We recently received the Flex LP 1503 VR sander. We ordered one from
McMaster-Carr @ $735.00. Then we shopped it on the web @ $435.00 and
marched the McMaster one right back to them. We noticed the McMaster
one came with a couple of rollers and an orange screw on handle. We're
getting bad service from the company that sold us the cheaper version
and are trying to figure out how to buy the accessories and perhaps a
carbon brush set. Any ideas?
Porter Cable repair centers carry parts and accesories for FLEX tools.
Check their website for a local repair center.
What is a "carbon" brush set?
The wheels I know they have for them are Scotchbrite, flapper, sand
drum, and wire wheel.
I've got a 28 year old Makita profession quality drill that's had the crap
beaten out of it and it's still running on the same brushes. Local service
company said the main reason for premature brush wear is running power tools
on light duty extension cords.
That make sense. "light duty" means small ex:18g 50ft, and that implies
more voltage drop because of the resistance of the wire and thus
more current needed to deliver the same power to the motor.
since heat is function of the resistance of the winding
and the square of the current I would guess that light duty cords would
lead to motor failure due to motor winding insulation breaking down due
Is it also that the brushes are behaving like the stick in an arc welder
and at the higher current are being consumed.
Maybe the brushes are not moving in toward the armature as they wear and
the spark gap is increasing and that is causing the wear.
Could it be that the brushes are cheap and too soft for the job.
A lot of good name companies have been co-oped by lawyers and MBA types
and have started to put their good name on cheap tools to make more
money this quarter.
I have a 30 year old B&D drill that is still going strong after my newer
B&D's have died.
Maybe the armature is too rough and wearing them out.
Good luck, I know lesss than it sounds:-)
I just felt like jumping in.
