One of the people on another forum posted pics of one, I believe, her father made for her. My Marine made one for me over the weekend while he was home on leave in less time than it took to make a batch of cphp. If the moderators allow I'll post the link (not sure if posting a link to another forum is allowed), if not pm me and I'll give you the link.
I love it - its set to cut 1" slices and is 3" wide so it will easily handle either my loaves or my tubes (pvc). Cuts cutting time down dramatically and was made with scrap lumber and spider wire (fishing line).
