Nice print, but is this not in the same league as 3d printing for food stuffs? As in it's not hygienic and not possible to sterilize? Those ridges are bacteria breeding grounds!

Same ol' faces... Almost has the feel of forums of yesteryear...

I'm on a rather old version of Solidworks, for various reasons, but had hoped for some improvement by now.

Although, I'm not surprised. Many, if not all of the 'premium' CAD and CAM software I have used have no multi-threading either.

I'm on a 7 year old laptop, i7-7500U CPU, 32gb RAM and run Solidworks in a VM as I'm also running Linux.

It handles parts fine, but struggles a bit with very large assemblies and rendering on surfaces. This I assume is the lack of dedicated GPU.

GPW3 anyone?

I've read about the anti-xray locks, but never got hold of one. A good find indeed!

It's the spline key that is missing. You can usually find some on ebay!

Interesting to see plastic wheels, all my locks have metal wheels. Bet that makes for an interesting open!

Great links! Love the patent drawings. Hadn't noticed the serrated edges of the wheels before. A very interesting lock!

I've only picked a few tubulars, most can be tensioned with almost anything as long as you can get it into the notch of the centre.

There's a couple of common diameters used so a couple of tensioners are handy.

Time to dig out my tubular locks again!
