A vending machine is a machine that dispenses merchandise when a customer deposits money, validated by a currency detector, sufficient to purchase the desired item (as opposed to a shop, where the presence of personnel is required for every purchase).

Usually, the machine may consist of a big rectangular-shaped box, standing up, that has a place to insert coins or bills into the machine.

Repair & Maintenance of the Bernina 830 Record Sewing Machine

#9 MOST COMMON PROBLEM:

OILING

There is a great deal of confusion as to whether, where, what with, and how much to oil Bernina machines. Your owner’s manual is indispensable in this regard. It not only tells you where and how much to oil, but also which oil to use.

First, a word about the oil itself. The safest oil to use is that which came with the machine, or that which can be purchased from a dealer. Bernina oil should say “Bernina” on the tube. If you have any doubts, for instance if you have purchased a used machine and the oil is suspect, it’s probably a good idea to throw that oil out and get some more. Bernina oil is very light in viscosity, and is almost clear.
The area that is most critical to oil is between the shuttle and the shuttle race. (See owners manual) Oil this about every second time the machine is used for any length of time. Just a half drop will do.
Over-oiling just makes a mess. It’s also a good idea to oil the pin on the shuttle that the bobbin case fits over, and a little on the bobbin case latch.

Having said the above about the type of oil, I will say that I personally have used Singer brand oil (found at any Wal-mart) with good results. “Three-in-One” oil or any kind of motor or vegetable oil should NOT be used on sewing machines at all. I have seen … Read more

How to Build a Bat Rolling Machine

One of the most searched areas in bat rolling is how to build a bat rolling machine.

There are several factors that go into building a bat roller. I will break this article out so you can make a n enlightened decision to whether you want to take on such an endeavor.

Here are some questions that need to be answered before you start a project.

  1. How the machine works
  2. Parts and Materials
  3. Cost
  4. Time

How the Machine Works:

Before any of these can be answered you will first need to decide on what type of a machine you are looking at.

  1. Perpendicular
    1. The bat is inserted 90 degrees to the rollers and can only roll 1 way.
  2. Parallel
    1. The bat is inserted from the sides along the plane of the rollers and the entire sweet spot can be rolled at once.

Most parallel machines can roll both ways, but a perpendicular machine can only roll 1. Also a perpendicular machine will leave flat spots in the bat and not roll the entire sweet spot.

We highly recommend a parallel machine.

The machines work by compressing the carbon fibers and laminates between rollers and then rolling the bat between the rollers. Primarily the sweet spot of the bats are the section you are targeting during the roll.

Material List

  1. The Shell
    1. Typically made of steel or aluminum
    2. Holds the guts of the machine
    3. Welded or screwed together
  2. Upper Carriage
    1. Holds the upper rollers
    2. Moves up and down
    3. Tolerances are tight
