Re: Filter Baskets
Thanks, nelo.
I went and bought a second sunbeam pressurised basket (so i could keep the original for stale beans
) and stuck it on a lathe to cut the bottom off.
Ive put a picture here for those interested. It turns out that it is not quite as simple as you might think, mostly because the basket has a springiness and as you try to cut into it, it tends to deflect away. As you can see, tried near the centre first, then further out, but finally, it worked best right out near the edge. Also deformed the basket rim flanges a bit using the 3-jaw chuck, so needed to gently tap them back into shape. The things we do...
Yes, Ive backed off on the grind fineness and am now tamping harder. Still get a few grinds, but Ive decided I can live with it.
