I am a renter,not a home owner. My landlord is elderly and when something needs to be repaired he usually hires a particular "handyman" who usually ends up making matters worse and very expensive so I usually try and fix things myself. The house is probably close to 100 yrs old and I can't say whether the windows are the originals or not but they are old.They are segmented into 6 sections on the top and six on the bottom. Anyway getting to the problem I have, the other day I accidentally broke the top corner pane in one of the windows. I took all the glass out and cleaned out the old putty. I have all the supplies I need and I am pretty confident that it won't be a problem,except for one snag. When it broke the piece of frame that segmented the broken section from the one below it also broke. It broke in 3 pieces and they are not in any condition to go back up, the piece needs to be replaced. The question I have is can I buy this piece ready made or do I have to make it myself,cutting the grooves in it for the glass to fit into and cutting the pegs on the end that go into the frame? I have very limited tools. Basically I have screwdrivers, a drill, a hacksaw,pliers/wrenches and a hammer. Thats it, so if I have to make the piece from scratch I don't know if I will be able to without going out and buying tools. Does that specific piece of the frame have a specific name? Anyway thats my problem/question,thanks for the help.
