This device is twice lighter then our press for boards)) But yes, it is still looks heavy) Since we need to sublimate our bases we need big pressure, that is the reason why the frame is big. You are almost right. It is sandwich of nichrome in the mica covered with two stainless steel plates. Energy ...

Here is ours sublimation press. Easy and fast to work. Not that I planned to make, but still works good. Nice uniform pressure. Instead of foam we use plywood. Works great. Instead of heat blanket we use hot plate made of nichrome wire. https://s18.postimg.org/78mngnylh/WP_20161015_11_48_09_Pro_1.jpg

The result is not so impressive, but still good) Now we are waiting for mature trees) We were told that in 5 years there will be able to cut them ...

Even 10 mm tool is hard to work with for our spindle, since the noise during cutting is not normal. I tried to cut 2 mm depth at speed 1000 mm/min and a few times spindle stuck in the place.

I did an experiment and got good result but time of work a bit long. Even sidewalls remained in place)) Right now I use 6 mm 1 flow bit for wood at the speed of spindle 18000 rpm and spindle feed 4000 mm/min. It takes aprox 1 hour to work 10 mm core. We will buy better spindle with water cooling sys...

Thank you Gilo for a great advice. a few weeks ago did an experiment following this method. The result is fantastic. Looks expansive. Yes, there are some textures from peel ply but still it looks good. Here is the pic. https://s9.postimg.org/621sddfpn/WP_20160808_16_02_22_Pro_1.jpg https://s9.postim...

Dear Gilo, I have never used peel ply. As far as I know it suits good to be easy unsticked after cure. I will do some experiments today with epoxy. I will make long and thin samples in order to check flexibility of the epoxy. Now it is main question for me)) Is it strong enough not to crack? I don't...
