Tim T Posted April 12, 2023 Report Share Posted April 12, 2023 (edited) I have managed to remove all but one of the control knobs from the switch plinth on my 5 project without too much trouble, however the heater fan control knob will not budge! I can feel the sprung button moving when I depress it but there is no sign of the knob moving off the shaft. I don’t think that it is glued… does anybody have any bright ideas please. I am hoping to re-use the original switches! Many thanks, Tim Edited April 12, 2023 by Tim T Typo Quote Link to post Share on other sites
PodOne Posted April 12, 2023 Report Share Posted April 12, 2023 Hi Tim Bath of penetrating oil for a day or two? Ultra sonic bath/cleaner? Andy Quote Link to post Share on other sites
BaulyCars Posted April 12, 2023 Report Share Posted April 12, 2023 Hi Tim, I have one that also refuses to come off unless I use the fattest pin that will fit in the hole (an allen key works sometimes) and push it in hard. I have to push and pull to get it off. Some sweating and light cursing also required. Regards Toby Quote Link to post Share on other sites
Paulfc Posted April 12, 2023 Report Share Posted April 12, 2023 As said above, try and get some oil in there. I wrapped an oil soaked cloth around the knob and left it for a few days. If you’re able to twist it so the pin hole is on top that helps. Also, sometimes it sticks because the greater pressure for the last fifty years or whatever has been applied by the pulling motion. Try gripping the spline and gently tapping the knob forward. Have to say, took me a week but it eventually worked. Quote Link to post Share on other sites

PodOne Posted April 12, 2023 Report Share Posted April 12, 2023 Is this some rare snake oil to only be removed from the locked cabinet in case of emergency when all else has failed or is it really worth the money over Plus Gas? Andy Quote Link to post Share on other sites

Motorsport Mickey Posted April 12, 2023 Report Share Posted April 12, 2023 (edited) Andy, It says on the tin " Loosens the toughest, stuck together metal parts - or your money back" I've never yet asked for my money back. I think the line on the can that says "For cleaning guns, rifle barrels parts and tools " probably gives a clue, spray it near a joint line and it positively sprints into it and disappears, I think it's based heavily on a gun oil formulation, and for me it works. I last paid £17 for a standard sized aerosol and I'll do the same again when it's used up, you use whatever "snake oil" you want. Mick Richards PS: Stuart thinks it's good as well.

PodOne Posted April 12, 2023 Report Share Posted April 12, 2023 Fair enough comment Mick I'll treat myself and give it a go better than perhaps breaking things. Quote Link to post Share on other sites

Motorsport Mickey Posted April 12, 2023 Report Share Posted April 12, 2023 Just now, stillp said: I couldn't find any that cheap. Pete I reckon it was maybe 3 years ago when I last bought it, no idea what the cost is now, I'd better start saving. Mick Richards Quote Link to post Share on other sites

ianc Posted April 13, 2023 Report Share Posted April 13, 2023 It's clear from what Mick says that Kroil will free any and everything, but is really expensive. However, Plus Gas is available in aerosol and in liquid form from Screwfix (328HT) at £5.29. Ian Cornish Quote Link to post Share on other sites
Tim T Posted April 13, 2023 Author Report Share Posted April 13, 2023 Well I am going to give the Kroil a try and will see what happens. This YouTube test didn't fill me with confidence though. Many thanks for all views. Tim Quote Link to post Share on other sites
