Question:

What kind of pipe is this exactly?

Cast iron or galvanized? Should I be concerned about any type of lead? It is a drain pipe that has either come loose somewhere and is leaking water onto the crawlspace floor or has a little hole in it somewhere. Pretty big pipe for just a sink drain that is about 1 1/4. The drain pipe is quite bit If it is a little hole, do they make anything that will wrap around it and seal leaks for years without having to actually change the pipe itself? I thought I remembered seeing such a product a long time ago, but I can't remember the name. If it has come loose, I'll obviously have no choice but to cut a section out and replace it.

Answer:

Use a 15 ft see-saw. Put the fulcrum at the circumterence of the 15 ft circle and attach a 50 lb weight securely on the far end over the can. Then use your weight on the opposite side of the see-saw to raise the 50 lb weight over the can.Then remove yourself from the see saw and the 50 lb end of the see saw will drop onto the can. Voila. 7.5 feet times 50 lbs will give you 375 ft-lbs plus gravity force to crush the can. When the can is crushed, get back on the see saw and raise the weight.
cos people of those times had slaves
Well, it looks like you asked the question 19 hours ago. That means that by now your resin is dry enough to sand. I hope you didn't use a hair dryer, resin hardens in an exothermic reaction (it actually produces heat). That's where the term hot coat comes from. The best way to time your resin is to mix resin and hardener in a cup, time how long it is until the resin gels, and then time how long until it hardens. If you mix it again at the same exact proportions in the same room temperature, it will harden in the exact ame time. Polyester resin mixes with hardener at a 30 to 1 ratio. You really should measure what you are using.
