a slot in the jig and to prevent the roof sticking to the jig it is covered where necessary with sellotape. The cross beams were then installed and glued to the frieze at each end, The top of the jig is sloped to match the deckhouse sides but the beams are mounted vertically, so lie at a small angle to the frieze. The cross beams were installed extra wide and then sanded back to match the curved profiles of the front and rear faces of the deckhouse. The ceiling of the deckhouse is painted white but has a planked appearance. This was crated by slotting a piece of 1/32" ply on the Byrnes saw using a .020" width slitting saw. On the reverse side of the ply the roof was planked in the same manner as the deck. This was then glued to the roof frame on the jig. Once dry the roof was removed from the jig and additional beam detail was added. The edges were then trimmed. Before the roof was placed back on the jig and sanded to a smooth curved finish. The roof edge is made from a substantial piece of profiled mahogany and I wanted the profile to be reasonably representative. The sketch shows the profile which is 0.2" high. To create the profile I made myself a scraper from an old boxcutter blade. Making the long edge planks was then a fairly straightforward scraping job. Once made these were glued to the roof. I now have to make the equivalent pieces for the front and rear of the roof but these will be curved and will therefore be a bit trickier.

More than I would have guessed Eberhard. She is a fascinating little vessel. Logically she would have been very vulnerable to fire from smaller quick firing guns. I guess her rate of fire was quite low and presume her accuracy was somewhat problematic. The crew must have been quite nervous between shots.
-
Nicely done with the shells Eberhard. Do you know how many shells the magazine held? With such a large gun mounted on a small hull I am assuming that the magazine capacity was very limited.

Allan, I did wonder whether it was to facilitate wheelchair access - very commendable. My sailing days are behind me but I do know that the tack that the boat is on is fairy important when choosing the head to occupy (port or starboard). Presumably the crew won't mind changing tacks to assist sailors with limited mobility.

She looks an interesting vessel Per. I will be interested to see how she progresses. -
impressive and for me very educational. Thank you.

Very clean work Allan. I’m finding this vessel really interesting. I’m sort of assuming a vessel of this size has fairly extensive below deck spaces and this is prompting me to wonder why on earth the deck cabin space is being compromised to facilitate the fitting of a toilet pan and sink ( particularly as they eliminate the possibility of forward views from the cabin). Instruments, chart tables, gin cupboards all seem better candidates for deckhouse space. Does anyone have any insights into this novel prioritisation of facilities?

Really not sure how you could see that Level detail Keith. It is actually a real ships registration certificate, although not for Germania.

I’ll be Looking forward to winter Michael. As with a lot of the world it is looking like I will be spending a lot of time indoors.

An interesting and elegant little ship which I will follow with interest. In so far as filling out the frame is concerned I have found that laying up multiple layers of thinly cut planks around the edge of the frame works well.

About the NRG
If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.
The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.
The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
