Miscellaneous information and materials wanted

Hi There

A few questions for you.

 

Can anyone tell me when the Chuck cartoons started in Model Engineer, the year would do?

***************

 

Could someone scan and email me the Clarkson Autolock Handbook, at least the speeds and feeds charts but preferably all of it?

***************

 

Has anyone got a pair of rear wheel rims for a Minnie traction engine they could sell me cheap.

They don’t have to be perfect, undersize or part machined considered. Ideally one of them not machined on the inside. I need them for a turning article.

Hi There

The main photo top left of the home page of this site is showing a broken link on my laptop but is fine on my main PC.

Does anyone else have a missing photo and if so, what browser are you using.

Hi There

The Zeus Data book has a page showing how to work out the dimensions for pitching out holes on PCDs.

Does anyone know of this chart or similar in another book?

I would like to use this table/method in an article but obviously can’t just copy the Zeus book.
The data must be constant but I need to confirm that.

Hi There

Many years ago, I had a table of speeds for a machine tool.

What it showed was the relationship from one speed to the next as the speeds stepped up.

It ended up as a saw tooth graph across the chart where you could plot the cutting speed and see how linear the speed steps were.

Does a machine designer or anyone else have an example of this type of chart?

It would save me figuring it out from memory.

Hi there

Has anyone used the type of edge finder that has a point, I am not talking about the sticky pin version, I am talking the parallel one with a point on it.
I assume it is for finding the centre of holes but am not sure how it works.

I suppose you could drop it into the hole and wobble of the edges of the hole in the X axis to find the centre and then wobble of the front and back in the Y axis to give the true centre?

Hi David

 

I had the same problem with my Mill

 

A shizuoka VHRG It has had its thirtieth birthday and still going strong!

 

The link below to an excel spreadsheet, creates a chart with the steps you mention; you can customise it to fit your various machines and get the exact numbers for each machine you work with. Make a separate copy for each machine.

If you have any trouble I would be pleased to help.

Hi David,

 

Here is a link to a free PCD calculator which I find very useful and use all the time at work. It also gives you data for chain drilling holes which would be useful for the portable engine.

Hope this helps.

Hi David,

 

Here’s a quote from the above web page mentioned by Steve which may be useful:

 

“In MEW (Model Engineers Workshop) issue 100 Harold Hall described the formulas for calculating Pitch Circle Diameters…………..”

 

Hope this helps

Hi David, in an index I have there was a posting in Smoke Rings Vol122 3052 1960 page 2. Vulcan. Meet Chuck (The Muddle Engineer). Then in issue 3053 on page 34; Humorous, Chuck, The Muddle Engineer. Aspin. Exhibitions Models compared to his own.

 

Don’t know if this is what you are looking for. I don’t have any 1960’s issues so cannot view them myself, but maybe someone else can.

 

Regards Nick.

[David Clark 13Participant @davidclark13]

Hi Nick

That is fine.

I thought I remembered them from that far back.

There are about 335 entries from B. Terry Aspin as Chuck the Muddle Engineer, from 1960, vol 122, trying to start the motor mower, to2006, vol197, foundry work. A total of 46 years. Ian S C

Hi David

Have you had a response to your question 7 of this thread yet? I was given a set of edge finders amongst which is one of the pointed type of which you speak and I haven’t a clue how it is used either.

Most of this stuff disappears.

 

Anyone remember Reg Prescott?

One of the most skilful British engineers in history.

You may have a seisure when you view his stuff, nowadays it’s actually against the law to have a really good laff.

Hi Jim

No, but one arrived yesterday.

I will have a play in the week.

I have an idea that I can use it in a different way for the lathe which is why I bought it.

Hi David,

In the excellent(?) series of videos from MIT, the demonstrator shows the use of such a tool. According to him you put the pointy bit in a hole and align said hole by judicious use of a finger nail over the misaligned sides.

Hi Chris

Do you have a link?

About 26 mins into video 1

Oh, that simple! The video didn’t play but I have had a deal of difficulty with MIT vids in the past and no matter because the description given here by Chris Stevens and in the narrative on the MIT site shed all the light necessary.

Must remember the KISS principle in future.

 

Jim

[chris stephensParticipant @chrisstephens63393]

What he said! Saved me trying to find it by looking at several hours worth of videos.

Hi Jim,

Once you have been let in on the secret most things are simple, with the possible exception of affairs of the heart and an appreciation of modern art.

Seems to work on all three browsers here just fine – that’s Firefox, Internet Exploder, and Google Chrome. What browser do you have that it doesn’t work on?
