Trunk mounts 12 Months ago
|
|
|
I was looking for a trunk mount. $300? That's clearly insane. Absolutely crazy. I can get 1/2" aluminum, trace it, and cut it with a jig saw, rattle can it with a gloss black, and it would work great. And while I'm at it, I could make bag mounts just as easy. Why is it so insanely expensive to buy?

If you can make it yourself, then do it. I make as much stuff as I can. It's fun for me and saves $. Course I can't make everything but I do what I can.  |

So just curious, where would you go to buy the aluminum or whatever your using to make a bracket? I'm looking into buying hard bags sometime soon and have been thinking about trying my hand at fabing something up for mounts...

Sheet aluminum or steel available at mostly any hardware store. Or steal a stop sign, that should be enough metal for at least one side, possibly both. Stencil on cardboard, hold up to the bike and see roughly where it is. Cut and then make adjustments from there.
Any jig or scroll saw can make the cuts, just have to get the right blade for it. I happen to already have a pile of saws like this. Once it's cut, hit it with a wire brush to clean it up. Then some angle pieces and bolts and a flat square to go between the two for a brace and for the trunk mount.
Yeah, it's very do-able to make, but if the mounts were $60-80, I'd just buy it. For $300+, no way.
*In no way am I advocating the theft of public, local, state, or government property.*

You'll want a bit more rigidity than a stop sign!
Here's a good place to get quality metal in small amounts:
http://www.aircraftspruce.com/catalog/mepages/alumsheet_6061t6.php
6061T6 is a good universal use material for making bike doodads. It is weldable, tough, and pretty corrosion resistant as well. Can also be polished readily to a mirror shine with most metal polishing compounds.
They have up to .190" thick. That is just over 3/16. That's a healthy plate with some rigidity, and does not weigh what a 1/2" thick plate would, even if you skeletonized the 1/2" |

Damn after looking at those prices I'm not charging enough for my trunk racks the legs are out of 1/2 inch alum 6061 t-6 and the top is .190 6061 t-6

I agree, a stop sign would leave something to be desired as far as rigidity goes. However if you got TWO stop signs, and then bolted them together with a no parking sign int he middle for the trunk support, the additional rear support should be sufficient, so long as your passenger is not the size of my ex-wife or her mother.

I had heard someone made them but I coudln't find out who. Yours is good for those who already have something, but currently I have no luggage rack of any sort, so Iwould simply make a single piece that went from the mounting points clear to the flat point that the trunk sat on. For that I would use 1/2", it would eliminate the worry of it not being rigid enough or bending in any way. Could be done weld free, too.

OK, if you stack the signs, you will have to laminate in order to get the multi-layer strength!
Aircraft Spruce can get those prices, since sometimes you need a small piece of something you don't have a full sheet of, and can't sell the whole sheet price to the customer, but if they buy a 2 X 2 sheet for the job, it's an easy sell, and you don't have the inventory lying around that you might never use. It is also supplied with Certificates of Origin, or Certificates of Conformity, necessary for use on aircraft, and record keeping costs money at every level. I can get no-cert material WAAAY cheaper, but it is easier to find at AC Spruce!
Hope the info helps. They have rod, bar, hex, and shaped extrusions as well for you DIY types. |
