Chamfer

[ski4]

Damn, after putting the whole motor together , i figured i would find out if the guy that charged me $60 a hole to do my boring chamfered it. I did not even really give it a 2nd thought for what i was paying. i only recall thinking at one point " damn these are sharp" but was too pissed about my terrible decking job and non rotating crank

turns out he did not arghhhhhhhhhhhhhhhhhhhhh
any how, i have been told, and am reading to use a round file or dremel. anything wrong with a flat file? just curious why round is preferred

and i only have flat files laying around

I wouldn't use a dremel...

 

[djkorn1]

Thats like cracking an egg with an anvil..:bigeyes:

 

[ski4]

that is how i crack em though, makes it so you don't feel the shells when you eat em

I did mine with a dremel - very very carefully, of course. A flat file would work just fine.

 

[ski4]

i couldn't think of a reason a flat file would not, just curious
thanks matt

 

[MADMAT]

Do I need to do this too? Same guy did mine, right?

The exhaust port is curved a flat file is not going to work very well.

Round file or Dremel. I always use a Dremel, just be careful. I use a 3/8" cylinder stone I believe.

matt if it is the shop by dj's
yes you should do yours too i bet.

good call about the exhaust port makes sense, i best go get a round file then
ergh

 

[Matt_E]

As long as the flat file is thin enough, it should still work.

It's been my experience with a couple of shops that they do not chamfer ports by default.

Thats true, most shops don't automaticly chamfer the ports.
I tend to do it for my customers as a curtisy because I know the intended use.

If you want to do it yourself easily, get a small round file & finish with some emory paper
