TT2 Replica build

Speaking of your line of work Sam - i read in the Falkirk Herald that there was plans to turn part of the old Rosebank Distillery into a craft brewery - might be something there for you?
 
Nice work ur doing there m8, nice to see people who still have a skill putting it to good use.....any updates on the build..???
 
measurements

Hi Sam
I've been reading your project with interest having only discovered it this weekend. I'm collecting parts to build a simular project but a TT1. I was looking at getting a frame from Redfox but after looking at your methods I think I'll give it a go in building my own frame. Do you have any measurement and head stock angles that maybe of use to me?
Kind regards
Steven

Hi will look them out, remind me if I dont give to you by next week kinda hectic with work lately.
 
Wheelbase rake and trail in here http://pics.domdummaste.net/ducati/r_pantahs.html I set mine to 26deg and 105 trail with 55" wheel base i think the TT1 was 58" and a steeper head angle but with speaking to Derek Chittingham (Hejira) I decided to stick with the 26deg, tube I use is T45 (Elmdon metals) more forgiving tham chrome molly when tig welding I have seen cracked headstocks on sidecars when the chro/mo had not been normalised properly.
 
I've got an 900ss frame that I was thinking of using to base the gig around. The Haynes manual says that the wheel base is 1410mm and the Ducati website says that the TT2's is 1400, so thats near enough. Plus that front wheel is going to have to miss the front cylinder. I'm going to build it using an early 900 engine, the one with just one ignition pickup. The rear head is away in New Zeland with Sports Motorcycles to have the porting etc reversed. Head length is 5mm more than the 750. The front end is off an early 851 with M1r forks. Wheels are 18 rear and 17 front. I've got most of the running and cycle gear. Now I need a tank the body work and of course a frame. Making your own will be a good saving as prices are £1300 / £2500. 4130 is £10 per foot. I was thinking of using the steering tube off the 900ss frame. Do you know if its ok to weld 4130 to this?
Cheers Steven
 
I am not a metallurgist and not sure what material the ss frame is made from, but speaking to the guy at the supplier for the difference in the yeild of the material compaired to price or cro/mo (4130) to T45 I did not see the benefit to go that route as this is only intended for road use. i can say that T45 is compatible (due to a conversation with the supplier) with welding dissimilar metals ti T45. P.S. make sure the frame you are going to jig is straight....! :)
 
The 900SS frame is made from ALS-450 chrome-molybdenum steel, elsewhere quoted as 25 CrMo4. That might mean something to you metally sorts.

May interest you Derek, playing with 304 st/stl at the moment or should I say any "spare" moment.

100 ltr / 24 gallon nano/pilot brewery for myself. :)

 
Ooh! I like that Sam. :) Is that a HLT, a boiler and a mash tun? What's the keg converted to do?
I'm currently about to help a friend build a nano-brewery using converted beer kegs. He has someone who can do the welding but he has never brewed a mash beer.

Yes all of the above the FV was not in the shot which is the same as the rest. The keg was a FV I did 4 for a crowd that do brews for events where the client comes in and makes their own beer under supervision.
 
I always thought that the 900ss frame was just plain ERW. If its crome moly then it should be ok to weld with the T45. I've just spoken to friend that builds race cars and he said that they use T45 to build the chassis.
Now I do like my real ale. Thank goodness we have more brewerys in west yorks than any where else.
 
Only the Verlicchi frames were chrome molly as far as i am aware ??.
Do you have any idea what a 900SS frame is worth ?, the last one i sold i got £1500 for last month. a repro now is near £3k. Seems a bit daft to cut it up for a head tube. It would probably finance a complete new frame.
 
Oh sorry i came in here half way through !! coincidentally i had just been looking at the Harris TT2 frame on their site as i am after one of their old magnum style bevel frames..so had bevel and TT2 frames in my head and forgot all about the belt drives :)
Sorry....i will shut up again :)

I've no idea what the bevel frames were made from but the frames for the belt SS and the 916/748 are stated as being made from Chro-Moly by several sources including Ian Falloon and Mick Walker.
 
I have heard that the 900/7750ss frame crome moly, then I've heard that its not and they are made from mild steel ERW. This is because cro-moly is a lot more expensive. I'll let you know when its cut up after the gig is made. Then its going to be a base for a coffee table.
 
Hi Sam, can you remember what settings you had your tig set to and what type of filler rod did you use? The exhaust looks good too, what type of tubing did you use for it? Regards Steven
 
You are probably already aware of Two Wheel Classics, they are big on belt drives.

I must admit, they are very tempting; Before taking stock of my finances I costed one out a few years ago.

Less work & hassle and a lot easier. I do understand if you have the skills it's great to use & demonstrate those skills. If you take that route, I am looking forward to seeing the end result.
 
Yes, I've been over to see Jim and I'll be getting my fuel tank and probably the body work off him. You can also get frames from Red Fox Grinta, Dm in Italy who make mini moto bike and Ducati frames as a sideline plus others. Red Cox are cheaper than two wheel classics plus thier frame are crome moly while two wheels are erw steel. I look at it with my Yorkshire view point. I'm not paying another man to do some thing I could have done. I've done gas welding and mig, so after a it of practice hope to be good at tig. A new dc tig is £400 and the tubes will be about £200. A good saving on Two wheels and red foxs prices. Plus you've got a welder at the end of it.
