Special Bolts for Cast Iron bath feet
Having started to clean the outside of my CI bath for repainting, the
amount of muck around the feet and the fact they were slack lead me into trying take them off. The first bolt came off OK but the other three are rusted such that the heads are turning and they will require to be cut off. The one that did come off shows the bolt to have a special shape - anyone know anything about the history of these, if they are standard and if these are available anywhere? Rob |

Neither heat nor mechanical hammering is sensible considering this is CI and is enamelled. There are thread type nut splitters on the market which I could use but the bolt heads have rusted such that they are turning so need replacing anyway. If the worst comes to the worst I'll have to make them from scratch but they're still making CI baths so the bolts may well still be available in some shape or other.

The first bolt came off OK but the other three are rusted such that the heads are turning and they will require to be cut off. Try not to cut them - first of all try heating in a gas flame, cooling, repeat, attempt to undo - if this does not work, split the nut. To do this, hold a block of metal such as a club hammer against one flat of the nut - at the other side position a aharp cold chisel and knock it into the metal of the nut with another hammer. It micht help to have an accomplice to hold the club hammer in place! /Cold chisel __ / /\ / \/ \ / \ metal \\ / block \\__/ Nut \ / Hard to draw, but hope it makes sense. You probably won't need to cut the nut off, as the "hole" in the nut expands as you apply the chisel it will most likely turn easily before you cut it. The one that did come off shows the bolt to have a special shape - anyone know anything about the history of these, if they are standard and if these are available anywhere? If you remove the nuts, even as above, the thread should be OK, so you will just need new nust (an "old fashioned" ironmonger will probably have these or know where you can get them). __________________________________________________ ______________ Sent via the PAXemail system at paxemail.com |

Yes, you said that in your original psot. It can be done, it just depends on whether you are ham-fisted or not. Use a small hot flame (like from my Turbo propane torch) - shield the bath shell. Use a club hammer as support as in my post. It's OK. There are thread type nut splitters on the market which I could use but the bolt heads have rusted such that they are turning so need replacing anyway. Ah. Your OP led me to believe that you were trying to preserve the bolts - so just cut them off & ask a simpler question such as "Where can I get this sort of bolt?"! What sort of special shape are they, anyway? __________________________________________________ ______________ Sent via the PAXemail system at paxemail.com |
