The 3ski from New Zealand take this blog into uncharted waters as the first SkiTrike to be featured.
It has a number of iinnovative features that take it out of the league of toys and into the realms of full grown all mountain vehicles. For example, unlike a toboggan, you ride in a semi-standing position, furthermore the rear skis are ingeniously linked to automatically carve by pivoting together, lastly 160mm long travel forks with 32mm Stanchions and 20mm thru axle ski mounts control steering.

Building a Bike (and SkiBike) Shed

Posted: Sunday, 3 July 2011 by Mark Kinnon in Labels:

My bike collection has been growing recently, consequently it has become a pressing need to get the bike projects out of the main garage to allow for some working space. I find it really annoying to start scratching up your last project, whilst working on the next one.

Luckily, I had this patch of paving behind my garage measuring roughly 5' x 8', it had housed a small tool store sized shed previously. This was cleared, then dismantled and moved further down the garden, putting the garden tools much closer to where they would be used.

The tool store had been from Southern Sheds, who were local at the time of purchase and make
very good quality, but expensive products. I had considered putting in one of their off the shelf items, but pontificated due to the cost.

Luckily a new neighbour, who had been tipped off about my reputation for recycling and general shit hoarding had about a dozen 3" x 3" fence posts and lots of chainlink fence sitting on their driveway to dispose of.

I was inspired to get creative and build something custom.

The posts were all quite new, with no rot. They did have a whole mess of chainlink fence stapled to them, so my first task was to seperate them. About 5 hours work later the job was done.

I made the two longest sides with the posts, and joined them with 2" x 3" rough sawn tanilised timber, all bolted together with exterior M10 coach bolts.
I cut rafters from 2" x 4" timber and made the mortice joints so that they would lock into place on their supports. The ends were cut with a mitre saw to a 10 degree angle for a tidier appearance. The site is near the top of an exposed ridge and the wind can occasionally blow down the valley with great gusto. For extra security the rafters were screwed down with 3" size 8 countersunk screws. At this stage I took the opportunity to give the woodwork a couple of coats of "proper" spirit based wood preservative sourced from Wickes. It looks a lot like creosote and I hope it works as well, just without the cancer risks.

I fitted an 18mm plywood sheet roof and covered it with Wickes self adhesive roofing felt. This is quite a costly option and is fiddly to install, but looks very tidy and lasts for years. The garage had this type of felt applied around 1998 and is still holding tight, no leaks or maintenance required yet. The underside of the plywood was finished in Trimite paint prior to installation, this is the finish used on rock and roll touring speakers and has a slight texture to it.

Clear corrugated roofing material was used to make the window, screwed to a couple of long battens. The lower batten was made from two pieces joined to make a L section. This stops any bowing and also doubles up as a handy shelf.
Incidentally, the battening was provided by another neighbour having a clear out, it had been in their garage for years. The bits stored on the floor had fallen prey to wet rot, but the rest was lovely seasoned quality timber without excessive knots or warping, so unlike a lot of modern wood. There was enough left over to make fascia boards, the door framework, door shuts and the frame work for the infill panels.

I made a few minor modifications here and there as part of the ongoing process, then installed a couple more fence posts as supports half way along the rafter span.
I had a huge amount of 6mm plywood saved from a company's bonfire a few years ago and painted it in white texture stone paint to match the existing garage structure. Battening was screwed all the way round the side appertures, to which the ply was tacked with a nail gun. Ply was also fitted on the inside to form a double skin. The side facing the neighbour was more difiicult as access from their property was marred by a hefty 12' drop, prolific foliage and a fence. To get around this issue I made up the panels like a theatrical scenic flat, offered them into place before screwing the battening down, then finished the interior as per the other side.
Lastly, I built a door utilising some re-cycled exhibition laminate flooring for the exterior and more 6mm ply for the interior. I realise the flooring may not survive the elements long term, but I'll cross that bridge when I come to it.

In order to organise my retro collection as efficiently as possible I wanted to hang the bikes vertically. M10 screw eye bolts were fitted through the roof rafters, with metal plates both sides to protect the wood. Onto these jumbo S hooks were hung. I threaded old narrow section inner tube onto the S hooks and cable tied them in place, this should prevent any chance of them scratching the rims.

Then it was time to install the collection and relax a little.
