Home sharpening timber wolf blades

Recommended Posts

I have recently bought a decent used wolf 190.

Best move I ever made, it's a real beast compared to my Greenmech.

I have fitted new blades, but the old ones look as if they'd sharpen up quite easily.

I have a Tormek grinder and plan to sharpen them on this as it puts a beautiful edge on axes knives and chisels.

My question is regarding balancing of the blades. If I home sharpen them they may well finish up one lighter than the other, if this is the case, will the resulting imbalance cause excess vibrations when in use?

My reckoning is they are already a couple of Grammes different just as a result of wear and the odd stone chip.

Any ideas on this as I am keen to get more use out of old blades but not on fitting new flywheel bearings if the whole thing shakes itself to bits.

IMO is it so cheap to get chipper blades reground professionally, it is barely worth the time and effort of attempting to do myself. However if you do have the tools and experience, then whynot have a go. If your worried about the varying weights, then a set of scales to check each one is the same would solve this?

I think yes, keep heat out of blade when sharpening keep them even size and same angle of attack, weigh them I guess your sharpening stone is water or other liquid immersed should be ideal, good saving

They have to be quite a bit out to make much of a difference. You should be able to get the blades to within a mm or so of each other and the weight difference would be insignificant.

 

I doubt that older machines are that well balanced anyhow, try taking the blades off and spinning the flywheel, mark where it stops and do it a couple more times, it will probably stop at the same place.

Timberwolf blades are concave and have to be specially ground rather than flat ground, this is how the machines were designed to run.ImageUploadedByTapatalk1343389759.694696.jpg.f3a05fc49742e353b11aded1f3b480c8.jpg

I bought the Tormek T7 a while back and this jig is next on my list

 

Buy Tormek SVH-320 Planer Knife Jig from Axminster, fast delivery for the UK

 

It will do both of the 4 inch blades at the same time so no worries about balance :thumbup1:

 

You should be aware that jigs for the Scheppach wet grinder is often a lot cheaper that Tormek. And they fit. Reason being that Scheppach and Tormek is made by the same company, with Tormek being the pro-brand (expensive).
