In the years I ran a job shop, I kept a lot of sheet lead, used for shower pans in plumbing, and placed under chuck jaws, and mill tables, to kill vibration. I also had boring bars that were drilled nearly all the way through, and filled with led shot, and a grease zerk installed as a plug. Dead as dead can be for vibration.

You could use poly bags and fill them with sand to help with that harmonic.

I love seeing these old, massive machines work. The precision seems amazing, given their size.

This was a two-fer. I learn from you and your commenters. There are YEARS of experience commenting. Thank you for the videos.

One of the things I noticed is that you employ all your senses when doing this kind of work, not just your eyes but also your ears and sense of touch. Others mentioned shot bags to kill vibration, I'll bet sand bags would dampen vibration, too. You should have some sand bags in you lighting kit, anyway. Thanks for another "boring" video.

That Lucas mill is a beast of a machine, I love seeing this old iron still being used to this day and producing close tolerance parts.

First time I've seen the Mrs. 😊

The length to width was quite a bit on those. A cheat I have learned from my set I use on my small bore bar is to drill and tap the tops on the back side and tie your two angles together at distance say a foot a part or so. That allows it to operate like a box and makes it much stiffer thus eliminating chatter. 😊

There are times you can or would need to use angle plates on a lathe, if you have a carriage with "T" slots. And you can do a lot of milling operations by using a cutter heard in the lathe and the cross slide or carriage to move the work.

There are no machines in my workshop where I need a long handled broom to clear the chips and have to clamber on the machine to set things up!😁 Nice job, and a beautiful finish!

Great video! Saw your name pop up in the comments over on Inheritance, listed you as right up there with them, and Cutting Edge. A great compliment!!!

This never gets old. I just wish I could get back into the shop and put my hands on those handles again. Thanks Josh.

Another way to cut down on the vibration is to attach a heavy weight at one or more places along the 'spine' of the part. Your big Vevor lifting magnet would be a good candidate, I suspect. The idea is to change the resonant frequency of the top of the part so that the whole thing can't 'ring' sympathetically with the other parts. For small parts I have just used a vise-grip, experimenting with placement to get a spot that stops the resonance.

To change the harmonic resonance try welding the two together and then machine them.

I have seen guys pull all but one insert making a sort of fly cutter. Takes longer but cuts out the vibration and leaves an amazing surface finish. It’s one of those things sometimes it works great and sometimes it doesn’t.

Hi Josh. Just a thought. If you had set both angle plates up beside each other. You could’ve used 2 squeeze clamps, one in spreader config to help eliminate chatter. Possibly also use the giant lead solder wire trick wrapped around the end mill arbor to change harmonics. Plus if you attached some stock in the slots, you could cut both plates together and they’d be indexed.

A thought- a 4x6 or 6x8 between the angles might further the vibration dampening. As you know far better than I, rigidity is essential in machining, and the opposed “square “ helped a lot. But metal transfers the vibrations of the inserts making contact with the edges of the plate, and wood should dampen the vibration rather than pass it along. Easy, and you probably have some shipping dunnage laying around the shop. I’ll bet you a coffee it really will improve the process and possibly help in future projects to increase feed rate and improve surface finish. What ya tink? 😂

Very nice job and excellent surface finish. Good that you did the bottom, too. It's too much setup for a compromise. Thanks for another fine video.

They came out beautiful and worked better than expected

To reduce vibration and chatter in that situation, I suggest you add mass on that triangle gusset, and clamp it there with rubber or similar between the clamp and your plate. This adds mass AND damping. The added mass changes the resonant frequency, and the damper suppresses vibrations if they are generated. This is what the shocks do in your vehicle suspension. What you did there was to increase rigidity which also changes the resonant frequency. Good work. I like your approach to problems and the way you find solutions.

Love the rapids on that machine. On mine, you have to shift 4 levers. --Doozer

Just a suggestion, Add shim stock as needed under the bolted down surface at setup, to halve the stock removal and lessen the spring in the weldment? Cutting down against the table was for sure the way to go.

Another job done right the first time! It was nice to see your line of thinking as you worked through the job. Thanks for sharing!

Bracing, get some allthread and couplers and tack a couple jack points in place at those extremes. Should still leave plenty of reach even running 2 pieces up to that big ear hanging out there to get your clamps in positions on the part. A couple ream holes near the bottom after you brought it all square (prefereably a half thou under your slot width and dowel pins to match) would make throwing these on and off the table any time a breeze. I was glad to see you finally use te other angle block as some bracing, but remember, the stiffer you can get setup before you slap that part up there, the happier she will be.

That took some experimentation, but it turned out very well. Thanks for the video keep on keeping on.

EXTREEMLY smart idea to angle the angle to the angle !!

Nice job Josh…. Enjoy watching your videos!

I love to see sizeable machining, and manual machines being used for jobs they should be doing. Perhaps a change in the machining order would give an even more aligned outcome. 1/ Machine the slotted face edge that goes against the table stops - so that it is machined reference. 2/ Machine the slotted face. 3/ Machine the last face. So it is machined the way it will be used and so will be as square as possible. There are basically four ways of removing vibration. Weight (e.g. lead) which lowers the resonant frequency (vibration point). Can be on the tool support or workpiece depending on what is vibrating. Stiffness of the workpiece (e.g. side support) which raises the resonant frequency. This could also be changes to the part (add ribs/welds etc) Change the frequency that the cutting induces. Changing the spindle speed as Josh did or changing the number of teeth (e.g. different cutter, removal of every second tip, all but one tip) Change the forces the cutting induces Changing the feed, depth of cut or both (as Josh does) The use of additional weight (lead strip and lead shot bags). The spindle on this machine is so stiff no change would occur even if lead strip was wound around it. That is the vibration was the workpiece moving, not the spindle moved. Adding mass to the angle plate would work, but the amount needed would be high and the method of mounting would be difficult and need to be added. As Josh showed very little needed to be done to remove the vibration and it was only occurring in one direction and was the workpiece moving, so the use of a side support was simple to do and had the desired effect.

Greetings Josh, wishing you a wonderful Easter Weekend, looks like a great episode, love the boring mill and the radial drill when you are using.......best wishes from Florida, Paul......

Good morning!

hi there very interesting, best to all john

when they would turn brake drums they had a strap they would put around the outside of the drum to knock down the noise .. I was thinking take a 2x4 board clamp it to the angle brace on both sides ,, the boards should knock down a lot of the noise if not all the noise ..

Morning Josh, Resonance harmonics caused from machining is always hard to overcome. Your approach to solving it in this particular project is innovative and educational. The camera work clearly explains what you did, why you did it and the outcomes of each attempt to remedy the problems encountered. The mark of a true master machinist. I have a little sign posted in my shop of an acronym that reminds me of things and helps when I face situations such as this. The sign simply says....SMEAC.....S= what is the situation, M=mission what am I trying to accomplish, E= execution, how and with what assets am I going to fix it, A=administration, how am I going to actually get it done, and C= command and control, how am I going make sure things are done the best i can do and in what order. Our dreaded snowstorm was a bust thank goodness, the bulk missed us and slammed Vermont instead, they got 15-24 inches. Only 4-6 inches here and cold temps following have ensured light fluffy stuff which will soon melt away as the temps soar into the 50s this week....your magical snow-blower has done its job again !!! Keep up the good work and if no one has said it, THANKS for bringing us along on the ride. Don

Nice....

Used to put sand bags or lead around vibrating parts. Sometimes that helps

10:48 You needed some diagonal bracing from the top to the sides.. 12:12 Told you so LoL

when it rings like a bell like that could you put a "C-clamp" on the web of your piece kind of replacing your hand to deadin the vibration, just something to change the harmonic of the piece ?? The other thought I had is using only half of your cutter vertically so your cutting force is downward into the table??

glad for you now almost 100k subs...i follows you since around 1.5k🙂👍👌

See I was thinking at your initial setup to put both plates facing the cutter and simple jack between them at the top. That way you can face mill them both in the same setup. I ran a Bullard about that size as the Lucas back when I was 19-20 and vaguely recall doing something similar.

Hi Josh I watched a guy turn some rotors and drums for automotive brakes, and he used a rubber strap to prevent the part singing while it was being machined. I wonder if you had clamped a piece of rubber to the web if that would have been enough to dampen the resonance? Anyway, you found a method that worked, which is all that really matters. Thanks for sharing this with us!

Good job on adding the second angle plate for stiffening. It really doesn’t take much to snuff out vibration in my experience, just very careful placement of struts or supports. I was thinking it’s a pity that horizontal doesn’t have a rotary table otherwise you could do it laying down, that type of mill is not common here in Australia, we normally have the rotary table type borer with a facing head built in.

You should have clamped aluim or wood too get rid of Is vibration,Ran a horizontal boring mill 7 years , I have run & set up job way too big for the machine but got it done,also lot of line boring for metal Fabricated gear boxes big ones size of a Toyota car lol

I was thinking if you added weight on the V portion you would dampen the vibration. You handled that with the other bracket...

I would have attached magnetic vices to the web for damping. Clamp any and every thing to the web..

Couple chain binders or even ratchet straps down on the diagonal would likely have stiffend that up

Nice work and video. Did you consider running an end mill down the ridge of the base plate to ensure the edge is vertical? You may have taken care of that when you made the angle plate originally. Again great job

I meant edge.

Surprised you didn't mill the edges after doing the first face. The rough edges used as a reference against your blocks almost certainly introduced some twist. Or were those already machine previously?

I would have tried milling all 4 corners only.then laid the part horizontally on the table,indicate it in. That way the edge would be solid all the way.

Next week is the next plate. It will go way better. I never had to assemble one, but I can imagine it would suck.

I thought the idea of wood wedges between the 2 angle plates would have helped dampen the chatter. I’ve also seen an inner tube pulling an oak beam into the back of the workpiece as a damper.

Yes, use the other angle plate to firm up the setup. How many times have you all done a finish cut, it's on size, everything is cool, and it chatters on you and woodpeckers up the surface? And on an expensive part like the angle plates. And the customer wants it today. Us machinists have to be greedy when it comes to rigid set ups.

You could also try setting that cutter off to the left so there is more downward cutting force than sideways with the teeth.

Milling the plates that high up from the table, without support, is akin to turning a shaft hanging out of a chuck with no center.

Just clamp a hunk of metal where you were putting your hand. That would change the natural frequency of you part and change the amount of vibration. You can also fab a damper on the spot by using some compliant material attached to the web (that's what you were doing with your hand). Bracing the part risks changing the shape and that will show up in the end product.

I did that 10 years ago. I remember lots of short welds and tweaking. Maintaining interpass temps, slow cooling. It was a process for sure,but well worth it.

How about bolting (or somehow attaching) a mass of of metal to the upper part of the gusset plate. That'll damp the vibrations.
