Hi Rob
Yes SB used an over center link with an adjustable coupling with a
right and left hand thread so you could shorten or lengthen the link
to the countershaft. With the arm and the adjustable link you could
adjust the belt tension as well as loosen it for changing spindle
speeds or left lose when not in use. SB mounted this arm on the head
stock by a pin that went through the head stock casting just under
the front back gear shaft bushing. I am not sure there is room to
do this on a Dalton head stock but I have set some of these units up
using a gas strut in place of the link. I have been thinking about
building a really good back bench mount countershaft for Dalton
owners but have not had time yet. Hell I can't seem to find time to
complete the thread dials yet. I have one more project in my shop
and as soon as it is completed and shipped I will have time to
complete them.

Thanks for that information. Are there any of these units with
away to relax the tension when not in use?
Thanks
Rob
