With all the extra work you've already done on this lathe, maybe the Grizzly g0768 might have been a better starting point. It is advertised as an 8 x 15 lathe, has tapered bearings on the spindle, has a cam lock tailstock and comes with steady rest and follow rest and both 3 and 4 jaw chucks. Looks like maybe the same bed and ways, but for what you've already spent in parts and labor, the $1350 price looks pretty reasonable.
I finished my install of my 16" bed last weekend and this video was a huge help. I didn't even bother reading the instructions after watching this once or twice, just dove in and everything is better than when it was a 10". Awesome job documenting the process and many thanks.
Nice upgrade - a fair bit of work needed - but nothing that could really scare a guy who can rebuild a Mustang automatic transmission!
I cut the small end of my drill MT2 taper so it fit farther in but still popped out when I turned the crank to 0, and It gave me a little more room. I have a quick change tool post like that and it is as tight as a new bride, and am really happy with it. I superglued the handle in and it has worked good.
this lathe is in metric not imperial measurement, so making any modifications in imperial instead of metric is mistake
My 2nd time watching this vid to refresh my memory as I just got serious and pulled the trigger on this for my 93799. The extra 4 inches is going to be AWESOME! Thanks again.
I figured you were going to connect the 2 beds together.
This video got me to buy this from LMS. Thanks for sharing. I didn’t even know this was a possibility..
Always look for a lathe that has at least a distance between centers that is twice the swing of the lathe for the reasons shown in the video.
Nice job on this upgrade! Not for the faint at heart, for sure. You have pointed out several weaknesses of this lathe, but you are getting the problems resolved. Thanks for sharing.
I just completed my upgrade-your instructions for disassembly and reassembly were awesome, thank you so very much! 7x16 Yay!!!
Just to clarify lathe specifications. The three principal working parameters are swing over the bed, swing over the carriage and length center to center. The swing specs are pretty straight forward but the C to C spec needs qualification. It is generally understood the working length of the bed does not include "accessories" such as chucks and rolling centers. The actual spec refers to having dead centers inserted into the spindle and tailstock. With that in mind the advertised spec is probably correct. It is up to the buyer to determine actual working dimensions based on their use case.
You sir should be a machining instructor. I cannot believe how thorough you are with every aspect of rebuilding your lathe. I dont even own a lathe or endmill but stayed and watched this to the end just because of how you explained everything perfectly. This video is getting saved for future reference when i do buy my lathe from harbor freight. This is why i dont understand people who rag on me for buying things from harbor freight. With a little bit of TLC and upgrades you can make anything from harbor freight perform as good as the big name brands. Well done sir.
Thanks so much for the information on your quick change tool post. I have been looking about ordering a 7"X16" lathe and a quick change tool post set. You have been great help. Good luck with your lathe modification.
Great job! The crickets background noise was great a real homey sound to your build, better than the background music some of these videos have!
It is actually ten inches from a dead center in the spindle and one in the tailstock. You probably could have made it work by putting your bar between centers and secure the bar for turning with the face plate a a lathe dog.
Ooo woooooww i never knew they sell a extension bed thanks!!!
The finest lathe video I have ever seen, on this topic. Very clear video, instructions, and easy hearing and understanding talk. I give you an A+++++++++!!
Great video, nice and thorough! I could listen to your voice all day
