Shaft adpater ideas for input selection and volume?

nick_g_evans · 29th May 2008, 01:08 AM

So I ordered an enclosure from www.diyenclosures.com and it came with knobs with large holes for the shafts, but the volume knob I ordered, the Panasonic EVJ-C20, has a smaller shaft, and the input selector, a Grayhill 56D30-01-2-AJN, has a ridiculously smaller shaft.

Does anyone have any ideas or suggestions?

I don't have much information as far as measurements right now since I'm at work. Also, I can't remember the enclosure manufacturer.

Here's the parts I ordered:

I made my knob using a spray cap and a piece of wood which was cuted to fit inside the cap. The hole for volume knob will be made by you and it will fit perfectly on the selector and pot. See here how it looks:

Make your own extender rods from aluminium rod the same diameter as the knob holes (probably 6mm or 1/4 inch). Then carefully file the other end to the same diameter as the shafts on the pot and selector. Then make up a connector to join them together.

Or - buy another vol control and selector with the same sized shafts as the knobs.
