    I Need A Gear Made...

    Update - first, I want to thank all the folks who chimed in and offered advice and their experience. With the help of Gene Poole and others, I have been able to basically completely rebuild the gearbox. New idler gear, NOS Pinion Shaft, I turned new bronze bushings, new needle bearing and some...

    I Need A Gear Made...

    I think I posted a pic of the gear in question, but I attached it again - the one you printed looks like a duplicate. (minus the wear LOL) Very impressive.

    I Need A Gear Made...

    I don't have another lathe - just a complete separate gearbox albeit an older version - but the older gearbox will "work" on the current lathe - and then I can source or make the needed gear and reinstall that gearbox when its up and running. There has been a lot of great advice and input from...

    I Need A Gear Made...

    I get that and totally understand - quite a few folks suggested Boston Gear. I had made inquires to them and they were very nice - I got a personal email from them that explained the small gear / one off type work wasn't something they could do as it was time and cost prohibitive. I do have a...

    I Need A Gear Made...

    So, I came here based on the knowledge and appreciation of these old South Bend machines and the vast amount of knowledge that members here possess. Apparently I was mistaken. This is a place to get schooled on by someone with an axe to grind about what it costs to make a part. I completely...

    I Need A Gear Made...

    I contacted him - waiting for a reply - he's the guy that makes the "silent reverse gears" I see.

    I Need A Gear Made...

    The quote from a company (who shall remain nameless in order to protect their type of comedy) was $2,775 for 1 or up to 6. They offer different levels of delivery - and the price goes up exponentially. If I wanted it in 48hrs - it was $11,100. Not kidding... (as an aside - I paid $800 for...

    I Need A Gear Made...

    The more I look - the more I begin to realize that this is really a unique item - read "obsolete" gear. The 27 teeth & 14.5 deg pressure angle is VERY uncommon - apparently used in OLD machinery. Still search & emailing...

    I Need A Gear Made...

    Currently I am refurbishing a 1945 South Bend 10L Lathe. Model 8187ZN - Tool Room model with a single tumbler quick change gear box. There is a single gear that has confounded me - can't find NOS, used ones are worn beyond what I have now. Like a crazy person, I humored myself by submitting...

    SB 10L Single Tumbler Gearbox - Parts Quest...

    Texas - impressive repair. I'm intimidated! It's interesting - the QCGB I just got (talk about lucky - on eB & turns out the guy was 12 miles from my house/ easy pick up) is an older model - QCG-100 with the single support for the idler gear. There is very little wear on any of the gears and...

    SB 10L Single Tumbler Gearbox - Parts Quest...

    I made inquiries to several gear mfr’s to include Boston Gear. All declined to make it. Boston Gear responded: “The gear you describe calculates to be an odd 14 Diametral Pitch. Unfortunately, Boston Gear does not offer this size gear as part of our standard line of open gearing and it would...

    10L QC Gearbox Bushing Question (Single Tumbler)

    More updates.. The process of cleaning and getting all the muck out is extensive. It seems and has become a familiar path that Mr. Murphy clearly lives close by. The more I di into this the more issues I am finding which in turn generate more questions - like a self licking lollipop. I had to...

    SB 10L Single Tumbler Gearbox - Parts Quest...

    Is that the same as Diametral Pitch? Looking at the offerings from Boston Gear - they don't mention anything about Pressure Angle.

    SB 10L Single Tumbler Gearbox - Parts Quest...

    Looking for two parts for my 10L Single Tumbler QCGB - been scouring all the usual places but with no luck. I need the gear that goes in the tumbler arm - I believe it is called the Idler Gear P/N PT605R1 and potentially the Main Drive Pinion P/N AS420R1. Any viable sources?... TIA

    10L QC Gearbox Bushing Question (Single Tumbler)

    Short update... I did the whole remove / replace drill with the headstock & gearbox - gearbox is off the machine and the headstock reinstalled so I can use it to make the new bushings. Got in the bronze cored stock and started out to disassemble the gearbox. Happy to report that it came apart...
