Expanding Aluminium Honeycomb core

Hi,

We ordered 6 pieces honeycomb core to use as beds in our lasercutter. It's really cool stuff but we aren't able to easily or nicely expand the honeycomb core. We have tried the suggestion of using a number of nails spaced at the cellsize apart, but that didn't work out since we needed to pull so hard we pulled the nails through the core. We tried using rope through the holes and a wooden stick to expand it, didn't work.

Finally we found placing 2 hands on top and below with two persons we were able to each pull on a side and that worked but didn't expand it evenly so you get like a weavelike pattern throughout the honeycomb.

Then we tried lasercutting different size "combs" of wood and place these in the honeycomb material this seemed to work sort of.
Attached are our pictures, we want to extract it to a nice square size.

Does anyone have a video online how to do this or some better tips than to use nails in a piece of wood ?

Material is of very nice quality so thanks Easycomposites for the cool stuff and ultra fast shipping !

Kind regards,
Hobbybob aka Dimitri

That's why I'd rather pay the extra £15 and get them pre pulled to save he hassle. 

My last company thought they would try and save money by having us pull out each sheet 4 men grabbing a corner each and it looking like a banana is not ideal.
