Well I've got way less than a new swing arm in both of these. I sold the swing arm and bought 2 RZ II for $540 and the 600 for 500 rounds of wolf 223 ammo. The deals are out there like that simington. If I didn't buy a few other things already I would have it here.

This is SRCarr's Razur Sharp II after he trued up everything and made a new slide using cam followers on a red neck milling machine using a heavy drill press and a HF feed table.

I'm hoping Uncle Sam will give me enough back in the spring such that I can upgrade to a real milling machine.  For now... the cross-slide table works, small bites at a time.

I like the idea of a mist coolant for those rocked chains.  The extra heat breaks down the epoxy in the wheel and causes more wear.  Also the coolant might fight the stone loading issue.  I still think you'd have to at least dress the lower face when changing grind directions as the salmon stone I use seems to seal over and will only cut one direction until re-dressing.

This may be a very significant observation to remember?

That one is real nice looking. A few have tried to contact the seller with no response yet.

I don't see any boots on the slide which is a good indication that it is worn completely out.  If not it will be soon running it without boots.

Good catch . . . .

For sure, no boots or bad boots, and the slides are worthless in no time.

Since the first of the year, Silvey Chain Grinder Company has shut down at first claiming like it was a seasonal thing but it turned out to be for a undetermined amount of time?

The folks where the Simington 451C grinder is made have jumped on the band wagon and thrown up a website with some nice videos with owner Kelly Peile demonstrating and trouble shooting the Simington 451C. It is nice to see Kelly's ideas of how to tune up a swing arm grinder and some of the cause and effect relationships. Kelly has a nice, easy going manner and is easy to understand. Though he doesn't give exact settings, angles, or dimensions, he does express his ideas of the inter reactions of various adjustments on the grinder. I think that it is important that all of us with square grinders review these videos . . .

Here is the website address. The man in the videos (Kelly Peile) is very good at explaining his product.

660mag that chain you did on your grinder looks sweet. Hope to put in in some wood someday soon.

LMK how it does after you get it limbered up. We might could change something about it if we have to?
