Prokopto Posted June 30, 2011 Posted June 30, 2011 I found a few pieces like these in a river 40 feet beneath a railroad bridge. Does anyone know what they are? Quote
jimmy seale Posted June 30, 2011 Posted June 30, 2011 i have seen the "spiral" spike to tie down plates at rr crossings, the "L" is one they set and cast in concrete foundations to anchor things such as walls,rails,etc. Quote
pkrankow Posted June 30, 2011 Posted June 30, 2011 You can test them to see if they are wrought iron. The top one looks like it could be a hand made twisted lag bolt. To test you cut them half way through then bend them over cold. If they tear and look like wood inside then they are very likely wrought. Phil Quote
Francis Trez Cole Posted June 30, 2011 Posted June 30, 2011 the twisted bolts I have seen the and they are galvanized. So be careful Quote
Prokopto Posted June 30, 2011 Author Posted June 30, 2011 Thanks folks. I'll test them shortly. I made a pair of tongs out of the bent ones. It was darn hard to draw down at even a yellow heat. Quote
pkrankow Posted June 30, 2011 Posted June 30, 2011 the twisted bolts I have seen the and they are galvanized. So be careful I see what you are talking about with the coating. There is also some flash under the head, so it may be of modern origin. If it is coated then yes, be careful about fumes. Stripping with vinegar (overnight) or muriatic acid (a few minutes) is a good idea for galvanized. Wrought is supposed to move easily under the hammer. I suspect you have something else then.
