Thread: Boring a cylinder
18/11/2017 23:18:17
If the bore is smaller at the end closest to the headstock then perhaps the tool bit has been pushed back into the hole in the boring bar.

In other words the grub screw or bolt clamping it has worked loose.
Thread: How Did Lawrence Sparey Make It Work?
16/11/2017 11:02:41
Somehow I think his sales are safe!
16/11/2017 10:47:44
It's spreading...the Sparey grinding spindle debate has now started on the Drummond Yahoo Group!
15/11/2017 16:51:43
To be absolutely clear I am neither disparaging nor laughing at Sparey and his ilk.
15/11/2017 13:25:23
That's also a good book.
15/11/2017 09:16:04
I think he'd laugh too. And I think he'd be gratified to know his book was still useful and still discussed.

I'm sure he'd be the first to embrace modern methods and tooling.

True enough. On the choosing a lathe front though I wish I could get the Harrison L5 that's in my copy for the money he is talking about then!
14/11/2017 15:10:03
Hopelessly out of date in places...well maybe. For me it's the little nuggets of information that make it worthwhile.

One that springs to mind is using old bearing outer races as parallels on the faceplate or mill table.
14/11/2017 08:13:20
Agreed Hopper.
14/11/2017 01:28:54
Indeed. As I say I think it's a great book and this doesn't detract from it for me.

There are lots of nice pictures of Drummonds in it. These inspire me to take the 3 plastic crates full of bits that purport to be a Drummond B type that are currently languishing in my workshop and get on and restore the poor thing.

So after all this, the answer to the question posed in the original post is - He didn't.

I don't care though. It's still a great book.
13/11/2017 19:58:47
Thanks for that! It's a rum design and no mistake.
13/11/2017 13:08:45
All of that above may well be the case.

There's still no driving feature.
13/11/2017 11:55:54
Glad someone said it. It's a great book full of sage wisdom. But that drawing is nonsense.
13/11/2017 11:34:13
I've been looking at that photo in the book and thanks for posting it so others can see. There is no positive driving feature on the shaft. I agree with Ian in the drawing in my book it looks like the little undercut has the pulley metal in it. Can't be right.

Thread: Barely can spell 'lathe', looking to get into the hobby

There is a guy with a channel on You Tube. His name is John Mills, nickname Doubleboost. He puts out a machining or welding video every Sunday eve called Sunday Night Night Cap.

He's been doing this for 3 years ish, so plenty to watch. He is really down to earth and very highly skilled, but with that rare ability to pass knowledge on without being condescending.

You'll learn more from watching a few of his videos than from reading a dozen magazines.

Magazine beginners articles are usually thinly veiled adverts. Avoid unless you want to learn how to unbox something really well.

Neil if you solve the mystery you could write it up for Mew!?
12/11/2017 21:41:35
That aside, how does the pulley drive the shaft? There is no key or driving feature.
12/11/2017 21:23:02
It's on p84 in my copy. I can't see where the driving feature is between the pulley and the shaft.

Also agree that if tightened the nut will just nip the bearings up. If partially threaded the pulley would not set endfloat on the taper plain bearing because it would still just pull the shoulder up against the front of the forward most roller bearing. As drawn, unless I'm missing something, it won't do anything.

Thread: How long does it take you to make stuff?
12/11/2017 00:22:45
I spend quite a lot of time thinking about the sequence of machining operations, and then still go and make a right fiddlers elbow out of it.
