I get the feeling that the stems for my bases are over time going to crack. Is there an issue with replacing them with brass rod and magnets. The current tournament rules say
Ship bases cannot be modified to alter their size or shape. Weight may be added to a ship base if it doesnot alter the size or shape of the base.
Which is not exactly explicit either way. The base size is definitely not altered.
--------------------
If I do it I think the best way is to find some washers that fit the brass rod precisely, Then Araldite them to the underside of the base. This I feel should stop the base cracking when I'm drilling through, and give me even more support for the rods. Then fill the rest of the base with Silicon and smooth. Then I should be able to glue a magnet into the washer, into the ship and onto either end of the rod to allow hot swapping. It would also allow me to have extra long stems for when I need to raise the ship to stop bumping.
Does this all sound reasonable?
