|Thread: Choice of lathe|
I agree that you could just paint it and sell it on for a quick buck but the design of the Myford is such that they can be refurbished back to as new geometry fairly easily.
I appreciate that if you are not an engineer by trade or you don’t have access to the necessary machinery it would be an issue but it’s the quality of the parts and castings that I believe has maintained the value of the Myfords over the years.
I have nothing against the eastern machines, I have run a Taiwanese Hardinge (Bridgeport) vmc for 7 years and it's not missed a beat, and it cost 3K less in 2005 than an Interact 4 cost in 1986, BUT will it last a long? I'm in a tool room and we look after our m/c's so only time will tell.
I personally feel that the Myfords came from a time when quality was paramount and Britain lead the way .
I love the old Myford brand, I don’t think they are overpriced but they were over engineered, they were industrial quality.
I have a long bed super 7 and use a ML7 at work regularly, but as you say buying the right one is an issue but at least you can refurbish them.
The bargains are on the real auction sites, take a look at this super 7 **LINK** I bet the next time this comes up for sale it looks like new!
|Thread: Drawing Projections|
Sorry guys, didn’t mean to cause any upset but if it helps someone to have a visualisation method to help them why not?
Third angle –up the bowl, Flemings left and right hand rule for motors or generators, rhymes for remembering trig or resistor colour codes etc.
If engineering is someone’s hobby he needs confidence in his own ability to question a poor drawing, after all material is expensive and hobbies are supposed to be fun!

The cone is a solid, when I served my apprenticeship, the old guy that taught us used a glass bowl for his examples. The bowl was upside down for first angle and right way up for third angle.
Even now some thirty years on the first thing we do is take a marker pen and our blocks of metal and you can look around the shop and see others mouthing the words `up the bowl’ or `over the bowl’ as they mark out the features.
Third angle is the most common now, I would suggest that you get your material and get use to physically making the move from plan view to end view by making the move up the edge of the (imaginary) bowl. As John said it’s a rolling movement through 90 degrees.
If you are machining features that are up at compound angles it really helps to have visual aids.
As JA stated, old school drawings made on a board followed the rules. Drawings made on CAD by young lads that have not served time in a tool room or even seen a machine could be anywhere………..does that sound cynical?
|Thread: Myford Super 7 move|
I’m new to this forum and never been involved with any forums before, so please be gentle with me.
Engineering is both my job and hobby so I’m fairly passionate about it. I have just built a small workshop at the bottom of the garden and had to move my tools from the garage at the front of the house to the (hopefully) more secure back garden.
As I had to completely strip my Super 7 down in order to carry it, I used the opportunity to clean it and replace the worn belts.
I have posted some photos in an album, not the best off my phone but I felt the need to share them.
I have owned this for about 25 years, I brought it from a major department store in Birmingham city centre when they closed their maintenance department, it was covered in rags and brass swalf but like new.
I have always looked after it as I do the machines that I work in my job, it is used regularly and for long periods but always well oiled.
As I set about cleaning and rebuilding the machine I could not help but feel a sense of pride, the bearing surfaces are like new, the scrapping marks are still visible on the main bearing. I have always made a paste from mixing two Rocol products for the open gears and once clean they too are like new.
I love the old Myford brand, I use an old ML7 and Myford Uni-grinder at work and also own a Myford planer/thicknesser, It was everything that was great about British engineering…..it was done right.
I replaced the oil wick in the main bearing as a matter of course and both belts with new Power twists, the resilient mounted motor was the only problem.
The bushes are no longer available so I had to mould them in RTV silicon rubber.
If anyone has the same problem with the mounts just shout, it’s a simple mould but it’s yours.
Proud to be British
