Progress Mark 2 - Posted: 21st Jun 2017
Hello all,

So I've managed to get back to somewhere near where I was last time. The frame work is of a slightly thicker Ply (1/4") The Keel is straight, frames are all 100% level and I've now used balsa block for the Bow and Stern to give the planking a bit more support and to assist in getting a better shape at both ends.

Fingers crossed I will have the hull build in the next few weeks, I can then get on with Sanding and filling before applying fiberglass and Resin to make the hull solid.

Uploaded a few photos to show where I'm at.

Good luck with your builds.

Dave.

Looks much better supported and good progress being made.

Er slight Problem - Posted: 18th May 2017
Hello all,

I've had to start the hull from scratch. I went away for a week, I came back to see the hull bent in all different shapes, no amount of sanding or filling would rectify that so I've had to start again.

This time it's out of any direct sunlight!

Regards

Dave

Hi
When you started the build I saw that you had a good strong flat board and had supported the keel in several places. It looked as though it was all going well until you started to skin the hull with very heavy balsa(?).
When applying skins the hull does need to be supported at all times and skins applied equally to both sides at the same time.
Wood has a nasty habit of shrinking as it dries, and doing equal planking on both sides helps compensate.
When we built the Titanic and Olympic the hulls were built upside down and remained on the build board until all planking was complete. We used 4mm balsa sheets. and covered inside and out with fibreglass matting and cloth.
To use this method you need to extend each former so that the hull is level to the board with a gap at the bottom when you have finished. Couple of pics attached may help explain.
Good luck with the rebuild

Hello Dave,

Thank you for the advice, have you written a book as you are the oracle :)

I was using 4mm balsa for the walls but I think when applying I've not had the frames back in a solid / secure support? Lesson learnt now, the frame is staying in their secure mounts until I am satisfied it's not warping.

One thing I did notice with you models of Titanic and Olympic was the lack of stringers, I take it the frames were thick enough and the Balsa thin you did not need any lateral support?

Again thank you for your advice on this one.

Regards

Dave

Hi Dave
I don't think I am that but we did a build blog and the pics are from that.
Yes you do need to support the frames and keel and plank equally on each side and wait until the glue has dried before removing.
No stringers needed as 1/4 ply frames screwed to the baseboard. Once planked the inside was fibreglassed and the outside covered in glass cloth so the structure was very light and robust for a 9' model.
Hope you manage to get your hull made on the next attempt.

Build Update - Posted: 20th Mar 2017
Hello all,

Hope you are well? It's taken a while to get to where I am but I can start to see some real progress. I've managed to get the main superstructure complete, they are at a stage where they could be connected to the deck if it was ready.

The Hull is now covered in a layer of Balsa, it does now need a lot of rubbing down so I can then look at applying a layer of fiberglass. I've not ordered this yet but I have seen it advertised at Cornwall Model Boats. If anyone has any suggestions on how to fiberglass I'm happy to hear any advise as this will be my 1st time.

Good luck with your builds

Regards

Dave

Bridge Build - Posted: 3rd Feb 2017
Hello all,

I've been busy with the Bridge build, this has proved a little tricky as the forward structure is at a slight angle when not on the ship. I've used a combination of 1/8 ply and 0.75mm plastic sheet. I needed the ply in this section as this will be where I will have hull access for batteries and needed the strength. The walls of the upper structure are plastic sheet which I think have come out well. There is still more to add (look out wings at the rear of the bridge need walls etc) I can the start to connect this to the decking before adding finer details.

Coming on slowly is the hull, I will spend a bit more time here over the coming weeks to get it ready for sanding and then fibreglass coating.

Good luck with your builds.

Dave

Progress on Build - Posted: 11th Jan 2017
Hello all,

I've made a start on the Superstructure, they are basic ply with blocking to support. I've split the sections into 3 as I want to have the middle superstructure secured to the decking but have the forward and rear sections removable to allow access to the motors etc.

I've also made a start on the planking for the hull, this is balsa which I will look to cover in fiber glass once it is ready.

slow progress and I'll update more when I can.

Good luck with your builds.

Dave

Finished Sections and Top Stringer - Posted: 19th Dec 2016
Hello all,

I've finished leveling the Sections and added the top stringer to firm up the structure. I need to now make sure the sections are running in line, I've taken a tip from a good build article on Warship Models Underway: (http://www.wmunderway.8m.com/cont/hullcont/hullcont.htm)

I'll use a single baton to run down the sides of the ship to either smooth off or add to each section until I'm happy that when I add the hull sides it will be 99% straight.

I've also realized how small this ship will be in 1/96 and it may have been better in 1/48, so will need to start thinking about maybe using one Engine and looking to create a gearbox that allows two shaft output? If anyone has any suggestions please let me know.

Regards

Dave

Looking good. 👍 Same construction method I used for my H Class destroyer. Appreciate the size problem, typical length to beam ratio of destroyers ca 9to1. Gives speed but affects stability. Where did I read quotes like "she rolls on wet grass"!
I chose 1:72 for Hotspur giving 136x12cm to play with. Don't despair; I squeezed in 2x500 brushed plus switching for lights, 2 sound boards, loud speaker, smoke generator and rotation for radar and main guns. Sure you can get 2x385 motors, or small brushless in 😉 Keep the top weight down though, or with the Buckley's 8.4 to 1 length to beam ratio you might have a near heart attack on the first fast turn, like I did with Hotspur 🤔
Keep up the good work, look forward to the video ....
Cheers Doug 😎

Hello Doug,

Apologies for not responding but thank you for the tips in your response. I'll note them when it comes to the Motor install and see what else I can squeeze in from a functionality point.

Best regards

Dave

Captain Class Frigate - HMS Curzon K513 - Posted: 7th Dec 2016
Hello,

This is my second attempt at this model, I tried this many years ago but had to admit defeat as I did not have the time or patience as a 20 something. Anyway, older wiser and with a lot of lessons learnt I am giving this another go.

She was originally a Buckley Class DE from the US and transferred under the Lease Lend scheme to the RN in 1943. This was my Granddads ship in the war so I have a connection to her and have always wanted to have this as part of my fleet.

I've uploaded an image of the plans I have from the Model Dockyard (US Buckley DE) and will modify it to fit the photo I've also attached. The final picture is my start on the keel and forward sections tacked in place.

I'll upload more when there is progress.

Good luck with your builds.

Dave

Good luck with your build Dave. I'm an old newbie so will watch and learn, cheers, Ian. 👍

Thank you Ian, hope I can pass on a few gems??
