One brand new jig is brewing

 

Over the weekend I noticed the following at the Leigh web site — the R9PLUS dovetail and finger joint joinery system:

The R9 at LeighI want to try out this new jig!

Stay tuned for further details. The web site says “Coming soon!”  This is the first I have heard about the R9PLUS Joinery System. Among other features::

  • No jig adjustments
  • Joint fit is controlled by patented eBush
  • Works on your router table
  • or with a standalone router
  • Adjustable width
So, if I get it right, I will be able to use it as a stand-alone jig, to machine either finger joints or dovetails on boards ANY width. This, friends, is thinking out of the box!

 

What do YOU think about this new jig?

A balancing act

 

Joe in Colorado wrote, asking whether the cradle I built might tip toward one end or the other as it was picked up by the handles. I replied that the cradle is perfectly balanced, as I used the following balancing technique prior to cutting the handles on the sides:

Getting perfect balance on the cradle

The tool: a 1-inch dowel placed across the bottom of the cradle, and perpendicular to the sides. I was careful to measure the distances with a tape measure prior to balancing. Once perfectly balanced, I marked the pivot point with chalk, and used a square to transfer the balance point to the top side edges. Then I marked the handle openings, cut with a jig saw, and smoothed the handle openings with rasps and files.

Balancing this way requires that the cradle be ready, or close to ready for the finish. At this point the cradle was already glued up; I had cleaned up the joinery with hand planes to ensure the corners were nice and flat, and that all the surfaces were sanded.

Here are the handles, already shaped:

Shaped handles - handles at balance point

Why wait to this point?

The answer: Removing material from large surfaces such as the sides may throw the balance slightly toward one end or the other. Given precious cargo such as a newborn baby, improper balance is a risk not worth taking.

How would YOU do it?

  • Is there a better way to properly balance the cradle to mark the handles?
  • How would YOU have done it?

I would like to learn how you would have done it. Please leave a Comment below, or contact me via the Contact Form by clicking on my signature below.

Loaded for bear

 

As I go through the cleanup of the shop, I move around machines and equipment. This allows me to make room to relocate things; at the same time, I re-discover equipment that has been idle for a time.

For the last several months I have been making a lot of boxes with finger joints. I am in the middle of changing gears, so it was most appropriate that I picked up this box. I opened it with trepidation, only to find some good friends:

Dovetail router bit kit

This set of bits has served me well. I bought it from Highland Woodworking in the (very) early 2000s, and have made innumerable boxes with the various bits. The boxes have featured dovetails in just about all varieties: Through dovetails and half-blind, and also end-on-end dovetails,  and inlaid dovetails. This makes me wonder:  How many more boxes I can make with the same bits?

How about YOU?

I would love to hear from you:

  • Do you machine-cut the dovetails for your projects?
  • Do you make a lot of boxes?
  • Or do you prefer to hand-cut dovetails for your projects?
  • What is the largest single project you have made that incorporated dovetails?
