Finaly got my anchors working using a modified servo and two sewing machine spools, i tried scale chain but it was open link type and was to weak
for the job on the winch i made drums out of acetal/delrin drilled for a spring out of a ball point pen and a small ball bearing to locate on the holes in the sides of the spools,the spring tension can be adjusted using a grub screw,i have them set so under slight tension they ratchet i ended up using brass decorative chain from B&Q in the end not scale but it will suffice for now
, they drop to about 800mm the only trouble now is the anchors dont always seat the same way when hauled in
, they are made of white metal the type with the pivoting claw i may remake them in brass and weight the opposite end to the claw to make sure they retract properly
