Scotchbrite after sanding?

I read with interest most discussions on this site, and I learn a lot. For various reasons (including a new house) I haven't had much time to build rods lately, but I am hoping to get back to it this spring. A couple weeks ago Ralph O'Quinn posted a very interesting note on Scotchbrite (7448 I think) and the improved epoxy bonding to the blank using this instead of sanding, cleaning with alcohol or any other method. I have a couple blanks and reel-seats which have already been sanded as was previously recommended, but not epoxied together yet. The sanding can't be undone, but I was thinking that by using Scotchbrite I might still obtain the other positive effects which Ralph mentioned. To answer my own question, I guess it wouldn't hurt, but any comments are greatly appreciated. Sigurd Stefansson Bergen, Norway Re: Scotchbrite after sanding?

Well you do not want to sand a graphite rod do to the fact sanding well cut in to the graphite fibers and cause the rod to fail under pressure. scuffing a rod with a gray scotch brite pad only deglazes the rod Bob Re: Scotchbrite after sanding?

Thanks, Bob, Perhaps 'sanding' was not quite the right word, rather to create a 'matte' surface on the blank (these are coated blanks and I'm not sanding anywhere deep enough to touch the graphite). Scuffing the blank lightly with Scotchbrite would still be possible. Sigurd Re: Scotchbrite after sanding?

Bob,I am from a different country and have difficulty finding Scotchbrite 7448. Will other scouring pads do the job as well? Thanks HSelesa Re: Scotchbrite after sanding?

3M's pad seem to get the nod for providing the "charging" effect. Perhaps Ralph knows of another pad that gives the same benefit, I do not. Since you have already abraded your surface the only thing you may gain with the Scotchbrite is this particle charging effect. Go ahead - it won't hurt anything. The only thing you need to look out for is "over preparing" the surface. By that I mean disrupting the surface with scratches and gouges that are too deep and too many. You can overdo this, although it does not sound as if you did. So put your mind at ease. Anything you do with the Scotchbrite pad is not going to hurt your bond. And I would think that the bond you get even with the surface you have now will be sufficient for what your rod is likely to encounter. ........... Re: Scotchbrite after sanding?

Hi Sigurd We often want to bond a surface that is quite rough. The best bonding surface is one that is smoooooooth. In this event it is necessary to smooth out the surface by sanding -fileing, or whatever it takes to level the playing field. Just be careful not do any gouging. After our surface is properly smoothed, then an application of Scotchbrite is in order. An example is rough-out , unsanded blanks. The rough texture is not the best bonding medium--smooth it out somewhat with sandpaper or a file, then judiciously prepare with the Scotchbrite. Graphite reel seats usually contain a layer of crud --- run a solvent saturated rag through the seat to remove most of the black crud, then a rolled up piece of sandpaper to level things out somewhat followed with a rub down with Scotchbrite -- this latter operation being quite difficult to do. Notch the end of a wooden dowl, cut a couple square inches of scotchbrite, insert it into the dowl and spin it into the interior of the seat using your power wrapper. Hope this helps Ralph Sorry, only registered users may post in this forum.
