<p>Today I started by looking at the leadscrew and how I would make the bushes. I am still undecided as to what to do at the tailstock end but the headstock end requires a new shaft made and the bearings fitted to the aluminum housing are quite thick. Far more so than those supplied by Myford for the countershaft. Those are oilite bushes and I am not sure what those in the leadscrew are. I could ream them to a convenient size and make the shaft to fit or I could make new bushes and bore them to the correct shaft size. I must admit that I am leaning towards new bushes and the correct size shaft.</p>
<p>Putting this to one side I carried on wiring up the motor, inverter and remote control box to Dave's directions. I managed to get to just one query when reading my scribble. So a call was put in to <a href="http://cgi3.ebay.co.uk/ws/eBayISAPI.dll?ViewUserPage&amp;userid=drives_direct_nottingham">Drives Direct,</a> Nottingham to check the wiring was correct before switching on and dealing with the programming of the Inverter.</p>
<p>I must compliment Dave on both his knowledge and ability to get the information across. After clearing up the wire I couldn't read on my scribble pad the motor was switched on and whilst nothing happened I was told by Dave that that in fact was a good sign!</p>
<p>After step by step directions by Dave the motor was not only running silently, but the variable control was great. I am very pleased with the set up I have got even if I spent a little more than I planned for. The control and engine of this lathe will certainly not be its weak point.</p>
<p>Dave was extremely busy at the time of my wiring up, giving help to other customers BUT they never failed to call back, ever. Many other firms could benefit from there example. So a public thank you Dave.</p>
<p>The next task was to plan where the inverter and remote control box would be positioned. The inverter was quickly sorted out and screwed the the wall by the power socket outlet.</p>
<p><img title="New inverter fixed in position" src="http://i353.photobucket.com/albums/r379/brixham-engineer/Myford%20refurbishment/myfordrefurb27012007001.jpg" alt="New inverter fixed in position" width="350" height="440" /></p>
<p>The control box is a little more complicated as until the lathe is working properly its a little difficult to decide on its final position so I placed a clamp on the bench in the place I think will be ok, but I shall make a fixture to hold it and finally fix after a little practical experience shows me the best operating place.</p>

<p>The next task I have started is to make the pulley fit the shaft and cut the keyway so hopefully tomorrow the pulley will be ready to be fitted to the new motors shaft.</p>
