    We had a cove countertop using veined material the other day.  We decided to curve the seam to bypass the cove and sink.  Seam turned out great because the eye couldn't follow the straight line of a typical seam.

    This looks similar to the Sterling miter that Jon's cronies came up with.
    Was it difficult to hit the offset from the bit thickness, or is it too narrow to worry about that. I remember a good illustration that Travis, or Shane or someone posted awhile ago, showing how mirror cutting a radius seam had offset problems.

    Tom, that was actually Seth Emery that had the diagram of the offset.  Where the heck has he been lately anyway??

    Seth has been around.  He has uploaded many of the DXF files.

    Tom,

    I drew an arc and cut the counter apart.  I didn't actually cut through the top with a single cut.  Each piece was cut seperate.  Worked really well.  In this case I had to get around the sink and the cove splash.

    Great idea Andy. 

    I am too chicken to try a curved seam, but I have done a 30 degree angled cut to avoid coves, sinks, or to catch a filler strip at a corner.

    Is that Mystera?

    The Material is Corian Tumbleweed.

    The curved seam is really not that scary cause you can check it before you put the edge and all.  We just cut the pieces and pulled the seam before doing anything else.  It fit 99% good so we block sanded a bit and got it perfect.  Then we proceeded with the job.

    For this situation, I had no choice so I just went for it.

    Nice one Andy........ With all of these new patters coming out it looks like we will be doing some crooked repairs also.

    Andy,

    CNC, or just a router cut?  MIrror or one side at a time?

    We did use the CNC and single cut each side.  I talked with Kevin Andreas the other day and I think he may have something for this to cut by hand.

    I think if you make a gradual curve you can get a mirror cut to work pretty well.  Might be a little off but nothing a block sander can't fix.

    I would  imagine the tightness of the radius and the diameter of the bit are the major factors.

    I think Jon might have come up with the Sterling wave. Jon, you out there?

    What are the buckets for? I mean the color of that top is bad but not that bad. Nice job on the seam though.  Please Andy, tell me you  don't make you guys fabricate on benches lower than 36".  Man that just ain't right. My back starts hurting thinking about it.

    Wes,

    The buckets are for money.  Andy  runs out of  minivans to keep it in.

    Those are trash buckets.  We don't allow anything on the floor except dust.  Learned that from the aerospace industry.  Clean = effecient, Effecient = more money.

    Andy,

    I know this is not the point of this thread, but I have a couple of questions about your horses and the stretchers between them.

    1.  Do you have trouble with the stretchers falling over?  Are they screwed to the horses?

    2. Do you use this set up to pull seams also?

    Sorry about going off topic, but I am going to have to add some new fab space soon and can't decide what to build.

    The horses are cheap and easy.  The stretchers are not screwed down at all.  They have fallen off in the past, but it is not typical.  Reuben had a great idea about buying stretchers out of what I assume are floor joist for a house.  Maybe he will chime in or you can look for the other thread about it.

    Everything is designed to fit inbetween the edge and the sink and the best part is they are relatively inexpensive and very mobile.

    Yes we pull seams on them.  Be sure to make them perfectly flat and use glue.  Otherwise they will flex in the middle.

    Andy,

    Thanks for the info.  After posting I remembered the post by Reuben also and went back to take a look.

    Two more questions...... How much distance can you put between horses before you get flex/droop?   Do you use shims or something to compensate for non flat floors?

    We put the horses about 6' apart.  We do use shims to compensate for any unlevel areas, but only when we are pulling the seams together.

    UPDATE:

    I have been trying this crooked seam thing quite a bit on the patterned Corian material.  Check the pictures below.  Worked perfect and saved me buying a half sheet of material.

    The Paralign Clamps pulled it together real tight.  About 98% perfect.
