KR> DA dual action sander
This is a little more explanation for those who have never used a DA. A DA has a round pad that holds your sanding paper or buffing pad for polishing that spins in a circle for sanding or polishing. Along with the spinning in a circle, the shaft that carries the round pad is being moved side ways eccentrically, kinda like a left right and or up and down sanding motion along with the circular sanding motion of the round disk, there by the two way. An easy way to think of it is like using a hand held metal grinder which of course has a grinding disk that spins in a circle. When grinding a large flat surface typically one will move the grinder left and right and up and down to keep from grinding down into the metal surface. With a DA the left and right are automatic, but you do still have to move it from place to place to keep from buffing all of your paint off in one spot or grinding through your fiberglass in one spot. I have a Boshe sander that will just spin in a circle or can be switched to the dual motion at the same time. This tool has a switch to change from one to both operations. I have used mine mostly to buff my boat with wax. You do get extra vibration in your hands with the eccentric movement of the shaft that carries the spinning disk. Hope I didn't confuse anyone, but it is almost 2 am here. Guess maybe it is time to grind to a halt! Larry Howell DA is short for "dual action" sander. It is body shop lingo to describe the air powered sander that has been around a long time. Kevin Golden Harrisonville, MO In a message dated 12/6/2009 8:42:50 P.M.

It is easy to sand through the clear coat on sharp edges so I do the sharp edges and turns by hand with a foam sanding block. A DA sander is a round sander which is adjustable to different speeds. It makes sanding and finishing a much easier job. --- On Sun, 12/6/09, j...@aol.com wrote: From: j...@aol.com Subject: Re: KR> Paint :Imron To: kr...@mylist.net List-Post: krnet@list.krnet.org Date: Sunday, December 6, 2009, 4:43 PM In a message dated 12/4/2009 5:23:45 P.M.

KR> 3300 Jabiru to cool correctly
I have tried all kinds of lips of various sizes at the exit to no avail. I also have an in flight adjustible flap that hinges down to open and close the exit which forms a hige "lip" when in the full open position. It also has sides as we thought the air being displaced by the flap was spilling round the sides of the flan satisfying the low pressure at the mouth of the exit.. no luck. The air inlets were sized the same size as the four seater Jabiru aircraft which uses the same motor. What was not taken into considderation was the fact that the motorglider flies at a much lower airspeed than the Jabiru. My next experiment is to enlarge the inlets and see what difference that makes.

Porter Cable has a great DA sander that is Electric. Dry paper is the best. 400 to 800 grit for getting the old clear coat ready for the new clear. They work alot better when they are turned on and not in the box. lol happy sanding. Lee Van Dyke Mesa AZ flying Snakebite

DA is short for "dual action" sander. It is body shop lingo to describe the air powered sander that has been around a long time. I have never heard of using one with wet or dry paper, but I guess you could. I would think it would sling filthy water in your face, all over the shop, and inside your project. Watching out for the sharp edges is very good advice. Sanders eat through these areas very quickly. Sort of like when you cover a fabric wing and you avoid sanding on the ribs much to keep from eating through the fabric. Power sanding tools can do a lot of damage in a hurry if not watching what your doing. Be careful. Kevin Golden Harrisonville, MO In a message dated 12/6/2009 8:42:50 P.M.

Hi guys, Here are a few hundred people on this forum. Is it too much asked to write in a proper way and use punctuation? I'm not talking about people who's knowledge of the language (English / American) is low because it's their 3rd of 4th language, but WHAT does this mean: "and you do not have the power i have a kr2s i know what motor gives the most grunt" What IS KR-related, is my search for a plan for an engine mount for a Soob EA81 TO BE ATTACHED TO A KR2.

There are several KRs with Jabirus installed, and many of them have or had cooling issues, although KRs are fast enough that cooling isn't usually as large an issue as on a slower plane. Apparently those considering using a Jabiru should be aware that special attention should be paid to cooling issues. At the risk of sounding like I'm pushing the Corvair, Corvairs have no such issues, and VW's don't seem to have a problem with cooling either.
