But it seems to me there's little to do to make one of these - a cutaway in the clearing plate, a cutaway in the carriage, remove the outer housing around the sliders, cut the baseplate sides off. I mean, there's 37180 on eBay right now for a starting bid of $2100. But it's a $800 machine with a couple of bits cut away, nothing more. Has anyone attempted to make one of these on his own? I'd like one, and I have a donor machine available. But if there are pitfalls to avoid, I'd like to hear about them before I get my hacksaw out and start cutting! | ||

(it's the Curta from the red box).If you like to cut off a Curta by yourself you need some specific mechanical handcraft skills. And a milling machine with the fitting fixing tools. Then you disassemble your Curta (hoping you will be able to assemble it again later  ) - and now you will have ONE try for milling the parts. If this is given and you really like it... let's start! I would estimate about $800 for the complete professional work - so in total a "demo" Curta is worth about $1600 - not more. | ||

As long as the model is accurate, you can cut it up until your heart's content with risking a functional Curta. What's even better, is you can cut it up, and then render it to get a better idea of how it would look in a finished state. It's just a thought, though... | ||
