Thank you. Yes, they're great machines ! Wish I had got one years ago. So accurate, I can get text down to .5mm !! I see you are doing a steam engine, I did small plate for a Stuart Turner No4 I made which came out nice :-)
@@bonesshed. yes I seem to have been making a Stothert and Pitt engine for years!!! I engraved a name plate on my CNC mill but now I need to make another one with this years finished date (or next years date!!)
Sorry if I missed it but I didn't catch showing you making the hands. How do you make them? I imagine that to be quite complicated due to the bore on the hands that will go on the center wheel
the outer shape is easy enough. But youre right, making the centre point to fit a shaft is tricky. Im just in the process of doing a couple of experiments so will post up if successful !
Great video. Enjoyed all the input. The heatsink clamp sparks ideas. I'm in the process of producing dials with my laser as well. Very exciting. I've been successfully engraving 0,4mm spring stainless steel. (for bare metall finishes. Need to move to brass as well for painted dials like yours so it was great to watch your video. BTW! Which glue would you recommend for gluing brass or other metals? Sending greetings from Stuttgart Germany
Thank you :-) Yes, I believe that good clamping for thin metal is a must, along with the heat sink I dont get any warping. For gluing I have used nothing more exotic than super glue ! Once the dial is spray lacquered that also seals everything in. sorry for the late reply.
Thanks mate. Its called a DB30 from a company in Yorkshire called custom laser. I paid 6k for mine. you could probably get a similar spec machine cheaper on ebay, etc but I wanted back up should I need it.
Good question. I havent got that far yet. Lol. I havent really progressed from here TBH.. I have a couple of cases to try but I just havent had the time of late to do much ! I will likely make a jig to drop the feet in place while I solder them.
@@djbenefit I have seen hands before with a small slit from inside the hole to the outside. So the trick is to get the hole size a tadge smaller than the shaft its going on. The slight 'spring' action holding the hands in place. Should be a lot easier than soldering tubes on ?
To be honest I haven't got that far ! 😁 The traditional method is to solder tubes but I believe you could run a cut line from the hole to the outer edge and close the hole a tad. This would act as a spring. Maybe 😆
Hi there! Thank you so much for this video. It's awesome!! Do you think I could do this with a 30w fiber laser from aliexpress? Let's say Hauser or cloudray?
Hi, Thank you. I dont see why not, if its 30W and uses the same EzCad software I see no reason it shouldn't. Hop onto the lasereverything channel, some great info on there.
Amazing technique! It was a bit frightening to see you moving your hands near the dial as the laser was cutting. Be careful! And wear goggles - laser light can reflect off metal parts and end up damaging your eyes!
So this is not entirely accurate. The laser is about harmless above the focal point. If this material reflected the laser light then it would not be able to engrave. This is why fiber lasers are used for metal. The 1065nm wave length is easily absorbed by metal. Yes you should rear goggles but the risk of reflections very unlikely
Just as a note for your knowledge. The laser cannot harm skin. That’s why they use lasers to remove tattoos. It is something to do with the moisture within the ‘haute’ (did I guess that correct with my bits of German language?). Good luck. P.s. wear goggles though, lasers will blind you!!!
