I notice there are different thickness in the LC flat pad. Some 1.25 and some 3/4 inch. Any differences between them? Also which is the preferred thickness for rotary and DA..
The foam is the same. The thicker ones have the constant pressure foam backing on them which gives the pad a nicer feel to it. I prefer the thicker ones on either machine.
Foam pad thickness 1.25- inch pad thickness was set as an industry standard because it prevented residues and provided insulation from friction heat from reaching the backing plate, either of which could compromise the Velcro® delaminating backing material. There is a safety margin between the edge of the baking material and the foam with this ‘standard’ foam pad. This foam density provides a protective cushion allowing foam compression to maintain constant surface pressure and it also lessens machine vibration. Like all things related to tools, pad thickness comes down to personal preference. I should also state that a 7/8th- inch thickness foam has it backing material flush with the edge of the pad, while the 1.25-inch has a safety margin between the edge of the baking material and the foam, there is also has a cost saving on the 7/8 – inch foam
I had seen a picture of the pad manufacturing process which is simple. They just take sheets of foam and laser/hot wire cut them. There is a lot of scrap in the process so hence the desire to reduce pad thickness. That is, you are paying for the pad plus what gets disposed (recycled?).
Remembered reading somewhere (neighboring forum) stating not all LC pads are the same, some where tailored to the requirements of the retailers/resellers. Hmm... :shead:
