Creative Man Bevel Jig
The Creative Man bevel jig is designed to make the blade grinding process much easier by helping control the angle and precision of the grinding operation. To use this tool, fasten the unground blade in the grinding jig and move the low-friction nylon bottom plate across the base platen of your grinder and against the abrasive belt until the desired blade grind is achieved. With this tool, producing a quality, precision grind is a much simpler process.
Note: This bevel jig for use with the Creative Man File Guide
The Creative Man bevel jig is for experienced makers who already own the Creative Man file guide. If using the bevel jig without a file guide, clamp the blade securely to the bevel jig with 2 C-clamps rather than the included clamp, for a firmer grip. The Creative Man bevel jig is 150 mm (6”) wide with a slot in the center for the file guide (not included) and accepts up to 11 mm (0.4”) thick blades.
The Creative Man bevel jig features:
· solid stainless-steel construction
· non-magnetic, steel dust will not stick to it
· low-friction Nylon 1010 bottom liner for smooth operation
· stainless steel blade clamp for holding the tang to the jig
· Clamp the profiled blade to be ground blade in the File Guide (not included, this assumes you already own one)
· Insert the file guide in the slot in the bevel jig
· Taking care so the bolts stick in or out depending on what side of the grinder you are using. (On a Shopmaster 2 x 48" for instance, the bolts have to stick in towards you when using the left side of the belt as on this side there is no room for them sticking out into the grinder)
· Clamp the profiled blade to the bevel jig, using the included clamp, tighten the 2 bolts using the included Allen key. The bolts are to be on inside, towards you and placed on the tang side of the blade.
· Adjust the blade in the file guide if necessary; cutting edge sticking 5-6 mm (1/4”) above the top of the jig.
· Make sure the blade is the first point to touch the belt from tip to file guide.
· The blade tip has to be either stick out past the bevel jig on the side or above the jig if grinding a very short blade, in order to not grind into the bevel jig itself.
· Adjust the angle of the bevel jig by moving the two knurled thumb nuts until you have the required angle. This will require some trial and error based on your grinder setup and the thickness of the blade.
· Start with a quite aggressive angle to break the corner and go towards the scribed centre-line on the blade, or to the outer line of scribing two lines and grinding pre-heat treat
· Adjust the angle of the bevel jig to progressively bring the grind line towards the spine, this is often faster than starting with a flat angle and having to chase the bevels side to side until they match. If starting with a low grind (bevel jig leaning forward towards the belt) and getting this even, you can adjust the angle back to bring the grind lines slowly down the blade.
· After having ground one side of the blade, loosen the bolts of the bracket and turn the file guide around. Do not touch the file guide bolts, you want the blade in the exact same position within the file guide, just flipped around in the bevel jig.
· Adjust the angle back up to a more aggressive forward-leaning angle to again break the corner and when you are comfortable with getting even grind lines, start adjusting the angle back up to lower the grind lines towards the spine.
· Grab both handles firmly and start with light passes until you get familiar with the speed and motion for this belt/blade/grinder setupLong, slow even passes is the way to go. Don't stop and look halfway through a stroke but complete even, light strokes and then dip in water if necessary, and inspect how you are going
· Start 5 cm from the file guide and lightly go towards the file guide then back out to the tip, taking care to not twisting the bevel jig as you touch the file guide to the belt, to avoid the 2" divot from where the other corner of the belt digs into the blade
· Do not grind "off the tip" as in draw the entire blade off the belt. Rather when the tip of the blade is at the centre of the grinding belt, either pull the bevel jig straight towards you, or away in a semi-circle. (this is to avoid grinding too much off the tip) The small text:
The included clamp is for full-tang tang blades but will work with stick tang blades if not tightened too tightly. Usually this is not required but if wanting a stronger grip, use a small G-clamp instead.
1. The bolt for angle adjustment has two thumb nuts, unscrew one of these.
2. Pass the bolt through the slit in the square steel bar standing up between the black handles.
3. Add the thumb nut back on the bolt
4. Screw the bolt into the threaded angle bracket on the other half of the bevel jig
5. Adjust the thumb nuts by hand until the bolt is locked in place, leaving the bevel jig at about 90 degrees
6. Insert file guide with blade edge sticking ¼” above the top of the bevel jig, clamp firm but not too hard.
