Gah! A whole month with no progress on 'the project'.  >:(

At least I made time to do a bit of welding today.  :smug:



I also got the other awkward hole drilled through the other steerer - 16mm dia, at an angle and off-centre, - I now have a left & right handed pair.  O:-)

A bit more progress over the last 2 days:

A couple of wedges are cut from a 2 metre lenght of box section...



...so that they can be closed up ready for welding.

Once welded, some of the bits are set up in place to try to mark where the other end of the box-section-with-the-head-tube needs to be cut.



A bit of sawing & grinding it fits well enough



Before it can be welded in place, it is used to mark a right-handed piece to match.



The best way to check that they match is to put the two together, end to end, to see if they make a straight line.



I'll need to make a jig before I weld this up.

'Interesting' design John. Can't wait for the next installment.

That's starting to look very interesting indeed.  Hope you have time to take it further soon.

Another month without posting progess - Tsk.  ::-)

A few people on the Rutland camping weekend mentioned how much they enjoyed the Wobbly Workshop thread, and as there has only been a little progress on the current project, I'm going to post an old one.  :)

Raw materials



Which gets assembled into this:



Can you tell what it is yet?









... well perhaps with a bit of kevlar wick added, and two more identical ones:



And this is what they're used for:

The current project is going to need a bottom bracket:





I also cut a bit more thread on the steerer tubes:

Continuing with the bottom bracket:

 I have a hole saw that is bottom bracket shell size.  :D





How many of you would dare try that?  :demon:

It's a good fit



They are going to be welded to the bottom bracket shell to attach it to box section

Blimey John, sailing close to the wind on the hold down nuts!
Is the bottom bracket a pinch fit on the main frame for leg length adjustment?
It's coming on.

Here's a quick project:

My new bike camera arrived last week.



I don't usually wear a helmet, so I need to mount it on the bike. As I have already made a mount for my old school GPS to fit a Smart light mount, I thought I'd do the same for the camera.

I took an old light apart...



...and sliced it up on the bandsaw.



After sticking a flat plastic layer on top and sanding, I drilled a hole for a 1/4 Whit thumb-screw.



A bit of thin foam from a mouse-mat colmpletes it.

If it ain't broke, fix it 'til it is...

Is that a Rollei camera, John?
Oh, Bach without any doubt. Bach every time for me.

Yes, as mentioned on this thread. I must do a write up sometime. £50 for a 5M pixel camera with waterproof enclosure, 2" screen 1280 x 720 @ 30fps or 640 X 480 @ 60fps, touch-screen to activate setting, and 4X digital zoom, sounds good, but I had big problems getting it to accept the memory card. The HD setting has good definition, but is a bit jerky with frame rate (this may be my PC's fault). 640 x 480 is smoother motion, but blockier pixel wise. Quality of the camera seems cheap - like the Muvi copies from a few years ago. The waterproof case seems well built but I haven't tested it's waterpoofness-ness yet.

I suspect the Rollei name has been bought up by a Chinese manufacturer (presumably now pronounced "Lorry").

It's worth the £50 but it ain't a match for the Go-pro market.

OK. Time to make wheels for 'The Project'. I've always fancied a disc wheel. :demon:

First I marked out a disc of sheet steel. A strip of wood and a couple of nails makes a trammel.




It's trimmed on the guilotine...



...before being ground to a disc on a homemade jig.  :demon:




I forgot to take a photo of the disc with a segment cut out, but following that, the next job was to dish it to a cone , cold & by hand on the anvil...



...and the join welded up.

Annoyingly I'd miscalculated and it was a touch small for the rim.  :facepalm:



Never mind, it would stretch a bit in forming the flange on the rim of the disc (He said 'flange' & 'rim' in the same sentance!)  :o



Near enough. It will be OK when it's tidied up.

You lot are sooooooo gullible - I can't believe you thought I was making a 16 SWG steel disc to fit a Ksyrium rim.  ::-)

Its for a 26" (ERTO 559) steel rim.



As you can see, I've added the mounting bolts for the knives.  :demon:

Sorry, did I say knifes?...





...I meant legs.  ::-)

It must have been because I was thinking of Charlotte - the thing I'm making is a copy of her fire-pit as seen on the 2013 Rutland camping weekend



The wheel is going to be part of it though. I removed the rim and cut it close to half way and then shaped the ends:




These ends werethen welded up with a M6 nut in line withthe spoke hole.

A threaded hook was forged out of an old worktop joining bolt, and the rim can now be bolted on to take a chain that will suspend either a kettle or grill/grid for cooking on the embers.  :smug:



Sorry to disappoint those that thought I was making a recumbent version of Boudicea's chariot.

As I said, you lot are sooooooo gullible.  ;)
