I've been having a hard time trying to tune carbon arrows to my Tomahawk Diamond longbow, 48#'s at my 29" draw. Tried both 500 and 600 spined with a variety of point weights. So, I need to scratch from scratch and  try to tune the bow to the arrow. Can someone explain how to do that, thanks. Toby

Do youre arrows show weak or stiff?
Or whats the problem?

By building out the side plate you can make an arrow thats too weak fitting and vice versa.

By raising the brace height you can make an arrow thats slightly stiff fitting and vice versa. But thats more fine tuning.

Much more information is needed.

Specific arrows with length and point weight.

bareshaft information?

nock height, 3 under or split.

Etc.

use the like hvyhitter posted.  it works!

I'm trying to tune the bow to the arrow, not the arrow to the bow. I have both 500 and 600 spined shafts, 30"s long.

Raising the shelf and or building out the side plate. You can use tooth picks and shave down to get the width you need or some use paper match sticks. A little side plate width or shelf hight goes a long way.

Since we are guessing on limited info, I'd say build out the side plate to allow the bow to shoot the 500's. They are showing weak bareshafted, right?

A bow really dosent have a lot of lattitude to use in tuning, just adjusting the brace height and building out the shelf. Usually tuning the bow is done as fine tuning to get broadheads and fieldpoints to hit together. If your arrows are way off you probably wont fix it by anything you do to the bow.

I thought that in the "old days", many archers tuned the bow rather than the arrow, I find tuning carbons difficult, probably my fault, so thought I would try the tune the bow route.

You only have a limited amount of range when you tune the bow instead of the arrow (personally, I tune both). You can make an arrow act stiffer or weaker by type, amount, and placement or string silencers, brace height, and centershot. If you're shooting with a plunger, add plunger tension as well. Nock high or low is controlled by your nocking point location.
