Challenger SR1A vs Jensen 25We ran the Fairground with the SR1A Challenger instead of the Jensen 25. It went faster than the Jensen.
This is the Challenger. 
This is the Jensen |

All I can say is I am glad I was not on any of the rides being powered by the Challenger. Seat belts, harnesses, safety nets and sick buckets and bags are the order of the day.

Wow great videos Andrew!
Great to see the mamod outperform the Jensen 
Wouldn't like to be on that Ferris wheel though I'd end up quite sick

Did Mocha survive.

| Les Marsh |
Both videos are very good and I bet you cannot wait to get a permanent set up.

Mamod simplictiy at its best
my sp6 goes very fast and all which i why i may at some point buy a dynamo (mamod made of course) for it to have ago with

Still waiting for a backordered Striker. Already discussed it with my Millwork guy. Now we're looking at Sausage Makers and other ideas from STIA. We'll get there eventually. |
||||
| Les Marsh |
Thats the problem, it doesn't stop at one.
|
||||
| TRAPPERKEEPER |
Such power!!! These new Mamods are a force to be reckoned with
|
||||
| Mamodman123 |
They sure are! When fully open the power is immense!!
|
||||
| IndianaRog |
Andrew, great videos and no question the Mamod would out do the Jensen in launch potential. That ferris wheel was going so fast you couldn't pick out the seats!!! I would normally say "kids, don't try this at home"...but dang, you ARE at home!!! | ||||
| Minor1PJG |
I feel a bit dizzy Andrew 
Great video

The rpms really do it, Mocha begs you not to get a Jensen 70.
Too bad you cant get the dimensions of the striker and get a head start on the layout. |
||||
| Les Marsh |
I have got those if you need them.
|
||||
| bessytractor |
lol I like that
thanks for sharing! |
||||
| kusuchi |
I can get the dims, John, but its not the same as having it here. Only then do you get the feel for how much space it's going to need to look right.
|
||||
| johnreid |
True, arranging them to look the best is best with all of the components at hand. Leave room for expansion though.
With all serious thought, to make a Fairground display, a Showmans Engine would be the better choice as few were run off of stationaries. The Showmans kind of goes with the theme. |
||||
| kusuchi |
Which we have. May have Andrew try the layout with the Wilesco tomorrow. The Millwork guy who is going to build the board is extraordinarily talented. I am looking into acquiring some scale brass handrails for the perimeter. |
||||
| johnreid |
Breakneck speed shouldnt be the whole thing either, I think one needs to find the right speed to both animate but not just spin out of control. There again you have several engines that you can use and some of the fun is trying the different ones. | ||||
| kusuchi |
I agree. I think your idea about the showman's engine may be the way to go. It will be the most authentic in style, speed and scale.
The Challenger may give the Ferris wheel orbital launch capacity but, while entertaining, that is not what we're aiming for in the final layout, |
||||
| Nick |
I agree, the showmans is the way to go on it.
Very impressive videos, but you have to admit, the Jensen looked better running it. 
Which one do you like better Andrew? (please say Jensen)
|
||||
| Wallace |
Excellent videos.
Very interesting to see the power difference
Closest engine I could compare to my CHallenger was the Jensen 75, and the Challenger seemed to be more powerful than that (without any testing done). Thanks for posting them
|
||||
| Minor1PJG |
The showmans would look great running the fairground

Speed and power are not necessarily the same. I think the fastest engines I own are Oscillators. | ||||
| Mamodman123 |
True but piston valves are generally more powerfull. My TE1V runs a hell of a lot faster than an oscillator, the whole piston is just a blurr!!! |
||||
| johnreid |
Trying to discuss, not argue so please do not take it that way, here is my Jensen 70 at 1/2 speed, that thing just goes. I do not know if it has the Horsepower that my 25 has but it sure goes faster.
I appears that the Mamod Valve has power and speed, that is interesting. |
||||
| Mamodman123 |
I'm not arguing john
I see what you mean, that thing sure does fly
|

Always knew this thread might be a little controversial but it's getting worse.
Andrew has been cleaning and oiling the Jensen 25. He dismantled the sight glass only to discover that one of the hollow screws was completely blocked. Now cleaned, reassembled and thoroughly lubricated I was just summoned to watch it running the fairground. If that carousel goes any faster I'm not going to have to worry about taking the boards up to find lost drive bands, etc. The uplift will do it for me. What I just saw would certainly give the Challenger a run for it's money. Impressive.
Still, it's getting the Showman's as the permanent feature. I did, however, have a short discussion with the Millworker on possible interchangeability. The problem, of course, is designing it in such a fashion that the drive belt tension won't move the Mobile. |
||||
| Nick |
Don't let Andrew watch Reid's videos, he may modify it to become the fastest runner you've ever seen.
|
||||
| johnreid |
I was surprised that the 25 wasnt up to par. That isnt to be snobbish as I love my Mamods too. | ||||
| Kritika |
Just seen the Vid
Way to go Andrew....
I bet somewhere in between those two speeds will be perfect, I bet the Showmans is the right speed. |
||||
| Minor1PJG |
The showmans is a lovely engine but the LEDs on the canopy are VERY fragile (easily knocked off  )
It would make a great display though
|
||||
| kusuchi |
How right you are Paul.
At the moment it is my soldering iron that is the great display in the living room. I think I lose one LED every other run. 
Seriously though anchoring the Mobile seems to be the most serious challenge. If we make radiused slots for the wheels, they are specific to only one engine. And what if we want to use a different engine or the stationary? I want a really classy fairground display, worthy of Chris's centerpiece. I know we have the skills, but it looks like I'll have to open AutoCad and don my tattered Architect''s hat for the final design element. |
||||
| Les Marsh |
Instead of putting in slots for the engines, how about chocks instead, with maybe a pin underneath to fit into a corresponding hole on the board? | ||||
| Minor1PJG |
CJW Steam makes spare TE1 axles and brass hubcaps, buckets etc makes chocks that would fit.
They are made from one piece of wood but look like chocks either side of the wheel. They could be fitted to your base with a permanent or temporary fixing

First vision of the thread, Andrew!
This is as exciting as a real carnival! Have you guys settled on a means for immobilizing the Showman's engine? So many ways. Is the board to be flat, finished wood? Or is it going to be covered in "turf" of some sort? An idea of no great value: Make a flat, thin ply or masonite base for the showman's wheelbase, that size, Have this piece incorporate wheel chocks Andrew can make up himself, really, of cigar box wood---or hand moldable epoxy putty. Now, the bottom of this sub-base, cover that with grippy shelf liner material glued on with fabric glue. Result: a fairground set up that can be used with various engines; in fact each engine could be "mounted" to its own sub-base, and all the sub bases are to just plop into place on the main board, in fact, they can be indexed to go into the same exact position every time (no need then for grippy bottoms) if you use wooden pins like corn skewers to index them to the main base. However you do the details, this reader is excited to see the next results! |
||||
| johnreid |
I wonder if a slot in the base that a screw type clamp could be moved back and forth wouldnt enable various engines to be used. | ||||
| Nick |
How soon before you have all the accessories? | ||||
| Manxman |
The best idea I've seen for holding a mobile secure.
First buy some axles and 'screw on' hub caps from CJW (you can mange without but more hassle). Then get some meccano and bend it to right angles. Thread the meccano onto the axles and then screw it down. It can be made to look ok and doesn't stop the mobile being used elsewhere very quickly.
|
||||
| Manxman |
Having seen how long it took the STIA DVD to get to Richard, I figure at least a couple of weeks. Then a bit of repair work, get Andrew to make a flag, and then a first run. We'll be waiting a little while yet.
|
||||
| Nick |
Isn't there also a Striker on its way? | ||||
| Les Marsh |
I think there is.
|
||||
| Minor1PJG |
Ding, the bell rings: You are the Worlds Strongest Man
|

| kusuchi |
Yes, but it's still backorded. The final showboard will be be about' 4' X 5'. The Wihelm Krauss will be the centepiece. The engine section will be designed with chocs, pins and gommets arranged linearly for accurate loaction of different mobiles.. The same area may be recessed to accomodate the stationary engine's mounting boards. The finshed piece will be more of a millwork masterpiece than a realistic scene. We are intending to install the different pieces , on different levels, + or - about 4", using CTW's brass rails and multiple veneers to create a really spectacular if not entirely realistic effect. My Millwork guy is really enthusistc about this idea , and having infected hiim with our enthusiasm for the project, he now has his heart set on creating a minor masterpiece for the forum. Sorry for the shortage of posts Things are getting kind of busy again at work . Don't worry Les., I'll be in touch tomorrow night but as of now things are looking pretty good on ebay.

If you hooked two engines up to one lineshaft, would you get much of an increase in power?
|
||||
| kusuchi |
|
||||
| Nick |
I was thinking both the Showmans engine and the Jensen 25 running a large fairground with two or more lineshafts. 
|
||||
| Minor1PJG |
The Showman's needs to feature, even if only running a musical organ in the background
|
||||
| Nick |
The showmans does need to be there, but would it gain more power with two engines, or would the slower engine just slow the whole thing down?
|
||||
| johnreid |
If two engines were used on the same lineshaft the power would have to be matched, however I could see a slower engine powering the accessories that go too fast and the faster machine powering the accessories that go slower.
I still think that the ability to use various Engines would be fun as new engines get purchased and older ones are take out of service for repairs etc. |
||||
| Nick |
He could have 2 or 3 lineshafts and when one engine is getting more water or fuel, half of the fairground could remain running.
|
||||
| kusuchi |
Thanks Guys,
Some great ideas here. This project is growing by the minute. The Millworker came over last night, he is a very skilled artisan, and now even he is excited. He has all kinds of offcuts of beautiful veneers so we may do the platforms in two contrasting tones. Love the twin engine concept. Sorry not to have responded before but I have two large projects to estimate at the moment
Will post as time permits
|
||||
| johnreid |
Good luck on the Estimates, I know what that is like. | ||||
| Nick |
I hope you consider my twin engine idea and build a large carnival! Your two level idea would top it off great too!
Now you're going to need a dynamo with some "yardlights".
|
||||
| Les Marsh |
You will also need a Cretors Popcorn Machine.
|
||||
| Nick |
By the time were done giving him ideas he will!
|
||||
| kusuchi |
The two engine idea is a must. One stationary, and a Showmans. Looking at a Flieschmann 122/4 on German e bay that comes with a dynamo....... Not so much thinking of two levels as multiple levels with small increments of height difference between platforms for different accessories..
Accessories collection seems to be growing. I need to get this designed and built asap. If not there will be one more item I will need.......a second mortgage!
