Corner Chamfer Router Template

I have gotten some good use out of my router radius templates. I saw an interchangeable jig system that did a similar job and included chamfers in addition to the radii. First a reminder of how they work. You sit the template on top of the wood and use a special router bit that is a cutter with a matched diameter bearing on top. The bearing follows the template and removes any wood that protrudes beyond it. Ideally you cut off as much waste as you can on the bandsaw or elsewhere. Routers don’t remove a lot of material well.

I modeled a variety of them from 0.5″ to 1.25″. The length given is a leg of the isosceles triangle that will get removed, not the hypotenuse. See the diagram below.

I printed a stack of them in case the need arises, and uploaded the design to thingiverse. If they look odd compared to my normal prints, it is because I used some cheap translucent filament I had lying around. I figure they will get torn up eventually, so no need to use the good stuff.

Vise Rebuild

I recently inherited my great grandfather’s vise. It isn’t some magnificent old pre-WW2 piece of hardware that shows they really knew how to build them. It was purchased in the 70s and has an old green paint that looks like a faded version of what harbor freight uses today.

Still, no reason to get snoody about it. It is a really beefy looking vise compared to my little red one, it appears quite serviceable, is kind of an heirloom, and why toss something when you can fix it! It isn’t in horrible shape, but I wanted to do something before the rust moved in any further.

Everything came apart easily with the exception of the jaw pads. Their screws were in very poor shape and took some coaxing to get out. Looks like someone tried and failed earlier. I will replace these with something that accepts a hex key.

All the other minor screws and smaller hardware looked to be in good enough shape to keep. I put it all through a hot ultrasonic bath with a rust remover/inhibitor.

With the small parts taken care of I took an angle grinder powered wire brush to the main body parts of the vise. A flap wheel was used on the non-painted parts. They shined up a bit, but with all those deep gouges it will never look like new. Not sure if that means it is a soft casting or saw very heavy use. Everything remaining got a heavy coat of rust preventing primer.

I wanted to gussy up the dreary green, so I broke out the vibrant red paint. It kind of looks like my smaller vise now. Big red and little red. Everything that moves got oil and I bolted it down to the new heavy duty workbench. Everything else below the bench is mobile, but this is going to see some heavy use, so permanent fixing is justified. Its first job is coming just around the corner.

Heavy Work Bench

Shop work is still mostly getting usurped by home improvement projects. In moving stuff around the shop it occurred to me that there was some space for a work bench. I want something very sturdy to attach bench tools to (vise, bench grinder, anvil, etc), but also a place I could sit and do repairs. I worked out a design that requires most of a sheet of 3/4″ plywood and a hand full of 2x4s. I started by planing 2x4s square and gluing them together for extra thick legs.

The frame is 4ft wide which goes well with a 4×8 sheet of plywood, and 8ft 2x4s. The recessed bottom shelf gives some space for storing bench equipment when not in use. It would store more and be more accessible if it was full depth, but I wanted leg room so I could sit comfortably at the bench.

I screwed together two sheets to make the top. I was going to glue them, but screwing was good enough and I can replace the top piece if it becomes damaged. This is a very stout table.

Bare, and in its final resting place it looks pretty good. Time to load it up with junk! From left to right, my big red vise from my dad, old bench grinder turned buffer, anvil, arbor press, carved depression used to hammer bowl shapes in wood, and bench grinder on the bottom.

Most everything is attached to thick pieces of wood. This lets me put the tool wherever I need it and clamp them down. I made sure the table top protruded from the legs far enough so I could clamp anything across the entire width. I kept thinking of fancy dovetail sliders, or bolt patterns, or bench dogs that would let me install a wide variety of tools. In the end a thick top and some C-clamps is simple and effective.

While I was dismantling parts of the garage to make space for this bench I pulled off these shallow shelves. It was kind of perfect for what I wanted to add to the bench. These shelves can be used to store my electrical/electronics stuff. That jives with my idea of this serving as a part time repair bench. The shelves were up against the wall and didn’t have a back. I added one to keep stuff from falling out the back.

The lower shelf has a power strip and commonly used equipment. It probably needs more organization in the top shelf. For now I am going to live with it and see what gets used often, and what can live elsewhere.

A front cover helps keep the dust out and things from falling off the shelf when banging on the table. Two bent brackets catch the front door on the right hand side, and a swiveled part holds it at the top. To remove you just swivel the one catch and slide the door left a few inches. That way it can be removed or installed even when the table is covered in junk.

I have had it this way for a week or two now and already I christened the table top with grinding detritus and grime from the next project. We all knew that pristine surface wasn’t going to last long.

Chimney Cover

Home buying is a nerve racking experience. Thrills and surprises await you around every corner. One big one is the home inspection. On something as big as a house there are always items that crop up. You have to decide if they are deal breakers, or if you can take the risk of them being worse than the inspection indicated.

One thing that came up on ours was that the chase cover on the chimney was rusted. It was a surface rust, no emergency, but something to not ignore. A winter break gave me the time, and cooler weather, to get up there and do something about it while not dying of heat stroke. Close inspection revealed that it wasn’t bad and some cleanup plus paint would add many more years of life.

The big square chimney cover bridges the gap between the chimney pipe (might not be the right term) and the wooden structure sicking out of the house. My plan was to take it off, bring it to ground level and do all the paint work. The trick was I couldn’t figure out how to get that top little set of square covers off. I tried rotating the assembly but was worried something in the wall would come apart. 10 minutes of googling while on the roof didn’t give me a good answer.

Chimneys are completely new to me, so I am just feeling my way through all this. The section of roof is pretty tame so I took a grinder up there and did everything on the roof.

Sure enough, the rust wasn’t that deep. I knocked it, and as much other crud off as a I could with a wire wheel and came back with a coarse sander pad. There is still a lot of zinc left, but I had read a self etching primer would bond well with it. A few coats of that, and It was way too hot to keep working.

I came back the next day, sanded the primer and used a full can of high temperature white enamel. Even early in the morning the metal was getting hot and the paint dried too quickly. It isn’t a great paint job, but looks fine from down below. The original plan was to do this all on the ground in the shade. If I had known from the get go I was going to be working on the roof I might have opted to brush on something instead.

I replaced the rusted screw hardware with epoxy coated torx head screws. There is a thin band of metal that covers the gap between the pipe and the newly painted cover. The old one was pretty rusted, but a local fireplace store had new ones, so I replaced it. Not my finest repair overall, but it won’t be rusting through any time soon. When this needs work again I might be calling a fireplace expert of some sort.
