Willys Flat Head resurfacing

[@lironmtnranch4765]

In the 80s I worked on an old flathead Willy's that a female classmate picked up to drive cross country to college. The thing would get up to about 3,800 RPM then the valves would float. In top gear high range, this was at 54MPH. The gal made it all the way LA to Colorado before spinning off the road and scattering all her earthly possessions down a snowy embankment, amazingly not hurt.

[@steveegbert7429]

Very cool! I milled many, many heads and blocks on the same model mill. Great machine.

[@geosutube]

This comment from a guy who has actually used the machine in question is far more important than the comments of the wannabes who have not.

[@steveegbert7429]

Thank you geosutube. And yes to the others, you do have to be mindful about where you anchor and support the piece to be milled. Every model part is different. You need to have knowledge about how each one reacts to stresses, which is gained through experience. And for anyone wondering about the cutter wheel, it is dead flat and square with the spindle, but the carbide cutters are all set at slightly different heights so each takes a progressively bigger bite. Treated well, the cutter wheel will last for a decade of use or more.

[@BobSmith-xw1yw]

Storm 85b machines came with 2 adapters that clamped from outside of head to 2 head bolt holes with dowls thru head bolt holes. They bolted to fixture and you placed screw Jack on other side to level. Will guarantee pulling thru spark plugs holes bent the head. Been there, learned the hard way!!!

[@panther105]

Does my heart good and even makes me feel a little proud to see a guy doing the same operation he's probably done hundreds of times and do it flawlessly. Laborious setup like that teaches you how important learning how to use precise measuring tools really is. People have been commenting on how old the milling machine is and how they would have done it differently, but in the end what did you get - a perfectly leveled and surfaced head with the least amount of material taken off. Nice work, sir.....

[@maxwebster7572]

or you could just lay it on a Van Norman right side up, with 2 shims and clamp from the sides and hit the switch like every shop I've ever been in. That machine seems to be a poor setup with too many moving parts to be accurate.

[@gwharton68]

Back in 68-69 I had a 1943 MB Jeep and decided it needed a little more power. Had a local machine shop mill 0.125 inch off of the head. He used a large plate milling cutter that he said that he made himself on a vertical milling machine. The plate looked very similar to the one in the video. It didn't make much difference in the power level. It still didn't have much.

[@tomhutchins1046]

On a flat head when you mill the head it also hurts the breathing. (air flow) because it closes down the space between the valves and the cylinder bores.

[@taxicamel]

Definitely not many commenters know much about machining ....and "Watson's Wagons" doesn't seem to have a clue where he is. Jigging this head using a master level ......on a dirty corroded surface? The least that should be done is wire brush the surface and maybe use a cleaner. But a LEVEL???? DIAL INDICATE THE SURFACE. DIRECT READ EXACTLY HOW MUCH TO MOVE/ADJUST THE JACKS AND VERY QUICKLY CONFIRM DEAD-NUTS "LEVEL" FROM THE CUTTER HEAD OR FROM THE TABLE .....if you know the machine. Have these 14 bits been "jointed" to ensure the bit positioning is exactly the same for all the bits? At 7:42 it can be easily seen that only ONE bit is doing the majority of material removal. The evidence is the surface finish looking like a phonograph record ...only worse. Which bit or bits are actually cutting? The guy running the machine doesn't seem to care ....and the camera man obviously has no idea what he's looking at. Won't be able to see the surface finish once everything "looks" the same. Well, they think they know there aren't any cracks anywhere ....the checking was done in only one direction. YUP .....GET ER DONE!!! .

[@digiacomtech5589]

A very minor assumption is being made that the cutting head is not warped. That is, when they move the depth micrometer from one point to another on the cutting head, and measure down to the head, they could be introducing error if the cutting head is warped. Probably better to use a dial micrometer and swing the head across the surface being leveled.

Easy enough to mount an indicator and sweep the top of the cutting head when setting up the machine initially. Then you know it's straight. Fast and accurate to depth mike from then on. No need to bounce an indicator across the head surface every time.

[@digiacomtech5589]

@@johnk3606 ... Again, if I understand you, this method would induce inaccuracy as well ... and that is the whole point of my post ... reducing inaccuracy of measurement. If you are saying (and I could be totally wrong here) to mount the mag dial indicator on the engine part (head) being machined and then sweep or indicate to the the cutting head and/or the cutting teeth attached to it then you are again inducing error as the cutting head could be warped and/or the cutting teeth could be misaligned. Take note that the cutting teeth are all adjustable (up/down) for this exact reason. That is, when the teeth are mounted they are individually set to be the exact same height relative to the cutting surface ... not an exact distance from bottom of the cutting head. So placing the magnetic dial indicator on the cutting head and then sweeping the cutting head back and fort across the head being cut, checking various points on the head, will eliminate these errors as the point of reference (e.g. the mag base of the dial indicator) is never changes. Granted there could be errors in the machine turning the cutting head (misaligned, wobble, old bearings, etc.) but these are reduced by keeping the mag dial indicator at the same point on the head while measuring. The point is that (and as seen in the video) anytime you move to a new/different reference point (e.g. moving the depth gauge to a different point on the cutting head) you are NOT measuring the same thing any more. Ultimately it boils down to "How much accuracy is actually needed here?" As I am not an engine design engineer, machinist, or mechanic ... I can't speak to those tolerance requirements so my suggestions though more accurate ... might be excessive for the task at hand. Food for thought on your next measuring task to say the least ;)

Likely flatter than it ever was from the factory. Nicely done. Don't need coolant, really, when taking such a light pass. That cast wouldn't even have time to heat up enough to cause any damage.

Watson's Wagons - im not questioning his competence just the procedure. It is inconsistent with accepted industrial thought on clamping or securing a flat stock.

But if the process works, im all for it is all. i also understand the limits of the type of milling machine being used - a Storm Vulcan flycutter. I own and use the same.

[@WatsonsWagons]

James Kennedy head works perfectly

[@travelingkaspersworld4096]

Very interesting. Will they ever introduce a flexible material where the head would shape itself to the block?

[@commonnons3ns316]

Traveling Kaspers World Simple answer is... No. Flexible material is weak and when under pressures of combustion, would flex to relieve the pressure. That's why you have to have 2 perfectly matched surfaces that don't flex. The easiest surfaces to match are perfectly flat. Plastic is used in making intake manifolds and can flex to match surfaces but they don't have to withstand the abuse of constant combustion. So, no. I don't believe there's any material that is flexible and able stand up to combustion pressures and heat. Aluminum is a softer metal and had some flexibility but, it still has to be perfectly matched to the blocks surface or it will fail and fail much quicker than steel. It so flexible that it can easy warp by not properly torquing the head bolts and cause gasket failure, fairly quickly. I just can't see any metal being softer and more flexible than aluminum that could hold up to the extremes of an engine's combustion. Especially now with the horsepower that being generated by engine builders. If anything, engineers are designing engines with stronger materials and less tolerances to withstand higher compressions. Turbos, superchargers and the likes, have become commonplace amongst manufacturers and that means that engines have to last hundreds of thousands of miles without major failures. That means heat dissipation and cooling advancements over finding a material that can flex and still retain it's strength. So no. It's unlikely to look for flexible material to avoid having to be precise. Precision is way too easy to achieve with today's technology. Aluminum became a common engine building material for its ability to dissipate heat faster and it's obvious weight differences. It still doesn't have the strength of iron or steel but, it has other benefits that make it useful. Flexible is actually not a bonus at all. It has to be overcome to make it a viable engine building material. I just don't see anyone wasting their time developing a flexible material that's primary goal is to mold itself to imperfections of the manufacturing of an engine block or vise-versa. I'd say No. Not gonna happen.

Not flexible but history shows engines with the top combustion chamber solid to the bore but they were not that practical, also vw Beetle engines use no gasket just metal to metal

we had a wet water machine back in 70's and would spray water on head to cool surface

[@Stelios.Posantzis]

That's a scary looking piece of equipment - scary expensive that is. I still don't quite get why this machine is built the way it is, particularly why it is so complicated. I'd watched another video of the same process before but it's by watching this video that I realised how much of an art setting the head level is and how one goes about determining it is level. The possibility of distorting the head in the process of levelling it is yet another dimension of the problem. The discussion about the head buckling though made me think: how do you know the head is not buckled in the first place? How do you go about it if it is? Do you try to correct the buckling using the props? I realise this may be a very silly question but it just really baffles me.

[@WatsonsWagons]

Stelios Posantzis we put a machinist edge on the head and checked the surface with a feeler gauge. I wanted the head flat and these things do warp. Just posted another video getting the rest back from the shop.

[@Stelios.Posantzis]

Watson's Wagons : Thank you for this. My original posting was not clear: I'm baffled by the principle behind this operation, not the execution. My reasoning is: if the whole head is warped and just its face is flattened, won't that just shift the problem elsewhere? And to be perfectly clear, I'm thinking of the case of a modern engine and not a flathead. My concern is that, on a modern engine head, the valve seats and valve guides will still be misaligned at the end of this operation. Wouldn't that create a problem with the cam? For example, assuming that the head's warping causes uneven loads on the overhead cam bearings, won't these get worn and introduce play in the cam axis? Please excuse my ignorance if all this is complete nonsense.

[@basketofdeplorables4253]

Stelios Posantzis cam bores could be misaligned on an overhead cam engine. But that would be checked and fixed on a line boring machine. Seats and guide would also be machined true again, but in another operation as well.

[@Stelios.Posantzis]

basket of deplorables : Thank you for this info - I didn't know that.

[@jostouw4366]

The worst deformation would be in the small section between the bores where the head would deform or burn away leaving ridges from the gasket especially on alloy heads resurfacing smoothes the head and restores the seal

[@scrapwire1]

I ran one just like it 35 years ago in Houston, did years of heads in it, the warp in that head is normal, The bolts probably had little torque on them, just enough to keep it from shifting around during the cut, The wheel exerts very little pull on the head being cut.

Hi guys, can I add a comment, or ask a question. don't bite me If I`m wrong here, but you only have applied downward force in the centre 2 plug holes, would that not put distortion in the centre of the head when machining? or was it done that way for a reason.. thanks for the video anyway, it made me Interested enough to comment.. Thanks, Ivor from the UK.

deweys it's not about the equipment, it's about the operator. Why change what's not broken? The operator has probably been using that equipment for his entire career and has perfected the use of it. I trust someone using old style equipment and years upon years of experience, over someone with new equipment with way less experience. A machinist tools are worthless without the machinist that knows how to properly use them. Complicated is a relative term.
