Star trekking across the universe
Only going forward ’cause we can’t find reverse
Scratch-built and kit cars based on motorcycle power-plants have long suffered from this Star Trekking ailment. No reverse gear to be found.
Some vehicles utilise a separate gearbox for reverse, or sometimes an electric motor for that purpose. Â Others, such as the Peel 50 and the Isetta, had no reverse gear at all, so you had to have a mate handy to push you out of the garage or parking space.
I recently came across a small motorcycle engine (250cc) that has a reverse gear built directly in to the transmission. Â This may seem slightly illogical – you’d have to be some sort of stunt devil to ride a motorcycle backwards – until you discover that the engine is meant for an ATV. Â Doing some further research proved that this same manufacturer (Lifan, a large and very well known brand in China) has a score of engines with reverse gears.
In the interest of maintaining a list of motorcycle engines with reverse gears, here is the start of my list:
- Lifan 162MK-N 175cc. Vertical single cylinder 4-stroke, water cooled, manual
- Lifan 163ML-2N 200cc. Vertical single cylinder 4-stroke, water cooled, manual
- Lifan 167MM-N 250cc. Vertical single cylinderÂ 4-stroke, water cooled, manual
- Lifan 162FMJ-N 125cc/150cc. Vertical single cylinder 4-stroke, air cooled, manual
- Lifan 163FML-2N 200cc. Vertical single cylinder 4-stroke, air cooled, manual
- Lifan 167FMM-N 250cc. Vertical single cylinder 4-stroke, air-cooled, manual
- Lifan 172MN-N 300cc. Vertical single cylinder 4-stroke, water cooled, manual
- Lifan 253FMM-C 250cc. Vertical parallel-twin 4-stroke, air cooled, manual
- Lifan 185MQ 400cc. Horizontal single cylinder 4-stroke, water cooled, auto
Suggestions to add to the list welcome!

Finally, after several weeks of sporadic needle work, the iPad bag is finally complete.
Well, sort of. Â The carry strap is still not quite done, but I want to mark a project ‘complete’ so bad that I’m going to ignore that little discrepancy.
The bag took a little longer than expected, as once the leather straps had been sewn around the outside of the bag I realised that they didn’t line up. This required some expletives, followed by un-stitching and restitching of part of the straps.
I now own a matching set of carry bag and iPad sleeve made from an ex-WWII haversack, and leather offcuts left over from furniture making. Â The bag is much smaller and lighter than a laptop bag, but big enough to hold the iPad, charger,cables, dock, livescribe notepad and pen and various other items I require for business travel.
Following a delivery from Birdsall leather & craft in Australia I was finally able to finish the iPad sleeve. Â My wife was gob-smacked that I had actually completed something, which was probably the best part of this project. Â I just didn’t tell her that the sleeve was done, but the bag was nowhere near finished yet 🙂
The canvas flap (made from left-over canvas from the ex-WWII haversack) was already hemmed, and the corners sewn over. Â The next step was to attach this to the leather sleeve. Â Once that was done the final step was to use a leather scrap as the anchor for the harness post to close the bag.
While I am waiting for some hardware to turn up in order to complete the carry bag, I have been working on a leather sleeve for my new Apple iPad. Â The intention is that the iPad lives in the sleeve, which is in turn carried in the bag.
I started by selecting two pieces of leather and tracing the shape of the iPad on to these, adding a 5mm seam margin on one, and a 10mm seam on the other. Â The smaller piece sits against the screen of the iPad, and the larger piece follows the curved contour of the iPad back, hence it needs to be somewhat larger. Â I didn’t happen to capture any images of this stage – sorry.
The next step was to use some strong waxed linen thread and a sharp leather awl to double-needle stitch the two pieces together using two needles at once. Â Start from the open end on each side and stitch down to the bottom corners first. Â Then insert the iPad and use it as a former (carefully!) when stitching the bottom seam. Â You’ll need to stretch the leather over the curved shape of the iPad to get a good fit.
I then hemmed the edges of a piece of left over canvas from the WWII bag to use as a flap. Â The corners of the flap are also folded and stitched over. Â Once again by hand because my sewing machine skills are non-existent. Â When I get some time I will attach the flap to the sleeve – but another project has come up in the meantime…
With the bag in pieces, the first step is to join it back together again. I employed a great tool here that I highly suggest everyone make use of (if you have access to it) – your mother. My mum is much handier with a sewing machine than I, and we just happened to be visiting 🙂
Here is the bag mostly stitched back together, with an iPhone for size comparison. My iPad turns up tomorrow, so I better get a move-on! Â Shown with a beautiful piece of Andrew Muirhead Scottish leather found on TradeMe. Â Just the flaps left to finish by hand before attaching leather and straps.
On the mission to make the perfect iPad bag there may be noÂ compromise. Â Or something like that. Â So instead of just adding leather to the ex-WWII haversack as it is (the easy way), I just had to make it narrower first (the hard way).
A lot of unpicking later, quick whip around with the scissors, and the bag is ready to be stitched back together again.
This bag is designed to replace my current bulky laptop and laptop bag that I currently use for business. Â It will carry my iPad, iPhone, Livescribe pen and pad, business cards, and perhaps a few other sundry items.
My laptop weighs half a ton. Â Because the battery only lasts 2 hours, whenever I travel the charger needs to come along for the ride, which weighs another 100kg. Â The bulk of the two means I need a whopping great laptop bag, which weights an arm and a leg. The end result is like travelling with an elephant.
So I have ordered an iPad.
Of course, the iPad is a magical device, and so requires an equally magical bag to carry it in. Â One a lot smaller than the old laptop bag.
The bags from temple bags are amazing, so I looked around on TradeMe for a bag the right size and with the right look toÂ re-purposeÂ into my own iPad-carryingÂ creation. Â I found a British ex-WWII pack designed in 1937 that will make the perfect base (’37 pattern webbing small pack, or haversack).
On a recommendation from a friend, I hired a stripper. Â A cheap stripper.
Now, you would think that a cheap stripper would do a nasty job, but this one had no problem steaming up the windows. Â Even the wife was impressed. Â She had a go herself.
I am, of course, talking about a wallpaper steamer/stripper. Â At first we spent way too much time fruitlessly scratching at the wallpaper removing tiny scrap by tiny scrap. Â The steamer, on the other hand, made amazingly quick work of the job. Â Next time there will be no hesitation – $28 well spent.
I often wonder about fashion. Â What is fashionable now will look dated in a few years,Â appallingÂ in 10, hilarious in 20, and be right back in fashion again in 30. Â At least for those of us that don’t have vivid memories of it – Remember the 80’s anyone?
Paying homage to fashion over the ages are the various layers of wallpaper lovingly applied over the decades, and brutally removed by me:
Electricity has it’s attractions. Â Electric motors output maximum torque from 1 RPM, so you get maximum power from the get go. Â This meansÂ accelerationÂ off the mark, even if the vehicle doesn’t have a super top speed (well, not all are slow). Â Electricity can be produced cleanly, especially in New Zealand, where hydro power is our major electricity source, and wind turbines surround the city in which I live. Â Electric motors are also extremely quiet, and produce no pollutants.
Unfortunately, electricity also has it’s drawbacks. Â Range is a big one, especially in New Zealand where population density and terrain mean things tend to be far apart. Â Charging a battery also takes slightly longer than filling your average fuel tank.
However, sometime it just makes sense. Â Take the Italian Pasquali RisciÃ³ as an example. Â A shade over 1m x 2m and only 1.5m tall, one- or two-seater options, 40km/h top speed and a 50km range. Considering it’s meant for urban commuting, this is quite ideal. Â Even the 8hr (ouch!) recharge time isn’t too bad if you can just plug it in over night.
My own project won’t be designed to run on electricity per se, but since it will be designed in such a way as to allow a wide range of power options I can’t rule out someone else being crazy enough to try it in the future.

Every project needs a plan, even if it’s just a sketch on a napkin.
Here is my design for the TV cabinet I’m making. It has been drawn up using Adobe Flash, to scale, so that if I need a measurement I can just click on a line and it tells me exactly how long it is. handy!
The middle section contains two shelves for the DVD player and Freeview unit, fronted by tinted glass doors. Â On either side of the doors are what appear to be two drawers. Â The lower drawer in fact flips forward to reveal a shelf for a game console, making it easy to keep controllers and other cords tidy. Â The upper drawer is just a drawer to hold DVDs and games.
