Thanks for all the advice. In short then, no hole is needed of printing a 2 1/2 " long logo, as per 'EmbossingDieCompany's post, just an acrylic base. I could drill a 1/2" hole and tap and die it for number stamping, but first I must find a machine shop which is not as easy as it sounds in the UK. I'm sure I will eventually track one down, but we're all about being a 'service industry' now, rather than a manufacturing industry today. Pretty sad really, but it's not like the states where everyone has a drill press and lathe facilities. I live in London with 10 million compacted people, but that's my choice I suppose. I'm sure I will find one eventually. About 'BiggunDoctors' suggestion for milling to a v-block - well, I would not know where to start, or how to use it, so I'm stick with finding someone with a drill press for now. i think a posted pic of this would help as I can't envisage how this would work to be honest.
'Silverwingit's suggestion of a hydraulic shop press is pretty cool too, as I'd never seen one before - only clicker presses and arbors. And yes, they are very reasonable, even for a 6 ton, so thanks for that. i've found I can get hole punch dies to fit my standard hand rivet press, from green grizzly too, so I've ordered that for the moment as it's easy and a cheap solution. At least for hole punching. However, i can see no way but to hand stamp an oblong punch, as the top is too wide to fit into even a bored arbor. Any tips on this would be welcome, and thanks for all the comments so far. I feel far better informed now, and more confident with which purchases to make too.
Oh, the Palmgren 61101 One Ton Arbor press comes pre-drilled for letter/number stamps, but it seems no one is impressed with the magnet holder as it reportedly breaks quite quickly. Still worth a mention though.
Hope this thread helps others out there as much as me...
