Atlas Lathe change gears

well today i'll be changing the Atlas Lathe change gears back to a fine feed for a upcoming boring job. you will see why people prefer quick change gears but on the other hand there are a much larger amount of threading pitches to choose from with a standard set of change gears. i hope you enjoy me stumbling threw setting up the change gears.

I hope you enjoy the humor of this set up but at least it is done. If you enjoy old machinery pleas subscribe for more videos like this.

Thank you

[@OldIronShops]

not a problem

How tight should the nuts be on these lathes? I think i over tightened mine and messed up the height of the keyed spacer thing.. didnt help one of the thick washers behind the nut walked away somewhere so just sanded a regular washer flat..

[@OldIronShops]

Snug should be good. if memory serves me the sholderef bolts are what you are tightening to not the gear it's self . As far as the washer goes you could turn one farly easy.

[@EvolventDesign]

Nice job Chris! You always need more gears and hardware to get it done. Looks like this machine has a single scissor that does “everything”.

[@OldIronShops]

Yes Andrew it's not so bad it would be handy to have about 4 banjos and you can get almost every basic setup . And just swap out the proper gear and you'd be good to go. I should see what a set of iron gears would run for this machine .

[@OldIronShops]

The one thing that people always miss on quick change gears is just how many options you have with standard change gears.

[@powers6963]

Great tips! Does that Lucas oil stabilizer run off the gears after sitting for a while, like if you don't use the lathe for a few weeks or a couple months?

[@OldIronShops]

It clings pretty well but I'd wipe things down and get some fresh oil on there after that kind of time myself.

[@georgespangler1517]

Watching you makes me really like my quick change gear box on my 12 x 36,,,, but the 6 inch I just bought is missing gears and it don't have the gear box

[@OldIronShops]

A quick change is nice but the change gears are more versatile. Many more posablitys .

[@georgespangler1517]

@@OldIronShops how many do you need,,,a quick change gear box has 108 combos,,,l think I'll be fine with that. Really only use 8, 16 and 24 anyway. And neither can do metric

[@OldIronShops]

You have a have a valid point. I have to sell it to my self some how lol.

[@OldIronShops]

@@georgespangler1517 just a side note the Atlas can do metric

[@georgespangler1517]

@@OldIronShops thanks, l thought I would have to buy a special gear to do metric. Taught me something

Hi Chris, If you have a friend with a wire EDM those double keyed bushing would be a simple project. Steve

[@OldIronShops]

+Solid Rock Machine Shop Inc. How much do you think for one? I suspect it may be cost prohibitive .

[@SolidRockMachineShopInc]

If you didn't have a friend that was helping out it would be pricey. If you provide the blank block with start holes already in it it would save cost. That type of work is perfect for wire EDM. I am just taking a guess that the outside profile burn time would be about 3/4 with 3 passes. Steve

[@OldIronShops]

+Solid Rock Machine Shop Inc. Hemming I may have to look into this. By the way do you know much about setting up spiral milling on a manual horizontal mill ? (It seems not many people do at least the ones that I have talked to )

[@SolidRockMachineShopInc]

Nope. That's a new one for me. Steve

[@OldIronShops]

+Solid Rock Machine Shop Inc. Lol Ion c email I get around to it I may post a video question to you concerning the situation. We are a ways off from that though.

[@rgsumpter]

On the drive bushing Clausing still sells them and the are about $10 each. The new ones are made from a hard plastic.

[@OldIronShops]

+Robert Sumpter plastic I'm not paying $10 for a plastic bushing. Maybe I'll make one.

[@rgsumpter]

Boston gear also makes one that you can get on Amazon. It is made of steel and is a lot more expensive. Boston Gear also makes all the change gears with steel. The gb series are for the Atlas ie GB64. www.amazon.com/Boston-Gear-GBB16A-Bushing/dp/B004NYAJ3M/ref=sr_1_1?s=industrial&ie=UTF8&qid=1507172256&sr=1-1&keywords=boston+gear+gb+bushing

Glad to see you got 3 levels of compound gear reduction. I cut my QC gearbox in 1/2 and can now cross feed a cut off tool into aluminum. What is the actual feed rate now?

[@OldIronShops]

+Crafted .0035 per rev

[@OldIronShops]

+Crafted you don't have any of the bits I'm missing do you

[@CraftedChannel]

Well, nobody actually saw me there so you can't prove anything. Actually, I do have a limited number of spares. The bushings can be turned so no reason for you not to make those. The coupler I have successfully 3d printed and I'd be happy to send you one of those. There are ways to machine those in metal as well. For another purpose, I'm working a tool that would make that simpler. But suffice it to say, machine a tube, mill a slot on each side, mill down slightly two keys, lay in slot, solder in place. The trick is in getting the slots perfectly opposed. (some play in the slots could be acceptable in place of perfect 180 opposition because change gears are available to hold the keys perfectly) I haven't figured out a way to do that perfectly with metrology and my existing tools. Although I'm going to figure it out and do it so I can put a Woodruff key slot in the opposite side of one of my broaching bushings so I can do a key, flip around and do another key. If one had such a bushing, you could drill a hole in a chunk of steel. broach it on both sides. Then you might be able to take a broach of the same width as the cutter and use it to perfectly broach both sides of the outside of a tube. A key would be required in the first broached slot to hold position for the second. Those are my general thoughts on the issue. Getting a Woodruff key slot in my broach bushing 180 degrees out of phase is the tricky part I'm thinking about. I don't have an indexing head. Your thoughts? I purchased the Woodruff key cutter a while ago proper for the job. I already had 6 or 8 but none the right size. I've been looking for a small horizontal mill to ease this kind of work and gear making. You could also cast the coupler in aluminum and scrape it into perfection using the carriage method. There must be some reason you need to pay penance. ;-) Would make for an excellent video.

[@OldIronShops]

+Crafted wow big response. Lots of good information I need to digest

[@OldIronShops]

+Crafted hey I have some of the thiner gears think there for the 10" lathe have any spars you'd like to trade for?

[@juancarlodflores8327]

What did you use to clean them an do have to grease them up

Hey Chris, thanks for sharing. Care to share your camera and recording setup? I need some real improvement in this area. I seen you control with your phone. What camera do you use and do you use a monitor to see what you are capturing? Sorry if these are dumb questions. I don't really know too much about this stuff. Joe

[@OldIronShops]

+My Heap not a problem been thinking of making a video of my film setup

Cool, I will, for one, be looking forward to it.

So what is a ballpark figure I would have to layout to set up like you are? Are you using a wireless mic too?

[@OldIronShops]

+My Heap $400 maybe less and that it's with a Bluetooth microphone

[@michaell4793]

Do you know how many gears are in a complete set and what gears they are. I recently purchased the same lathe and I cannot find any thing about what makes a complete set.

[@OldIronShops]

Get a copy of atlas lathe operation it has a bunch of Information about this lathe as well as all the gear setups.

[@michaell4793]

Old Iron Shops thank you I will look into that

[@OldIronShops]

@@michaell4793 well worth it if you can't find it I can figure out what a complete set would be .

[@CraftedChannel]

Let me know if you need some of those bushings. I can make them.

+Tony Pike what do you mean?

[@tonypike5785]

Chris Anderson the older ones took to long to set up thats all, but you by the way make a great video.

[@OldIronShops]

+Tony Pike thank you one of the perks the a change gear setup is many more thread options .but you pay for that with setup time. I'll need to do some more videos on this but I think there are about 5 or 6 set ups and just changing the lead screw gear will give you the different ratios . I do often wish I had a quick change gear box. Maybe I'll build one.
