If these are for a planner I guess that owing to the speed these operate at you will need to ensure the lengths are identical otherwise the blades will be out of balance, which will cause problems.

Could they be bridge reamers? **LINK** I have used them to align holes for riveting, but we are talking full size locomotives here.

Is that a BBC film crew for Bang goes the theory? If so any idea when it will be on?

Thanks for all the replies, it seems that one is not better than the other in a major way, almost it is a matter of personal preference. I will spend a bit more time pondering before doing anything.

Baldric.

Thanks for the responses so far.

I will be actually making a ball on the end of a rod for a steering joint, but can alos see it being usefull when making globe valves and other itmes that need to loo pretty.

Mike, I can see why you ammended the tip holder, it looks very good.

I am going to need to turn some balls in the near future as will need to make or buy a tool to use on my lathe. As I see it there are 2 types:

1. The up and over type where the axis of rotation is horizontal, this seem would fit in a normal tool post with no changes to the lathe. Picture from Chronos **LINK**here
2. Round about type, where the toolpost is replaced with the tool, probably the whole topslide would need to be replaced. Picture from RDG **LINK**here .

Which is easier to use? Looking on youtude option 2 seems easier as once the the ball diameter is set it can be left and just use the cross slide to feed in to the work.

Is one type more flexible than the other? If so why?

FYI I have a Boxford so will be looking to use it on that.

It has been suggested to me that one of the granite type kitchen worktop savers (chopping board) you get in a supermarket for about £15 are ground flat, this has seemd to be true with the one I have.

But some companies add it later because they sell direct and delivered. I tend to create an order and go as far as finding out the total price, using that as a comparison. Some firms will also add P&P once rather than adding it for each item, handy if ordering many items in one go.

I think there was an article recently in either ME or MEW that detailed the meaning of the codes for the tips, the first few items include the tip shape, clamping method and size, after that I think is material but that may be manufacturer dependant. In theory standard tips of the correct type should fit any tool holder,

From my limited experience I have found that the easy way of seeing what tip a tool uses is seeing that suppliers part number. I also think that limiting the number of tip types you have makes sense. I have a couple of tools that use CCMT9 tips these are 100 degree diamond shaped, one of the tools uses the other 2 corners to get the most out of the tips.

Do clubs appreciate people who only turn up for a boiler test or are they deemed as people taking advantage? I am asking this seriously as if that is the route I go down I don't want to upset people.

I do note that there is the "model road steam vehicle society" for me they may be a better bet.

Are there other groups around who club together to get several boilers tested in one go to share costs?

As I said for me this is in the future so just hopeing for information at the moment.

I am no where near the boiler stage yet but it is because I would feel that I would be taking advantage of the free facility and not putting anything back in to a club that I may not join one, however I am not sure what I will do about the boiler inspections. If I had more time than a few hours on odd evenings during the week the matter may be differrent. What are the other real options open to someone who can't or doesn't want to join a club?

PS it is because of this and not having room for a track that I decided to build a road vehicle.

if it is similar to the major then the black knob in the middle of the course feed is screw in to engage the fiine feed, out to disengage.

Looking again not sure why it would have a dovetail on the bottom though unless is was modified for use on your mill.

It looks like the support from a shaper, these add additional support to the table, see here and here

I think you will find that the valve covers on standard GWR cylinder blocks are fitted like this, occasionally you do see a gasket but it is loose so does nothing!

It now works on Windows 7 with IE9, when I tried about an hour ago it didn't!
