    Baldwin used to loan a tool for setting the string height on the accu-adjust hitch pin. I need to remove a set of bass strings on a Baldwin R.  Anyone know anything about this? Or have a good way of setting the string height.
    Thanks,
    Stewart Freedman

    You can make your own guide. Take a 1/2" thin piece of wood, 1" x 4", and cut a notch in one end. Then thin the wedge to where it fits under the loop on the hitch pin. (All of them are set at the same height). After you've strung the bass section, before you pull up the tension, put the wedge under each loop and adjust accordingly.

    Search past journals that carry ads showing the tool. Not sure if it was loaned or you could get one free. My understanding is that the accu-just method helped ad crown to the soundboard. Maybe someone can describe the design . I have only seen a few pianos with this type of system The hitch pin loop does not touch the plate . I think I have the instructions for this system and how to deal with it.

    Accu-Just is about adjusting downbearing at the bridge.  Look for machinist tools to measure and replicate proper heights.  You may also find guage tools sold by Infinity Tools,  inch and metric useful.

    Stewart,

    Sorry to be slow in replying but it's been a really busy week. I've restrung 2 Baldwin Accu-just grands so far this year and I'm about to do a third. Adjusting the downbearing is pretty easy once you get the hang of it. A modified C clamp with a notch cut in the end and the end ground off fairly flat works great as a string raising tool and is very similar to the factory tool. I also coated the body with plasti-dip to minimize any chance of dinging the plate finish.

    For setting bearing I use a modified Lowell downbearing gage. The spirit level got broken on mine some years ago so I replaced it with a digital angle gage attached with zip ties to the top of the gage. This arrangement is super easy to read and zeros out immediately for fast measurements.

    I'm also placing in the library a set of instructions from Baldwin for setting bearing on this system with specific notes for each model as well as their instructions on setting plate height with their system.
    Best regards and I hope this helps you and anyone else jumping in.
    Allan

    I'm sure there's a beter way to link to the file in the library but hopefully this will take you there as well.

    Thank you, brother. I figure we're all in this together! There's more to learn every day. 

    Be well and I'll get an update on your scaling program ordered soonest as it's still my favorite for the task and I have a job coming up soon where I'll need it.

    Thanks to all for the responses. Allan, a special thanks for the tool pics and service manual from Baldwin.  This is the detail I need to do the job.  Much appreciated.
