Too much torque?

I have a singer 111g156 that I've been modifying to meet my needs. Eventually I'll switch to a servo motor but for now it's a clutch motor(3450rpm).  I made a speed reducer for it. The motor pulley is a 2in, it drives a 10in pulley that then drops to a 3speed pulley that came off an old craftsman lathe it goes to a matching 3 spd pulley that is mated to the hand wheel on the machine.  I like my speed(s).. Now to the question,  can I create too much torque? I don't want to damage my machine? 

Well I broke down and did it, I bought a servo motor and I am in love. Running it through my homemade speed reducer (3" pulley on servo into an 8" pulley, then a 2" pulley out to the stock handwheel), I can adjust from extremely slow to faster than I'll ever use and it has enough power to cleanly sew 2 layers of 12 oz veg tan cleanly. Now time to play with needle/ thread size. There seems to be several good posts on that topic already in the archives so time to go browse some more. Thank you all for the info/advise/encouragement
