Plan reading

[Anthony AtkinsonParticipant @anthonyatkinson85393]

hi was looking at the latest free plan but I am quite new to modelling straight from a plan and was wondering if anybody could help with any tips on reading plans particular in respect to this section

Many thanks

If you click on this link it will take you to another model boat forum. You should look specifically for the board called Masterclasses. **LINK**

I'm not exactly sure what part of reading plans you are having problems with but the building of models from plans is very well covered by many of the threads here. I can particularly recommend anything written by MB Forum member 'Bluebird' aka John Elsy. His blogs are better than the best kit instructions you'll find anywhere.

Thanks for you comments Dave, I think I have figured it out I think my confusion was the T but I suspect that's transom but most of all why having some sections labelled say 1 1/2 why not just add more full numbered piecies and why start with number one at the back not the more logical at the front anyway thanks again for your comments.

I don't know which plan you are having a problem with but there are certain conventions which apply to drawing scale plans of full-size vessels. One says that if each half of a hull is identical then it's a waste of paper drawing full sections. Numbering frames does not seem to have a convention although most of the drawings I have – and all of the ones I draw myself – start with #1 at the bow.
Incidentally I've never found out why model aircraft plans are usually drawn with the nose to the left while model boat plans have the bow to the right.
I guess it's all part of life's rich tapestry…

Can you copy or take a digital photo of the drawing section that is giving you problems?

If you can and then post the image onto this thread we will be able to answer your questions.

DM the cheque is in the post

 

With regard to plans – are they the free plans from April 2017 Model Boats for the Classic 1950s Sputnik Trawler? drawn by James A Pottinger. If so, the frames are read off as this:

 

looking from the stern of the vessel; first frame T is transom;

the half frame is the central line of your rudder post –

frame 1 gives the position of approx. positions of the propeller boss

and they work upwards towards the bow

 

Nice plans, could be a future build – but – if you go over to the Mayhem Forum and seek out the build for the Trawler Sea Lady – Angel Emial- it has a similar sort of setup with the flat stern.

Regarding items such as Frames and Bulkheads being drawn showing only half of the shape. This convention is used to save drawing time (especially before the introduction of CAD) and also to emphasise that the item is symmetrical about the centre-line. The same or similar convention is normally used for handed parts i.e. where an item has a L/H and R/H variant, only one hand is drawn, but with a note to confirm that the opposite hand is also required.
