How I grind for BURR

[@clarkmcmahan1595]

Great work I like the use of the scroll after to give your final taexture...

[@dominicmizzi4279]

Nice! I’ve been porting for 30 years and I do burr finish just like you. It truly is an art!

[@BrentAllen99]

Thanks for sharing this kind of stuff! I haven't ported a head yet but thanks to helpful videos like this I have a better understanding of how it's done. Thanks again 🤘

Thats a heavy cut burr. I use a fine tooth Hi Helix burr. I love the finish it puts down. The problem is finding someone who can make the right.

Chad Speier, thanks for posting. I hope to get to see more!

Master of the Craft!

[@nickkiofetzis5667]

awsome work chad, i am very impressed with your port all the time

[@dondotterer24]

In what cases do you use a Burr finish? And when not to? And are there some places do you want more of a smooth or polished finish? Thanks for the video.

[@drcolster]

When cutter is a little bent, or die grinder is'nt running true.... it gives rougher finish...from my experience in Porting...

Is this legal for Stock? LOL! Good luck in 2024. Hope to see you in the lanes.

Burr length works well - lets it dance a bit.

[@SpeierRacingHeads]

I don't want it to "bounce"

[@KS-dg5zh]

That bit really throws the chips.do you do the whole port around the valve guide like that?

[@SpeierRacingHeads]

yes

[@chevyrc3623]

That's cool

[@Yedardy]

So I can get a better understanding what does a burr finish do compared to let’s say a smoother finish?

[@SpeierRacingHeads]

creating more boundary layer and help keeping the fuel off the surface.

[@petemcpeterson6205]

How do you control such a long tool ? ( what she said) lol

[@SpeierRacingHeads]

You defiantly don't want it to bounce. Kill your hands and not a uniform pattern.

[@circlejerk6861]

Is this finish fuel specific or across the board?

[@SpeierRacingHeads]

I have never had it hurt a port

[@circlejerk6861]

Good answer
