Edge Banding on End Panels

Joe Elbert · Post by **Joe Elbert** » Thu, Jun 14 2007, 12:26PM

My question relates to the left or right end panel on a frame less upper cabinet. We use a veneered deck panel and require edge banding on the bottom edge of the left & right end panels. When adding the edge banding, the end panel is adjusted for size to allow for edge banding. But the joint (blind dado) for the deck is referenced from the cut edge of the end panel, which allows the end panel to extend past the face of the deck panel, by the thickness of the edge banding. Are there any work arounds that will adjust the joint so the edge banded end panel and the exposed face of the deck are flush.

Thanks for your help
Joe

Joe,
You can inset the front of the end panels to allow for the edgebanding.
I only inset the bottom of the end panels for edgebanding. I use +.028 bottom inset, you can do this for the front edge also.

I wonder if this is correct? I inset the bottoms of the end panels and the bottom as well by 0.125\".

Joe,

The edgebanding is accounted for in reference to the bottom of the deck. If you are having problems you may want to check your material thickness. If the material is thinner than ecabinets thinks it is the sides will hang lower.

If you use a negative inset the side will be longer not shorter.
You want a positive inset on the bottom of the sides only.
Leave the deck where it is. This will change the size of the cabinet.
This way the cabinet is flat on the bottom and the edgebanding is not sticking below the deck.

But as was mentioned, if you go into edgebanding editor and add edgebanding to the bottom of the sides and your edgebanding is set to the right thickness (with the glue) all this will be taken care of in the software.
I don't have a very fast computer so I don't add edgebanding to anything. It just adds more overhead to a slow computer anyway.

Thanks for setting me straight, Roger.

I was puzzled at first, because it was not working properly on the example I posted. NOW, without ANY insets, the sides stay at the desired length, and the edge banding is flush with the bottom of the deck. I must have had an inset, somewhere. Just cannot for the life of me figure out where

, and cannot reproduce what I did earlier.

Forrest is correct. Also check your edgeband thickness you set up in the program to make sure that jives with what you are actually using and make sure you set the material thickness for your veneered panel a few thou less than actual and that should flush everything up. You might have to tweak your material thickness till you get it right as the thickness varies throughout the sheet.

Thanks for all the advice and help. I now can get the end panel with edge banding to graphically appear correct, but when I try to cut the cabinet on the cnc the end panel is flush with the deck, so when adding the banding the side extends past the deck by the thickness of the edge banding. I have used a bottom inset on the end panels and that seams to work for the machining. Has any one found that using a inset the thickness of the edge banding to be a problem?

Thanks
Joe

Hi Joe,
Are you changing material thickness when writing your twd file?

Mike
I am using the material thickness that is entered in the library. It appears that the dado is referenced from the cut edge of the panel not the face of edge banding.

Hi Joe,
If you are not changing material thickness at twd, maybe your discrepency is actual material thickness vs. what you have entered it as in you material library. Say you have 3/4 vcp material entered as .750 when it is actually probably .725 to .730. This will possibly cause your problem. Changing thickness at twd will also do the same thing. I have experienced both. If either of these could be your problem, you might set up a material to exact thickness you have, do a material change on a test cabinet, apply your edgebanding in the software, and then do a test cut for just a side and deck.This should be enogh to tell you what is going on.
