Re: L.E. American & Feedwater?

in general, you do NOT want an o-ring on the ram AND packing round the ram where it enters the body.

you will only build up pressure between and cause one to blow....or leak steadily

Re: L.E. American & Feedwater?

Good luck with cramming an axle pump in there.

Properly done axle pumps have no more problems than any other part of a steamer...been using them for decades.

I am confused - If you added an injector...are you STILL having problems keeping up with water?

Re: Thread Milling

That's a good example of tangencies...but care that you wear offset cannot exceed 0.0001 -> which may not be enough

Re: Thread Milling

This is a case of the control not knowing what to do with cutter comp as described earlier. You might find it easier tp use G42 and put in a negative value for the offset. Some controls will handle it better. Another way to handle this is to break it into quadrants..some controls handle the LOOK AHE...

Re: Thread Milling

SOME controls, when activating G41/G42 and going directly into a series of more than 2 arcs (as you are here) at a sharp included corner, 'loose track' of where they need to begin without having a Y component in the initiation line. It is better (for the general control case), to initialize cutter c...

Re: Thread Milling

DI or D1?????

Cutter compensation can be either for wear or full radius offset.

If doing wear, then the lead-in / out can be quite a small number because it only handles the difference between the programmed and actual tool.

The last time I was in Reeves, they were in the middle of shipping an entire set of loco castings (7-1/4" I believe) to a fellow in the USA.

Re: WTF is wrong with shipping to Canada???!!!

Re: welding boiler

It is my understanding that there are now MIG procedures for code welding that requires very specific rod and procedures and certifications.

Never seen it done - but that does not mean that it cannot be done.

Re: gun drill oil feed

all gun drilling that I have seen / supported / programmed is done with a hollow drill and the liquid coming down to the cutting face, flushing everything out from the bottom of the hole. I have never seen a spraymist being used for gun drilling, but then have never seen the need for it since the sy...
