Tying Up a Jack Floor Loom: Essential Tips and Tricks

Ashford Jack Floor Loom (Photographer: Ashford Handicrafts Ltd)A jack floor loom is a cornerstone tool for weavers, known for its versatility and ease of use. It operates by lifting the shafts (harnesses) when the treadles are pressed, allowing for a wide variety of weaving patterns.This guide will explore the tie-up process using two popular jack looms: the Ashford Jack Loom and the Louet David 3 Loom. We'll provide a detailed step-by-step approach to ensure your weaving experience is efficient and enjoyable. Additionally, we'll discuss the importance of tying up your loom correctly, highlighting its impact on your weaving projects.Understanding the Jack Floor Loom MechanismBefore diving into the tie-up process, it's crucial to understand how a jack loom works. In a jack loom, each treadle is connected to one or more shafts, as indicated by a pattern or draft. Pressing a treadle lifts the shafts, directly connected to that treadle, creating a shed (the opening between raised and unraised warp threads) through which the weft thread is passed. This mechanism allows for diverse and complex weaving patterns. Ashford Jack Loom (Photographer: Ashford Handicrafts Ltd)Why Tying Up a Floor Loom is ImportantTying up a floor loom is a critical step in the weaving process. Proper tie-up ensures that your loom functions correctly, allowing you to produce even, consistent fabric. Here are some reasons that explain why you should ensure you have correctly tied up your floor loom before weaving: Accurate Pattern Weaving: Tie-up that corresponds accurately to a draft ensures that the correct shafts are raised when treadles are pressed, allowing for precise pattern replication. This accuracy is crucial for achieving desired designs, whether simple or intricate. Ease of Weaving: A well-tied loom provides smooth treadle operation and a clear shed, making the weaving process less physically demanding and more enjoyable. Prevention of Errors: Incorrect, or poor, tie-ups can lead to weaving mistakes such as uneven tension, skipped threads, and incorrect patterns. A correct tie-up reduces the risk of these errors, saving time and frustration. Loom Longevity: Regularly checking and maintaining your loom’s tie-up can prolong its life. Proper tie-up reduces strain on the loom’s components, preventing wear and damage over time. Ultimately, a well-executed tie-up sets the foundation for a successful and enjoyable weaving experience.Step-by-Step Tie-Up Guide to Tying Up a Jack Floor LoomYou need a few things to tie up your jack floor loom, such as a Texsolv cord or strong string and a pair of scissors. You may also use tie-up hooks or snap clips (optional) and maybe a pen and paper to note down your tie-up plan.Tying up the Louet David 3 loom (Source: Louet Looms)Step 1: Plan Your Tie-Up Pattern/Draft Selection: Decide on the weaving pattern you plan to use. Common patterns include plain weave, twill, and herringbone. Each pattern requires a specific tie-up arrangement. If you’re following a preexisting draft the tie up required will be within the pattern. This details which shafts are connected to which treadles (refer to the below diagram). Alternatively, if you’re creating your own draft you will need to determine the tie up required. For example, a basic twill pattern might have the following tie-up Treadle 1: Shafts 1 and 2 Treadle 2: Shafts 2 and 3 Treadle 3: Shafts 3 and 4 Treadle 4: Shafts 1 and 4 Diagram 1: A weaving draft with a description of the tie-up plan.Step 2: Prepare the loom Position the Loom: Ensure your loom is placed on a flat, stable surface. There must be enough space around the loom for easy access to all parts. Raise or lock the Shafts: Check that the shafts are in the correct starting position. They should all be level and not raised or lowered. Your loom may have a shaft blocking pin you can utilize to ensure the shafts don’t move around during this step. Step 3: Attach the Treadles to the ShaftsNote: The cutting and main adjustment of cords is only required the first time you use your loom or if repairs are needed. However you may be required to change the treadle tie up with each new draft/pattern.Using the Ashford Jack Loom: Cut the Texsolv Cord: Cut the lengths of the Texsolv cord to connect each treadle to the corresponding shafts. The length will depend on the height of your loom and the distance between the treadles and the shafts. Secure the Cord to the Treadles: Attach one end of the Texsolv cord to the eyelet or hole on the treadle. Ensure it is securely tied or fastened with a snap clip. Connect to the Shafts: Loop the other end of the Texsolv cord through the holes or eyelets on the corresponding shafts. For a secure tie-up, you can use a lark’s head knot or a Texsolv anchor pin. Adjust the Length: Adjust the length of the cords so that the shafts lift evenly when the treadles are pressed. This step might require some trial and error to achieve the perfect balance. Using the Louet David 3: Cut the Texsolv Cord: Similarly, cut lengths of the Texsolv cord to connect each treadle to the corresponding shafts. Connect to the Shafts: The Louet David 3 uses a slightly different system, where you loop one end of the Texsolv cord over the lamms which connect to the shafts. Secure the Cord to the Treadles: Attach one end of the Texsolv cord, which corresponds to a shaft, noted on your draft to the screws on the corresponding treadle of the Louet David 3. Adjust the Length: Adjust the cords to lift the shafts evenly. Ensure the cords are taut but not overly tight, allowing smooth treadle operation. Step 4: Test the Tie-Up Press the Treadles: Press each treadle one at a time and observe the movement of the shafts. Ensure that the correct shafts are lifted according to your tie-up plan. Check the Shed: With each treadle press, check the shed to make sure it is clear and wide enough for the shuttle to pass through without obstruction. Make Adjustments: If any shafts are not lifting correctly, recheck your tie-up plan and adjust the length of the Texsolv cords as needed. Step 5: Final Adjustments Smooth Operation: Once all the treadles and shafts are tied up and functioning correctly, test the loom by weaving a few rows. This practice run will help identify any issues with the tie-up. Fine-tune: Make any final adjustments to the tension of the Texsolv cords to ensure smooth and even shaft lifting. Common Tie-Up Issues and SolutionsEven with careful planning, you might encounter some issues during the tie-up process. Here are a few common problems and their solutions: Uneven Shafts: If the shafts do not lift evenly, check the length of the Texsolv cords. They should be of equal length for each shaft. Adjust as necessary. Sticky Treadles: If treadles are hard to press or do not return to their original position, ensure that the cords are not twisted or caught on other parts of the loom. Lubricating moving parts with a dry silicone spray can also help. Narrow Shed: If the shed is too narrow, check the overall tension of your warp threads. Uneven or too tight a tension can affect the shed size. Additionally, ensure that the Texsolv cords are not too short, preventing the shafts from lifting adequately. Pattern errors: If your pattern isn’t appearing as expected first check that you have tied up the shafts that are to be raised. If you have simply tied up the opposite shafts you may continue weaving but your pattern will appear on the underside as you weave. If there is a genuine error in treadling take your time to carefully check each treadle is connected to the correct shaft and make amendments as necessary. By addressing these common issues, you can ensure a smoother and more efficient weaving process, leading to higher-quality finished projects.Get Started on Jack Floor Loom WeavingTying up your jack floor loom is a crucial step in preparing for a successful weaving project.
