Benchcrafted may have sold out of their La Forge Royale Miter Jack kits, but the good news is that they still have the metal bits portion of the kit available for sale for $38 on their website. (Link here to Benchrafted’s Blog on this topic).
The other good news here is that Nick at Lake Erie Toolworks also has a few wooden vise screws and tapped nuts for this kit ready to go for those that may have interest here. The price is $150 for a wood screw & nut combination which also includes domestic shipping. If you have interest here, drop Nick an email quickly as their sure to go fast. email@example.com
