Silvey Razursharp Advice

[TreeJob]

Howdy all,

New member hoping to get some advice on my new-to-me Silvey Razursharp. Previous owner redid the slide blocks/bushings but it still seems to have a little bit of drag/hang up. Going to play with the centering some more as well as lubrication.

Any other recommendations?

Started my own cat logging operation in NW Oregon this year and am looking forward to some good fast chains coming off of this grinder.

@Skeans1 is your guy for that.  


That a standard root rake pinned on or modified blade? Nice machine.. D4ish?

[TreeJob]

Thanks! It's just a pin on. It an 89 D4c Series II. Definitely no D4H, but it works great for what I've been doing. 

[mike_belben]

I seriously considered a D4C but it was pretty tired and seller wanted pretty good money.  I ended up with a d31 komatsu for lot less that ive been happy with.  That high roller winch would be nice though.

According to Madsens, that Salmon colored grinder wheel remains one of their best sellers, but the white colored one makes for the easiest to setup for "proper" square grind because it allows you to see the corner of the chain for the best decision. HOWEVER, for the nicest finish of the cutter teeth, many believe the blue wheel to be the best. According to the 2019 catalog that I have (the newest one for me, and where I'm using their description almost verbatim, the prices are: the first 2, about $18. The last, about $40).

If it were mine, I'd wear out what you got, and then go for the white.

DON'T overheat your cutting teeth when you go to grind them and then expect miracles. Take your time, be patient. Remember that when you grind, it should be bzzt, bzzt, bzzt. And not bzzzzzzzzzzt. If you do that last one, be prepared for a new chain purchase!

And EVERYONE covets the Silvey, they are no longer made. Take care of it, don't drop it, and you'll be good to go. And if you need parts for it, it looks like Madsens would be MY first place to look.

If it doesn't already swap the dressers out for the multi point ones it'll leave a much nicer finish on the wheel. What's exactly sticking the slide? If so does it do it on both side?

That wheel info would also depend on the wheel manufacturer, I've ran the Salmon, the blue, the gray, and now the white wheel. All produce a nice tooth with this white wheel producing the nicest finish without any wax imbedded. If you do a long grind yes you'll burn the cutter but you're not going to need to buy a new chain it just means you will not be able to file that tooth.

Do these use a dovetailed gib adjustment with a brass slide like a milling machine or mag drill?

It seems to be sticky on the right side in particular. I need to look at the slide set up a bit more.
Previously I have used a Silvey Swingarm of my Dad's so I've had goodluck with square grind results. Just need to get acclimated to this machine!

I took the slide block apart today and cleaned out quite a bit of junk. Having a tough time getting the gib blocks/aluminum spacers to stay in that the previous owner installed.

Should there perhaps be counter sunk holes on these?

[mike_belben]

Hard to say what should be in something ive never seen but it is not uncommon for a brass wear strip in a gib system to have a depression for the set screw the engage into so that friction doesnt drag them out.  But there are other ways to retain them too so i cant know if yours are missing a piece or whatever.  What matters is you get it serviceable, not that you get it restored to OEM.  Skin that cat any way you are able.  

[Old Greenhorn]

Picture? Is the gib tapered? If so there should be an end screw to adjust it in and out. If it is flat then does it have a few side screws with lock nut's to adjust tightness? If so, then yeah the should probably be a retainer hole of some sort to hold the gib in place.
Not home so I can't look at the IPL, but not would I love to have one of those!
