While my wife was away for the weekend, the boys (3 year old twins) decided to surprise her with a new coffee table! We had to get rid of the old IKEA one due to its sharp edges... we've already had one ER visit and nine stitches!
A few notes/things I learned:
* Pay attention to which side of the wood you leave facing out. A lot of my boards had one smoother side and I accidentally put those face-down. Meant a lot more sanding.
* A belt sander would have made this a lot easier.
* I took care to round all the exposed outer edges with the sander. A router would have been better for this, as it took a lot of care to make sure they were even.
* It's going to get about three coats of polyurethane now, but I still would recommend coasters.
This thing is HEAVY. It will probably outlast me. :)
