fed one hell of a hot supper on the first day

fed one hell of a hot supper on the first day
I bought this cause my grinder is a battery milwaukee that lasts about 10 mins of low pressure grinding and my old corded one got jacked out of my garage.I knew full well what the project was when I ordered it. I got a piece of a scrapped machine at work and wanted to use it for ballast in my 4x4 in winter without giving up cargo space with sand bags.I am a truck mechanic and have been for many years. I have put many quality grinders in their final resting place. Most of them you could tell on day one what to expect.This one will be with me at home for the rest of my years. I fed this thing a hot supper for 8 hrs strait upon receipt. amazon got it here 2 days before promised which was exactly when I needed it. I was finishing blowing snow when the mail man brought it and went right to work. I used up 8 cut wheels 3 gemini cut-n-grind (which are awesome) and 6 flap disks.First the bad. The guard is way too big. I am sure it is for consumables that have the built in nut because they are much taller. I cut and sanded it to be correct for the type I use. Then the spindle is too long. with a wheel on it sticks out 5/16 past the nut. so I took er to the belt grinder and with the motor running sanded it flush to the nut...took the nut off and feathered a little chamfer on it. Something inside was chattering when I started. I took the cover/spindle off of the gearbox and smeared the high quality moly grease over the ring gear, which was dry. the sound continued for about 20 mins then went away and it ran as smooth as any I have ever used. I think it may have been the brushes on the commutator getting acquainted.The good. More power than you need. The consumables can only handle so much. It is light weight/power balanced and smooth, after a break in period. Running a grinder is never "fun" so having one that can make the least work of it is important.5 stars is not enough. There is sooo much junk out there now. this is not that. pro grade tool ready to work. 1 star assembled in USA. this is important to me as we make great stuff, I hope they expand on it. I bled red for many years but the future may hold primarily yellow for this reason alone. 1 star for power. 1 for staying cool. 1 for feels good in the hand. 1 star for fast and easy disk change. 1 star forthe cord, very flexible and did not get hot. 1 star for packaging, not excessive and went in my wood burner not the dump. 1 star cause yellow tools are hard to lose in a mess.lost a star as it did not come with the spanner for the nut, surely a packaging mishap. it did come with a 3/8 allen wrench that I have no idea why. still way over 5. I did have to remove a few wheels with the edge of a table yesterday. You just hold the lock, which is perfect on this tool, tap the wheel on the edge of the bench in the correct direction and it comes right off....you often break the wheel doing this but it is usually not one worth saving if you do.

Sin duda la mejor amoladora que he tenido en mis manos... Buen tamaño, manejo rápido para manipular la guarda, cambio rápido de los discos con la llave Allen, gran potencia de trabajo con menor esfuerzo físico...Es la primera que tengo con estuche o caja para su transporte... La recomiendo ampliamente y al vendedor también... Llego rápido aun con los días festivos, la pedí el 25 de diciembre y me llegó el 2 de enero.
