    I need some advice on my traction loss. I had ordered 3 25:1 worm gear motors for my project. I have my 2DOF's running great so I decided to tackle the traction loss.

    I have concerns that my 25:1 motor - as my dad used to say - doesn't have enough lead in it's pencil! I am using a 12" lazy susan pivot up front. I can swing my unit by hand, but you can def. tell it has a seat, tv, and shelf on top of it.

    You can see my motor mount plan in this pic. I know my lever is too long in the picture and I have already tried a shortened length as well. I am connecting under both rear corners with cable hooking to a pivot on the lever.

    Basically, I have 2 questions. First, what size/type of motors do any traction loss users have in place. Second, does anyone see a design flaw in this setup?

    Thanks,
    Steve

    Game plugins that have Traction loss available are normally connected via Extra 1 or 2. I cannot comment on your design as I used a chain drive.

    @CoachKalk why don't you us a timing belt pulley, two guiding pulleys and mount the belt underneath your seat assembly. This has a few advantages; no real danger any body parts are getting caught; it looks cleaner; it makes little mechanical noise and it is easy to maintain. To tension the belt you need to either fabricate something that will move the driving pulley away from the two other assisting pulleys or tighten the belt on one side when installing. Below a quick sketch.

    @Martin van Hagen - thank you for that drawing. The only pot for this would be the Hall effect type that has no rotational limit - correct? I like the potential this design has for increased travel. I have changed lever length and attachment points so it is working, just not very much travel side to side.

    Depending on the torque required to move your seat you could install a bigger timing pulley or as you mentioned yourself multi- turn pot would do the business. Remember that half the total travel/circumference of your pully= turns required to move one direction.
