Edit
Thank you I can see now

Finished the dovetail tool of this arvo. ended up using 5mm rod forthe legs and sticking it on with some pigeon poo......I had to bend the legs out a bit as it was just to unstable with them straight. It works well, i can consistent readings, turns out my cross slide dovetail is .0013 out of parallel.
I can see with a longer beam it will be a useful tool for testing all sorts of things.

Here are the pics.......i have not forgotten them this time....

Ueee I've just scratched a bald spot on me noggen, can you give us couple of action shots
so I can see how you drive it.

I will tomorrow, otherwise if you watch from about 6:30 on this vid of Nicks you will see his in action. Scraping in a lathe's top slide (with tapered gib) - YouTube

Hi Ewan,
Couldnt you flip everything up side down so the DTI clamp is closer to the styles?*

I wonder why Nick didnt use two pins at the back and one at the front. Woudnt that make it easier to use as the two pins would give you a repeatable location???

Stuart


*yes I know you copied Nick, maybe he had his reasons. Yes I know with a DTI it wont make much if any difference to rigidity.... but it will make me feel better, how could you put a price on that? lol

Stu it looks to me that he only has the one pin at the rear so that it can be moved side to side at the indicator end to find the narrowest point, it wouldn't work with two legs at the rear.

Yeah but, I'm not sure you care if you are spot on the narrowest point. All you really care about is that the reading is repeatable. Guess I should make one and see.

Stuart

I would suggest that 2 pins at the front are for stability,access and reliability of measurement. If there was one pin at the front, the indicator would have to be on one side or the other of the pin which would move the C of G towards the outside of the footprint of the jig. Also by having the indicator between the two pins there is no chance of the indicator rocking while being traversed along the bed. Having the indicator between the pins will 'average' the height that the reading is taken at. If the indicator was along side one pin, the height would be highly dependent on the position of that pin (for example if the pin sat in a pit or hollow). If measuring the side of a V or dovetail this could give the impression of wear when there was not any.

And, I've just been thinking about using this thing on lathe cross slides, were my idea may(or may not) work well enough. But this piece of kit is also used for other ways and as they get wider my idea would I think get trickier to use, unless you moved the two pins further apart. Which would mean different setups for different widths and may well turn a nice little jig into a pile of bits and pieces for no huge gain. Not like many of us will be using it a 100 of times a day.

I still might make one though

Stuart

Well done Andrew! Looks great.

Cheers,

Hey guys this has been my latest project. I explained the go kart pretty badly, got abit nervours and didnt know what to say but o well hahah enjoy!

Finally finished a light for the lathe.
Based on a LED down-light - slight modification to improve contact area with housing.

Casing is an old spray can mounted on a microphone gooseneck.

2 mounting pieces for the LED - one inside the can with a matching taper to the one turned on the lamp and the "fins" on the outside - both from aluminium

Cooper, good stuff but before you go driving it you really need to rig up a chain guard to protect your elbow. Any kart shop will have one you can modify to fit.
