no if they made big enough spring like the volutes,,, you'd push the basket down, then hook up some sort thing where you could pull it up, and instead of need a third hand to slip something underneath the springs would just pop out and you sit the basket on the rim....this is the thread where said you needed a third hand to get the colander under the basket/bag right?
Getting the colander under the basket is relatively easy. I only need my 2 hands for that--lift the bag with one hand, place the colander under it with the other, lower the bag. What I need 3 hands for is the next step--holding the bag in place in the colander, squeezing it, all the while keeping wort from running over the sides. Having the right colander or similar vessel to better envelop the bag of grains would make the process more manageable.
