How to Diagnose a Bad Power Cord or Switch
This article outlines the basics of power tool and appliance electrical diagnosis. You can use a multimeter to test tool and appliance cords and switches, the two parts usually responsible for electri...
The Ridgid sander is the best I have and the disc assembly still looks new, however it will not hold any sandpaper. I use because of a buildup of something on it from previous paper. How can I clean this so it will take paper again and not have to spend 40 dollars?
Hook & Loop sanding pads offer many benefits to the woodworker. They offer the ability to change sanding grits quickly. The user may remove and then reattach a sandpaper disc allowing for maximum use and reducing the cost of sandpaper.
The Hook & Loop sandpaper system consists of a sanding pad with fine plastic hooks, which is attached to the sander, and sandpaper discs, which have a looped fabric backing. The loops on the fabric backing are held by the hooks on the sanding pad.
Hook & Loop sanding pads will last through several hundred sandpaper discs with proper use. The most common cause of a Hook & Loop pad to wear out prematurely is excessive pressure being applied to the sanding pad. Only enough pressure should be applied to the sander to keep it on the workpiece and to guide the sander in the desired sanding pattern. Excessive pressure creates heat build up in the sanding pad which will quickly damage or even melt the tiny plastic hooks. Once the hooks are damaged they will no longer hold the fabric backing on the sandpaper effectively and the pad will need to be replaced. When excessive pressure is applied it slows or even stops the random action of the sander causing a large increase in swirl marks left on the workpiece.
Best results and fastest sanding will be achieved by using light sanding pressure and a proper selection of sandpaper grits. Start with the coarsest grit needed to quickly remove any rough wood surfaces or uneven glue joints. Once the surface has been smoothed and leveled you can move through the sanding grits to the desired finish. Never skip more than one sanding grit at a time. Skipping grits requires additional time and effort to remove the scratches left by the previous grit. The finest grit needed depends on the type of finish the project will receive. If a film finish, such as polyurethane or lacquer is to be used then 180 or 220 grit will be sufficient. Film finishes can have problems adhering to surfaces sanded finer than 220 grit. If the project is to receive an oil finish then a 400 or even 600 grit finish may be desired.

I think that this sander could be ranked a 5 if the hook & loop pad was more robust . Furthermore if one could purchase the sticky hook & loop pad by itself it would be a lot more economical. Now I am faced with making one myself (it ain't rocket science ) and Ridgid will lose a sale on a 32.00 pad. If they had made spare sticky pads I would probably have bought more than one at a lot less cost.
quite possibly the best electric R.O. I have ever used, but I wish the hooks for the hook and loop were more robust. They occasionally let go, and then... I think it has something to do with heat build up. If the hooks were made slightly larger, and of a material that was less likely to deform when hot, then the problem would go away. As it is, in my experience, the pads will get smooth, and even occasionally glaze if you are running through a large sanding operation. one or two sheets a day and the pad lasts a year, 40 sheets in a day and the pad needs replacing.
Very strong sander and hooks up to vacuum easily but I must downgrade my rating due to the major part that wears out is very expensive- The sanding pad. It cost 4x more than other sanders (that are just as good or better) replacement pads. These pads all wear out and need replacing after about 100 hours of use.
