Ah the broken blades scenario of the food processor? It’s not broken it just need fixing better than it was before. How you ask?
Do away with the cra*y plastic hood, which the blades are attached to, underneath is the metal drive spindle which tends to be oval or hexagon shaped.
Get a 12 inch piece of stainless steel ½ X ¼ inch drill a small hole at 6 inches 5 mm max.
Measure the thickness of the central column of the jug that the hood fits over. Allow 12 mm clearance either side of the column, scribe a line and bend downward in a vice from the line. You now have two prongs, place the prongs in the jug with the drilled hole directly over the centre of the spindle.
Measure the distance from one of the prongs to the inside edge of the jug and the depth of the central column.
If the central column is say 4 inches deep, mark a scribed line at 3 ½ inches on each prong, then bend outwards in the vice, this gives you a pair of wings at the bottom of the prongs.
The central hole of the pronged wings now needs to be worked on with a small file (equally on both side of the hole) so it fits neatly to the central spindle.
When done test the hole fit, and if the wings are to wide for the jug, they’ll need to be cut down equally either side with a 12mm clearance from the side of the jug.
All you need now is to put an edge on the forward dive side of the wings with a *******file or a little grinder.
The key to making these cutters is to keep everything equally on both sides so its not unbalanced.
You can now wiz away till your hearts content with pellets, boillies, hard bread.
Mine I made 5 years ago on an old cheapo food processor that’s still going strong and has probably made several tons of stuff.
As Binka says you do need earplugs for pellets as they don’t half rattle when you set it going.
