David,
What bit were you using to get such nice cuts in the BB plywood?

Hi Jay,

For this job we used a 1/8 single flute down spiral from Carbi-Tool a TSPL04S. It is supposedly designed for plastics but we use that series for all ply and MDF. There is little or no sanding required.

The other important factor is your hold down. On this job we use a combination of vacuum (a 15hp side Channel blower) and screws. This reduces the vibration of the workpiece and results in better cut quality. Also care with your toolpath strategy and not using our dust collector during the cutting process also helps. ( a bit messy)

There is a photo of this job being cut on our web site.

I have previously posted about the differences in cut quality using different bits from different makers. I find that there is a surprising amount of difference in cut quality in nominally similar bits from different manufacturers. Lots of experience and experimentation helps

David,

Thanks for the bit info. I looked back at your previous posts and I looked at their website. I will have to see what the shipping is like to the US. I have been having pretty good luck with Onsrud 57-040 bits.

Wow! He's taken it to another level. I wonder how comfortable those chairs are. They look like they would have lots of spring to them.
