[Brompton] DIY waterproof front bag?

Hello,

"Make Brompton bags" returned a lot of threads… that didn't help, so here goes.

I would like to add my own waterproof bag to the frame.

If some of you have done it, what are good options that don't require serious seamstress skills? Or if it does, I can ask a nearby shop.

Thank you.

More expensive than the T-Bag, so no go.

Hey Winifred,

That's just an example.

If you got to a thrift store, you'll likely find a bunch of laptop/messenger bags with a slide-out for carryon luggage handles.

I'm not sure what it's called--there's an opening on top, and bottom---it's in many "business/executive" messenger/laptop bags.

You could probably find something fairly cheap off amazon or ebay....or in person.

if you got through the part of making the bag, you can make any bag waterproof by using nikwax seam sealant

Thanks for the hint.

Would you have a picture of that kind of bag?

You want the frame to be inserted/sewn into the back panel of the bag cleanly or you just want a way to attach a waterproof bag to the frame?

I have made bags, a quiver and tool rolls very easily using fabric glue and canvas with stitching only at stress points. Any waterproof bag you like can have a pocket for the frame glued on, so you do not need to stitch by hand nor find a sewing machine that can handle heavier fabric. Before I attach a cloth panel the edges are folded in and glued and clamped or weighted down to ensure the glue penetrated the cloth properly. The folded edges prevent unraveling. By the next day it is cured and ready to be glued to the bag. Since it wasn't stitched there are no seams to seal. There are lots of YouTube lessons on how to convert regular cotton material to oilskins if that appeals, but glue the bag together first.

Both are OK, although the former looks better.

Thanks for the tip. Would you have an exemple of one of the bags you made?

I used a small Lowepro camera bag that had a strap to attach to a belt. I used zip ties to fasten it to the bottom and top of the frame. If you're looking for a bigger bag, it's unlikely it would have a belt passthrough but maybe there are rings or other attachment points you could use.
