First off, Happy New Year! I hope you had a wonderful holiday season with friends and family. Debbi and I were able to celebrate with our parents, children and grand children. There is still nothing I enjoy more than watching our grandkids opening their presents.

Now that the new year is here we have hit the ground running, or sliding depending on the weather. We have already had one major winter storm this year and as far as I am concerned one is more than enough! While it's fun playing with the grand kids in the snow having to reschedule road jobs because the roads are bad is not!

I don't know about you but I am not a big fan of New Years Resolutions. I think resolutions are a set-up for failure because for the most part they are impossible to keep. I prefer to set yearly goals and try to beat them knowing that as long as I come close to them I am successful. This may be splitting hairs but I think there is a big difference between the two.

Our webmaster, Virginia has been hard at work updating and adding to our offerings. She has developed a new web site, www.hwmachinerepair.com This site is more informational in nature but has many links to our original site, www.machinerypartsdepot.com where you go to order parts online.

The one question I have gotten more than any so far this year is relating to gib replacement (should I or not?). So with that in mind, this months article is about helping you to decide if you should replace or just shim your gib. It also provides you with instructions on the procedure to shim or repair your current gib.

God Bless,

Barry, Debbi, John, Nicole, Heather and the rest of the gang.

Shim or Replace Gib

The gibs in you're mill are like fingerprints, every one of them is unique, every one of them is different. Bridgeport manufactured almost 300,000 knee mills and each mill has three gibs. The unfortunate truth is we cannot send you a replacement gib that will fit your machine. We can send you a new, oversize gib that will have to be flattened, scraped, hand fitted and grooved by you.

People call us for a new gib because; (1). There is no adjustment left. (2). The adjustment tang broke off. (3). The gib is broken. (4). The worst of all cases, "it's lost"

1) There is no adjustment left. For the sake of this article, let's assume the problem gib is the one between the Table and the Saddle (or the X-axis). The first thing you need to realize is that in fact, you have two problems, the gib is worn and the dove tail on the table is worn. The wear is in the middle of the table because that's where you use it all the time. If you remove your table, turned it upside down and put a straight edge on the table dove-tail, you will find the surface is concave by .003 to .004. If you turn your gib upside down on a surface plate, you will find the gib is crowned. In reality, the ends are worn away.

We can come to your shop and fit a new gib in 4 to 5 hours at a cost of $350.00 to $500.00 plus the cost of the gib and travel expenses. You can buy an oversize gib ($75.00), some blueing ($7.50), a scraping tool ($125.00) and have a hand at doing it yourself. Or, you can put a shim behind it.

Hard Rule Number (1): You always put the shim behind the gib, never, never ever put the shim on the front, or sliding surface

(Hard Rule Number

2): You must cut oil grooves in the shim to match the oil grooves in the back of your gib.of the quill.

GIB 2

OK, we're going to put a shim behind our worn gib, but how much shim? The taper on all three gibs is approximately .015 to .0155 per inch. So, if the gib is sticking out the opposite end by let's say a half an inch, you're going to start with a .007 shim. You can also start with a couple pieces of news paper which is about .003 thick.

Saturate the pieces with oil and stick them to the back side of the gib starting just beyond the slot where the adjusting screw fits.

Insert the gib, with the paper shims into the opening and see where it fits. If it will not go in far enough, remove one layer of paper and try it again. If it still will not adjust you obviously need to add another piece or two of paper. Once you have a good fit, cut your final shim from brass or stainless steel shim material. Cut the shim at least a half inch longer than the gib so you can fold at tab at the end.

I know I mentioned this earlier, but remember Hard Rule Number (2). Cut an opening in the shim that matches the oil groove on the back side of the gib (see below).

2).The adjustment tang broke off - call and we will discuss some ideas with you on how to fix it.

3).The gib is broken. Send us the gib and for several hundred dollars we will make you a new gib that is very close. You will still have to do some work on the gib to make it fit as it should.

4). The best we can do here is send you a good used gib but there is no way of knowing before had how it will fit but I am sure you will have to do some work (either scraping to make it smaller or shiming) to make it fit correctly.Give us a call at 800-285-5721 with any questions or concerns you have about your

I have been using Facebook for about a year to keep in touch with family and friends around the world but have recently seen many companies turn to this as an area of keeping in contact with customers. After looking into it I found that we could start a H&W Machine Repair & Rebuilding Inc. Facebook Page. The thing I like most about the page is the discussion board. If you have a questions we can answer them through the board. We will also use it to provide updates to our products and services and well as tips to help you keep your machinery running smoother.
