Yes it works fine, I liked the post after watching your vid.Does the link work for anyone because it won't for me

Cheers for that Hood I will post another when I cut the next set with the new indexing plate set up I think things will be running smother hopefully because when I was testing mark one of the indexer things came loose ( all trial and error ) and the cutter jambed and I suspect the chuck back plate took a knock throwing things slightly out I have re machined it tonight so things should be running spot on again

As I am new to machining and lathe work.
Just started modifying a tool post holder to take a new tool post. Nothing to exciting.

Forgot to take picturesbut had to machine 2 new shaft ends for a Westwood powered grass collector sweeper today. The bearings on both ends of the shaft were goosed. The pulley side was so bad there were no balls left in the bearing and it had obviously been run like this for some time as the shaft end was extremely worn. (Note I got the sweeper unit 2nd hand for £30, so worth taking the time to repair). An hour later and I had 2 shaft ends machined up on the lathe. I then had to grind off the weld on the outside of the pulley to remove the worn shaft end and a good pressed in fit for the new shaft end was achieved and welded for good measure.
I used to service lawnmower & without fail every Westwood grass collector we seen had knackered bearings.
It was a very poor design and as you discovered it is a faff to change them. We didn't have a lathe so it was a matter of building up a worn shaft with weld & 'machining' it to size with an angle grinder! 
I would suggest you check the bearings regularly, at least twice a season as they can seize up very quickly. I assume you have checked all the other bearings on the sweeper.
Not sure if you are familiar with ride on mowers but keep a check on the bearings for the drive belt. particularly the guide/idler bearings. They can go from ok to being seized very quickly. If you catch them in time you can repack them with grease, it's a good idea to do that on new ones too. On the plastic ones you have to replace the whole pulley but on the pressed metal ones you can drill out the rivets & change the bearing then use bolts to reassemble it. It also means you can use a good quality bearing rather than the cheap ones normally fitted!
Thanks, it's coming along.
I know I need to make the guard..... tomorrow honest and put a dust extraction system into it too.
As I said all welded up. Spacer made for grinding wheel
Couldn't resist a quick play. Dressed the wheel since then.
and this is what the slot and end mill produced, WD40 to lubricate
Indexing system works well as does the pivot, need to make angle set gauges for the clearance angles, as at the moment they're just a guess. Guard, dust extraction, put some rubber feet on the frame and paint it!
Oh yes make up the guide for grinding the edge.
This is an interesting little Job that came my way as it seemed no one locally wanted to do it. It's A Pneumatic Filter using a 1/4 BSPP x 6mm Body with lots of 1mm holes and A 2mm wide screwdriver slot, turned and screwed on a Emi mec auto lathe. Then the parts are put on a Vmc with a two part setup for the holes and slots. It seems carbide drills are not the way to go with some jobs, this being one of them. The lack of integrity with carbide this small means when the drill breaks through the part, so does the drill! Hss being more pliable and flexible has been the way to go. 600 holes later on one drill which is rather surprising, only another 1650 holes to go! Luckily the parts are brass which has eased the pain a bit.
I have used 5 pence pieces for scale, A mug was a little to big.. even so a 5 pence piece is 18mm and the part 12.9 Diam, 5mm difference just to show how small they actually are. Images can be pretty deceiving at times. I even done a small video at the weekend to keep me amused, it's not perfect but not to bad for a cheap smart phone and an old version of windows movie maker.

Nicely done and I love seeing things like this because it reminds me why I don't do production stuff.
To me that is a very patient man loading the machine, to heck with that
The bit you don't know is that I am actually sitting behind the machine winding a crank handle sitting in a nice comfy chair with beer and watching daytime tv
Long hand was an option if things didn't go to plan. learning patience is part of the training as a youngster. I have done a lot worse than this long hand before... it's a good lesson to learn

Just to reinforce your view of not doing production stuff......below is a reminder. 150 parts complete and a total of errrrr (calculator out ) 2250 holes and totally stunningly, it was all done with one drill and that is not a lie either. It's not really production, the quantities are to low these days. It's just small batch and it really is not that bad to do once you have the job sussed. Its only 75 cycles of the machine.... all be it, it is a bit time consuming drilling holes that small.
I have some other projects to post up when i get around to it... a few of those will make your eyes water!

Production to me is more than a few
I have done that kind of stuff before when helping out a friend when he was stowed under with work. Once spent a week plunging a form tool into many hundreds of nylon blanks to make vee pulleys on a manual lathe, spent another few days doing thousands of slots in the heads of screws, spend days doing triple slots in chain link end blocks. It is not the stuff I like doing and so I shy away from it if at all possible. I like doing one off stuff or maybe 4 or 5's but that is my limit before I start going crazy.

A walking stick connector from brass for one of the old boys at work. 20mm of the stick goes in the ends then they were glued on with epoxy, because I don't fully trust adhesives and wouldn't want to be him to have a mishap I also cross pinned both ends and then blended the pins.

this week I've also been boring out a excavator breaker chuck, the chuck is hardened steel and should be replaced when they get worn (usually through lack of grease) but they are fairly expensive for what the are, so I bore them out and fit replaceable hardend bushings. not a big job but quite a nice little job.
