How to make a chalk pot?

Hi everyone

I have seen a few climbers in CT with homemade bouldering chalk pots. Just wondering if there was any website where I could go to find instructions on how to make one, I couldn’t find a website. Any local knowledge would be much appreciated. :thumright

Thanks
Andy

Dude,

A chalk pot or bag is a sack with a furry lining. Quick work on a sewing machine. Put some stiffening at the throat to keep it open. I have seen several variations on the theme - eg Warren makes his out of scraps of climbing rope sheath.

But since you asked: this should sort you out.

My girlfriend recently made me this awesome chalk pot. The design is quite simple, basically four bags inside of each other:

- The outer bag is some kind of tough material to prevent thorns and tears and such things. Denim would be a good choice. A pocket and brush holder can also be stitched onto this layer.
- For the next layer, we used a 4L Sea to Summit dry sack (make sure you get the round bottom one). We chose to use a proper commercial dry sack because the closure mechanism is much nicer, and it won't leak chalk.
- The next layer is some kind chalk proof material. We decided on having this layer because we didn't want the fleece to go all the way up and chalk your arm. This layer must be a tight enough weave so that chalk cannot go through it and get stuck between this layer and the dry sack.
- The innermost layer is fleece. Chalk sticks to the fleece and makes it nicer to chalk up. We used special fabric glue to glue the fleece in so that chalk wouldn't get trapped between layers.

I'm don't know the details of how to sew it all together, but I do remember a key idea being to only stitch through the dry sack in one place. This chalk pot design isn't the cheapest (R150 - R200), and I have seen much simpler variations on the dry sack closure system. One of my friends has a pot which is basically just two rectangular bits of denim stitched together with some buckles on one side to make a dry sack closure. Another friend has a similar pot, but chalk escapes the fabric and you are greeted with a massive puff of chalk if you smack the thing. As for different closure mechanisms, my experience is that zips and drawstrings eventually break or become really difficult to open. The ones without moving parts are the best.
