you don't need a starrett reference stone t-trees,
Well at least we agree on something Ben.
Technique and observation over fancy tooling any day.
Observation to start off with, and suitable technique will follow if honest about the
observational part.
After all who wants a plane of shame
I have no issue with embarrassment, as I'm not too clever and really should'a known better.
(I have three planes of shame from being ignorant)
I'm sure some might like to see some more horror shows?
I've got a few other things, and some were important!
How about a big lump missing out of my tablesaw pulley from tapping in what I
thought
was a flat key, as I only checked it on both ends because I believed
most of the gurus
talk about lapping, I have yet to forgive myself for that one.
I have some more stuff which I've likely documented also.
The awl is pointing at a hair line fracture, which can happen on an already thin plane.
I don't have pics of the two others, those woulda been worth documentation.
Suppose for the skeptical they could just blame my lap or whatever, unless
they get something accurate and prove this to themselves...
Or just prove it with the passage of time doing various things on something just quite flat
instead.
That might never happen if one has grinders of various kinds and uses them to hollow out the centre, like this gib for instance
(looks a bit yucky as it was the only 5mm plate offcut which was used for drying damp rods)
Couldn't use the grinder for the smaller parts, so they had to be scraped with the chainsaw file.
(I'm not suggesting one grinds their plane, not even with a worn flap disc, as it's likely still way too aggressive and concentrated compared to lapping)
Scraping like Bill Carters method I don't think I'd try again either,
I needed to do this after making my no.8 quite convex, more than a few sheets of paper.
It took an age lapping this correctly to get it somewhat tolerable.
Would have been an easy job to just lap it correctly in the first place, and the plane is only at a state which is tolerable enough to use now, yet with some L-N "style" bias, as I respect the edges so I can actually end up where I want to.
Back to lapping planes though, if one focuses on the high spots,
then it will infact take less time and abrasive than working the whole surface,
That's a waste of time, but significantly more importantly, the work itself.
All the best
