Benno - Excellent Video . It appears that my Ten Cent Burninshing Tool can make a Million Dollar difference. Like I always say " From Junk to Jewelry " I want you to know that I'm humble . I'm not just another pretty face . -- Jim
Thanks for these details tests. I have been aware of Jims product, nevertheless it is really helpful to see good comparisons of this type.
Some nice information you've gathered here. Does burnishing alter the size of the diameter? I've never done any burnishing work myself but I'd imagine it would alter the size, but not as expected. I'd guess that 15 thou you've moved in by isn't actually reducing the shaft diameter by that amount?
In my case with just the one pass of the burnishing tool, moved in 0.0075” on the radius, a.k.a. 0.015” on the diameter, I was getting fairly repeatable results of 0.0005” (half a thousandth) reduction in the diameter of the part.
@OgiveBC thanks for the reply. Excellent. It's not a drastic change, but it's still nice to be aware of
Indeed, I’ll have do a test with ten passes of the burnishing tool and see what happens…….
Benno - I'm getting excited ! It's like waiting for a child to be born . -- Jim
Hey Jim. It’s a boy!
I laughed out loud at this when you panned back. Fun video. That sheared off blade is impressive - very nice look at a typical material surface from that kind of break. Will you be repairing the blade and showing that?
@@StuartsShed I’m glad you caught that, I didn’t think I had to say anything in the video but, I’m not sure if it’s understood by all that there is a rather large part missing. Unfortunately we don’t do any work on propeller blades in house. I have not heard weather it is to be repaired either. That propeller could be over 40 years old with many repairs over the years, so it may become a lawn feature…….
@@OgiveBC That kind of "ignoring the elephant in the room" approach is just the kind of thing I like. Similarly, anyone who modifies their toolbox logo to "strap on" is alright by me.
Very nice work sir
As far as deep slotting goes we pretty much run whatever is handy, 2,3,4 flute etc. I find you have to run 4 flute shallower otherwise they blow up recutting chips, you can definitely tell a difference running two flute. I would run a fine tooth roughing end mill with air or coolant blast to clear chips and finish with a standard end mill. Since I started running CNC I run 4 flute full depth with a 10% step over & two flute for slotting up to 1/2D. That is pretty much max for full dia slotting for any endmill. I hate 316.
@@pvtimberfaller thanks for the info and ideas. I haven’t tried just the air blast in a long time, I should try that again. Also I haven’t spent enough time looking at roughing end mills in the catalog. Thanks again for the tips.
Benno - The inside of my Nose looks better than that Propeller . But my Nose dosen't vibrate . -- Jim
Try giving it a big blow!
4:00 re crossslide allignment - have a read of conneleys "machine tool reconditioning" or Slessengers "Testing machine tools" for an explanation - a pdf's available online
@@peterhadfield873 thanks for the suggestion, I have not read that. When I ever get a free moment I’ll look for that. Thanks again.
Thanks I leaned something
It moved 20 thou over 5" so 20/5=4 thou per inch
Coaxial indicators are one of the most fun set up tools there is.
Welcome, nice to have you aboard. Someone mentioned another similar but different indicator, see comment below. Has me very curious. Even the cheaper version I have is still pretty darn fun to set things up with. Lived without one for rather too long.
Geez…similar triangles .020/5 = x/34 X= (34/5) .020 X ~7(.020) Move tailstock .140” away from you No?
Get a roughing carbide endmill. Guhring makes a series with Firex coating that I really like. Then just have at least air blast on it, and do your slots in incremental step downs, 50-100 thou at a time depending on material and diameter. Once it's all roughed out, come back with a finishing endmill to make it nice and bring it to size.
Very interesting, I’ll look into that for sure. Always like trying something different. Hopefully I’ll try it soon and can make a video about it. Thanks for the info.
Benno - We are obviously wired differently . Before you finished your complicated explaination -- I had to take a mild seditive .What you are trying to accomplish is simple . The way you are going about it is complicated . I'm assuming that you want set up that shaft so you can turn it's entire length without any taper . Now I will open my Big Mouth . Using a Four Jaw Chuck - face off - Indicate and Center Drill for Concentricity. Put a Ball bearing Center in the Tail Stock . Position and lock the Tail Stock . Slide the shaft into the Ball Bearning Center . Go back to the Four Jaw Chuck and Indicate . Now both ends are running True . Indicate the total length of the shaft . The indicator will tell you that your Tailstock is out of line . Adjust the Tailstock so that it lines up . - Jim
@@TangentJim yup, that sounds fine. How one adjusts the tailstock to centreline is up to the individual, think of it like an ice cream parlour with many flavours. The method describe in my video is just one of many, a take it or leave it dish in the smorgasbord. I like it because I can generally get to perfection in three or less adjustments, generally two, but sometimes even one. The make an adjustment then sweep methods is fine too, but more like lawn darts or pin the tail on the donkey rather than a calculated adjustment. Thanks for watching and commenting.
Benno - Your saying is going to bite you . " Indicate or Assume " You used a Three Jaw Chuck and assumed that the shaft was running True . -- Jim
@@TangentJimtrue, ahh ,untrue, ahhh yup. Agreed. Give it a roll and indicate to verify and or take steps mitigate/correct. Good point.
Benno - You are a Bad Boy . You didn't follow your own advice . I'm giving you two demerits . -- Jim
So good to get videos from someone who knows what they are talking about instead of inexperienced amateurs (like me) posting videos showing or using wrong techniques. Innovation is good but basic, genuine experience and advice is invaluable.
Benno - You quickly fixed that Shit Show . I have one negative though . If the set screw backs off - the Brass piece can back out . I don't want to rain on your parade but that gives you something to think about. -- Jim
Wow thanks. Yes I was trying to set an angle on the compound slide using angle blocks. Thanks for taking the time to respond, it is very helpful for a beginner to hear "well none of these surfaces can be assumed to be true..." I deleted the comment because I decided what I was trying to do was a little foolish anyway. I was making a temporary balancing arbor for a harig grinder on a very old lathe that has not been trued at all. I got the thing made and it seems like it will be good to improve the balance on a grinding wheel or two.
Right on, always nice to hear of success. If you have time look up “Tangent Jim sine bar”, lots of great videos and ideas there. If you do a lot of that sort of thing buy one of them whenever you can afford it. In the mean time, until it shows up, you can set angles the trig/math/tear your hair out way, search “lathe compound setting”, there are a few good videos there for sure. I have a couple ideas to add, including the lack of reference edges on the machine, and dealing with poor machine set up, but that will have to wait until I can make a video on it. Have a great day.
Benno - I've adapter your phrase " Assumed vs Indicated " We both agree tha indicators tell the real story. Your video display of various Indicators and tips makes my boat float . Nice Job ! -- Jim
Thanks
Benno -- Here is my Tooth Fairy Scenario . If you have a 5C Collet Chuck - use instead of the 3 Jaw Chuck. Your Indicator will Thank You. --- Jim
Thanks Jim, don’t have collets for the lathe, Also the material is 1.5” dia. 4 jaw to the rescue? Not always worth the time to change chucks though………..not a space ship………haha. Maybe they used 3 jaw chucks at the space ship factory lately to make helium system flanges?
Benno -- Hey Jim " Nice Try but no Cigar " -- Jim
Great series of vids - some good refreshers for me. This one I particularly like because I hadn’t seen discussion of testing concentricity of a long shaft by turning two witness diameters. I like the approach - hope to try it at some point.
Stuart - This is not a contest - it's an exchange of ideas . It's about the easiest way to get there. We are looking for the path of least resistance . I'm sure that you have heard this line before . The shortest distance between two points is a straight line. We are looking for the straight line . -- Jim
@@TangentJim I understand. I apologize because I meant my comment to be a standalone note of appreciation for the video - and not a challenge to your excellent comment. I didn’t realize I was posting a reply to your comment - so apologies again. No argument intended. By the way, just subscribed to your channel also and am learning plenty from your content also.
Awesome shop dog!
316..tough stuff and stringy chips. Beautiful plus you timed the operations. I used to work in a plant that did stuff like this in addition to pressure vessel fabrication. They had a huge CNC burn table with oxy and plasma. Trepanning was not used as it took too long.
@@keithjurena9319 ya,a cnc cutting table would be nice, not at this place for a few years yet I’ll bet……we’re very “traditional” (stuck in the past). Thanks for the comment.
@@OgiveBC I hear you! That CNC burn table started out as an optical eye system which traced over drawings to make the cuts. It was a pantograph type system, I forget the scale
Very nice 👍👍
Benno - I've come up with a Plan "B" . Here is a step by step plan . Reverse the shaft in your Lathe Spindle . Stick out the side without square plate and indicate it in a 4 Jaw Chuck . Using your spider indicate the plate side . Now that both ends are running true . Center Drill the chuck side . Flip the shaft 180° - Re - indicate both sides again . Face and center drill the plate side . Now each end is square and running True . Now you are ready to for your steady rest . Does this make any sense to You ??? --- Jim
Yup, that could work for sure. I’d still indicate along the part if I was turning along then length, indicate vs. assume.
Benno - In my previous comment . I forgot to mention one thing . Place the faced and center drilled Plate into the Four Jaw Chuck and indicate gently . Now insert your ball bearing center into the center drilled hole of the small end - it should run dead true . Now tighten the Plate side and indicate - again. Both ends should run dead true. Now indicate the total length of the shaft -- to see exactly what you have . Between the indicated ends you will find out if the shaft is straight or bowed . Indicating will tell the true story .The indicator reading will dictate your next move. If need be -- you can cut a diameter to accept the steady rest. Does this make sense ??? -- Jim
I like the sled ...
Good information...Thanks
Benno - Assumed VS Indicated . Assumed is like Rolling the Dice . Indicating tells the real story . -- Jim
Benno - Very interesting Video - I learned a lot . Obviously , it's not your first Redeo . -- Jim
Clever, I'll have to remember that one
just wondering, why not chuck up in the 4 jaw, I think I saw one in the video, and just face off enough material to let the original slide under the carriage......love your videos, Paul in Florida.....
Yup, sure could be done, one consideration was the bolt recess on the stock one is not right in any dimension. Also on my new one I’ll round both opposite corners some day and it will just drop in anywhere. Don’t want to chop the corners on the stock one.
Awesome lathe extension on the big lathe, be great to see that one in action. What are typical tolerances in prop shaft and rudder shaft work?
The taper section of where the propeller mounts is pretty well plus/minus zero on the angle, ends up getting checked with Prussian blue and hand lapping if out. The small end of the taper is about plus 0.002, minus zero depending on the shaft size. The area of a shaft under a liner/wear sleeve is not so much critical on exact diameter but it has to be cylindrical, that is no taper for the liner length, say 2 to 3 feet. The ID of that heat shrink liner should be within a 0.001 end to end, preferably less. The OD of a liner is more a matter of pride than regulatory/rule. Say plus/minus 0.005” over the liner length not a big deal but always strive for less than about 0.001-0.002” so if anyone checks later they don’t think poorly of the last guy to work on it…………..if there is more than about 0.005 runout (depends on roller spacing) any anywhere due to a bend, it gets straightened.
I’m not new to indicating but the more you look the more you see. With an open mind there’s always something to learn. This is just to say I’d be interested to hear your thoughts on the matter regardless of the format.
Tap drill = nominal diameter - thread pitch Major diameter = minor diameter + thread pitch +/- … as the millwrights say, it’s not just good, it’s good enough. Pragmatism, then the pursing perfection 😅 But wow, that’s some fast work!
🎶 The headstock bone’s connected to the ram bone The ram bone’s connected to the turret bone The turret bone’s connected to the … main casting? 😅
Capsize a reef knot. Interesting, I noticed the similar structure to a full hitch some weeks ago stringing lacrosse sticks. I’m glad I found your channel.
Hahaha genuinely surprised, going off shine and colour I was expecting the left hand oring to be old, shows me to jump to conclusions!
Clever use of the id attachment!
A bit of a suddenly popular opinion on social media these days, but drilling with the carriage is my go to. Dro is useable with no contortions, and turning centers drill with the carriage/turret anyway. Only drawback is with multifix a Morse taper or large boring bar holder might be a few bucks, but powerfeed drilling? Yes please! I pretty much only use the tailstock for support these days. Caveat is a heavy carriage might not have the same sensitive feel for small drills. 🤷♂️ Maybe an obvious solution would be to mount up an 8” digital caliper to the tailstock quill and body casting? I’m not a huge fan of that idea but could be a way to get +/-.001” precision without needing to add or remove anything or combine readings from dro and dial indicator. Then again how often is it that drill depths are tight tolerance? A BP style mill has a spindle running in a quill is how I think about it.
You know, over 50 years ago, we had a less pretty version, which was made under the trade name "Diacator" from (I've just re-learned) "Swiss Instruments Limited" Still available, it isn't as pretty as yours, admittedly...
Interesting, never heard of it, just looked it up. Thanks for mentioning it.
Have not seen those before - a very interesting tool and a simple approach to the situation. Would not be too hard to make one if someone really wanted to.
@@StuartsShed Would not be too hard... First, let's take into account the "Hierarchy of accuracy" in measurement. You want to make something which indicates within reasonable accuracy to "tenths" (0.0001", or tenths of a thou... the equipment you make it upon, and with which you measure its components, must be made with components produced to considerably tighter tolerances) Many moons ago, we were led to believe a precision instrument components must be measured using a precision instrument that was made to limits a tenth of the width of those being produced... (it's not entirely true, but it's indicative of the necessity to measure precision instrument components with more accurate precision instruments...) The history of accurate measurement in engineering is an interesting one... We've been able to gauge (different, I know...) to millionths of an inch. Microns are 40 x a millionth of an inch... The history is fascinating... and yet, you'll find places where they have jig borers and standards departments with no temperature control... I knew a guy who worked at a place making parts for submarines, on a jig borer... "constant 20C, then?" I said... He had no fucking idea... worrying!
I had a camp chair with a missing rivet, each time you open it the leg comes out and you have to wrestle it back in, usually in the dark or after a few beers. Someone asked to borrow it so I put a new pop rivet in, must've taken me sixty seconds. It had been annoying me for a decade.
Have a good weekend. Who makes that green mill you have?
It is a “First” brand also might be known as “Long Chang”. It’s a Bridgeport clone with a NST 30 spindle. I kinda wish it was R8. Oh ya, and a Bridgeport.
You’re a philosopher. I very much liked your comments around what is known about the past, present and future states of a part. That is the very essence of reverse engineering. I shall work my way through your videos. Thank you.
Look forward to more

what is rudder stock is this for a boat rudder ?
Yes, it’s for a river style tug that has two propellers in fixed Kort nozzles and each propeller has two rudders aft of (behind) it.
