Homemade stainless decaleur
I decided to make a simple decaleur for holding a Swift Industries randonneur bag for my Schwinn Sports Tourer build.
I didn't want a steerer-mounted decaleur, nor do I need a quick release. I was going for light weight and simplicity. So I made a stem bolt mounted one.
0.080" stainless plate cut down into a tab for mounting under the stem clamp bolt.
Bending 3/8" OD 0.035" wall stainless tubing for the extension.
Gotta make 2.

Cut to size and TIG welded to the tab. Not a pretty weld but it's a pretty weird joint. Might sand it down more later. I also drilled a hole for the stem clamp bolt.
Now with M6 threaded spacers welded onto the ends of the tubes. Wing nuts will secure the bag to the ends of the decaleur's arms.

Need a bracket to have on the bag to reinforce the area of the bag that gets bolted to the decaleur. Scrap aluminum sheet from work get cut down in the mill.
Brackets done. One for inside the bag and one for outside. The inside holes are for an M3 bolt and nut to secure the bracket to the bag, and the bigger outside holes are for the wingnuts to bolt the whole thing to the decaleur.
Brackets mounted on the bag.

All put together. The rack is the Dia Compe ENE front rack that mounts to a centerpull brake.
Inside view. Might get some rubber caps for the M3 bolt ends so they don't mess with the bag contents.

Well done! Your black bag is very similar to the vintage blue Bridgestone bag I run on my '71 Paramount. Very nice!

Fantastic minimalist decaleur. Impressive fabrication also. I really enjoy seeing people seeing what people come up with for this simple device. I took a similar approach with mine, but it's completely different...

Is that ENE rack strong enough to hold anything? I have one as well, but haven't really given it a chance. I'm just picturing the rack starting to sag, the decaleur starting to bend, and when the handlebar clamp bolt breaks, i lose control of the bike... and I hate it when that happens.

If the load in the bag is too heavy, the bag is more likely to break than the stem bolt, decaleur, or rack. Unless I'm putting bricks in there I doubt I could ever break the bag or the supports.

Home made, well, with above average home tools and technical skills. Very nice. It is good to see these kinds of projects.

Nice and simple! A lot of people rarely take their handlebar bag off the bike, wing nuts make it "quick release enough".

Neat, tidy, simple. And inspirational.
Makes want to get out my propane torch, Alumaweld sticks and rod stock and start fiddling about with all that again. (But I should really get around to making a couple front bags like I've been meaning to. )

Thanks for all the kind words all. I'll update the thread once the new wheels are built and I can test ride the bike with the bag.

Caps for the M3 bolts... just machine them to length...paint the raw metal ends red to go with the shock cord on the bag. an excuse to buy another tool, a lathe.
Those tools look too fresh... (I know they all start that way)
I have not seen that Rigid tubing bender, pretty nice. They do some decent design work.
I bought a Rigid belt/spindle sander that I like very much, don't see it on the store shelves anymore...

Cool solution ad nicely executed. The only potential pitfall I can see (based on my luck), is having something get caught on one of the wingnuts.
