North Bennett Street School Toolbox

Tool box door panel
I have been very busy attending North Bennett Street School full time, and Massbay Community College part time, so I have been inactive on the blog lately.  I finished my first furniture project at North Bennett Street School, and I am excited to write about it. After finishing the 20 drafting exercises, and the five full size furniture drawings that are required of first semester students at NBSS in the Furniture and Cabinet Making program, I began drawing the tool box.

I decided to use poplar for the case, web frame dividers, shiplapped back, and door frame, walnut for the drawer fronts and door panel, and I used soft maple for the drawer sides, backs, and bottoms.

After I cut all of the project components to rough width and length, I milled them to within 1/8" thicker than the final thickness.  I prepared the case sides, top, and bottom glue-ups with spring joints for strength, just like I did with the Chest of Drawers earlier this year.

I was able to use just one clamp for each panel.


After taking the case parts out of the clamps, I milled them to final width and length, and planed the inside faces of each of the panels.  Then it was time to dovetail the panels together with through dovetails.

The case is filled with four drawers for tools.  The case separated into compartments with web frame dividers.  I don't have any media for cutting the stopped dados, building the web frame dividers, or cutting the slot dovetail divider; however, the Chest of Drawers project uses the same joinery on a larger scale, and in solid wood that didn't get painted over later, so this post documents those processes, except it was all done by hand.

In my drawings, each of the four drawers were the same width.  My thought process was that it would be more efficient to make all of the drawers the same width, and the top and bottom drawers equal length, and the middle two drawers equal length as well.  In reality, each drawer turned out to be a different width and length from the other three, and each drawer had to be fitted individually.  I should have realized that would have been the result, and I could have used planning the tool box as an opportunity to experiment with proportional spacing of drawers. Oh well.

I built the tool box drawers with traditional dovetail joinery.  Half-blind, or lapped dovetail at the front, and through dovetails at the back corners.

I documented the time it took me to do each process, and it was about an hour and a half per drawer, so I managed to final mill the drawer parts, fit all four drawers, and dovetail together three of the four drawers in a day.

The fourth drawer's components are sitting inside the case.
I finished up the fourth drawer the next morning.  Gang cutting the tails drastically reduced the time it took me to cut the dovetails on the drawers.  Also I skipped the 140 trick on the tailboards, which further reduced the time it took, and I don't believe that it came at the cost of sacrificing how well the joinery came out in the end.

All four drawers fitted into the case, with the drawers bottoms in place.


I turned the drawers pulls on the lathe, rather than buying them.  This gave me the ability to customize their design.  They had to fit in the case between the drawer fronts and the interior of the door, without interfering with the positioning of the door.  It was good practice turning a set of eight matching drawers pulls.  They didn't come out perfectly identical, but I have that experience under my belt for next time I have to do it.  Unfortunately, I didn't tale photos or film any of that process.

After the drawers were finished, I made the frame and panel door.  That was a straightforward process, something I had done before, but this time I didn't have to do the majority of the milling of the stock and the joinery by hand.  That resulted in a very accurate door, which came out remarkably flat.

The finishing process for the tool box was a multi-step process.  I have wanted to use a pore filler compound on a project for a long time, and this was a great opportunity to give it a go. I taped off all of the surfaces on the drawers that I didn't want to get pore filler on, and applied a washcoat of varnish on the walnut drawer fronts. After it dried, I grabbed a can of water based pore filler, and a bottle of Transtint orange dye. I measured out an amount of the pore filler compound and mixed the dye into it in a spare container until I was happy with the color.  I used a plastic spreader to smear the compound into the large pores of the walnut.  I let it cure overnight, and sanded it back the next morning. The door panel was finished before the frame was glued together in order to finish the entire surface of the panel, and to avoid ruining the door frame, which got a painted finish.

Finished tool box
While the pore filler was drying, I brushed on a coat of black milk paint onto all of the poplar surfaces that showed.  Then I brushed shellac on the drawer bottoms.  While the finished dried, I returned to the bench room to continue work on the shaker nightstand project that my semester was working on as a group.  I hope to post about that project soon.  I was also working on an original design of a pair of country federal nightstands in addition to the shaker nightstand.  The toolbox case got a second coat of black paint, followed by two coats of thinned red paint.  The effect that I created with this was a burgundy shade of red, with a sort of antiqued or distressed appearance due to the black paint showing through the somewhat transparent coats of red paint on top of it.  I believe it complemented the dark walnut drawer fronts and door panel.  


After sanding back the pore filler on the drawer fronts and door panel, I continued adding coats of varnish to the walnut components until I was satisfied with the luster.  I then proceeded to brush shellac on the rest of the drawers' surfaces, followed by paste wax.  The case received a coat of shellac on the inside and two coats of varnish on the exterior, and it was waxed inside and out.  Once the door panel was finished, it was glued into the frame, which was then handplaned and fitted into the case, then painted.  After it was painted, I inlaid the escutcheon.  The escutcheon was a very exciting process.  I cut a diamond shape from a scrap of walnut and inlaid it into the door over the lock's location.  I framed the walnut diamond with holly stringing.  Before I permanently installed the lock, I drilled a hole for the key, and ragged on two coats of varnish on the door, then some paste wax.

I'll add a few extra photos I took after I filled up the drawers with my tools.




Here is a video of my process building the North Bennett Street Tool Box.  In all, I had a great time building this process, and I learned a lot about case construction.  I have so many resources available to me at the school, and the instructors are incredibly helpful.  I am looking forward to the next projects I build at school, and all the other lessons I will receive at the oldest trade school in America.
