Idiots guide to brass

[Neil WyattModerator @neilwyatt]

Or what about punching them out of brass plate…?

… brass tube 2mm OD and 0.3mm wall thickness.

… slices of said tube 0.5-1mm long.

Neil ,

Can we assume that punching this shape out of plate is another of your little jokes?

… especially given the tools at Izack's disposal.

Izack does not have a lathe

I'm sure you've got me wired for sound or video as well as you keep saying what I'm thinking. 😜. You're right I've not got a lathe but I do have a drill and may be able to adapt that idea but a lot slower. But thanks for the comments as I'm never to sure if people are serious or joking when they offer this sort of techno strong advice.👍

Not at all, I'm assuming these a re dummy pulleys so the I/D of the brass disc isn't critical, in fact it might be easier to fit a disc than a ring, I assume the choice of a tube rather than rod is just to make cutting easier?

From earlier posts it would seem the smooth surface of the tube was desirable for the rigging to run against, a punched out disc or washer would have quite a rough surface. Tube was just easier than solid rod.

Hi.

The choice of tube was pure mathematics. I had some tube i didnt have anything else ☺

None of the dimentions are crutial. What im after is a simple way of repeatedly and easy method of cutting a load of rings. Ideally something i can pick up do a dozen or so then do something else. Its just the repation and force required thats the big issue. The repatition i cant avoid but i was hopeful there was a simple force free or less than i was using. The other benefit of using tube is the fact that the surface is smooth. Then even if the wheel fails to turn the slick surface allows for a smooth slide. And if i needed i can evev add a curve to the outer surface by putting the rings between two centre punches. AKA as masonry nails ground to a flat point. This would only be where the wheel is truley visable.

One other option i do have is copper capillary tube 2mm OD x 1mm ID would this be eaisier to cut?

Hi your right about the surface and i had the ube and had no rod. Its the method i was hopeful of improving but effort and safety.

With a bit of luck i may have solved the issue another way as ive ordered some jewelry spacer beads 1.5mm x 1.5mm. Unfortuntly they are from china. So not only do i have to wait while they crawl here. Ive no idea of quality. Or even whe=at they are made of. I had one set of brass seed beads come that i was wanting to flaten for another project only to find out they were made of glass. Not easy keeping the dust from disapearing every time you hit them with a hammer 😉

Just a thought- would plastic tube do the job? Lots of sizes and materials. Easy to cut.

I'd have thought that all thats needed is a plain pin(probably brass) through a little wooden block, no need for anything resembling a pulley.

It depends on the scale of course but most model makers make do with simple wooden blocks with a couple of holes in it. For some reason the OP doesn't want to do this. All the models I've seen made the conventional way look fine to me and there are plenty of tutorials on the subject on the relevant websites. One of the best is the one I posted earlier.

There are also books that deal specifically with rigging of period ships.
