| The pack took about 90 minutes to make in total, from measuring the frame to strapping it on. |
After finding out how convenient frame packs are for carrying things, I had been wanting to construct packs specifically sized to other bikes. To this end, I put together a simple top tube frame pack, using materials that I had on hand for this first tester example. The pack is made of about 1/2 yard of cordura pack cloth that's been in my sewing kit for 20+ years, an old steel YKK 19" zipper, various scraps of Velcro, and some 100% polyester upholstery thread. I didn't produce detailed instructions, but if you are interested in building a similar pack, it's a simple process if you have at least proficient sewing skills. The design is essentially a box, shaped to fit the inside of the frame, with a zipper installed on one side.

| Cardboard template for the frame pack. |
To begin, I took a piece of cardboard, a pen, and a utility knife, and constructed a template of the inside of the front triangle of my 2002 58 cm Surly Cross-Check. The cardboard template guides the shape for each side of the pack. I made sure to mark the locations of cable stops, housing, bottle mounts, etc. so that the Velcro straps cleared them. To connect the two sides of the pack, I used strips 3" wide. On each piece of fabric cut for the project, I added .25" all the way around to account for the seam edge. I also constructed a flap over the zipper, to help protect it from rain, etc., though this pack is by no means waterproof.

| The pack easily holds my trusty Stanley cook pot with enclosed pop can alcohol stove and fuel, among other items. It's big enough to be useful for a picnic, a camp outing, or a small grocery trip. |
The pack turned out fairly well, and fits the frame exactly as intended. The design worked well for fabrication, though I won't use the same materials for the next one. The cordura material is quite sturdy, though it's not nearly as light or water resistent as similarly sturdy modern materials, such as Dimension Polyant X-Pac. The steel zipper works well enough, but it's heavy, and its action is not as smooth as plastic. A modern water resistant plastic zipper will be part of the next pack I make. In the end, I learned a bit about how I'll make subsequent packs.

| The pack is not wide enough to get in the way of riding. |
 |
| The right side has no zipper. |
 |
| The left side has a zipper. Why the left? I'm left handed. Make your own pack how you like. |

Awesome job. What kind of sewing machine are you using and is it strong enough for heavier materials?
ReplyDeleteThanks, John. I've got a Necchi brand model 3354 sewing machine that I picked up used off of Craigslist a while back, for about $50. It's a mid grade consumer level machine from about the mid 1990s. I like it because it's made of steel, mechanically simple, and has a good range of adjustability. It seems as though it would be up to the task of sewing much heavier material than what I've put through it so far.
DeleteI've sewn quite a bit on and off over the past couple of decades, making outdoor equipment of various types. I've only ever used inexpensive, standard machines, and found that if they are in good repair and well oiled, and if I take the time to get to know them, even basic sewing machines are capable of a lot.
I just put in an order last night for materials for a partial framebag for my Cross Check and a full framebag for my Stumpjumper. Thanks for the encouragement. I sprung for VX-21 and waterproof zippers, hopefully it hold out a little Portland rain.
ReplyDeleteGood call on the VX-21 and waterproof zippers. I'll be doing the same for my next one, even though rain is not much of a problem most of the time here. Enjoy your project!
DeleteHeh. I've been looking and looking online for the exact top tube bag and colour and for what ever reason, it never dawned on me to just make it myself! Think this is my next project after getting some rear saddle bags installed.
ReplyDeleteIt's a simple project and quite satisfying to make your own gear. I highly suggest giving it a try if you have the inclination.
