Div inspires me daily. Hence, I embark upon his shoulder plane project. Mads has already tackled the low angle (thankfullly, because I didn’t have the guts), so I will tackle a 25 degree primary iron angle on a 37.5 degree bed. C’mon guys, it’ll at least be informative! Like Div said, first you start with an iron. I’m getting lapped by Mads (who can produce tools magically, upon command) so my sacrifice will be a gorgeous vintage Stanley (sorry plane Gods; and to Paul Sellers, at least it’s thin! :) ). Here she is in the death grip (a Stanley scrub says farewell):
I’m not going to use a quality wet grinder (I’ve gouged a wheel before) to do the dirty stuff. I’m going with the cheapo to get the rough stuff done. Once marked out, I’m going to use a Foredom armed with reinforced Dremel wheels to sketch out the primary cuts. People have commented on the number of wheels Mads went through…if you run your tool at the highest speed possible, you can give your wheel “some” longevity (I started out timid and grinded wheels down so quickly that the vise started butting into my handpiece…Practically, I’d plan on going through 6-20 wheels). I got tired of watching the money burn away…but stay tuned.
Mads commented that you should come short of penetrating the metal to save grinder life and I concur. I went about 3/4-way through, then wrenched the piece off with some vise grips (Dremel discs are expensive, for what you get; forget about the Foredom brand name ones! :) ). I resorted to a thin “kerf?” (thanks for the tip, Div) pneumatic grinding wheel to bring the iron to desired dimension.
Off to the Scary Sharp! I like cheap Lowe’s marble windowsill for my base. For precision purists (StumpyNubs, kidding brother), I’ve checked them with the Starrett and they’re flat.
As mentioned above, I’m going with a 25 degree primary. This deserves the Royal treatment, so I made sure I was dead-on and square before I hit the quality wet wheel. I dressed the wheel coarsely until I got close to a burr, then I redressed fine and reached an even burr
Then to the powered strop prepped with some Autosol (my favorite). I’ll alternate between the strop on the bevel and a quick pass over 2000 grit on the back of the iron until I don’t feel any resistance on the Scary Sharp (it’ll glide like butter). I forgot to mention, I spritz the Scary Sharp wet-dry paper with a slurry of water with a blob of Murphy’s Oil Soap.
Here’s my bevel side. For those of you spotting that gouge, if I live to get into that vein, I’ll be a happy man (smiles, Mads).
Here’s the backside (the “money” side). You’ll have to trust me that that’s just dust, not pits.
Already caught him “hanging out”; for the record, molding planes are a bad influence :)
What can I say, I’m a dumb guy, had to try it out. It’s sharp.
A big hug for Div for motivating people to make irons!
