I was waiting for these two to come in. my double cut bent at 32,000rpms! I run my Makita at 7000rpms, which is the lowest setting. Vibrations get crazy at more speeds with these 6 inch shanks.

I straighten mine! It is tough though to work with that length. I wonder about a small handpiece that could get farther in there?
BTW, I use floor paste wax as a lubricant. What do you use?

I usually just chop off an inch to shorten the shanks. I use Murrays Black Beeswax.


Give me a few hours. Brb!

I see. I use a bluepoint die grinder harder for me to control but I set my middle finger under the trigger and hit it with my pointer.

One day I'll trim a wood block trigger stopper to get the rpm I like using when porting aluminum. Keep up the good work. Have any pics of v25b ports? mostly would like to see how you treat the exhaust ports.

I treat them the same way S20, W25, D25 since they are the same casting shape. Not much bad spots really, just smooth out the turns. I don't have much comparison pictures of those vs the B25.


My arm tires out quickly since i don't port often.... Gotta get back in shape. Lol

these will flow easy 260cfm+ as they are in this picture (baby D size). They are getting full DD enlargement when done.

What's the hole/pit on the ports on the left? Is that gone too far or a casting mark or?

I know what you're saying about the fatigued hand! You ever try a final finish with emery by hand? It's so pretty..

aluminum would destroy my double cut bits just like iron would destroy my single cuts.

I run mine threw the wire wheel after and they are good as new. But if you let the dermal do the work at low rpm it tends to cake up less. For some reason my 6" bit didn't last :-( but that's good because I only use it around the valve guides and to smooth tight angles.

This is Polish after 1000grit wet sand. I won't be doing that anymore for the exhaust.


Gotta keep the bit lubed. You'll notice when it starts to clog up. I stop porting to clean the bit with another bit by hand running it in the grove with its teeth.

You need to post an idiots guide to porting step by step guide. I've done turbo exhaust housings, ex manifolds and some minor gasket matching/smoothing work on a buddies spare cylinder head but I have no idea how much or where I should cleanup mine. I was informed after I built it that I should've ported it to get the most outta my big cams. Now its coming apart again so its time. Otherwise I guess I poke through all 40 pages of this till I'm not scared.
