Will it work? - Making a lathe indexing attachement - Part 2

[@dariushmilani6760]

I think metal parts will be more accurate and better rigidity.👍👍

[@joneseymakes]

Yep agree. I’ll get around to that soon.

[@srankin8022]

Great design and idea! It never cease to amaze me that people actually think they can 3d print accurate parts out of plastic! Make those pieces out of aluminum at the least and even better hardened and ground tool steel.

[@joneseymakes]

Thanks. This was more of a prototype to prove the design really. I will be making this from metal in a future video.

[@andrewdolinskiatcarpathian]

Whilst version 2 was a clear improvement over version 1, I definitely am interested in seeing you make a new one out of metal. Looks like a very useful addition to your lathe. 👏👏👍😀

[@joneseymakes]

That's the plan! Thanks for watching.

[@HolosunGodOdin]

Would love to see you make a metal one! Well done!

[@joneseymakes]

Coming soon! Thanks

[@dailrharris9009]

Yes please, not all of us have printers

[@petermarsh4993]

Hi, I agree with the idea of making the plates out of metal. Plastic is fine for prototyping but not for the long run. Cheers.

[@joneseymakes]

Thanks Peter, there will be a follow up video soon.

[@berkakarcaloglu1915]

One specific recomendation for the 3D prints. I'd suggest you take a look at modifier meshes. Even the default ones in Prusa slicer would be greatly helpfull in your case. For example add a modifier near the holes and make the infill 100% around those holes or adding extra perimeters around the holes. this could really help you with having rigidity where needed and saving material where you dont need it.

[@joneseymakes]

Great suggestion Berk, I hadn't considered that. Thanks for the tip.

[@samimas4343]

Fantastic job there, mate. Thanks a bunch for sharing.

[@joneseymakes]

Thanks, much appreciated!

[@ObviousSchism]

I love it when the engineering big guns are brought out.

[@Thats_Mr_Random_Person_to_you]

I think that's a really great debugging session!! I think of course metal would last 'longer' but equally, I don't think it would be too hard to modify the 3d printed parts to put metal bushing into the holes. I think with bushing the main cause of wear will have been removed, but over time with some of the side to side forces you would see the plastic eventually deform and creep, but thats on a timescale of years.... so hardly a concern. Love the work soo far!

[@joneseymakes]

Thanks! Good idea on the bushings.

[@Michel-Uphoff]

Yes, please make a metal attachment. I don't think 3-D printing is the way to go with this kind of rigid precision parts, and I still see some irregularity in the spaces. The basic idea however is in my opinion very good. With precisely manufactured parts, preferably made of steel, this can be a very useful addition to the lathe.

[@joneseymakes]

Thanks Michel, I plan to make the metal parts soon.

[@colintwiss]

Good Prototype Jonesy so now you have proven the design make it more robust in a good metal. NOT Aluminium too soft for the precision you will want.Well done mate

[@joneseymakes]

Thanks Colin, will do!

[@htchtc203]

Thanks for sharing the final endcome too. I am planning to copy this to my tiny Proxxon PD250/e. I am probably going yo use brass inserts for indexing holes.

[@joneseymakes]

Sounds like a good Plan!

[@mattymcsplatty5440]

yep metal for sure. great job improving the printed one tho. The !0 and 5 degree scribes lined up well on the full circumference but the 1 degree is a wee bit off sometimes. I still think aluminium or steel plates will make the acuracy better being rigid. Looking foward to seeing it

[@joneseymakes]

Yep. I’ll get to making a metal one soon.

[@russtuff]

That's a killer result.

[@joneseymakes]

Thanks!

[@kennethstaszak9990]

Nicely done. Good job on figuring out the accuracy issues.

[@rocksolidhugo]

Great stuff

[@MyLilMule]

Nice save!

[@joneseymakes]

Thanks!

[@f.hababorbitz]

If you put another circumference of holes, like 20 inside the 36 (at a small radius and match those holes for divisions of 10, less then a degree), you could do divisions where feed screws are 1/5 or 1/10 leads per turn, like milling and lathe, this will enable 100 or 200 divisions in the circle. For the odd lathe I have where 8 comes out, then an another inner circle of holes at 25 divisions, so 125 or 250 divisions can be done (this would be between the 36 and 20 hole circle). Nice project, and good video production. Thanks.

[@joneseymakes]

Thanks, good idea. I think I might incorporate this in to the next version

[@thomasvnl]

Perimeters, especially when having to modify holes afterwards for a perfect fit, make the most difference in terms of rigidity and also in having enough material left after modifications. Cubic or adaptibe cubic appear to be the most rigid infill as well.

[@joneseymakes]

Thanks, good advice.

[@evzone84]

Try turning and pressing in brass bushings. You'll get stronger, tighter tolerance, and more wear resistant holes with the same 3d printed part. A nice compromise between production speed and functionality.

[@joneseymakes]

Yes, I like that idea

[@mattylarkspur9858]

came here to say this!

[@OhHeyTrevorFlowers]

If you’re worried about creep of the prints it might help to put a slit and clamping bolt in each to hold tight to the aluminum part.

[@joneseymakes]

Good suggestion, thanks.

[@vanViz]

Don’t know if anyone mentioned it yet , but my suggestion will be to countersink the holes 2mm or so and add matching boss to the pin- I believe you’ll improve the play in the pin and minimize error due wearing of the plastic. And carbon filled PLA will be more rigid and wear resistant too . As I’m just shed professional with YT degree, i can be wrong for both…😁

[@joneseymakes]

Sounds like a good plan, thanks for the tips!

[@taranson3057]

Aluminum plates would be much more stable than the 3D printed plates, just the nature of the material. The 3D printed plates can still be of some sort of use, perhaps in woodworking where the dimensions aren’t nearly as critical, I can think of a few jewelry craft tools that are made of wood that require line divisions and these 3D printed plates would make the process much easier. Just a thought.

[@joneseymakes]

Thanks, good idea.

[@MolonLabe1976]

Excellent tool. The design is probably the best I've seen, but I am very eager to see the newer version with metal plates instead of the 3D printed ones. I will definitely be making this for my lathe, but I'm holding off until you have the updated version. Great videos and explanations. Thank you so much for sharing. When will you be doing the updated build?

[@joneseymakes]

Thanks, much appreciated. I will be doing the metal version with the next two months.

[@joneseymakes]

I might offer a kit version with materials and printed plans. Do you think people would be interested in that?

[@MolonLabe1976]

@joneseymakes Awesome! Really looking forward to it.

[@MolonLabe1976]

@joneseymakes Yes, absolutely. I would buy it. As long as the graduation issue is resolved with the metal plates, I think it's a great idea. A kit with plans and material to machine the parts, or even just the prints so that people can source their own parts...I think either. Thank you again for sharing. Great content!

[@OneManEngineering]

Defo metal for accuracy & longevity of those parts. Also eager to see the dovetail part that you’ll use for scoring/splines/keyways etc. new sub from me for sure! Greg

[@joneseymakes]

Thanks Greg

[@davidjohnson6965]

Another fantastic video! Thank you!

[@joneseymakes]

Glad you enjoyed it! Thanks.

[@Kevin-gx8lc]

Hi Jonesy! Great video. Yes.... let's see them in metal (maybe stainless...?). Greetings from Southport.👍

[@joneseymakes]

Thanks Kevin! Will do, stay tuned.

[@Frogmood]

I bet making some metal inserts for the holes in the plates would help with longevity of the part.

[@joneseymakes]

Good idea, thanks.

[@bobweiram6321]

Metal is ideal, but Perspex is a close second if you have access to a laser cutter. It's also pretty ridged. Over a certain thickness, it will crack before it bends. You might find ways of exploiting its transparency to simplify your design.

[@joneseymakes]

Good thinking Bob, I hadn't considered Perspex. I don't have a laser cutter unfortunately so it's going to be about the same effort to make them in metal

[@obinstefjord8079]

You might recall from my comment to your last video, I kinda mention your reaming of the holes... ;-) Anyways, great improvement, and I would love to see it in metal!

[@joneseymakes]

I remember! I'll be making them in metal so stay tuned.

[@4GibMe]

I know this is a year on. But, if you can perfect this, you could save allot of home shop owners allot of money. Or, even, give them access to something they simply can't afford, otherwise. Thanks for everything, Uncle Jonesey. :)

[@joneseymakes]

Thanks, I have another video in the pipeline where I'm going to redesign and re-make this in metal, I think that's going to solve the last of the issues. Thanks for watching!

[@mrimmortal1579]

@@joneseymakes Do all of your setups as rigidly as possible (in other words, no teaming of holes while holding the part in your hands on top of the vice). Use the hole-pattern function of your DRO to drill AND ream the holes, so that you don’t introduce unwanted error. Also, look into picking up a tapered reamer to use on the holes in the backplate. Then just make sure that you machine the matching taper onto the pin. This will further reduce any error by more accurately centering the holes in relation to each other.

[@mikew9292]

Brilliant

[@joneseymakes]

Thanks Mike

[@jrkorman]

I'm not OCD or anything, but, there was enough inconsistency between the degree lines that I'd have thrown it in the bin. However, it may be that only the vernier part needs to be made in metal to higher precision. I'll be watching to see where your experiments take you.

[@joneseymakes]

Thanks for the comment Jim, yes it's still not perfect. I'm hoping that it will be once I make the parts in metal.

[@kimber1958]

very cool

[@joneseymakes]

Thanks!

[@EitriBrokkr]

if you remake it, use a taper pin and taper reamer. then it will be impossible for it to not align properly on the hole

[@joneseymakes]

Good tip, thanks!

[@EitriBrokkr]

@@joneseymakes have you thought about using a hirth coupling between the plates. That might be an interesting idea.

[@joneseymakes]

@@EitriBrokkr Yes indeed, not considered that. I'll have to work out how to make one first!!!

[@EitriBrokkr]

@@joneseymakes the beauty of a hirth coupling is as it wears it just locks more and more accurately and more solid

[@wizrom3046]

You can't polish a plastic turd... But you CAN print it with more infill! Really cool videos, it is interesting seeing you turn what was essentially an unusable concept into something functional. A suggestion; if you stick with 3d printed plastic for the next iteration you could increase the diameter, ie the radius of the pin from the chuck centre. That will increase the rigidity at the cutting radius and reduce the angular error caused by pin and hole issues.

[@joneseymakes]

Goo tip, thanks for that. I think for the next iteration I'll go with metal plates now that I've proved out the concept.

[@stillraven9415]

When you were hand reaming, you twisted the reamer backwards making it hard to actually cut accurately as well.

Good spot, I hadn't realised I'd done that.

[@EngineerRaisedInKingston]

Hey Mr. Jonesey - loving the content as usual. Quick question - how is the new lathe? Any comments or suggestions? I'm eyeballing a similar model to your's and just wanted to see if you've had any input regarding it. Cheers!

[@joneseymakes]

Hi Erik, yes I like it. I made a review video where I spoke in depth about it. Have you seen that? kzbin.info/www/bejne/j6etXp2roJ2XhMU

[@EngineerRaisedInKingston]

@@joneseymakes I have indeed! And a brilliant review it was. Just wondered if you’ve had any things come up in the time you’ve had it, things you wish it had etc.

[@joneseymakes]

@@EngineerRaisedInKingston No I'm pretty happy with it. Small niggles, like the lead screw covers get in the way etc but I spoke about that in in video. One thing though - you still have to change the change wheels when switching between threading and feed gears. That's annoying. Would be better if there was a lever instead.

[@ryanpeterson5239]

It's a shame the holes have to be so close together or you could probably solve the issue with a metal bushing glued into each hole. of course that would also require the holes to be larger. could you increase the diameter enough to allow for larger holes and more space between them?

[@joneseymakes]

I don’t see why not. Depends on how much clearance you have on the back of your lathe I guess

Hi Jonesy, hey just curious if you ever did a metal veraion of this? I'm very interested in your design, but something that is more consistent than the 3-D printed version and keeps the graduations dead on.

Thanks Robert, I wanted to prove out the concept before making it in metal, I find it easier to work that way for these kind of projects.

[@BruceWSims]

OK...as a mini-lathe owner (see: Sherline) I have a great interest in what you are doing. However, I have to call "foul" on using your printer. I wouldn't mind if you had to cut this up into two or three video parts if I could be treated to watching you do All of the work on your lathe. For us DIY-ers, watching someone bounce back forth among a lathe AND a mill AND a printer sorts negates the point of watching your video cuz we don't have all of your toys. Help?
