Whiteside trimmer shafts & woodturningz cutters?

[LagniappeRob]

Anyone know if the Woodturningz cutter heads would fit the whiteside trimmer shafts? Woodturningz has them on sale (ending tomorrow I think) for $6.75 and $7.75 as opposed to several bucks more each. I was wondering if they would match up?

OR

I think CSUSA also has their Artisan ones that has more sizes (but not as many as Whiteside), would those work either?

When I called to place my order, I asked about if the heads would fit others. They KNOW they do not fit the PSI shafts, but they aren't sure about the Whiteside ones. I picked up a couple of extras above filling out the heads on the set they have on sale, and will be trying it out.
