That's great to know. I will measure mine to see what I have. Will now consider going "mini" instead of "shorty".JPG40504 wrote:Greenies and early Goldies(Gilmer drive) had 1 7/8" bench tubes. The 1 3/4" way tubes will fit in a unit that originally had the larger bench tubes, but they will be off set slightly from 'normal'. They can be shimmed so as to achieve 'normal' spacing. Only the 1 3/4" tubes can be used as way tubes.
The bench tubes need to be 3/4" longer than the way tubes.
Later units(Goldie/Poly-v to current)have 1 3/4 tubes for both way and bench tubes.
10E/ER way tubes are the same length and od as current way tubes, but they were twice as thick. Tis a sin to cut 10 E/ER way tubes.They are irreplaceable!
Thanks! Bob
