Is that nut partially threaded on then welded? Great Idea, Tone!

I use these a lot. They are somewhat aggressive but not as much as you might think.
The chain circlet is sandwiched by the metal discs. A pain to get the discs the right size but easy to change the chain after.
One for the tablesaw. Doesn’t slow it down much but makes lots of sawdust. Good for cutting wood that wants to pinch or dirty wood. Just file it and good to go.
And for the trimmer. A bit slow in saplings ( got to keep the revs up ) but great for brush.

So these are just pieces of chain sandwiched between something like two worn out diamond edged cutting disks? I’m going to have to try that out.

Yeah. Actually just old skilsaw blades with the teeth ground off. I put two blades on the table saw and turned it on then just hit them with a grinder. Lots of sparks and noise and trial and error but once they are made then they are good to go. The circlet of chain is cheap to replace. Pretty handy for shaping wood.

The grinder, what do you do for safety? If the chain pops off you loose a finger, maybe two. Put the cap back on?

When I have the chainsaw cutter on I definitely have the grinder guard on. Use safety glasses too as it throws a lot of high speed sawdust. If you push it suddenly it will kick and stall but is very controllable if you ease in and feather it.
The chain never pops off. It is held securely between the two discs.

Hi All,
I was cleaning up and sorting and found these two new 1/4" (pipe threaded) air line quick attach fittings.
Hmm!!
Thick walled.
7.5mm I.D.
4 mm drill outlet end. Internal step counter bored.
I see these as screw-in replaceable wood gasifier hearth air nozzles.
Available in larger “3/8’s” and “1/2” pipe treaded version.
Metric equivalents?

It would be M22 and M16? But 1/2 and 3/8 is used as normal overhere. In pipes, not bolts and nuts.

I posted this in one of my threads but figured I should archive it here.

I have done that before Marcus and collapsed my plastic filter barrel. Lol. I never tried it again. If I switch back over to a stronger steel hayfilter barrel I will try it again. Good Job on finding a new going down the road driving trick in cleaning the fines out of the charcoal bed. In gasification there is still new things to learn. BBB on down the road.

I could hear my barrels talking some if I was at high rpm, but my regular high idle seems to do it pretty well. Now it does weaken the char bed some since it burns so much so fast, but I just drive really easy when I need to do that and it seems to work really well at getting the vacuum ration back where it needs to be
