Hi all,
I recently spent a happy day in the workshop disassembling, oiling, and reassembling my newly acquired Kity K5.
As part of the referb, and because I have a project coming up, I decided to get a new blade for the Saw, and I hit a snag which I'm hoping someone may have seen before.
My new blade is 195mm diameter, with a bore of 30mm. To get it to fit, I also got a reducer washer to take the bore down from 30mm to the required 15mm.
The problem is that when I put the arbour back on and do up the bolt, the blade is not held fast. I took everything apart and it looks like the face of the removable bit of the arbour is slightly convex. This means that when I do up the bolt, the centre touches before the outer edges. As result the reducing washer is clamped nice and tight, but the saw blade can rotate freely, basically spinning on the reducing washer.
TBH it seems a bit unlikely to me that the arbour had bent, it looks like it's a cast alloy and I would have though that was quite stable and more likely to crack than bend.
I wondered if anyone had come across this before, or had any suggestions on how to fix it?
I was thinking that I could; replace the arbour; add some sort of large rubber washer to hold the blade, try and find a blade with a 15mm bore.
