Lathe Face Plate Work

- In this video I set up a part on a lathe face plate in order to machine a hole. I have a number of them to do so I set up to allow for quick change out of parts. I ended up having to dial in each part but even with that I was able to get it down to about 6 minutes a part after a bit of practice. Thanks for watching.
Finally figured out you dialed in the indicator to 0 on that live center before using it, so you can measure the flex in between the setups. Incredible, thank you! Haven't seen that anywhere over the past 2 years i've been learning this stuff
Simple and repeatable.
Good job shop technique.
My take away was the lock plates for the clamp bolts and the set screw clamp adjuster.
For the home shopper you might have explained the balance weight, the single cut to get under the heat hardened cut line, the choice of which side against the plate, just explained more.
But, subbed, keep up the good work.
Thankyou for a great video. It has given me a very useful set of tips for turning out the cylinders of my locomotive. Great work, thanks again.
Nice Setup -- very creative . I like the short stiff boring bar setup . One cut and see you later .
That was my goal when I was setting up the clamps, keep the bar as short as possible. My original plan was to take two passes, a roughing and a finishing. The problem was the roughing pass put the tip of the insert right in the hard, laser cut surface and the insert tip would chip every second part. I changed to a single pass and one corner of the insert lasted for about about 30 parts. It also made for a faster cycle time. Thanks, Ken
@@hmw-ms3tx I agree ,getting the cutting tool under the laser cut surface was the ticket
I learned something. Thanks Sir great video.
enjoyed...simple/smart setup...tks for sharing
Thanks, Ken
simple but brilliant technique style, Funnily enough I had a heap of near identical parts some time back which I did vertically it in the mill with an annular cutter I'd like to think it was slightly faster but the Chinese plate we get here in Australia is often a mixed bag. On occasion you get some terrible hard spots which will really ruin your day when running HSS
This was very helpful, thanks. You didn't draw attention to it in the video, since it's just basic good (and required) practice, but the counterweight probably smoothed out any weird vibrations.
Good repeatable set up👍👍👍👍
Thanks Steve, Ken
Nice job Ken . Cheers .
Thanks Max, How is the new shop coming? A few weeks ago you left a comment saying your were bending reobar. Ken
@@hmw-ms3tx Ready to start the form work for the concrete , but the weather has come in & held me up for several days .
Your work is always interesting..not to focused on one thing. Plenty of variety
Keep the videos coming
Hope your staying busy 👍
Thanks. That's the nature of a jobbing shop, lots of variety. I wouldn't want it any other way. Ken
Very well explained. Thank you!!
How did you indicate that by using the body of the live center?
Thank you very much.
Nice to see a ring spanner used...the shifting spanner seems to be a us standard...
I had to look up ring spanner and shifting spanner as I had never heard those terms before. We call them box end wrenches and crescent wrenches (or sometimes all sixteenths). I try to use the proper size wrench (spanner) whenever possible. Ken

Well English grammar was lost overboard on the Mayflower lol.
There is a great trend in the US to use shifting spanners which is quite noticeable on youtube. Scale is used where we use ruler
6" rule 12" or a foot rule. Being a dive instructor for a long time the US use of dove would make us laugh. When an American used "dove" I would say I shot a few yesterday with my 12 gauge lol Here it is a grey bird that pops on your car lol
Do you use ground blocks to fit in the table slot so work can datum off them ?
Being Canadian I'm usually pretty good at British terminology. We have a bit of a bastardized Anglo-American language with remnants of empire/commonwealth and the constant barrage from south of our border. My grandmother and mom were both from England (Bradford) so I picked up a lot from them. One of my grandma's favourites, when she was mad at you, was 'shit in your hat'. They both left England in 1946 (my grandma was a war bride) so the stuff I learned from them is probably dated. It wasn't the Mayflower for them, it was the Queen Mary.
I have been wanting to make a set of blocks for the tee-slots on my mill but I haven't had time to get to that yet. Ken
That’s along the lines of what I was thinking.
Smart proses🚀🚀🚀
Nice to have a lathe with a large swing. That a 24" face plate?
Not quite, it's 20". The lathe can swing just under 21" so I bought as big a face plate as would fit. It doesn't get used a lot but is sometimes very handy. Ken
A face plste is an often overlooked piece of equipment, rarely used by the "famous" YT turners 😢
It might have slightly quickened set up if you had bolted something to engage the semicircle, but it worked fine as is.
I hadn't thought about it until you mentioned it but you're right, there aren't many videos of face plates being used. Engaging the semicircle would have probably positioned it as accurately as using the hole (they share a common axis) but the nice thing about using the hole is that the centre presses the part against the face plate so it won't fall off while a guy is fumbling around looking for the wrench that he previously set down just out of reach. Thanks, Ken
@@hmw-ms3tx i was thinking of using the tailcentre as well as the semivircle but as the saying goes ask a dozen machinists how to do something and get 15 answers. It is alwsys the end product that matters not how you got there.
How do you know how much counterweight to use
Hello John, Mostly it's just a guess. Put some on and then try it and see if the vibration goes down to an acceptable level. If not acceptable then adjust the amount and try again.
What's with the gloves
I get severe eczema on my hands from the coolant and cutting oils that I use. The gloves (and vaseline) keep it under control. Ken
Why not just shove a 1" drill through them loosely held on a drill or mill and let the drill find the centre of the existing hole ? I'd guess a 1" drill would give about 10 thou over in any case ;)
Absolutely bizarre way of working !
Yeah, I was thinking the same. A straight cylindrical inner surface is too little of a turning job. That part belongs on the table of a drill press, centered, clamped, then bore or ream or whatever.
