Im looking for advice from someone who builds their own engines. I have a very important qestion, not about fitment of side seals but how everyone does the tips of each side seal when it is ready to be finished off. After the side seal has been trimmed do you make sure to completely smooth out the squared corners where u sanded or grinded the side seal to fit the side seal tightly fits against the corner seal. I would say yes to this because that would weed out the possibility of a corner seal getting stuck or possible binding of the side seal it self. I would assume this may be the right way of doing things maybe? Or do you want the side seal to still maintain its squared ends so it looks a perfect diagonal line at the tips. Again im just assuming here that since the corner seal itself is a cylindrical shape wouldnt you want the side seal ends to have smooth cylindrical shape as well to prevent snagging? Please fill me in on the secret guys. Need some help here

 

 

hmm i sure would have expected this guy to polish the ends of the side seals when they were done or make sure to sand out any corners or rough edges while still keep the integrity of the side seal diagonal angle.

 

Now im just wondering if i was wrong all along. I guess it makes since that a completely flat surface angle to the corner seal provides the best tight fit for compression purposes am I right?

 

Please delete mods, wrong thread, thanks.

 

machining side seals to the spherical curve of corner seals at less than 10% of the diameter mating surface makes the thought of honing side seals absolutely dreadful
what kind of tools are you working with?! I use a knife sharpening whetstone...

 

I use 1500 grit flat whetstone when fitting my side seals.

I do a swipe on the backside/sharp side to remove the wire burr that can build up after grinding in the angle and then clean the end of the sideseal with an oiled cloth before test fitting.

I havent noticed any burr building up on the sharp corners that doesnt come off with the backside whetstone swipe.
