  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

King 1440 Lathe Speed plate

If the motor is not original, is it the same speed? (so the speed table is correct…)
And/or, is it 3 phase (for use with VFD)?
 
No reason not to go with a 3-phase and a VFD. The second photo in post #14 is the speed chart for my mill. 12-speed belt system with a very conservative VFD configuration. Allows me to use the VFD to adjust speed, say when step drilling steel using a range of drills, without having to change belt positions. But still have the option to run a big cutter with the belts set for a low speed range while getting maximum HP from the motor at full speed.

VFD is set up to restrict output between 30 Hz and 90 Hz. Gives a 3:1 range with the nominal 1725 rpm motor adjustable between roughly 850 and 2500 motor shaft rpm. Gives a nice set of speed ranges while still providing the pure hardware grunt torque achieved by mechanical speed reduction. Best of both worlds.

As for the graphics, I ain’t Van Gogh. Simple line graphics are doable, if I can draw it in 2-d CAD I can engrave it.

Makes sense. With VFD and original graphics I at last have an idea what the speed is, even if I do adjust it a bit with the VFD.

Just an update:

I'm trying to source a couple of parts I need from King Canada as I go forward with the rebuild. One is the bevel gear for the garage feed, and the other is the shaft for the cross slide. I can make the shaft for the cross slide if needed (acme threads, and I think left hand thread will be fun) but the gear is another matter. My local dealer is no assistance, is I will call King Canada after the long weekend and see if they can help.

I would like to send you the plates from the machine to get etched. I am currently in the Maritimes, and will be for a month, and then arriving home to a busy summer schedule. I hope it's OK if I arrange something either late summer or early fall since things (I hope) will settle down.

Really do appreciate the offer!
 
Kind of depends on how fancy you want to get. Engraved aluminum is relatively easy - once I know the overall size I mock it up in CAD and select font sizes that scale up roughly to the original.

New from scratch. My fonts won’t be a perfect match, and my belt diagrams will be line art so might not be exactly the same. But, engraved on 1/16” aluminum with a 0.010” depth of cut they will last forever. I usually fill in the engravings with black nail polish or acrylic paint. When it fades or gets scuffed up a few minutes with acetone and a Scotchbrite pad and all the paint is gone, ready for a new coat.

Other option is engraving a photo image of the original plate, but really fiddly because I would need to do all the touchups and squaring up of the image before engraving. End result will not be as crisp as new from scratch, because it’s difficult to get all the text and lines straight.

Third option is laser engraved ABS, can get razor-sharp lines but it’s not as robust as the engraved aluminum. White lines on a black background.

A couple of samples. And it’s not 0.050 depth of cut, dyslexia strikes again!

That last one looks superb, Crisp and clear. Oh boy !
