Colombo spindle dust boot?

I'm wondering if there's a good dust boot available to fit a 5HP Colombo spindle?
I've been using a self-built unit for years that was marginally effective but I finally broke it and need to replace...any ideas?
Thanks - Boyd

Thanks Don, I've sent them an email inquiring about fitment.... given the gantry geometry on these machines I'm thinking an extra long plenum may be required. My machine is an older PRT Alpha.

Yup, just as I suspected...The Kent dust shoe doesn't play well with my older style gantry and a Colombo.

Design and build a better one.

Thanks Dave, I'll do that.
