SPIN INDEXER IMPROVEMENTS: Flip It!

[@StefanGotteswinter]

Thanks for sharing! Totaly doing this to my spindexer :)

[@woodscreekworkshop9939]

Hi Stefan, thanks for motivation.

[@samueltaylor4989]

Look forward to your take on this spindexer project, Stefan! Nice project!

[@michaelmiller5566]

This comment is awesome lol

[@woodscreekworkshop9939]

Tony Wilson as far as the career goes, there are only 3 requirements. 1) you have to enjoy it 2) you have to be good at it 3) has to make financial sense. You can’t build ALL your tools because you won’t have time to work on paying jobs. You can buy all top of the line tools because you’d go broke. You can learn to use inexpensive tools by knowing their weaknesses and work around them and that makes most sense. You can make good parts with a worn out machine. I checked and the bore is aligned with the face of the indexer. Thanks 👍🏼

[@andrewdolinskiatcarpathian]

If Stefan likes the idea, what else is there to say. 👌😀

[@Indiana_John]

Not only was the machining amazing, but the filming and editing was spot on! Great content man!

[@jefflyon100]

A wavy washer would preload the thrust bearings and give you zero front to back play. Thank you gor posting this. I've been thinking about turning one of these into a powered workhead that I can also index with using a stepper motor. This has given me all the information I need to go ahead and try. Hopefully I get one with an accurate enough spindle to do so! Thanks again.

[@billmaguire6216]

The facing ability of that boring head is fabulash. Super cool!

[@woodscreekworkshop9939]

It is! Thanks Bill

[@raysimon1368]

Great job back in the early eighties I was a tool maker in a machine shop and I tried to talk the boss into buying a suburban spin indexed but he didn't want to spend the money so he bought me a new phase 2 to replace the old one back then I think they were 30 dollars I always wanted to put tapered roller bearings in each end of the old one but never did a d never thought of flipping the spindle around all the times fighting with the guard on the surface grinder that was the best idea of this build if anyone else has ever used one then you know how nice a simple flip will be I'm retired now but still have a Cincinnati tool grinder lathe and mill now I'm going to have a flipped spin indexed thanks you do good work

[@raysimon1368]

You done a great job on your build back about 20 years or more ago I was a tool maker used a spin fixture just like yours think it was a phase 3 anyway all I did was to buy a thrust bearing for both sides instead of one it was available off the shelf no machining but I did not think about flipping it my boss was already complaining that I took it apart and bought 10 dollars worth of upgrades to it I was wondering why you didn't put a bearing on the rear I remember it making a big difference been going to do a better job on mine now that I'm retired was going to machine both sides for a tapered roller bearing never got around to looking for the bearings but your way would be good but I prefer a bearing on each end nice job

[@metalillness5951]

Well done sir! You have nice equipment in your shop. I enjoy the manner and pace in which you narrate your videos.

[@woodscreekworkshop9939]

Thank you🙏🏼

[@officialbritishtaxpayer5609]

Brilliant! I have one of these spin indexers and you've given me lots of ideas.

[@reddcube]

Thanks for the DRO bug explainer. It's a good reminder to do a scratch pass to make sure the DRO is programmed as you intended.

[@joewhitney4097]

Great video and build Yuchol. Very interesting and well done. Thanks for sharing.

[@glennfelpel9785]

Thank you for including the McMaster part numbers that is so very helpful. Much appreciated and you work is outstanding. Looking forward to seeing you make use of it. Thank you for the video too, stay safe!

[@836dmar]

Just watched this again. Excellent idea and execution!

[@ronslaughterandalice1018]

I have used these for years and the first thing I always do with disapointment is get it on the surface plate and find the center height and then the true plane and that is where the disapoinment comes in. I bought a new one and before I can trust it I know the base has to be ground in to the true plane .

[@tomt9543]

I don’t know how, after a year and a half of watching KZbin machinists, I just found your channel this evening! VERY well done, understandable, video and really liked things like the McMaster part numbers! You’ve got a new sub! I just received the exact same spindexer from Little Machine Shop today, and actually had to give it several attitude adjustments with a soft hammer to break the spinning part loose, then a good cleaning out was necessary. Thanks for sharing!

[@woodscreekworkshop9939]

Thanks Tom, glad you enjoyed it 🙏🏻

[@lolamann110]

fantastic work & execution, i will improve my indexer in exact this way. Many thanks to you.

[@samrodian919]

Hi Youchol. Long time no see! I've not had you come up on my feed for nearly two years, and you have popped up this morning! So I'm happy to be back with you. A nicely thought out and executed job making it very practical for your cylindrical grinding projects. It looke really good and I think motorising that will give you the consistent results that you are looking for. Hand cranking, just like running a lathe will just not look as good.( or be dimensionally stable) cheers from England!

[@ianjeffrey3637]

beautiful work yuchol - very nice design approach

[@johnmcclain3887]

Thanks for sharing this, I've had a spindexer for thirty years, never considered upgrading it, but I like the whole idea. Very well renditioned.

[@MartinHubbard1]

Very clever upgrade, lovely work and a pleasure to watch. Thank you.

[@woodscreekworkshop9939]

Thank you

[@rightwinggunslinger1]

Thanks for letting us know the oem front is lathe turned and the most accurate to work from. I will clean the sides down and be happier now. Peace from minnesota! More vids!

[@SweetTooth8989]

A new machining channel. Didn't even know about your channel until it showed up in my recommended today, I subscribed! I like the mods you made to the spin indexer.

[@woodscreekworkshop9939]

sweet tooth glad you found me, stick around 👍🏻

[@465maltbie]

I was thinking about swaping ends on mine as well, thanks for sharing. Charles

[@larrykent196]

Oil hole... I like the results solving a design flaw, cool. I did modify my spin indexer works much better thanks for the idea and video. Cheers!

[@brandontscheschlog]

Very cool! I’ve been wanting to do this to my 5C indexer but figured I’d wait until somebody else showed me how to do it. Thank you!

[@woodscreekworkshop9939]

Brandon Tscheschlog thanks Brandon!

[@AmateurRedneckWorkshop]

Great bit of craftsmanship. I am certain the spindexer is greatly improved. I have had one of those for a couple of years and I have not yet used it for anything.

[@woodscreekworkshop9939]

Thanks Harold!

[@larryshaw6517]

Always fun to watch you work, you seem to like going the extra mile for quality. Thanks

[@woodscreekworkshop9939]

Thanks Larry 🙏🏻

[@douglasbattjes3991]

Such a well done video, you covered all that needed to be covered. Well done and nice music, 👍👍👍👍

[@EverettsWorkshop]

That is an excellent overhaul of that unit. Some form of spin indexer is on the wants list here but there have been a few other things that were higher on the "available at a good price" list, lol. If/when one happens here I will definitely be reversing the spindle like you did, that was an awesome idea.

[@woodscreekworkshop9939]

Thanks Everett.

[@mechaform]

An excellent idea. Thanks for sharing.

[@Rustinox]

That's a nice project. Lots of different machining operations and lots of thinking.

[@woodscreekworkshop9939]

Yes, my brain hurt 😭

[@jpia5784]

Excellent Video. Well presented. Keep up the good work

[@billbrennan8405]

For a hobby you have a very nice shop and the talent to match. Great Video

[@woodscreekworkshop9939]

Thanks Bill!

[@dannyl2598]

Thanks for the video. First time here. I really admire how clean and well kept everything in your shop is. You are more than a hobbyist.

[@woodscreekworkshop9939]

Danny L thanks. I clean up for every project so the viewers don’t get distracted. A good motivation

[@jerdebson]

Great job on the refresh. Just found you today. Subscribed. Jerry.

[@woodscreekworkshop9939]

Thank you

[@44mod]

Great job i learned a lot about the way the hole piece is made. I like the way you and then disassembled everything back together. Perfect job explaining how you where going to do each machining step. I have a Harbor freight big mill and a Grizzly G602 Lathe. I like and Subscribed to your channel. Look forward to seeing different projects on your new Sin Indexer. God Bless and thank you.

[@woodscreekworkshop9939]

Thanks for your kind words, enjoy 🙏🏼

[@garytodd5605]

I see this is a year old. Very nice, useful project. The extra clerence will make using the indexer much easier especialy while cutting indexed bevels. I will be adding you to my viewing. Glad i found your channel.

[@woodscreekworkshop9939]

Thanks Gary

[@papaburf7275]

Very nice work and love the attention to quality finishes. Thanks for the content.

[@woodscreekworkshop9939]

Thank you so much

[@gangleweed]

Well, Well......just what I needed to see.....having just bought one of these on AMAZON the build quality is stated by a reviewer as abysmal, so as it was so cheap I just had to get one and then tart it up to better than new standards........I already have a dividing head but what the heck, I've got a full set of 5C collets on my Cuttermaster T&C grinder so I might as well...... too many tools makes you happier than ever. Edit.......contrary to what they say, the build quality of this indexer is very good and not the "abysmal" quality some reviewer stated. One thing I'll change and that is the ring that holds the index plate to the spindle when it gets flipped.......I'll use a split ring with a side locking screw to clamp it to the spindle.....I never liked screws pressing down on a shaft for retention. After deep consideration I won't fit the thrust bearings either........there is no thrust to cater for so a plain bronze thrust washer will be more than adequate to stop any end play.

[@antstephenson9497]

Great video including the DRO detour. One never stops learning, but thanks for sharing that.

[@woodscreekworkshop9939]

I learn a lot through all my mistakes

[@Rabid_Rat431]

Great content. I just found your channel and now I'm subbed. Looking forward to more of your videos!

[@joeybobbie1]

Nice Work, that really did come out nice. Thanks for sharing. 👍

[@woodscreekworkshop9939]

Thanks! 🙏🏻

Thats a 👌 boring head..... that dividing head looks familiar those things are a great value i think.awesome work!.........stefan was here thats exciting haha

[@woodscreekworkshop9939]

Thanks!

[@carneeki]

I love this! I packed my spindexer to take to class for the base modifications today (my mill isn't big enough to do it at home), and then this pops up in my feed on the way to class! Definitely subscribing :D

[@RobB_VK6ES]

Been a professional machinist for 40 years and in all that time I have refused to use the bolt circle function. For one, if you are doing an even number of holes the routine does not take advantage of the symmetry to minimise table movements and secondly, the only time I ever used the function like you I junked the part. I like to go back to basics and use simple trig to calculate coordinates. For a mill the Y offset is given by radius x sin of the hole's angular position and the X offset is given by radius x cos of the hole's angular position, assuming the center is 0,0. Simply apply any offset from your work piece origin to the calculated hole coordinates. Using this approach you can take advantage of the symmetry to firstly minimise the number of calculations and secondly minimise table movements. As for the spin indexer If you were to cut a vee way along with a round bar screwed to the base or use a key way and key into the base you could, in conjunction with the tee slots of the machine table eliminate the need to align the fixture for 90% of work pieces.

[@pauls5745]

I love the idea of adding a thrust bearing!

Very tidy update - well done.

[@woodscreekworkshop9939]

Thanks Dan,

[@LocoFabandMachineworks]

Nice work there. Mine had a bunch of slop in the spindle to housing so I had to split it and sighted the bore with 3 cap screws and rehone it. I haven’t fitted thrust washers yet so thanks very much for the listed part numbers 🙏

[@woodscreekworkshop9939]

Thank you!

[@rickhand8228]

Really interesting project. You do a very good job!

[@grahamsengineering.2532]

Hey Yuchol thanks for sharing. Great little mod and upgrade.

[@woodscreekworkshop9939]

Thanks Graham

[@seeigecannon]

Very good video. Something I did to my spindexer that you might want to consider is turning it into a sine plate type thing. I added a pair of V-grooves 4" apart (I think) on the bottom side of my spindexer and added a couple of 1/2" drill rods across it. This allows me to set fairly precise angles. There is very little holding force on the magnetic chuck on my surface grinder though. I get around that by building a cage of 1-2-3 blocks to help keep it from wondering. Also have to have very light cuts.

[@woodscreekworkshop9939]

Great idea, thanks!

[@jamesclark2372]

good job, I don't have a spindexer, yet, but I'm looking for one now.

[@woodscreekworkshop9939]

Thanks James

[@flatheadronsgarage7345]

[@travisboggus]

Yuchol, love your videos! Especially this one! Probably going to do something very similar. For the dust cover, I will likely make it where the o-ring holds it in place, not a set screw. Less friction in use and I think you could make it slightly smaller in diameter.

[@woodscreekworkshop9939]

Thank you 👍🏼

[@andyZ3500s]

Well thought out and nice craftsmanship.

[@woodscreekworkshop9939]

Thanks!

[@TomMakeHere]

Great work Yuchol. It looks slick! Also that new mic sounds great and I reckon it will work well with your workflow

[@woodscreekworkshop9939]

Thanks Tommy. It was rough going with the new mic. Lost some footages because I didn’t use it properly. So much learning...

[@andrewwilson8317]

I machined slots for removable tendons on mine to allow quick “ clocking” to the table of my milling machine, for those quick little jobs. Tenons a snug fit the Tee slots.

A $60 Spindexer is now a $Pricey grinding fixture. Great work.

[@woodscreekworkshop9939]

Thanks Vernon 🙏🏼

[@greggroos2271]

Very nice machining, and excellent video work. Even tho it was a lot of work to re-engineer, the Harig and Suburban tools cost hundreds to thousands more. Suburban actually sells a spin indexer more or less exactly like yours, for 15 times the price. I also have one of these, used 2 times, now buried in a drawer. Next time that thing comes out, it's getting a makeover.

[@mog5858]

projects breed projects one never know till he gets into a simple project how much you can learn. keep up the good work

[@woodscreekworkshop9939]

So true, thanks

[@GnosisMan50]

I thought you were going to make the dust cover out of plastic. Aside from that, you might want to consider using set screws with brass inserts to hold the hub. This way, you don't mar the spindle when you fasten the hub on it.

[@AWDJRforYouTube]

Great job sir, I did similar machining to mine years ago, did not do the installs and mods, just truing up all around for better accuracy and operation.

[@woodscreekworkshop9939]

Thanks!

On my DRO, I set the spindle to the center of the bolt circle physically and then put in 0,0 for the center coordinate. I don't think they are smart enough to go beyond that. Thanks for the video as always.

[@davemason6273]

You do of course need to be at the place you intend to be your zero reference when you zero the DRO! Nice job, very worthwhile upgrade.

[@howardosborne8647]

For what you class yourself as merely "a home shop machinist" this is a very skilfully delivered project. That is very nearly the ultimate spindexer. The only major improvement I can see here is to convert it to accept ER collets as well as the R8's. One of our UK suppliers (arceurotrade) supply there spindexer with this dual collet facility as standard. That dro issue is similar to what I experience with the Sino unit on my mill. I find if I want a set of holes around a circle pattern I have to add one extra hole. I find if I want,say,20 holes then entering 21 holes on the dro setup gives the right outcome. For a bolt pattern of six I enter 7 and all is good. I don't fully understand why but it works correct every time. I wonder if you had gone with the same 330 endcoordinate but set menu for 4 indexes would this have remedied your problem. Perhaps just give that a try and see.

[@woodscreekworkshop9939]

Thanks so much Howard for your kind words. I think the key is to triple check everything that DRO says 😆

[@waynemackenziesr5005]

That what a beautiful build (except the extra hole). I am inspired to do the same as soon as I figure out a project that will need one.

@@woodscreekworkshop9939 Well thanks to you(wife will be angry but I,m happy as a clam in mud) I dreamed up, err I mean came up with a use for one and it should arrive in the next week. Now I got to get a bore dial indicator of course since you did it that way and I like new tools😄
