Hello /diy/,

I need to cut a fuckton of paper cards just like in pic related. The dimensions are in milimeters, which means that they are ridiculously small.

I want to have something reliable and not eyeball them all the time, as I need more than a thousand of them from each size. Tried a paper cutting die company, but in my country, the price is prohibitive.

Pls help.

Lay out a zillion on a page and use a cricut.

Walmart has paper cutters for about $25 iirc.
Clamp a strait edge on it to use for a stop to get consistancy

OP here, I have one of these, but the thickness of the blade is greater than the width of the card, so there is no way I can make a guide for this. Unless I modify the shearing arm, but I am not sure how.

>>1465954

Apparently they do not sell this in my country, and to import would make it go for around a thousand dollars. I don't have this much money to spend on this, sadly.

Get a steel rule die made ($60 to $90 from http://steel-rule-dies.com/)), buy an arbor press ($80), and a slab or self-healing mat, and a very flat piece of steel or aluminum to use as a backing plate for the custom die. You can punch them out pretty quickly. I use one for cutting foam (that requires a hydraulic press), and one for cutting adhesive-backed silicone.

make your own die.

Put the guide on the other side
I had this set up with nuts locked together for several preset sizes.

>>1466037

This is probably what I will do if I can’t make anything, but I would prefer to do something myself instead of buying.

>>1466053

Sorry, I think I am too dumb. This looks promissing, but can you elaborate a little more? I got the idea of the pre setups with the nuts, but where does this thing fit on a paper guillotine?

The blade is at the top of the pic. The aluminum angle "stop" could go right up to the blade if the safety guard were removed, which you'd have to do for 2mm.
The alum. angle on the bottom of pic is bolted to the cutter table and doesn't move

And the paper doesn’t swing? I am trying to do something like this, but the paper always slide and ruin it, because of the super small resting area.

Yea, I remember now, that was a problem.
It's been a couple years since I used it.
For narrow pieces I set the stop, cut the narrow strip off of a stack of bigger pieces, then moved the stop to repete

This is the problem I am having now. I have to cut more than a thousand of each, so I can’t be adjusting everytime.

whats your budget? you aren't going to get fast / cheap / good. So you either put in a bunch of labor yourself, or you pay more for it.

I am an entomologist (in fact a engineer misplaced on the conservation division of an institution), and I am helping develop a method to label, identify and organize around 16.000 specimens of small beetles around the world. I got the other parts done, and now I need to address the "organize" part.

As shown in the picture, the beetles are glued to the card and arranged in order to display their appendages, and the card is pinned and stored in the collection.

I drew a die set in Solidworks and sent to a lot of machinist to see how much they will charge. Lets see if it is a reasonable way of doing this.

>>1466393

I don't want to spend a lot, but I honestly don't have a budget. If the only way to do is expensive, so be it, I really want this shit done. Also, fast is not necessary, I just want to be really accurate.


The pic is not mine, someone sent me, but it illustrates the idea. Also, I discovered my first species this month, and it also will be on the collection after I name and describe it.

>>1466720
So why glue the beetle to the card?
The most common way is straight pinning with smaller specimens glued to a point that is then pinned. How are you expected to look at the underside if it's glued down?

Carding is a way of securing the specimen, in a way that pointing exposes all the fragile parts. It is the most common way of preserving small coleoptera in Europe and Asia (and I think South America). It is only used in really small beetles, and the larger are pinned through their right elitra. The glue is extremely water soluble, so putting the card in water for 5 seconds free the specimen. Usualy this is not necessary, because most times, the specimen can be identified by dorsal characteristics or genitalia, that is usually dissecated and attached under the card, on the pin too.
Also, pinning sometimes can obscure certain identification marks, as in this Coccinellidae. A permanent glue on the right side of its body would (maybe?) hide one of the underside dots, and even if using a water soluble glue to release it for identification, the crooked position (in oposite to the total flat position of carding) could (and definitely would) damage at the very least an antenae.

To be honest, I think pointing is only used for coleoptera in the USA. I never heard anyone from other countries doing it.

Here is a "how to" video on carding coleoptera:

These are great, but I would prefer to have a way to make them myself whenever I wanted, and keep it padronized. Maybe in 5 years I will need more, and a supplier may not carry that shape anymore.

Pointing, not pinning. My bad.
