Find a mechanic with a set of easy outs. The broken fitting can easily be removed and replaced. New pillow bearings are usually pretty stiff at first. If the bearings you got have the collars with set screws, Put a piece of rod in the bearing and tighten the set screws. Clamp the end of the rod in a vise, take a firm grip on the bearing housing and turn it a few times. The bearing should loosen up. Don

Well, I managed to get the threaded brass part out of the pillow block housing, I just stuck a tapered flat head screwdriver in the hole and it backed out easily. I removed one from another pillow block bearing I had laying around and inserted it in place of the broken one, it fit just fine. I have a short 5/8" shaft, so I inserted it into the hole of the bearing, and tightened the set screws on the collar to lock it onto the shaft, then I took my 1/3HP 1725RPM motor and connected the shaft directly to it via a shaft coupler, and then after taking the grease gun and lubing up the bearing, I proceeded to turn on the motor, to see if I could loosen up the bearing. Even with the lubrication, after about 30 seconds, the bearing was too hot to touch. I let it cool down, and it was harder to turn then before. I then tried the motor again, and this time it heated up quicker. I think there's definitely something wrong with this bearing! The other one is fine, turns easily, doesn't heat up, even without any lubrication, it stays nice and cool, no friction at all. I think they shipped me a bum bearing. It seems awfully weird that the bearing with the broken grease nipple is also the frozen one doesn't it? I emailed them yesterday, still haven't had a reply. Geesh, what next. Also, Kev, (cpdad) I've emailed you a couple times directly, but didn't get a response, I have not received the shafts yet, and when I tracked the package via the UPS tracking number you gave to me, it says that the package was received and signed for by someone named "Bradley", in GEORGIA! As you know, I'm in Nova Scotia Canada, I sure hope you just gave me the wrong tracking number! Things don't seem to be going that smoothly!

Well, I'm still slowly plugging away at this, it's not looking so pretty yet, and probably won't until it is all assembled and the final coat of paint is applied to it. I decided to mount the motor on the back, it's much easier than on the bottom, and the way the bearings are mounted when mounted on the back make the wheels fit better, everything just lines up better when mounted that way. The hole in the bottom where the belt would have gone isn't an issue, as a heavy duty try will be covering all of that. I've also coated the inside of the machine, (on top of the epoxy marine paint..LOL) with an asphalt coating originally made for coating the rocker panels on your vehicle, to guard against rust from salt, and to insulate against vibration. It dries hard, and is yet flexible, so it's a great choice for sealing something like this, even though a pan will be put on top of it. One just can't ever "seal" things enough when it comes to this kind of thing, I found that out the hard way previously. The bearings are just kinda "sitting there", just to show the new position they will be properly mounted in later on using the 2 mounting bars that are shown in the pic below. They are only temporarily bolted on there just so that I could measure things, and will be removed and mounted "properly" later. I do hope my shaft actually "arrives", cpdad (Kev), if your out there, can you please give me a shout back, as your not replying to my emails, posts here, or PM's, and I need to find out why the shaft UPS delivery confirmation shows delivered to GEORGIA instead of HERE! Thanks! Chris Bearings temporarily mounted to show new mounting position: Below, bearing mounting bars, not bad for a hacksaw and a hand drill!...LOL Below, 1st coat of asphalt sealant: The machine thus far, still nothing mounted to it, but will be soon! Below, the broken bearing, still never heard back from the bearing store, and I'm not calling there long distance from Canada! This one is fixed, I'm more concerned about the seized up one!

cooknet, I don't want to hurt your feelers, but if I was on my honeymoon, I wouldn't call/email/blog or have contact with anyone I know for a couple of weeks ;D ;D ;D ;D
I got my fingers crossed for ya that he just got the tracking # wrong and it's just stuck in your Canadian custom's "in box".

I sure hope so Joe, I hate feeling like I'm harassing someone who is trying SO hard to help me out! I still cannot believe how kind that was of Kev to do that for me! It would just suck if after all of that something happened to the shipment!! Chris

I tried to order belts for my lapidary machines today, and "thought" I was successful, it took my order, and said they would ship today.
Then, I just got this email from them, stating that they won't ship to me because I'm a Canadian
I'm getting SO tired of being discriminated against because I'm a Canadian. I CONSTANTLY ship my gemstones to the USA, and have NO issues whatsoever, and have many people i purchase regularly from in the USA, again, no problems.
I've tried to buy countless items lapidary items, but constantly get blown off just like this. I guess my money is crap or something.
David Ulam of McMaster-Carr Supply Co, you can kiss my #@$#@%!@
This is the reply I got from the company:
Thank you for your order. Unfortunately, due to the ever increasing complexity of United States export regulations, McMaster-Carr will only process orders from a few long-established customers in Canada. We sincerely regret any inconvenience this causes you.
Thank you,

Hi Kev, Thanks for getting back to me, I don't know what's going on either! I REALLY hope it didn't go to GEORGIA!! I'm not having very good luck lately, I keep getting blown off by companies left right and center, which is why I am "building" a cabbing machine myself, to begin with, as nobody would ship me an arbor, and now, I can't even buy parts for it without them either arriving broken, or people canceling my orders because I'm in Canada, it just sucks. Geesh. If this shaft went missing, it would just be the icing on the cake. Anyhow, I "am" getting there, slowly but surely. Here are a couple of pics so far, still needs alot of work, being ill like I am makes the going slow, especially without all the right fancy tools, just basic hand tools, makes things SO much harder, and not as pretty, but I guess one can only do the best he can with what he has! Lemme know what you find out about the shaft, SO sorry to bother you during your wedding period!! I hope things go GREAT at your wedding!! Chris

I realized by reading this thread back again that I missed Dr Joe's post about hurting my feelings, and that I should be more sensitive to cpdad's wedding situation, he is absolutely RIGHT! I just wanted to apologize to cpdad, if I seemed insensitive to your situation at all, I REALLY didn't mean to! Part of having a brain injury is not being able to see how others may be perceiving you, and how you may come across the wrong way. I don't blame Kev for not wanting to deal with this situation at all during his wedding vacation, I only wanted to inform him of the issue, and really, I was most in a hurry to receive this parcel as it had cpdad's return mailing address, and I intended on sending him a wedding gift, both to show my appreciation for all he's done for me, and also just to wish him well in his new marriage! So, once again, I'm VERY sorry if I came across the wrong way, I hope I didn't appear selfish or anything Kev, and I don't want anyone here to think bad of me in any way, it's just my usual stupidity in not fully remembering the "whole situation", due to my memory issues I guess. This is a VERY important time for you, so don't worry about me, deal with it when you get back, and have a great time! Take care! Chris

Just wondering if anyone out there can give me a hand with the bearings and the belt. I connected it all up to a motor today, just to see if it was aligned properly, which I'm hoping it is, I have a V-belt, and the appropriate pulleys connected to a 1/2HP 1725RPM motor, the usual thing, and the pulleys are almost the same size, the one on the motor just a tad bit smaller, but I'm not sure if i have the belt tensioned properly or not. I don't rally have any experience aligning and tightening the heavy rubber V-belts, as I've always had machines that have those clear soft urethane rubber round belts, that are silent and very nice compared to these black rubber V-belts. Those are the belts I just tried to purchase but was rejected as they wouldn't ship to Canada. I'll have to find another source for them that WILL ship them to me, but in the mean time, I just want to get this thing up and running to the point where it will be ready for the new shaft when it arrives (I hope) and I can just slide out the short temp one, and slide in the real one that will be used in the machine. I have not injected any lubricant into the bearings yet, and it could be the WHOLE problem, I don't have a grease gun yet, perhaps someone might recommend what kind of lubricant to inject into these bearings. Is that why they are getting HOT right now? I only ran it for about 2 minutes, just to see if the thing was aligned, but that's another issue, the belt seems to be getting hot also, and the motor has some vibration , it seems to "bump" around a bit, now that it is connected to the machine, when it is not connected it is TOTALLY silent, very quiet compared to the others i have actually. I'm just wondering if I have it tensioned right, as I loosened it up to the point where I could grab the belt and it has some up and down play to it (while not running obviously..LOL). I'm pretty sure it is aligned right, and not twisted to the left or right, I'm pretty sure the motor is square and all that is ok. Is it just the nature of these belts to be giving that much vibration like that? There is NO vibration in the bearings, shaft or any of that, it seems to just be at the motor, and it actually is causing the whole machine to slightly vibrate, to the point where it does not feel right anyhow. Am i just being stupid in that it's obviously getting hot as there is no lube in the bearings yet? To me, it seems like the pulley on the shaft of the bearings is getting hot with friction of the belt, and that the bearings are heating up due to the heat transferring from the pulley, to the shaft, to the bearings, as the pulley is hotter than the bearings. I certainly can't run it like that! What do you think I'm doing wrong besides the obvious of not lubricating the bearings yet? Chris

Man, get some grease in those bearings, before you burn them up. That's probably where the heat in your shaft and belt is coming from. If you have room to put a straight edge on the side of one pulley, it should lay flat against the side of the other pulley. You should be able to push down on the center of the belt and get about 1/2" deflection. Where have you found the round urethane belts, and do they make custom sizes ? I need new belts for my little sphere machine, and can't find them anywhere. Oh, if your belt is too loose, that could be causing the motor to seem to vibrate. Also, are both of your pulleys the same inside width ? If the belt is too loose, it may try to climb out of the pulleys. Don

HiDon, thanks for the info! I know it is stupid of me to run the bearings with no lube in them, that's why I ONLY did so for about 2 minutes max. So what kind of lubricant should I inject into them with the grease gun I still have to purchase? Some kind of lithium grease or something? I'm not going to run it again until I lubricate it properly, and I need to know what to lubricate with before I proceed any further. I've got about 1/2" deflection, but how hard should you have to push that belt to get that much wiggle? I'll have to check the inside of the pully's, as far as i know they are both identical, but it makes sense to check it. I think a belt with more grip and less tension wold fix this, as I'm kinda thinking this whole thing is caused somehow by that V-belt. I tried a different belt, same "A" belt, same size, different manufacturer, same result. I'm quite sure the pulleys are aligned, but what troubles me is that the actual motor mount that is fitted to the motor itself "wiggles" as it vibrates, i can see the whole motor moving slightly, and the movement is in the mount itself, it's almost like the mount is not made of thick enough metal. If this persists, I'm pulling that motor and putting one on there with a heavier base, even though that motor is slightly noisier, but not bad or anything. Like i said, this motor is TOTALLY silent when off the machine, but ON the machine it's noisy as heck, weird. I wonder if it's a bearing thing in the actual motor even? Guess all I can do to troubleshoot is change the motor and change the belt with a new one, such as the Urethane solid core Round 3/8" Belting I plan to use for this and the faceting machine that I am also building. I hope it is heavy enough, it was recommended to me by a pro who builds faceting machines for use on the faceting machine I'm building, because that 3/8" size apparently fits perfectly into the shape of a V-groove belt pulley and will replace a V-belt, i just hope it is tough enough for the "cabbing" machine also. I'm currently conversing with a company located at www.ebelting.com as the person who referred me to them that supplies them with their belts, (Dura-Belt, Inc) says that they will ship to Canada. I don't see the product sold by the foot, unless I'm reading their page wrong, so I'm awaiting an email inquiry i just sent out recommending how to buy it by the foot so I can make my own belts by heating the ends and attaching it together, or by using the hollow tubing and the connectors that are meant for that material. The belting is located here: ebelting.com/index.php?main_page=product_info&products_id=29:8a5a2f2e7fd659b47e6ff88899ef167aI think this is the right stuff! Chris

It looks like the belt goes to the side viewed from the bearing side. Could be just the picture. If not alligned the belt will run hotter and wear faster. Most bearings are shipped 2/3 full and need about one squirt with a standard grease gun. If the bearing seal swells it is full. If you grease until grease runs out you basically have opened the seals allowing dirt, etc. to enter the bearing.

Thanks John, I'll run to the store and get a grease gun tomorrow, I forgot I'd need one, duh. what KIND of lubricant should I use to lubricate them though?? That belt that is on there is a A22 4L-240, I yanked it off and also replaced the pulley on the motor with a slightly different one that looks more "V" shaped, as opposed to the one that was on there that looked a bit more "square" shaped, and put on a A25 4L-270 belt, that other one was way too short, not enough room to even open up the motor mount on the back to even tighten it, I had about 10mm of play! This should make it alot more comfortable to adjust I think, well I hope anyhow! I really do think that those Urethane solid core Round 3/8" are the answer, but in the mean time, there really is no reason I can't get this to work with a "V" belt, even if it's not totally perfect or ideal, it should still at least "work" right! I at least know not to over lubricate a bearing by overfilling it, but I wasn't quite sure how much that would be, so thanks for clarifying the amount John! Chris

If you don't mind me asking...where are you getting your advice for the faceter from? I have an old Lee I am refurbishing.
Thanks,
