Timber Chainguard

Victoria separating bike with timber chainguard on modded bike....

And on highly modded velocino.......

Still needs a bit of work!
Hi, in the last few days I've been working on a chainguard for my separating bike which is timber , and half hockey stick guard and half trouser guard.  Anyway, I think the idea is ok but this one needs more work, and to be a bit narrower.

It looks a bit better on the modded bike and not on the Velocino version.  You can only take in so much and the Velocino already has enough going on!

Anyway, I will continue on with this shortly.

A trip down the coast

Squeezed the bike into the train.

Near Anglesea on the....

Great Ocean Road
Edible Brassicas thriving.


At the end of last week I had finished a slab of writing for a conference paper and so planned to get away for a few days. Very fortunately my family has a place to stay on the West Coast of Victoria.  I wasn't pressed for time so planned to go there by bike, and it all went well! I took the bike I had repaired a few days earlier, no problems with the repair or the bike at all.

There was some traffic congestion heading into the city, and I made my planned 12:30 train from Southern Cross station to Waurn Ponds with about a minute to spare.  Whew!  That meant I didn't get to the right carriage to accommodate my bike, but I managed to make do with an empty corner of the carriage I got into. All this was less drama than I had on a similar trip 18 months ago: then the side panel of my bike fell out, and I needed to buy more bulldog clips to hold it together!

Navigation from Waurn Ponds was better too.  Turned left instead of right at Ghazepore Road, and it runs almost all the way to Bellbrae, but with the odd gravel section (Ok) and hilly gravel section (get off and walk the front wheel drive leaning trike, no real drama).

Quite hungry by the time I reached Urquarts Bluff, and I wolfed down some left over Thai takeaway, then it was on to Airey's Inlet where I was staying. The bakery (woohoo) was open and I bought donuts, cheesecake and bread.  The donuts were enough to stop the immediate hunger.

After a day or so (I managed to get some surfing in and caught up with a few friends out in the water) it was time to head back, and took a few photos on the way.  The potential roadside free feed this time is the Brassica weed as discussed in a previous post.  It seems to be everywhere from the empty railway land near Southern Cross station to the roadsides of the Great Ocean road, and my pic is of it thriving in a small crack near the Bellbrae roundabout.

Uneventful trip home, with plenty of time for correct bike stowing on the train, I got back quite refreshed.

Tailbox Repair

Trike in for repair with lots of.....

clamps on the back to ensure the glue takes hold.
Inside of the tailbox after repair.  The small brown part in the centre is a splint glued into place as a repair to the split timber underneath.
Hi, after overloading my tailbox about a week ago, its all fixed now.  this involved cleaning its inside, then carefully glueing it back together.  All fixed, this is the 2nd repair to this tailbox.  I have been using this trike as an all-purpose ute, and keeping the one that is for sale on ebay in good condition.

Velocino Continued

Almost finished, this is with the handlebars folded.

First Mission included retrieving a teapot from a junk pile

Overloaded Recumbent

Cleaning up the drill press

Ceres metal, .....

bike tube and bike tyre recycling. Woohoo!
Hi, in the last few days I have fixed up the Velocino and had it on the road for a short test run this afternoon.  This included custom 3d printing a light enclosure and using it to plug the front frame tube. It goes quite well, and I think the above seat steering does a good job, allowing me to lean forward on the handlebars for improved aerodynamics, but its not quite classic Velocino . There is still quite a bit I can do with this bike which is quite fun to ride.  I should be able to make a wooden chainguard and have been working out how to make that in my head.

In other news I visited the Ceres bike shed where they have recycling facilities for bike tyres, and donated a drill press I had bought in Germany in about 1987 to the Wecycle bike shed.  I initially attempted to haul the drill to Wecycle by trike but I only lasted 2 streets before having to return home tail between my legs having broken the tailbox with all the weight.  No permanent damage done I hope.

As at least night...

Fossicking for parts, I used the top stem shown here....

to make this thing, a holder to keep 2 tubes parallel.  Here it is jigged with a couple of extra parts to ensure its lined up before brazing.

End of the day, the handlebars are only sitting in place, but its quite close.

Front view

Handlebar folded which is.....

a copy of this bike which I made and sold in 2012 . It had an ex moulton 2-speed kick back gear.

Lights and 3d printed end stoppers on my recumbent, I plan to make similar for the Velocino.
Hi, not much to say here.  I looked up my old blog posts to work out what I'd done with the handlebars of my old Panasonic folder. Regards

New Bike Part 2

Sawing off the fork lugs.  They were welded in, not brazed, so just heating them up wouldn't have done the job.

Lug removed

New lugs in place

Sawed up Oyama frame.  I decided not to use these parts straight away and make a trike instead, so these bits will go to the recyclers or storage.

Jigging the new lugs so they can be brazed in the right position.

Estimating the V-brake position.

V-brake jigging and checking allignment with dividers

Nasty surprise in the Byk back wheel, the rim tape was soft rubber and not suitable for the hollow rim, the tube was close to puncturing through bulging into the hollow rim.

Trendy Tokyo Bikes in Fitzroy,

.......  and nearby Anchor BMX where I went in search of 451 wheels, tyres and tubes.

Forks and other bits.......

During the painting process.
Hi, I've been progressing with the bike a bit, there are a few photos above.  I scouted out a few likely places for 451 tyres, tubes and wheels without immediate success, but really just wanted an excuse to get out and ride on a very nice first day of spring type day.  Anyway, I did come back with black spray paint and have been finishing off the forks and steerer for the trike (decided to make a trike instead of a bike) as well as spraying the front part of the Velocino.

New Bike Part 1

One of my current trikes with the new fork and front wheel next to it. The lower fork height (green lines) means the new bike will be a bit lower than the old one. I'm interested in getting a 3d printed version of the part squiggled in blue, see photos below.
The stripped Byk Frame.

Clean swap for an 8 speed 40t Sunrace cassette from the old 32t largest cog one supplied on the Byk.
Byk front wheel and forks.
Spreading the fork to take the wider rear wheel, a couple of round tubes slipped over the fork legs add leverage.
Back wheel fits nicely.
Oyama frame and front wheel
A bit of a start I had made on the steerer, here is some detail,

..... and here is the whole thing.
Frames side by side,

..... and another view.
Steel frame weight.

Alu frame weight.
Sketch for discussion with parts supplier. This is the steerer tube and bottom bracket casting, its equivalent is squiggled in blue in the top photo and seen.....

top right in this photo. The new front fork will make the new bike a bit lower (and faster, woohoo) than the old one. 

Trying some steerer tube bearing parts on the steel frame bottom bracket - they seem to fit ok and the steerer bearings should make things a bit lighter compared to bottom bracket bearings.


Over the last few days I have been working on a new bike, as started in my last post. I've been taking apart the Byk bike, and gradually pottering around and planning with the pieces, seeing if they will fit together with other pieces, dragging bits out of the shed and doing the occasional bit of modification.  I came across a 20" folding bike frame and got that out.

Its interesting to compared the Byk frame to the red folding Oyama.  The Byk is aluminium, and weighs about 1/2 as much as the steel Oyama. But the Oyama folds, is slightly bigger to suit adults, and I can weld and bend steel, so do a bit more with the Oyama.  The plan is to saw a frame and use the rear triangle on a new bike and add rear suspension. This is like some bikes I built a while ago.

A few engineers I used to work with make machines which 3d print aluminium, and I went to see them in Dandenong on Thursday.  Its possible I will be able to get some parts from them, so that's a bit exciting too.  Very happy with progress sofar!

Till next time, Regards
