Just completed recommissioning a 1972 vintage Myford Super 7 I bought last Thursday in excellent original condition. The only issue was with the spindle bearings which had been greased with what looked like Molyslip and were deemed shot when cleaned, and oiled. So my local bearing supplier came to the rescue and obtained suitable alternatives to the R&M LJT25's removed. I've fitted Fag 7205B's from Germany (£38 pair) so should be of suitable quality. The Myford Super 7 has cleaned up very well and has very little wear. The carriage moves freely, without the apron, from chuck to tailstock after the gibs were set up at the chuck end. The front shear has less the .0005 wear in width and thickness when compared to the tailstock end. The machining marks are still visible of the front face of the front shear, and there are only a couple of chuck-drop-dings and a small bruise half way down the bed which was scraped flat. Note to self – make a chuck board.
I've photographed the process of replacing the bearings and set up an album which contains some tips which might be useful when replacing the bearings or just changing a headstock belt on a Super 7 – nothing to be scared about- really.
I'm very pleased with my acquisition which will shortly be replacing my well loved ML7 which has been used to build a Minnie traction engine. I have owned the ML7 since 1969, I was the second owner, it was manufactured in 1964, and from what I gathered, the first owner realised that model engineering was not for him, so he sold up.
The ML7 will be packaged with the Myford cabinet stand, deep-tray and raising blocks from the S7 purchase; (I have a purpose built stand in the workshop for the ML7 ready to receive the S7) the ML7 has a counter-shaft clutch, moveable index-dials, lead-screw hand-wheel and a very useful Cowell rack and pinion feed tailstock, I've also adapted a DRO for the cross-slide which should be possible to move to the S7.
It is the tail-stock attachment I am most attached to, it is brilliant for all drilling, tapping and reaming, being free to move with the progress of the work. I'm toying with swapping the tail-stocks on the machines to retain the Cowell rack and pinion feed tailstock facility. I expect that the S7 will see me out, so potentially devaluing the S7 is not really an issue. What do you think?
