Hiya Ladies and Gents,
I hope you might be able to give me a few pointers were I might be going wrong with my Veritas No 80 scraper plane. I have watched Paul’s video on sharpening the blade and followed his instructions.
I have been practising on a piece of Oak, I planed it with a no.4 and it had a lovely smooth surface. I then used the no.80 and got nice thin shavings, no dust. but the finish of the wood felt very rough, like I’d used 60 grit paper. Disappointed I used a card scraper to see if it was just the oak being difficult, the card scraper left the surface smooth like the no.4 did.
I saw there were some machining marks in the blade from manufacture and wondered if this had left a ‘jagged edge’ that was effecting the cut, so I went back to the diamond stones and worked the sides until the blade was smooth. Admittedly the stones are new and the extra, extra fine feels quite course compared to the waterstones I’ve used in the past, so it may be that the blade may need some extra work.
In General should a no.80 leave a very smooth finish to the surface like a card scraper does?
Could using a no.80 on Oak cause this type of problem?
Do you have any ideas to what could be the cause rough finish? Blade prep?too small/large an angle applied to the hook/burr on the edgeDo you have any suggestions on what I can try?
Kind regards
DavidDavid, I’m still somewhat of a novice with my old Stanley No 80. Like any other tool, I believe it takes practice. It sounds as if you’ve properly sharpened. I wonder if you might be tightening the adjusting screw a bit much. Mine leaves a surface every bit as smooth as a card scraper. Perhaps the other members will think of something else. Best of luck!
28 May 2015 at 9:40 pm #127372Thanks Gary,
Thanks for the pointer, I did go from no pressure on the screw with no shaving, to a light pressure and thin shaving through to a heavy pressure and very greedy shaving and at each point the surface of the wood was really rough. I am wondering if it is the prep of the side of the blade, I am going to dig out my water stones and see if they make any difference.
Thanks again.

Thanks, I thought the scraper should leave a great finish, I know what I need to achieve now. I am getting the same result from both edges. Except for the rough finish, the scraper seems to work well with nice shavings leaving a flat finish.
With regard to the hook, does anybody know what the difference a small-low angled hook compared to a large-high angled hook does to the type of shaving you get? i.e. does it give a smoother finish, more or less aggressive shavings?
Thanks again
David29 May 2015 at 11:30 am #127378Hello David,
Sorry to hear you are getting a rough finish. With oak as it is quite open porous, you can sometimes get a slightly rougher finish when going against the grain, particularly if the screw is advanced quite a bit.
The extra fine stone on the sides should be plenty good enough, especially as you burnish the afterwards.
I am not sure I understand what you mean by a low angle or high angle hook. Do you mean how far beyond the 45 you lift up? From my experience, a small hook can give a finer finish and a large hook can give a more aggressive shaving but often doesn’t last as long. That is something you can experiment with.
Hope some of that helps,
Phil29 May 2015 at 4:29 pm #127383Thank you for your replies, it narrowed down the possibilities of what I was doing wrong.
I have just re-watched Paul’s video of where he is creating a hook/burr and see he has a rhythm of (I think) touching down in the first 1/4″ then pushing through creating the burr, where I was striking!!!! the blade somewhere in the middle and creating a dreadful edge. I have just tried from a standing start pushing from one end to the other and low and behold, I am getting good shavings and a nice finish, Hooray!
Thanks again for your replies, I owe you a virtual pint and if we ever meet up I’ll make it a proper one.
Cheers

You must be logged in to view attached files.I’ve had a No80 for a short time and have found that as the hook dulls it gives a very rough surface. Is it possible that you have rolled the hook to far and getting the results of a dull edge? Try lightening up on the burnishing. I am no expert but t this is the first thing that came to mind when I read your post. Good luck!
29 May 2015 at 9:44 pm #127394Hi Sandy,
Thanks for that, I’ll keep it in mind for the future. I have realised what I was doing wrong (though I am sure its not just one thing!!!) I was smashing the burnisher down into the middle of the scraper blade creating divots along the length which was causing the rough finish. As soon as I started with the burnisher on the edge and pushed along, everything came good.
Cheers David
30 May 2015 at 3:35 am #127399That’s great, David – glad you got that figured out. I’ve had a lot of trouble getting my #80 to work properly. I’m quite sure it’s in my preparation of the blade. Practice, practice, practice. And then some more practice.
