Sewing machine stitches slanted-CB4500

[Crest]

Hello! I have a CB4500 and have been pleased with it overall but it stitches slanted. As I feed the leather through, I can’t feed it straight through. I have to feed it at a slightly slanted angle in order to stitch straight my stitch line. Has anyone had this issue and been able to fix it?

This is a machine type question so I moved your post to Leather Sewing Machines.

Perhaps you could add some more information.  What needle type and size are you using?  What thread size and type?  A picture would help visualize what you are describing.

The machine guys crystal balls haven't been working for several years, so they really need your help by providing adequate information.

@Crestare you saying it feeds the material through at an angle? Or does it feed a straight line and the stitches are at a slant to the line?

The latter is just a needle choice.

As @AlZilla mentioned above the needle tip shape type can give an angled stitch such as an LR which gives a saddle stitch look. A TRI point needle will give a straight stitch if that is what you want. If you are having to hold the job inward as you go you overcome this fairly well with a guide that is angled slightly closer at the back behind where the needle is. This video I ade some time back shows how you can pretty much set up a guide that does not require you to hold it at all.

Please look at the package that the needle came from and let us know the designation on the needle. For instance, a System 794 or 7x4 in Schmetz S Point, or a 4-sided Diamond, or 3-sided Tri point, or an LR or LL twisted wedge point. The first 3 give a straight stitch line, but with a different visual front to back length on top. The last two are made with a left or right twist on the tip of the needle.

While the needles can lay the thread differently based on their geometry, the only ones that might try to push the leather sideways are the LL and LR slanted wedges. Personally, I avoid slanted needles. My preferred needles either have a diamond or tri point, or an S point, which is an inline slicing wedge. If you sew a stitch line with each of these two types, using the same stitch length and tensions, The S point stitches will appear closer together and submerged, compared to the diamond shape needles. Then, there's always System 7x3 round point needles that poke a round hole and are made to sew fabric and synthetics, and create a straight stitch line with good visual appearance between the ends of the stitches.

Now that the needle geometry has been discussed, there is something mechanical that could cause the strip to move sideways as your sew. That is a misaligned or loose needle bar and inside foot mounting frame. Normally, this frame is installed with a minimum of sideways clearance to keep it sewing straight. If some impact knocks the frame alignment out, it may sew off the center line. Look to see if your machine has an L shaped bracket screwed on at the bottom of the moving frame that contains the needle and inside foot bars. If present, make sure it hasn't loosened or moved to the left and giving too much clearance to the moving frame, which might be called the "rock frame," or such.
