I am debating whether to purchase one, but am not sure if the adapter will fit on my machine, because the screws are diagonal when facing the machine, rather than aligned length wise. Has anyone every installed a Wise on a Silent Partner e.Stringer? I called TW and Herb, and neither was able to tell me definitively. Herb noted that I might need to drill a hole in the adapter. If that's the case, then I will pass since I don't have any tools that will drill through iron. Thanks in advance for any advice!
