A laminator has plastic wheels to drive the rollers that pull the
lamination pouches through heated rollers. If somebody puts something
in that's too thick, the wheels break. I have no idea if spares are
available, but probably not on a Sunday.
I wasn't sure if epoxy would stick to the wheel but I repaired it
anyway. But I'll bet the repaired tooth breaks soon - they always do.
Since everybody will tell me that I can't make gear wheels I thought I
would see if I could. We have no indexing head or anything to make
gears with, so I cobbled up a holder using the old gear wheel which
has 21 teeth. If it had 16 teeth I could have made an indexing plate.
But how do you space 21 holes around a circle?
Here's the broken gear wheel on the left top, and after I repaired it
with epoxy resin, at bottom left.
On the right is the piece of plastic that I turned up on the lathe,
and after I cut the teeth in it using the mill. I considered using
brass but I found this black rod that seems to be some exotic very
I couldn't find any suitable cutters so the teeth are the wrong shape.
It doesn't seem to make a difference to the horrible piece of
engineering that it's going into, the one that broke in the first
The gears still go around OK.
Here's the setup in the mill:
I discovered that the holder in the mill has to be very accurate. The
hole in the middle of the gears is 7mm and I don't have any bolts that
size and I didn't want to stop and make one. So there was too much
Now I think I need to buy an indexing wheel for next time!
