Wolfgang sells small appliance but does not have any cust support.
I have a convection oven at the bottom knob, black, 2" dia, 1/4 slotted shaft and the plastic shaft was not supported by a metal ring so of course the plastic slot evidently crack making the entire oven useless, unless I can repair it or get a new knob that will fit.
What I think may help is he metal sleeve that is like a round clip that some plastic knobs have on the end or the shaft to support keeping the slot from breaking off. I dont know where to find these but have seen them before.

Anyone help with a black plastic knob, 2" dia, 1/4" slotted shaft or the metal round re-enforcment clip that goes around the 1/4" knob shaft?

pictures attached.

I have the exact same problem and need the same part. Have you had your problem resolved? If you have, please let me know. Thanks.

I purchased a shaft 1/4" or 6mm in dia off the internet for repairing radios.
I also purchased a brass coupler where the shaft and the shaft I purchased can go in each end and are held by set screw.

So, I attached the coupler to the shaft on the shaft of the timer and set with set screw.

I took the shaft and cut it to the length of the inside of the couple to the inside of the know as far as it would go. Depending if the shaft is 6mm or 1/4" you may have to drill the know inside to get it to go in.

I cut the 2 wires from the lite in the knob to remove the old knob.

but you may not have to do that but if you do, you can re-soilder the wire back together.

I then inserted the knob on the new shaft and glued inside, you can use Gorilla or super glue and push it on to where the knob and the oven are equal.

that is it.

The cost was mainly the coupler used to repair RADIO knobs and was about $5-10 for shaft, coupler and shipping but couplers to join the two shafts together are common.

It sounded quite complicated. I am not sure if I am able to do what you did. In any rate, could you tell me where you got the parts, knobs and couplers. Thank you very much for your reply.
