A 3D printed FRG-7 light and power switch knob

Lex PH2LB All Messages By This Member #155 Hello all, "The switch knob is gone, long life the switch knob." Got a new Frog in the workbench in a fare condition, but needed a lot of cleaning (dust and other unidentified stuff and gore) and?also new knobs on the light and power switch. Which are very hard to get.??So I pulled of the knobs of my other FRG-7's and it turned out there are 2 models of the knobs (left is original, right is the later model). I liked the original model more so I fired up TinkerCad and started drawing. And the second prototype was spot on. ?Needs a little trimming on the edges, but looks good already and it functional (grey is original knob, white is 3D printed 0.12 layer, 100% infill). Next steps : order roll of red PLA to print the power button. print a few more to see if it really is working. publish STL file on my website (link will be post here). When the results are reproducible, I will post the design on my website (and the STL in the file archive of this group). So when you get your hands on a FRG-7 without a light or power switch knob, you know can print your own.? -- 73 Lex PH2LB?

Russ Norwood All Messages By This Member #159 开云体育 I second what Randy said.? Terrific work. ? Makes me want a 3D printer even though my FRG-7 has all the original switches! ? toggle quoted message Show quoted text From: [email protected] <[email protected]> On Behalf Of Claude F4IKH Sent: Tuesday, February 22, 2022 6:36 AM To: [email protected] Subject: Re: [Yaesu-FRG-7] A 3D printed FRG-7 light and power switch knob ?

Steve Quigg (VK2TUM) All Messages By This Member #160 have a look at the document in /g/Yaesu-FRG-7/files/4%20-%20FRG-7%20Service%20Notes/FRG-7%20Switch%20Notes%20v1.0.pdf for notes on replacement switch levers. These are not the same as the 'original' rounded-skirt levers, but ARE original on some (many?) receivers. A friend of mine has an FRG-7 which he bought new here in Australia back in the 70's (still in original condition), and has the straight-skirt levers.
Lex PH2LB All Messages By This Member #162 That is excellent info Steve. And looking that there is a replacement (although not in grey) for the straight-skirt?levers I keep to the rounded-skirt levers.? Saved the documents on my shack server for future reference.? And thanks for the compliments.? Update : Yesterday evening I printed a few more and found out that the margins where to small to make a good and easy fit (filament 3D printing isn't exact science). So today I will be looking at where I have to modify the design to make it fit better.? -- 73 Lex PH2LB?
Lex PH2LB All Messages By This Member #163 I got my self a rol of red PLA (it's a little bit lighter then the red color of the original knob, but it will do) and printed me a few power switch knobs.? ? The light switch knob is also a little lighter because the darker grey I have is almost the same color as the front panel. The final result and I'm quite happy with it.? For who is interested, I have added this story (and more) to my website :?? -- 73 Lex PH2LB?
