Hi folks....
over the past year or so I've been collecting some motorising upgrades for my Myford ML7B.... Basically the original (1948) 1/3 HP resilient mount motor was on it's last legs, or at least the resilient mount was, plus one of the countershaft bearings has been dodgy since I got it (previous owner had a blocked oil-nipple adn didn't do anything about it), and I've never been happy about being sprayed by swarf, especially when working on brass or cast iron......
New bits fitted:
3-phase 3/4 HP motor with a secondhand Hitatchi J100 inverter.
Secondhand countershaft assembly with clutch
Ex-school motorising arm with industrial chuckguard fitted to it.....
All the bits came from ebay, the motor and inverter cost me a total of fifty UKP including postage, the motorising arm was only about 40 quid inc postage (that chuckguard is enormous) and the clutch kit was about a hundred or so I guess....
just finished the install and now I have a nice quiet unvibrating, powerful, properly tensioned ML7...
Wish I'd done it back when I had all the bits sorted out now........
I do now have soem spare parts...
1 a 1948 era Brook Crompton 1/3HP motor. The bearings are fine as far as I can tell, but the resilient mount rubbers are sh*gged and will need replacing. Useful if you like period stuff I guess and built like a tank...
2 a 1948 Myford ML7 motorising arm assembly with countershaft tensioner and motor plate.
3 a 1948 Myford ML7 countershaft set, the pulley end journal is the one that was allowed to run dry by the previous owner and now it takes twice as much lube as the other one..... it works but it aint pretty and I'd get it sorted out before using it but it still works ... complete with pulleys.
I'd swap any of the above items for a 3P + E surface-mounting socket and a cable plug for same plus a "Stop" switch (twist to disengage) mounted in a box....
I'm off to take some photos so I'll try to get some of those bits.......
