Homemade Model B to D Conversion?
Posted: Sat May 30, 2020 12:07 pm
I received this bed-plate from Jerry B. to salvage for some parts. At first glance with no end-gate it appears to be an Edison Home Model D.
But after soaked and taken apart one notices that this had an end-gate and it was hacked off.
In addition there it has a 2/4 minute conversion. However its not like any other conversion I've seen. The feed screw thrust collar seems to have been cut and moved further down the shaft to act as a journal and a thin metal shim was in place around the remaining portion of the collar acting as a bearing, and all located under the center support.
It did spin freely and stayed in place once I freed it up, so I suspect it may have worked.
Anyone care to comment? Have you seen this before?
Also, can someone please add a photo of the correct thrust collar for a Home A/B Conversion. I'd like to use the good parts of this to convert a B machine that I have so I'll need the correct collar.
Thanks!
Phil
