Rear bearings are shot! DickG

I don’t understand what you are talking about. What pressure? Do you mean you have moved the spindle forward by adjusting the rear bearing assembly forward? If so the spindle should have loosened. Forget looking at videos, get a copy of the Myford S7 manual and study the drawings. adjustment is...

The TriLever is still just an ML7 with a system of selecting from three belts without having to manually change the belt from one pair of pulleys to one of the other two sets. It doesn’t have all the other improvements that the S7 has. You could fit a complete S7 saddle, cross slide and top...

Myford Super7 is a much better machine than the ML7. Better spindle bearings, 60 tooth bull wheel is better for dividing, longer cross slide, better top slide mounting system, clutch as standard, better range of speeds, faster top speed. Fit a 1 HP 3-phase motor driven from an inverter gives you...

My Myford S7B has NuT link belts for both belts. Runs smoother and quieter than the original Vee belts. As the lathe now has a 1HP 3phase 1400RPM motor with an inverter I have managed to run the lathe up to around 4,500RPM with no problems. The rear spindle bearings have been replaced with a...

As I have an electronics background I often need to drill 0.8mm holes in PCBs. As an aside a 1mm drill to me is big! Many years ago I set out to build a Quorn. This involved a series of tools to build tools to build tools. One of these was a tapping & staking tool and I also made the precision...

I often need to drill a 0.010” dia hole in silver steel. This is for the anvils used in my “Graskop” Rivet Tool. I do have an advantage in that I can use the tool to centre pop the blank anvil. I can drill with very small drills in my Myford S7. This has a rack feed tailstock and a 1HP 3-phase...

Hemingway sell round belting by the metre. Joined by the ‘hot knife’ method. They do include a drawing of an easily made jig that ensures a good joint properly aligned. Alternatively, why not just search eBay, or your local ‘bearing’ stockist, for a suitable O ring?

Graham, Not such small town, although we still say we are going to the village. I'm in Dewlands Road, opposite the common. What motorbike do you ride? I have a 1977 Honda 400/4 that I have had from new.

It’s a fairly simple job to modify an early Myford 7 series lathe from narrow guide to wide guide running on the back shear. I wrote about this in Model Engineer way back in around 1973. My mod was simpler and easier to do do than previous ones. Shortly after Myford changed to the wide guide. I...

I have a 1A which I bought from a dealer for scrap value as it was minus the pitman arm. It cost me me 10 GBP plus the diesel to collect from 125 miles away. I fabricated a new pitman arm and modified the bottom bearing to allow the arm to slide on a bronze block. This followed a mod that a...

Super7 without a clutch? Didn't it always have a clutch? ML7 has no clutch, but could be added as an optional extra. When you replace the headstock belt go for a NuTee Link belt. Saves all the hassle of removing the spindle - easy on an ML7 but a nightmare on a Super7. How do the belts on a...

I am intrigued by the persistent use of the word "cycle" instead of "stroke". A two-cycle engine would only run for two revolutions if it was a two-stroke or four revolutions if it was a four-stroke. A cycle is the complete "suck-squeeze-bang-blow". A 2-stroke engine does a complete cycle in...

I don't know about transferring an S7 onto an ML7 bed. One thing that won't transfer is the serial number stamped on the bed! I don't understand why you want to change to a short bed. Is it because the long bed won'f fit on your stand? If that's the problem wouldn't it be easier and cheaper to...

With the earlier S7B I had it was easy to adjust the rear bearings and then set the front bearing clearance. I had no problems with running at top speed or putting a large drill into steel. With the later model I found it impossible to set the rear bearings and they wouldn't take any end thrust...

I ought to remember when Myford changed over from the narrow guide system. Way back in the 1960s I had an imperial Super7B which had come out of industry. The bed was worn at the headstock end. I had Myford regrind it but that didn't get rid of the serious design fault with the lopsided front...

An electronic boiler water level unit is very simple to make - even if you have no electronic knowledge. Hundreds of them are in use over here in 16mm and G1 steam locos. There are versions for one or two electrodes and the electrodes are quite straightforward turning exercises. DickG
