Is anyone using the Barb Dado joint in production yet? How is it working?

I am going to wait for one more update to switch over to it. I already found problems with CN 5.59. I think that takes care of my duty. I still have to find out the tools that it requires.

Georgi,

Thermwood,

How did the Barb Dado perform at the IWF on the Habitat for Humanity cabinets?

Hi Guys,

There is only 1 tool that takes to create the barb dado. We currently have a .25" dia. tool available and working on a .3125" dia. tool.

The Barb Dado worked very well at the IWF show. We cut at least 2 units (1 unit is 45 sheets) of plywood from Columbia Forest and had cabinets stacked everywhere. We would apply some glue, assemble the cabinets and set them off to the side with no clamps. I would also like to hear from others that are using the Barb Dado to get their opinions on how it is working for them.

Jason, what fit clearance did you use? 0.030"?

Hi Rob,

We normally use .015" - .02" as the fit clearance. I don't know if I would go any smaller than that. It really is going to depend on what works for you.

Hi Jason,
Its interesting that Kerry is asking about this Barb Dado. One he hasn't a Thermwood and two he is hanging around in the 3 axis forum. Kerry may have has been squirreling his money away. :D
Maybe Thermwood has a spare one they can cut a special deal for him?

Getting serious now. The talk is on plywood application. How did the particleboard and MDF perform in your tests as that is our main construction material in Australia. No ply is used in Kitchen manufacture.
If it doesn't work on that particleboard material maybe Ken could think of a way to achieve that as it would be a big hit.

Regards

Neville,

Just looking into outsourcing boxes again.

I think the problem with particle board is the fact that the barb tool cuts can loosen particles that would dislodge during assembly and fall into the groove beneath the tenon which would be a problem. I think you would just have to try it with your particular brand of particle board and see what the results are.

Hi Kerry,
Yes the particle board density does vary from Manufacturer to manufacturer. I was hoping it would stay stable enough to allow the glue to take over and set rather rely on the barb joint to hold it together.
This is one big advantage of Thermwood over the other machinery suppliers. They look at finding ways to make construction faster and easier without sacrificing quality for the users of their products.
Glad you didn't take offence at my jibe. Its good to see your comments.

Regards

Hi Neville,

Kerry is right. We tried the barb dado construction on plywood, MDF, and PB. Plywood and MDF worked but PB didn't work as the barbs would flake off due to the density.

Thanks Jason for the reply. Mdf is workable but Particleboard is a lost cause.
