*WARNING* Pattern chipper blades

[Rowden the cowboy]

I don't know what your experiences are of using pattern blades in your machines are, but i'm posting here as a warning. I own a TP760 and have had 3 blades literally fall apart on me in the last three months. These blades are from a reputable supplier of pattern blades that Im sure many of you use.

 

I had one blade split down the middle, no damage done to the machine and it was close to the wear line so I just put it down as metal fatigue.

However, last week I had a second blade do exactly the same thing, again no damage done to the machine but this time a large lump of the blade had gone missing and these blades had only had 2 sharpens, max.

 

At this point I took all of our sets of blades down to Osbornes for them to have a look at them. I went to hand the owner a blade from the third set of blades and the whole thing literally fell apart in my hand! All these blades were from the same supplier. Needless to say, I have discarded all of them and bought genuine TP blades now.

 

I would urge caution if any of you are using these blades in your machines, as it was only down to luck that no damage was done to my machine and no one was hurt. Also, the blade mounting system in a TP760, which is unlike many other machines, would have played a big part in the whole machine not being damaged. In a new generation TP or a Jensen, the damage would've been fairly catastrophic.

 

If anyone else here has had similar experiences let me know. Personally, I will never use any knives other than genuine TP ones again.

What has the supplier said?

That is very worrying!

Is there any possibility that the flywheel mounting is damaged/out of line and the blades have been stressed when fixed to the machine? I am unfamiliar with TP machines so don't know if this could play a part or not.

odd i had this as well but it was the genuine blades that fell to bits

We sold a large amount of blades back end of last year to replace pattern blades that had failed on Bandit machines, we were also lucky due to our build that no damage occurred. There were so many failures that the company has stopped production on these.
