Glen Rosa 1893

[oapanglais]

Hello Everybody
I am new on Puddleducks. My current project, a Thames sailing barge is nearly finished and I am collecting info for Glen Rosa. It will be my first paddler so I will be asking for help occasionally. Can any Glen Rosa builders give me prior warning of problems? I have got the Phil Thomas plans and I have printed off the John F Gray build report from the Model Boats website. I will use the Models by Design hull. I want to build my own paddle wheels but the plans don't show any information on them. I have a copy of Model Boats March 1980 which has an article and reduced (just readable) drawing of the wheels for the Director class tug. I intend to use this as a starting point. The Glasgow Transport Museum photos in the gallery show the beautiful model of Glen Sannox with 8 bladed outside feathering wheels. As they were both built by J&G Thompson for the Glasgow and South Western Railway I will assume the Glen Rosa wheels were 8 bladed outside feathering unless anyone can advise otherwise.

I realise I have fouled up, the subject should have been Glen Rosa 1893. I don't know how to change it.

Title change for you

Thanks for that PeeWee

Hi Brian,
I have seen the Glen Rosa sail on my local pond as built in the Model Boats mag.
One word of caution... keep her light ,,,, that might mean deviating from the model boats Magazine right up.
Why do i say that ... well the model in question now sails with a keel .. you decide.
Regards,
Kim

Hi Kim
Thanks for that. I had already read about the keel on this website, and am thinking about ways to reduce topweight to try and avoid using a keel. Both the drawing which was from builder's plans, and the Model Boats mag model deviate from photos. Some photos show a new bridge in front of the funnel which was apparently fitted in 1926. I am going pre 1926.

hi Brian,

I was looking at the original article in  model shipwright mags 1975 and 76, for the Albion hull, by Brian King, who moulded the hull. It seemed to perform fine, keeping weight down, although he did have choking paddle boxes at first because the vents were blocked, and non feathering wheels. He mentions the final displacement of 11.5lb

The model in the "model boats" mag is adapted for oversize graupner wheels, ie the saloon sides/boxes are higher...maybe that affected that model.

Hello Clark

Thanks for your comments, very helpful. I am sorry I have taken so long to reply. The hull has just arrived so I will try a flotation test. I have made some of the easier paddle wheel parts, but I have gone back to finishing the Thames sailing barge after working out how to solve some problems.                  Brian

Are these of interest?  Note coal hole in group photo.

Interesting pics, Geoff, but a different Glen Rosa.

Silly Geoffrey  of course it is the Glen Rosa 1877.

Hello Geoff and Clark
The 1877 Glen Rosa kept showing up when I was searching the net for photos.

I am still slogging away making parts to finish my Thames barge so no more progress on Glen Rosa yet. My bath is too short for the hull and so I have had to wait for the rain to stop, to do the flotation test on a swimming pool. Yes we have had rain here in France as well though not as bad as yours. I marked the waterline down from the deck and not up from the base of the hull, because the hull is 5/8" deeper than scale. The results of the test were hull 2.257lbs, ballast 9.017lbs and so displacement 11.274lbs which is very close to the 11.5lbs you mentioned Clark. The My Hobby Store website where I bought the plan talks about 8lbs displacement at scale draught which is misleading because of the non-scale draught. I bought the plan without realising that Models by Design would send me a plan with the hull.  According to paddlesteamers.info the prototype was 306 gross tons and this works out at 6.20 lbs at 1:48 scale. That extra 5/8" is going to be very useful.

I am going to make my paddlewheels to fit the the paddleboxes as drawn. Photos of Albion and Glen Rosa show extra accomodation on the forward part of the sponsons which doesn't appear on the plan. Presumably a change requested during construction maybe for toilets. Also on the plan view there is a mysterious "bulkhead" shown in line with the front edge of the funnel, which isn't shown on the side elevation. 

Your photo is new to me and shows the light grey colour scheme and pre 1926 bridge arrangement that I want to model. At 37.77kB the file is too small to enlarge, could you pm me a larger file if you have one? I would be most grateful.

Thanks for your interest          Brian

Glen Rosa, the GSWR one, had a grey hull and red, black-topped funnel until the railway grouping in 1923, the in 1923 a grey hull and "tartan lum", yellow funnel with red band and black top, in 1924 a black hull and still a tricolor funnel, but with a thinner red band, and from 1925 until scrapping in 1938 a standard CSP livery of yellow black-topped funnel.
Her sister Minerva was very similar. The bridge was moved forward of the funnel after she was reboilered in 1926
