    Th/qc54 Motor Controller Problem & Question

    I finally got my TH/QC54 lathe dc motor conversion done, and up and running! I did some practice turning on a scrap piece and all seemed to work fine. Took into making my first actual part, a small shaft .390 diameter CD steel. I made a number of passes on the part, when the motor speed...

    Looking For A Volunteer With A 7x10 Or 7x12 Harbor Freight Lathe

    I need to "borrow" it for 2 weeks before summer heats up. You must live in my local area. Within 20 miles of Anadarko, OK or be willing to drop it off for 2 weeks. What you will receive is a new tachometer after I am done. I don't have a 7xXX machine, but I have requests for a tach to fit...

    Why Isn't The Feed On Manual Lathes Servo Controlled?

    I realize that quality servo motors and a synchronous control loop are not inexpensive but neither are they expensive. Why haven't they replaced the feed gearing on manual lathes? I would think it would greatly increase the range of threads that could be cut and save on the time required for...

    Pm-1340gt Vs Pm-1440gt

    I have been researching my first, possibly last, lathe purchase for a couple of months. I thought I had settled on a 1340GT and contacted Matt @ QMT last week. It was a fantastic pre-sales experience and Matt pointed me at this forum to research VFD conversion options. This led to the...

    Boring Pre-game

    I made my first serious attempt at boring last week on a supremely under-powered and insufficiently rigid lathe. It took ~4 hours (yes, hours of listening to a belt slipping) to bore out a ~1.75" ID / 1" depth in 1018 (and I over ran my tolerance, so I get to make it again...). I started the...

    The "why" Of Lathe Tool Height

    I started learning to use a manual lathe towards the end of the last year and I have seen conflicting advise for the proper height of lathe tools. Often, I see a forum post with advise along the lines of "at center or slightly above" but I have also seen the opposite of "at center or slightly...

    What Lathe To Keep?

    I am a retired carpenter and fairly new to machine work, (about 5 years). I have a classing 5914 lathe that I absolutely love and would never part with, but have got into buying small lathes, cleaning/repairing them, then selling them for a small profit to support my machining habit. The problem...

    When Sensitivity Means Precision

    Over the past few years I have developed a number of Electronic Edge Finders (EEFs) to be used on both my lathe and mill. All of them tried to have a simple "idiot light" on them that indicated when the cutter (or equivalent) touched a conductive reference surface clamped to the rest of the...

    [Documentation] Cincinnati Traytop Hydra-shift Restoration

    I purchased a 10x36 Cincinnati Hydra-shift that is in decent mechanical condition, but is about as ugly as they come. I'm guessing that it was in a shop in the 1980s when things got slow and someone was told to paint the lathe. That person didn't clean the lathe first, so that is why I have...

    Scraping Question

    I recently acquired an Atlas 10 with a 54" bed. It has wear along the first foot or so of the ways. In order to scrape the whole bed back together would I require a straightedge that's around 54" long? Would a surface plate that long work if I scraped both sides in simultaneously? Just...

    My Homemade Multi Rib Pulleys To Reduce Vibration And Add A Brake To My G4003g

    After reading post about vibration I noticed mine had a slight amount of vibration at times so I took a look at the belts while it was running and noticed how much they bounced around and I also noticed the large pulley was not running true as I could see wobble while it was turning and figured...

    South Bend Junior Introduction

    Hey, folks! I'm new around here (obviously). I recently found an old South Bend 9" lathe (in pieces) advertised in the local classifieds. I'd wanted a good metal lathe (and had an old 1941 craftsman wood lathe that included a compound slide for "light" metal turning). I saw the ad, and made...

    Craftsman Change Gears

    I have a Craftsman 101-28990 w/QCGB. I would like to know what size gears should be on the change gears when adjusting the QCGB for threading? Im assuming there is a neutral set of gears that are used when using the QCGB? Love this forum!
