Another train related use for an otherwise unrelated item, the Zip Tie. I picked a zip tie lying in the alley behind the house this morning while walking the dog. I'have used these things at work, our church bazaar, and at home, and today it hit me, ramps! The tie in the photo would be more suited to HO or S, as it is 3/16" wide. In O, it would only be about nine inches wide. The larger wider ties would be good for O gauge though. I sprayed it silver first, then misted a coat of gray primer to dull it a bit. I cut these at an inch and a half just for a better photo. Half that length would be more appropriate.
