Axminster/Seig C0 Lathe Swich Repair/Modification.

This is the second switch failure so I modified the design with an easily replacable micro switch.

Nice repair. Excellent use of a 3D printer, the micro switch should last a lot longer than the original did. Thanks for sharing.

Nice job Thanks for sharing

Nice fix. I myself would just buy another potentiometer with integrated switch, but that's me.

[@mattbrown9484]

Might just be that he didnt want to wait that long.

[@bw6378]

I probably would have just put a seperate switch in permanent so that the speed setting would stay the same. Still a fun little mod though. Thanks for the video.

[@myfordboy]

@@bw6378 That would not work. The electronic control means you have to return the control to zero or a fault light comes on and the motor won't start.

Thumbs 👍 so variable part was OK just the switch on/off faulty.

[@myfordboy]

@@johnwynne-qx6br That's right.

[@RustyInventions-wz6ir]

Very nice work sir

[@jrehtil1494]

Great job

[@ysgolgerlan]

Thanks for the video, nice job. 👍

[@RetroSteamTech]

Those switched potentiometers are readily available but your solution will probably last a lot longer than a replacement given that the original failed. Nice job 👍👍 Cheers, Alan.

[@myfordboy]

This was the second pot that failed. I don't think the switch in a regular one is up to the job.

[@RetroSteamTech]

@@myfordboy The switches on those can be pretty feeble, the microswitch should be a lot better.

[@ptonpc]

It works!

[@ego73]

"What?? 'Buy it off the shelf'?! Hah! I'll bloody build one right n proper, you!" Seriously though, fuckin' good job!

Hey Myfordboy, Do you rememeber a rude jock telling you that casting what amounted to an aluminum shaft was an utter waste of time and to get a 3D Printer and print your molds ? :) Hope your enjoyin the 3D printer ! :D Ive got myself a DW Mk1 recently set up next to my 'Creame' Axminster C0. The DW is also Creame so they sorta go well together. I never did get around to doing any casting though ! :/ Was taken away to work for the RN in a Grunt/Dogsbody capacity. Sounds about right eh ! :) Maybe in time I will make some castings. Hope you well and enjoyin your projects. I made a micro boring bar holder today on the DW and C0 for the C0. It takes 4mm HSS Shank./Drillbits .

I would suspect either no relay between that switch and the motor, which over works the switch or if a relay is used there is no diode on the relay to quench the back EMF with the flywheel effect of the chuck slowing down. Which will also over load the switch. If no relay is fitted I would fit one with a diode or the microswitch won't last long either.

[@myfordboy]

The switch does not carry the motor load.

[@robstirling3411]

Was that switch operating the motor via a relay? They were never made to operate more than an amp or two.

[@myfordboy]

@@robstirling3411 I don't think it carries much current. The wires go into a PCB that controls the motor speed. It failed mechanically.

[@bobweiram6321]

Those switches are a few bucks on Amazon.

[@myfordboy]

The original ones? They are not up to the job. 2 have failed on me, hence the mod.

[@bobweiram6321]

@@myfordboy No. The branded ones are more expensive, but there are better ones.

[@myfordboy]

​@@bobweiram6321I replaced the original when it failed with a genuine Sieg one and this failed also.

[@robstirling3411]

They don't make them like they used to!

beats me how you get your big fat fingers into such tight tiny spaces, and that you can actually see what's going on, well done. excellent helpful video thanks
