Troublesome Jack Shaft

fingers crossed this is all but finished bearings are pressed in oil seals fitted just needs the bolts trimming and the nuts tightened, it seems to spin nice and true , Im not that happy with it as it is very tight clerances, When the sprockets ware out i will re engineer it and hopefully do a much better job, But for now its good enough.

Progress!

Havent been posting much as have been realy raly busy with the day job, But have made some progress the titanum down pipes are all but done just need to fabricate collector (that was so easy to type!)

AC DC Tig

splashed out on a new and very cheap chinese Tig welder as my geougeous IFL tig is only DC so wont weld Ali, and since the body work is going to be alloy and now the chassis as well ther was no choice this machine cost less than hireing a Tig for 2 weeks, so far ive only used it on DC but it works lovely

Jack Shaft update

Here is the jack shaft thers already a deep grove bearing pressed into the center section, and the 2 needle rollers and then the oil seals will go in each end.

More Anodiseing

Heres my 2nd attempt it was suposed to be bronze/brown as you can see it is not more an iridesent charcole gray, not unpleasent but not what i want!.
Ill try again.

All the way from Kansas

My lovely Buell perimeter disc pictured here in the goldwing rim.This is the perfect solution to my front brakeing needs as i cant have twin disks, Ill have one big one!
I brought this on USA ebay , it only took a week to arive and even with shipping it was way cheaper than the comedy prices UK breakers charge for Buell bits, I have a caliper on the way from the US to which was less than half the price incuding P&P than from a uk breaker.

Home Anodeiseing

Here iam trying to anodeise the jack shaft, its in a bath of sulphuric acide with 12v being past through it, forming hydrogen at the lead cathode and oxygen at the aluminum anode wich combines with the aluminum to form aluminum oxide, accept it didnt as when i put it in the dye tank it picked up no colour , The reason i now sumise is that the acid was way to dilute,
Ive got some stronger now and will try again.

Finite Ellement Analasis (on the cheap)

Thinking about the rear SA and testing the structures the old school way, make a model from balsa and see how much it flexes this is a really good exercise for gaining an understanding of structures, as you can feel exactly how much difference each tube makes.

Titanium Down Pipes

Ive also done some more work on the exhaust this is all going very well, you can see on the table bellow parts cut ready to weld.

I did spend way to long trying to make up some Ti exhaust clamps untill sence prevailed and i just cut of the SS ones from the ER6 down pipes. I built up the middle sections with weld to reinforce them as ther subject to a bending load the didnt originaly have being welded to the pipes.

Magic Casting potions

Components for a tube bender.

Example of pourosity
Been a bit lacks in posting lately as ive been dishartend by my seeming lack of actualy progress, but none the less have still been busy, The firwst couple of Aluminum pours surfeed serious amounts of porosity this is a casting fault caused by gas bubbles result a honeycomb effect not good for structural intergrty, The solution is to use a cover flux and a Degasser, the flux forms a lid on the metal keeping out oxygen and the degasser removes hydrogen fromt the melt just befoer pouring, I also used a grain refiner which keeps the grain nice and small, which is stronger and improves responce to heat treatment.

Whilst i was casting i also made the parts for a tube bender as this might come in useful later on in the build.

Im going to make a basic compression bender and fill the tubes, if that is not sucsefull ive designed it so it could be a draw bender too.
