    Talking Dual yokes completed

    Well I think I've jagged it. After unsuccessfully trying to manufacture yoke bearings using plumbing fittings I lashed out and bought pillow block bearings to do the job properly and the result is more than pleasing. Dual yokes move in unison with absolutely no play due to the bearings and simple wire trace connection between the two (idea pinched from Gwyn).

    Here are a few pix with more on my website and in the photo gallery here. I've also made a short video of them in action which you'll find on my website.

    Gad it's great when it comes together!

    Ken.

    Ken, this is brilliant. Thank you for sharing the photos, as it's a really cool idea and I can see that it's the simplicity that makes it work so well.

    Thanks!

    This is just what I have been looking for. I have been gathering up parts (aluminum tube, threaded rod, Aluminimum angle pieces, springs, etc. to build my own yoke to replace my CH yoke which I really dont like. I have been researching the various builds out there and this by far is the most simple and elegant design I have seen. Using the pillow bearings in conjunction with drawer slides is ingenious. It can easily be adapted to a single yoke setup. Thanks a bunch for sharing. Now I just have to find where to get those pillow blocks.

    Try a good automotive parts store or a tractor parts store. One of them will have them.

    If you can't find them locally, Enco and MSC Industrial supply are possibilities.

    Scott, glad to be of help. That's what this place is all about. I can give you the online address of the place I bought my bearings but they're in Brisbane so shipping my be costly, however you'll get them at any engineering supplier. Take care though as there are g-zillion sizes and types. I bought 25.4mm inside diameter as appose to 25mm due to having 1" tubing and they were a perfect fit. Had I got 25mm they would have been too small. Obviously if you can take your tube into them and try before you buy the better. Good luck.

    Dieter, explain more about the trimming system?

    Ken.
