Some custom work going on in the "Matt-Cave" :~)

[zenon]

Hey! that frame looks awesome, with the new wheel track around 37 inches and extended wheelbase to 47 inches its going to be a road huger. I like wide tracks but sadly i have to keep my design around 30 inches wide so that i can bring my trike inside my house.

Great work cant wait to see this Tadpole rip the road down.

[TPA]

I wonder how a high power trike would perform with two closely spaced driven rear wheels. Since it does not tilt, they would not need to be independently suspended. You could experiment with powering them together and separately. Assuming of course that traction is a problem.

Kinda like the tomahawk motorcycle.

[recumpence]

I did some more work today.

I removed and redid the rear frame section. This allowed for a much better equipment fit and serviceability. While I was at it, I improved the look a touch.

You can see how LOOOOOW this thing is. The seat hight is 5 inches. The top of the seat back is below the top of the rear tire. It looks too low to be useable. But, it is only a couple degrees lower than my Catrike 700 and I have always wanted that thing lower.

The drive unit has plenty of room even considering the lower seat angle.

This is only a mock-up. The new rims and tires are not on. Also, the rear disc will come off to mount the left side sprocket. I also need to clean up some of the welds (hello flap-disc!). Plus, I ran out of welding wire. So, I had to stop without the welds finished. Lastly, I need to make seat side bolsters (at the hips) and weld battery box mount tabs. After that, it is off to the powder coater to get some serious color!

:: fumbles around for tissues :: ...That is very slick Matt, it is now noticeably wider
with the wheels on that the stock frame but still not 'silly' wide. This will
corner like its on rails! Would liked to have seen a 20x4.25in tire on the back
pitty there are no high quality 20x4.25in rims though :: hint hint :: hehee...
Any chance of a 'Recumpence' stamped 20x4.25 heavy duty rim coming out
from the factory your getting them rimz made mate? I would like a 24in when
you have then in stock too please

Anxiously await the next update, magnificent work Matt...

Hi Matt,

I'm just wondering what technology does Kmx used for their Kingpin is it sealed bearings or combination of sealed bearings and plastic bushings like the catrike design.

Thanks,

Zenon

[recumpence]

It uses large sealer roller bearings pressed into plastic cups that press into the frame.

From my perspective, I think Catrike uses the plastic bushings to add some drag to the steering to reduce the tendecy of headshake at speed. This thing will use a steering damper for that.

Hi Matt,

That is very slick…

Would liked to have seen a 20x4.25in tire on the back…

I agree!

Given your penchant for riding without a helmet I think a full roll cage and safety harness would be a very good idea:

Thanks Matt for the info about catrike and Kmx steering system.

The mock-up looking great, 4 inches ground clearance with 47 inches wheel base would scrape the bottom of the frame in my neighborhood giant speed bumps, I would probably end-up with a skid plate

Not much but here a pic of the tadpole frame I'm working now 49 inches wheel base around 30 inches track, 26 rear rim, 3 disk brakes, rear suspension, still deciding 16 or 20 front wheel and direct or under steering system.

I used to do MIG welding for a living.
I wish I had a TIG.

for the calibre of stuff you're doing def splurge and get a TIG.

Okay, I know I'm mechanically challenged, and although not particularly proud of that fact, I'm not too embarrassed either. In any case, I think I know what a MIG is (a hundred years ago I use to figure out how to kill these... ), but what the heck is a TIG? Seriously, what is the difference?

Gary,
I don't think it was close to a hundred years ago... I dealt with Mig-23s and 29s.

Thanks, Mark. Now I can at least spell them.

Years ago a few from Lockheed were part of a team that helped evaluate parts of a MIG-25 that a Soviet pilot defected with, back in the mid-70s. That beast was all engine, and heavy as hell. Lots of steel, which was surprising to the metal heads. The electronics were "brute-forced" as well, but it had a powerful radar, as I recall.

-- Gary

[rkosiorek]

brute force maybe. betcha it would survive EMP without any fancy shielding, shuttering or turning itself off during the event. the steel used was actually a very high quality stainless. chosen because it would survive high heat but being much easier to work with and cheaper than titanium.

also remember the MiG25 was good to darn near Mach3. was meant to battle the Blackbird. wait the recon version could almost keep up with and hit the same altitude as the SR71 for only a fraction of the price. the recon version even retained a pair of self defense missles. in some ways those old commie birds were severly underestimated.

Yes, no doubt the electronics were not as "glitchy", as most of the boxes still used vacuum tubes, but not very reliable either. The cabling was a mess, and from what I understand, no two aircraft were wired exactly the same. Years later I oversaw Lockheed's part of a joint venture with a government-owned aircraft company in Malaysia. This outfit did maintenance and repair work on pretty much everything that flies in Malaysia. The RMAF ended up with a bunch of MiG-29s, and I remember the AIROD people complaining that none of the aircraft matched the drawings.

Titanium apparently is a bitch to work with. I remember some of the "old guys" at the Skunk Works talking about the tooling and processes they had to invent, in order to get the SR-71 in the air. They never did really solve the expansion problem because that thing would leak from every orifice and joint, when it was on the ground. At 70,000 feet, however, it was tight as a drum.

[rkosiorek]

gary,

as bad as some things maybe were/are. there was also a lot of good stuff there. DOD was so scared of the MiG25 that they invested a boatload of cash developing the F15 and all of its systems to counter it.

i still think that if a well-trained and motivated Russian crew was in one, and it was coming after me..... i would have some major concerns. i believe that many of us here in the west are used to making fun of the enemy cause it makes it easier to deal with it. if we were really as worried as we should be, we would never leave home.

just think it took all of our sophistication 40 years to improve the basic m16/m4 to the point that it reached the reliability that some dumb russian tank sargeant named Kalashnikov managed in 1947. and for years many here in the west laughed about how crudley it was built. ditto the RPG.

any now i am way off topic. i better say something about matt's trike else a moderator is gonna slap my wrist.

nice build matt. i can't wait to see it with the new custom rims after they are anodized. i also love how clean that machine shop is. you can tell this is where precision products are made.

I investigated a fair bit of Soviet kit years ago and it was generally built like a brick outhouse. They had different constraints and enablers to the West, like masses of cheap labour, little access to some materials (like titanium) and a philosophy of never changing anything unless it really needed to be changed (which generally tended to improve reliability). Their stuff may not have been cutting edge technology, but it was bloody effective.

For example, they continued using simple avionics and acorn valves, because they were EMP resistant. They used high strength steels because they had them in abundance, knew how to use them and accepted that this meant less endurance, meaning a need for a larger number of (cheap to build) aircraft (labour was cheap, and the employment was useful). It's easy to look at some former Soviet materiel and think it's a bit backward, but I'm under no illusion that it could have seriously kicked our asses had push come to shove.

Consider it slapped, you socialistic, commie-loving Canuck!

<sorry about crapping all over your thread, Matt. On the other hand, if you want to slap a couple Stinger mounts on the sides of this sick, 3-wheeled bed pan, I think I can get you a few more high-paying customers.

[recumpence]

I am still in my 30s. But, I know about the financial fiasco of the F14 in the 70s. That thing was stupid expensive to develop and manufacture, partly because of the extensive use of titanium and the special welding techniques and equipment used with it. However, the F14 was far ahead of any other aircraft of the time partly due to it EXTREMELY stable high AOA capability. That fighter is one major reason we solidified our status as THE super-power of the time. The F15 was stellar with its over-unity power to weight ratio allowing vertical climb out of the frey. The F16 had better manuoverability than any fighter of its time. It is also a very reliable aircraft, along with a low enough price to enable high numbers in active service. Then we have various other craft that aided us in the technology department like the A10 (ugly, though it is), and the Harrier (super time comsuming to develop, though it was).

These jets put us in a good position millitarily. They also aided us financially (eventually), though we had much debt to contend with because of them.

I agree we should not take the enemie's weaponry for granted. However, we DID have the upper hand. I disagree that we would have been spanked if we tangled with the USSR. We would have lost alot of lives, for sure. But, the attrition ratio would have been very lop-sided in our favor.

At any rate, back on topic!

I will be back at the shop tomorrow doing some more welding and fabricating. I have trying to get as much done as possible because I have a bunch of drive orders to fill soon and that will delay the trike build.

I've heard that. A friend of mine, who has been living in Thailand for about 15 years, has a stunningly good-looking blond Russian girlfriend, but to say she is "high maintenance" is quite the understatement. She has him completely whipped!

[katou]

How will you charge that massive battery? The capability of a large battery like that staggers my mind. I wonder what sort of backpack laser could be run with a battery like that...

"And why would crossing the streams be bad Ray?"

[recumpence]

I got a huge amount of welding done over the last 24 hours. Also, my CNC battery boxes are just about done. I will have some available for sale, by the way.

Anyway, I will post some pictures tomorrow afternoon.

It is looking stellar to say the least!

I think it will be ready for some color by the end of the week.

Oh, hey, anyone know where I can get some 1/2 to 3/4 inch thick foam padding (like the kind kneeling pads use) in black color? I am making hip side bolsters for the seat and I need padding in black for them.
