Old Stanley's blade geometry

[pompon44]

Hi,

This might be well known, but I discovered today that my old Stanley #8's blade is tapered in length... Only slightly (something like 6.5 cm at the tip of the blade and 6.4 cm somewhere around the middle) but it makes me wonder what exactly "square blade" means in that case. It cannot be square to both sides of the blade, is it ?
I assume this has no influence whatsoever as lateral adjuster can correct that, but well, it kind of wasted a bit of my time : I was trying to correct the "squareness" of the cutting edge, and was not carefull enough to check the blade with the square always on the same side... As a consequence, I seemed to go nowhere :-(
Just an observation...

Regards,

You will find the same problem on many blades, often it's an intentional part of the production process. As you say it's more frustrating than a practical problem, but sometimes the honing guide design forces a skewed secondary bevel which looks bad. I much prefer to use a narrow wheeled honing guide so that the action always holds the edge flat against the stone whatever the angle. You can also use finger pressure to correct slightly, or even work a camber. I use this old Stanley guide on all my bailey type blades. The equally obsolete Record honing guide used a ball bearing - the ultimate narrow wheel!

Thanks for that peter as I have one of the stanley jigs and was never sure how to use it :roll: :wink:

Ah - the least versatile jig of all time! It only works on planeblade with the right size slot!

BB, You mean they make usable bench planes that are not Bailey pattern?:wink:

(chuckle). I get the plane joke.

But I will point out the jig it not usable for any chisel that I can conceive of. It really is monumentally specialised.

Well it does fit L-N blades as well. Anyway I like specialised tools.
Look at "versatile" tools - Stanley 45; expansive Bits; adjustable Spanners; those sets of saws from the 60's with one handle and a wing nut. Ingenious, but they all do a job badly and/or slowly. Plus they inhibit (wo)man's ultimate aim, to own as many tools as possible!
Oops - going off subject.

Anyone who truly believes a Stanley 45 inhibits (wo)man's ultimate aim to own as many tools as possible hasn't looked in my tool cupboards recently...

Cheers, Alf

Peter,

Nice pic, it's a great guide.

Narrow or barrel shaped rollers work best for me 90% of the time.
