CT 100 Plastic Yoke Cover Problem

[blacksmith]

Hi folks,
I could probably make the part in question if I had access to a good original. There wouldn't be any damage or changes to the original in the process of making a mold.

I would have to know the temperatures the plastic part might reach in use. Maybe someone with an infrared heat sensor could take a temp reading of the part on a set that has been working for a few hours.

Can the old cover simply be removed from the yoke and a new repo be attached? I assume the repo cover would have a longer life than the original RCA cover. Of course the set would be unplugged during this procedure.

It snaps in place. Two small square cutouts -- one just above my index finger-- mate with dimples on the yoke body. There are also two half-moon cutouts that match similar shapes on the yoke body to pass the yoke wiring.

Upon closer inspection, the lower half of the cover has some warping. Due I suspect to stress rather than deterioration of the plastic. Since the two notched-out areas are identical on each half of the cover, the stable half describes the whole. Perhaps that is enough for a cloning?

Can someone with a 15GP22 set make the temperature measurement if/when it becomes necessary? I do not have an IR thermometer.

If the warping is minor, I might be able to duplicate the warped one, then manipulate the copy to get it back into shape, then make a mold from that one.

Is the yoke diameter the same as the ctc4.

The cover will be in the mail this Monday June 11 to Ed for evaluation.

Spoke with John Folsom earlier this evening and he brought up rcafan's post. John did confirm that his yoke cover fit both the CTC2 and CTC4 yokes.

Might be able to sell it to the larger CTC-4 owner base as well.

This might be too simple-- home depot sells in the paint department
A plastic cover for paint can that happens to perfectly fit perfectly on
My ctc4 yoke. Snaps right on.only needed to cut center hole.

Clever alternate solution Neil -- there is the inexpensive 'utility' cover or a 'clone' look-alike with original RCA-design characteristics such as the concentric ridges.

Update: Ed has the cover and will work on the reproduction this August. Turns out the cover is thinner and less heavy than he expected, which may cause him issues.

I used Bob's method with styrene sheets.
Doesn't take too long, and is quite simple.
I used a pair of snips, and a drill for the center hole.
This is a before and after of one I did not long ago.

Certainly nothing wrong with that. Nice job...
