Let's build the world's first Aftermarket 2-Speed Tailstock Gearbox. We are crazy and we know it. Enjoy watching 500gb of footage crammed into 32 min of solid action!
Nice job! I have a suggestion which I learned myself. Really simple stuff can be made without mistakes going along. If it get's a little more complicated, as your gearbox certainly is, it really pays to make a plan in CAD or an reasonable accurate sketch by hand before start. I know it's an extra effort, but it pays of when you make stuff. Ideally you only have to handle/machine a part once and when assembled you're done. Off course tweaking is always a part of the process but adding length to already cut plates doesn't have to happen when you work like this. I'm a designer/builder for 28 years now and I learned the hard way. Get an idea, make a drawing and select all the materials you need when doing so. Make simple drawings to print (or draw) for the parts to be made. Make the parts, assemble and be happy. Hallelujah! Thank you for sharing your honest journey! Best! Job, the Netherlands
Thanks for the feedback. I know it to be true. I just didn’t know how to use cad at the time. Learning the program was on my goal list for this year and I started this project last year in October. I’m already knee-deep and using fusion 360 as we speak.
Nice job! That's a factory feature on most Kingston Lathes. They give you selectable 1:1 or 5:1 ratios. Very handy feature to have! I use it quite often.
Nice work, you are a braver man than me designing something like that on the fly. Looks like it is working for you though. I like your filming style, saves me skipping ahead while people take measurements and tell me how many extra thou's they are going to take off.
I own an old herbert no.2d turret lathe, it was a tail stock auto feed with 3 rates of feed ran off of the saddle feed, not much variety but you dont really need 50 different speeds for drilling. An old lathe but a beast
12:50 That rubber work mat in this shot, is fairly expensive! .. I made an apartment in my house with a closet turned into a tiny toilet and shower! :) ... I used this rubber mat stuff for flooring! ... VERY slip resistant and with the 1/2" X 2" Plastic baseboard, and generous use of silicone sealer?? It made the little washroom floor 100% water tight!
Finally someone who is actually roughing with their lathe and not babying it. Healthy feed, speed, depth of cut. What depth of cut did you take? 4mm? 5mm?
Worlds first is a little stretch here. My Lathe at work has a selector for direct drive or a 1:5 reduction on the tailstock. That machine is from 1998 !
2 speed tailstock are extremely common. What I have never seen before is someone adding a legit one to an existing unit. That is the first. If you have proof of someone else doing this send the evidence my way!
Good stuff. That bandsaw was frigging flying though. I’d change the speed on it and it should be able to get through 4130 no issues. I cut alot of inconel with surface speed of about 60 feet per minute.
Holy Smokes 19:19........that is Art my Friend.........very tasteful and beautiful..... I don't know much about art, but it would look great with my carpet, drapes and furniture........ Seriously, do you have a background in art, because the video you shoot and capture and this or of attention to design and detail sure makes it look that way......Best Wishes from Florida, Paulie
No I don’t just ocd. Never picked up a camera before RU-vid. All self taught on pretty much every skill I got. Took a few college classes in welding and automotive but other than that I am 95% self taught.
@@hilltopmachineworks2131 yeah it is. Honestly you can also make a good one it’s nothing special from an engineering point of view but it is the nicest premade one there is. I have all the different bar sizes. Rigidity is the key to success though. I use it on the bp mostly with the shorter bar. It works well but is less effective as you go bigger on diameter just w vibration. On the k&t it’s like cheating, so ridged, basically perfect finish every time insert is not damaged.
@@VanoverMachineAndRepairTheir sinusoidal flute profile helps reduce cutting force but in theory should still leave a smooth finish. Weldon marketed/markets these as great for titanium and exotic alloys. Should also reduce chance for chatter considerably.
Please tell me your welding jig was an old, no longer used mill table. A thin layer of MIG nozzle gel will save or minimize cleaning up any welding oopsies on the mill table. Nice looking fab job...
Hell yeh Are you going to get as in depth with that Lucas HBM you mentioned in that update vidya as you are with the Lion? Because this series has been amazing
No lol. I wish. Maybe… but probably not this project is 2 years long maybe 2.5. I can’t have my hbm down for 3-4 years I need it to start paying for itself but you know me even cleaning it up will get some upgrades and fixes done just have to set a deadline so I can actually get it running in a reasonable time.
I enjoyed the video and the machining, but even after watching the beginning several times, I still missed the reason why you want a 2 speed gearbox. Is it that sometimes it does not go the full distance fast enough, or you want to be able to go in slower sometimes for delicate drilling? Maybe it is me and just missing the explanation. Hopefully someone can enlighten me so the reason matches the fun video of machining. :)
It just adds more capabilities. On most nicer machines they have two speed tailstocks especially on bigger machines. Fast speed helps bring quill in and out quick where as low speed reduces input torque required on handle for big drills
22:22 Darn Engineers are always making design changes after you already made the part..... Great Modification........D.E.S.S.A, [Darn Engineers Society Seal of Approval]
Are you no longer using any thrust bearing for the screw to case, as was originally designed? You do not want to have axial load on plain bearings…which is what it looks like you are using. Maybe you just haven’t showed us the full plan yet.
Excellent. Many lathes have two speed gear boxes. the newer lions come with them as well so I really wanted to add one to mine to bring into the newer style.
My lathes are not set up for coolant. This new lathe will be. I got brand new oil set up and k&t but it’s such a mess. Mostly it makes a mess and it’s makes it hard to see on video.
I like that you're building something useful and interesting, but I don't think this is worlds first :) There are engine lathes that ship with 2 or 3 speed tailstock gearbox, primarily to help with drilling operations.
