I use the
"Original Length•Master" ~ 01.AUG.09, I replaced the original washers with "
fender-washers" because the regular washers were indenting the wood and causing uneven tighting. The fender-washer has a bigger foot print and diffuse the pressure over more area and enabling a tighter grip. I don't have the new
Length-Master to know what material was used for it. I would image something light and the same issue I experienced would occur as it did on the 1st version. Fender-washers are worth the investment, less than a $1(US).
