I'm in the process of making a Celtic Love Spoon similar to the ones posted in another thread. It's a 2-sided carve. On the first attempt I used the new dust collection adapter by Carvewright on a Cherry board. What a mess! There was sawdust all over everything and I had to use air pressure to clean out the machine when the piece was flipped over to the front side. The same thing happened on the front carve.
Since I didn't get the depths set correctly and it carved completely through on the spoon end it had to be re-carved. I thought this would be a good opportunity to evaluate the differences between the RNB and the new CW DC so I re-mounted Floyd's RNB for the second attempt. What a difference! There was hardly any sawdust left in the machine or on the board on both sides of the carve.
Now, I did use Walnut on the second attempt so not all factors were exactly the same. Still, it should be close enough for a pretty good evaluation. Floyd's RNB out performed the CW adapter hands down. At least this time.
