DIY topbox rack

Fair enough. I can't say that I was particularly wounded by it, but thanks for the clarification.

:edit: In other news, my phone has lunched its SD card, so when the new one arrives tomorrow, I can show the conclusion to this little project. At the moment, the topbox is happily attached to my bike. Given that the rack came with it, the topbox was a freebie, and the plate is mare from materials I had lying around at work, this whole enterprise has just cost me the grand total of £4 for the coach bolts I used.

I am a happy camper indeed.

Back to business.

last time you guys saw this, I was working on the premise of using two plates in a horseshoe shape. This had been subsequently disregarded as a result of the final material being heavy as hell. it was also massive overkill to my mind, so I elected to machine out some clamps, and use those instead.

This produced these:

Which in turn became these:

That eventually did this:

With their powers combined*...

From above, the plate looks like this:

While I have no doubt that my critic will be deeply unimpressed by the lack of manufactured metalwork, it does the job admirably. I also included the holes around the edge because they make for a most useful set of bungee attachment points.

The topbox that I received was a) filthy on the inside, and b) required some minor tweaks to fit properly. Most of the filth is just old dust/lint, but there's also a lot of congealed/dried brake fluid, which I'll have to get round to cleaning out at some point. Can't say that I'm in a mad rush to do so, because meh.

I had to cut away the original plastic locking point, mainly because it was already a bit damaged, and I didn't know the exact shape of the original corresponding pin - while I could guesstimate it to a point, it wasn't accurate, and didn't quite work right.

That bit of threaded rod that was sticking up from the plate is the locking point for the base of the box; the 'knurled nut' that I'm using at the moment is a holdover from a different thing that I made some time back: I'll most likely 3D print a nicer one at some point (when I've cleaned up the box and such).

And so we come to a finished topbox rack:

If you guys want, I can also put up the original CAD work that went with all this, and give a clearer explanation of the working process for the routing.

*No Captain Planets were harmed in the making of this topbox rack.

Looks good digestive bikkit hiding in there plastic looks like good stuff. How heavy is the final item?

[nowhere.elysium]

Weighs about a kilo and a half, all in. Not a massive amount, but it's about 50% heavier than a bought one. However, this cost me near enough sod all.

Makes my DIY top box mounting system seem massively under-engineered by comparison...

I like it. Does the job, for minimal cost and the added 'i made that' feeling.

I had a complete rack made up from drawings for my zrx. Paid for the ally, but the waterjet machine used to make it was more of a favour

Ill post pics of it once i take the top box back off it.

Nice job.


Critiques corner:
If it were mine I might well have used a larger radius on the corners which would shave off a little of the weight and make it slightly more aesthetically pleasing on the eye!
(Those clamps seem a little 'agricultural' in their finish, is that normal or did the cutter need sharpening?)

I don't understand how on a forum mainly used by men, how making something rather than buying it is questioned? I might be biased though, I spent two shifts at work last week making a flywheel puller that can be bought for £15

Rack looks good, I work with automated production machinery for a living and bodge bits of metal in my free time but its nice to see different materials and methods used.

Any excuse to use 'toys' in the workshop is reason enough for me

Having been pointed to this thread from another, it has given me a good amount of inspiration. Top work.
