I've followed this discussion with interest as I have been trying to find similar small pumps for my mini-EDM machine with a similar fluid flow requirement. Background - I originally began operating this machine with water, but found tool wear was too great. My pumps, lines, and filter (home water filter), worked fine with water, but in trying to convert to SinkSyn commercial EDM fluid (similar to charcoal lighter fluid or solvent), the small 12V pumps failed when rubber parts within became swollen and mishapend. So I tried some Chinese G928 $40 peristaltic pumps from ebay https://www.ebay.com/itm/195754033059 with silicone rubber tubing. With air, the vacuum was great and output pressure 25 - 30 PSI, but the silicone rubber tubing ends began to swell at 10 PSI and are quite bulged at 25. I bought some similar-sized (1/4" ID, 3/8" OD) Tygon tubing rated for fuel, but as it is stiffer, vacuum and pressure levels were less, and the 12V supply current (particularly starting current) was substantially increased. In addition, the peristaltic pumps are noisy. I have been searching for alternative small pumps that can safely handle oils and would appreciate learning of any discoveries by others. My flow requirements are about one-cup/minute at a pressure of 20 to 30 psi. I need both a supply pump and second pump for vacuum service, to collect fluid from under the workpiece. Ideally the same type could be used. Bruce, KG6OJI

I finally have a motorized Z axis. It has only taken me 7 - 8 years. I wanted to implement a X axis to the Atomic leadscrew so I figured I had best write a program. To help me write the program, since I am not a programmer I went on the accellstepper forum and asked for help. Here is lathe in operation. The noise might be a bit much so turn the volume down. hthttps://photos.app.goo.gl/dP9QguUrgAEG3Zup8tps://photos.app.goo.gl/dP9QguUrgAEG3Zup8 I know that is not very impressive but for me it is a big accomplishment. If any one would like to get started with just a motorized Z leadscrew let me know I will share my file. Now I am trying to implement a direct drive on my spindle.

This is for the "animal" , a music freak. I wrote this music called "Sleepy Time Train Blues when I was stuck in the Chicago main train station waiting for the tracks to be cleared of snow. I was trying to get back to Santa Barbara CA. I should've stuck to my original plan and waited for the snow to be cleared at O Hare, a bit like Trains Planes and automobiles move. For whatever reasons, the US travel infrastructure I found was a disaster for the 25 years I travelled internally. It was much easier to travel to Japan than to get to San Francisco from Santa Barbara. Oh well, things have possibly improved since I left the states more than 18 years ago. Moving to Spain, I am still involved with music, be it teaching, repairing and composition.and some Murcia jazz bands. Played extensively when time permitted with the Ulyses Dixiland Jazz band from the Irish pub, called The James Joyce in downtown Santa Barbara. My group called the Geckos (lizards) recorded this with many more pieces of music. Me tenor sax, Paul RIP god bless Piano, Nic guitar. after I moved to Spain. The theme of this recorded track was at the time. I was cold, bored, waiting for at least an engine running, so it starts off with an old steam train leaving the platform, picking up speed, crossing the points, animal alert, get off the track, steam whistle FOG HORN etc etc. Anyway, "animal" and others please enjoy it I hope, and back to it, duty calls. Again that's it folks. John

I know this is semi off topic even though some instrument repair was mentioned earlier along with John talking about some of his repair tools . I stumbled on this guy Wes Lee a few years back somehow & watched a couple of his videos & ended up subscribing to his channel I enjoy learning about new things daily & watching a true craftsman is a plus . If your interested in seeing this here's a link to the channel . I watched him repair some things that I thought were a complete loss . Guy's like this are hero's to the kid in band that dropped his sax or trumpet . https://www.youtube.com/watch?v=iOX5ggovDqU&ab_channel=WesLeeMusicRepair if not there's always the delete key . animal

Hi guys. Without a quick and easy screw keypad enter selection using my RELS. making new instrument key pivot screws on a lathe using standard gear changing, even if possible would be a real nightmare and RELS taper turning on a compound slide ( I removed mine), Gr!!!!!!!!!!!!!!! , again I use the RELS. If I need to cut a new pitch not already in RELS memory, I just add onto the spread sheet, alter the Tables.h and get the job done. The attached photos are just some of the key pivot screws that the instrument manufacturers use. Imperial, Japanese metric, std ISO metric and the odd ball French pitches, LOL Of course all of the above info is not necessary if you only intend to repair grandads broken flymo grass cutter. LOL I am a serious daily RELS user. Cheers John

Hello everyone, I have been busy with other projects outside my shop. Finally I have started working on my lathe hopefully heading to using AtomicELS. I have always wanted to add the X axis to AtomicELS so I figured I had best to sharpen my very limited programing skills. I thought I'd start with Accelstepper Forum I had been lurking on the forum for a couple of years so thought I'd see what they might offer for a stepper program to control the Z stepper. This was just to move the Z axis back and forth. Jim Larson made up a program using accelstepper that was above and beyond what I had initially envisioned. I now call this my automated leadscrew program. I have used a Consew 3/4 hp Brushless DC motor for the past 5 years. The motor started acting strange so I bought a new one. The new motor had a different mount so I had to make up a new mount. The new mount is so clean one would think I actually knew what I am doing. I tested the motor and everything seems to work. It is interesting now the motor speed indication should be my spindle speed. I used to have a optical speedometer I'll see if I can find it. So now I need to get my Z axis motor wired and test with my automated leadscew program. Next I need to get a encoder or pulse generator to send spindle speed to AtomicELS. This will be next on the list. This forum is going to get a lot busier as I tend to ask a lot of questions. This forum in the past has been busy with lots of questions and answers and observations which I have really enjoyed, so Thank You, to all of the previous posters. And also thanks to those who helped sponsor our subscription to groups.io for the forum. The subscription is coming due soon so if anyone would like to help me pay for the subscription you can use rhulslander (at) gmail.com on PayPal. Thank you for the help.
