IH Gasket Repair help

Waitttt a minute, slow down there big boy. No one responds to you and you start going on a tirade. I'm saying tirade because thats what you doing. Your trying to trash IH for no reason, or maybe your a competitor, or maybe you are just Philbur. The simply fact is Gene has just said, out of all the mills he has sold, not one leaked oil. Your really trying to just find something wrong with the mill with no proof and just slander and its disgusting.

I see your 15-25 number over there, how do you know the bevel isn't in that range?? Are you basing your number on the measurements I said?? Someone who isn't even a machinists!!!!

Because now that would be a really stupid thing especially if you did work in this industry. Do you know how I took those measurements, lol?? I used a ruler, on a bevel!! so believe me when I say I was guesstimating!! I didn't even give you the hypotenuse, I gave you the height.

Now lets assume the stub was created properly because why shouldn't we!!!! when of the 100 or so mills Gene has sold not one has leaked. And if you want to include Aaron in that, what 1 out of hundreds literally!! And the one was fixed in about an hour! Both of those are near perfect percentages. So lets go to the most obvious mistake, 1mm is close to a 1/32, the ruler I used doesn't even have 32nd's let alone 64's. 1/2mm off in either of those numbers puts you smack in the middle of your 15-25 region and believe me I was rounding.

How can you based your arguments on measurements taken with a ruler that doesn't even have the precision your arguing over. Seriously, did you really work in this industry? So before you go one another rampage, why don't you actually buy a mill and do some measurements yourself. Or how about you take the trip over to IH and see what your bashing. But just coming in this forum for the purpose of trashing IH is very poor.

If the seal gets caught and the lip wants to rather fold over than expand and slide over the shaft, it is a sure sign that that chamfer is probably not right.

Dude, you have no idea what your talking about. I've said it several times, how do you proposed to get the spindle housing out of the mill head when its cast iron and part of the mill head? You've not replied. What your saying make no sense at all.

And we already know the stub wasn't the issue with mattinaustin's leak. Because if it was, the problem would not have been solved with a new seal and grease. Why can't you understand that?

[keitholivier]

You are such a dunce. Is that thing in MattAustin's hand not the seal carrier ? And how hard do you think it is to take that piece and slip it over the nose of the drive gear that is conveniently sitting on the top cover,which is lying on the top of the bench ?

You don't know how to use a lathe. Your head hurts and you get scared if you have to try to figure out what a specification means. And you can't measure to even 1/64th. Besides that you cant even do a bit of trig. I bet you have never designed anything that has ever been mass produced.

Your ownership of the IH mill proves that you have a bank account and a credit card. So has Britney Spears and she can afford a few more mills than you.

Ignorance CAN be cured but stupid is forever.....

And that is my LAST contribution to this thread. Rejoice !

I already know the outer diameter of the stub, I know the inner diameter of the seal because I just brought it. All putting the together these two outside of the mill, where the plate isn't rigidly attached to anything and the top isn't attached to head will show is that the seal is sized right for the stub. It shows nothing about alignment inside the mill, you've just shown nothing. In fact I just did what you said downstairs and it showed me nothing new.

And what is your point? You want to do this check, which proves nothing but you can order the right products, to mess around with something that has 0% failure rate with Gene.

Gene just said in a few post ago that this has nothing to do with anything. Yet your still talking about something and throwing insults. You can't prove anything so you've just resorted to blatant name-calling with no substance. Good your not posting here anymore, move on troll!

How far did you tighten the grub screws when you put them back on? Are they rubbing against the sleeve? Would the spring have anything to do with it? I was thinking it wouldn't but I realized that we might not tighten it back down as hard as the manufacturer does. Thanks.

I am not sure if the backlash in the quill (I assume that is what the bouncing is from) is any different than before the seal replacement. It seems like it is worse, but I didn't really spend enough time before hand with the mill to really feel like I am being objective about it. I really tightened the spring to make sure that wasn't the problem...and it wasn't.

I spoke with Gene about this problem (who was speaking with Aaron) and we did try changing the phase of the plate on the left side of the mill that holds the horizontal shaft of the spindle pinion gear (I guess that is what it is). There are three bolts there and we theorized that it might be possible to rotate the plate and achieve a tighter interface to the spindle rack gear. However, I didn't notice any difference.

For now I don't do any plunge cutting without doing a lot of checking and re-checking to make sure the depth indicated on the fine control for the spindle is actually what the mill is cutting. For using a hole saw to cut thing wall tubing (fish mouth cute), I lower the mill head and lock the spindle for the cut...otherwise I get to much bouncing from the spindle which causes vibration that seems to be harder on the tool.

I'LL ADMIT TO SKIPPING AHEAD WITHOUT READING MOST OF THE ARGUING SO >>> From what i have gathered here, the spindle was removed from machine and seal replaced. I'll assume the nut and bearings were removed cleaned and reassembled, i'll assume the rest of it is up to par. So, with the locking mechanism snugged, and still moving with spindle, "read, grab long tool holder mounted in spindle and shake it". then i'd have to say remove spindle and apply more pre-load to the spindle bearings, if not properly loaded then shortly after assyemby and running in the bearings will be loose ! I experienced this as i had replaced bearings, and started loose and gradually tightened up one notch at a time till it stayed tight and no play yet spun easily. It ended up taking more than i would have considered to be suficient, my IH spindle is cooking up to 6,000 and has been doing so for sufficient hours to say that it is set and ready for the duration. I am running an angular contact on bottom and new replacement roller on the top. Initial failure was due to cast iron fine left in during assy which destroyed bearings and vaporized grease assuming of course there ever was any. as for the seal, mine was and is good. altho i did see lots of cast iron in gear box that could have easily eaten an otherwise good or properly assembled seal. I would have to suggest that the damaged seals were during assembly due to lack of cleaning and handling. With all that said, I'll go now and let you resume the arguing !

In reading this thread...

I wonder if there was anything about the method the mill was shipped that would allow the spindle workings to move under shock and their own weight, damaging the seals, and or castings.

Additionally, I would assume that a casting with minor porosity issues could be sealed by dissembling and degreasing the casting, masking off mating areas, and applying a coat of high temperature epoxy. The leak would have to be non-stress related.
