29k15 Shuttle Rack and base plate DXF files

[29k15engine]

After much work these are the DXF files required to cut correctly profiled shuttle gears for the 29k15 Singer Patcher, although I have extensively tested these on my machine I take no responsibility that these fir yours, they are however ovet 6 month work and are as accurate as i can make.

These can be cut with an EDM wire erosion machine from a suitable steel (Hardened tool Steel)

I will provide side profile drawings for the depth to cut the shuttle gear after the EDM has cut the gear profile.

thickness for pieces before being cut on EDM, surface grind to these sizes,
