Decided I want a better maple syrup evaporator this year (had been using a modified charcoal grill/smoker) and figured the way to go is a wood pellet fired rocket stove as the heat source. Got that part built today, and it looks like it burns ~8 pounds of pellets an hour while putting out ~70,000 BTU per hour. Interesting type of stove, as it gasifies the wood prior to burning, which means a very clean, efficient burn. Which is also why there are flames shooting out the top even though the actual burn is right below the feed hopper.

Thanks! Will post more tomorrow as I get the rest of it built.

Btw, the stoves in these two videos are what I based the design on:

all those surup evaporators ive seen were these flat things which channels and you stood around em with rakes moving the stuff along a winding path with a fire under it...

you mean you can just do it in a pot?!?!?

Yup, rSin. The wacky channel things on commercial evaporators are only there to maximize production by way of making it a continuous process rather than batch process (raw sap in one end/finished syrup out the other rather than boiling down one huge pot). Traditionally it was done in 3 cast iron cauldrons over open fires, so there'a absolutely no reason you can't do small amounts in a big pot in the kitchen. If you search back through this thread you'll find the DIY evaporator I used last year, which was simply 6" deep commercial steam trays sitting on my grill (with a bit of sheet metal and a chimney added...). Biggest difference is that batch process needs a longer boil, which means a darker, more flavorful syrup. Which is not necessarily a bad thing.

This year's version will be much the same, but purpose-built for improved efficiency since the modified grill thing was a bit of a PITA and I'm no longer swimming in seasoned firewood.

Oh, somehow missed putting a beer bottle in those pics for scale... The steel tube is 5" square, and the riser/chimney is 29" top to bottom.

big as a sheet of plywood it seemed
was a neighborhood gathering event type of thing for them

I got my wood in for my kitchen knife set. More like half of it, but at least I can start finishing some. They came in a 1 1/4" x 1 1/8" x 5" blocks and I cut them to 3/8" thick scales. This gives you enough wood to shape with the belt sander for the handles.

Ready for drill press


Epoxied and next step is a couple of hours of shaping the handle and then polish it. Hope to do that Wednesday.

i finally backed my yotajeep out of the garage under her own power.

1950 Willys CJ3a, now running on Toyota FJ60 axles, brakes and steering. the conversion was 100% fabbed and TIG welded here in the garage. also upgraded to 35" tires.

I still need to get the yota master cylinder in there so we have brakes. then the fab is done, and i just need to pull it all apart again for paint.

Second coat of oil on the nightstand and bed. I'll let it dry at least 72 hours, then a couple coats of lacquer, and ready for delivery. To Sacramento. 1000 miles away. Oy.

Hey this just in, your photo calls the buckeye 'stabilized'. What does that mean? Those knives will be beautiful.

"Stabilized" means that the wood was injected with a resin under high pressure.

Dfinnecy,
Yes stabilized is an injection of resin at high pressure. The pressure pushes out the air and the resin fills in the voids making it a harder and more durable wood. It also helps fight expansion and retraction, thus preventing cracks in the wood. Most soft woods require a stabilization.

I finished one knife yesterday afternoon














Here's what's left, still a lot of work.

Looking good! I wonder if you plan to fill the top edge where all the decorative filing is with something? Clear epoxy I'd guess? Seems like it would collect dirt/crumbs etc otherwise.

Cool project.
