  • Reading back through the thread a bit there were a few mentions of the drill chucks. The chucks (tailstock and mill/drill head) and keys were kind of a disaster on my 1340. The two no-name chucks didn't take the same kind of key (one used a Jacobs pattern and one didn't), one of them didn't hold well, and neither of them worked with the keys that were supplied. I needed a new chuck for my drill press so I bought a couple of new Jacobs (name brand) chucks that all used the same key and an extra key. Now I can grab any key from anywhere in the room and it will work, and I often use two keys at once to hopefully get a more even tightening force.

    If I get around to it I would like to gear the motor down a bit and clean/inspect/replace? the lathe spindle bearings. I have a lot of flex in the spindle that I think isn't actually flex.

    • Smithy makes a speed reduction pulley kit for the 1340. (Product Code: 40-300G ) I installed it on my machine and would recommend it for slow speed work. It also helps the motor run cooler because the motor speed stays high enough to provided fan cooling even though the machine is running at slower speeds.

        Smithy says, "Item no. 40-300G is not required on Granite MAX and Granite I-MAX Series or on any Granite models manufactured after September 2004." Apparently they already have this. My machine is labeled Granite 1340-MX on the mill head and G1340MX on the data plate, but I do not seem to have this. My motor spindle has a 2-speed pulley that drives the lathe spindle directly.

        I keep it in the slow position, and it goes plenty fast for me. What would people use the fastest combination (apparently 2800 RPM) for?

        • Answering my own question here, based on info from the Smithy Yahoo group. When Smithy phased in the 2HP brushless motor (to replace the 1.5HP brushed motor) the speed reduction kit was considered unnecessary. One of the members of that group upgraded his Granite to the newer motor and removed his reduction kit, so I guess there is truth to the idea. The new motor does have pretty good low-RPM torque.

          Torchroadster, do you have the old motor or the new one? The new one has a square finned aluminum housing with a controller box mounted behind the machine.

          • Wanted to know if anyone with the 1340 Granite has encountered a vibration when using the Lathe.
            When I take mine out of gear the vibration goes away. As I am looking at the Gears in the Pulley Box, I notice when the Lathe is engaged I can see the Upper Spindle moving with quite a bit of runout and that runout matches the rotational vibration.
            It also happens when the Mill Head is activated because the both work off the same Upper Spindle.
            I will call Smithy to find out what to do but wondered if anyone here as ran across this and has a fix for it.

            • I bought a new Smithy 1220LTD, early 2019. Thought I already had enough tooling to get started, ha. Have since purchased more tooling than the cost of the machine, and that doesn't include the 4" Kurt vise given to me. I chose the smithy due to space limitations and because of it's weight, thinking that would translate to rigidity. And it does in the lathe but not the mill. I'm not dissatisfied but coming from Bridgeports at work, there was an expectation. I've added DRO, QCTP and depth stop on mill head. I've milled a small relief in the tailback base to clear the carriage and gained 1.5" approaching the chuck. Am currently working on installing a 1 hp, 3 phase motor with VFD on the mill to attain slower speeds and quicker speed changes. Have all the parts for a Clough42 electronic lead screw which will make using the table power feed quite useful. With the DRO and holding my mouth just right, I can hold .0005" tolerance, but casual machining is .001". Though I didn't buy the Smithy to make money, I did a job that paid for it several times over. Not bragging, just wanted other owners and potential buyers to be open minded about the Smithy line.

              • Any one have a steady rest for a 1220 that they don't use??
                Thanks for any help!

                • Any one know the angle of the 1220 bed ways? Going to make a stop /
                  dial indicator.
                  Thanks for any information.

                  • Earlier this year I bought a new Granite 1324 with DRO and the new brushless motor. I sold the older model I had just to get the DRO and brushless motor features of the new one. I have been a woodworker since 1967, and spent 20 years or more making a living doing only custom woodwork. (insert long varied careers) After several years of "retirement", wife suggested I take a welding course at the local college because as a senior citizen it was free. So I got into metal working both fabricating and machining. (Little did she know......$$$$$$$) In one of my efforts to earn money I spent three years in a machine shop as a programmer, so machining wasn't new but the welding part was. Long story short, I ended up with a pretty well equipped metal shop AND a woodworking shop. It's all jammed into about 1200 sq ft at our "new" residence in southern Indiana. (We're IL refugees seeking asylum in IN).

                    I'm glad to have found this thread just to hear about other's experiences and share my own.

                    The used Granite 1324 I bought had been dumped on it's head at some point in the past and the repair was pretty decent. I ended up putting a new motor on it to replace the abused one that failed. Abused because it was run too slow to cool itself and it died. Found the jack shaft parts and installed them with the new motor no problems thereafter. Until I got the wants for the capability of the new brushless motor and DRO. So far I'm liking the DRO but as mentioned a while back, the manual is Chinglish and takes a bit of code breaking to work through it. Only tackled beginner stuff locating holes in a plate etc so far. I also own two Fox Supershops (that use the same motor and controller as older Smithy....stuff is 1975 tech) and one of their lateral feed gear motors ate a small gear that I need to make. I've studied on that problem of making this odd little gear for almost a year now, and have begun to understand what I'm facing. The company that made the motor is alive and well in St. Louis, but they had a catastrophe and cannot supply anything of their old motors by part number. They don't have good customer service that might go measure and pick one, so I will take up the challenge of making it. I have to find the parts again that got shuffled in this move, then find the papers that remind me of what I have and need to make. I've read through all the gear forum posts and am fascinated by the home made tool forum.

                    • Good luck with the gear! I've had my 1340 for over 15 years, and I've done a lot - but I've never machined a gear. Show us how it turns out!

                      • Will do, but it might be later in the fall before the round tuit surfaces. It can't be postponed indefinitely because I want to be able to use the lateral feed on the machine where it broke. Fortunately I have an intact gear to compare to if I take the other machine's lateral feed apart. It's a compound gear, meaning a larger and smaller gear are pressed together and it was the smaller gear that stripped. They look like sintered metal pressed into gear shape and the broken parts are ragged, sharp, and crystalline. So a mild steel gear will be much stronger. It's a small diameter gear with 11 teeth (ugh), so my gut says a cutter, (the smallest made) for 12 teeth would not work very well. But I have no experience to make that call. I'm intrigued with making a cutter (zero degree hob) and indexing the blank to get an approximated faceted volute. I think that would work very well. I will post a couple pictures of the before with my calculations to be verified.
