Topic tags/keywords: jig router clamp joining

While it’s cold out, I’m keeping myself busy drawing up a relatively complex multifunction jig. I have made a couple simpler ones, and have interest in several more, but I realized two things: 1. space is an issue for almost everyone including me and 2. these desired jigs all have many elements in common. So why not combine them?

I’d like to start a conversation about the notion, and so I will post four pictures of what I have so far. The first picture is the assembly of all the parts. Don’t let it intimidate you, because as you will see it isn’t going to be hard to build.

Here are some mortise set ups…

This is a set up for cutting equal or variable finger joints. A router with a top bearing pattern bit follows the fingers on both sides and has the capacity to cut all the joints for a box in two steps.

This is the setup potential for a double moxon vise, useful for layout, transfer, and cutting of dovetails. Notice it elevates the height to a comfortable distance above the work bench.

This is a compilation of ideas from many different sources. This is on my bucket list to build later this year after the potential of the design has been exploited as far as it can be taken. I know it won’t be for everyone, so don’t go all ballistic if you don’t like it. I’m very partial to well designed multifunction stuff that has the added bonus of using modular parts. In my shop are many modular items that serve me well around the shop and this uses some of them.
Let’s hear from you. I will eventually share the SU drawing at my website for you to download freely.

I definitely see the potential but like you mentioned, it may not be for everyone. The nice thing about a simple jig is that you can look at it and easily know how it works. But I can see how something with more than a couple adjustments could quickly become confusing if you’re not the person who designed it. I’m really looking forward to a video once you build it!

That makes my brain hurt.

Dan you are one of the most creative guys I know!
I’ll look forward to the SU drawing to peruse. I’m not sure I’ll have the mental nor skill to
capably implement it….

I think it would be easier to add on to the shop. :)

Very interesting – I will closely follow this thread.
Keep us posted!

Less brain power for sure!

Dan, this looks cool. I was just thinking the other night that I need to start making some jigs, and then that naturally flowed into, “where am I going to put all of these?”

I will be following along closely.

I suspect this probably would be easier to understand from watching it in action than from looking at specs/design plans. So I’m gonna go ahead and wait for you to build it and then put up a Youtube video :-).

LAWLs! The interaction is fun…thank you for it. This is one of those things that you don’t have to build all at once. You can start with the basic piece and add as you need it. It looks like, with that in mind, a builder might want to start with identifying what function is needed first. I’ll keep that in mind as I design and lay out instructions. I’ve made it BIG because my shop layout specs call for up to a 30” capacity on jigs like this. (Shop specs also call for a layout that can handle 10’ boards without moving anything (very much), etc, etc.) It can be made to any capacity one wants, within reason.
I imagine this to be primarily a hobbyist tool that they build themselves, not a commercial production. However, I’ve watched other ideas develop commercially where for $X you get the basic unit and for $10X dollars you get the “accessories”...

After studying the drawings, sleeping and looking at them again, I concluded I am still confused. But sometimes opening a box cereal can be a challenge for me. It is obvious you have put a lot of thought into the jig and I like the modular concept. I will be watching for future posts on this.

Perhaps these photos of a spring board prototype will help? This was built a while ago primarily to make repeatable mortises fast and easy for loose tenons. What may not be obvious is that the router edge guide is captive in the T-slot along the back, captive but slides freely side to side. Note also that I could not find a hinge that would keep the top edge of the tilting table even with the support table for the router, hence the quadrant style pivot whose center point is the edge of the tilting table.

Man! I just read the Porter Cable instruction manual (sort of— had to say that to keep reputation ya’ know) and now MY head hurts. The jig shown above will have nearly as many capabilities, and more in some areas, but I think it be a LOT simpler than the PC Omnijig! YMMV.

Here’s why I want the jig to be as big as it will be… It could almost justify its own tool stand.
