7227 forum posts 21 photos | When I managed to crack the Cross Slide on my Myford, I was lucky. A colleague had been Foreman in the Toolroom. He very kindly had one made "to pattern" ( minus crack ). So it may be possible to have a new Cross Slide made, rather than trying to tart up a badly worn one. With regard to screwcutting, I do not go looking to do it, but when forced to do it, I proceed gently and slowly.. The adaptor that I made was for a ML4. Fortunately, a friend loaned me a 7/8 BSW tap for the internal thread. The external one I had to cut, but could use a "standard" Myford fitting chuck as a gauge, to check progress as work progressed.

9 forum posts 16 photos | It's certainly handy to know people that have those skills to reproduce items like that. I have sent a couple of Emails off to engineering companies locally to see if they would look at making a unit and a Coventry based company they say they deal with piston spraying so I thought they might be used to the precision required that does metal spraying. I have already learned that from here so thank you very much I didn't know that was possible before now. I am going to give the measuring the runout a go first and then once I know how worn it is I will then make the decision to letting someone else take up the reins and me getting a different lathe or continue to resurrect this one, although I do want to keep this one if possible. There's no rush because it's only for learning the ropes of metal turning. I imagine the Tap would be ideal for a loan item not any everyday thread of that size. I must admit I have had a sneaky peak at Boxford lathes too. it seems everyone needs 2 lathes to mend the other one I doubt I am the only one that has talked themself into that theory on here Hopper Thanks

7227 forum posts 21 photos | The centre lathe is the only machine tool capable of reproducing itself. When I managed to mangle the gear that engages with the rack to traverse the Saddle. Using the Cross Slide and Top Slide with manual feed, I was able make up a new blank to cut a replacement gear. Fortunately, the length required was less than the travel of the Top Slide. But, having become lazy, I did miss the power feeds! But that gave an incentive to make the replacement gear and reassemble everything. Howard |
