OUT IN THE WORKSHOP (turning a ht into a saxaphone)

Burn.

I am required to wear pure cotton surgical scrubs and nothing else in the hyperbaric tube, plus my body is physically grounded to the frame of the tube to avoid any chance of a static spark. The tube is pressurized with pure oxygen to 2.5 atmospheres, and I stay in there for 2 hours daily. Anything hand held that might generate a static spark is to be avoided in such conditions.

I have a large, open wound on my right heel that has been making little to no progress toward healing, and the hyperbaric therapy is intended to promote that healing by elevating blood and tissue oxygen levels. It does seem to be helping, but not quickly.

Diabetes sucks.

Hi,
Just chiming in to see if you had made any further progress on your reeded barrel as I'm currently doing a similar mod to my barrel. I'm using the reed block and Walbro carby off a DLE 50cc model aero engine, should be interesting.

Cheers BJ

Did you add reeds? if so, can i do this to my old crappy 19cc engine with a grinder, drill, sawzall, etc.?

 

[schulze 123]

Did I use the reeds as well as the block? Yes. Can you do this mod to your 19cc motor? send me some pictures of it and I will let you know involved or what special tools (if any) are required.

Cheers BJ

ok, ok, refresh...

i been AWOL setting up my mill to CNC...learning to use it cheating by seeing another forum
theres this funky thing called "go to zero". if you forget to lift the drill out of the hole before hitting the button....one needs a new drill still keep forgetting...

anyways...

lastnight i got in the mood to mess with alloy again... i stopped at 230 am finally. so, the progress up to now sorta looks good so far. this is the block to take the carby, with recess for reed valves... gotta flip over still.

soz, cam phone.... still doesnt stop the urge to try and blow that swarf off!

just a lil bit more....now i need a new piston and um...some sorta manifold for that carb still.... back to the scrap heap

you can tell its been a while cus its been decided the cylinder will make a good nursery by some maternal mudwasp...

my only concern is flow through this thing... i may be doing version2.1 with twin reeds at an angle like they do on real 2strokes... meh. i was using the alu i had handy...

Hi Troops,
Just a few pictures of the progress I have made. I think just a few minutes work with a nail file should see it finished (I wish).

Cheers BJ

Schulze 123,
Where will you be tapping the pulse tube on that Walbro carb?
Also what size is that carb, I've always wanted to put a Walbro or Zama on mine.

i believe thats the yellow line there....seems to run from the black manifold at least.... its an external pulse feed carbie. out of twenty or more ive only got one of these...

this raises an interesting point...

schulze, remember the pulse needs to be from the crankcase side of the reeds... not the carb side. it needs POSITIVE pressure.... youre possibly better off blocking the hole in the manifold and tapping a hole into the crankcase itself? or into the manifold youre making there...
