Frodo Report post Posted September 8, 2019 I have an idea, wanna kick it around and see if we can figure it out? a pvc pipe, open back bangle, covered in leather with a strap to hold a watch. Quote Share this post Link to post Share on other sites

RockyAussie Report post Posted September 8, 2019 Just in case it helps some. As you would have found out I think it can be difficult to sand around the edges whilst its round. What I found in the end to be quicker and to get the more oval wrist shape is to cut the pipe into lengths to get the width then cut into the side (65mm pvc vent pipe I think) I then procede to heat them up with a hot air gun and flatten them right out straight and allow them to cool of under a flat slab. They are then easy to shape and chamfer etc. I found a piece of steel pipe and based into an oval shape and from there I heat the pvc pipe again and bring it into shape. After that I attach foam and leather and lining etc. Now its easier to just 3d print them in pla. I have not done the watch band as such but here is the open back bangle shape. I think the weight of the watch may just beat you on this but you'll never know lessen ya try Might be able to mix the ideas a bit Quote Share this post Link to post Share on other sites

Or would that still be too expensive? Quote Share this post Link to post Share on other sites

I do have a plastic extruder that took a LOT of work time to lathe up the moulds for these bangles and they are quicker to do in time but maybe not in the labour cost. BTW if you get into the 3d print stuff the hangers holding the bangles in the third picture are something I came up with to make it easier to get an individual bangle or bag on and off without taking off a whole lot. Here you can see if you want to get to a bag on the inside you have to remove all the outer ones first. I had to come up with a something to put in a shop so this was my answer.

robs456 Report post Posted September 8, 2019 Good stuff, but for us without 3D printers I think maybe thermoplastics could work. I've wanted to get into 3D printing for a while though so who knows what the future brings... Quote Share this post Link to post Share on other sites

Frodo Report post Posted October 7, 2019 (edited) I pondered this idea for a few days, then came up with an idea I took a piece of copper pipe and beat it flat, then annealed it Then I beat it into the shape i wanted then i drilled a couple of holes, wrapped it in leather added a strap to hold the watch...I have to stop here. I need a longer snap here is the finished watch band less the longer snap Edited October 7, 2019 by Frodo Quote Share this post Link to post Share on other sites
wizard of tragacanth Report post Posted October 7, 2019 (edited) So, you need a snap with a longer post that will pass through thicker stock? What are you using now? Are they Line 24 snaps? Tandy Line 24 snaps have a 5/16" post. Is that enough? https://www.tandyleather.com/en/search/?sSearch=line 24 snaps nick Edited October 7, 2019 by wizard of tragacanth Quote Share this post Link to post Share on other sites
