I'm a little bit surprised by the weight. Not so long ago I designed a press like that but I came up to something like 6-700 kg without mold and so on. Would it be possible to make some little drawings from the press because I don't completely understand the way you've built the vertical parts. Geoff

That's another way ;-)

Is it a nice cut in that case or do you have some warping?

The VDS rubber foil which is sold by SBM is non perforated 1" rubber foil. The minimum width for perforated is 55mm One of their suppliers is Haberkorn which is shipping only in bigger quantities and can cut the larger rolls of non perforated foil to 6mm width. Cutting such rolls from for examp...

Hi,

I still have a couple of rolls I ordered a couple of weeks ago
25mm wide 0.2mm thick and 70m long.

Have a look at the sales forum.

Hi there,

I just got the VDS rubber and it will be 27 Euro plus transportation which can be cheaper than SBM even for US-citizens.

Best regards,

Geoff

I ordered already a couple of rolls of VDS rubber and will probably have some to provide to others. Look at the sales forum for further information.

Best regards,

Geoff

I ordered some 1"/25mm VDS rubber rolls. I will get them by the end of January. I will get more details about the price but I expect them to be 25 to 30 Euro per roll of 70 meters. Shipping charges are from Belgium, Netherlands, Germany or Switzerland as I'm travelling a lot. PM me if you want ...

Hi,

I contacted Haberkorn and they told me the smallest width of perforated rubber foil is 55mm, not perforated rubber foil has a minimum width of 6mm.

Where does SBM get their foil if they sell 1 inch/25mm foil?

Geoff

What is the best way to bond steel edges on base and fiber? Do you have to threat them to get better bonding?

For a possible solution have a look at

Great video

Mainly their use of materials is interesting

I know about that topic but it doesn't explain about the type of foam and what type of strips are used.

On the goode website you can road those strips are dampening vibrations.

Geoff

If you have a look at their website you will be able to read they are using 2 biaxial and 2 UD layers of carbon at both bottom and top.

It doesn't surprise me they are so stiff.

I'm wondering however how they build up their cores.

Geoff

I think you gave us a bad link because I only see two pictures with a guy on them. I also can't see a scratch on their face ;-)

It is very interesting to read this.

Would the top layer have ripped of, if the binding hadn't come off?
I was thinking about adding a wooden 3mm plate to the core at the binding part.

Maybe there is also a better epoxy or adhesion to be used with pvc foam.
