They do look the same. Yours was cut with a laser and mine with a scalpel. That would have been faster. I'd have tried to cut it on our abrasive waterjet but as you know I only have the prints. Did you get that from Shock? Did you widen the tunnel on yours? I bought some additional supplies this weekend, but no progress as of yet. I'd say I think about it for at least 1/2 hr a day but no action right now.
