Hi sebg
We did see your email sent at 4.42 this afternoon - you may have noticed our opening hours are 9.00-4.30 - so I would appreciate a little time to try and help if possible; I have emailed WoodRiver in the USA to ask if they have had any similar issues and await their reply. I have never suffered any blade chipping issues with my WoodRivers, nor have my students who all have WoodRivers in their tool kits.
You mentioned in your post that the WoodRivers were closely priced to the Lie Nielsen’s, of course I am happy to offer you a no quibble refund in full, but I’m pretty sure the LN's are more than twice the price of WoodRiver planes.
I am confident in the quality of the planes but there may be an issue with your blades. Can you advise what timber you are using? It looks to me like carcassing pine, usually used for stud partition walls, not something I would personally use any quality plane over, be that a WoodRiver or a Lie Nielson.
Your bevel up planes would cope better with the knots as they are set at a much lower bedding angle, this attacks the timber in a different manner to standard bench planes with a bedding angle of 45 degrees. Are you able to regrind, sharpen and try some other timber. I am not convinced that throwing more tool money at knotty pine is the answer? It would be really helpful to see a couple more photos of how you have set up the blade and chipbreaker, if you are able to upload them please?
I am always happy to assist customers wherever I can and replace or give full refunds if there are any issues with our tools, we pride ourselves on our customer service, so please give us a chance to sort out your issue.
Cheers Peter
