GUINEVERE® is a complete, miniature sanding system that uses small, flexible, inflatable sanders. The 2006 National Hardware Show showcased this patented system, developed in Sweden, for fine sanding and finish work.
It is the most revolutionary sanding system to come out in years.
Guinevere uses a selection of inflatable rubber sanders, flat and round, with both sanding and polishing sleeves, from coarse to extra fine, fitted either to a flexible shaft or the quiet 1/2 HP (300 watt) motor. The inflatable sanders are ruggedly built from Swedish steel and heavy rubber.
This system easily eliminates your laborious hand sanding process, saving you countless hours of sanding. You will actually enjoy this sanding experience. You can create a smooth, velvet finish that is truly unique. An extensive line of accessories, sleeves and pneumatic sanders are available to address all your finishing needs.
This revolutionary sanding system is the perfect follow-up to MERLIN® – the miniature chainsaw cutter that cuts in any direction. The GUINEVERE® sanding system completes the unique miniature tool line available from King Arthur’s Tools®, providing tools to bring your vision to reality.
Frequently Asked Questions
Q: What makes Guinevere different?
A: It is compact, versatile, original in design, flexible and easy to use. Many pneumatic sanders have large drums and hard edges, with a valve protruding from the bottom and fitted with a hefty drive shaft. Good bye! Guinevere has eliminated these problems by forming tire rubber into both a drum and dome shaped sander while placing the air inlet valve unobtrusively through the drive shaft. This makes Guinevere sanders far superior to others on the market, especially the rigid styles. It is also available in three combinations to suit different market needs.
Q: How do you inflate the sanders and what is the result?
A: With just a few strokes you can pump the drum sander up making it hard and flat, using it like you would a rigid drum sander. The best pressure is to only pump the sanders once or twice with a small thrust. If the sanders are only partially inflated they are very compliant. This lets you sand inside and outside curved, contoured and convex surfaces with ease. As you push the drum down to the work it folds over or into the surface. The result is a beautifully smooth and velvet finish on all surfaces. For specific details refer How To Inflate Guinevere’s sanders, Loading Models 11341 Drum Sander and 11351 Round Sander.
Q: Is dust a problem?
A: Dust is a potential issue with any hand held power tool. The dust particles and residue are very fine but confined to the immediate work area. Wearing a dust mask and having a dust collection system is highly recommended.
Q: Can I use an air compressor to inflate the drums?
A: We don’t recommend it for the following reasons:
a. The drums require very little air, so it’s very easy to over-inflate them with a compressor. If over-inflated too much, a bubble of rubber will force its way out from under the sleeve. Once this occurs, a permanent weak spot has been formed on the bulb.
b. The compressed air system must be able to deliver totally dry air, otherwise moisture will cause rust on the internal steel parts, and will interfere with the airtight seal of the interior valve.
It is very difficult to "tune" the bulb to the right softness while inflating. The best way to inflate the sanders is with King Arthur’s Tools Guinevere small 2 way hand pump, which allows you to feel the softness of the bulb while you are pumping, giving you the ideal drum softness for the grit being used. A regular bicycle pump would be a preferred second choice, but usually requires two hands on the pump. The best pressure is as soft as possible while still keeping the sleeve from moving on the drum.
Q: Can I sand materials other than wood with these drums?
A: Yes. The sanding sleeves we supply are metal quality and very sharp. When sanding metal, or other hard materials like bone, horn or plastic, be aware that you are sanding with a soft rubber bulb under the sleeve. Avoid holding the drum in the same spot and allowing heat to build up possibly burning through the abrasive cloth. Watch for sharp burrs or projections.
Q: Air seems to be coming back out the shaft after I inflate the drum, and my sleeve goes loose on me. What is happening?
A: Occasionally, sawdust or other dirt can be pumped into the shaft when inflating. This grit can get under the valve on the inner shaft, and create a tiny space where air can escape back out the way it came. If this happens, simply remove the bulb, and roll back the inner valve, and clean out any grit. Take care not to cut the inner valve with your fingernail, pen, pencil etc. when doing this. It’s good to form the habit of always cleaning off the shaft end before inflating.
Q: I put the sleeve on, inflated the drum, and now it seems "bumpy" when I sand. What’s up?
A: Check the sleeve, and see if the lap joint of the sleeve is straight to the centerline of the sander. If not, it can "catch" on some types of material, causing the bump on each revolution. As you look at the drum with the shaft pointing downwards, the high side of the lap should be on your right for clockwise operation.
