Default Re: The mouth of hell - a KB MR10 story

That certainly looks in place in your kitchen and a lot safer than a DAC90.

All the knob spindles were broken on mine. I removed what was left of the spindles with side cutters and a mini grind stone.

A hunt through the knob boxes turned up three with stouter shafts. The holes in the MR10 case were more than big enough to accept these. The knobs themselves were unsuitable for the MR10 but they could be sacrificed for their shafts!

The tops of these were cut off just leaving a thin disc of the control knob itself. With the aid of a G clamp to hold it central, resin was poured into the rear of the original knob front forming a very strong fixing..

Even after lubrication the waveband switch was rather stiff. An Aluminium spindle extension coupler was employed in this case with one end filed into a 'D' shape to prevent it rotating in the hardened resin. [impossible!] Care has to be taken to line up the coloured dots with the index mark on the cabinet side. Secured with it's twin grub screws the feeling is very positive.

This method could of course be used with any control knob with suitable modification. Poundland's twin tube adhesive also makes an alternative fix in place of the resin and it is very cheap.

Regards, John.
