Yes the CUT 40 is a Chinese Plasma cutter and they work quite well on thin plate if your air supply is really dry. Water really blow out tips even on the best of cutters.

Those guys on cars & cameras are a hoot to watch. They could break a 250 pound anvil with a 2 pound hammer!

Any tolerance is "good enough"!

LOLs, on CarsAndCameras! I looked CUT 40 up on YouTube reviews and it was informative on what it will do.
There are some good prices on welding equipment on Amazon one listing gives more at the bottom of the page:

Something to think about for the shop and winter projects. We had two big trees to remove here by a
professional tree service. The guys had some expensive equipment to do it with. They had a chipper
that could grind up a 3 ft. tree trunk which was fed into the chipper that was pulled by a truck that
had a enclosed box. We've had thunderstorms pop up recently and I suppose it's going to be a damp
Fall just in time for harvest. Got a 32-tooth sprocket coming in sometime but wouldn't have time to
mount it with all of the outside work distractions going on. I need to put suspension forks and disk brakes
on that bike so it will be a few months before I can afford it since Winter weather is going to be coming
in and other things need to be taken care of first.

Dennis My next door neighbor just retuned from northern harvests in upper Midwest and will return latter to finish the harvest off. Custom combine work from Texas to Canada has been a way of life in this area since the days of "thrasher crews" of the very early 1900's, and my family was no exception, though I'm the last to actually have participated in real agriculture as a way of life and not just an investment.

Combine technology was where I first dealt with complex devices running chains & that was preteen experience working in the fields and shops alongside men...socially unacceptable today of course, which might explain some of the confusion and conflict which our children and young adults express unendingly. Learning to work in ones twenties isn't working out for most and wasn't an option in my generation. Every member of every family had real work to do... regardless of age. We had to work each day in order to survive!

I use to go help the neighbor kids, go do haying and such. In the field all day, probably not, but dining table seemed like 20' long, tons of food. It was work form sun up till sun down, small old tractors. Even at home, had to do it manually. Don't know how many a lawn i mowed with old reo-type push mower. Hand drill, hack saw, files, were the way to building........Curt

I hear you on that! I was raised on a farm about a mile from this place and even my younger brother who is 6 years younger
didn't do what I had to do on the farm. There are exceptions but farming now is a lot easier with all of the nice cabs and air
conditioning on the tractors. I worked pulling corn and weeds out of the bean fields when I was 8 and into the later years.
My Dad had a corn sheller truck where we went to farmers in the area to shell corn and even at 14 years I drove a tandem
axle truck with the shelled corn to the elevator to get unloaded. I had to sit on a pillow to get up so I could see to drive and
of course it was a manual transmission on the ole International truck with air brakes. My Dad had another older truck which
was an ole middle 50s Ford single axle gas truck which I also drove. We had am old Massey Harris combine which of course,
didn't have a cab so the dust would fly combining the beans. The corn was not combined, a 4-row picker a International 400
tractor was used with a wagon pulled behind the picker. The heater was a "HeatHouser" used to keep you warm which really
worked good since there was a windshield attached to it. Months before I graduated from HS I enlisted into the Air Force since
most of the fellas had to register for the draft and the Vietnam War was going on and that was in '65. The wusses either got
married with kids and deferred or went to college. I new that the Army and Marine Corp. wouldn't be good a good education
when you got out if you were lucky to survive the Vietnam War. Some of my friends got deferred (wussed out) and really never
grew up and since we were the from the "BabyBoomer" generation what you see today is a the generation of "Millennials."
This Country should have done like the Israelis have done, required military service for 2 years so the kids can grow up with
responsibility and appreciation for the Country. Some of the younger generation are good workers and have been raised right
but I can't say that for all of them and my generation. That Massey Harris combine my Dad had, he bought it to combine the
wheat in Kansas/Nebraska when the War was going on. He drove that combine all the way back here to the farm to use when
the harvesting was done. They had a convoy of workers that went out West to help with the harvesting. He put some brandnew
lights on the combine to run with the other fellas at night combining and when he got back here with the combine he parked it
in the field for harvesting and some lowlife idiots stole the lights of of the combine. He was really mad about that I remember!
My Landlord always brought up that trek out West for the harvest and who went with him, my Dad and his friends to help in the
harvest. I barely remember that since I was a little one back then.

Not as much progress on the drivetrain as I expected but what I got done I am satisfied with.
My #41 chain got cut with the axel in the full forward position and it took a roller chain draw tool to get the master link in. My logic "chain will stretch and give me slack. Not!" so I started with a half link and have a lot of take up. So to day half link is gone and I built the chain up to take the Master link again restrung the chain an my guestimation sees the drop out slots not coming up short.
The bulk of what I have posted here I suspect should be included in my Sportsman Flyer build thread and there is only one for a 79cc build.
But Pat thought for sure that the reduction drive assembly correct but other miss alignment kept cropping up.
Once I get some seat time we can evaluate.
Sunday is my last day with no schedule. Monday is back too the Tool Room and my machine shop time will be just the same. Me and the Missus have one last full day together.

Back in the shop Sunday and got the #41 drive chain settled by adding a link and it takes up most of the drop out using the tugs. Pedal side has always had slack chain because Pat uses #41 on both sides and I wanted pedal side to be distinctive and did by using BMX all 1/2 link gold chain. Last year before my bad chain line issues side lined the Flyer. I used an idler mounted off the rear axel.
For what that idler did for the pedal chain, no complaints.
Second time around I see an excellent rearrangement of the idler by mounting it to the under structure of the center stand. Manual mock up is very encouraging.

I finally got the 32-tooth sprocket in and went to the trouble of putting it on early this morning. The sprocket was a steel
sprocket and looked good but I had a feeling I need one with less teeth on it. I managed to get the bike out early to see
if there was much difference in going from 36 to 32 and there was a gig difference. The smaller sprocket just made the
bike get up to a crazy speed sooner. The sprocket wasn't bad for cruising and I need to go to a lot smaller in one.
MBRebel is the only vendor that has sprockets that I have found that go smaller than a 32-tooth sprocket. Lynn has a
24 and 20-tooth aluminum sprockets and I am seriously thinking about the 20-tooth. That sprocket should make it good
for a road speed of 25 mph with less mirror vibration. The 36 sprocket was not really good since I don't need to be
winding up the engine just to run 25 mph on the open road. I did notice that running the same test distance with the 36
versus the 32 that the fuel mileage was better even though there was more wind this AM and I checked the throttle
response with more than usual higher rpm. I refill the fuel tank before I use the bike every time so it does show a
difference. Running higher rpm just to cruise on a open road is a waste of fuel mileage, wear on the engine and the
drivetrain. I'll let you fellas know what I find out later when I change over to a higher geared sprocket. Looks like I'm
going to be real busy with outside work since the grass is growing again and we are getting equipment ready for harvest.

That is how this hobby so called inexpensive mode of transportation is. The work I got done coming home from work will get me back on the road after a one year hiatus.

Well Tom, I'm going to try another sprocket on the mag wheel. The 32-tooth sprocket made a little difference but if
that engine can idle once the driven-hub is engaged, idle along a flat blacktop road with a slight incline at 10 mph,
that means I can go with higher gearing. I've had a 34-tooth sprocket on the 49cc and it was ok as long as you
gave it a little kick to get going but in high winds forget it. Lynn at MBRebel has a 20-tooth sprocket coming to me
to try out so I am going to see if this one is too high a gearing. She had 24-tooth sprockets and I debated on one
of them but a 20 should tell me if it's too much. The mag wheels are working great on that thing but a fella should
be careful with the torque on the rear fork I don't trust too much power on it. No jackrabbit launches!

More on a post I sent concerning a GPS Speedometer, DON'T BUY! The speedometer:
"IGPSPORT IGS50 Cycling Computer Speedometer GPS Waterproof IPX7 ANT+ Wireless." The vendor
says it's a "GPS" well, it's uses a front wheel wireless transducer that clamps around the hub. Probably the
easiest to mount and better than the wireless spoke mounted units. The add is wrong as far as "GPS" and I have
seen the prices go down on the units EXCEPT for the high-priced "addons". I have the mechanical speedometer
working on the mag wheel and either I will try to use a cellphone or a real GPS unit in the future. I am wondering
if the IGS50 could throw the wheel balance off on the wheel and if it doesn't, it probably is the best unit out there
for fellas wanting to add a quick speedometer addition to their bike.

Dennis. that 212cc engine has a lot of steam and at WOT should be passing cars on Route 66 with that 20T drive sprocket. My Bikeberry Huffy Davidson 49ccHuasheng does 35 on the flat no wind. And climbs Kettle Moraine hills mostly with ease and only the very steepest pitches needs pedal assist. I can see you going down the road smoking like a tracer round.;)

I will probably be running 35 mph at 1500 rpm. (p) Although again, it might take a city block in distance to get up to 20 mph. :mad:
That shipment is being sent out of Century, Florida and I thought Lynn was based in Wisconsin? She said on the invoice that it would
reach destination in 3 to 5 days. I had to cut the 41 chain down for the 32-tooth sprocket and will really have to shorten it up again.
I'll keep you guys posted on when I get a review on what it does if I have time to work on the bike and I still have to get some time to
get some pictures on it. Have a good weekend...

Dennis, I don't know how Lynne is routing product these days. In my personal visits what was not at her Mom and Dad's house is in storage .She may be using Amazon's business model, and retail has always been a hard market. I will buy from Lynne when I can. She really is a very good person. I am lucky to have her so close to me.

Yes, I've done some business with her over the last few years and don't have any complaints! Some of her prices are high
but they are competitive for the market and some of the stuff off of Amazon and Ebay suppliers can't be trusted even though
they have a good refund policy. I had trouble with GasBike a few weeks ago over the drive belt on the CVT which was a
backup. Someone in parts sent a belt meant for the 7G kit. I sent a email and picture to Steve showing the order I placed
and packed up the one they sent and shipped it back. The USPS cost me $7.00 to return it. GasBike then shipped the
one I ordered which I received. A few days later I got a small parcel in the mail and opened it. it was another CVT belt.
Some of the fellas gripe about GasBike but I haven't had any problems with them so maybe their parts pullers need to
be more careful. That sprocket took a big hop yesterday and I got a picture on the tracking I am sending.

Tom and Rick, check this out, I seen the mailman down at the mailbox drop some junk mail and flyers off and in that bunch
was a small bubble wrapped package. The package was real small and opening it, it had a sprocket diameter (tooth-tooth)
of 3 1/2". The package also had two different sets of hexhead-round capscrews (6/per package) of different lengths. I only
expected one package but got two separate ones for disc brakes. The sprocket has a "20" on it and is aluminum. The
machining looked real good so thumbs-up to Lynn! Now, I have to find time to test this out to see what happens the CVT
and engine might not be able to pull the setup and maybe even a belt could fail? I will have to be gentle on takeoff since
the drive system will have to contend with the torque. I know the 32-tooth puts a fella in warp speed quick I doubt that
this one will do that. Might be a "Bonneville-Push-Start" for a little bike speed record on a blacktop!

Caught a fella riding a street bike on a County Road over here he was riding it about 10+ miles for exercise. He might be a part
of a group that rides over a thousand mile course. I talked to him and clocked him at around 25 mph he had a GPS that said he
was averaging 18 mph! He probably runs faster than I do on that road since I keep it at 20-24 mph. I had to run 35 mph to catch
him when I first spotted him about 1/4 mile on a side road. We talked for about 2 miles and when I first caught up to him running
side-by-side, he said "that's cheating!" :D I caught another fella last week on a recumbent bike running about
30 mph (no motor) of course! I would say it's nice to see people moving around on these bikes! (^) I use to ride a 10-speed
20-25 miles a night but I doubt if I could do that now. I suppose it would take me over a month to work up to something like that now if I did it gently and not over do it. I worked it up to that about 10 years ago but did it in
gradual increases. Trying to do now for even a 20 year old could bring on a heart attack let alone someone
my age! The 49cc is a good one for a workout, shut the engine down and peddle! :D

Dennis I like your spirit of try it and .see. I haven't built a 4 stroke with CVT on a bike yet, but have done various go karts using both. The CVT is a game changer for final drive sprocket size though. I'm pulling for the 20 tooth to work for you, but that's pretty small.

I bought a Lifan 4 stroke vertical engine, think it's a 99cc, 3.5 hp about a year ago and put a comet CVT on it...bolted the thing down on a work bench and ran it for a couple of hours over the course of a few days to break it in. It's been waiting for me to get back to it ever since. I thought a 44 tooth would work with the CVT, my 175 lbs. & our hills, so I'm interested in what you find to work with the 212cc.though the Lifan has much less power and torque than the Predator 212.

Rick, respect a engine that has a 3/4" crankshaft. The CVT on a 79cc engine can break the crankshaft from what I have
seen (online) the reducer from 3/4" to 5/8" was used. The question can be assumed, did the user run full power to the
CVT? There are idiots and trolls out there and many times they can be debunked. You and I know how what to look
for on torque/feel and sound. Idiots will jam the throttle wide open and are oblivious to the the mechanics and outcome!
You might try this setup for a CVT, the fellas used a 1" drive system on a driven 5/8" driven CVT. The adapter was
turned down to 5/8" to accommodate a the 1" shaft. This might be a big problem since a CVT could cause enough
drag on the drive and 5/8" crankshaft breaking it. That's probably why GasBike sells just this transmission. This
transmission is special!
