I forget the tool he had to buy but it is to cut through cast iron. The only way to remove that big metal back with the strings is in pieces.
I told you about the beat up old coffee table he got for $7 at the op-shop. I asked if I could play with it (since he had no clue why he brought it home LOL) I had some shabby chic in mind. So I cleaned the entire table with something called sugar soap...works well at taking old wax and grime off. I had to find their version of Old English. One thing the company that Rainer works for does, is make store displays and they use crackle finish. So he just happened to have the best damn crackle stuff I ever worked with. They should bottle this stuff.
