View Full Version : Apothecary chest - shaping the drawer fronts (1)

Having completed the dovetailing of the drawer sides into the drawer fronts, the next step is to shape the outside bow to match the chest.


This is the drawer to be demonstrated ...

The drawer blade has been removed, and receives a final tweaking to match a template. Every drawer blade receives the same treatment, and there is a template for each vertical row ...

The drawer blade is returned to the chest, the drawer is fitted, and the profile of the drawer front is traced ...

Below, the markings may be seen on the drawer front ...

The drawer is pulled apart. The grooves for the drawer bottom have been completed. The drawer sides received a 3mm deep groove, while the groove for the drawer front is about 8-9mm deep. The extra depth here is to allow for the inner curve to be later shaped, and that this will remove approximately 3-4mm at the centre.

Now the end of the drawer front is marked ...

Blue tape is added, and the excess removed ...

The tape is added to the upper and lower faces, and the template (from the drawer blade) is now used to mark the curve ...

Once removed, the cut lines stand out clearly ...

The rasping may begin. A start is made with a Shinto, which has roughly 10 grain on the coarse side (this is a Japanese rasp made from hacksaw blades. The other side is about 14 grain).

In turn, after the 10 grain comes the fine side of the Shinto, and then a 13 grain Auriou followed by a second cut file.


The surface is refined with a scraper ...

... and 120/22/320 Abranet mesh. You will ask why sand after scraping? The reason is that the sanding removes any scratches left by the rasps and scraper, creating a uniform surface. The final result is fairly polished. It is possible that I may go over this with a cabinet scraper prior to finish ...

This completes the drawer at this stage. The rear of the drawer front will next receive a complimentary curve. I hope to get to this during the week ...

The run out from cutting away the ends of the boards is noticeable (to me at any rate) ...

Question: Did you consider using a plane rather than the rasp? At any rate, the end result looks very good from here.

Hi David

The drawer fronts are too small for a plane, as is a spokeshave (they measure 100x100mm). The amount of waste to remove is also too little for a bandsaw, plus the height versus length makes it too awkward to do. The rasp was all that was left to use.

Looks good Derek. The runout would be noticeable to an experienced eye. However that person would know why. Does it hurt the piece, not in my opinion. For what my opinion is worth. I'd love to have it.

Like end grain, run out can be a feature in the overall beauty of a piece.

Once again Derek you have given the rest of us a work of inspiration.

Very nice Derek. Also pleased to see you are single handed in keeping Minnesota Mining and Manufacturing in business with your blue tape consumption!

I love the grain flow on your drawer fronts. Very very nice!

Thanks Jim. I am very far from finished with this piece. Drawers to complete, then there is a base to build. The drawer handles arrived yesterday ...

It just keeps getting better and better looking. This has been a real fun project to watch in so many ways.

I agree it's been fun to watch. Doing it? Not my cuppa! I'll stick with simpler designs. I'd be tempted if I didn't follow the process.

Beautiful work.

Impressive thing allready! The grain runout is noticable indeed, I don't know yet if I like it or not, mixed feelings still.

It's about 70x50 I guess? That's smaller then I thought it would be. I don't know how I got the impression it was much larger.

It's very beautiful work, I think you did a fantastic job.

I would be tempted to apply quarter sawn veneers (shop cut) to the fronts. The runout actually makes it quite difficult to see that the drawer fronts are matched from single boards and makes it very busy, which along with the dividers makes for a busy cabinet.

It's not that big, so a bit of busyness wouldn't be too dramatic in a larger room. If it were a wall filling cabinet, it would quickly become an eyesore.

Brian,

I agree. The regrettable part is he could have used pine and sawed the fronts to match the curve, ditched the difficult angled dovetails and be done by now. :)

Pete, that is partially true - it could have been done that way. However, then there would have been the need to deal with covering the pine. Two issue there: firstly, it places a very high demand on achieving a flat surface for the veneer (where a little out-of-flat is missed with mine); secondly, how do you cover the sides and leave the dovetails showing? I could add a third in that I do not have a set up for vacuum bagging veneer. (In the past I have only used thick veneer I bandsawed).

I was not expecting quite as much run out as there is as my method went to minimising the possibility as much as possible. It is interesting how much occurred with so little waste removed at each end of the draw. Imagine what would have happened if I had used very thick stock instead.

Derek,

I wouldn't cover the sides, I'd just be happy with an 1/8 thick piece of veneer and then the dovetails.

The kind of furniture we are talking about was pretty common in Newport, RI. They used secondary woods and veneers for many of the crazy curves they put on furniture made near there. I'd think a nice thick coat of hide glue and a batten made to match the curve would be just what the doctor ordered.

Since you already spent the time on the drawers getting them together, I'd get the veener you like, and apply it with hide glue and use a batten that matches the curve of the front and clamp the sandwich up. You could use wax paper between the front and the matching curved piece. I think your problem would be solved then all around. In fact, you could get some book matched burl and veneer the entire front so it all matches. Or maybe use contrasting ebony for the dividers and walnut burl for the fronts. Worth thinking about.

Pete
