For my brother's bikes
I took some ideas from this thread http://www.mig-welding.co.uk/forum/showthread.php?t=8247 and also looked at what ones you could buy
Made a few sketches on paper to see what looked best
It's mainly made out of 25mm box (I have loads of it!!)
Tonight's photos are cr@p as my phone camera never copes well under worklights
This is as far as I got on wednesday:
The base done, with a few funny angles to try and figure out, and a start on the upright
Here I'm about to tack the upright on. I've clamped on an exisiting T piece I had to hold it in place:
Lower strengthening brace:
And this is the top part:
I added a brace to the stub sticking out from the upright. There is about 6" of 20mm box which slips into this, with 25mm box welded on to the other end, and I cut into this to fit the piece of angle.
The very top piece is just resting in place to demonstrate the clamp. This is another piece of 25mm box with 40mm angle in the middle of it.
I plan on using an m8/m10 bolt with wingnuts to go through these peices to form the clamp, if you understand?
You can also remove the top peice and slot it back in at 90deg to clamp a vertical part of the bike, and I will make up another clamp using 25mm angle for smaller bits of the bike frame like the seat post.
Once finished, the jaws of the clamps will be covered in rubber or simmillar to protect the bicycle's paintwork.
