[IC] >100kg Jimei Acetate - June 2025

by Chad Sobodash, 03-22-2025, 10:40 PM

Item Description:

This Interest Check is for acetate sheets from Jimei, to see if there is enough interest to surpass 100kg. To choose colors, simply post here a list of your order by code, thickness, number of sheets, weight per sheet. All of this can be found on each product page on Jimei's website. For example:

UA3, 6.0mm, 2, 1.9kg
UF-0188, 4.0mm, 1, 0.64kg

Please note that you do not need to include a link to your acetate model, I have merely done it for convenience here.

Supplier Information:
Shenzhen Jimei New Material Co., Ltd. - Chinese acetate sheet supplier located in, you guessed it, Shenzhen.
https://www.jimei123.com/

Estimated Pricing:
If you have access to Jimei's pricing, you are welcome to use that to estimate your order. Anyone who does not can indicate they would like a quote, and I will respond by private message with your quote based on the web pricing. Jimei's acetate can range in price anywhere from $8-25/kg. I will manage the responsibility of total shipping cost by percentage of weight estimated based on Jimei's average weight data. For example, if you are responsible for 13% of the weight, you are responsible for 13% of the cost.

Timeline:
Anyone interested can indicate their pledge here, to confirm once the group purchase is opened. If we cannot meet or exceed 100kg of pledged purchases here, then I will still initiate a [GP] thread, and simply recalculate cost based on other shipping methods. I will close this Interest Check on April 30th, 2025. Ideally we'd have the orders completed and placed by May 7th, 2025. This will be my deadline to place the order, and payments will need to be arranged before then. Please note that any orders placed by the group for items that are out of stock will incur an additional 20 day lead time, which is why I've placed the delivery date around June.

Purpose:
Orders over 100kg greatly reduce shipping costs, particularly when split amongst the group. Upon reaching 100kg, price by sea freight immediately decreases to $3.50/kg, possibly as low as $2/kg.

Sticky: Group Purchasing Guidelines

by Chad Sobodash, 02-02-2025, 07:19 PM

Welcome to the Group Purchasing (GP) section of the Guild of American Spectacle Makers (GASM) forum. This space is dedicated to organizing bulk purchases of materials, tools, and components to help members save money and access otherwise hard-to-find items.

To ensure smooth and fair group purchases, please follow the guidelines and structure outlined below. These rules are designed to protect both buyers and organizers, and to maintain transparency and trust within the community.

1. What is a Group Purchase (GP)?
A Group Purchase (GP) is an organized effort where members pool their orders to buy items in bulk, often at a discounted price. GPs are typically used for:

Raw materials (e.g., acetate, titanium).
Tools and equipment (e.g., drivers, pattern cutters, frame warmers).
Components (e.g., hinges, rivets, screws, nose pads).

2. Roles in a Group Purchase

Organizer: The person who coordinates the GP, communicates with suppliers, and manages the process.
Participants: Members who join the GP by committing to purchase items.
Moderators: Forum staff who oversee GPs to ensure compliance with guidelines.

3. How to Start a Group Purchase
If you’d like to organize a GP, follow these steps:

Step 1: Interest Check (IC)

Create a new thread in the Group Purchasing section with the following format:
- Title:
  [IC] Item Name
  (e.g., [IC] Acetate Sheet).
- Content:
  - Item Description: Provide details about the item(s) being considered (e.g., material, size, color options).
  - Supplier Information: Name of the supplier and any relevant details (e.g., MOQ - Minimum Order Quantity).
  - Estimated Pricing: Rough cost per unit, including shipping and any fees.
  - Timeline: Proposed timeline for the GP (if known).
  - Purpose: Explain why this GP would benefit the community.
  - Questions for the Community: Ask for feedback (e.g., preferred colors, quantities, or alternative suppliers).

Step 2: Gauge Interest

Allow the community to provide feedback and express interest in the IC thread.
Use polls or ask participants to reply with the following:
- Quantity they might be interested in.
- Any additional suggestions or concerns.

Step 3: Finalize Details

Based on the feedback from the IC thread, finalize the details of the GP, including:
- Exact pricing.
- Payment methods.
- Shipping arrangements.
- Timeline.

Step 4: Launch the Group Purchase (GP)

Create a new thread in the Group Purchasing section with the following format:
- Title:
  [GP] Item Name - Estimated Timeline
  (e.g., [GP] Acetate Sheets - June 2024).
- Content:
  - Item Description: Provide finalized details about the item(s).
  - Supplier Information: Confirmed supplier and MOQ.
  - Pricing: Final cost per unit, including shipping and any fees.
  - Timeline: Commitment deadline, payment deadline, and estimated delivery date.
  - Payment Details: Payment methods accepted (e.g., PayPal, bank transfer) and deadlines.
  - Shipping: How items will be shipped (e.g., bulk shipping to a single address or individual shipping).
  - Risks: Any potential risks (e.g., delays, quality issues) and how they will be mitigated.

Step 5: Commitment

Participants should reply to the GP thread with:
- Quantity requested.
- Preferred payment method.
- Shipping address (unless otherwise sent by private message).

Step 6: Payment

Organizers should collect payments only after the GP has reached the MOQ and all details are finalized.
Provide clear instructions for payment and deadlines.

Step 7: Updates

Keep participants informed with regular updates (e.g., order confirmation, shipping status, delays). You may simply edit the thread and include the date of the update, for the sake of brevity.

Step 8: Delivery

Once the items arrive, organizers should distribute them to participants as agreed (e.g., bulk shipping to a single address or individual shipping).
Please note that Participants will be responsible for shipping costs, and best practice dictates to collect shipping costs once items arrive to the Organizer.

4. Rules for Organizers

Transparency: Provide clear and accurate information about the GP, including risks and timelines.
Communication: Post regular updates and respond to participant questions promptly.
Accountability: Handle funds responsibly and provide proof of transactions if requested.
No Profiteering: GPs should be organized for the benefit of the community, not for personal profit.

5. Rules for Participants

Commitment: Only join a GP if you are certain you can pay and follow through.
Patience: Understand that GPs can take time due to supplier delays or other issues.
Respect: Be courteous to organizers and other participants.

6. Dispute Resolution

If issues arise (e.g., delays, quality problems), participants should first contact the organizer.
If the issue cannot be resolved, contact the forum moderators for assistance.

7. Example IC and GP Threads

Item Description: 2mm thick acetate sheets in various colors (black, tortoiseshell, clear).
Supplier: AcetateCo, MOQ of 100 sheets.

Once this thread has received enough feedback to be considered an agreeable procedure to the community, it will be locked.

Buffalo Horn Bleaching & Dyeing

by Chad Sobodash, 02-02-2025, 05:40 PM

After some discussion with Scott Balestreri, I want to try my hand at dyeing buffalo horn. He told me that he had purchased a specific dye for horn, but couldn't recall from where.
My idea is that horn should be able to accept leather dye, but may need to be boiled in an alkali solution to prepare it to accept the dye. I'm going to try a solution of sodium hydroxide and distilled water and boil the horn at a low temperature, which apparently has a bleaching effect. I'll post results here later in the month, but if anyone has any tips please let me know.
I'm trying to get blonde horn to the point where it has a candy apple red color for a project I'm working on.

Share your work playlist or songs you rock out to here.

I'll go first. X Japan is my favorite band of all time, so my usual playlist for work is mostly them, Dir En Grey, Queen, or anything with some good overdrive solos.
