The cheaper spiral one is from Taiwan and the Helical one is made by Byrd. I
checked on ordering one for my 50's Rockwell Crescent 4 knife jointer. The
Taiwanese ones fir the standard models currently available. The Helical one
comes in two models, the standard one and then they make one for the older
Rockwell and Delta machines. Byrd is very nice to deal with. Sunhill on the
other hand tried to be helpful but didn't really listen to what I was asking
and I lost a lot of time.

I was browsing the Sunhill Machinery website the other day and I noticed
this:

http://www.sunhillmachinery.com/Spir...Conversion.htm

It seems to be a conversion kit to convert my Jet (and other brands) of 6"
and 8" jointers from standard blades to either a spiral or helical
cutterhead. What I want to know is has anyone tried one of these and what
do they think about it? The helical looks more like what Grizzly sells on
their higher end models, but the 6" spiral jointer cutterhead is only $150
upgrade (which is easier to sell to the SWMBO than the $320 helical
cutterhead conversion kit).

Thoughts?

IIRC Steve Knight of Knight Tool Works just installed a helical on his
jointer. Do a google search on his name and it should come up. This was a
recent thread within the last month. I think he went with a different
vendor.
