Yesterday I got back from a 2 night stay in Cobram, and fitted in a visit to my Aunt, an op shop, a few bakeries, and a flat Audax 200k ride. It was a long-ride-debut for the new tailbox and fairing-parcel-shelf on the trike, my first Audax for the year, and my first formal training step for the Great Southern Randonee in November. Its not a huge ride given the sort of training I've done, but nevertheless I was keen to get a few Audax k's under my belt before trying something with more consequences.

The visit to my Aunt was great. She lives on an unsealed road about 5k from Beruga, which is in turn about 4k from Cobram. I hadn't ridden out there before but decided to try it this time. And like some previous visits, I overshot her gateway and kept going for a k or two on the jarring road before turning back. A gentleman had stopped in the road to inspect a dead kangaroo he'd hit in his car the day before. He was picking up bits of broken headlight and his car was obviously bashed in. It was a big roo. Anyway, he directed me to Mary's place (not far). 

Mary was with her friend Pat and they were impressed with the trike, so much so that Mary rang up her son David and invited herself and me and the trike over so I could show it to David and his family. This involved me following Mary's car over sand drifts and corrugations for 3k or so. We sat around the table and chatted for a while. It was good to catch up and meet everybody. It was getting dark by the time I left, and David, who drives trucks and all sorts of agricultural machinery offered to drop me back to the made road rather than negotiate the sand drifts in the dark. I gratefully accepted and got to relive my ute riding childhood on farms, grabbing the back rail of the ute with one hand and the trike with the other and riding with David to the top of the hill just after the bitumen began. I dismounted with the trike, and was on my way in the dark, only stopping in Barooga to adjust my seat which had slipped back a bit on the trip. After a pub dinner I was in bed early. 

After plenty of sleep, it was very easy to pootle down to the 7:30 am start. I fell in with Richard who did a steady 25 kph most of the way to Nathalia. Something was irritating my kidneys and I needed to pee a bit so that kept me always playing catchup. Finally outside Nathalia my bottom bracket came loose and needed fixing, and he pulled away for good, and after that I didn't see any other riders.  

But I did ok. It was quite warm, I stopped in Shepparton to have a pie and get my Brevet card signed, then stopped again in Namurkah. After that I was still riding quite well, and when I checked the time realised I could do an overall time of under 10 hours, or 20kph average. So I kept up the speed and was happy with the result.  There were some headwinds but they didn't affect me much and the Garmin did a good job of navigating. I still can't get it to show my speed as I'm rolling, but I'll get there with that or find a workaround eventually.

No real problems with the bike. Things dropped out of the fairing tray when I went over bumps, and I will improve that, and I have found some neobdinium magnets to use as catches for the tailbox hatch and am looking forward to installing them. The seat needs a bit of attention too, like 2 layers of padding on the bum and tidying up a bit.

Next up is a ride from Port Fairy to Anglesea, a tough one, 300k with hills, but I am familiar with the territory, am training on hills, so am hoping for the best. I am thinking that in lieu of steep enough hills, I will just ride up the local hills faster, at 13 or 15 kph instead of 10 kph say.

Tailbox Part 3

Hi, a few photos from yesterday. I finished the tailbox off and its debut ride was at night to Port Melbourne, where I volunteered as an instructor at a bike repair workshop. The speed is impressive as is the light weight. Only problem my tail lights weren't working due to lack of charging!

Off to Cobram for a 200k flat Audax tomorrow.

Tailbox Part 2




Here are todays pics of tailbox building, it has gone well, but there is some finishing to do.

I had a go at building a corflute end for the box and this included some 3d printed parts. As well I filled in the visible construction parts of the back with corflute from a Ben and Jerry's icecream ad printed on corflute.

Plan to finish off the box tomorrow and hope to use it on Saurday's ride inCobram.

Tailbox and New Thingiverse Files


2d cad design for tailbox with scoring pattern at bottom.

Scoring the corflute. A straight edge clamped on the sheet is used as a guide for scoring, and then used for bending the sheet.

Folding the sheet, and using

this 3d printed clamp to form the sheet.

The clamps with screws and a piercing tool made from a spoke.

This arrangement has been in the trike for a while and is...

a simplification and strengthening of ....

previous ....



The pictures show the new bike tail fairing I've been making.  And the spacers I've put on the trike frame have now been written into the plans for the trike on thingiverse.

Hopefully I will finish and test the new tailfairing within a few days as I am booked in for a 200k flat Audax ride next weekend.

Update May 4 2021

With the underside positioned in the right place, I've marked out the top side, so it can be trimmed with enough space left to hold it to the seat.

This tab will be folded over, pierced, and screwed to the seat, 

like this.


Nightshift. Outline of the top of the 'box is cut out now.



Here are the photos of today's building. The bottom part of the fairing is built, and the top is ready for bending and attaching to the trike. For the most part it is for Audax riding where load carrying is not so important, and aerodynamics and light weight can be important.

My planned schedule for rides leading up to qualification for the great Southern Randonee are

May 8, 200k in Cobram, Vic (Flat, hopefully fast, the aero will help.)

May 25, 300k, Port Fairy to Anglesea. (300k, Hilly, aero and reduced weight will be important.)

Jun 19 and 20, 600k Around Temora (GSR Qualifier, mostly flat, the improved aero should help.

The GSR itself is not till November and some more eserious training will need to be done before then.
