Myford Wide Guide: where does saddle contact bed exactly?

[NJHParticipant @njh]

Well Neil you may well be right with the bargain price of DSGs BUT you would need a VERY BIG shed to put them in!

Not quite the "Rolls Royce of Lathes" then but still doing a good job for a 60-year-old machine I reckon.

.

May I just ask, Hopper … has anyone [apart from perhaps your good self] ever implied that Myford might be considered the "Rolls Royce of Lathes" ?

That acolade is, I believe, usually reserved for 'Dean Smith & Grace' machines.

It seems to pop up in conversation and on forums, usually in the context of the Ye Olde British vs New Chinese lathe debate.  The fellow who sold me the ML7 mentioned it I'm sure. Turned out to be the most clapped out Rolls Royce  ever though, having been treated more like a farmer's Land Rover and bashed to bits over many years.

Actually Rolls Royce made a series of small precision watchmaker-sized lathes so I guess in reality those would be the Rolls Royce of lathes. .

…

The beds were milled on their vertical shears to promote retention of oil due to the curved shape and depth of the surface finish pattern.

Makes sense. Another example of clever design reducing production costs while improving the product. There really is quite a bit to these old lathes when you look at them closely.

1. I have put on my flack jacket.

2. The Myford was built down to a price. "Ok for lunch" but not banquet fare, Homage to the late Leslie Walford one Australia's great designers…. his specification to me when asking for a textile that was not too pretentious.. British trained too,

3. The DSG was built up to a supreme standard. As were a number of other makes of "tool room" standard lathes.

4. I am entering my bomb shelter!

… no bombing from here, John

To my mind; the beauty of the Myford ML7 and its offspring is that they were honestly built, in a way that their users were capable of understanding and appreciating. … Rather like we admire the skill that's gone into a prize-winning amateur's tool-making more than something 'incredible'.

Most of the lathes in the tool room machine shop where I served my apprenticeship were DSGs. They were just a lathe to me. The went round and round. They cut metal. They did what a lathe was supposed to do. I thought all lathes were like that.

Maybe that's why I was so surprised at some of the Myford's design shortcuts.

My Harrison M250 has similar machining on the flat mating faces of the cross slide and saddle.

 

The machining marks on the saddle are like this. ((((((((((((((((.

Whilst those of the cross slide are like this. ))))))))))))))))).

 

There's no scraping of these surfaces, but the movement is smooth and with no play.

If someone decides to do the 'wide guide' conversion, then it can be useful to employ an adjustable gib strip at the back, as it can be used to 'tune out' any 90 degree facing error that may be present.

Well if eBay prices tell us anything… you can buy three Dean Smith & Grace 13 x 30 Toolroom Centre Lathes for one refurbed S7.

“Dean Smith & Grace 13 x 30 Toolroom Centre Lathe Ex-Lucas Aerospace centre lathe in good condition”

**LINK**

 

Premier machine tools just sold a really nice type 13 x 30 for similar money.

 

The older DSG use the inverted V "american" style beds just like the type 13 in the link. The later 1307 that replaced the type 13 used a flat "english" style bed similar to the myford. I have been told that DSG did this and other changes to reduce costs. I am not sure you can call them the RR of lathes from that point on. Monarch, Schaublin etc etc all kept producing inverted V style. I'd love to own a DSG and I've been thinking about a type 13 or a type 1307 and keep me eye out for one with the specs I want and the accessories. Apart from the advantage (from my point of view) of the 1307 being offered with gap beds I can't see anything about the 1307 that is not inferior or at best no better than the older type 13's in terms of their design and construction.
