This time i am going to document the whole build, and i will post as much as i can. Previously i posted a rigid sportster here on the jj http://www.jockeyjournal.com/forum/showthread.php?t=63365&showall=1
This build will contain mostly classic/vintage parts or handmade components.

here it is:


The bike in question is a numbers matching 1956 T110, it has a pre 55 6t rigid hardtail/seat post.


A lot of the beauty in vintage bikes is in the details which I love to capture in close ups


My goal is to build everything from scratch including the rear portion of the frame (you will see why)

.
.
.

Disassembling the engine and cleaning parts to start with


Taking care of the crank shaft and sludge tube


ready for tumbling


the cylinder heads were in pretty good shape, surprised not to see any of those hairline cracks




getting ready to strip the paint


after stripping the paint and removing lots of filler this is what i have found,
A poor frame lengthening job, the tubes were totally crooked, look at the previous image with all the filler on, i call that art work,

.
.

The front end that I am going to use is an original pre war Norton 16H Heavy Duty girder, with the rebound springs,


my favorite, scotch-brite


here you see all that surface rust is removed with sb on one tube, pretty straight for a +70 year front end.


more to come,

Nice Work . Might I suggest "appleply" for future bucks. It's solid, structurally stable and you won't come across any voids like plywood. It even comes in a 1" thickness.
hi bp131, thanks for the tip. Actually the type of birch that i've used falls under the same category as appleply. I worked at a shoe manufacturing r/d facility and we had bucks/fixtures made of this kind of wood.

That gas tank looks slick. And the oil tank is looking great also. Not just another round tank.
I've never done a Buck for a oil tank. Nice work.
REDDOG, thanks.. i'm trying to come up with something not done before, but at the same time trying to keep it style-wise peroid correct, (from the 20's to the 50's, square gas/oil tanks, sluged frames etc..) It is a challenge and lots of fun..

The tank is amazing! I wish I would have did mine more like that!
Thanks Ray,,

One of the nice features of this oil tank is that it will have an integrated oil cooler.
I bent/welded the sheet to make an air duct





The inside and outside of the oil tank and its air duct is aligned to the gas tank for optimum air movement. pix will come soon showing aerodynamics..

Still rough but you get the idea


More technical info/pix are on my blog.

I love to see what people are prepared to do to make something extra special. It would be so easy to just not make that oil tank with the cooler tube in it. Its a lot more work I can see that but a nice touch. Great work.

Cheers Dan.
I can't say anything that hasn't already been said about this build and thread!

I'm hooked, please keep the updates coming!
First image of the new oil tank on the bike.

Thanks a lot guys, I'm glad you liked the oil tank.

Not quite done yet but here is a little teaser ;)

hey 72oifbobber, at this point i'm gathering parts for this project and working on the lsr project. not much time left until august.
here is the 52 lsr triumph on my new bench that i am building for Bonneville..


I have the updates on my blog for this one..

Alp,

What is the trick to mounting the stock Triumph girder to the frame ? I am getting very frustrated and as this time having to use the 20 piece set of ball bearings on the bottom of the steering stem and I keep losing them in my failed attempts to mount the thing.

My frame is a '47 (T100) with a 3HW girder.

Also, what is the steering stem length of your girder and what top bearing set up are you using ? Did you need to do any modifications ?


Thanks
Jon, use some bearing grease to hold the balls in place on the lower race, have someone give a hand and insert the stem and hold it tight while you get the top bearing and top tree etc in place.

Tyler
Girders are always fun to stuff because the spring hits the bearing cup. The easiest way I've found is to mount the lower yoke by itself, then add the blade and links once you've got the stem nut snugged down.

Also, I've been following this thread but don't think I've said it yet- killer bike man. Rigid T110 with a girder- I'm a little jealous.
Thanks Lurkingclass and Tyler.

That spring-spring perch hitting the bearing cup is a major problem. I started out with the stem mounted but that spring was hitting. I was using an H-D bearing cup and roller bearing too..since the stock 3/16" ball race won't go past the threads. I drifted the H-D cup back out and re-installed the Triumph cup but still have the issue of the I.D. of the top race being just a hair to small like .005".

So the stem nut does indeed sit on top of the bearing/dustcover before the top is installed ?

Hi Jon, sorry for the delay, I've been busy the last couple days with my lsr motor, had many issues. Seems like Pete and Tyler answered your question (thanks guys).

"So the stem nut does indeed sit on top of the bearing/dustcover before the top is installed ?"

The triumph girder actually fits as one piece without any issues, but the norton will need some machining on the stem. When i'm there i will document the front end installation and let you know..

Here is my lsr motor, checking out the internal clearances


Dont let its stock appearance fool you, had to machine two crankshafts, modifiy the cases, experiment many bearings etc...
Actually having Wes "Four Aces" right around the corner is really cool when you need some advice, but at the same time he is responsible for all the "Salt" going on here.. Thanks Wes for your time and all the supply, appreciate it..

Sounds great, thanks a bunch! The engine looks good and look forward to hearing the end results on that as well. :cool:

i have a tight schedule so i'm working on two projects. My other bonneville bike is just killing me, I prepped all the parts for final assembly.









In the meantime Doug sent me the magnetos and the generator..
The angry one on the left is my high performance lsr bike magneto :)

They look like little robots! Damn it, I need to organize my garage. That bench looks like a great place to get some work done.
The nice thing about those bucks, is when you are finished, you can varnish them and display them in your living room as art. I would.

You make me want to go out and fabricate more. Thank you.
