OK, I've always said I could do just about anything a shade tree mechanic could do, I just didn't have the experience of making enough mistakes to know what to do the first time. Seems I should have checked the Internet before using hole plugs with the Kreg jig pocket holes. Most guys don't expect the plug to fit all the way in! I was spoiled with my first experience on the farmhouse table -- the plugs fit easily and all the way in.
With the "Chippendale-ish" bench, the plugs didn't fit real well and they were too long to go all the way in. So, for the ones that were tight, I sanded them on the belt sander. To get them all the way in, I cut off the blunt ends with the bandsaw. Neither process seemed very safe, but I made it through all 46 plugs plus a few more with only slight filing away of two fingernails!?!?
The Internet says to put plugs in microwave to heat up and drive out moisture that has caused swelling. They will fit better. Good idea; I'll have to try it on the next project. Also, don't expect them to go in all the way. Cut off flush and sand. Heck, just use 3/8" dowels and cut off. OK, that probably works, too. I don't have one of those fancy Japanese, flexible woodworking saws, but maybe I now have a good excuse to buy one.
Anyhow, progress has been made:

Oh no, more pockets to fill. Yes, I used the plugs again with sanding before checking Internet
Instructions called for using 6d finishing nails for seat slats, so I did. Had to adjust spacing with custom-size spacers cut to order -- 1/2" was too small, 3/4" was too big. It worked:
Oops, instructions showed installation of arms as about the last step, but didn't say why. Seemed the bench would be sturdier with arms installed before putting on slats. Only problem: tough to use nail set under arms!
Got it anyway. A little putty and nail heads almost vanish.
Another project was getting boat/trailer under lean-to without "spotter". I've done it with SUV a few times, but found myself getting out to check clearance off and on. Just happened to have extra trailer hitch ball, so installed it on the 8N. Much easier to see clearance on both sides of boat. Just a bit different process "fronting" the trailer as opposed to backing. Notice the slight "swerve" in front wheel tracks under the box scrape.
Shoot, this is so easy, I may be able to put that black car hauler in the background of first picture under the lean-to. But not until I remove all those classic 1967 Olds 442 parts. . ..
