Corian Worktops

Jmb have a look at this YouTube video Ya man attaches a stainless sink to the underside with some sort of clips. Also he demos corian worktop techniques really well.
 
I am a certified fabricator here in the states.  First off, we attach the mdf strips to the Bolton of our piece with silicon.  The same goes for the stainless sink.  They make clips for the sink as well that aid in securing the sink mostly until the silicone cures and add a little confidence. 

There is a way to fab the backsplash without the cove rig.  I learned about it at the Festool End Users Class on Solid Surface in Vegas. 

Cut a 7/8" channel 1/8" deep on the back of the piece.  Take the 3/8" cove bit and cut a cove on a 7/8" strip leaving 1/8" on the bottom to stack on the back in the channel.  This gets you the vertical transition and leaves 1/2" from the cove to back of the strip.  Add the vertical portion of the backsplash and get ready to sand in.  I have only done this process once mostly because I usually do tile and glass backsplash. 
 
Seen too many sinks drop out to rely on silicone alone, frame to of unit to support the sink.
 
Any inset sinks I do I always cut some 18mm ply into the top of the sink carcass then cut and rout the sink in flush. That way the plumber can fit the sink ready for templating and can even fit the tap temporarily so the customer can use the sink while they wait for the surface to be templated & fitted. Also its a better job it has full support all the way round.

I used to fabricate Corian a while back.  We used to "double" up the sink cutout with scraps so you would have a 1" thick interior area around the under mount sink.  We would the  predrill holes around the sink, then secure the sink to the Corian using silicone and screws with washers so that the washers would act as a clip.  Make sense?

Also, if I were you I would sub out this job.  Sounds like you might get in over your head on a job such as this.  In the meantime, if you are really interested in getting into Corian fits, take the class.  Then start doing Corian jobs.

Ya I came across that earlier on alright. You guys are right I will sub out the worktops. If I had some corian to practice with I would be able to try out the technique but alas I don't
 
top form in gort will sell you some corian(i think its corian brand). i wouldnt bother with  trying to do it myself. i would rather get a few bob comision rather than having to by all those tools and coarses. and it will be someone elses head on the line  if it doesnt work out.
wait for a small job that you can easily do instead of a fancy complicated one.
 
Alan I never knew they did solid surface worktops. They are constantly ringing me every few weeks to ask me if I need any post form worktops. There's also a lad out in Tuam that does corian for a living.he can thermoform it and all.
 
I took a 2-day course at the Festool Training Facility in Henderson NV with trainer Steve Bace who is very highly skilled at working Solid Surface --- What did I learn:  (1)  I DO NOT want to do this for something as complex as a kitchen for a customer or friend.  I might do it for myself.  There is a tremendous amount of hard work and lots of things to go wrong if done incorrectly.  Some of these problems will not show up immediately, but will over time.  (2)  I learned I will do this for smaller furniture items, libraries, bathrooms, etc.  They are not nearly as complex.
3.  Festool tooling  --- saws, guides, routers and sanders are extremely useful for doing this work.  4.  I respect those who can do complex kitchens correctly.  5.  If you are going to do this, get certified
