Cast iron ''SPRUES'' can they be of use to the model machinist?

kellswaterri:

Hi all,
visited our local Railway Museum Engineering workshops today...after a wander around and a bit of a chat I left with a fairly large and heavy bag of bits of bronze and cast iron...the cast iron was the cut off ''SPRUES'' from castings done in the workshop foundry...I intend to give them a try after first giving them a good going over with an angle grinder...what do you guys think?

They could be a grat source of cast iron for pistons and the like for small engines...
Are they good quality under the skin? How big are they?

kellswaterri:

Hi Chuck, some about the size of a large orange, some of apple size, they all have an attached leg of 3/4'' diam.I will be giving them a going over with the angle grinder before I try to cut them...heres hoping :noidea:

I think that they will be absolutely useless, you should immediately package them up and send them to me for safe disposal  :Lol: :Lol: :Lol:

Sprues, being the connection of the casting to the outside world, will be the first bits to solidify so there is a chance that they have chilled and will be hard but otherwise they should be the same quality as the rest of the casting except perhaps for some dross on the surface exposed to the air.  What a nice gift. 
Cheers
