Windshield Repair Forum

I have been looking for a disc sander that turns at around 1200 rpm for my scratch business. I currently use the Makita GV5000 unit that turns at 4500rpm and have been told by several people to slow it down. I tried to find a variable speed switch but Makita does not make one. I noticed that the one that glass mechanix sells with there kit shows 1200rpm. Is that a misprint and if not is that a Jepson drill or what is it? Thanks Gary

Rather than buy a new machine would it not be possible to put a variable switch in the power supply lead I have done this before and it works. you should be able to get one for about $10 somewhere.

Hi,

The machine they offer at GM is a Jepson with variable speed, the max speed is approxm. 4500 RPM. You need to slow down that indeed, but that machine will do the job in a perfevt manner for you.

Makita 9227 Buffer. 600rpm to 3000rpm. I find it easy to use and works great for this aplication. http://www.makita.com/menu.php?pg=product_det&tag=9227C

The above mentioned buffer is great(have one myself) but I have moved onto the PW5001C( http://www.makita.com/menu.php?pg=produ ... ag=PW5001C ) this is also variable speed, but is also centre water feed, which will open doors for you relative to deep scratch removal. With this machine anda trip to your local industrial supplier for a few backing pads, 3M trizac discs and you have the begining of a porc inspired scratch removal system for a lot less money.

Enjoy

COOL just checked it out. Just wondering how the water is feed? Is it continous? Push a button? etc... Do you just hook it up to a hose (heavy ) or do you some other source? This would be a nice new toy!

I use a small(3/8id 10' long ) hose that then connects to a regular garden hose. When a garden hose is not close I use a pressure sprayer(like we used to use when insectsides and pesticides poluted our enviroment) to connect to the grinder. With the polishing powder and felt discs use use little water, with abrasive discs more water is required to lubricate the cutting surface.

Merci
