    Clough42 ELS upgrade for Weiss WBL250F Lathe

    I've had it working for several months with the servo motor hanging out the front, with pulley cover off. The last couple of days I spend relocating the servo motor so that I can put the belt cover back on. I was able install the ELS with minimal modification to the lathe. Drill and tap two...

    Weiss VM25 Z axis power feed.

    I ran a quick test to measure the output RPM of the wiper motor gearbox at low and high speed from 6VDC to 13VDC. No Load slow speed (green wire) = 39 RPM @ 12VDC, 1.86A. Speed is approx. 3.25 RPM/V No Load high speed (yellow wire) = 51 RPM @ 12VDC, 2.75A. Speed is approx. 4.2 RPM/V. I'm...

    Weiss VM25 Z axis power feed.

    I finally got tired of cranking the the Z axis up and down. So I decided to have a go at adding a power feed. There are plenty of good ideas out there for me to copy and I decided to use a wiper motor to power the axis via a timing belt. I purchased a wiper motor from Amazon, $33.49 free...

    Faceplate for Weiss WBL250F, 8.66" (200mm)

    My Weiss WBL250F lathe didn't include a faceplate, so I've been looking for one that would be an exact fit or could be made fit with minor modifications and or an adapter. The Weiss WBL250F spindle nose pilot is 52mm OD, with 3ea clearance holes on 75mm PCD for 8mm studs. Just by chance I was...

    Tailstock DRO for Weiss WBL250F

    I added a DRO to the tailstock of my lathe primarily because I had trouble reading the graduations on the ram. Consists of 3ea 3D printed parts and some M3 SHCS. I posted the files on thingiverse.com. https://www.thingiverse.com/thing:6159891 Seems to do the trick. Just installed it last...

    Arduino Rotary Table

    Bruce, The table I purchased has a ratio of 36:1. I calculated that with the driver set at 1/2 step, the number of steps required for 360 degrees would be 36*3*400=43,200 As a quick test I changed the driver to full step so that 360 degrees would be 36*3*200=21,600 steps. I didn't consider...

    Arduino Rotary Table

    I considered changing the data type to long, but because of the 3:1 belt drive reduction, the table moved very slowly. It was an easy way to speed things up. I always install a pin header and use shorting jumpers for enable, Mode0, 1 and 2. So I just pulled the jumper off M0. Thanks for the...

    Arduino Rotary Table

    Bruce, The electronics worked perfectly, first try. Using default settings for gear ratio. Thank you. I wanted to retain the the handwheel so I 3D printed a bracket and used a 2GT belt drive with a 3:1 ratio. When I update the code to include the added 3:1 ratio. The code stopped working...

    Arduino Rotary Table

    Thanks. That's good to know. I do have the system working with an old NEMA 17 stepper I had lying around. It's 200 steps per 360 degrees. I'll put a pointer on the stepper shaft and use my old degree wheel to check it out. I was planning on making the degree wheel the face of a clock for my...

    Arduino Rotary Table

    I have finished the electrical portion of this tool and I'm now ready to buy a 4" rotary table. Such as: https://www.amazon.com/Inches-Regular-Rotary-Milling-Machines/dp/B099KMBKTH/ref=sr_1_10?crid=3M7PEN1GQT71X&keywords=rotary+table&qid=1682803738&sprefix=rotary%2520table%2Caps%2C150&sr=8-10...

    New mill and lathe.

    Sorry for the delayed response. I haven't been checking messages. No significant issues to report for the mill or lathe. Both machines probably have about 4-5 hours of use. I fixed an oil leak on the lathe on the headstock oil reservoir. It was just insufficient sealant on the mating surfaces...

    Mill light.

    I saw a few posts about this topic. Another good idea for a cost effective light. This is the one I installed. Qasim 1 Pair 90MM 66SMD COB LED for Angel Eyes Halo Ring Headlight Fog Housing Lamp with Cover White 12V 24V DC https://a.co/d/7v9fNuS

    Machinist vise repair

    I broke my screwless machinist vise half way through a project. It could be that I just overtightened it. The part appears to be sintered or cast? The dowel hole is a clearance and they used a grub screw to hold it in place. I fired up my little Taig lathe and made a replacement using some...

    New mill and lathe.

    Agreed. Great videos. She has the PM version. They are almost identical.

    New mill and lathe.

    I haven't taken the chucks apart yet, but it's on my to do list. Definitely a good suggestion. I haven't leveled the bed yet. I still need to decide on the final location for both machines. It will be interesting to see how it works out. It's something that I haven't done before. The lathes...

    New mill and lathe.

    Hi Craig, I took apart the tailstock, toolpost and compound and they were fairly clean. I will probably disassemble more and lube etc. I'm waiting for the material to arrive to make the 4 jaw chuck adapter. The chuck is attached with 3ea 8mm studs. The registration pilot is 52mm. I like the...

    New mill and lathe.

    Craig, I originally planned on getting both machines from Precision Matthews, but they were out of stock. I live in Arizona and the shipping would have been $400. I purchased both machines from Toolots. They are in California and shipping was free. I also had a 5% off coupon. I looked at...

    New mill and lathe.

    My Taig II is a great little lathe and I plan on keeping it for very small parts. For larger projects I added a bigger lathe and a mill. I just finished building the benches. I haven't used them yet, but they spin up OK and the DROs work very well. It took me a very long time to decide what...
