I have read the posts that suggest that a straight shaft for the Excal is much easier on the bod but when I looked at Anderson's shafts for $120.00, it certainly isn't easy on the wallet. Com'on! $7.00 worth of materials and a few holes? I'm going to build my own. Only question is where to get the material. Looks like 7/8 inch tubing and it would be nice to get a twist lock. Anyone know a material source in the Minnesota area or can I find it online somewhere? I know boating supply places might have it if they build bimini tops but none around southern Minnesota.
