In the centre of Ballarat on the way to the train station,  I meandered around the Rockabilly festival,

these guys know how to have a good time.

Me!

The Ballarat Wendouree ride is an annual event which raises money for cancer research, and the total raised is edging towards $1,000,000 over about 7 years.  Despite posting on several Bulletin Boards I only managed to get 3 (out of a possible 12) on the recumbent team but Douglas Tuck, Damian Harkin and I managed to put up a good show.  Teams ride around the lake for 2 hours and the total laps are counted.  There are other rides that take place on the day, and to be honest, the relay ride is a bit of a kiddy pool with faster fitter riders mostly taking on the rides from 50 to 100km. 

Douglas Tuck finished first in the first lap and no one passed him at all on the whole ride.  He averaged about 30kph.  I was third in the first lap and only a few people passed me in the whole race, amongst them were some of the "Superheroes" team who were actually fit cyclists  on good bikes underneath all the costumes.  Damian got a puncture halfway through the ride but was pretty quick up till then.

After the race I trundled into town before taking the train back to Melbourne.  There was a Rockabilly Festival on in town and dancing amidst the hotted up cars and music in Liddiard St.  So quite a lot going on in Ballarat on this particular weekend.

Oh yes, and my bike is still adorned with the pink number 22 on the back.  So if you get run over by a wooden recumbent bike with pink reflectors on the front and a pink number 22 on the back, it wasn't me!

Hi

A few days ago, I took some time off work and decided to use some of it for for a bicycle road trip.  There is a place I can stay in Airey's Inlet, and I was booked in to a Motel in Ballarat for the Lake Wendouree relay ride , so why not make a tour of it?

Friday Feb 14:
Up early and made the 7k ride into Southern Cross Station for the train trip to Geelong.  My bike is big, awkward, and heavy to move around, but I had some help getting it onto the train so no problems really.  Arrived at South Geelong about 8am and I rode to my friend's Rob's place in Torquay.  Rob wasn't that surprised to see the bike, (having seen a range of my machines) but another mate Paul was very surprised, a wooden fwd bike being entirely new to him.

Rob had bought a tip shop bike for his son Finn for $5.00.  It is a cabable touring machine with canti brakes but now it is garishly painted and has surfboard racks fitted. After a mango smoothie, I went on from Torquay to Aireys Inlet where I stayed the night.

Saturday Feb 15
Made a 7:20 start for Ballarat.  There is no main highway between Aireys Inlet and Ballarat and the first bit of the ride needs to be over or around the Otway hills.  I chose to go up the dirt road to Bambra - and my bike does not cope well with uphills on gravel at all well, so there was lots of pushing to be done.  The basic strategy to employ is shut up and get on with it. Here is a short video I took

So 2 hours for the first 20k to Bambra, and then on over fairly familiar territory to the Colac - Ballarat road.  (So no more navigation then)  This road runs north through Beeac, Cressey and Rokewood .  I hadn't seen these towns before and they were very pretty.  Beeac has a windmill museum celibrating the diversity and craft of Beeac local windmill builders.  Had a nice lunch of dim sims, tea, and coke (I was cycling so this sort of makes sense) in Rokewood before moving on through the hills to Ballarat.  Found the motel fine and zonked it pretty early.

Hi

After a cold start to Summer, its been quite hot in Melbourne for a month.  For the Buckleys Ride I did on January 4, it was mild and wet, but a week later, when I was back at work, Melbourne baked with four fairly relentless 40 degree plus days.  Since then the weather's been up and down a bit, but basically hot and no rain.  And then last weekend, there was a sting, a very hot Saturday followed by a hot and very windy Sunday.

When things get dry, there is a buildup in potential energy in the form of all the dry leaves and grass and trees and branches that surround all the houses and farms in the bush.  Its sort of tottery like a tower of miscellaneous objects left on a table.  Shake it, rattle it , disturb it a bit and it will fall or burn.  So it was during last weekend, almost 5 years to the day after the devastating Black Saturday bush fires which hit our state.

Although not as bad as Black Saturday, the start of bushfires last week puts us in a different situation.  Like the inestimable PJ Harvey sings, "I wanna pistol in my hand, I wanna run to a different land".  There is smoke in the air, there are reports on the radio about fires in Warrandyte and Kilmore and Hazelwood.  People with asthma and breathing difficulties suffer a lot.   It puts us all on edge and though it sounds a bit boring, most of us just want it to stop! 

Anyway, one of the very small bits of silver lining on this cloud of smoke and bushfires is improved photographic opportunities.  Amateur snappers shouldn't really try to get near the fires, but the smoke makes the sun and moon both look bigger and red-tinged.  My humble contribution to the smoke-enhanced-photography-genre is shown above.

In the middle of this my friend Aki came over to get the bike I sold him shortened.  He had had the bike sitting in the garage as he couldn't ride it or reach the pedals with his feet.  The first time he came over was last Sunday and I managed, in a painful comedy of errors, to stuff up the bottom bracket cartridge bearing and the job wasn't finished on Sunday.

But by Wednesday, everything was fixed and I'd replaced the pedals with the clip on type which are almost essential for recumbents.  Aki was waiting at the front door when I got home from work.  We had a beer and very pleasant chat before I took him to the park to learn to ride the bike. Success as can be seen in the photos!  Incidentally, the photos are in the same spot where this video (at about 1:15 minutes in) was taken last September.  You can see how the grass has dried out!

A few days later I got an email from Aki.  He was enjoying riding the bike now and forwarded on a few photos he took, please see below, thanks Aki!

Some Aims for 2014

Could not help taking this photo - my bike at work with the corflute and cable tie tailbox sitting happily next to its counterpart, the corflute and cable tie sign on some pallet racking.

Hi

Well judging from one of my last posts, which mentioned managing to do a couple of 2013 bucket list items, stating some aims for the year and then attempting to achieve them seems like quite a reasonable idea. It sets up the blog for the rest of the year and (sort of) explains some of the ludicrous bikes and things I am attempting to make and do.

"He robbed a bank"
"Yeah, but it was on his bucket list"
"Ok then, Cool!

So here we go, nothing too ambitious here.  This is the official list related to bikes etc..
* Make a Velocino . I have a separating bike that is hanging out to be converted,
* Complete 1000 Audax km in the Audax calendar year, over several rides.
* Engage with a university in some way on a bike related project.
* Ride to and from work 3 times during a working week.  

A slightly more ambitious goal is to complete an Audax 1200k ride.  This needs top level bike equipment (lighting, bike etc) and nutrition even to make it.  Unnofficial goal.  The hot weather we are having makes it hard to train.

Thats It!

Some Philosophy of Bike Building

Suspension Block and Packer for Aluminium Bike

From right to left we have * Existing suspension block from old pedal rubbers, cable ties and a plastic bike tyre lever, * Raw material for new block is an engineered Mackay multicushion industrial damper * which was cut up and combined with a small piece of "Unimold" and some cable ties to make the new block.

The block in place.  Not tested yet!  The extra width of the cable ties keep the block in place.

This blog post is just a bit about replacing a suspension block in my aluminium recumbent with something (hopefully) a bit better.  But really it illustrates some of my bike building philosophy as well.  If you are trying to build something new, you don't have to solve all the issues concerning it at the start.  Once you build it, you will probably find an answer to the issues, and if that fails, and you scratch your head a bit, you will eventually find a better answer.

So at the start of the project to build my aluminium recumbent, I winged it to make the suspension block, and this blog is old enough and nerdy enough to have this process documented.  Since then I have used bits of bike pedals put together to make suspension blocks for the aluminium bike.  This works fine except when it gets hot, say 30 plus degrees like it has been lately here.  A lot.

Then the rubber gets mushy.  For goodness sake, what would you expect?  It was designed as a Chekoslovakian bike pedal, and when being used as an Australian bike suspension system, it just says "Bugger Off" and starts to crumble.  Then it has to be replaced or rearranged so the pressure's on a less crumbled bit.  Which is not really good!

So the new solution was a happy coincidence,
* my (slightly worse performing but still cool) wooden recumbent is heaps good enough for riding around town, so I can use that, and rest and repair my aluminium bike. 

* the build of the wooden bike involved a (fully designed in, woo-hoo) Mackay suspension block, and I bought a few of same dimensions but different spring rates (ie kg/mm deflection) to try on the new bike.  It turned out the softest of these was good on the wooden bike.  The Mackay block handles hot weather fine.

So with 2 harder blocks left, I finally had some material for a long lasting suspension block for the aluminium bike, and a week or so ago when I had some time I set about making it to the template of the pedal suspension block.  This involved hacking off about 2cm of width to make it fit in the pocket in the frame, and bolstering it by 15mm or so with plastic to make it the right height.  You can see the results.  Now I hope the damn thing works!  Will report later.

Robert Cook and the mob.

Hi

This week I didn't make any mistakes about the start of the bike ride, which went from Ivanhoe out to Eltham and then back along the Darebin Creek Bike Path.  I joined up with Robert Cook and his homemade machine on the way to the start of the ride, which included electric bikes, recumbent bikes, recumbent trikes , upright bikes and Graham Signiorini's chopper bike.  Near the end of the ride we were overtaken by some kids who had motorised  / engined a pushbike and were testing it without a rear tyre, just cruising along on the rim.  Needless to say within a k or so of them passing us, we passed them, busily scratching their heads, the tyreless wheel was no more, just a mess of mangled spoke and rim.  All for now.  Nice to see everyone on the ride.

A Sunday Ride

Cheap!  An oversize front wheelset for a Billy Cart at the Reservoir Tip Shop.

Not So Cheap!  $100 for a swingbike at the Reservoir Tip Shop

Darryl checks out my bike at Savers in Sydney Road.

All this stuff fits in the back of the bike.

Hi

Last Sunday I intended to join a few others from the VicHpv group on a ride but stuffed things up by not reading the email properly and thinking  the start of the ride was at Malvern (near) and not the actual start point,  Carrum (far).  On getting up on Sunday, looking at and finally confirming the ride start point, I was too late to get to the start point by bike in time.  So I opted for a fairly familiar shopping trip and bike ride through Fairfied, Preston, Thornbury, Reservoir, Carlton, Fitzroy and finally home to Clifton Hill.  Sometimes I see George or Chris or Chook on this ride and often pick up books, videos and shopping along the way. 

So this time I bought some water bottles, books and videos at the tip shop and continued on to Savers in Brunswick,   one of the few op shops I know of that are open on Sunday.  Darryl was there , I reintroduced myself and started a chat with him, he had been at some of the Vichpv rides a few years ago.  Then it was home via Aldi and the Capital City Bike Trail.  The photo at the bottom shows the junk I collected along the way.

I am writing this on a Friday.  There is another Vichpv ride scheduled for Sunday.  I will try not to stuff up getting to the start this time.  But if I do, the Tip Shop / Savers bike ride is always an option for the way home.

A Bit of a Summary of 2013

Wooden Bike, Early 2014

Wooden Trike near Lara, Buckley's ride 2013

Wooden bike components, from Bottom, plywood plate, hollow timber 90 x 35 pine and their assembly to make a chainstay.

 A few weeks ago, after seeing my blog entry about my trike, Trevor Gosbell and Chris Rogers from Audax asked me about writing an article for the Audax newsletter, "Checkpoint".  So I had a go, and present to you my draft version.  It makes a reasonable summary of the bike development work I did last year and makes some sort of sense of all the various blog posts.  Here we go.


"Since 1986, I have been building recumbent bikes but for a long time the activity was a sporadic, hit and miss affair.  It took challenges in the form of the Bike Vic "Round the Bay in a Day" and OzHpv races to step up my bike quality and make machines capable of longer (200k) rides.  Now, many years later, I've been active in OzHpv and done "Round the Bay in a Day" about 15 times, and the last 2 times were on wooden homebuilt recumbents.  This is the story of the wooden bike circumnavigations.

The bikes I've made for the last few years have been front wheel drive recumbents with a big wheel at the front and a small one at the back, and a large tailbox (storage box / helps make you visible / aerodynamic aid) behind the seat.  The front wheel drive setup has the bottom bracket fixed to the frame and the front wheel steers as usual.  It works!  There has been steady progress over several versions with a few sideways steps along the way. Usually I'm not ashamed to have a go at something a bit unusual, or that might not even work and its often more fun cobbling something together in the shed than planning meticulously for a highly polished result - I get to do that enough in my work as an engineer!  At the other end of the scale I don't mind spending money on good bike components either.

I've been through round tube steel frame with cast lugs, lasercut round tube steel frame, separable steel frame, rectangular aluminium frame and trike versions of my big at the front bike before arriving at the most recent timber frame bike I now have.

The aluminium frame recumbent bike which I still count as my daily ride has been very reliable for commuting, beer fetching, Audax riding and light touring since mid 2012.  It has an NC routed timber seat assembly which slides up and down the main boom of the bike to adjust for leg length.  After a while an "itch I wanted to scratch" was to make a version of this bike with a wooden frame and so in late 2012 I ordered some NC routed timber for the seat and also put "doing a 200k ride on a wooden bike" on my 2013 to do-list.

By May last year I had a wooden bike on the road and targeted in Phil Gidding's winter surf ride for the "wooden bike 200".  When the time for the ride arrived, the weather didn't look good, I was undertrained and parts of my wooden bike were falling apart, so the trip was done on my aluminium bike instead.  Just as well, the Winter Surf Ride weather was shocking with a huge storm front coming through late afternoon, making riding impossible for a while.

In mid last year another itch I had to scratch worked its way into my mind and that is a recumbent trike of the "iLean" family.  This is a clever method of making a leaning trike invented by Mr Vi Vuong from California in the US.  Who said everything the is to do with cycles has already been designed?  Most of the bits I needed were already on my falling apart wooden bike, a friend did the necessary timber routing in exchange for a bottle of wine and I unscrupulously swapped pedal axles for wheel axles on a pair of 20" wheels.  Voila, a new trike was born, and it worked quite well.

Time was running out for me to finish a wooden bike 200 in the calendar year and there didn't seem to be a flat 200 coming up so I chose a date and opted for a Buckley's (Round the Bay in a Day Equivalent) permanent to try my trike.  The day I chose was unfortunately raining and I had a headwind for 70k straight at the start.  It was a long day in the saddle but I got there in the end - a 5am start and 8pm finish. I was very glad to get home and tick one item off the bucket list.

In the middle of building the trike, I designed a refined, weight reduced version of the my timber bike, then ordered some more NC routed timber and lasercut steel lugs and handlebar bits to make it.  These bits sat in my shed for a few weeks till late in 2013 I got a chance to put all the parts together.

Chris Rogers had asked if I wanted to go in the Buckleys ride proper on January 4 2014 and I agreed.  Coincidentally, my new wooden bike was coming together  very well and I'd had a good 30k or so test ride on it on January 2.  So it was the wooden bike for the Buckley's ride.

This time the ride went very well and I was in at 5:30 pm after a 6am start.  Ian Knox and Kevin Linnett were on recumbents and I knew Rick Harker and a few others from previous rides.  Thanks to Chris Rogers for organising the Buckleys rides and Ian Knox who leant me his mobile phone and support.

Best wishes, Regards

Stephen Nurse
