With this thread I would like to open a discussion with regard to few modelling projects which I started in last months.
In this case I purchased three Atlas wood reefers models of 1900.
The model bodies are very good detailed. There are opening doors, ice hatches and a lot of more detail features. They have further a very fine lettering - although not all data are correctly.
Sorry for the quality of this picture. I should reduce the contrast so you will be able to see much better the details of the black frame.
However, on top okay but the quality of the under floor is miserable!
With what for type of frame is this model equipped? A centered steel frame without steel profiles and without the typically steel girder bars and there is not an only rivet to see. On the contrary this frame is equipped with queen posts and truss rods which are mounted on undefined crossing bars. Has a steel frame had ever possessed truss rods?
Or should be this a wood frame without side and center beams which is equipped with two U-shaped steel profiles where truss rods are bent to the under-body and end there? Turnbuckles which are looking like filled steel blocks?
No, I was not really lucky with this and my other two Atlas reefers.
So what could I do to improve and correct the model?
In detail - remove all details of the underframe and renew all them including a well looking wood frame! Furthermore to equip with Kadee´s arch bar trucks - or Andrews - and Kadee couplers no.58 and through improvement of a few smaller details.
First step: All original parts are removed and a cast center rip is filed down. I glued the original bolsters on the frame and I added four small curved styrene blocks which are responsible to avoid the typical swing of all American freight car models. Is there someone who knows a line where their models do not swing? One pair of white styrene blocks are spaced and lengthened so that the roller bearings of Kadee truck can slide on them. The other pair is filed a little bit shorter so that the second truck is free swivelling to all directions. Thereby I have got a very well working three point equalization like I have done to all my other models.
A first test with mounted Kadee couplers - coupler height is exact to Kadee ruling.
With ACC glue I added all the wood beams to a new wood frame that looks are very close to original wood frames. In a last step the outer end-parts must be added as they would hang a bit above the end of frame.
Next steps follow in a few days.
