I break taps to often to be buying overpriced ones  :lol:

But I can see for pipe fittings I might be "forced" to use ME, but it will be sparingly as poss.... :thumbup:

I very rarely break a tap :- touch wood etc etc, but I think thats down to a baptism of fire I experienced when I was an apprentice. Each group of first year apprentices had a project to complete once they finished there tool kit, for our year it was a model mill engine I had the job of making the governer, when i came to tap the frame to take the governer I broke the tap and there was no way we could get the broken tap out, I took a lot of stick from the supervisors and the other apprentices. The model is still on display in the board room along with all the other projects, I alway sneek a look to see if the tap faries have got that tap out, I still feal embarised about it:- I think thats why I'm so carfull when tapping. Sorry about going so off topic  :offtopic:

Thanks John that's them words I was looking for..... :thumbup:

TBH I'm really enjoying building this so far. It has forced me to re-evaluate the way I do things. I've had to set up the mill properly, "use" the mill dial indicators, and generally think about accuracy and tolerances.

Exactly why I chose to build one in the first place.  :thumbup:

After fitting the vertical DRO and stopped playing with less than half built engines I managed to get a little marking out done along with some plate cutting.

3mm aluminium from and old lab instrument casing. Yet another presy from a kind gentleman up north.



Machining the widths equal







Well that’s about it tonight, surprising how long the marking out takes.
I wonder what all the lines are for  :scratch:

Rhetorical...... :thumbup:
