What Did You Do Today (2016)

[Four stroke FredParticipant @fourstrokefred]

Good day Windy, Thanks for the DVD disc of the flash steam to you gave to me at the Pickering model engineers meeting earlier in the year. I am amazed at the performance of your hydroplane and flask steam. I enjoyed the night of the talk and seeing the work the members had brought along. Enjoy your Christmas and I may catch up with you again next year as I am considering a return to the MEX with the tractor and perhaps Yorkshire.

Carl, really enjoyed your article on the rotary table, and am considering doing the same. The number of stepper motors, however, appears to be a minefield. I have been unable to find a motor that exactly meets the specs of the one stated in the article.

Could you advise where you obtained yours, with a full description of the motor if possible?

Many thanks,

Andy

Nema 23 is what you should search on, different numbers refer to more or less powerful motors ( and physically larger or smaller of course). A Nema 23 should be more than enough for a small sized table with a 90 to 1 ratio. Mine is a 75 to 1 and i can't stop the RT turning by hand. There are plenty of other articles regarding converting RT's on the web. Mine uses a pic chip rather than an arduino, has a larger LCD display and a small numeric keypad for menu and control functions and was relatively cheap to build. Mine uses a redundant laptop power supply at about 19v and 3 amps. All the other electronic gubbins resides in a die cast box from Maplin, ebay for the rest of the modules needed apart from the PIC board.

[Carl Wilson 4Participant @carlwilson4]

You are right. NEMA 23 refers to the frame size.

The table in my article uses an Arduino because I feel this is the easiest platform to introduce microcontroller to those with little or no experience of them. The Pic requires more investment of both time and resources to master. The Arduino can be set up and programmed in a matter of minutes.

As for the Lcd, well, it’s as big as it needs to be!

Carl.

Whilst I did enjoy your article its almost a word for word copy of Gary limings article in digital machinist magazine winter 2013

Is this ok to republish the article in MEW?

I know you credited gary in places and he has allowed the use of his software download

Here we go. I wondered how long it would be.

Firstly. I have Gary Liming’s permission to use his software and his blessing. Using software as an integral machine element is commonplace in engineering and has been for over 30 years. That was my point.

Second. I have not seen Gary Liming’s article so I would not know. My article was simply a straightforward description of exactly what I did.

Third. If it wasn’t ok to publish, do you honestly think Neil Wyatt would have done so?

Fourth. Your implication that I plagiarised someone else’s work is beneath contempt. As are you.

I had a need to automate indexing in my workshop. I put together a system to do this. I wrote a description of it. My intention was to try to put some copy in the magazine of the type that I would like to see, as well as giving an intro to those who have little or no experience of the benefits that microcontroller can bring.

In future I won’t bother.

[Ian ParkinParticipant @ianparkin39383]

I'll say no more on the matter but I find its absolutely unbelievable that you had not seen Gary Limings article before writing your article..even some of the diagrams are the same

How you could use his software and description of its use without reading his article is beyond me

[Nicholas FarrParticipant @nicholasfarr14254]

Hi, I got my copy of ME 4549 this morning and having a quick look through it, was puzzled about photo 29 in Brian Baker's Steam Raising Blower article. The caption below the photo says "First half of the operation finished" which didn't follow logic from photo 28 of parting off the 70mm pillars. Turning the page I noticed the same photo as 38, which is in the correct place. I could then imagine what photo 29 looks like.

Regards Nick.

Hi Michael,

The paint is called "One Shot ", its a sign painters paint. You brush it on, "and let it self level". Don't go back over it with the brush once you've applied it to an area. Attempting to brush after the paint has started to skin over will result in a poor finish. Two coats are rarely needed. I have used this brand of paint for all my small tool restorations, and it is quite durable.

Thanks Mike, It looks fab, I'm not going to argue with one coat if that's all it needs, and yes I imagine the "skin" would start to spread if you tampered with it half set. Doesn't the metal need any special treatment or primery, can I just go over regular paint?

If you read that article closely, Ian, you'll see that it says "I have Mr. Liming’s blessing to use his system and to reproduce it here."

It's not plagiarism if you quote your sources and hardly underhand if seek their agreement before doing so.

[Ian ParkinParticipant @ianparkin39383]

I did say that he had credited gary for the project in my post

But have you read the article by gary in digital machinist Neil?

But I still stand by my comment that if Carl hasn't read or seen the article and yet managed to come up with exactly the same diagram of the circuit layout and linked to the software download I cant believe that

Carl I sincerely hope that you 'do bother' in future. I enjoyed the article and the way it was written giving the appropriate credit to your sources. I have now placed your article in my 'must do' folder when those hard to find 'round tuits' become available again.

I've read the Gary Liming's online web page, and yes it covers the same ground but Carl's article is clearly his own words.

The 'exactly the same diagram' you refer to is probably the one where Carl says "Figure 1 shows the wiring for the system,. I have adapted this from Gary's original'.

If you look carefully, Carl has deleted the two temperature sensors – which should not be a surprise as that is how he says he changed the diagram in the text.

Carl freely acknowledges Gary as the original source of the idea – he explained this to me right at the beginning (I still have the email from May 2015) before we published and made it clear that Gary Liming had previously published a write up in the American magazine but was happy for Gary to write up his own build.

No, it is no coincidence that both the article and diagrams are similar, but this has all be done 'out in the open' with the full knowledge and blessing of the author of the original article.

Nothing underhand or unethical has been done here, as I say Carl took care to make sure I was fully aware of the situation from the beginning.

Specifically on your final point, Carl HAS seen Gary's website (as he makes clear in his article), my assumption is that Gary based his magazine article on the web page and that would explain the similarities.

[Carl Wilson 4Participant @carlwilson4]

Thank you for all the kind words Neil and Limpet.

Whilst some may find it trivial and feel able to brush these things off, the allegation that I stole Gary Liming’s article is one of the worst insults I think I have ever received.

I would not do such a thing. The circuit diagram is similar because it is included in the read me file in the download – all of which is in the public domain and the use of which was discussed and blessed by Mr. Liming.

My article is based on the write up I dud on my website http://www.britishreactionresearch.blogspot.co.uk

Gary did me the honour of reading through this and of pronouncing himself well pleased with my rendering of his system. He was more than happy to see it go into print.

[Another JohnSParticipant @anotherjohns]

Hi Carl;

Having read the original, but not the MEW version:

1) having met Gary Liming at the 2015 CNC workshop in Detroit, he seems like a really nice, down to earth guy. I believe that he just wants to get the ideas out there, to the betterment of all.

2) Having written 3D rendering software (open source) I used to google for particular text strings, and it's amazing where my code ended up – with zero attributions. I even actively helped some colleagues with explaining/adapting my code, bugs and all, and one in particular ended up using that adapted code in the founding a 3D company; the company's name you'll see on this forum. They are very nice guys, do a very good job, and I go out of my way to say "hi" when I see them, but, it would have been nice to have some little "thanks" of any kind from them.

Sounds like you gave both attribution, and your own thoughts/additions/deletions, so it sounds ok to me.

Pseudo-related – It is incredibly difficult to come up with original ideas, which actually suits ME and MEW (and almost all other mags). As the readers change, what is "old hat" to one is "wow! Nice idea!" to new readers. It took me a couple of decades to understand and accept that fact, and if we don't keep the education process going, the hobby is dead.

Regards – John A. Stewart.

Following the successful change in my Boxford electics and the addition of a coolant tank, thanks to the very helpful advice received via these pages, I've actually done some turning now and am amazed at the difference in finish between dry and coolant use.

Yesterday I went to an all day seminar at the local gliding club on pilot/owner maintenance. In other words what EASA allows the owner of a glider to do, as opposed to an inspector. As far as EASA is concerned the owner is responsible for organising, and possibly doing, all maintenance, even if they've never held a spanner before! Of course I'm an owner, and pilot, but since I'm also a BGA inspector I can sign off work anyway. However, as an inspector I may be called to sign off work by non-inspectors, or to issue an ARC where the owner has done, and signed off, a lot of the work. So I thought I'd better find out what the owner is allowed to do, and how to judge competence. Turns out to be rather a lot, the main exception being that they're not allowed to fiddle with primary controls or other life critical systems. It was also a chance to meet the BGA CTO; nice guy and very approachable, unlike the last one.

Today was spent largely in the garden hacking back the blackberries. However, this afternoon I got my neighbour to help me lift the arbor press on to the bench. Took about 5 minutes and no trips to A&E needed; a win-win situation. I knocked out a few large washers and bolted the press to the bench with some stainless steel M12 bolts and nylocs from the spares bin. The ram and lever were cleaned, greased and replaced:

Later this evening I started machining the slotted plate that will go on the arbor press. The 3/4" and 1" slots were drilled and then finished with slot drills:

For the 1-1/2" and 2" slots I'll chain drill out the waste and machine a circle with the boring head. Then I'll chain drill the waste for the slot and finish with an endmill.

CTO = Chief Technical Officer

EASA = European Aviation Safety Agency

ARC = Airworthiness Review Certificate – a paperwork exercise to check that the aircraft is 'compliant'

Wish you put that at the start

Turned a replacement plastic plug for the top end of the polarscope hole on my EQ3 mount. A bit tight, so I hollowed it out and now it fits snugly and makes a satisfying 'pop' when you pull it out.

Great fund turning plastic with a boring bar and seeing it flow like pottery on a wheel!

A strangely satisfying little job! Where would I be without a lathe?
