We actually try to sub out all the countertops to a solid surface shop.
The current job we're doing uses about 60 sheets for base, wall panel trim, cabinet trim, and window sills.

Gerry; While it is generally thought that Arizona is mostly dry, our humidity does vary greatly throughout the year. We're just on the other side of the scale our RH varys 5%-45%, most others are 30%-70%. Most people forget that a hot airmass can contain way more moisture then a cold one. With the $hit MDF available here I still have problems. BTW last summer box jointing about 600 parts, I thought I was having moisture/wood movement problems and programmed a huge 0.012 clearance in the joints. I download your latest version and reran one with 0.004 clearance and now

Default Removing corian countertop edge lip

I found the easiest way to remove the drip edge is to hit the edge of the lip with a hammer, it generally separates near or at the glue seam. I spent time cutting one last month and then found the hammer method to work way better.

Xray, congrads on corian motherload. I come across those occasionally. I still make a lot of cutting boards with it but customer brings me material and I cut it. I started making spoon rests from pieces that were 4x8" which is basically scrap. I use vacuum systems for holddown since I do so many now.

Corian is somewhat brittle. I've broken off sharp corners dropping it on the concrete. Curved edges don't break so easy.

Nice work Rich, corian is a very versatile material that holds detail better than just about anything I have ever seen. Easy to machine, attractive and takes paint well if necessary, downside is cost, which is negated when a scrap hoard like this is found. The guy was asking $50 for all of this and I gave him $70. I have already made a profit from just a 8x12" project I made which I sold for $90.

It can and will break if abused for sure, I just don't agree with the dictionary definition of brittle which is "hard but liable to break or shatter easily." That to me would be something more like plaster or glass. It is not fragile, the only care you really need to take is don't drop it on concrete - And even then it will just bounce more often than not. Guys that work with sheets, sure proper care is in order when handling it, I imagine they would fracture much easier than a 10x10" square.

Can you describe your hammer separation method a bit more, do you put it on a wood block or what ?

I don't get too many actual counter tops but the last one I did, I just had it laid on the grass and start whacking it along a 1 foot area. I had been sawzawing it but that was pretty slow. Just try a small section. No guarantee, it could be that the adhesive mixture could be different. It won't necessarily break exactly but the small offsets made the labor efficiency well worth it. You can just hold it down with your foot or just let its own inertia hold it back and let it move some. Just give it a good whack.

If this is counter top laying upside down:

Hit here->] <- drip edge
-------------
___^ top ^should separate here.


Corian is the best to cut, doesn't splinter or leave ragged edges. I normally use a 1/4" upcut to a depth of .2" at a speed of 100-140 ipm at rpm of 12000 rpm. Key is to keep the bit cool. I used to go to slow and it was worse for the bit.

I have found that the X3 is one of the best machines for cutting boards. I generally use 2-3 bits but only set up one board at a time since I use remnants. One of my customers has thousands of pieces of corian but I only cut 50 - 75 at a time as he needs them for shows.

Cutting is no prob, even my 18v trim saw has no problem with it. I clamp on a straight edge and it cuts like butter.
Downsides are the wastage and terrible mess.
