He's talking about the older stuff that was laid out on a 2.54mm (1/10") grid. DIP packages are that size, as are most headers. Of course there are 1.27mm headers (1/20") as well. Most newer

Not to be argumentative, but .156 in (common on pin headers) is 4 mm. David Robertson. ________________________________ Sent: Monday, May 6, 2024 2:56 PM To: [email protected]

Decimal inches at that. Tony Sent: Tuesday, 7 May 2024 5:57 AM To: [email protected] Subject: Re: [7x12MiniLathe] Drill a Hole Most do not know most holes on pc board are layout

Right, and how is slapping a 100°C cut-off switch on the casing going to help you? If your casing hits 80°C you are probably already screwed. What part of “the enamel on the coil will start to

Most do not know most holes on pc board are layout in inch. Dave

The PCB drills are these: https://www.aliexpress.com/item/1000004406073.html, or carbide https://www.aliexpress.com/item/4000905456721.html. 3mm & under are cheap because they use these by the

The best wat is to figure out thd outside temperature is when coil is at 105°C. After researching the problem it was between 15°C and 20°C different. Basically thd outside temperature of motor is

Yes, but you need to put your sensor on the coils. Which are on the armature for a brushed motor. Which are spinning around at high speed. Can you see the problem? Tony

I tested the gauge with boiling water witch is 100°C. It was on the mark. Note: Use distilled water only If over 500 foot above some correction is need ti temperature. Dave

When someone says the motor is at 105 C. My question is “How did you calibrate the sensor?” Most motors will start to be damaged at 85 C and 105 C is about the limit of what they can take. I

With temperature gauge I can see I needs to run at full speed It low cost cost item to save from buying a $160.00 motor . 1) I first was think of using a time delay fuse.? The remember thd low speed

Thanks Johannes animal

Hi Mike I have not found my shop yet, it is here somewhere. Home depot is ok, however not for the most I am doing. Mostly I get my stuff from China. Johannes Lavoll. Mexico

The Guage is from Walmart it cost under $14.00 It is also on Amazon for about same price. My wife has free shipping on Walmart. Dave

That is a hot motor Thank you for photo mine did have a label. 120°C is 248°F Dave

????? A bit off topic but Johanes I'm wondering if you have supply houses where you can get drills & lathe bits in your p[art of the country . I have one that @ 50 miles from me in Reno & another

I am looking for temperature be for smoke. I can only go by what in print. I hope motor stays cool. The? ambient used is either 40°C or 45°C? plus 60°C for motor. It all for longer

Here's a pic of the motor that goes on my mini lathe. Looks like it's rated class E, which is 120 C per a wikipedia article. Stan

You're drilling lots of these holes, so it would waste too much time to use a spotting drill, mill flats on the rod, and so on. Instead I would use a guide block, but different than the one in your

Those are not operating temperatures, they are MAXIMUM temperatures. You want to be as far away from them as possible. If your casing is 80 degrees then your armature is far hotter than that.
