      An Incentive to Start A Build Log - New Plan Set from the NRG   03/17/2018

      An Incentive for Starting a Build Log

      The NRG’s Generic East Coast Oyster Sharpie plan sets have been selling out – we had to reorder prints 2X already.

      BUT nobody has started a build log yet.  As an incentive we have decided to reward the first three (3) MSW / NRG members who purchase the plans and start and continue* actual build logs** from the plans. 

      The build logs should be started in the scratch built forum and labeled with Generic Sharpie – by “your ID”.  When we have six or more build logs up and running we will set up a group build area for the Generic Sharpie build logs.

      The winners will be able to pick any one of the prizes listed below:

      Free registration for one day at 2018 or 2019 NRG Conference                  ($145 value)

      Shop Notes 1 and 2 set                                                                         ($60 value)

      Nautical Research Journal – all content set                                              ($145 value)

      4 CD's or 1 flash drive         

      Continental Galley Washington Plan set                                                    ($65 value)

      1 year NRG membership or extension                                                      ($50 - $62 value)

      THE RULES

       

      *“Continue” means that multiple posts containing build log content must be made for a minimum of 30 days after the initial post.  Logs will be tracked by starting date and the first 3 that have continued for 30 days following their initial post will be declared the winners.

      **Note the words “actual build logs” – no fair showing a few pieces of wood and going no further just to win. 

       

      The NRG has a new set of plans available for purchase with a free 200+ page full-color monograph .  Check the NAUTICAL RESEARCH GUILD NEWS forum below for details.  This plan set is developed for the first time scratch builder with limited tools and experience.  All materials are standard strip stock available from hobby wood suppliers.  However, it is also a great project for the more experienced builder looking for a smaller project to take a break from the bigger builds.  Remember MSW Members who provide us their real name are considered members for the discounted price.  An email or call to the office before you order with your real name and MSW user name before you order is needed for the discount code.

Ropewalk (and serving machine)

Recommended Posts

Posted (edited)

Hi,

Last October a thread started by Derek (Worldway) in this section of the forum gave me the final nudge to get started on making my own ropewalk. 

I have previously built a serving machine and decided to try and use similar construction techniques such as using acrylic for the main structure and modified Lego gears for the mechanism.

Here are some pictures of this earlier project:

The Ropewalk:

 

Clear acrylic components were built up to make wheels and pulleys. Small holes around the rims aid alignment using the brass pins recovered from the first planking on my HMS Victory - I knew there would be a reason to keep them!

The Lego gears had their centers machined out and replaced by acrylic hubs. These have a square hole in the center through which 5/32" square brass tube is pushed. This tube, after a little filing, slides firmly into 6mm O/D brass tube axles which in turn fit into the ball races press fitted into the various support plates.

The track is in sections each about a meter long, which slot together.

I decided to try and use one motor to drive the end that twists the individual strands and a second one to twist these strands together.

The control box provides separate on/off switches, variable speed control and finally a switch to reverse the direction of rotation.

The motors were initially powered by batteries but I have now replaced these with a 6 volt power supply.

 

The 'Top' which guides the strands is mounted on an acrylic truck. This is fitted with the three stand top in the photo but there is also a four stand top.

These four strand gear plates are easily fitted in place of the three strand gear drive.

In use the strand twisting end is fixed to the track but the other end that twists these together to produce the final rope is free to slide along the track as the twisting process reduces the length of the rope. I'm still getting to grips with the best way to operate this device and need to experiment more with types of yarn, motor speeds etc. Early attempts are encouraging however..........

Cheers,

 

Graham.

About the NRG

If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.

The Guild is a non-profit educational organization whose mission is to provide support to our members in their efforts to raise the quality of their model shipcraft.

The Nautical Research Guild puts on ship modeling seminars, yearly conferences, and juried competitions. We publish books on ship modeling techniques as well as our world-renowned quarterly magazine, The Nautical Research Journal, whose pages are full of articles by master ship modelers who show you how they build those exquisite details on their models, and by maritime historians who show you what details to build.
