Egli-Vincent Project

admin

I made a start on the Egli-Vincent Project today.I cut out the top spine and machined the steering tube awhile ago.The material is SS 316, 4" OD .065 wall for the main spine/oil tank. I left the wall .200 thick on the steering tube.The initial plan was to leave some meat on the bearing pockets then do the final machining of these on the mill after welding distortion had occurred. This would require quite a bit of setup to get the tube aligned so that the mill cutter ran true to the tube.In the end I chose to turn the pockets to finished size on the lathe before welding.I then made some 1/4" steel bungs that were a tap in fit in the bearing pockets. These worked well to hold the bearing pockets round during welding.The GSXR steering bearings tapped in perfectly, same as before welding.Glen Attached ImagesLast edited by worntorn; 11-26-2010 at 12:42 AM.
Reply:Wow, an Egli Vincent project - please let us in on the details...Do you have any original parts?How much reproduction, how much high performance? (I'm  assuming its a new build, not a resto)What frame  / engine / suspension, and everything else?I'll be keepin an eye out for pics...XMT 350 MPA Dynasty 280DXSuitcase 8RC / OptimaSpoolmatic 30AThermco Ar / C02 mixerAssorted O/A gear
Reply:There won't be very many old parts in it. The engine is going to utilize all of Terry Prince's high performance stuff and will be bored and stroked compared to an original Vincent. Displacement will be 1350 CC.I don't know what the output will be yet as the heads are Terry's latest batch , only tested on his Bonneville bike.I have heard that his Bonnevill bike makes 140 RWHP and about 120 ft. lbs torque. It is also 1350 cc.The front end on my project is from an 03 GSXR 750, as is the back wheel and possibly the rear mono shock.This will differ from an Egli replica quite a bit in that I plan to use mono-shock rear suspension very similar to an original D series Vincent. Ken Horner has done this on the bikes he has built. One of his bikes won the "Battle of the Twins" at Daytona last year.It ran against modern bikes including a new ducati 1198 superbike.I figure I Might as well copy the original Vincent rear suspenson, but reduce the weight some.  The D Vincent is what Yamaha copied when they "invented" the Mono Shock system in the 1980s. They even hired an elderly ex-Vincent Engineer to help them with the design.For now I might temporarily install my 47 Rapide engine in this project, as the rapide is apart for some cosmetic fixups. It could take a year or so to get all of the parts from Terry.It is somewhat dependant on his ability to produce and somewhat on my ability to pay!
Reply:Wow, one of my favorite bikes - I'm subscribed. You must be from down under I'm guessing. Nice weave on the head tube too. G
Reply:I'm from Vancouver BC.I've been dealing with Terry Prince via email. Terry lives somewhere in the bush in OZ.In August I tried to order more parts for the timing chest, but Terry was busy getting ready for a holiday, said he would deal with it when he got home.In September my Wife and I drove down to the US Vincent rally in Kanab Utah. We didn't ride the Vincent down as we had only two days to cover 1350 miles. 400 miles per day is about all I like to do when riding 2 up.So we drove down in the F350 with the Vincent hanging off the back, then went on some great rides out to Grand Canyon, Zion, etc.The funny thing was when I first pulled into the little Motel at Kanab I saw this lean old guy walk past the back of my truck with his head turned looking at the Vincent.It was Terry Prince, I recognized him from the photo on his website.It turned out thatTerry's holiday was another record breaking Bonneville run with his sidecar bike. After Bonneville he stopped by Kanab for the same Vincent Rally that my wife and I were attending.I wish he had brought my cams along!
Reply:Although I appreciate the awesomeness of all vincents, I am not a diehard, therefore I am not familiar with the name Terry Prince. Does he use original engines (case / block / head), or does he build his own components? I'm salivating over future pics already...JasonPS yeah, where are you located anyway?XMT 350 MPA Dynasty 280DXSuitcase 8RC / OptimaSpoolmatic 30AThermco Ar / C02 mixerAssorted O/A gear
Reply:I'm in Langley BC, a suburb of Vancouver.Terry restores original Vincents plus builds specials utilizing his own design improvements. Every now and then he makes up a number of complete Top end kits.These are available in 92mm bore and also in the standard bore of 84mmHe also builds custom cranks in standard Vincent stroke of  90 mm and also 92, 94 plus bob weight race cranks in 100 mm and 102 mm . He is building a 102MM race crank for me to use in this bike along with the 92mm Top End kits I got from him.The heads in his Top end kits have evolved over the years. I think each time he goes to Bonneville he changes the combustion chamber and ports a little. I've got his latest design which uses a bathub shaped combustion chamber with a squish band and is about 10.5 to one compression.  The ports on the original Vincent are 28mm, these are 38mm.The finished engine will look just like an original Vincent and hopefully sound like one, but power is much greater.Terry is for Vincents what Carol Shelby was to the AC sports car.
Reply:made a little more progress on the Egli. I had to make some special offset head brackets in order to mount the engine in the correct location to allow for the wide rear tire.Next is to line everything up then make up & weld some engine mount tangs to connect top spine to the engine.Glen Attached Images
Reply:Man, that's a superb project! Egli Vincents are mythical beasts, a bit like a Ferrari Breadvan or Jag D types. I'm going to have to follow this thread to see how it turns out. Nice work.
Reply:thanks Angus.Will post pics as things progress.Glen
Reply:Just a few welds remaining to do and the frame is complete, swingarm is next. I did the small dia. thinwall tube saddle welds today. It's not easy finding  a good postion for all the tight angles. The welding helmet sometimes prevents a close view.The rest of the welding is a bit easier to get at. Attached Images

Reply:thanks Guys, will keep the photos coming. With the cruddy weather putting a damper on outside activities I'm getting in quite a few shop hours. hopefully I can keep at it!Glen
Reply:Seeing builds like this is the reason I am going back to school.  Keep up the great work.

Reply:It's so nice to see that metal shaping/forming isn't dead, keep it alive and PLEASE teach other people the art! Excellent craftsmanship and work, please keep posting progress pictures!
Reply:Stock Gixxer rear wheel, I'm diggin it.
Reply:I like the wooden safety blocks on your jack too, slick touch to avoid disaster!
Reply:What's the weight going to be when you are finished?  She's an amazing ride.
Reply:It's 330 lbs. as it sits, spot on for balance at 165 front and 165 rear. It should finish at right around 360, about 30 lbs lighter than a Gixxer......however,I might be able to get the crankcases and covers cast in magnesium which will knock off 27lbs, so finished weight then will be around 335 about like a typical 250-350 cc street bike.It should move along smartly with a ten and a half to one 1360cc Vincent pushing it!My son-in-law calls it the "Vincent Funny Car"Glen
Reply:Wow, that is some damn impressive fab work.Can't wait to see more!!!
Reply:Any updates on this project?
Reply:Just realized I left this thread unfinished. I did finish the project. Initially it was run with a/donor engine from my 47 Rapid, the same engine that was used to form the frame. I ran the bike 5,000 miles this way in the summer of 2012 then put the engine back in it's original frame parts.I wanted to see if the bike was nice enough to ride that it warranted building a complete new 1360 Vincent engine. It definitely passed that test, in fact it is the most comfortable and quick handling bike I have ever ridden. I did one 600 mile day on it and felt great afterward, none of the usual aches and pains I get after 300 miles on the other bikes.The weight ended up at 348 lbs dry, tho I may slice another 20 lbs off that with magnesium wheels and some lighter components on the new engine. The new engine is about 60% assembled and the bike should be up and running again this summer.Glen
Reply:wow that like magic taking the crumpled sheet to a perfect fender like that
Reply:Thank god you're still alive. Since you started this I've had two kids, moved cross country and learned to weld stainless. I'm still interested and subscribed so let's revisit what we missed.Gregor
Reply:Gregor, you have accomplished much more than I did in that time! Truth is the build of the bike was finished about two years ago, however the motor parts for the permanent engine are still arriving.The parts are all one offs or very small production runs and take a long time  from order date to arrival. This is OK as it spreads the cost out. The stroker crank was only available from Terry Prince and took two years to show up!The format of this site has also changed, so I need to figure out how/to post photos.Glen
Reply:I don't seem to have the option of attaching photos or insering photos in posts on this/site (using Samsung Tablet) so I will post a link to a blog that has a write up and photos of the build.Glenhttp://egli-vincent.net/2014/02/22/c...odern-vincent/
