I thought I'd try a Japanese joint!

I've had a bit more time to dig into that pdf, you've now got me wanting a copy of Cecil Hewit's book.  There are some British joints the equal of Japanese fiendishness in there.  I may be coming back to some of them soon.  Looks like a lot of b****y hard chiselling involved though.  Need to find the belly brace to clear out some waste with, now is that in tool-box 1, 2, 3, 4, 5 or six, or is it on a shelf, or behind a doo-dah?  I was thinking of a stepped-wedged scarf next, which seem virtually identical, whether British or from Nippon.   Then the "top-splayed and tabled scarf, with sallied and under-squinted abutments" looks interesting, even the name gives me the shivers :bugeye:.

Green Oak is so much easer as it dries Oak gets harder until after a hundred years you wouldn't get a screw in it .

Well, the BBC were right and wrong.  The Hampshire Monsoon resumed, then it stopped and then it got sunny.  I had to take the “apprentice” to his doctor (he goes private, we’re NHS, must have a look at that contract!), but managed to get an hour of butchery in.  I checked the uncut bit of wood to the cut bit, noticed a couple of miscockulations and attempted to uncockulate them, must take more time marking out.  I put an extra couple of lines in to carry a joint around an end, then I ripped down some lines;





…cross-cut another and cut what I could for the dovetail housing-holey bit;



…then some bashing and paring with the chisels;



….which I’m occasionally getting the hang of.  And it looks like the female part is coming together;



Nextly, I carefully matched the two sides up and carefully, gently pared at the tight bits………and then got a bit too carried away;



….leaving some gaps you could park a Routemaster in, to be specific, I think you could get an RML lengthways in some of ‘em.  It was getting late and I was obviously over-tired so I stopped.  The sockety-holey-dovetail bit wasn’t finished, leaving the top proud;



..and I was having issues clearing the corners;



…so I’m thinking of “Mullering” up a couple of smaller chisels to make a pair of skew-wotsits.  I’m sure they’ll come in handy.

Tell me about it.  I did a green oak course a few years back, and I've had ice cream tougher to cut into.  Even further back I was making a replacement sill for a window out of 200 yr old oak, with a blunt plane, I shan't tell you how long that took :bang:, nor the naughty words I was using :palm:.

I think I’ll call it a day on this, any more effort and I’ll bollix it up more.  First thing I did was hunt around for a couple of old Stanley chisels I’ve got to make skew-wotsits.  I eventually found this;



….which seems to show no improvement and possibly some regression in the past 5 years.  Stanley seemed to have taken his chisels back, so I ground out a couple of my smaller Bahco chisels;



…looking at the rust on them, and the edges, it looked like I’d never used them, which probably means I’ll definitely need these with square sharp bits any minute now.  Bish bash Ouch (oh, you're supposed to keep the other hand behind the sharp bit are you?) Bosh and I’d done as much b*****ing stuff up as seemed wise.  The joint was flush(ish) and tight(ish), but if you look carefully into the gaps you may see some headlights in the gaps from a bus or two;







… it definitely looks better from this angle;



Lessons learnt; don’t make Japanese joints out of seasoned oak; I need to make up a square “paring block”; I need lots more practice; I need to take more care marking out; pare and compare, pare and compare, not pare, pare, pare, pare, compare “oh b****r”.

Hope you found this one interesting.  I’m going out for a walk with t’ “apprentice” and he’s carrying the chestnuts back.
