Tea? Isn't there a law about that where you live? Hi, There is a law about this yes,unless one is a teetotaller !!? Have started on the proper air pump sub assembly and will make it out of brass, I have sawn it out of a large lump !! and as my mum also said 'let the tool do the work' so it didn't take too long !!I have also used the plastic template to 'spot' through for the holes.............I have been using 'small woods decimal gauge and noticed that they used the same divisions from a metric rule to get the thousandths of an inch graduations. this gauge only measures up to 1/8". I thought it would be quite easy to make my own from two rulers to measure wider distances......will keep you posted...........
You crack me up Willy!Dave
Hi Willy, That's looking real cool!Haven't said much lately but have been following along!On the nitrile ball front, I use them in the boiler feed water clack valves on my loco...they work really welll. The only down side I found is that after awhile they seem to either go out of round, or get the seat marks in them. Found this out by chance after having the steam blow back, & replacing them they worked fine for a while longer. While investigating what was going on I did the suck blow test & was getting a seal then no seal! Have since seen somewhere that instead of a nice square faced hole that you need for stainless balls you need to have a taper for the ball to sit in, not sure how much sorry. I guess the idea is to give a bigger seating surface.Recently saw a reference to ceramic balls for something else I was looking at, & think I may give these ago with the square hole to see how they work. My clacks have pressed in seats so not to much of an effort to replace, but Chris's elves while nick them if I take them out!Hi ,thanks for the info, and...is there any info from the manufactures about metal and profiles for these items ??Willbert
