Device designer Josh Cook dinner and I are making good progress on snaking GoDrilla by means of the CNC delivery canal. (What’s GoDrilla? Learn this.)
We received the aluminum software our bodies and metal nuts manufactured, and now we’re understanding the kinks. There are all the time kinks. I spent Friday morning attempting out 5 totally different hex shafts to see which one we must always select to ship with the GoDrilla (totally different supplies, hardness, producers).
In the course of the testing I managed to lock one of many metal nuts on the aluminum physique of the software. Nothing would break it unfastened. Josh finally instructed a soak in WD40, which did the trick. An in depth examination of the software’s elements revealed that a few of the black anodizing on the aluminum physique had stripped off and jammed the threads.
So we are going to add a manganese phosphate coating to the nuts (which can each battle corrosion and add lubrication). And we can even apply lubricant to the threads throughout meeting in order that they don’t seize.
After I added a drop of machine oil to the threads, the software stopped locking up, even when horrifically abused (see picture above). That was reassuring.
The opposite shocking kink we’re understanding is a few bizarre runout we get once we first put the 12” hex shaft within the physique of the software. After a brief break-in interval, the runout disappears and the software runs insanely easy. We expect we all know what’s inflicting this and have a possible repair so clients don’t should “break in” the GoDrilla.
We hope to have this software out by the tip of the summer time and have it value lower than $50.
Or we are going to run right into a brick wall. Bringing new issues into the world – instruments, books, aprons, furnishings – is sort of a journey by means of the Fireplace Swamp.
