There are several Eglis in the area. Don't know how many are original or repops.

I believe there were about 70 of the originals built by Fritz Egli sr. Actually Terry Prince built most of those, he was employed by Fritz Egli at the time. Not long after these were built,Roger slater started building them in England. Roger also subcontracted the actual job of framebuilding out to others. As a consequence some of the Slater Eglis frames are lovely while others are atrocious, just depending on which shop put them together.
Terry told me of one Slater
Egli that came into his shop a few years ago. Tho it had neverbeen dropped, the front fork ran 1.5 inches out of plumb when the rear wheel and engine were sitting plumb!

I think Slater sold a couple hunred or so of these Egli "kits". There is one a few miles down the road from me, never assembled but the owner has had it for about 25 years. I couldnt get him to consider selling it so i went ahead with this project instead.

Im kind of glad i did, its been an education rather than just an assembly process.

Got started in on it again yesterday, soritng out the tank , seat pan and rear cowl design.

The seat is a new old stock 2002 Triumph Daytona seat, very light , only 2 pounds, made in Italy. I chose it because it is light in weight, is the shape I was looking for and is quite comfortable, at least for the test sit. After seven hours of riding I might have a different opinion.

The cowl will be built in aluminium and a low skirt will need to run right forward under the seat up to the tank.,so all one unit from front of seat to rear of cowl.

The tank model was sent to me by a friend from Norway, Dag Rise. He is building a traditional Egli rep (skinny spoked wheels, twinshock swingarm)

We both admire the tank on Jos den Ouden's beautiful Egli so Dag and an artist friend set out to recreate that shape in the styrofoam model. Jos Ouden's'tank was built by a superlative tank builder in the UK, Don Woodward. Don passed away a couple of years ago.

I will bolt the seat pan/ seat cowl unit to the upper frame rails, but will attach the seat with Dzus fasteners from below. That way the seat will be a quick detach in order to get at the battery and any other electrics that can be fitted into the cowl.

A SS flat bar loop will continue from where the seat frame tubes terminate. I plan to attach a pair of flexible red LED strips to this flat bar. These will be the rear turn indicators and brake lights. When the are not on they will barely be noticable under the skirt of the cowl.














finished buck, ready for forming

Superb workmanship. Keep the progress pictures coming.

She's going great gunns , youre in another space / time continum,
or got someone to do the cooking .

But WHAT do You make of this ??



Looks like Isolastics in there , maybe . ? ?

Saw Debenham on the Norvin take on McIntosh on His Egli Vin Aeons Ago . Age & Cunning beating youth & entusiasm .
Or WFO beating , I'll try that , but im not to sure , = the escape road / overshoot . Youngh Whipperschappers !

WOW worntorn !! I've been on the site for about a year and hadn't really looked at the "anything else" threads. Glad I did and glad that you've posted you're build on here. I remember reading another thread regarding Jim Comstock's crankcase vent, and this other member asked Jim where he found the time to make these things and he said that he doesn't watch TV. I'll bet you don't watch much TV either. Again thanks for sharing your build. Cj

Matt ,is the bike in the photo a Mcintosh creation? It has the look and colour for one of his. At the start of this project, he was kind enough to send me some very detailed photos of his beautiful Egli-Vincent racer. I ended up with something quite a long way off his more traditional design, but was definitely inspired by his work.

You guessed it CJ, no TVfor me.

Is that new hit show M.A.S.H still on?

Gen U wine EGLi of the ' pics raceing norton ' on confuser ( computor ) . " Fritz Pier " on fairing I think was Eglis R.H. Man . EGLI on computor got " EGLI NORTON = 2 " for numbers , or ON numbers built .

So a real verey Egli Commando , see the Timing Cover .

A decrepid chap got the last two in wrapping fork blades for his Comet ( Vs Car , woman driver . I didnt see him , perhaps not blended in with the scenery , polish didnt come into it ) nevertheless , a humble chap .
He'd gone to London and bought The Egli Vin in 1970 , for 1500 , sold it a few years later , to Mc . For ONE Thou . oh . . . . dear . . . . ?

' Two wheels ' mag here regularly had Euro Tech Interogation articals . . . . off to the shed .

Perry did a inventory of stock , a day or so to quantify all the Vin stuff . mostly small parts . But that was 81 . And it was sold as a Lot . Youd get a R5/75 for 2100 back then , A Ducati 750 sport too , . . . fudge .

Is that new hit show M.A.S.H still on? [/quote] Had too threaten to wring someones neck . He was still whistling the Theme Tune . The other day .

made a start on shaping the tail piece today;

a little more progress with the tin work. Lots of room under here for one of the lightweight batteries and any other electrics.

When the Vincent was made, do you think the engine was placed so that it was centered weight wise on both sides? Do you think moving it towards the right will affect handling? (I don't think it matters much FWIW) are you placing weight on the left or adding lightness on the right to correct it?

Hi Jean

Before starting to build the frame, I gave your question a lot of thought. I decided to aks about this idea on the Vincent forum, since there have been a lot of different Vincent specials built over the years.
No one seemed to know the answer but I did get some other good info from the posters there.
Here is the thread- http://www.vincentownersclub.co.uk/show ... win-engine.

In the end I did some accurate measuring and found that the Vincent engine is offset 9 mm to the left of the wheel/frame centre on a standard Vincent or Egli, he used the same line up. Here Im talking of the centre of the flywheels, which I think should be close to the centre of the wheels in order to have light handling. This way all three gyros are in line. The actual lateral centre of weight of the engine is even further to the left.
In this frame of mine, the centre of engine weight is exactly on the whel and frame centre. The centre of flywheels is a bit to the right of the wheel centre, about as far off as an original Vincent, or Egli, only off to the right whereas those bikes have the flywheel centre off to the left.

All you need is three bathroom scales to check.

You'll need to fabricate a simple "third leg" for the timing side, about the same length as the sidestand; temporarily tape it to the frame where an off-side stand would mount opposite the actual one.

Set both the bike's wheels on scales, and the sidestand on a third scale. Check the sidestand reading. Then, remove the makeshift stand, set it up on the third scale and measure.

That should give you a fair idea how close your side-to-side balance is. Maybe not accuate to the gram, but definitely close enough to spot any significant difference; you can check by simply hanging X, Y, or Z part on one side of the bike and measuing it both ways without moving the part. Remember, not all of the weight you add will transfer to either side, but most of it will; all the weight will be found in the difference in ALL THREE scales added together.

Hi Paul

For an overall balance check of complete bikes I just used a 2 foot level to set the bikes rear wheel up plumb, position the front wheel straight ahead and then let go. The stock Vincent falls to the left quite quickly, can't remember which way the Commando went, but it clearly had a lean. The 650SS would sit there balanced on its tires until a breeze blew it over.
Maybe that is why it is so nice to handle.

The dirt bikes, two Ossas and a 490 Maico, are allso balanced nearly perfectly from this basic test.

For figuring out the centre of weight of the Vincent engine for build purposes (not the same as centre of flywheels, it turned out) I used a piece of 3" pipe laid under the engine lengthwise. By rolling the engine sideways the balance point , plus or minus about 1/8", was easy to find.

I don't think the balance is all that important to the average road rider. I have on occasion done solo trips on the Rapide with one filled 40 pound pannier hanging off the side. You notice it a bit at very slow speed, pulling in for gas etc, however at any speed over about 10 mph it isn't really a factor.
For a race bike though, I would want to have things balanced side to side and also balanced evenly front and rear. A manx Norton is very close to 50/50 front and rear, so can't hurt to follow that.
I was pleased that this project bike came out exactly 50/50 so far. Hopefully I can keep it close to that when finished.

Here is yesterdays effort;
