How to clamp V-Grooved Solid Surface C-Tops10/8
We are looking for feedback on clamping the front edge of solid surface tops that are V-Grooved and then folded over. We use a profilematic V-grooving machine and have been having issues with how the seam looks after we apply glue, fold it over, then sand and polish. Most of the time we can see a seam line as well voids (sometimes large) within that seam where glue should be. Our clamping method is just to apply a thin bead of adhesive, fold the edge over, then just use tape to hold it in place.
This has been driving us nuts for a very long time now. We have tried changing the angle on our cutters, played with how much glue we put into the seam, used different tapes, etc...
Since we got machine i have felt that we got better results and seams that you can barely see by doing it the old fashion way which is the build up method. With the right color and pattern and if fabricated properly, it should be very difficult for someone to locate the seam. But with using this machine it is just so obvious that there is a seam and it drives me nuts.
So, is there anyone out there that also uses the V-groove method to fab solid surface tops and what method of clamping are you using to get successful results? Any feedback or recommendations would be great.
Also, we typically fabricate tops that are 25" wide with a 1 1/2" fron edge.
Are you running a full strip of tape centered on the seam as a hinge before folding?
Im sorry,yes we are.
hot glue a beveled strip of wood on each length and use spring clamps. You are not getting the pressure you need by folding the edge over and you will see the seam. make the strip triangluar so that when you glue the strip the pressure from the clamp is perpendicular to the joint.
Dave, thanks you for the tip! I will try this the next time we run solid surface throught the shop, which will be soon. The only problem with that method is how much labor is added when your doing 20 tops...
Matt, Thank you for your response. I WILL look into this. I just looked at that part and it does seem to have some damage to it already. And it makes sense that if it's off, so will the depth of your cut.. Great response..
David, Glad to help.
Regarding your original question on how to clamp the miter-folded edge; please see the attached sketch. I have a couple benches configured this way. Fast, easy and perfect edges every time. 1-5/8" tall curb w/ 1/4" foam. A 4-5/8" curb is used for folded back splash.
Good luck to you.

Matt, do you clamp the top in place?
So, you just fold the edge over and then push it up against the curb?
Large (i.e. heavy) tops just push in place. Sometimes a small one needs a clamp.
