Need to replace our gate to the back yard

So this access gate on the side of our house was kind of janky when we moved in in 2008, but today, it's down right awful. I use the gate enough that it makes sense to replace this with something that will work nicely, won't drag across the pavement and feel like it's going to jump off it's awful hinges at any moment.

I had some notion of a field gate much like Roy Underhill demonstrated in one of his episodes with real mortise and tenon joinery. But first I need to make sure the hinge post is still serviceable. It is a 4x6 pressure treated stick of wood set in concrete at the base that still appears to have some years in it. I'll try salvaging this. If anything it would be nice to have some sort of attachment about 3' off the ground to the house. It would *really* help stiffen the post, and I think it's feasible since the house's cripple wall reaches up this high, so I could just drive in a few long skrews to attach a firing block between the post and the house siding. maybe?

I'd use this type of hook-strap hinge, fully threaded through.
See where I'd apply a spacer block to brace the hinge post. I was thinking of using some spare teardrop siding from the house to attach upside-down to the house proper so that the surfaces mate better. Do I apply caulk to prevent water intrusion?

douglas fir base for finial of a lost artist

my long time comrade in arms and bikes, sean of 10-digital had a neighbor who passed recently. i met the man once during an open house. he was an artist, and had completely transformed his west oakland loft into a studio. These lofts are arranged in a way such that the east facing walls are covered with glass. He had a very large curtain in silk (i believe) and a long stout rod to hold it up. Whoever acquired the place, removed this assembly, and abandoned it on the sidewalk, to my dear friend's horror.

sean recovered the fabric, and one of the large finials that had been threaded into the ends of the curtain rods, and asked me to somehow provide a base for this to display in his home. They were about 6" in dia x 12" tall. So here we are with a 9" dia base roughly 1,3/4" thick with a 3/4" round nose bit applied to the edge. haven't figured out the finish yet. maybe nothing, maybe wax, maybe a bit of oil. maybe paint?

some time spent mocking up the base in cardboard to get a sense of the proportions. The finial was a moulded piece and has some 1/4x? threaded shaft on its base that would skrew into a 3/16" hole just fine with some wax coercion. We originally thought to make the base ovoid, but i quickly realized the base needed to be someting that provided stability, no distraction. stay out of the way of the finial.
I used a few tricks to make the circular cut on my band saw with a plywood sled that I ran along the fence at the 4.5" radius, before clamping to the deck. there is a wooden dowel pin in the plywood sled that feeds about 3/8" into a hole bored into the base to hold it in place and spin freely. after moving the fence out of the way, i was able to cut a circular base from the fir. It is riddled with some sort of wood boaring insect's holes, so i will have to run this wood through the oven to be absolutely sure nothing infects sean's house!
I used the same plywood sled to rout the edge corner detail here. note the use of a fast clamp "cleat" at the aft end of the fence that i could butt the sled up to for support while i pivoted the assembly into the spinning bit. This way felt like i was in good control of the cutting, and was able to take a clean cut in 3 passes. After this, it was just finish sanding.
Just in case he wants to hang this off the wall, i fabbed up a small aluminum cleat that is inset from the base (so that it doesn't scratch the table). Just in case he wants to hang this on the wall somewhere. It works fine with a washerhead skrew

quick roubo bookstand

On pager-duty this weekend so i was chained to the garage but, hey, i needed a low pressure quick project to do after the tedious and exacting work with our bed.

some offcuts of sapele from my kitchen countertop were just the ticket for a Roubo bookstand. there's something elegant about carving the knuckle joints out of the middle of a board, then slicing it and seeing the work part like magic. i also wanted to practice a bit of relief carving. it is work i plan on doing more of when there's less furniture to make for our house.

Well today it wasnt magic with the knuckle joints. they needed some persuasion to open up. Should have made a few more action shots of my chisel action. i drilled out the slots where most advices suggests using a pad-saw. I've seen Schwarz use a single drill hole that he uses to "floss" the cuts with a fret saw blade. I drew a series of pilot holes, and then used his hole cutting technique to connect them. either approach is a b*tch. alack.

This one is about the size of a touch-screen notepad that we use for consuming the news at table.

queen size bed iii (fin)

continuation from part ii I Used P. Galbert's chair finishing schedule from his delightful book "Chairmaker's Notebook". It involves a layering technique of red milk paint and then black, with a burnishing to let the red eep through in spots. then a topcoat of thinned out oil poly. the paint i used was general finishes' which comes really too thick from the can so i water it down a lot to get it to that inky texture that Peter discusses. it's a lot of work and was a good practice.
Picking up from last log entry, I am now fitting the stretchers to the footboard and headboard sections (which were previously mortised before glue-up. This being poplar it was not too hard to get them driven home.
Here's a detail of my glueup plan for the foot board (which is how i did the headboard's lower stretcher, too). These will be pegged as well just to be damn sure
I wanted this pic included to illustrate how i drilled the holes into the stretchers, using a long 3/8 bit and the post's predrilled holes as a guide. I took the time to build some clamping blocks to attach to the rails so that they would hold the assembly together after It ahd been squared up. worth the time, and it worked a treat, actually. i was sweating this a bit.
I neglected taking a pic of the frame with the red undercoat...probably too caught up in the fact that i was painting something so big, so it is with a few coats of black-ink
and here i'm burnishing the black to just skim off a bit of the high spots. there are some wobbly places from the spoke shave that reveal my familial tremor. just have to roll with it. i like the tool marks, as long as they add to the overall effect. nice little scallops out of the wood that really show in this finishing technique.
Mr. Jonas Jensen's blog here discusses aging hardware using the acid from burning onions with your hardware to age it. I tried and like the results. Basically i just heated up my bolts really hot on the stove, and then caked them with some minced onion, 'quenching' them a bit. I returned them caked with onion to the flame and it really did burn those bolts nice and brown. I love carmelized onions.
Here it is installed. I built it maybe 2" too long and will have to adjust at some point. We are getting a fancy new mattress delivered on Thursday, so i will wait until it's here before making any final revisions to these rails!
Oh, PS, I built this "spine" for the mid-span support of the slats. Queen sized beds are 60" wide so it's too long a reach to do without some sort of post to keep things level. this was skrewed to the slats

queen size bed ii

Continuation from part i

well a fair bit of water passed under the bridge. here the headboard stands, in the white. THe frame is in poplar and i plan coat this with milk paint using a 2 tone schedule: first red, then a bit of topcoat, then black. burnishing/scrubbing will show small patches of red through the black and I think that will be nice. The center panel is reclaimed redwood from some northern CA water tower. I pulled 1/16" sheets of veneer off the bandsaw and applied this to a substrate that was scribed into the frame

first a small change to my shop arrangement here. i pushed the workbench up to the south facing sidelights of the garage and hung some tool hangers on a piece of scrap 1/2" ply on the wall. So far this has been really pleasant to the workflow.
I originally conceived this project to have a curved panels, captured into grooves routed into the surrounding frame. I tried a 3 layer layup using solid poplar sheets milled to 3/32" thick. Unibond 800 urea formaldehyde glue bent around a platen like so. However I was not happy with the springback and I was worried about how the hell to scribe this into the surrounding frame.

Maybe I cuold have used a thin sheet of bendy-plywood between the two layers of veneer, and it would have hugged the curve a bit better. I have searched and searched for ideas on the web on how to do this but still no go...

I started with laminating poplar up to make the headboard posts such that i could bandsaw the curves into the raw wood. I guess this is brute force way of doing things but poplar is cheap and the joinery is a bit easier to figure out if it can be done at 90 degrees. I made a few templates to make the lines. I freehand this on the bandsaw. It's helpful to keep the offcuts so that you can doublestick them to the piece when cutting the adjacent lines.

Here you see i've used the tablesaw with a crosscut sled to define the tennon shoulders for the upper rail joint.

Now i have the rough frame assembly. My next move was to bandsaw the inside curve and then scribe a panel to this
I pattern routed a bunch of ribs out of a full scale drawing and notched them into a leading and trailing edge which i fitted into the inside frame.
I estimated the rough size of the leading and trailing edges from placing a rib insitu. I'd then use a jack plane to shape the 8deg bevel on each edge of the assembly once it was all glued up.
i will be laminating the veneer to a 1/4" nominAL wigglewood substrate glued to the subframe. i figured it'd be easiest to just scribe in the two curved pieces on the side and then skrew in the middle panel
i used washerhead screws to clamp the wigglewood to the subframe while the glue dried. I then applied some putty to the screw holes after the screws were removed. since the veneer is so thick, i dont think i needed to do this but it was easy enough to do.
here's what the panel looks like from the underside. I filled out the curved sides with some spare ribs. Since this is facing the wall, i figure it's okay to reveal this stuff.
here are the veneers that I pulled off from the old redwood, edge jointed to be about 16" wide overall. bookmatched. The wood is so dry and there are a few deep cracks running throughout that impart some "rusty" streaks. I'm Ok with this though...The green tape is something called "binding" tape. it's wonderful masking tape that has a stretchy property, so it works really well at pulling edge banding to plywood, or in this application where you're edge joining thin sheets of wood.
I am using some Unibond 800 that is past it's shelf life but still seems to dry. it's too cold in the garage to cure properly, so i set up the vacuum bag to chooch all day and over the night. luckily it fired off by the morning. The pump is fairly quiet so we were able to sleep despite the noise
To make the bandsaw cuts, i kept the remaining offcuts and reattached them using doublestick tape so that I could make the adjacent cuts
Here's what the backside looks like. It's not so glamourous but since this is the side that faces the wall, i'm ok with it. the panel will be skrewed into place by the tabs you see here

slight detour into some spoon carving

i think i'm burnt out.

i'm trying to attack this bed frame project but keep looking for other things to do. so much compulsory work this year in my shop with the kitchen and bath the time i started making furnace vents for the floor kicks i had had it up to *here* (points to throat) i just want to have a bit more fun. try to use my hands and find their way through the grain. drape this mindset with a long standing desire to get into the kind of woodworking that i *really* want to do which involves carving and cleaving tools. I really want to build some wild appalachian ladderback chairs someday. work with green wood entirely.

well last couple days i just decided to let things run their course and finally set myself down to carving some spoons. never tried that before, and wow has it been fun! Today, i carved out a spoon from a knotty cut of madrone that our friend Suki handed me after we returned to her house from a walk in the hills above the Russian River.

I wish i had taken a before pic of the madrone. it's a "weed" up in these parts, but gorgeous and tight grained. extremely hard when dry, but carvable when it's green. It had a few knots that needed to be taken into consideration, but when you flow with the grain of the wood, you end up with some pretty cool shapes. the crook of this spoon just happened that way to meander around a knot.

I don't have what you'd call the best spoon carving toolkit, which might include a hook knife and a larger gouge. instead i used a 1/2" #9 sweep gouge for the bowl. I would like to get a hook knife kit and then maybe a wide #7 gouge as well to help hog out the bowls. carving is very much about setting yourself up to take clean cuts without putting any of yourself downwind of a blade's throw. I didn't take the interim shots of the spoon's progression. I hogged out the bowl from the wood billet first, then roughed out the shape on my bandsaw, then refined it progressively using a knife chisels and my spokeshave. I further refined the bowl using this sort of cut where my curled up fingers hold the gouge and only allow a small amount of movement. So many tricks to learn.

while at Suki's place, this 6board chest caught my eye. it was a very handsome box...
