Picture of Gas Powered Blender
So you'd like to have a nice blended margarita out in the middle of nowhere? So did I. All you need is gas trimmer and a blender to make blended drinks in remote areas. Of course, I'm still working on how to make ice without electricity.

Step 1: Parts is Parts

You'll need a gas powered weed wacker type trimmer. If you use an electric trimmer, you've pretty much missed the point of this project. You will also need a blender of course. Mine had a plastic base so it was really easy to cut up with a hacksaw.

Here's what I used to cook up my gas blender. Your mileage may vary.


1 ea. Gas engine
1 ea. blender
4 ea. 10-24 locknuts
4 ea. 10-24 x 3/4" bolts
8 ea. size 10 washers
6 in of 1" diameter EMT electrical conduit
1 ea. 4mm x 20mm metric screw
1 ea. 1 foot x 3/16" square bar stock


hack saw
screwdriver with various bits (torx, philips, flathead)
channel lock pliers
masking tape
aluminum tape
dremel with cutting disks
drill bits
friend with welder

Step 2: Preping the engine.

Take off all the unnecessary parts off the trimmer: the shaft and the head. The output shaft of my engine received a square shaft so I bought a foot of 3/16" square barstock from the local hardware store to use as a spindle. The base of my engine is also nice and flat so I didn't have to modify the bottom to keep it standing upright. I think I will add rubber feet to the bottom to protect the engine from scratches when operating.

Step 3: Preping the Blender

Take apart the blender. you'll need the pitcher, the receiver for the pitcher, and the toothed 'gear' that meshes up with the bottom of the pitcher.

Unscrew the base and open 'er up.

Unscrew the toothed 'gear'.

The motor on my blender was screwed to the top half of the base with four screws hidden under little plugs that I had to drill out.

cool. would you think a 43cc two stroke scooter engine is too powerful? I kinda do
phinch (author)  bombmaker25 years ago
I've seen a V8 blender on the web somewhere, you just have to make the carafe strong enough....

Jeremy Clarkson made one for Top Gear, and also a rocking chair using a V8 engine:

man is that a 4 stroke looks like one it shouldn't run in that position because it is a horizontal engine and it is running upside with the crank case oil not properly lubing the engine parts down also a 4 stroke will not have as much rps as a 2 stroke and a 2 stroke gas no problem running in any position as long as it has fuel to the carb so use a 2 stroke weed eater and put that 4 stroke on a bicycle
damn. make a smoothie in 1.5 seconds
I also have a string trimmer engine. I believe 23cc.

Would suggest to warm up the engine first, then start mixing.

How much did this end up costing? I think there is a commercial product called "The gator" or something similar that is in fact a gas powered blender -- just not as cool looking :P
phinch (author)  trebuchet038 years ago
The trimmer was given to me to fix. I saw a similar model on for ~$150. The blender was my old one. but a new one shouldn't cost you more than 40 bucks. The drive shaft was a couple of bucks and the screws were less than $2. If you wanted to start with all new stuff, you could build one for less than 200 bucks.
right on :P Recycle free stuff :P Hrmmm... I think I might have a trimmer engine sitting on a shelf at home... I will have to check -- probably will need some TLC though :/ And I have the same blender :P

If you do this project I'd like to see what you come up with.
I'm thinking attachments... for fun... gas powered salad spinner :P what other appliance requires a similar motion? spin art (sounds really messy) salad spinner ....
Cotton candy, food processor, mixer, coffee grinder

this is great, i've been wanting to try this for some time now but thought there was way more machine work to get the shaft to mate with the blender. thanks alot!
me and my friend made one out of an old lawn mower and titanium blade(tinu sheet of titanium). we could grind a brick
phinch (author)  Thelonelysandwitch6 years ago
got any pics? or vid would be even better!
I definitely don't have a vid, but I might have some pics. ill check. That was so cool when we pureed big rocks and water

There are two Ways to Cool without Electricity (Well, without an electrical plug at least.) The First would be to build a compressor refrigerant type system to run off a gas engine. Haven't done the calculations though, so it may be too costly gas-wise to make ice from liquid water in this way. The Other way would be to essentially make a generator from a gas engine and a car alternator and run off a bunch of peltiers off of that. (or an electric compressor refrigerant system)

There's a third way to refrigerate without electricity, but it might be hard to do homebrew style. Gas refrigerators (like used in RV's) use some sort of venturi effect and chemical reactions to somehow heat something, and then have the flow carry more heat away with it. It made some sense to me when I saw it demonstrated.

I was thinking about using dry ice to make water ice.
jongscx phinch7 years ago
if you're gonna lug around that much dry ice... why not just bring its mass equivalent in regular ice?

Looks like something out of the Red/Green show. I love it.
I have seen this type of blender on Northern Industrial tools web site. It looks more like a table with an engine under it. and a pitcher on top of it. search for gas blender or Item# 900100

If your engine generated power, you could use a freezer.

Very cool I have been thinking about doing this for some time now.I have all the parts and now need to get to work on the assembly thanks!

Get ready to build one of these myself. i post pics when i am done top show you what i engineered.. I do have a question.. Do you have an issue with the blender wanting to move or "walk" around when spinning. Just seems that with all the torque it may be an issue..
phinch (author)  Thermaljay7 years ago
I hold the whole thing down while blending.

Excellent...very Tim Allen-esque, a la "Home Improvement". Congratulations on adding more power to an appliance.

After a week of extensive testing in the Tahoe National Forest, I return with both my eyes and all my fingers intact. My liver on the the other hand is another story.

That is really cool. Great job. Here's a photo of a VW powered model my buddy Jonas Nash and I built. The next step is adding a working pitcher. The one we have does a splendid job of covering everyone with atomized watermelon, but I would be nice if the vodka didn't pour through.

walbro WB3A (i think that's the one) and a tuned pipe next? Sunnoco 'Blue' and straight castor, 25:1? Ring, ding, ding, ding, ding!

Great project (wasn't this an episode of "Home Improvement" ? Arh Arh Arh- More Power!
