If we get some warm sunlight I'll make up a 60DL one? Might be a couple weeks?

Economics 101

The new Simington 451C Grinder right now is $800 with free shipping all adjusted and ready to plug in and grind from the factory.

Also right now there is an old style Silvey Swing Arm from 1977 that has a few minor locally available parts missing and no stand for $600 + $30 shipping on Ebay. You will most likely need to put a wheel on it too for probably another $25 when you consider shipping? Don't forget you need a stand might be $140 with sipping if you buy one? It probably needs some tune up adjustment and shimming to get it to grind properly?

Now which one would you buy?

Very good read Jim, and no doubt your research shows in your chain. Very very nice looking chain I saw the other day. Even a guy that isnt into square can see the nice crisp angles, and perfect placement in the corner of the tooth. Well done indeed!

All I have is a 1979 early style Silvey Swing Arm.

I bought it used from a member last fall and cleaned it up/replaced most of the fasteners with Allen bolts and put new bearings in the arm pivot for one was busted. I attempted to tune the grinder up (side to side) by tilting the arm as they are designed that way but had more success at putting a 5/8" Oilite bushing in the pivot bolt cavity of the base to zero the arm and then I shimmed the motor to the arm. At fist, I loosened the motor and put two 1/4" flat washers under two bolts on one side of the grinder but that was too much. So then I tried a business card but it was not enough, so I used two thicknessís of the business card and that was mighty close side to side. As far as I'm concerned, it is as good as a new one to me. I can raise and lower the grinding wheel arbor on the motor to effectively change the arm height if I so desire. I can move the chain holder back and forth a considerable amount (it is slotted) to allow for different inner angles. The dressers were set at 80 and 20 degrees when I got it and with the chain holder in the middle, it puts some good angles on LGX chain.

Watching Kelly Peil's videos, the Simington 451C seems mighty good to me and he has a good price compared with a Silvey. One thing about a new one is that no kid has played with it and run the cutter stops into the wheel and ground them half away or compromised the main frame structurally with some hair brain idea as I have seen done on some of the used Silvey and Simingtons for sale?

In spite of what some of the guys on the Internet say, the old style Silvey was first and in a business slow down, Simington bought the Swing Arm and Razur sharp I designs, patents and all, from Silvey. So the Simington 450 is almost identical in every way to the Silvey. Simington eventually sold the Swing arm and I think Peil is at least the 3rd owner of the Simington line. One of the owners decided to update the design and came out with the 451. The 451 has a TEFC motor. The old original Dayton motor on the early Silvey and Simington 450 is no longer available as it was a 56 frame, 1/4 HP Split Phase, 1/2" shaft, cradle mount, ball bearing, 1750 rpm motor, that was mounted to the grinder with the end bell bolts. The newer Silvey's have a C face - drip proof motor. I think the new motors are a 48 frame?

Overall, I think the Simington 451C is a better deal than the new style Silvey for it has a better motor and is more easily adjusted. Besides, it is cheaper out the door.

Wow 660mag that was good.   You presented some good points and the reason I ask is I am considering on purchasing one the new ones from Simington.   I have tried calling them several times but have not been able to get a hold of anybody as of yet.  Thanks Roger
