I’m going to throw another couple in there - I love an aluminium project.
As many might know I made my own aluminium bed (shipping from the US to UK wasn’t economical) - there are some designs floating around that I made with the help from @WillAdams who gave me the dimensions.
After knocking up my aluminium bed I needed some decent clamps that will hold down almost anything. I know you can buy some pretty decent ones in America, but making my own seemed like a fun project.
I wanted a quick release clamp that allowed me to work on thin wood for a sign project and others that would cater for some heavy duty aluminium milling.
First came the quick release wood clamps - you can get these handy clamps online and some come with bases - but they didn’t fit my table.
I came up with the below - Using quick release clamps bought on ebay
As you can see it’s a half H shape and the screw is at the back - these allow me to mount to my table using small M5 bolts. The clamp can then be adjusted to accommodate work from under 1mm all the way up to around 18mm by winding up/down the screws - note how the nuts look a bit gummy? Thats epoxy resin… As they use quick release clamps I can quickly mill wooden signage quickly and repeatably and the extensions of the H allow for flexibility on stock size.

The 2nd clamp is a more common style and designed for my heavy duty work. I can confirm these can handle a spindle going nuts and smashing into them - they have taken the occasional beating.
As you can see they are straight (around 10cm long), and have a slot and M5 tapped hole one side. The M5 hole allows you to position a leverage screw to accommodate almost any thickness of work - if you go over 50mm just swap to a longer bolt.
The main slot allows you yo put a M5 through it clamping down any work. These are really heavy duty and have served me well and if you use 4 of them nothing will move my stock…

As a heads up I used 8mm aluminium for both of these.
