Clamps or vice (optional but suggested).
Mill (optional).
Prior to you start, fasten the spade safely in a vice or utilizing clamps (connecting it to a table or workbench is best). Position the spade horizontally with the front of the blade dealing with up.
You don’t want the spade to walk around as you sharpen the blade; movement makes it challenging to keep the right angle as you file and can result in injuries. If you don’t have clamps or something to attach the spade to, employ a helper to hold it securely in place as you work.
Next, ensure that the spade is rust-free. Why? Because submitting a rusty surface will dull the file.
If the spade is rusted, get rid of the rust initially by scraping, then follow up with steel wool. For a greatly rusted blade, attempt utilizing a wire brush connected to a drill bit– it’ll make quick work of removing rust from a large area. Constantly make sure to wear shatterproof glass as little bits of wire will often fly off the brush!
When you’ve eliminated as much rust as possible, apply a light layer of oil or artificial lube like WD40, Tri-Flow or Boeshield T-9. This will assist avoid or decrease even more rusting.
Now take a look at the company edge of the spade. If so, the finest alternative is to use a mill to quickly whip it into shape. If you don’t have a mill you can still sharpen the spade utilizing a file– it’ll just take a bit more elbow grease.
Utilizing a Grinder to Sharpen a Spade– You have a couple of options here: a bench mill (a bigger grinder that’s firmly connected to a work bench) or a hand-held mill (attempt this 4-inch angle mill). Either will work well when utilized with a medium-grit aluminum oxide wheel.
Always wear hearing security and goggles or other eye protection when using a grinder. Make sure that the stimulates coming off the mill fly towards the shovel, not towards you!
A mill will leave a rough edge on the spade that should be retouched with a mill file as described below.
Type of File to Use.
Files from Corona.
These are the mill bastard files I utilize. I choose the 8-inch length as it removes more metal with each pass.
You’ll require a 10 to 12-inch bastard mill file (see sidebar for a description of what this indicates). The secret here is that it has a broad, flat edge with a reasonably rough, single-cut pattern of teeth. This enables you to eliminate adequate product with each pass but without exaggerating it.
In basic, single-cut files take more effort however enable more control, while double-cut files remove more material with each pass and are best for rougher work.
There are many brands to select from but the one I use frequently is the 8-inch mill bastard file (with separate deal with) from Corona. Constantly put the deal with on prior to using the file!
