Very good! 2 thread pitches. More like a worm gear. Yes, all I needed was 1/4" per offset shown in image. Didn't pay much attention to bottom support but was screwed into marine ply decking there on either side of genset. Could be I bowed it! Probably compressing the rubber cushions on the base of the struts is the reason for so many turns. However, 8 - 1/4 turns is only two thread pitches which is probably less than 1/4 inch.
