Thread: Benedict Cumberbatch featured on Cover of MEW 243
09/06/2016 19:47:01

So who's the old guy on the cover of MEW 243 ?wink 2

Well I believe his name is John Stevenson.

Nothing like Benedict Cumberbatch but does have a passing resemblance to Jim Broadbent (Roy Slater in Only fools and horses)

Thread: Drummond M Type Lathe
05/06/2016 20:59:58

No Worries Eug,

We all make mistakes and you are NOT a twit, just remember you have forged your place in the history of dummond lathes with the inspired use of a secondary thrust bearing on the M type spindle.

I have followed your lead on my '29 drummond and '48 myford, just the job Eug makes a real difference.

All the best Geoff w

Hi Pete,

Just spotted this post.

Thank you so much for your hospitality last month.

Ann and I enjoyed the company of you and your wife very much.

I have to say that the M type was by no means the best machine in your workshop.

That distinction goes to your Harley Davidson, a real dream machine!!!!

Best regards to you and you good wife.

It sold very, very quickly.

thanks geoff

Hi All,

I've had a part built stuart 10v for about a year now.

I bought it from this forums for sale ads.

I thought I'll have a good look at this and then complete it.

All I have done is look at it!!!!! ......I'm not going to finish it.

It's currently listed in the for sale ads, includes all parts and the work done is to a high standard

Also included, drawings, the Andrew Smith book and a stuart catalogue. It needs a good home!!!!

Thread: Drummond M type selling
08/01/2016 18:44:23

Hi Sam

It's what they call a "knee planer" (the large gear will plane your knees if your not careful)

Very rare and looks like a good example.

£250 I would say is cheap, try it £350 -375 buy it now, should sell at that price.

If I had the room I'd buy it, already got two m's though.

Thread: DIY Milling/Drilling Spindle
03/01/2016 10:18:19

Hi phil

that looks like a neat set up you have on an original potts column type milling attachment.

G P Potts first introduced the column attachment in a two page article in vol 76 of M.E. magazine back in 1937.

It was originally made for use on the very early Drummond M type lathe having a two piece central locking bolt the top half of which had a threaded collar to screw down on to the top slide tool post stud.

I am currently making a column type potts so more pics of your attachment and drive would be of real interest to me.

No rush Phil when you have time, best regards geoff

I have a 1/4 hp 1400 rpm parvalux which I use to power a potts milling attachment see photo.

It provides adequate power for end mills up 6mm used on familiar model engineering materials. The key for me is fine feeds, high speed and light depth of cut.

I have the potts mounted on the vertical slide and the power from the parvalux is via an overhead drive.

The potts is really robust design. I was lucky to acquire an old set of castings about two years ago. They were supplied to the original buyer by woking precision models in 1974 so it was best part of 40 years before I got them and made the attachment. As far as I know the castings are no longer available but if you are ever offered a set, buy them. Apart from usefulness of the attachment it's quite a challenge to make one.

Santa brought me a nice pair of proper steel-toed safety boots this year. Came after I picked up the Drummond top slide and turned it over to make sure there was no swarf on the base before re-installing it. But the toolpost was not secured and fell straight on to my soft leather desert boot. Youch!! Hi Pete, Is the top slide ok?

Hny Pete, see you in March, Hope your drums ok when I get there! sounds like lathe abuse to me, try to keep it one piece!!!!

Will be in touch via email soon

Thread: A & R Precision 'Dickson' Toolpost -- Screws Used
03/10/2015 11:27:32

I must be one of the few people who were unhappy with A & R.

I bought a tool post and 4 holders from them last year. With the holder in place the locking position on the cam was a long way off being right. It was only after fettling the shoulders on the clamping bush (if that's what it's called) that I got the clamping position feeling right i.e. you could feel the cam pinching securely.

They now work fine but it took a couple of hours to get there.

With the above in mind I think there are always likely to be problems with any mix and match from different makers.

As a footnote I must be one of the few people who have not taken the Dickson tool post, I don't really like the system and as such I rarely use it, Much prefer the quick setting norman tool posts on my M type.

Hi Neil,

You have a solution in your email box.

What are the chances of it appearing in MEW?

Sorry Neil couldn't resist that!!!

Hi Ady,

I remember you, you used to post a lot of messages on the Drummond yahoo site.

They were always of real interest, where have you been?

You're dead right about the M, the spindle bore is way to small, a real pain in the ****.

I would also add that the rack feed is barmy, winding the hand wheel clockwise and the saddle moving towards the tailstock. How anybody thought that was a good idea is beyond me.

Do fit that second thrust bearing as recommended by Eugene, trust me it really is worth doing.

Get yourself back on that drum site asap.

Thread: lathe books.
21/04/2015 18:44:01

Hi Gareth,

I think we all have our favourite book, often I feel influenced by the type of lathe we own.

I have two M types, a Drummond and a Myford.

The amateurs workshop by Ian Bradley has many references to my machines and is therefore the book I have found most useful.

Having said that even if you have another type of lathe this is an excellent book and for me a serious challenger to Spareys Amateurs lathe.

Hi Steve,

I noticed in your photos that you are still using an M type.

Is it the same one that featured in your M.E. articles in 1994?

I remember the articles, some really innovative repairs and modifications

Thread: A & R Precision 'Dickson' Toolpost -- Screws Used
02/04/2015 11:18:01

Hi Gavin,

You're right the tool holder is not gripped securely.

For it to grip securely the cam needs to be nearer to tdc

If you remove the shouldered locking bush and carefully file the inside face of the shoulder it will solve the problem. You will need to take equal amounts off both sides so check with a micrometer as you go along.

I found removing about 10 thou did the job.

This brings the 2 webs on the locking pin into a position either side of the flange on the adjusting screw and the cam to about 10-15 degrees off tdc.

You will find that the "feel" is now right with the cam "pinching" and feeling really secure.

Just make sure you don't remove too much material, check as you go along

Hope this helps best regards geoff

Hi gents

Thank you for your replies.

I did ring A&R, there view was that clamping pressure is uniform at all points on the eccentric. I’m not so sure, it currently locks a good 45 deg. from TDC, which as I’ve said just doesn’t feel right.

A small amount skimmed off the inside face of the shoulder on the spring loaded clamping bush will draw the bush in a little more and the eccentric will get closer to TDC.

I am still mulling it over a may give that a try. I do take your point about getting to close to TDC, that would be detrimental.

Some years ago I made GH Thomas spring loaded retracting tool holder and found that the eccentric locked the tool securely (and felt right) about 10 deg from TDC.

Thanks again geoff

I recently bought a Dickson tool post with 4 holders from A&R precision.

All seems well until I clamp the tool holder in the tool post.

The "problem" is that it clamps too soon, nowhere near TDC on the eccentric.

The holder locks in place but it just doesn't feel right, not really secure?

Is there an optimum clamping position for an eccentric. Should it be close to TDC?

I can see a solution to the "problem", if indeed it is a problem.

Any thoughts anyone

Thread: NEW Original MYFORD Dickson type tool posts & holders
07/02/2015 16:42:55

Just bought a tool post, four holders, key etc from A and R. precision.

I am like all others commenting in this strand really pleased with the buy

At £90 for the lot it's a real bargain.

I told Darren he could sell 'em for England at that price and quality
