today i felt .like makeing the limet of shunt ,markers , i have used my favoiurt cocktail staires, useing the ball end.. a coat off white paint, and a red splash.. drill a simialr sizes hole in the basebord.. and job done ,got abit more off the plastic folage fixed down.. had the wanagro red desile running, but it kept stalling on a point.. multi metter out.. point was ok..checked again, still stalling.. so turned my atention to the little shunter, fliped it over, one skate wasnt showing a conection with the multimeter..and it was stuck, no movement.. so after striping down the motorblock, wheels outy, bullets out, it seems that the moulding that holds the skate, had ,deformed.. i finally got the skate out, the spring, seemed fused to the plastic.. drilled out the moulding, new skate, new spring, rebuild.. test with mulitmeter.. now works fine
