planing lathe bed

This video is of the planing of a Harrison 5L 11" lathe bed. It is 66" long and was badly worn. I first set it up by indicating along the edges of the ways, but strangely, this surface did not match either the ways themselves or the pads for the feed gearbox and end of leadscrew support. Once I aligned the bed with this surface the ways came into reasonable alignment, as did the pads on the rear for the taper attachment.
The relationship between the vees and their flat way was measured before machining so that this dimension could be maintained. A small vee-block was placed inverted over the vee was used for this purpose.
Indicating all way surfaces beforehand gave me the amounts that needed to be removed and so I machined to these numbers. One exception was the inner surface of the carriage way. This had a gouge in it that I felt should be removed and so I went an extra 0.005". That moved the carriage out by 0.0035" which I felt was acceptable. Overall, the carriage ways moved downward by 0.020". That's quite a lot. Either the changegear box will need to be lowered and redoweled, or the carriage will need to be built up. I forgot to turn on the camera for the flat carriage way.

KZbin recommended this video, and several others, on lathe bed planing. I thought "What a boring topic", and moved on; But KZbin insisted I watch at least one, so reluctantly I did. I am now addicted. There is something wonderfully hypnotic about the process. I am inordinately pleased that I succumbed.

I remember the days we still had Shapers in high school machine shops . I remember the days when there was a high school machine shop, and a high school weld shop and a high school drafting department that had us make real orthographic projection drawings . There was an Electric shop as well as Automotive . All shops were different and concentrated on the different trades , and we picked the group that best represented what our interests were . Today its called manufacturing and nowhere nears what is needed in the different trades but rather general at best . We are not really gaining any grounds in our lack of trades portion of our education system . Its a bit sad to say the least , our lack of touch with the past .

[@Herr_Bone]

Back then we made mounting plates for all tool shops in the area. They were finished with a large radius in the chisel, the lateral feed was almost as large as the chisel width. These large plates we made were very popular because you could easily move a heavy tool by hand on these plates because it only rested on the high lines. It was difficult to grind the chisel, we used these S-shaped ones because they compensated for the chatter.

Nice! I guess you remove the same ammount on every direction so that overall dimensions are kept, but what about the bottom side of the bedways?, while watching the video I was thinking the saddle would now need the same ammount removed from it's bottom so that it could keep being able to grip the bedways from beneath, but no material was removed from that part that I could see?

@@reesacheson5577 I asked if you planed the bottom side of the bedways (where the "keeper plate" rides on). Because either I missed it, or is not shown in the video. If you didn't, the keeper plate might not be riding on a surface that would be parallel to the (new) bedways' surface?

[@4n2earth22]

Gettin' rubbed the right way. Nice.

[@Workshopfriend]

I really enjoyed seeing this planer in action. I wonder how you set the tool up for the current angle of the 'V's?

[@reesacheson5577]

That's a good question. But before answering I need to say that since spring, my mind functioning is questionable and I wrote that I would no longer be answering technical questions. But I think I can handle this one. The first step is to measure the angle of the ways. If the way is supposed to be 90 degrees, a quick way to check is to place a small Vee-Block inverted over an unworn portion of the way and feel its fit. Even small inaccuracies are detectable. This will tell you how close to 90 degrees the way is. An alternative is to swivel the planer head to match the angle and check it with an indicator - comparing to a 45 deg standard, such as a combination square set on the table. Then you can use trigonometry to find the angle. Sometimes the Vee angle is very close to 90, but not quite. Then I make a decision whether to copy the angle or just make it 45 each side. If I am also planing the carriage I usually opt for for the latter. In that way the headstock has to be scraped to fit, too. But that should be done anyway and so is of little consequence. I have sometimes suspected that a way has previously been scraped out-of-angle, and so I try to take that possibility into account. Now, for setting the tool. The first step is to set the planer slide vertical using an indicator against a square. Then install the flat-tool and set its edge parallel to the table. Do this using a tenths indicator, traversing the planer head until the indicator reads zero. The edge will now be perpendicular to the head travel. To set the angle, angle the head using the protractor markings. Mine is 10" diameter and, even with my eyes, it is relatively easy to be within 0.004" of the mark. That's 0.0458 degrees of error. (0.004 / 5.0 = 0.0008; atan .0008 = 0.0458) If the way surface being cut is 0.630 wide then that's an error of 0.0005", between the upper edge and the lower. (tan 0.04584 = 0.0008; 0.0008 * 0.630 = 0.0005") That seems acceptable. The mating surfaces will be scraped to fit. (See ratio note at end) Note that if the way is double the above width, or 1.25", then the error is double as well (0.001"). This is probably unacceptable and so as described next, indicating to a standard is preferable. If you would like to make it exactly 45 deg, then set the head using an indicator against a standard such as a combination square or a Vee-Block. Setting the head to *exactly* match the *way* is problematic because the cutting edge is perpendicular to the head travel. Perhaps an adjustable parallel could be used at the two extremes to check for parallelism of tool to way. A final check is to place a strip of 0.0015 brass shim stock between the tool and the way and bring the tool against the way. If the shim pivots at one edge the two do not match. Final note: in the above head angle error calculation, you could skip the trigonometry and just use a ratio. The degree markings on the head are at a 5" radius, so a 0.004" cord error would translate to a .0005" error on the 0.630 wide surface. (0.004 / 5.0 = 0.0008; 0.630 x 0.0008 = 0.000504") Also note that in the trigonometric example I use the tangent to obtain the angle. The tangent of an angle equals the opposite side divided by the adjacent side of a right triangle. The atan, or arc-tangent, of that division provides the angle. Rees

[@reesacheson5577]

zjg4gcvn asked: "What about the undersides of that machine?" Sorry but I cannot find this comment anywhere except in my KZbin email notification. I have spent an hour looking. I don't know how to use youtube or understand much of it and so that is likely the problem. But here is the answer. Hopefully zjg4gcvn will find it. I assume that you mean the two surfaces immediately under the ways: one to mount the rack and the other to keep the carriage from lifting at the back. If the lathe was setup properly these two surfaces seldom need planing, however it is important to measure to insure that this is the case. They must be parallel to the ways within a couple of thousandths. The rack surface has more leeway than the back one. And the accuracy of the back varies with the design of the lathe. Many have a set of spring washers under the bolt heads that allow the plate to lift somewhat. But the plate also runs with clearance and allowing up to 0.005 clearance seems perfectly acceptable to me. If by underside you were referring instead to the base of the bed, it should always be planed if it contains a central foot. This is explained in the video "Planing a Southbend Lathe Bed". If there is no central foot then the base only needs planing if there is a twist or is otherwise not planer. Rees

[@scada4321]

Question for Rees......With the loss of dimension on the ways, what's done to compensate for that loss on the saddle, the head and tailstock? Do the vee's on these items also have to be "trimmed"?

[@reesacheson5577]

The short answer is that planing the bed ways means that there must be a shift in the position of the lead screw to match the new position of the carriage apron. Usually this means that the feed gearbox and the leadscrew support have to be shimmed to hang lower beneath the ways. As for the Headstock and tailstock, what matters is that the spindles of each are parallel to the ways of the bed. If the mating surface of the headstock was made correctly to begin with, it should not need further attention. The tailstock may have worn due to its sliding action. Probably the wear has been merely even removal of material and so the result is that the tailstock spindle may be low with regard to the headstock but still parallel to the bedways and to the headstock spindle. But this has nothing to do with the material having been removed from the bed. In fact, with the bed now straight, the tailstock's relationship to the headstock should not change as the tailstock is slid along the bed. If the tailstock is low, the reason is due to its own wear and the solution is usually to place shims between the tailstock's base and the tailstock itself - the same junction which is used to adjust for taper. So that ought to answer your headstock and tailstock questions. As for the carriage, if the bed has been planed correctly, it's ways should be both level and of the correct width to match that of the carriage. If so, the carriage could then be scraped to exactly match the bed. If the carriage has not worn much this scraping should be removing less that 0.001" and so the task small. But the carriage is often worn, too. While the width should not have worn to be different than as manufactured, the ways are unlikely to be straight. In use, as abrasive "dirt" on the ways makes its way under the carriage ways, the ends of the carriage ways begin to wear more than the middle. This creates a "banana" shape which becomes a funnel to direct dirt on the ways further under the carriage ways. Once this occurs wear progresses very quickly. If the banana ways are too severe, the simplest solution is often to plane the carriage ways, as well. Planing the carriage has the added benefit if being able to insure that the direction of the carriage ways are perpendicular to the cross-slide ways. This perpendicularity is essential to being able to face a surface flat. Rees Acheson

[@brimstone260]

If you are taking something of the beds do you need to build up the carriage at all? Or is it fine just running a fraction lower than before?

[@reesacheson5577]

Your suspicion is correct. In all likelihood, between planing the bed and planing or just scraping the saddle, the saddle will have been lowered enough so that the leadscrew shafts will need to be lowered, too. Often this is easily done by shimming the changegear box and end-support down. Or, alternatively, the saddle can be builtup with an expoxy-like filler and machined to fit so that the leadscrews can remain where they are. Of course, the drop in the saddle will probably not be much lower than how it was running before the repair. And while this drop was probably creating excess wear in the apron, it does show that there is some leeway. -Rees

Ah, I seemed to have missed this one. Sorry. The ways of the lathe were not hardened. The tool is, indeed, carbide, but it still would not cut a hardened way with such a broad cut. There would be far too much tool pressure. Hardened ways would need to be ground. Rees Acheson

cool

[@numericalcreations5853]

How much would something like this cost?

[@roderos]

Can a scraper work like that on hardened ways? Or are these hardened after the shaping?

[@reesacheson5577]

The ways are not hardened, and will not be afterwards. Hardened ways cannot be planed like this, nor scraped. They must be ground. -Rees

[@roderos]

@@reesacheson5577 thank you for responding! Good to know. Does the hardening not warp the ways?

[@reesacheson5577]

@@roderos Good question. I have no experience with hardended ways. But I do not see how it is possible to flame or induction harden a long lathe bed without affecting straightness. Perhaps they are very lightly ground afterwards, but the setup for such a light cut must be painstaking. Or perhaps they estimate the bow and preload the bed when grinding so that it will come out straight after hardening. If anyone knows, please chime in. I find it baffling. --Rees

[@norolemodel2883]

Would love some explanation with it.

[@norolemodel2883]

Ann Acheson thanks! I would have been interested in watching how the machine is set up for this job, hear a little about the machine itself, what the problem was that caused the need for planing, and this verbally explained. I appreciate the efforts of making and sharing the video, but in this case it is reading the description for a few seconds and afterwards watching silently some forth and back on the machine for quite some time. Maybe you want to check out youtube channel Abom79? More tech talk, but educational as well.

I need this done to my Sheldon lathe. I don't think mine is as badly worn as this one though.

What I don't understand is: Why are there no way covers on the planer? I'd put a wound roll on each end and let the machine peel off one roll as the recoil spring retracts the other.

[@reesacheson5577]

Sorry for the delay. I have been pondering whether of not I am going to do any more planing. My mind is becoming increasingly foggy. I gave the shop to my son 5 years ago and he has expressed interest in planing ways. The shop is not his main job, though, and he is not sure he has the time. That said, I was not sure from your comment whether you were asking to have planing done, or merely wishing you had a planer to use. Rees

Tengo una pregunta: Quién planificó la primera maquina planificadora o sea como planifican las guias de la maquina mas grande que existe que no se puede planificar con otra maquina mayor porque no existe otra maquina mayor que lo haga ? O sea un guardian guarda , ese guardián es custodiado por otro de rango mayor y asi para arriba , pero quien guarda controla o custodia al primer guardian si es el mas alto o grande y por encima de el no hay ningun otro guardian ?

[@reesacheson5577]

Google Tanslate: "I have a question: Who planned the first planning machine, that is, how do they plan the guides of the largest machine that exists that cannot be planned with another larger machine because there is no other larger machine that can do it?" I have answered this question before and here is the answer I gave: How did they make the first planer? An accurate planer can be made by hand using a straight edge. Whatever tools that are at hand can be used to speed up the process, but one could do it with a chisel, file and scraper along with some measuring tools to keep things parallel and fitting. And a straight edge can be made by making three of them at once, scraping each to another in sequence until all are straight enough for the purpose. And once you have a planer, a small planer can be used to make a larger one by segmenting the bed and table, and scraping them together to make the fit straight, for example. Very long planers have segmented beds. Rees

[@turbothis]

what is the cost generally for this service?

[@reesacheson5577]

Cost is not easy to predict because there is always something unexpected that has to be dealt with. This bed took 7 hrs at a shop rate of $50/hr. The South Bend that I posted on 12/13/20 took 6 hrs. These were probably about average. Most of the time spent is for inspection, setup and figuring out what to do. Beds are almost always twisted or sagged and they are worn. It is important to position the bed so that a minimal amount of material is removed, and that is not necessarily exactly the position it was originally machined in. Rees

[@sparkplug1018]

Almost a shame to reassemble the lathe and cover that work up. Excellent work.

[@bogdan_n]

Yes, but then again, all the excellent work the lathe will do (again) will be a reminder of this excellent work.

[@KC9UDX]

It won't be covered up!

[@nealblackburn8628]

i thought those beds were induction hardend and had to be ground to restore the surface...something going on i don't understand

[@KC9UDX]

Couldn't you have used a carbide tool?

[@reesacheson5577]

@@KC9UDX My reply to Blackburn is gone, but I think you were asking why not use tungsten carbide as a tool. Well, the flat-tool I used for cutting the way surfaces in the video is tungsten carbide. While it is possible to get carbide to cut hardened iron, plunging such a broad tool would require too much pressure to penetrate. If it could be done at all then it would need to be done in the conventional manner with a pointed tool fed across the surface. Such a surface would then need grinding to get rid of the tool marks. The only way that I would attempt dealing with hardened ways would be to mount a grinder to the planer head. I have only done so once. Rees Acheson
