Re: Gear Reduction transmission for the HF44142 lathe

Hi! Torch, As I remember on the units I used in the past, the max useable torqe was at (Full Amp Rating) and at (Rated Speed of the motor) and on the V.F.D.'s as you lowered the frequency you had to derate the load or torqe otherwise you would trip the soft limits in the V.F.D. You did not gain tor...

Re: Gear Reduction transmission for the HF44142 lathe

Hi Torch.. The problem I have found when I used V.V.D.'s V.F.D.'s and D.C. controller's was that even after you spend all the money for new motors and controller's and then setup and tweaks, you end up with one small window of speed with max torqe. With belts and or gears I can go 50% bigger on the...

Re: Gear Reduction transmission for the HF44142 lathe

Hi Torch, You are correct about the speed of a pipe cutter.. :D That's about how fast our Rigid unit was. I want to beable to shift in increments of about 10 RPM steps from say 20 RPM up Thru 160 RPM. 160 is the low end on a HF44142. This will give me the freedom to adjust speed when my crazy littl...

Re: Gear Reduction transmission for the HF44142 lathe

Hello. Has anybody ever made a transmission to allow slowing the lathe speed down to about 20 to 40 RPM or so. I Guess what I'm thinking of is for it to act like a south bend back gear. (Slow with lots of torqe) Any idea's would be great. Thank You. Ken. What diameter threads are you planning? 30rp...

I have probably spent at least $150/month on 'tooling' Mostly from EBAY, Enco, MSC, Shars, etc. One thing leads to another, and another , and another.My biggest single expense was a 3 axis DRO for the tabletop mill. Was a challenge to install it correctly too (not used to .003 tolerances overlong d...

I have notified Marty, who must address the issue. He is absent, so it may take a couple days. I thank you for your patience, and apologize for any inconvenience that may result. We'll get things straightened out, folks. :wink: Harold And they did. Thanks to Marty and Harold's efforts, I'm back. I ...

Ok, something weird is going on here. My website is xxxxxx.org, not xxxxxx.net. I can log into my profile, and see that the e-mail address is set to a xxxxxx.net address, but I can't change it -- it refuses to accept my password (though it will let me post???) I think we need the services of a moder...

Dear Torch,

You didn't use your own e-mail address when you signed up to this forum. Instead you used mine. I tried removing my e-mail address from the settings on this forum, but I wasn't allowed to.

Please change the e-mail address on this forum.

Yet another newbie

I suppose I should introduce myself. I'm a former pipefitter with lots of experience using dedicated machines for threading and grooving. I'm not a great welder, but usually manage to stick two pieces of metal together and coupled with judicious use of a grinder as needed, can even make it pass a pr...
