Title: What bollard looks more realistic?
Post by: Jackets on April 03, 2009, 07:37:23 am

Hello all,


New to the site and RC boating, did the RC car/truck thing but is boring now.

I haven't picked a tug model yet as i will when i settle on what scale

Ok, to the main part of the question:

out of the 2 bollard styles in this drawing i made what seems more functional and realistic?
Pic scale is 32:1
154' x 52' x 10'
40* Rake and depressed cargo area

its an adaptation of a few i found


Thoughts? 

once figure out the bollards i can start the structural drawing/layout so they are built in as tough as they will get
Planning to build with 1/8' ply, and a glass coat.


Thanks
Jackets

Hi Jackets
Firstly most bollards are rounded from what Ive seen . The double one on the right seems OK.
Have a look at the model boat suppliers under fittings section for some designs if you want to build your own.
Brass ones always look good.....
If you plan to use them to tow you could use solid brass rod extended into the structure for extra support..

You would probably make the bollards according to the plan or the original so you would have the decision made for you.  If however you are making a generic model of something such as a barge then perhaps some pictures of similar typical barges would give you some guidance.

If you have nothing at all to go by then I would suggest a mixture of the two.  You might find the double ones at either end for towing, possibly one on each corner and the single ones along the side for tying up the barge to a quay.

This might give you some ideas:

I will go with BB on that one , as for your drawings  the square posts are normally seen on older barges used in the first part of the century as many were actually the wood ends (rib ends) with a piece of wood fitted to make a T .
You can make your own easily from lots of materials , i even have some spent shot gun cartriges to use in a future project , but for commercial bollards there are loads out there in different scales to chose from , the forum directory of traders will guide you and if your realy fussy then there are forum members that will make you some specific to your needs .

I went square as I have seen both, round and square and drawing the square ones was much easier


How much retention will they require to handle a full load, i had though about making them with brass and drilling and countersinking the centers and screwing them on but though they might tip or lean once they were pulled on when loaded.

May I ask Jackets, what programme/cad did you used to do the drawing on your post??

  If you look at the barge in the attached picture it may give you some assistance in doing bollards to haul a load. The tug is the Dumas "Brooklyn". The barge is about 8 feet long. The bollards (doubles) and are made of brass and sunk into the wood frame of the barge.
  I see you're in Ontario, where abouts?

Hey thanks for the pictures, indeed they help

In Gananoque, its just east of Kingston.

The Dumas: Brooklyn and Jersey City are 2 of the ones i am looking at. They are close in looks to the one i like the Midwest Liberty tug. but is in a larger scale. It reminds me of a tug i spent many a day on when i was smaller in public school. working for a dock install company locally. sadly they sold her and she is gone.
roughly i think it was 40 - 42' Length, 10 - 11' Beam,  4 - 4.5' Draft, it had  a 250hp 6 Cyl Cummings a 4:1 reduction and a 4 blade 42" by 24" prop in a cage
