New Soliloquys with spikes and hardwood floors

To isolate there are pro-products for that or a DIY sandbox.

If you meant couple w/o damage to wood flooring...
coins dimple and that dimple tranfers a dent.So crazy glue a nickel with a penny on each side.

I've used fired pistol brass with Soliloquys tall long point.The head of pistol brass is thick and strong with a small center hole inside and nice bevel outside.
