When trying to teach raw apprentices I've always started them on "training wheels" (Eclipse 36 jig or a snide version of same) so they gain an understanding of how sharp they need to aim for. Once they understand that and are getting consistency they can be weaned off the jig onto "figure of 8" honing. The problem these days is the omnipresent cordless tools which have made a lot of hand tools redundant for these lads who often don't understand the need for hand toolsIt takes a lot to beat the old Eclipse 36 honing guide.
I did a lot of work site fitting stuff made in the workshop and yes used planes a lot: 5 1/2, 220, 78 etc. 78 is actually very versatile and useful besides its nominal use.It would be interesting to get some input from site Joiners, as to whether they use a sharpening jig or not, I'll almost guarantee they don't, but then again does a site Joiner even use a hand plane anymore? Apart from maybe a block plane as a finessing tool for sharp edges etc.
Similarly with Bench Hand Joiners, Cabinet Makers, Fine furniture etc, again I'll wager it's all done freehand.
Nothing wrong with a jig like the Eclipse 36 as a training tool as @JobandKnock says. I have one, use it once a blue moon for trueing up, but it never comes out when a blade needs sharpening.
That would fit under the banner of Shopfitting? But yes I take your point, and the 78 is indeed a very versatile tool.I did a lot of work site fitting stuff made in the workshop and yes used planes a lot: 5 1/2, 220, 78 etc. 78 is actually very versatile and useful besides its nominal use.
Mostly period restoration - sash windows followed by window boards, architraves, sometimes shutters and panelling. Doors etc and so onThat would fit under the banner of Shopfitting? But yes I take your point, and the 78 is indeed a very versatile tool.
Site Joinery I would term as to be House bashing, 1st and 2nd fix, price work etc, or at least it is/was, I got out of that particular game donkeys years ago, hated it with a passion.
Not forgetting "Micro-Bevel" & "Charlesworth Ruler Trick" © Rob CosmanThere's such a lot of detailed description of "correct" methods - mainly from magazines, very little in books ancient or modern. The "correct" methods even have their own terminology; "primary/secondary"bevel etc. Difficult to shake off and discover that rounded bevel perfectly OK etc.
