segmenting acrylic

[Bigblackdog]

If I make a segmented acrylic blank, how smooth/flat to the pieces need to be- presumably more than bandsaw flat, but do they needed to be sanded to 320g or more?

what glue can I use that will be completely colourless and invisible?

I have sanded to 240 and also used a stanley knife to put a few keying lines on and used thin Ca medium and thick, but the thin set to quickly so I now use medium or thick it gives more time to get into the right position, I have also used epoxy, but I find that too messy so I prefer CA.

Like Peter I use medium ca & it works fine. I sand the surfaces with 240 grit.

Would the special glue used for Corian be the best it sticks like Tar to na Tomcat and is invisible.

Why not band saw smooth?

When I do knots in acrylic I don't sand down I just cut through the blank part way and glue up.

Never sanded foe segmenting.

Always use ca.. But epoxy when I run out.

Try to get a good flat finish to the joints Mark, or the glue joint is very much evident .. Thin CA goes off very quick and if you lose the joint you don't have time to pull it apart .. As above, Medium is the best, and holds well ..

because rightly or wrongly, I had assumed that it would be difficult to get a perfectly flat face for an invisible glue line. I want to split a blank lengthwise, so if the cut is not perfect, I think that it will be obvious, but could be corrected with sandpaper on a flat surface.

point taken though- your results show that your methods work!

But I may look at sanding tho, see what the benifits are!

Always willing to try something else, might be where I am going wrong.

Hi Peter

Glue sold specifically for Corian isn't clear usually it's especially colour matched to the Corian sheet so you can make invisible joints. (An epoxy acrylic/stone mix and bloody expensive).
I know this as for my business, I have bought it a number of times for kitchen worktops as well as other brands.

I still have some of the leftover colours with the thought I might mix them and cast something. One of those " if I ever get around to it things "

Thanks Bob those joints in Corian are excellent thanks for confirming the benefits the colours I never heard of before.

I sand mine on the disk sander that way I get a perfect flat surface and a ket for gluing

Corian is really hard to get here,
