After getting replacement windows for my house i saved the old windows thinking if several projects for them. The major problem is several of the sashes are painted with lead paint. No Martha Stewart you cant just paint over the wood. At least not in Massachusetts. So always take safety first. Do this on a drop cloth like an old shower curtain. Ware a dust mask. Wash your clothes separately not with the kids. Keep all kids away until after the clean up. Also we will be using razor blades and have the potential for sharp glass.
Sorry about the pictures there is no flash on my phone and the glass was transparent.
Your going to need
a razor both the double pointed (like in a box or dry wall cutter) and the straight edge both with holders
flat head screw drivers
soap & water
small pliers (needle nose work goodgreen scrubby
