Thread: Product Descriptions (Up to scratch?)
20/01/2020 11:01:07

To their credit, some chuck makers mark the jaws to indicate how far they may safely be used when projecting from the body (by "safely" I mean without undue risk of tooth breakage).

Thread: A good toolpost drill design
20/01/2020 00:04:14

Before I got my QSM I had made a very simple holder to fit the 47mm (?) collar on a drill gun fastened to the cross slide at centre height.

Even simpler, clamp a bar with suitable hole in the toolpost and use this to guide a handheld drill.

My first double post - sorry! What am I doing wrong?

Edited By ega on 13/01/2020 16:29:57

Yes possibly graphite but it looks a bit chunky for that.

re double posts. I have had that when I was a little impatient and did not allow time for the post to load on the forum.

regards

Thanks for the tip!

Thread: Drilling holes using pillar drill - work wobbling

If you have a Bullet-style drill in the target size (ie with pilot nose) you can drill a pilot to match and the Bullet drill will then start cleanly and follow the pilot hole.

Thread: Driving Small Taps
16/01/2020 11:03:16
Posted by David Colwill on 16/01/2020 10:56:51:

I had to tap 1000 holes M3. They were for a grubscrew and were through a 4mm wall. I decided to buy 3 sets (of 3 taps) as I was bound to break some. I used a battery drill to drive them and needless to say didn't break a tap.

I should point out that whilst accuracy was not of concern, I was surprised at how easily a taper tap aligned itself. As I recall there were no rejects.

Regards.

David.

In this kind of job the combined drill/tap is very useful and of course today's drills can be quickly reversed to withdraw the tool.

What was the purpose of pouring swarf on the shaft ?? We know its going to get in there anyway. But at least he made something in the shop. smiley

I thought it might be graphite.

Don't you just need a reducing bush?

Thread: Can anyone recommend a cutting disk for cutting aluminium?
13/01/2020 12:37:26

I think the Project Binky boys on YouTube use an ordinary grinding/cutting disc (I appreciate AA is a different proposition from steel).

Axminster have cutting discs in their sale - cheap enough to try, perhaps.

Thread: Only for Myford lathes

I find the Myford steady a little flimsy, the fingers can move under heavy load parting off 2" bar etc, so will probably make up my own heavy duty steady with brass-tipped 7/16" screws for fingers as I did on my old Drummond.

Edited By Hopper on 13/01/2020 00:24:22

That must have been a very rewarding project.

Had you thought to try a Martin Cleeve-style bush-type steady?

Thus, it's about as good as it gets with a Super 7.

Sounds very nice; did it have a hardened bed?

Eureka:

A propos but OT, I happened to notice the other day that the lathes.co.uk site entry for Selig Sonnenthal Lathes has a picture of the cutter backing-off device which has been discussed here some time ago.

Thread: The Taig/Peatol Lathe - 2nd edition
07/01/2020 00:24:13

Good to know that the print edition is not affected even though the fault is purely cosmetic.

I note that the book is independently published and that there is a significant difference in price between Kindle and print. Does anyone know how the pricing is determined as between author, publisher and amazon?

It seems to me that very often the difference is so small as to discourage the greener choice of digital.

I just "Looked Inside" and notice that something has gone wrong with the initial drop letter (not quite right to a tee!).

It looks very interesting and will no doubt leave me wanting more.

From old Buck and Hickman catalogue:

use em up_edited-1.jpg

I'm afraid this doesn't answer Clive Foster's interesting question.

The reference to "Use-em-up" Type suggests that this was a generic item; in a perfect world such things would not be necessary!

Posted by old mart on 04/01/2020 21:23:35:

Its made in Iowa, so it could be anything. I notice the name is "use em up", I wonder if it is designed to salvage scrap MT3 tapers by grinding a flat on them? It could be worth asking on The home shop machinist forum.

Edited By old mart on 04/01/2020 21:25:16

Plus 1 for this. I think the idea was that it would allow the use of a drill with a broken off tang.

Titanium is also fashionable for wedding rings (but often presents difficulty in machining).

Thread: Myford super 7B Chuck threads
02/01/2020 14:51:23

Early in my S7 ownership I solved the tight chuck problem by very carefully "screwcutting" the spindle nose thread with a tool that closely matched the correct form.

On the rare occasions that the lathe is used with the spindle nose not in use I protect it with a plastic cover.
