That's the sander they used on my slabs. Then finished up on the other one.Price-wise i would definitely try the Hardwood Store first. Raleigh Reclaimed is more expensive but if they are the only option for something that big, then you pay what you need to pay. Attached is a picture of my 44"x108"slab coming out of the large belt sander at RR.
Gibsonville is 1-1/2 hours each way for me. I did find another place in Raleigh that could have done the job @ $50/hour. I would have had to drop off and pick up in a week. We are already behind schedule on this job, so that wasn't going to work.
Also, Daniel (tri4sale) can get them done on his cnc router.
