Making The Till
Here I am using a whole article to explain just how I fit and set the till for the chest. A till is at least the verbiage I use for the small segregated area on one side of the chests interior. Its a nice place to store more delicate or smaller items.
I have put in several tills in past chests and I have used several techniques to pull it off, hidden dowels or biscuits mostly. Those techniques worked well but they left the possibility of a gap if I didnt have surfaces perfectly square and the glue up was very difficult to pull off without five hands. No matter how hard I try I still only have two hands, but even if I had five I bet Id wish I had six. . .
This time I was using thinner panels than before as well. The chest dimensions are 10 1/2 inches deep on the inside, so these panels were cut at 11 inches long by 5 inches wide by slightly under 3/8th inch thick. Instead of using any of my previous techniques I decided to go with the one described with the till in the school box in "The Joiner and Cabinet Maker" where the Thomas character cut some dados for the panels to ride in.
I had the choices of using a 1/4" straight bit in the router to plow out these grooves, but honestly, in those situations I feel like I have less control than Id like. So I stayed with the hand tools on this one, besides any excuse to use my router plane. I carefully measured, and remeasured, and remeasured again to set out where I wanted the dados cut using a carpenters square to set the angle at a good 90 degrees and making sure there was space for the lid to lay down flat with the larger chest lid closed. I then shortened the dado on what would be the upright panel by another 3/8ths inch so I could cut a haunch in the panel to help hide the dado. With a 1/4" drill bit I bored the ends of the cut to a 1/4" deep.
Then I used a 1 inch chisel to start all the lines to help keep the cut crisp on the surface. A couple strikes with the mallet, just to score down a 16th of an inch or so was a good start
Then I went at the material to be removed by alternating back and forth between a 1/4" chisel and a router plane with a 1/4" straight blade.
It is difficult to see in this picture but it shows on the panel how I went over the side with a small thumb plane to narrow down the edge of the panel to fit tightly into the groove. You can also see the haunch or step I cut in the top of the panel which helps to hide the top of the dado groove from showing on the finished piece.
Everything set I gave the two stationary panels of the till a dry fit. I was pretty happy how this was working out.
Then there was making the hinged lid. In the past my favorite weapon of choice here was a section of 1/4" brass rod. Well I used up the last of that a while ago, and I neither wanted to go out and buy some for this, nor did I think it would work very effective. The brass rod always seemed a waste to me because you could not see it. As I cut the dados I thought about alternatives. It seemed to me that if I were to cut the head off a 4 penny finishing nail (1 1/4" cut down to 1") that would be very effective.
I marked out the space for the nail pin in the lid with a scratch awl and followed that up with the appropriate size gimlet to hollow out the space. I did not want a tight fit for the pin, I over drilled the size and then glued in the pin to the lid with some CA glue.
Then I eyeballed and drilled out the space for the pin in the sides of the chest, No CA glue this time, I want this side to spin free. Infact I added a little wax to the pin before I went for the whole glue up.
With the till cut and fit and everything working well I went for another stage of glue up. Yes if you look at the piece in the picture below you would be correct in noticing the sides are not involved in the glue up. They come along on the next stage
You can see from the pic that by the time I got this far it was getting dark outside so I called it a night to let the glue up dry and come out the next day to tackle the rest of the assembly of the main chest body and the creation of the lid.
