Jasonb:
I'd be tempted to put it back in the 3 jaw and turn the edge of the flange, that way when you reverse it in the 4 jaw you can use a fixed steady on the edge of the flange which will be a lot safer and should also give a better finish as it will be a more rigid setup.

Other option would be to fix the casting to the cross slide and use a between ctrs bar as its a long overhang using a chuck.

Keep up the good work.

Nice setups Andy.

Take it gently and everything should be just fine. I gather that you don't have a faceplate for your lathe, that would allow, coupled with your angle plate, safer and more rigid setups.

Just remember that you only have one go at it before more expense drags it's a**e into the equation.

I am glad you have realised that working with castings is not the same as nice, neat and easy barstock. Sometimes it seems like you will never be able to hold it safely and rigid enough, but where there is a will there is a way, something always pops up.

Don't ignore good advice that is being given by other people, they are not trying to take over your post or be smart a**ses. They have most probably been thru it all before and can let you know about the pitfalls and successes, and it could save you a great deal of time, effort and maybe money in the long run.

Machining castings is totally different to normal run of the mill stuff.

Looking good.

Andy.
The more I see, and admire, your set up struggles....... :clap:
The more I am pleased, my R/E came to me as an orphan. With all the large awkward parts done.... I hope! :thumbup:

Work will commence, one day. When other commitments are sorted..... ::)

Love the rotating base, positioning fixture thing, you used.
Great work...... Keep it coming on..... :D

AndyB:
Thank you for the kind words chaps. :nrocks:

Thanks Bogs, I am always ready to take advice...that's one of the reasons I am putting up the project log and showing my difficulties! I have got a faceplate but can't think how to mount the cylinder on it...any and all suggestions, both polite and humourous welcome! Unless...I make up a collar to go round the narrow towards the base and tie it to the faceplate with rods and bottlescrews, with blocks to adjust and keep it steady against the faceplate.

Thank you for the fixed steady tip Jason. Unfortunately my original Drummond fixed steady is 2.25" across the throat and the finished size of the cylinder end is 2.276". Original fixed steadies are rare as rocking horse...er...stuff, I bought a whole lathe just to get one! I dont want to cut it about. Hmm...The old boys used to use bits of wood quite a lot. I've got a little pamphlet from the '20s showing some of the things made on a treadle Roundbed (9 cylinder radial engine etc). It has some weird (?) setups there, might give me some ideas. Thanks again.

Hopefully future progress will be a little more swift...but don't hold your breath for the next installment, it might be terminal! :lol:

Jasonb:
Its easier when you have a flat surface to go against the angleplate but something can usually be cobbled together.
