Hi Thanks Kirk.....I will probally have to leave it up the spring maker...I have several photos of the buggy leaf spring on the Excelsior...It has 3 leaves with 2 that wrap around the main leaf for safety.... I will have to work out the balance weight with a rider at the pivot point of the rear wheel...probally 300lbs with the motor I will be useing.......I am 150 lbs ... but a lot of 6 ft people would be 220lbs engine 60lbs...frame and wheels 60lbs?.....

Hi Curt....I live in a climate where we dont have snowmobiles.....I will have it made as I want to have the 3" wrap around....The Excelsoir pushes the spring up wards I think thats why is has the loop like a buggy spring ..giving a softer ride....give better handling...Waiting on some bearings so I can get on with making the fork head...

A good hardware or Farm supply store will carry replacement springs for small trailers, In fact I saw some locally for less than $20.
But if you want the authenticity and extra cushion of a Excelsior/Indian front return style you will likely have to have one custom made or use a actual antique.
Spring making is a real art form & not easily mastered!
However with the talent exhibited here daily it wouldn’t surprise me if someone answers, “Hey I can do that!”

I am going to atemped to bend my own I have allready made a fourm to bend around. I have seen old car guys bend springs through the years and had good luck with it. Some of the snowmobile springs that I got were bent perty good just from hitting something..............Curt
Hi Curt... I would worry that if I sold it in the future that it would break and kill someone...I have bent and rolled springs as well ..they crack where you heat them and you cant see it ..thats why they have several heat proccess's so this dont happen...they also dip the spring in oil while its extremly hot as well....if the spring is bent on the snowmobile it must have a soft setting ..I had tipper trucks for 25 years ... the springs would clean break..and you could see the rust crack where it snapped......
Have been working on the rear fork ends and roughed out the front fork rockers...I will use the milling machine to finish the contours off...got the bronze bushs for the pivot points and the head stem bearings....these are nice have a seal that sits on the back of the bearing sleeve....

Hi...Have done a bit more...got the fork head tube cut and have machined up the two carry bush's to hold the taper bearings on each end of the steering tube...still have to press the bush's onto the tube and taper them from the bearing cone to the steering tube...You are probally saying ..why are you using this size bearing..25mm ID-49mm OD....I wouldn't use a bicycle bearing head set on something with a V twin can do 80 to 100 MPH...The Yamaha V 250...will do 100 MPH and this bike will be lot lighter...Once I have this completed I will make the sleeve tubes to weld onto it at the correct angles for the frame tubes..I will make the rear frame triangle first ..as this is the usual way to build a bike frame from scratch...Have to give some thought for a jig to set it all up in as I progress...
Received some tires to day for my 21" rims...a pair of dunlop 3.00 21...These look like a a smooth road tire with very small groves ..they will be overall 26 1/2" in height...works out a lot cheaper than importing Simplex....

Hi...Have finished the machining of the bearing carriers for the steering head....I will sweat braze these into place...I have made one slightly bigger ..I will use this on the bottom of the steering tube to take load from the forks...

Looking good DareDevil, it looks like you have hit the ground running. I would kill to have access to a lathe.
Hi Lurker....I had a 12 " swing lathe but had to sell it when we moved recently..as I dont have the workshop space for the bigger lathe.....I am getting by with this benchtop lathe ..it half the size and is slow as you can only do small cuts at a time...Have cut the front frame sleeve tubes in milling machine using hole saw to cut radius and angles...cut a template just to get the angle right...will cut a better shaped brace when I tack it all to gether...

Hi ... Have cut down and resized a yamaha (gt500) steering shaft to suit my frame head...needed to machined to the shaft to fit the tapered roller bearings I'm using...I can now start to do a drawing for the forks steering head plates....also have been setting up a jig to make the rear frame triangle.....

Hi Mightyboosh....A lot of these firms have their parts manufactured by outside contractors..and its a waiting game for delivery...if your worried I would email or better still phone them and talk to the owner of the firm and find out when you could expect a delivery.....there is usually a reason behind slow delivery of parts......
