I didn't do It all by my self, the turner helped me, giving me hints and tips ;-)

Re: Old lead
Sorry to reopen an old post, but this looks like the most relevant discussion. In hunting for suitable lead for a lead castle here in the US, my two most promising options right now are sheet lead (to roll concentrically), or lead shot. I am looking to use a standard US 1 gallon paint can (195mm h x 168mm d) as an outer shell. Lead shot is most commonly found alloyed with 5% antimony for hardness. Small lead shot (number 9, which is 0.08 inches / 2.032mm) would seem to be a good compromise between shielding and ease of assembly. I don't want be having to smelt my own lead, for many different reasons. However, would the antimony cause any issues either with reactivity or a marked lack of shielding?

Re: Old lead
Hi Steve, I don't think 5% antimony could be an issue for shielding, but in addition to that you should also consider the density of the lead shot, the "fill factor".
I think that a rolled sheet lead is a more compact solution, to have best shielding with the same space.
I would strongly discourage you to melt lead by your own, but if you find someone that could melt it for you in rings (in a professional way), I think it will be the best solution.

Re: Old lead
Antimony will add another fluorescence line around 26keV in the background spectra, adding copper liner you could attenuate much of this line at cost of slight increase in backscatter.
