hello people, i have a quick question i hope someone can help me with, i am building a grinder similar to the no weld ones, am i able to use idler wheels all round on the thing or is there a reason that i do need to use a drive wheel off the main shaft or will a idler wheel suffice????
 
The drive wheel doesnt have any bearings and is just a machined hole usually with a machined key way in it.
 
quint nailed it, the drive wheel would not drive anything if it had bearings in it. the drive wheel is
a solid axle that turns the belt.
 
just coming back on here to retract my question haha as i seen the motors have a shaft with a notch part on it and thats why the drive wheels are needed..... Thanks anyway fellas
 
You're welcome. BTW, I think it's worth the $26 to buy the plans to the NWG, there is a wealth of information there.

dont need the NWG plans ive already deigned my own, i also dont need a drive wheel as im not running the system straight from the shaft of the motor but from a shaft attached to a pulley so im right using idler wheels also, i was just thrown off for a second by wheel options but shes all sorted now!

But you're using one drive wheel right ?
 
Yeah I don't think there's anyway around using a drive wheel. Your belt won't do much grinding if you have an idelr wheel on your drive shaft.
 
Perhaps he has a driven contact wheel ( which is also the drive wheel) ?

For sure, one wheel needs to be powered.

Post your drawing and lets see what you plan.
 
sorry for the confusion people, this ones been confusing me too, the motor has a pulley attached to it which goes to another pulley, the other pulley is attached to a shaft running through two pillow blocks then on the end of that yes....... im needing a drive wheel ;)

while im asking other then the $60 ones of the knifemaking stores any cheaper ones online floating around?
 
IMO wheels are one thing you shouldn't skimp on if you are building a grinder on a budget. I originally thought I could build a grinder for around ~$700 but i've got about a grand in mine and I'm glad I spent the money on better stuff. Precision cnced wheels are going to make everything run a whole lot smoother than trying to deal with caster type wheels which may have balance and bearing issues.

That being said "cheaper poly wheels" from www.sunray-inc.com seem to be quite popular with some people and they have had good results. Their drive wheels have a poly outside but I don't think that makes any difference from a straight aluminum one.

Good luck on the build!
