Measuring a I/d

[BelgiqueB]

What are slip gauges? I googled them but it was gauge blocks that came up, how would you measure a bore with them?

Same thing.

Same thing.

How do you measure a round hole with a square block?

 

[Seadog]

What you need are gauge pins.

This is a cheap one internally, really poor finish.



If anyone finds themselves deburring one remember that its most important that the slot remains parallel to base any taper will allow the gauge to move towards the narrower part.


I really believe there is a place for someone to make these well and make a profit

I’ll take one of mine apart now

What out they are a **** to reassemble. The inner spring likes to spring

I have a set of micrometer bore gauges but they don't go small enough for under 1" they come up on ebay every so often. They're better than the spring type, you don't have to transfer the size to another measuring device. If you do a lot of boring they are good investment if not the spring type are quite adequate. I use spring leg callipers and and a mic more than any other method.

With bore mics and patience its rather easy to extend your capacity aswell, i have a handful of lapped extensions.

Can't remember the last time I used the bore micrometer, anything over the 100mm max of the 3 point bore mics I have and I just use the telescopic one.
If it were metric then I would likely use it more but it is Imperial and I can't be ersed converting

I'm the opposite to you I convert everything to imperial.

You monster

I think its an age thing.

@bR39Da this optical punch is tesa its brilliant and perfect in the hand.

Thought id tempt you.

ESAB went like that once the Americans got involved and now pedal Chinese stuff no where near as good as machines they made 20 years ago.

Or want an absolute fortune for a water cooled tig torch with their own specific consumables.....So buy a Parweld one which fits the machine, just a different colour (but with a swivel head), and also takes standard WP consumables.
Dunno how much truth is in it but a rep says Parweld make the Esab torches. (Same as Binzel make the Lorch torches?)

You're all the same you welder reps

 

[Welderpaul]

To be honest I don’t think you can go wrong with the Lorch torches. They’re Binzel and nicely made.

Yes, they seem to last the distance with us. They only way we kill them is dropping something heavy on the lines or getting a coolant leak back to the torch which fries the PCB in the torch body. Wouldn't be without the Powermasters now.

Anyway, OT.
