[hackerspaces] Tips on making passport stamps?

Re: low tech. 
If you have a Michaels craft store nearby, they have a make your own stamp kit. It has a carving tool with hemispheric blades so you can precisely remove the unwanted bits. Either use the rubber mat they sell or a pink pearl eraser. Once you've carved your inverse image, glue it to a block of wood and you have a stamp.

Subject: [hackerspaces] Tips on making passport stamps?

Hi,

Now that Mitch's passports are everywhere and our space has just voted
on a new logo, it's about time we made a stamp. But how to fabricate
one? I googled around for what other spaces had done and all the ones I
saw just did a design and sent it out to a commercial stamp manufacturer.
That doesn't seem very hackerspacey to me.

So, does anyone have tips to share on making your own? What materials
work best, just rubber (what sort?) or something else? We have a CNC
mill and a 40W CO2 laser cutter/engraver. Can you mill rubber without
just making a mess, can you laser engrave it deep enough to create a
usable stamp, if so what sort of settings did you need? Or is there a
way more low-tech process for spaces without these tools to use, that
still gets great results?

Tips welcome, then I will run some experiments and post our results.


Martin
