Windows. No good just looking at em! time to do it.


So I drilled out a fair bit of material with my step drill before turning to the Dremmel



They'll be finished off with a round file when I make the frames



I've removed more matter from the top shelf frame to improve visibility



Unfortunately my cheap copy dremmel drum sanding mandrels are tom tit. So no more until I get some genuine ones  :((
I've also soldered 4mm brass washers to the front mast legs. So no more levelling up.










Made the front below deck access hatch (artistic licence  {-) )





I'm going to York MBC open day tomorrow  :-))

Two coats of primer here over sanding sealer. Final coats will definitely look like steel  :-))

Thanks John  :-))
I was just typing this as you posted. I just had a look back at page one of the thread. Little did I know what I was in for {-)

So I started in March and progress has been a rollercoaster and I've come to understand that this is normal for the average builder.
Sometimes we get loads done and put many hurdles behind us and then we hit the doldrums of life getting in the way or a technical obstacle requiring help.
This last three weeks has been great and I think I finally have a grip on practical completion this year but with many additions or tweaks to keep me going next year.
I'm not sure yet that I'll light her up as I still live with the fact she can never be perfect so I'm drawn to starting the Maltby next and giving it all 8)

Some times problems, sometimes money, sometimes enthusiasm, sometimes a stupid mistake, they all add time to a project  O0 The window cutouts look very straight, I salute your accuracy. Regards the hatch, working vessels as well as military ones get changed and altered all the time, so a little artistic lisence isn't an evil.

 :-)) O0 Yes I made mistakes a plenty. When the enthusiasm is working there's just no stopping.


Re straight lines. I was on my knees with dremmel flexi drive and dust mask on.


I made the mistake of putting the wheel house roof on the wrong way around and I didn't notice until I came to put the mast on. A good job I wasn't gluing it on  %%  as it fits perfect either way  {-)

An hour per evening is my limit on work days now  :((


First brass window frame fitted.



The funnels didn't have enough height or taper at the base by the time I'd got them ground off so they were perpendicular.
So I've built them up with ply, shaped as necessary and resin coated before final sanding. The MMM supplied castings are tapered on four sides but the Portgarth is only tapered on two of those.

Photos of todays effort.
All deckhouse windows done and masking up so I could spray sanding sealer on the rest of the sides and still be able to glue doors in place later.

The concept of using brass strip over plasticard is a great idea :-))....and produces an extremely tidy frame result

However just at a rough guess  %) ...you have about 72 window corner bends to produce

Considering they all have the same corner radius, this would nearly warrant producing a small jig...with one fixed circular ring and one circular ring at an adjustable distance away ;D

The radii of the smaller windows (wheelhouse roof) is smaller when Iíve finished them with a file and is equal to a pair of 6Ē pliers in my right hand and brass strip in my left  {-)

Great progress today or so it feels
Just some very minor filling for perfection once the primer is hard.
Masking tape over all attachment points and Iím going to attach the forward deck hatch to the deckhouse so it lifts off together

Re: MMM Portgarth build......... brass tube cutting
« Reply #695 on: September 30, 2017, 08:21:58 PM »

I've been using brass tube for the hinges and to make sure they are all the same pin length I made the jig.
I picked up this tip on you tube to cut tube without crushing.
Just score heavily with a blade while rotating the brass then it will snap off clean with pliers placed near the score.

Getting a bit more adventurous Iíve started the RIB frame.
This is one of two main legs that everything emanates from.
A little oversized but wonít be noticeable with the smaller metals off it later the idea is that Iím aralditing two stub sleeves into the deck so the whole frame can be easily fitted and removed.
