Frequently Asked Questions (FAQs):
1. What is the difference between the Osborne No. 84 and No. 86 leather splitters? The primary differences are the blade size and the depth adjustment mechanism. The No. 84 features a larger 8 inch blade and utilizes a movable twist handle with a locking stop for highly repeatable depth settings and easy lap skiving. The No. 86 features a smaller 6 inch blade and uses a different adjustment system.
2. How do I create a tapered skive with the No. 84 machine? To create a tapered skive, insert your leather strap, push the handle forward, and pull the leather towards you. As you pull the leather through the machine with one hand, gradually advance the handle forward with your free hand. This brings the blade closer to the roller, shaving the leather down to a smooth, tapered point.
3. What type of leather works best in this 8 inch splitting machine? This tool is exceptionally effective on firm, vegetable tanned leather, which is commonly used for belts, saddles, and straps. Soft, stretchy, or overly oily leathers like chrome tanned garment leather can sometimes bunch up or stretch when pulled against the blade, so firm temper leathers yield the absolute best skiving results.
4. Can the 8 inch hollow ground blade be sharpened or replaced? Yes, the blade is designed to be fully serviceable. It can be unscrewed and removed from the cast iron housing. You can then hone it yourself, send it out for professional sharpening, or purchase a brand new 8 inch replacement blade to install when necessary.
5. How do I safely mount this tool to my workbench? The heavy cast iron base of the splitter includes pre cast mounting holes. You must use heavy duty bolts or lag screws to secure the machine permanently to a thick, sturdy wooden workbench. Because you physically pull the leather through the blade with significant force, a secure mount is absolutely critical for both safety and accuracy.
