The Cleveland Connection

 

For the last year or so I have been clearing out my mum and dad's house in Kew, as my mother died last year after a short stay in care, while Dad is in aged care due to physical weakness. My brother-in-law John and his wife Lynn helped me significantly with removing items from the house and taking them to Op Shops (Thank-You!). This included a large number of books.

Long after I thought all the books were gone, and amid a family kerfuffle about who was to attend a Christmas gathering (if you want to start organising something do it by email and not by word of mouth!) Lynn rang me to say she had rescued a few photos and personal items from Mum and Dad's stuff. I was volunteering at the Wecycle bike shed at the time and Lynn offered to drop everything off at my place, which she subsequently did. I stashed most of the photos in with the large box of other photos that came from Mum and Dad's place, but a ring bound booklet attracted my attention.

It took a while to work out what it was - really it seemed like a series of curriculum vitae and recollections from a group of Melbourne doctors called The Cleveland Fellows. It is full of source material from doctors without much connecting narration, but after taking it to Dad to read (he had forgotten its existence), then discussing it with him and reading it again myself, I can fill in the gaps a bit.

The story goes back to the Second World War where a US Army medical unit called the fourth general hospital established itself in Melbourne. A wikiPedia page devoted to this unit is at https://en.wikipedia.org/wiki/4th_General_Hospital_(United_States_Army)  , and this page along with its references were part of my research. The unit arrived in Melbourne at the end of February 1942 and on 12th of May 1942 the unit moved into the Royal Melbourne Hospital building. The booklet I have was compiled by the physician Tom Hurley for a 60th anniversary dinner to commemorate the unit’s occupation of the Royal Melbourne Hospital.

Subsequent to the fourth general Hospital unit returning to Cleveland, Melbourne doctors applied for and were sponsored to leave and work in Cleveland for a year. These exchanges took place between 1949 and 1991. Doctors were of my dad's generation (Born 1931) or slightly older through to the most recent visitors who were not much older than me (born 1960) .

 The organizer of the dinner was the physician Tom Hurley (Dad recalls endocrinologist Ian “Skip” Martin was also an organiser) and the dinner was held on 9th of May 2002. Tom had requested curriculum Vitae and recollections of Cleveland from all who attended and compiled the replies in a booklet, presumably distributed to attendees. Contributions range from curriculum vitae only to single page letters with a paragraph or two of Cleveland recollections to 2 or 3 pages of Cleveland recollections. Most interesting were accounts about cultural life in Cleveland including playing and hearing music, and in Melbourne, where one doctor laments AFL club Essendon’s lack of form!

On the Melbourne side of the exchange Pincus Taft is mentioned often and I recall Dad was an associate of one of his relatives,  the dermatologist Eric Taft. On the Cleveland side Max Miller who was concerned with diabetes is mentioned often, but I couldn't find him in the list of officers in the unit's history which is here https://web.archive.org/web/20120718035458/http://www.med-dept.com/unit_histories/4_gen_hosp.php  

It has been interesting and fun to read this book and to unravel the small mystery about it. It's been a good way to connect with my Dad. My son is a  medical researcher with overseas contacts and I plan to pass the “Tale of two hospitals” on to him soon. He had previously snapped up several medical histories and medical biography from Mum and Dads collection.

Icosahedron Sculpture

 

Hi

For a few months, I have been working on a bike rim icosahedron  (20 sided figures which nominally use triangles as sides), with the starting point gathering enough 27" bike rims to do the job. Before Christmas, I started putting one together in my girlfriend Mary's back yard, my own backyard having too much cr&p (junk in the form of other bike sculptures mostly) in it! 

As well Mary was having a Christmas lunch, this could be the star attraction - along with Mary's excellent cooking of course!

To join the bike rims, making edges was the first step, and I did this by drilling wooden joiners at the dihedral angle using a 3d printed jig. These were put away for a few weeks till I had time to build anything. Finally, close to Christmas, all the wheels and tools and edges were bundled in the car.

Assembly was only partly successful and partly done before Christmas, the bike wheels weigh enough to rip apart the joiners. But Christmas lunch was a complete success with Mary, me and 5 guests laughing and eating and reading the daggy Christmas Cracker jokes almost continuously for several hours. 

Graham had arrived completely soaked by the rain on recumbent bike and was given a new set courtesy of Mary. Later he rode home in the rain again and even later still returned the clothes, dry washed and ironed to Mary!

I will work on another joiner for the icosahedron, this time from steel tube and wing nuts, and may remove the spkes and hubs from the donor wheels.

PS 3 wheels make quite a neat unit, but when the units are joined up using spoke holes, they act like dodecagons. I've made a pic of this using 20c pieces.Will report further progress.

Bike Rims Article

 

Cycling is about staying fit and using resources wisely. Recumbent bike makers can even reuse old bike parts to make new machines – its been very satisfying for me since about 1987!  Recently I’ve branched out to use old bike wheels in non-recumbent things.

 I have a 3D printer and a few years ago developed some designs to join CDs together  to make geometric shapes (see article here). CDs are round just like bike wheels, and so I've gone on to use CD joining techniques to make bike wheel versions of the mathematical shapes called platonic solids. These include tetrahedrons and dodecahedrons and I am working on a 20 sided icosahedron.

 

                 

 

Inspiration for the shapes comes from the bike dome at Ceres in suburban Brunswick– I don’t anticipate building anything that big and my designs might be a bit more orderly, but the dome shows what can be done. The Trisled newsletter recently featured a similar community-built dome at Meeniyan in Eastern Victoria.

 

A few weeks ago, I gave my small tetrahedron table away to my friend Simon for his 60th birthday and was able to transport it to his place by bike. That was on the way to the Wecycle bike shed where we volunteer. At his party later that evening, it was set up in his garden, staked to the ground as its base is not very big and its prone to tipping.

 

 

 

A larger tetrahedron I made uses a raft of 3 bike wheels bolted together to form a side of the 4 sided tetrahedron. I’ve had this for quite a while and have transported it by trike and trailer. I’m not sure if it qualifies as a road train or pantechnicon, but this is a 14 wheeled vehicle!

That’s a fun story – made me chuckle. Here’s a pic from the day.

Thanks for letting me use the sculpture!

Cheers

Heidi

Once I took it to a community bike day and it was noticed by Heidi Marfurt who is the Darebin Council’s sustainable transport officer. Just a few weeks ago Heidi wanted to use the sculpture at another community bike day, The Rezza Bike Day.

 

The sculpture uses the wheel centres as axles for small windmills which also use cds as blades and a 3d printed hub. That is just a fun thing but shows what can be done with recycling. When Heidi asked me to loan the bike sculpture I decided to extend it and worked out I could make something quite high (about 1.8m) without using only 6 extra bike wheels.  The pattern is shown in the picture – as long as there is part of a wheel on an edge, then the outer triangle shape can be made, even if the outer triangle is not completely filled in. I needed 2 goes of putting it together to get the pattern right.

 

                 

 

 

Actually loading the sculpture sides into the Heidi’s car involved Tetris-like manipulative skills and in the end only the smaller tetrahedron would fit in. A few days later Heidi came back to my house with the sculptures and they were festooned with ribbons and a couple of the CDs had broken off. I was thinking it's a bit like those stories where a garden gnome gets kidnapped and sends postcards from Queensland and then turns up months later with a suntan and tattoos! Heidi was quite sick of loading and unloading the sculpture in cars by this time, but the whole event went well and the sculpture was appreciated.

 

Most recently, I used the frame for painting a crank arm on a Wecycle repair bike. This was to turn a silver right hand crank black, as the original black one had a stripped thread. The other hanger in the back yard is the dodecahedron, used as my regular clothes line.

 

Sofar I’ve been making wheel joiners (they act as platonic solid edges) from steel tube, pvc pipe or wooden dowel. When there’s a narrow angle (ie on tetrahedrons), the large steel tube seems better, and the drilling can be marked out with dividers and a centre punch. For larger angles like on a dodecahedron, I use the dowel, and drill with the help of a 3d printed jig. This wikepedia page  

https://en.wikipedia.org/wiki/Table_of_polyhedron_dihedral_angles  gives the relevant angle between faces, it is called dihedral angle in geometry-speak.

 

 

 

I plan to go on building the bike wheel sculptures, and mostly use 27 inch steel bike wheels. The 27 inch bikes are now of an age with the are often being thrown out and are not worth restoring - or are only worth restoring if the wheels are swapped out - so they end up in the recycling dumpster at Ceres. I can load up about 4 wheels at a time on the back of my bike, even more if the spokes have been removed. Also I know Serge, the volunteer who does most of the stripping of unwanted bikes at Ceres. We stop and have a chat while I’m there, and swap notes about the Wecycle and Ceres Sheds and our bikes.
