You are probably way ahead just buying a pole pig.  If you use sheet metal
the silicon content is too low and it won't work the best.  Also, consider
the fact you have to literally paint each single strip with insulating
varnish to prevent massive eddy current losses.

Building you own can be done but it is a tremendous waste of valuable time
considering pigs are available for under $150.
