Square grind wheel finishes

I dressed a couple wheels tonight and ground a tooth with each to take a picture to show the differences.

Blue ceramic


salmon


gray waxed

I'm seeing several other variables.

The inside vertical with the small salmon is a little on the sharp side.

The blue wheel is best overall finish to me?

It is probably camera color reflections but do I see a little blue on the gray waxed?

Inside angles are blunt with the white but would probably work well in the woods.

Camera angles cause distortion and outside vertical on the blue wheel looks wrong on the left cutter and correct on the right cutter and I know the vertical dresser angle would have likely been the same on all the wheels.

Nice cutter pictures and excellent attention to the beaks.

Maybe do a 60dl of each one and test out of curiosity?

Part of my inquiry is wanting you to elaborate on the problems associated with changing to wheels of different diameters and having to move the slide assembly back and forth with the Razur Sharp II ? And what I can interrelate to my Silvey Swing Arm.

I could do that Kevin if I had some 60 dl left. I sold all the chain I had here the other day and could have sold more if I had it.

I just dressed the blue wheel tonight for the first time. I had the gray one on there since I wanted to try it on a rocked chain. There is wax stuck on the cutter that was ground by the gray. I didn't notice until I was already editing the picture to downsize it.

The salmon is down to the end of it's useful life so I couldn't get the gap I wanted on the chain holder to wheel. That piece of chain is scrap and what I use to test different wheels and angles before I actually use it on a chain I'll run. The right side weren't even ground on the same grinder.

You can slide the whole assembly in or out to keep the chain holders feeding in on the same angle all the time to keep the top plate the same angle. I don't know if it makes sense and if it doesn't I'll take some pictures and edit them to try to show what I'm saying. The swing arm where the chain holder can't slide in to compensate for the wheel wearing you're going to keep intersecting at a different point on the wheel from where you started when the wheel was new. It will change your side plate angle and top plate. If I was a photoshop wiz I might be able to help you more.

No problem. I just hope you understand what I was saying. I even asked my wife how to describe what I was showing her in my crayon drawing. :D

I got it.

I've been thinking a lot about the interrelationships of the approach angle with varying wheel diameters.

My older swing arm, I can move the chain holder to the rear from centered on the fastener but have not played with that yet.

I have two salmon wheels, one from Silvey and a Molmab from Bailey's. I have not used the Molmab yet.

From what a couple people said the molemab aren't as good as the pacific/madsens wheels. The older swing arm should give you more flexibility in chain angles for softwood or hardwood or to get closer to race chain angles.
