Humber Maintenance Barge
« on: January 07, 2014, 06:38:55 PM »

Twelve months ago I was given a ‘Mountfleet’ kit of a lighter and started a blog in a previous post under Tugs & Towing as I thought it would be good to give it a personal touch and requested lots of information to help me decide on the type of craft to build.

After much deliberation I decided to adapt the kit to produce a maintenance barge giving me lots of opportunities to include some toys to make the model look good.

This is my first build which includes a GRP moulded hull, in the past all of my builds have been with wooden hulls so I am on unfamiliar ground. After lots of hours reading articles referring to previous builds and particularly Humber barges decided that I should chop off the stern of the lighter to enable me to fit rudder and prop and shorten it as a carrying barge would be longer than a maintenance barge.   

My thanks to Howard for pointing me in the direction of Malcolm Slaters ‘Humberside Working Barges’ and the waterways museum in Goole also thanks to lighterman, we are out of R&D and the steel is ordered.

Anyway a start has been made with a section carefully cut out of the GRP moulded hull, moulding lines helped achieve a relatively neat cut and the section yet to be removed for the rudder and prop marked out. Some trials to be made with various adhesives to decide on the best for the job, very little filler will be needed and maybe  a couple of reinforcing pieces added to the inside of the hull.

Progress is maybe too optimistic a word. I now have a stern section of the barge with a huge orifice for the prop and rudder. It was easy to cut out not sure how to fill it. I built a beautiful Patrick and Blunt model Tug some years ago using the sandwich balsa method. Maybe have to use that method to achieve a reasonable 'swim' on the barge stern. Alternatively the bin men come on Tuesday, watch this space. Chris G

Hi Chris
When i converted my Thames lighter i cut out a section then used a piece of rainwater pipe to form the tunnel for the prop and rudder, nice and easy to work.

Hi Dave
It would seem there are two early birds out and about.
Good idea and I will check it out although the hole I have got after trimming rough edges is 5 1/4" or 130 mm in new money.
I will let you know how I get on Chris G

Hello I seem to have lost the reference you sent me to check for pictures, only have the first part of your post, or am I going mad?

With which you paste the rainwater PVC pipe on the hull fiber?
How do you seal

Hi Chris
No you're not going mad i had to edit the post as the 2 pictures i had posted did not show the tunnel only the finished craft. If the hole is that big you could probably use drainage pipe maybe a friendly builder has an off cut. http://www.modelboatmayhem.co.uk/forum/index.php/topic,3407.0.html


Hallo Gazou
I went over the top in fixing the pipe i roughed up the outer surface then spot fixed using p 38 body filler before reinforcing using glassfibre, when set i then cut the pipe to the shape of the hull.
I've posted the link to the photos i can probably get some of the boat later if it helps.

Hi Gazou
Yes roughen up the pipe first then use the method i mentioned, i've been sailing the lighter for nearly seven years now and never a leak.

Dave the lighter looks a treat, I am glad to know I was not imagining things earlier.

As I have no fossils I plan to load mine with a JCB and some gravel but that is a long way off.

Thanks Chris G

Chris is this to be a motor barge or a sailing barge?

Scratch that, just read your last post doh! Motor barge obviously.

Hello
Traumatic time figuring how to fill the hole !!!!!! the balsa method was a failure and a costly one at that, I then after 24 hours thinking about it resorted to the good old GRP.
The two halves of the hull are now joined using glass and webbing, strong as original lay up. The hole is filled and with enough space to have both the prop (up to 50mm) and rudder protected by the stern overhang of the vessel. This I wanted to achieve as I did not want either hanging below the hull or aft of the hull.
I am chuffed, the inside looks ugly but that will be covered by deck and superstructure, the rest as good as I can make it.
More next week GW Chris G

It is really nice to see something different, and smaller working boats always look great to me. Perhaps because as a kid, these are kinds of boats I would see working on the rivers. They always seemed more accessible than the much larger ships. Perhaps because of the films of people owning and working boats I used to see.

Trying to achieve good proportions for the vessel.  {:-{
The 'lump' at the moment after the original has been chopped about is 700mm length 220mm beam 90mm height to gunwale.
The length of the hold is determined by the build and proportions from 'Humberside Working Barges', the width of the hold is wrong at 55mm each side 45% of beam and I intend to reduce it by 25mm each side which will leave enough room for a 1/32 scale man to comfortably walk the side decks.
Another stage of the build which is difficult to scale and build is the wheelhouse and accommodation. The photo's show some of my expensive scrap balsa cut to give some indication of size and height, but is it right?  {-) The 1/32 scale man looks right against the balsa.
I have fitted a fore and aft bulkhead not in the original but what the hell I had a bit of gash ply and it will tidy up the hold.
I have fitted prop tube and rudder but will describe its fitting when it looks finished.
Still thoroughly enjoying the build and look forward to any comments, well maybe! Chris G

Sorry
Should read each side deck 55mm which equates to about 50% of beam. Chris G

Cereal packet card is a reasonable alternative to the Balsa (keeps the costs down) and should still help with "eye-balling" the results prior to committing the Balsa to the sawblade. O0
 
Getting along well there Chris :-))

Chris from the pics above it looks like your deck is flat? From memory I think they had a radius from centre line to outer hull with a coaming of sorts around the hold. I remember being on the docks as a kid and almost coming to grief on one, it was offloading linseed, I leaned over the coaming to grab a handful and overbalanced. Off course the linseed being very very oily it would not support me, Hands just sank into it rapidly followed by me. Fortunately a bargeman grabbed me by the collar and pulled me back from what could have be a tragic accident.
