Question I should Know the Answer To

[D.A. Davis]

For you guys that grind your own tapers, is the rate of taper ground on one side only?  Or, is the material ground on both sides equally to achieve the desired rate of taper?

[Trux Turning]

I end up flipping mine as I reduce them so I guess that means both sides

[Jorgy]

I flip mine,mostly to take the bandsaw marks out.

[Roy from Pa]

This is something I have never even thought about, but it makes sense... Gonna try it on my next tri lam...

[bigbob2]

Yup flip mine also.

[kennym]

I saw them at the proper taper rate with a 2" wide sled up against the fence, then grind both sides .

Then you don't have to grind as much as from a parallel, and the grain matches better too.

I start .040 over desired thickness...

[jsweka]

Why would it matter other than to get out any imperfections caused by a sander & sled that aren't perfectly parallel to one another? -Maybe just to sand both sides for glue adhesion, but I can't think of any other reason.  The resulting taper is still the same.

After re reading your ? , what John said!  

[Roy from Pa]

Johnny Boy, The taper is the same on one side but the other side is flat, so the bow could shoot high or low depending on the angle of the hyper extended fibula..

[kennym]

Sheeesh! Thet's perty technigal fer a non-glass feller Roy!

You try that sand yer conveyor trick yet?  :D

[mjwhitby]

You wouldn't happen to be the D.A.Davis from ASU would ya?

Ah ha...I see the light now, Roy.
I guess that's why I'm a biologist and not an engineer    

[Roy from Pa]

Yup Kenny got the belt tapered on one side..  

Johnny I didn't know you wuz ah bolojister..

Tapered is tapered. The only way the piece would know if it was done 'evenly', by removing material equally from both sides, would be how the ground angle relates to the butt end's square cut on half length lams... virtually meaningless since the difference is so minute, and they're generally recut at an angle to be spiced anyhow.

I grind, flipping them until all saw marks are removed, then grind to thickness and taper.
