Publication News

Andrew Dressel on the Panthertrike tilting trike.

 Hi

When I was studying at Uni for a Master's degree a few years ago it was part of my job to publish articles and visit conferences. This was a big catch up as I had worked all of  my professional life in private industries and visiting and especially presenting at external conferences wasn't part of the culture. So uni mkII an few years ago (mkI engineering degree was in the 1980's) sort of turned me on to scientific publishing. 

I've been researching for a new edition of my book and so clicking all over the internet for stuff and eventually found this article from the University of Milwaukee Wisconsin which was presented at this conference and saw some of  my work quoted at least in picture form. So I found a mistake in the article and wrote to Andrew Dressler about it and he wrote back and we had an amicable conversation. Here's a bit of our emails.

From Stephen Nurse

"Hi

I'm in the process of reading your article here. First of all, nice work, there's a lot of detail there and I hope the project is a success for you. 

I found a few mistakes related to my work. Its not really a big deal but if corrections could be put into the paper it would be appreciated and it would probably help the paper overall. Fig 2 shows leaning trikes which are both my NLT's, neither of them are Vi Vuongs and this should be fixed one way or the other. For examples of Vi's work see here , you might have to do frame grabs to get whole pictures of trikes.

None of my work is cited in the article but I think this article (talks about crank length and has a pic of Vi) would cover it.

If you're interested, the whole of my trike design is on thingiverse, here is the link

If you have any questions please ask!

Mr. Nurse,

It is great to hear from you and thank you for kind words and fine contributions to the field. Thank you for the link to the Thingiverse!

I apologize for the mistakes and will do the best I can to get them corrected.

I also apologize for somehow not citing your work. It was purely a knuckle-headed mistake on my part and in no way is meant to be disrespectful.

I am relieved to see that I managed at least to cite your work in our recent ASME paper, which I have attached. Sadly, it does repeat the Fig 2 error.

Meanwhile, Mr. Pierson and Ms. Shortreed have graduated and moved onto exciting and lucrative careers. Happily, Mr. Van Asten is still with us and hoping to make some progress in the coming year, despite how badly and embarrassingly we have bungled our handling of the pandemic. Wish us luck.

So all very polite talking to Andrew and good to see some of my work having an impact. The Panther Trike website is here. Good luck with your research !

Proposed Kretschmer bike and the min and max developments his proposed gearbox brings. (Snip from my article for this velomobile seminar based on the Kretschmer article here . )

 And I've written for a Velomobile seminar, and also to Jeremy Garnet from Velotegra.  But only 3 articles were received for the seminar sofar, so its in limbo a bit. 

Michaux Bicycle, Bantam Geared Hub Bicycle from the 1800s and their effective wheel sizes in blue. 

 Anyway, I'm quite pleased with how the diagrams came out.  I'm quite a visual / experiential / doing person and these circles made a bit of sense to me, more than a spreadsheet table would.  Look forward to revising and eventually publishing the new article.

Regards  Steve Nurse
