Chronos Ring Roller
I bought this off another forum member recently and the rollers looked like Marty Feldmans eyes, all 3 were looking in different directions. The gears also felt like they were not meshing correctly too, very rough in operation. After a good wash and all the protective gloop and grease was removed it became obvious that this was not due to wear or damage but how badly the machine was made.
Gear meshing incorrect as not parallel to each other.
Spacer/bearing out of alignment
All three shafts are not parallel to each other.
Threads not cut squarely.
How do they get something so simple so wrong!
This is after I deburred both parts!
I think this is to partially compensate for the spacer above being so far out.
The base plate bolts against these two faces which have a 1.2mm height difference.
The gears and rollers have been eating their way into the side plates. One M6 screw for the gear guard is too close and also being nibbled by the gears.
My personal favourite, the main culprit. Only one of the three main holes can be lined up perfectly hence the rollers all looking in different directions!
I think my conclusion could be poor manufacturing, what do you think? There are one or two other parts misaligned or poorly machined that I have not shown. I am going to fabricate a new pair of side plates for starters which should give a good basis for having parallel rollers then fettle the rest of the faults.
