The manufacturers provide Castmaster with a steady supply of products, and they have a good cooperative relationship with each other.
We found that most of the Castmaster products are manufactured by CAST MASTERS and Cast Master. You should take everyting into consideration before buying the products, after all, it is not a small expenditure for most consumers. Castmaster products range in price from $249 to $249, and the average price of all the products is about $249. At present, Castmaster has 3 products for sale. When purchasing a product, price is the consumer's primary concern. C-series pins can be used from the bottom of the seat angle outward to the end of the crack.Castmaster is a brand in the jewelry casting supplies industry, offering a wide range of metal casting machines, metal casting machines, and grill burners to its customers.

Almost all repairs made to cylinder heads below the seat angle are made with L series stitching pins.

Special Spiralhook™ threads generate a drawing pressure that actually pulls the sides of a crack together and permanently locks them together. The tap can cut right into the side of the valve seat.Ī second type of stitching pin is the C-series, which draw cracks together, instead of spreading them apart. Many times repairs can be made to damaged aluminum heads with L4 aluminum stitching pins and the seats won't have to be removed. Lock-N-Stitch recommends stitching across cast iron intake and exhaust seats and re-machining the new seat right over the pin without installing a seat ring. The same holds true when you're fixing hard cast iron areas, such as valve seats. When extra material needs to be machined from the repaired surface you have to use a countersink to allow the pin to seat deeper. Where a perfect finish is needed, such as on a machined surface, the pin will crush into the surface and leave a perfect finish after a little machining.
It is not necessary for the tapered shoulder of the L series pin to evenly contact the surface and it usually won't. This leaves a small amount of the metal pin above the surface, so this needs to be ground off or machined off. When the L series pins are used they seal on the threads because the pin is bigger than the tapped hole.

The L series pins are popular for sealing cylinder heads because these pins seal on the threads making it possible to install them at steep angles. Lock-N-Stitch sells two different series of stitching pins. The sealing mechanism of the stitching pin is complex and has many metal-to-metal contact surfaces. As the stitching pin is torqued, a radial drawing force is created, pulling the two sides of the joint together. When the shoulder seats into its counterbore, the pressure angle of the pin comes into contact with the matching pressure angle on the underside of the tapered hole. No amount of pulling can make them separate. However, once the shoulder of the pin enters the hole. When you start screwing the stitching pin into the metal block, you can still pull the pieces apart. The metal block has two sections with a hole drilled at the seam between the two haves. The photos of the demonstration device that Silva gave me tell the story of metal stitching in a way we can all understand.
Descriptions and drawings show differences between the "old way" and the "new way" that results in a better quality repair.)

Professional machinists have been doing it for years, but stitching pins and other modern products make it easier and better than ever to do. (Section of the Lock-N-Stitch catalog that tells the history of metal stitching. A catalog that David Silva also gave me has material about the history of metal stitching. I demonstrated how the locking pin worked and Rex said, "Oh, that's just metal stitching you can do that with a plain bolt." He said that he had been stitching metal for years. In addition to showing how a C-Series stitching pin works, it makes a great little conversation piece in the restoration shop. This demonstration device is called a Lock-N-Stitch Castmaster C3 Demonstration View Block.
