Rhodes Mfg Company made a small shaper that could be converted into a slotter. Or you could buy it configured as a slotter. Last year one was donated to the Tuckahoe Steam and Gas Association. ( http://www.tuckahoesteam.org/ ). I have scanned the literature that we have and have posted it in the drop box to share with others. Plus, if anyone has more literature, or the pages missing from the catalog we have, we would appreciate a copy. I’ll post before and after pictures when we complete the restoration. You can see our restoration progress on the CAMS web site - http://www.cams-club.org/ Vince Iorio
