Shaping edges with rasps and floats

I have not discussed how to get the beveled sides of a large panel in the absence of a sliding table on the table saw. Paul in California caught this, and asked me how I did it. I can summarize it as follows: I cut close to the layout lines on the band saw, and sneaked up on the final dimensions using hand tools — rasps and a float — prior to cutting the dovetail joinery.

You don’t have a large band saw? No problem! Use a jig saw.

No jig saw? Use a hand saw.

Just do it.

The hand tools accomplished what no other tool in the shop could do for me. The rasps and the float allowed me to sneak up on the final panel dimensions prior to cutting the dovetail joinery. In this first photo I am using a rasp to get one of the angled and straight edges not only perfectly flat, but also exactly to the layout lines (that is not rust on the rasp, but fine black walnut dust):

I used the rounded part of the rasp to shape the curves on the sides of the cradle:

Although the rasps leave a smooth surface, it is not good enough. I used a float to leave a finished surface on the edges:

This is what the float looks like – it cuts very thin shavings, and behaves very much like a hand plane set for an extra light cut:

The float takes very thin shavings.

In this final photo I show one of the straight panel edges just about ready for the joinery — the surface is smooth in all but a few areas, and a few more passes with the float are all that is needed to call this part of the job done:

The edge is almost ready.

It helps to have some hand tools to do a job when do don’t have a suitable power tool in the shop. Over the years I have gathered a basic set of these, to help me out in a pinch. And the price was right, as I have found them in garage sales and auctions. I know you can find them, too; then you will be prepared to do a job you did not suspect you could!

Extra hands during large glue-ups

Often overlooked, screw clamps are great when a second pair of hands is not available in the shop. For example, as I apply glue to the edges of what will become a wide table top, I use the clamps to stabilize the boards:

Using a mallet with good technique, and without damaging a board like I did on the first try, the edge glue-up resulted in a very flat board:

Old technology can be discarded easily. My old Craftsman screw clamps came to the rescue once again – I will keep them.

Bring in the lumber and let it acclimate

As I mentioned in yesterday’s post, we hosted the Guild meeting in our shop last night. Today was clean-up day, to move the metal chairs back into the storage area in the shop, and to gather up leftover water bottles, empty soda cans, and clean up cookie crumbles (yes, we do have munchies at our gatherings).

After cleaning up I headed to the Simpson & Sons saw mill, just outside town. I needed a few cherry boards for an upcoming project. As usual, Dustin, Lori, and the rest of the crew, were extremely helpful, climbing the stacks to hand-pick boards and hand them down to me. Back in the shop, I took a few minutes to handle a couple of phone calls; I cannot remember when I last sat in the open area in front of the table saw, but it felt great – it is a most unusual happening, but one I might practice more often:

Just back from the saw mill.

Not only has all the snow melted, but we have had two rainy days – actually, drizzly days and flooding of the Platte River. I make it a practice to bring lumber into the shop, to let it acclimate for a few days. To help it along, I lay out the boards and cut them to rough length; then they sit in the shop for a few days. I make sure to inspect every board carefully, marking areas I will avoid due to cracks and other defects:

In the morning I will do some preliminary machining of the cut pieces, just enough to get them flat, but nowhere near final thickness. This will allow me to check for stability much better, as I will be able to detect even the slightest cupping or twist.

On a non-woodworking note, our 5-year old granddaughter, Emily, has started using “her Mommy’s Facebook”, and sending Sandy and I messages. Last night she did it on the Facebook chat. Today I found a message from her on my Wall; and I noticed she had also written on Sandy’s wall. When I asked her tonight how she wrote on our Walls, she said “…I found ‘Al’ on Mommy’s Facebook, and wrote you a note. Then, looking in your Friends list, I found Sandy and wrote her a note, too…”

I was unable to contain my laugh. It was a pretty special day, thanks to Emily. She will be six in April.
