Thread: casting furniture joints

Casting resin is not flexible, it is very brittle.

I'm a bit confused on the joint you are talking about. Is it a joint between sheets along the edge, or a joint only in the corner? If along an edge, I guess it would be a rod with a slot. If in the corner only, I guess what you are after is a block with slots in it. I then would not cast around the pieces, but cast a block/rod, then cut slots as required. Casting around them would not be easy.

Hope this helps

My first question is.. why cast resin corners?.....I have done much work in resin and for all the reasons you bought up is why I ask the first question...
If you want black corners paint them you can cnc them out of wood or PVC to mount you bamboo in and glue it all together this is very strong construction and will be quicker then casting resin by any method
That's my $0.02

Thanks for your replies. The reason I was considering casting the joints was because I want the corners curved (radius of, say, 30-50mm) and I like the contrast between black resin/plastic and bamboo, or woodgrain for that matter.
If resin is too brittle, then I guess it can't or shouldn't be attempted.
As alternatives I am considering CNC routing of quarter of a black plastic pipe, or formed ply, but these methods have their own issues

Hi Andrew,
if you contact Nuplex Composites they do have a flexible resin and you can alter the flexibility by adding some standard casting resin to it . It is generally used for casting architraves and cornices.

Hi Andrew,
Do you have any photos or drawing of what you want would help a lot here

Seriouly chum, if you have access to CNC machinery there are some far better ways of doing this.

And start thinking all wood (consider Bamboo a wood) and epoxy.

If you can lay your hand on a coppy of "The Gudgeon Brothers on Boat Building"..a read of that will tell you why I say what I do.

well made joints of timber to timber with epoxy will be stronger than almost anything else you can make and you could achive a smooth flush rounded finish.

Back before "Rocker" set sail for the mother country, some of us where involved in testing some of Rocker's epoxy joints to distruction.....there are many witnesses here that can testify how strong an epoxy joint can be.


All you have to do is lay your hands on some dark timber or blacken some timber....and maybe black black nyow not be the best.
A dark brown almost black would look more natural with bamboo.....some queen ann ebony for instance.

cheers
