What type of sandpaper do you use? Aluminum oxide is the most popular because it abrades well and is harder to clog. The oxide surface on aluminum builds up faster than you would believe. I used to do a lot of tool design for a company that made composite parts for aircraft (they changed hands and moved to China many years ago). The parts would have to be cut with a diamond router bit held perpendicular (normal) to the contour of the part. They would buy really good router heads, mount them in an aluminum "sled" that was then driven down a sheet-steel "track." They were constantly rebuilding the "tracks" because the "sleds" would wear them away! After several years of this, I finally convinced them to bond a UHMW Polyethylene spacer to the aluminum "sled". The "tracks" never did wear out! |

I don't get it. I have a paypal account, and it's linked to my ebay account... I'm gonna try this: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=130359923593&ssPageName=STRK:MEWAX:IT A tad more expensive, but it's dispatched from the UK. --- End quote --- Did you manage to get one ? If you cant get one from ebay try this http://www.dealextreme.com/details.dx/sku.41842 postage is free but can take a while as they come from hong kong and if you keep the total under 18 quid there is no import duty to pay current exchange rate makes this roughly £9.42 Jason |
