Not X carve related, but woodworking in general.
I came across this guys channel not too long ago. He has some great woodworking tutorials.
He is doing a giveaway for the parts to build his table saw sled design. Thought this could help someone here who might be interested.
Was just thinking about pricing out the parts for this sled, then figuring out a similar design using the aluminum extrusions from inventables or open builds.
Another great channel I started following is Jay Bates
