Melissa,
A thought on strengthening the ends of your mdf clamps. The guys who build the mdf routers have used thin cyano adhesive to give additional strength to mdf , maybe this would work for your clamps as well?

Yes Steve, the machine should, and can, remove the tabs. A bit of smart programming is needed, but this is worthwhile for repeat jobs.

For reference here is how the tabs are removed with a trimmer.

Watch the video to the end and you will see how quickly it can be done as they unstack the cut sheets.

You have the machine to make boxes that don`t need glue or screws to assemble

Camille,
I grew up just outside Cleveland (Akron really) I and have had my long winters of wet and really cold snow from Lake Erie. That's why I moved to Florida! :)

Sean,
Come to Canada, we will show you a real winter. :)

Oh, were not going start the "well, it's really cold up here!". I spent enough time in NewBrunswick, Calagary, Thunder Bay and Toronto to know real cold! Again, That's why I don't even own a winter coat anymore! :)

Hi Ross,

I cant figure it out unless it's a short bit with bearing on top. And it rides the edges while tip is cutting tabs?
Some very short bit like this one?

If there is a bearing, it is typically at the bottom (else it can gouge), but sometimes it is just solid carbide with a blunt bottom. see: http://www.google.co.za/search?um=1&...1500l2-3.2l5l0

If you are going to do a lot of trimming invest in a Festool edge trimmer or a Lamello edge trimmer.You can do really fine adjustments on them.

Hi All

Yes the bearing is at the bottom of the straight cutter as Gerald has indicated.
The bearing follows the machine cut part of the profile and trims the tabs off.
Even once the part has been cut free any roughness can be further trimmed freehand.

In general though, the machine itself should do as much of the work as possible.
If the table is set up well trimming of very thin tabs can be cut with a "Stanley" knife (a very sharp cutting blade).

If the job is small enough to manipulate hand; I prefer to place a piece of sand paper on a flat surface & bring the job to the sand paper, all it need is a single rub at the right direction on the edge.

Silly me ! the board is turned over and then trimmed, then its easy to figure out why use bottom bearing :)

HI Melissa,

Looking at post 309 the V-roller appears to be pitted. Maybe just pitch form the wood or is there some grounding issues. I noticed you have ground wires.

Boxes look great. On the inside corners of the tabs did you go back and trim them square to get your fit where the matting side comes together?

Gary, as I recall, the black on the V-rollers was just crud building up, not electrical arcing.
Also, yes, we trimmed the tabs to get the pseudo-dovetail to seat fully.
