The jig works nicely once you have it built. However, my low review rating is a direct reflection of the missing information. The downloadable plan is missing the handle cut-out diagram. I'm sure I could improvise and make something work, but I paid for a complete plan and a complete plan is what I expected. I think it should be included. I did a quick search for this plan on the web and I found a freebie to download. That free download had all the necessary information, including the missing handle cut-out diagram. My advise - search the web before purchasing. You may find what you are looking for.
It is what I was looking for.
I love making my own jigs and tools
Does the job, works great but soso plans
You must think this through, resolve conflicts (e.g. one hole is marked with one diameter on a diagram and a different diameter on another view), add missing features and solve problems that show the author clearly didn't make certain options before writing the instructions. As an example of the latter, the jig will have assemblies for various sized box joint teeth, each with a groove in which a rectangular solid (metal or hardwood)is epoxied and which holds the box joint cut to position the next one. However, since the assemblies are made from 1/2" thickness stock, how did the author make a groove and epoxy a 1/2" rectangular solid as he states in the plans - there is no stock left for a bottom to the groove and the remaining part of the assembly would be detached entirely. Also, the jig has a holddown for the assembly sizes not in use, since he planned it for 1/8", 1/4", 3/8" and 1/2" sizes. The jig also uses a backing board for each size, but the plan does not include a holddown for the backing boards that are not in use but which you probably want to add to the unit. The design requires that the backing board be notched, but that was seemingly added as an textual afterthought, not indicated on diagrams nor sized, yet the very first attempted use would make this obvious. In spite of the shortcomings of the plan and instructions, the jig is very helpful and powerful once completed.
