Adam's plant bench is done

Home at last

Completing this project was an excercise in patience. Finishing wood before it's ready is always tempting, and always a mistake, so Adam and I challenged ourselves to be patient.

first coat of polyurethane dries
During smoothing, I used a 50 degree blade in my bevel-up smoothing plane because of the tricky grain direction around the miters, and learned why smaller cutting angles are preferable for softwood. The result was like a much smaller version of the pilling you sometimes see on a sweater.
a revealing moment of truth
We planed, scraped, repaired, made some mistakes, made more repairs, and ultimately sanded it to get the surface we wanted. We spread this over at least two evenings, which was barely enough.

tiles spaced while underlying mud dries
We started with one thin coat of glossy clear polyurethane thinned with a little mineral spirits. I like this finish because it's easy to get an even coat by wiping on and wiping off. Also, I like the way it soaks into the wood, leaving the wood's own natural sheen on display.

spreading grout, a messy process
This was enough protection that we decided to lay the tiles. Having never done tiling before, I was learning from Adam. We did a dry run first to check the spacing, then spread a layer of corrugated mud and set the tiles in their final positions. A bag of tiny spacers and finger pressure was all that was needed to get the spacing right. I was impressed with how easily this went, although the tops of the tiles were noticeably out of flat.
excess grout was no fun to clean off

Spreading grout was entirely different. We spread it over the tiles, packed it in the gaps, and scraped it off. At this point, the tiles weren't exactly clean, but the bulk of the excess was gone. After a few days, it was dry enough to wipe the excess off with a damp cloth. The difficult part of this was finding out that the grout (powder & water) was still fairly easy to dissolve in water, and tended to seep under masking tape, leaving dark stains on the wooden frame. These were sneaky but easily removed with yet another damp cloth. Also, the grout didn't come off very easily. I made some scrapers out of small padouk scraps, which worked well, but there was still a lot of elbow grease involved. I left Adam to do the bulk of this part and cleaned the shop instead. I wonder if the grout cleanup would have been easier if we waited longer.

Clean tiles. Finally.
Back to finishing. We masked off the tiles and went over the parts lightly with steel wool before applying a second coat of finish. After it dried, we both agreed that any more would start to build up a visible glossy layer, so we left it at two coats.

Last-minute adjustments.
Finally, we could assemble and admire the product of our labors, or so we thought. As it turned out, we had forgotten to take wood movement into account for the legs. Fortunately it was one of the hottest and most humid days of the year, so we learned this lesson by finding that the parts wouldn't fit, not by having the bench explode later. We adjusted the mating parts of the legs and top, leaving a little extra room this time, having learned our lesson. One coat of finish on the freshly cut surfaces and we were finally done.

The frame fits together and is ready to accept the top
Now that it's over, I've learned a few things:

- Woodworking is more fun with friends, but more challenging too.
- How to lay tiles. Grout is not my friend, but I'm glad for the experience.
- Adam's idea to make the whole thing disassemble without fasteners is really cool. I may use it again.
- Lots of miscellaneous hand tool skills. This project was crucial early learning for me. I'm very glad Adam was OK with his project playing this role.

It works!
Despite numerous errors, I feel pretty happy with the end result, and looking forward to using the reclaimed shop space for whatever is next. Maybe a tool chest.

Glue joint test

A single shaving that comes from both halves of a glue joint always makes me feel good about the joint itself.

This picture comes from yet another night of smoothing surfaces of the plant bench.

Finishing surfaces and breaking planes.

Adam and I dug into smoothing and finishing the plant bench tonight.

Progress was slower than hoped (as always), but we had good results and relatively few mistakes. I planed one leg assembly smooth while Adam took the excess off the miter keys in the top frame with a block plane.

One leg, planed smooth and with polyurethane drying
I only got a smoothing plane recently. Up until then I was relying on a jack or a joiner plane to leave a reasonable finish. I'm still getting used to the idea of planing without flatness as the goal. It went OK. once it was 95% there I switched to a card scraper for the last bits. Still had minor problems with track marks, but I think patience and fine adjustment more or less took care of it.
Miter keys without the excess

Adam did a nice job with the miter keys. Clamping the frame was awkward, but we made it work. Since the front surfaces of my workbench are not flush, it involved some blocks. Speaking of blocks, clamping a block alongside helped prevent the corners from chipping out, but not as much as planing with the grain (duh).

Half a tine short of a fork
And then I broke my jack plane. I had recently got the courage up to grind a camber into the blade and was trying to show Adam some thick shavings on a piece of scrap. We were talking about planing off extra material to make the mitres more crisp. I was trying to point out that we could take a lot of material off quickly if needed. I took off a few shavings from different directions, dialling in the blade depth as I went, and then the adjuster-fork snapped. So I guess I'll be adjusting it as if it were a wooden plane until I try to return it. Now I'm thinking about purchasing a replacement of higher quality. EDIT: since I made this post, WoodCraft did an excellent job of replacing the part with one from the next version of this plane. It is steel unlike the one that broke, and it has worked well for me for quite some time now.

Holding the broken piece. The plane behind it is the one that broke.
An aside about my experience with a WoodRiver plane: I bought my #5 without doing a lot of research, after trying one in the store. It performed well for me for about 2 years for a variety of tasks while I learned just how the heck to use it. Since then I've read a bunch of negative stuff about WoodRiver on the internet, some of it regarding business ethics, and some about quality. Until it broke yesterday, I was still pretty pleased with it, but 2 years is far too short a lifetime for any quality tool in my opinion. The timing is unfortunate since I had just cambered the blade and felt like It was finally pulling its weight. This just happened, so I have no comment on customer service or return policy, etc. I'll most likely stay away from this brand in the future.

Adam levelling legs. Just look at that focus!
One more item, out of sequence. Last time we worked on the bench, we tried the technique the Chris Schwarz recommends for levelling tables and the like. It worked brilliantly. In 10 minutes or so we levelled the workbench and the plant bench on top, marked the lines, and clamped it into sawing position. Sawing to the line is a tricky skill, and Adam and I are both green enough behind the ears that we were noticeably off in some spots, maybe a pencil line thickness error here and there. I set it on my wooden kitchen floor and it felt solid as a rock anyway. I think this method is a real winner.

Plant bench is coming together

I've been helping my friend Adam build a low table for potted plants. It's cypress, walnut, and tile, and can be disassembled into 4 parts without fasteners. Here are some recent pictures of it coming together.
