Cast iron Sash window weights
« on: February 09, 2019, 04:26:42 PM »
Has anybody found sash window weight a useful source of  Cast Iron? Or are they too varied with hard spots to be usable?

I have just been given a dozen

They make great weights for bottom fishing off shore, Seriously, they seem to drop to the bottom faster and I would be reeling up fish while others on the boat were still peeling out line, less tangles for me as well.

I brought four home from work, two smaller and two larger. There wan't a whole lot of difference between the sizes I think the larger ones were maybe 30% bigger but the two small ones were unmachinable and the two larger machined quite nicely. I've made quite a few bits and bobs from them.

Bottom line - it's a lottery. Depends on how quickly they were chilled I guess.

I do not have a lot of experience in these things, but i do have some that came from a Very old house. One or two that are 4 feet long most round but again three or four that are square. All machine very well and not come across any hard spots ...YET!

You can always soften them again, heat to white hot and cool slowly.

Here's a large square one glowing nicely in my 100 kw induction furnace when I had it set up back in  2007

(just had to manually ramp down the power setting so it cooled slowly rather like you would with a pottery kiln to avoid cracking, which was easy as it's a  big knob on the control panel!)

Thanks for the replies, looks like they are worth having, I guess pre cut lengths could be put on the coal fire in the lounge to soften. Donít know what it is love must have come in with the coal.
Donít know what might happen to the carbon content?

I have three about 18 inches long that I turned round.  Two looked good.  The other one has some holes and pits.  I have made model piston rings from one of the good ones and they worked well.  Some will be good and some will be bad.
