Just a quick question on deburring. Below is a pic of my new timing chain cam sprocket. You can clearly see left over burs on the outer edge of 2 cam bolt holes. I'm kinda mad that quality control didn't catch this & clean it up before they boxed it, but maybe I'm just **** about these things! Anyways, what would be the safest method of cleaning this up. I was going to use a triangle file to scrap it but I want to check with other peoples opinions also. Thanks!

Here's a pic of the other side too.

 

There are "deburring tools" available, look like a crooked file...would work easily in the first pic, 2nd pic might be difficult to keep frmo whacking into the lip on the sprocket....so I'd opt for a round or moon fine file...not one with a edge (flat/square/triangle, etc) to keep from gouging.

I hate stuff like that too...a machined part that needs finishing work on it. But I would remove the excess...to ensure even torque on all the fasteners.

 

Hey thanks for the suggestions 8Mike9! Here's a pic of the triangle file I was gonna use. I might go with your suggestion of a round fine file for the other side though.

 

i always use a drill bit that is larger than the hole

 

Cool. I never thought of that one. Thanks!

 

You could also use a rotary deburring bit, either a rosebud or spherical. They're about $7. If you're only doing a few holes, a larger drill will be fine, so long as you control the depth.

 

bigger drill or countersink works well. was that part made overseas? I see alot of oversea's parts that they take no time to deburr. Not deburring realy sucks when you cut your self on the burrs like i did on a recent wheel barrel while assembiling.

 

I got it straight from Comp Cams. The box says "American Made".....but when I looked on the link chain itself guess what I found....."Japan"! I guess they outsource sometimes huh lol!

Thanks for everyone's suggestions. It's a minor thing but many of you jumped right on it to give me some help. These boards rock

 

when using the bit to deburr, do it by hand not with a drill

 

Kinda figured Thanks!
