3D printing belaying pin

[modeller_masa]

Here is another small project.

 

The design of the belaying pin is based on this plan. It is an 8.5" long and 5/8" thick belaying pin.

The USS Essex used an approx. 20" long belaying pin, and the HMS Bounty used an 18" long one.

 

This is the most successful setting. I can build 2,000 pin handles per plate.

 

3D Printer : Phrozen Sonic mini 8K s

Setup : 0.020mm

Resin : Standard brown

Support tip : 0.70~0.60mm

 

The 1/72 scale of an 8 inch long belaying pin is not practical.

The 3.0mm belaying pin handle is the minimum size, with a little annoying assembly work.

 

Here is the result. I would say that 6.0mm long with a 2.80mm handle is the minimum size for my 3D printer. If the ship is USS Essex, the 10.7mm long belaying pin is 1/48 scale, and the 6.0mm pin is 1/85 scale.

The 3D printed belaying pin (handle) will be my priority choice. It is definitely better than my previous method, CA glued head.

That's a masterpiece work, Dziadeczek. A metal lathe was enlisted on my wish list a long time ago, but I can't buy it because there's no place to install the heavy machine.

 

I would say that my solution is dozens of times cheaper than commercial pins. Kit makers may include the 3D printed belaying pins instead of the large and thick wooden pins.

The metal tube doesn't extend very far up into the handle. Be careful putting any strain on the handle part of the pins. My experience with 3D resin printed objects are that they are very brittle and very fragile. It should be easy to break the handle off.
