I have a wood frame boring machine (no name on it).
The wood frame is in good shape but the rails that the drill arbor slides up and down have popped two screws loose and I tried gluing in small slivers of wood in but the screws have worked loose again.
The rails are also about 3/16 too close together. This allows a lot of movement side to side of the drill arbor.
Could shrinkage over the years cause this?

I am contemplating rebuilding the frame to accomodate the old hardware. Any body else done this?

Thanks
Bob
