Boring is really boring

Hi, just a thought.
you dont need a 4jaw chuck to offset bore on the lathe.
I have one but didnt use it to make my offset mushrooms.
All you need to do is put some packing between one of the jaws and the work piece and its offset
i think the packer i used was 6mm you can true up the job using packing between the job and the chuck check in three places and it will be true.
remove the packing between the chuck and job before you run the lathe.
you can check the offset with a clock or a pointer set at the largest offset then rotate 180 degrees and measure the difference.
obviously make sure you are happy that the job is secure before running the lathe.
also you can use your lathe to do the fishmouts on the wishbone tubes but thats a different story
hope you find this usefull

just seen the size of your lathe it might be a bit small for the offset thing above my chuck is a 5 inch one may still be possible but be carefull

Ray, I bought a couple of little books when I got the lathe, and they show this technique.

It's what I was planning to investigate. I had even got an off-cut of the 2" bar I am using ready and waiting to setup to determine the correct spacer size.

Shame the bloody thing has decided to play up, I was quite getting into using it. Might have to buy a mill next as well

mm ive used lathes with 4ft face plates and 24ft beds so yes itis small my lathe is only about a 3ft bed but i did manage to skim the front discs off my sierra on it, but at the end of the day you can still make usefull parts yours hope you sort it out and get back to making bits
ive just made all my suspension bushes and crush tubes
the material cost about £20 ive used delrin for the bushes and 19mm stainless bar from the scrapyard
not polybushes i know but im happy with them

24ft bed!! bloody hell that's a big one

I was going to make my bushes, but got a full set of polybushes with the stainless inserts for £60, so that saved me several hours
