Profile Sanding Wheels
Larick’s profiled sanding wheels are one of the most aggressive available. They are formed to match a profile and do not distort or ‘round them over’. There is a small amount of ‘cushioning’ built in to compensate for slight misalignment or movement of the profile due to inconsistencies in shaping or feeding. Normally, about 0003” to 0.005” is removed during sanding, which just removes a pencil mark. Abrasive cost is low, and averages about a penny per part sanded for kitchen cabinet doors. What enables this system to work is the ability of the abrasive to stretch. This stretch allows the sandpaper to conform to a profile as it is stretched onto a profiled wheel.
Raised panel wheels are normally made to use with a rub collar with the edge of the panel touching this collar. A consistent depth of cut from the outside edge is required when using a rub collar. Profiles similar to ‘L’ and ‘P’ work well. If the panel profile has a step or bead at the tip of the cutter, Larick will not be able to sand the entire profile but can normally sand from the step or bead to the outside edge.
Abrasive Installation Videos
- Limitations with this system:
- The smallest cove that can be sanded is 5 /32 inch.
- We cannot go into and out of a square inside corner. Therefore, we must skip any steps (as shown on profile ‘M’). Normally, sanding will start within 1 /16” of the corner and will sand the remainder of the profile.
- ‘Stepped’ profiles like ‘I’ require extra care in installing abrasive.
- Some profiles (‘N’ and ‘O’) utilize two strips of abrasive. On ‘N’, one strip does the cove, one does the round over, and the step skipped. For ‘O’, one strip does the wavy profile, and a second strip butts up to it to sand the lower flat, keeping the corner sharp.
- This abrasive will not come ‘straight out’ on the wheel, so we give a 15o relief angle on the top and bottom of profiles similar to ‘K’.
- The deepest that a profile can be in the sanding wheel is 3 /4”. A deeper profile can be sanded by tilting the wheel. Reasons to tilt are to minimize the depth of cut into the sanding wheel and to keep the abrasive as flat as possible on the wheel. This makes changing of the abrasive easier and gives prolonged sandpaper life.
Information required before manufacturing a sanding wheel:
- Bore size — 3 /4”, 1”, 11 /4”, and 40mm are standard.
- Tilt for edge wheels. Tell us if your sander spindle can tilt.
- Rub collar/bearing diameter for panel wheels.
- O.D. or minor diameter. If not specified, Larick’s edge wheels are about 8” O.D.
- Grit of abrasive desired. P100, P120, P150, and P180 are available.
- We need an unsanded part to use as a template and like to have some end grain.
- Shape all 4 sides of a small part and send to Larick. We will use part for a template and can test the wheel on the remainder.
