What's next, making your own lye?!
I actually did look this up to see if there was a sensible way to do this cheaper with stuff I could find easy.
There is just barely room to lay the soap on the side, I might try that.
That might work better them my way. I also thought of just a box with a knife guide as the knife I used worked good, all but control of the straightness that is. I saw the single cutters also and was thinking does a multi cutter for just 7 bars really save anything. It was interesting to do though. I like what you posted though I think I might cut my soap a little softer and so stickier. Good luck with your request.
You may be correct, I will know more later. It was easy to do and so would be easy to add to. Believe me, I am offensively simple.
Back to zing
I am not a wood worker. I do most of my cutting on things I build with a chain saw. I cannot do stuff that takes more then two days from start to finish and if it needs sanding, I am out. I envy people with legitimate patients and skills. I do not understand making stuff square and am a slob. Where I do excel is making small junk that is sorta functional using stuff laying around and not having to go to the store and buy it. Most times (knock on wood) I get lucky. I made the sawmill out of a garden tiller and one of those station weight sets. I knew it was the only exercise I would ever get from myself out of a weight set. Just like soaping, I had to join a forum to work the bugs out of it but did build some things with it. I also got really bad grades in shop but leveled it out with bad grades every where else also.
