Hackspace Magazine issue 29! New Lasercut Rocketry tool on thingiverse.

So another month and another wonderful issue of Hackspace magazine is out and as ever I update this post to keep a track of all my articles. However this month I am breaking the norm and doing this post as I wanted to mention a tool I made as part of an article in this months on Dividing and Indexing. The tool is still a little work in progress, but it is a laser cut assembly that can scroll or self centre the 4 jaws or pillars and can hold a tube concentric to its central point of rotation. The centring assembly is using the same idea as a longworth chuck which I posted about years ago on here!

It can therefore hold tubes and other items and using the numbered gear wheel you can rotate and lock the held item in various positions. You can then use the vee grooved slot to lay a pen or pencil along and mark positions accurately in any division of 60 points around a circle. As such it's useful for rocketry it you wanted to mark a tube for 3, 4, 5, 6, 10, 12 fins etc. Do check out the article for more detail and the item itself is on thingiverse.
