Any question answered...

I've seen some online calculators but none quite right

given a rectangle of 1240mm x 1020mm what is the biggest box I can cut out of this - ie 6 faces. Presumably there will be more than one box that fits this space.

Has he tried Sportstracker?

Do you want the biggest volume box? Maybe maximum volume allowing 0mm² waste? Probably different answers.

You could do 510×510×365 with no waste (minus a bit for sheet thickness)

. 510
+----+--+--+
|    |  |  | 510
+----+--+--+
|    |  |  | 510
+----+--+--+
.     365×2

Sheet thickness and Kerf (thickness) of Cut?

It did!

cutting out of material, so sheet thickness almost zero, but I will need to take into account some hems.

Id like the 'front' and 'back' to be at least 600mm x 400mm

Paper and pencil is probably the best method, i was hoping for a website to plug some numbers into

It's always worked for me when screenlocked. There really aren't that many settings...

What's up with this bottom bracket?

It has an eccentric adjustment

I think it may be a GT i-Drive suspension set up. I don't fully understand it, but the idea was to allow the BB to rotate within the shell to work with the various forces and changes in geometry brought about by the suspension moving.

Thanks @gbj_tester and @Landslide!

Would it be a good idea to get a sticky thread in the classifieds for free bike/wheel boxes?

There's loads of threads for single boxes and get the idea a master thread would be useful. @Velocio What do you think?

Create the thread, populate it with info... if it's good I'll sticky.

What's the reason for the lack of covers for the bb? The concept doesn't seem that crazy after some reading.

Where can I find these:

I think they're M8, approx 50mm, with a little protruding bit to stick in a notched recess.

SJS probably

Is very often the answer.

Brilliant - Thanks.

Turns out that I have a few similarish in my odds & sods bolt box from an old dalliance with rebuilding 50s bike up.

Did someone on here paint a pink and black crackle paint job? If so does anyone have a link?

Well, it's a clever bodge to limit the problems otherwise inherent in a URT, but it introduces a whole new set of problems to make up for it.

In theory which is stiffer: a heat-treated 26.0mm bar or a non heat-treated 31.8mm bar?
