Cylinder recondition how-to help
« on: May 15, 2012, 06:53:54 pm »
Can someone post or point me in the direction of using muriatic acid to recondition a cylinder?
The more info the better.
I have a Stihl HS 45 hedge trimmer that needs a little freshening up.

Thanks, Glenn

All i do is add the acid to the aluminum transfer on the cylinder with a q-tip. sand that area and repeat several times untill all the transfer is gone.

Menards carries it as well.  I like to heat the cylinder as well.  The acid reacts faster warm.   Make sure your work area is well ventilated, the fumes are very strong.

I'm pretty sure someone put a video of the process on youtube.
I saw it on AS, it could have been from one of the other hosting sites.

FWIW you can use easy off oven cleaner and get about the same results . A word of caution do not get impatient and use a flap wheel on a cylinder .You'll grind right through the plating faster than you can say Jack  Robinson.Been there ,done that .

I might also add that 3M abrasives like the green pads are less agressive than sandpapers .Unless you really lay the elbow grease to them they will only take out the tramp aluminum .Wear some kind of rubber gloves weather you use oven cleaner or muratic acid and have plenty of ventilation else the fumes will get you .Not good . :o

I use a flap wheel everyday and have never even marked the chrome but like I say , I take a new wheel and grind steel with it for a minute or 2  but I'm also thinking that maybe we are not taking the same thing here on the flap wheel, Where I buy them that is what they call them , I also use easy off with a bit of heat before hand on the jug, works very well and fast , On most jugs I clean up I'm 5 minutes and I'm done

A flap wheel is a flap wheel . I can't remember exactly what grit it was but I can assure it will cut right through the hard nickle alloy Stihl plating .

They make them in different grits ,different hardness and in fact in 3M greenies if you want .My problem was I just got impatient and got a little heavy handed with it .---soo the result was an 036 cylinder and piston on an 034 bottom end which worked up  better any way .Live and learn they say . :)

I also think there is quite a difference in the grades of flaps wheel besides the grit number , I know the wheels from fastenal and no where near as good as the wheels from Brafsco , huge difference , same grit and size
