Thank you, I'm not a porting God but I do my best.



On the last motor the kiddys hated I tried to do some different stuff see what happened. And actually it did quite well. I have a chance to change the ports up again and I will and try something different similar to this one and see the difference.

Do you use the drill press for anything else other than the bridge? Looks clean!

I think that the Bridgeport is a good choice for a Bridge port!!



It looks really clean.



Nice work.

That is not a drill press it is a Mill.



Racerguy180. You win the prize you are the first person to finally notice that.

I would have cut at an angle to help flow. You can still back cut under the o-ring groove a little.



I wish I had a BP mill.
