Belt Loading Problems -
A very easy and helpful solution to belt loading is a "rubber
cleaning stick" (ask our sales rep for information). This rubber-based stick, generally 8" in length and
2" square, is held against the loaded belt as it is running. The
rubber pulls out trapped sanding residue impacted between the
abrasive grains, thus increasing the belt life. Note: This is not recommended for
wide belt sanders.

Hand Sanding Contoured
Wood Shapes - This age-old problem can be easily remedied with KLINGSPOR's Mac Mop. This wheel consists of hundreds of small
abrasive strips bonded to a strong epoxy core. Typical applications
include the sanding of turned wood parts, scuff sanding of sealer
coats, satin finishing of metal parts, mold sanding and sanding of virtually any
profile. Mac Mops are available in two sizes: 10" x 2" and 10" x 4"
and in grits ranging from 80 to 180. They are best used on a motor
with at least a 3/4" diameter spindle and operate at between 1100 rpm
and 3000 rpm. |

Shaping a Flapwheel -
There are several ways to efficiently shape or profile a KLINGSPOR flapwheel. One method is to run the flapwheel backwards and hold a
silicon carbide dressing stick against the flapwheel. These are the
same type of dressing sticks used to dress a grinding wheel. Another method is to glue some 40 or 50 grit sandpaper to the profile of the
workpiece, again running the flapwheel in reverse. Then hold the
abrasive against the turning flapwheel creating the profile.

Random Orbit Sanding -
When using a pneumatic random orbital sander, it is very important
that the air pressure, while the tool is under load, be maintained at
90 p.s.i. Maximum air hose length should be kept to 20 feet from the
main feed line. 1/4" coupling and air lines will restrict the amount of air flow needed to run the tool at optimum levels. Most tools
require an air volume of 15 to 18 cubic feet per minute (cfm). Ideal
air line size is 1/2" line with 3/8" couplings. |

Achieving a #4 Finish -
This is probably the most common finish in stainless steel
fabrication. This finish can be achieved by using a 100 grit aluminum
oxide belt followed by a medium grade non-woven material. |

Tape or "Butt" Joints
on Abrasive Belts - A tape joint, also referred to as a
bi-directional joint, can help increase the life of an abrasive belt.
As a belt becomes loaded from sanding residue, the belt can be
removed and reversed so it is running in the opposite direction. This
will help clean the belt of the residue and expose new abrasive
grains, thus increasing the belt life and ensuring consistency of
finish. |
