- We fixed the bug that the thread could not be fixed on the pole, there will be no problem in the current batch
- But I want to remind that the inner diameter of the fisheye bearing is 6.0mm, which is suitable for the passage of stainless steel rods below 6.0mm. According to our communication with Ruixin Company, Some of the rods of Ruixin Pro RX008 purchased before March 2022 The diameter is more than 6.0mm (about 6.1mm) so our suggestion is: it is best to measure the diameter of the stainless steel rod of the rx008 in your hand, and then make a purchase decision. Thank you for your cooperation and happy shopping.

—Edit—The locking screw to the vertical shaft does not lock very tightly at all. This permits the unit to wobble back and forth during operation. In addition the picture depicts a chamfer around the drill hole to the shaft, this is no present on my unit either. If the locking screw had more grip this would be a 4 star item.3 stars for being close but not exactly what I need.—Original Review—The shaft has to be precisely angled to go into the hole, so it’s not undersized at all! Almost /r/perfectfit material. Some reviewers said they made have had to sand the shaft, but I didn’t.The shaft tends to stick to the spherical ball bearing a bit. More specifically during a stroke, the shaft will pass through the ball bearing just fine, but touch the wall of the bearing holding the ball in place and cause some jerky motion. To solve this, use a bit of mineral oil to lubricate everything. It should be fine.

I’ve been a machinist all of my life… And this is some of the worst machining I’ve ever seen. Poor quality control! The threaded hole for the locking setscrew, was drilled too large, so when it was tapped, there were barely any threads existent. First time I tried to tighten the setscrew, it stripped right out… Barely finger tight. Anyway… Now I get to redrill and tap this piece to a larger thread size. I may be able to still salvage it… But I’ll also need to buy/make a new setscrew as well. For all other people who don’t know how to machine… Stay away from this junk.

The parts look great till I install it. They need to enlarge the hole to 6.1mm not 6mm like the rod. Suppose to be a slide fit not interference fit. Lol

The knob that locks the position on the main rod does not tighten up and the setting will slip if you donβt use the adjustable set stop that secures with the Allen tool. Otherwise it is a pretty good upgrade from the plastic ball .

…you need to exert a good bit of force to get it on the rod due to a little sloppy machining. Once it’s on, it works great! Just leave it on when disassembling. If I could suggest a modification, make the mounting screw hex key tensioned, it’s very difficult to get it tight enough with only your fingers.

Overall working good seems sturdier over the nylon swivel. Only thing I don’t like is it doesn’t come with directions. So you have to use it However you decide it works. There is an extra bar hook looking thing. It may be a guide or some kind or rest to hold up sharpening tool when removing knife. I really don’t know because original RUIXIN PRO RX-008 doesn’t have that piece. So I’m using it as a rest.Overall I bought it for the swivel. I haven’t used the original swivel that came with the RUIXIN PRO RX-008. However, I bought the upgrade because the reviews on the sharpening tool complained the plastic swivel wears fast.

I’ve had a problem with the Ruxin pro knife sharpener since I first got it a couple of years ago–the pivot just won’t stay in place and must be adjusted every 15-20 minutes. This gadget fixes that very well. I used it for 6 hours steady and it never tried to rotate around the vertical shaft. I checked the angle for every stone grit and it never moved at all. I like the rod clip a lot also, I almost didn’t install it, but it is very helpful.

The new joint fits the machine and doesn’t do much more than the original
