I am in the process of building another large table and I am using a huge walnut slab this time. The base for this table will be a steel base with large steel plates that will contact the floor. The overall weight of this table will be 400-500 lbs. I am looking for a product like the small felt pads you can buy to protect your hardwood floors from scratching but in a large size. I am looking for something in the neighborhood of 12"x24" or near that size. Any suggestions where this type of material can be acquired? I've seen the protectors in FELT and RUBBER and some other materials but never in the size I need. FELT is preferable because it will not stick to the hardwood floors. I did contact one company but they have a 5 yard minimum, a bit too much material.
