Lightning Lap Concave Faceting Mandrels

The LL-Mandrel Concave laps are used to polish enhanced concave facets on a design you've already cut on a gemstone. Several companies make concave faceting equipment. The two most notable are Polymetric and OMF-concave Faceting machines https://www.polymetricinc.com/products.htm, and Ultra Tec Fantasy Machines found at https://www.ultratec-facet.com/product/ultra-tec-fantasy-machine/,  https://www.ultratec-facet.com/

The advantage of the LL-Mandrel is in the ability to have just one lap to do all your work, just by cleaning and changing the polishing medium. Your angle-integrity is preserved, as there are no lap changes. Lightning Lap Natural Mandrels can be used with 1200 or finer grit diamond grit, spray or paste. You can also use waxes with oils, water or any kind of oxide polish.

Clean with alcohol and soap & water, before the next polish application. However, most users dedicate a lap to a single polish for fast polish changes; and to reduce polishing medium expense.

The Lightning Lap Mandrels are harder than cast iron and hold your polishing medium on the surface. They are very durable and should last for many years of service.

The mandrels can be purchased separately, or in sets of 4 or 6. Each #1 set of LL-Mandrels has one each of 13, 15, 17 and 19 mm diameter mandrels.  #2 set of Natural LL-Mandrels contains one each of 9, 11, 13, 15, 17 and 19 mm diameter mandrels. contact us.

Perfect Lightweight Sheets for Sensitive Hot sleepers
Color: Cream, Size: Queen
These sheets are soft, thin, and absolutely perfect for me. I have advanced CRPS and erythromelalgia, so I deal with severe nerve burning and heat sensitivity and cannot tolerate being overheated at all. I keep our AC between 56–64 degrees constantly, and since our studio is small, it usually stays around 61–63. These sheets have been a lifesaver for sleep. They are lightweight, breathable, and don’t trap heat, which helps me avoid extreme flare-ups and the intense burning pain I deal with. I'm bedridden so I need to be comfortable. They feel comfortable against my skin and don’t worsen my symptoms when I’m already in a lot of pain and look nice, wash nicely. For the price, they are also a great value. I’m genuinely grateful to have found something that helps me rest more comfortably. Will be buying more for us and gifts.

Great set of sheets
Color: Blue Pinstripe, Size: Twin
These microfiber sheets are incredibly soft and comfortable, especially for the price. I purchased the blue and white set for my daughter’s bed, and she loves them. The colors are bright and exactly as pictured. They fit the mattress well, don’t slip off the corners, and wash up nicely without pilling or fading. The brushed microfiber feels cozy and lightweight, making them great for year-round use. Overall, a great value and I would definitely buy another set.

Bold Colors, Great Quality, and an Amazing Price - Perfect Everyday Sheets
Color: Black, Size: Full
The Amazon Basics lightweight bed sheets have been such a great buy for my boys’ bedrooms. They come in a wide variety of colors, which made it easy to match each room’s style — and the colors stay bold and vibrant even after multiple washes, which honestly surprised me. The quality is excellent for the price. The fabric stays soft, doesn’t pill, and holds up well to frequent washing (a must in kids’ rooms!). Each set includes a fitted sheet, flat sheet, and two pillow shams, which makes the value even better — most sets at this price point don’t include that many pieces. Overall, these sheets are affordable, durable, colorful, and comfortable. I loved them enough to buy them in multiple colors, and they’ve held up beautifully. A fantastic budget-friendly choice for any household.

Incredible Value – Super Soft and Budget-Friendly!
Color: Emerald Green, Size: Full
Exceeded My Expectations I’ll be honest, I wasn't sure what to expect from the "Basics" line, but I am so glad I bought these. If you are looking for comfortable sheets without spending a fortune, these are a perfect choice. Why I Loved Them: • The Price: You really can't beat the price for what you get. It feels like a much more expensive set of sheets. • Quality & Feel: They are exactly as described—super soft and lightweight. They have a smooth, almost silky feel that makes them very comfortable to sleep in, especially if you tend to get warm at night. • Wrinkle-Free: I’ve washed them a few times now, and they come out of the dryer looking great. No aggressive wrinkling, which is a huge plus for me. • Great Fit: The pockets are deep enough that they don't pop off the corners of the mattress in the middle of the night. Final Verdict: The quality is great and the price is even better. I loved these so much I’m planning on getting another set for the guest room. Highly recommend!
