For me it was stumbling onto a book at the library called how to build a lathe from scrap by Dave Gingery.  All I had was a tiny Unimat DB-200 and it was before the low cost 7x20 lathes started showing up.  So I built his gas fired foundry and added a small computer for electronic ignition and fan speed control. About 10 years ago when we switched from an oil fired home heating furnace to natural gas I reconfigured the Gingery Foundry to also run on natural gas.  It's like the table saw now.  Switch it on and use it.

 

To build the furnace I had to build his power hacksaw and slip roll.  An acquaintance with a larger lathe bored a draw bar hole through the middle of my Sears Craftsman 16" drill press spindle.  An XY vise made it possible to do simple milling with MT-3 based tools held now firmly held in the spindle.

 

The end result was here:

http://www.autoartisans.com/gingery/Gingery_ELS.jpg

And since I couldn't make gears yet I designed and built the Electronic Lead Screw controller.

 

Now I have a South Bend Heavy 10L.  Haven't used the gears on it for a number of years.  The tumble gear is in neutral and the gear select set in the dis-engaged position.  Spline ribbed belt drive so the whole thing is very quiet with a VFD on the motor. Haven't gotten around to powering the X axis yet.  The ELS works fine with only the carriage controlled. Prompts for cross slide motion.

 

Casting is a very primal hobby.  However the real challenge and work is in the pattern making.

I am having a heck of a time trying to get the nut off of the cross slide handle. Does anyone have a trick? I made a spanner tool, and promptly broke it. I tried a small torch and some penetrating oil, to no effect. Tried a brass drift to try spinning it out. All I did was bugger up the brass drift. My last option is to put it in my other lathe and cut it out. That is not totally out of the question. Nor is making a new screw for the compound EXCEPT that currently my Sheldon 11" is out of commission. I am trying to get everything on the SB 16/24 replaced and painted, at least on the top end so I can use it.

Re: 9A motor/drum switch Mounting

Actually an auto oiler could be part of the enhancement program. Here's a photo of the R&D platform. Instead of an 8 bit PIC18F I'm using a 32 bit PIC32. The one on the board isn't the actual processor since it doesn't have a QEI module for quadrature encoders but the software all ported over nicely with only a week or so of work. Just a couple of tiny bugs to deal with yet.

This test setup plugs in place of the PIC18F processor. The final add on board will have additional connectors and also plug into the header to add additional I/O to the DB-25. And hopefully this version will support quadrature encoders and provide much better closed loop speed and position control.

I'm in the middle of my mill to CNC conversion and then I'll go back to the Lathe Conversion. Time to add a motor to the back end of the 10L cross slide just past the taper attachment. I've already changed the Charge Pump output to be PWM to drive this little module
https://www.aliexpress.com/item/33021792064.html
which will connect to my GS-1 VFD. And then I can do constant SFM while facing.

Guys, do you mind sticking with a standard font color like black on white or white on black?

Cutsey fonts on your home PC are virtually impossible to read on some mobile platforms.

For example, i was unable to read the prior message until i entered a building. Outdoors, the font washed out enough that i could not read the message even with my glasses on.

Typos are courtesy of autocorrect.

Its just a stock "ish" Gen 1 Ender 3, according to Creality they are currently $209 (plus shipping I guess) to you US folks, it really a great machine as long as you make yourself aware of its limitations and can learn how to maintain, adjust and recognise print issues, it is certainly not a take it out of the box and turn it on type machine.

They also make the Ender 5 which I'm told is around the same print quality wise but easier to assemble/square up.

If you know your way around CAD its fun, I've made endless custom parts/brackets/tools, my 9a alone has a:
-3d printed carriage stop
-dial gauge holder (both carriage and QCTP),
-carriage lock handle,
-spindle thread protector,
-Threading dial (an accurate copy of the original) 
-and a semi working (of questionable quality) adjustable carriage stop

As you can tell, I really like 3D printing.

Re: 9A motor/drum switch Mounting

Another example of where 3D printing can be used as a tool.  It was an experiment that worked surprisingly well.

 

I needed a pulley for this 1.8kW Bergerda AC Servo so I cast one and bored to 19mm shaft diameter.

http://www.autoartisans.com/mill/CastPulleyBlank.jpg

I needed a keyed arbour for it.

http://www.autoartisans.com/mill/PulleyArborKeyway.jpg

To broach the keyway one needs the guide that has an OD of 19mm and a slot the width of the broach so I 3D printed that.

http://www.autoartisans.com/mill/PulleyBroachBushing.jpg

And it worked quite well.

Now it was possible to finish turning the pulley concentric to the bore.

And the end result came out very well.

John,

Nice work!  I'm going to see if I can do a little interweb surfing this weekend and elevate myself from the bottom of the learning curve.

Thanks,

For my 4th axis harmonic drive I made the pattern for green sand casting the mount.

printed in 4 pieces and glued together and cleaned up with body filler and primer/paint.

And here's the 4 pieces glued but no bondo and one of the quarters of the as machined version.

Hi George,

Its just a stock "ish" Gen 1 Ender 3, according to Creality they are currently $209 (plus shipping I guess) to you US folks, it really a great machine as long as you make yourself aware of its limitations and can learn how to maintain, adjust and recognise print issues, it is certainly not a take it out of the box and turn it on type machine.

https://www.creality3dofficial.com/products/official-creality-ender-3-3d-printer?variant=31558724550729

They also make the Ender 5 which I'm told is around the same print quality wise but easier to assemble/square up.

If you know your way around CAD its fun, I've made endless custom parts/brackets/tools, my 9a alone has a:
-3d printed carriage stop
-dial gauge holder (both carriage and QCTP),
-carriage lock handle,
-spindle thread protector,
-Threading dial (an accurate copy of the original) 
-and a semi working (of questionable quality) adjustable carriage stop

As you can tell, I really like 3D printing.
