I'd buy her a set of paintbrushes and rollers for Christmas, myself!

She does some of the decorating.

I can't be too hard on her -

She has a full time draftsman job, 40 mile commute (often further to site & client meetings) and a two year old to look after.

It's not unusual for her farmer husband to do 15 hour days, 7 days a week at certain times of the year.

Remember the ukulele project?

Well, when the teachers came back, in September, from their summer holidays (while I had been making new benches & shelves for the workshop  >:(), they announced we would be going ahead with the uke project.

This has meant that, in my 'spare time' I had to machine up 60 ukulele kits for the Year 5 students to assemble. It takes about 1/2 hour to do each kit. ::-)

I then found out that the teacher who was given the prototype machined uke kit, couldn't be arsed to assemble it to try it out - so nobody had actually trialled the uke kit I designed.  :facepalm:

Sorry for the moaning.  :-[

Anyway, here's a project from about 5 years ago, that proves even I don't get things right all the time.  O:-)



I need these bits...



...and weld in a bit of additional tube



This becomes the back end of a wobbly chopper Swingbike-a-like  :smug:





It gets a fade paintjob to match my (then) time trial bike.





Trouble is, I got the angles wrong - I've never been able to ride it for more than 10 yards without dumping it in a heap.  :facepalm:


That's actually howit ended up after I 'bailled out'  ::-)

Wot ?  Are you saying there is no Sheldon Brown page on the angles required to make a wobbly bike rideable ?

Shocker.

With a Wobblebike, 'rideable' is just another, additional variable. Your value of rideable probably differs from mine. :demon: :demon:

OK. New project.  :D

I've noticed some of you are in need of a bit of support - some uplift to prevent it all sagging and pendulously oscillating as you honk up the hills.  :o

Today's underwired creation, also aims to keep things pert & shapely.  :smug:

It was when this thread, and this thread appeared adjacent, an idea began to form.

Clare kindly sent me her pizza stone holders that were looking for a use...



...which was bent to shape in the workshop.





Now to attach it to the bike.

an old stem was shimmed to fit the seat tube and a bit of 1" aluminium tube cut to fit in the clamp



Holes were drilled for the wire pizza stone holder...



 ...and then cut into slots after 1" headset threads were cut on the ends.



The threads are to hold the wire rack in place using headset cap nuts (a plastic cap is used as a final cover).



Assembled on the bike, I found the seatpost strap on the Carradice wa too short to go around the stem, so I added a cable tie loop to hold it. I also added a couple of cable ties around the rack and the saddle rails to ensure the rack doesn't tilt back.



The height of the bag can be changed by sliding the stem up or down on the seatpost, and the angle of dangle can be changed with the handlebar clamp and cable ties.

How excellent is that?

I'm glad I didn't just chuck them away.

No good. No good at all.

That definitely isn't wobbly.

A bit more progress on THE main project. You can probably all guess what it is now.  ::-)

Oooh, is there some tilt in those front wheels - to maybe help with the cornering and that?

Nice.

I can't work out if that's even desirable (would it not make the steering inherently unstable, like a bicycle, rather than self-centring?).  I'm not very good at this mechanical stuff.

I'd have thought the best approach would be to get a tape measure and rip off ICE's (or perhaps KMX's, given that that seems to be the style you're going for) geometry as carefully as possible.   ;D

That element of steering would normally be described as a king pin, but I think we should be allowed to call this one a wobbly pin.

Nice.

There should be some tilt (a factor of the centre point steering and castor angle), but is exagerated in the photos on account of not having any headset bearing in the kingpins.  ::-)

Yeah, sorry. Weekends have spent mostly working on Daughter's house & garden and my allotment, while at work (the School) this term, we have had a full inspection, Safety audit and the workshop closed for a week for electrical work.

Spare workshop time has been spent machining old Laboratory worktop into a greenhouse for my son-in-law. I've spent most of today putting it together (Hopefully, I'll get it painted and 'plastic glazed' tomorrow).

'Terrible twos' Grandson has also taken up some of my time as one of his child-minders has just had another child of her own.

Of course. That was going to be my first guess  ;D

No need to apologise; it just occurred to me the other day that we hadn't had an instalment for a while!

Good luck with inspection outcomes etc etc

Today I took a couple of photos of the greenhouse - frame built from iroko hardwood laboratory benchtops, recovered from a skip.  :smug:

Haven't made the door yet and there are a few bits of trim to add.





Yesterday I put another shed up in my garden. As the sterlingboard on the roof had rotted, I used (just to annoy Jurek) Aerolam aluminium honeycomb board for the roof.  :demon:
