I recently got a braid nailer/staple gun,Tradesman,magnesium series,model 8530.Taiwanese piece of crap. Its actually a nice lil air tool for the cost,think it was about 100 bux.Got it back in sept/october,and used it 3 times.1st time i used it for nailed down oak floor,just the last row by the wall.Used it again to make a cabinet fer the garage.And was trying to use it today to put up some moulding and the push pin kept hanging up. Called customer service and the housing fer the piston is ALL plastic,The cylinder ring(which is also plastic)has a lil lip on it that sits in the top of the gun.Thhis keeps it from moving,well that lil lip broke off and is the reason the push pin hangs up. I was told the warranty does not cover moving parts!!!???? Besides the housing of this gun EVERYTHING is a moving part! LOL And its all plastic!!!! Where are all the tools i remember my grandfather useing,heavy powerful tools with metal parts?All his tools work fine and hes had them for over thirty years!Ya go out and buy a newe tool nowadays and its mostly all crap and breaks in a matter of months. Thats it fer me,no more new tools,I'm getting all my tools at yard sales and flea markets!At least i know if i take care of them they will last a lifetime!
