Kind offer but did you not say it was 1/4 Hp.
Would take you up at a stroke but not sure if it would help . My problem only shows when I start cutting,. On the bench mine runs like a sewing machine

Will see what suppliers say tomorrow. Failing that it is maybe a 3 phase option .
Or someone told me you might be able to point me to an economic servo set up. Any I have seen seem well beyond my DIY budget
