Can anyone tell me what is the difference between a cast and machined riser? The higher end bows in some of the bow lines have the machined riser versus the cast on the lower end bows. Example is the Darton maverick is cast while the Darton renegade is machined. Does it really make a difference?

It does not make a practical difference.....in terms of performance, endurance, etc...for most of today's normal setups.

I would refer you to the thread link below for some excellent information on the subject....

The Maverick does not have a cast riser, it has a forged machined riser and is one of their best selling bows. The die cast risers start on the action series bows with the Striker wich I think is thier cheapest adult bow.

Machined risers are stronger and straiter than cast, they are also more uniform in the over all quality of the metal. That does not mean a bow with a cast riser will not shoot well or take deer. My buddy has one the old mavericks with a die cast riser and does very well with it. But it heavy, loud and vibrates like mad when you shoot it. I don't know it that has anything to do with the riser material though.

From what I know, cast risers have very sloppy tolerances, like for example limb pockets, which should be very precise to add more accuracy to the bow. Cast risers are also more prone to air pockets, and contaminations in the aluminum making for a bow with less strength then a forged or Machined or Forged Machine riser. Machining is usaully done with a solid bilge of aluminum be it 6061-T6 or any other equivilent. The bar of aluminum has very little if anything in the way of air pockets, and or contamination. Machining is very precise ask any engineer about .00001 tolerances, limb fittings are precise, accesorie fittings are precise, and you don't have to worrie about stripping the fittings out because of soft aluminum or poor fitting measurements. Forging, it's what they do to strengthen the metal in swords. After forging aluminum you are left with very little in the way of air pockets or contamination in the metal, the molecules of the metal are actually pushed closer together, making for great benifits in strength, even more so then simple machining. When forging and machining you get the best of strenght and precise tolerances and fittings, High country and I beleive darton both Forge and machine risers. I think the most any bow that is machines is very very strong, as is forged machines risers, Im not a big fan of casting though, because I got up close and personal with the inside of a old PSE cast riser, and did't like the look of it very much. Good luck on your findings and good shooting.
