A Thicknessing Technique

[Harbo]

What I was trying to say was that the "rough wood" they bought was very useable without much preparation (thicknessing included).
I buy a lot sawn timber but it is so rough I could not do too much with it without putting it through a P/T?

I tried this today (it was new to me) on a piece of old pine, partly as a test of the new QS #6.

It was a great success in all respects. Having flattened one side and gauged around I chamfered at about 40 deg with the QS 9 1/2 to take the top off the gauge line. The piece had quite a variation in thickness so the chamfers were significantly tapered.

I roughed down close to the line with a wooden jack and found the guide from the chamfer very easy to follow without peering around the piece. I then changed to the QS #6 to clean up down to the line. Without going overboard the finished board was within 2 1/10ths mm.

Great to learn a new skill, even if half the world knows it already, so thanks Derek.

I don't think the chamfer technique is widely known - the OLDTOOLs list is a very unusual place!

Hi,

Christof Hartge describes this technique in:

Die Zähmung des widerspenstigen Bretts - Teil 6 from March 7t.2004

http://www.woodworking.de/schaerfprojekt/brett1-5.html

I'm pretty sure it is an old technique but isn't that what it's all about? Learning old techniques with old tools?:lol:

Cheers Pedder

An you can bet your bottom dollar that the Romans were doing it too!

Totally agree with you pedder, I see the Internet and forums such as this as being the virtual "grandads" of the modern world....teaching us all old tricks which have stood the test of time.

I think if we all knew all there was to know about our interests then we wouldn't bother coming here at all.

Chris Schwarz does not use it in "The Joiner and Cabinet Maker" but he does scribe a gauge line to work to.
He does use a "British" trick of chiselling a Vee trench to aid sawing to a baseline - "clever Brits".

I practically fell off my chair when I read that, Rod - not often you see that in print! I have a feeling it might be a Hayward tip. Must admit I've never done it - must be a stupid Brit. :lol:

Tried this technique yesterday, chamfering to the thickness line, and it worked wonderfully.

The only additional thing I did was to run a pencil lead along the edge to highlight it. Just made it that much easier to see in the heat of planing.

Thanks Derek!
