The Myford ML7 refurbishment and rebuild is finished!!!


Well I am pleased to say the Myford ML7 lathe refurbishment and rebuild has been completed! My first piece of metal bar has been turned (see photo) successfully if nervously.

There are a few items still to be done but other than bolting the lathe down, they are just adjustments. Such as the main motor belt guard is catching the large pulley somewhere and the gear guard won’t go on because of the top filling/storage cabinet doesn’t give enough clearance when the gears are fitted.

I also have decided to make a new steel tool post and holder system as I have on my other lathe and two new gear studs as fitted to my ML10 and later ML7 lathes. Then there are the drawers and front door for the bench below and that should be about it. None of which stops me from using the lathe however the next job will be to bolt the lathe down and use the test procedure to make sure the lathe turns true before any serious work is started or done. However I must admit to a little smile at the smooth cutting of the aluminum……….

Today started with the fitting of the parts recently arrived from Myford (although some will have to go back as they are not correct). Starting with the fitting of the saddle and using the clever shims that cost around £5 each! Malcolm, from Myford told me when I ordered the parts that the shims come apart at around 0.015” a layer. They are separated by flicking the edge of the shim and then the layer pulled off. To shim the saddle you start at the back right hand side and using a dial indicator measure how much movement you get if trying to lift the saddle. The aim is to get under 0.0015” movement all around. The first attempt saw the saddle fit within the tolerance level set, however when trying to move the saddle the length of the available lathe bed, it became stiff when moving toward the tailstock. My immediate thought was the bed being worn more than I thought. Before making any further adjustments I remembered that I had only adjusted the saddle gib strip approximately and after a proper adjustment the saddle moved freely across its range with only about 0.001” movement of the saddle on the right hand front side.

With the saddle adjustment made the next job was to adjust the top slide and cross slide and then with a little trepidation I chucked some bar and made the cuts. I have enjoyed the refurbishment although I will be glad to get back to making the Seal 4 cylinder engine but that may have to wait for a few days since I will be helping my brother, Steve, with sorting our fishing boat out after all the smoke and oil that escaped from the engine after our last trip!

About Mike Freeman

Hello, my name is Mike Freeman and I am a retired Chief Fire Officer from the United Kingdom with a keen interest in model engineering, silver caddy spoons and sea fishing. I live in the pretty fishing port of Brixham, South Devon, in the United Kingdom. I am a sufferer of degenerative osteoarthritis, which impacts on the amount of time I can spend in the workshop, and is the reason why you will see seats and a stool in some of the photo's. I have only recently added the above sentence after a discussion with one of my Doctor's from the excellent pain clinic, based in Torbay. This does affect concentration one of the reasons why I double then re-double my measurements and set ups. Before completing nearly 30 years of public service I and my wife Sandy, owned and ran, a small restaurant in Okehampton Devon. Prior to marriage I worked for my father in his various businesses, in the early days these were garages, which he bought in a run down state, then built them up before moving on, to start again. I took every opportunity in those early days, to work in his workshop's learning 'on the job' rather than as an apprentice. This, I suspect, is the reason why my building various model's in the early days, turned into model engineering, when funds allowed the required equipment to be bought. My workshop comprises one half of a detached double garage. It has a stud wall separating the two halves and unusually perhaps, its own shower/toilet/washbasin compartment! (the true reason for buying the bungalow - don't tell the wife!!!) It is fully insulated with a ceiling and fluorescent lighting supplementing the one window. Several double electrical sockets are dotted around in relevant positions. Equipment consists of 2 lathes (1 Myford ML 10 and 1 Chinese variable speed motor with etched glass DRO's), 1 milling machine (RF25 far East) floor standing pillar drill, Proxxon bandsaw, Warco bandsaw, 6" wire brush and polishing mop motor, 6" coarse and fine grinder, Proxxon mini drill, various benches and an engineers vice. I have just acquired a third lathe, a Myford ML7 which I am at present evaluating so I can decide which of the Myford's I will keep. I have only just bought the Chinese lathe and had it fitted with DRO's prior to delivery. And what a bonus they are! So good in fact that I decided to buy another set for the Milling machine. Whilst my engineering experience can only be described as limited, I find the use of DRO's has affected my accuracy levels which have improved tremendously (although that's not saying much!) and would recommend their fitting to any model engineer. Prior to retirement I built for my son's 17th birthday a Locost car. This was a tremendous project and a great feeling when it passed its test. The book it was based on suggests it can be built for £250. Ours was nothing special in the sense of all new parts but still cost about £900 to build!
