Two-blades method - possible to improve?
Posted: Wed May 05, 2021 12:03 pm
I tried the two-razor blades method for making thin sections;
It works but is fiddly and I cut myself..
I had this idea to improve it, if somebody has a 3D printer and time/ideas to design it.
It consist in holding the blades at an angle, so the thin slices in the middle don't get clumped, and should be possible to cut thinner sections a bit more reliably.
The 3D-printer object is just an holder to keep the two blades in place; each blade sits in a support, the two supports are connected by braces. Plus a short handle to use the tool. Basically it is like a modified disposable multiblade razor, the main difference is that the blades are much nearer, slightly angled to each other and held firmly so won't flex ad open/close the gap.
It would benefit some fine adjustment method to get the blades aligned and at the desired distance. Using the flexure of properly designed 3D parts may be the way to achieve the fine adjustment.
Just drop the idea, if somebody is interested!
Which blades, I don't know, either the Olfa, or straight razor blades... some standard mount.

there should be some thread in this forum, but couldn't find them
