Delta 46-715 Lathe Repower #4: Delta 46-715 Lathe Repower #4: Getting Pullies running True and Accurate

01-16-2017 08:56 PM by Pete_LJ | 1 comment »

Sorry for taking so long to get back to you on this project. Honestly, we had a renovation on the house going on which required all my attention. Let me recap a little regarding where I was back at my last entry, hurdles, solutions and new issues. In my last entry, I had lined up the belt and pulleys by eye. Additionally, I had a custom keyway made by the local machinist whereby the 46-715’s 3mm key slot was able to mate to the keyway 5/16” (equivalent to 8mm) slot of the M...

Delta 46-715 Lathe Repower #3: Part 3 - Fitting Belt and Determining Linear Location of Driven Pulley

06-13-2016 02:36 PM by Pete_LJ | 3 comments »

06132016 It was a busy weekend and I did not get a lot done on this project. But I did make some progress. I was able to fit the motor to the swivel shaft and box while mounted to the lathe. I need to fix the linear position left to right for the hub and driven pulley. I also need to get the tensioner fabricated and adjusted. I have some pics for you with the motor and shaft in rough position and also the driven pulley/hub. The bungee cord (pictured below) is just being used tempora...

Delta 46-715 Lathe Repower #2: Fitting the Driven Pulley and Fabbing Support for Motor and Swivel Bar

06-06-2016 07:15 PM by Pete_LJ | 1 comment »

06062016 I got the rough version of the box built and attached to the back of the lathe. In addition, I decided to go with the first alternative on mounting the driven pulley (namely, Maska Pulley Hub with three fasteners to be attached through holes that need to be drilled accurately in pulley). I created two wooden plugs using two hole saws: i.) 1 7/8”, and ii.) 1 1/8”. Neither hole saw created the perfect size plug. So I wrapped electrical tape around the 1 7/8” plug (actually 1.579” fo...

Delta 46-715 Lathe Refurbish Project #8: It's done!!! Ready to start turning!!!

01-27-2015 01:46 AM by Sawdustonmyshoulder | 6 comments »

I got it done. The only thing I might do is paint the additional parts on the motor cover battleship gray. The scale was made with a clear self-adhesive shipping label. I got out my tachometer and made a test run and marked the speeds on the lathe. I then took a photo of this pencil scale head-on and laid out on my computer the scale. I made a printout and went to OfficeMax and they copied it on the shipping label for 68 cents. Can’t beat that! I put the switch for the DC ...

Delta 46-715 Lathe Refurbish Project #7: Controls Done and Turning Zinc!!

01-20-2015 04:02 AM by Sawdustonmyshoulder | 14 comments »

The control box is done and mounted. I found a few things out the hard way. One was you don’t ground the motor controller. Man, the flash and the smoke! Well, that was a motor controller down the drain. Luckily, I had a spare. Upon a little research, DON’T GROUND THE MOTOR CONTROLLER’S HEAT SINK. The box I bought was aluminum, so I had to isolate the motor controller from the box. Nylon screws, washers and bolts was the solution to the grounding issue. I did ground the alumi...

Delta 46-715 Lathe Refurbish Project #6: Fire that puppy up for a test run

01-11-2015 03:36 AM by Sawdustonmyshoulder | 6 comments »

After mounting the motor and installing a temporary belt, I plugged in the controls and tested the lathe. It runs very well and smooth. I think it will run even smoother with a segmented v-belt. I’ll run to the auto part store tomorrow afternoon and pick one up. I hope they have one to fit. Here is a video of the lathe running. The maximum speed of the lathe is going to be 2865 RPMs. Not quite fast enough for turning pens, in my opinion, but fast enough for table legs and spindles. I...

Delta 46-715 Lathe Refurbish Project #5: Motor Mount and Indexing Pulley

01-11-2015 01:32 AM by Sawdustonmyshoulder | 1 comment »

Today was a good day. Received the indexing pulley from Fred Borden in the mail. Thanks, Fred. Installed it on the lathe and it works great. May need to be turned and trued up a bit. It must have had a hard life. No problem to do it. A friend needed a treadmill to be disposed of and wouldn’t you know it, it had a motor mount that I could use. After cutting the motor mount off the frame with a grinder, I put it on the motor and Shazam… it works perfect. I need to get a belt f...

Delta 46-715 Lathe Refurbish Project #3: A Couple of Pulleys

01-02-2015 10:20 PM by Sawdustonmyshoulder | 4 comments »

I bought the pulleys this morning and mounted the motor pulley on the flywheel only to find out it wobbled. BUMMER! The stub was about .005 too small. Well, I got another flywheel and reground the stub paying attention to stop grinding before I reached 3/4” and finish with a file. After drilling and tapping for the set screw, I mounted the 2-1/2” pulley and it runs sooooooo smooooooth!! Now, on to the driven pulley. I bought a 24mm split tapered bushing and a 5-1/2” p...

Delta 46-715 Lathe Refurbish Project #1: Getting the Lathe Home and Mapping the Process

12-31-2014 03:38 AM by Sawdustonmyshoulder | 7 comments »

The Lathe Here is the lathe. I bought it on Craigslist and got what I feel was a good deal. I went to Nashville and picked it up on Saturday. My plans are to replace the AC motor with a DC motor and make the lathe variable speed electronically. Empty Head This lathe has no drive pulleys. The Reeves drive broke and all the parts were trashed. So the headstock is empty except for the spindle and the indexing pin. Motor The AC motor is good so I will put it on eBay and...
