Is right! :dremel:

I've done a lot of that "slightly out" type drilling before, and for that matter a few cases of slightly out milling and turning too.... Quite a few more regularly than I should probably admit to :palm: Anyway....
Usually I take a step back, tell myself off a little, get over it and figure out whether I can continue to use it in a slightly modified fashion?
Same as you have :nrocks: :borg:

Other than the little misfire it all looks to be going to plan :thumbup:

Keep at it Ross, you'll have a loverly little wobbler in no time. (calling Mr Howard, time for your tag line :lol:)

I made the end cap for the cylinder today, It was fiddly to make but I got there.

First I turned the diameter of the bore,

Then I turned the diameter of the part that will fit into the recess,

I cut the material in half and worked backwards facing the length.

I purposely left and overlap on the length of the end cap I was going to make it flush but I decided against it. I put a taper on the cap too.

Here is the finished article:

And it fitted on the cylinder.

I'll have a go at soldering it at the weekend, enough work for one day!

DaveH:
Good job Ross :thumbup: :clap:

Fiddly is good, :) once one can do fiddly things, then you will be able to do anything :)

It is coming along nicely :thumbup: :clap:

Well done! :clap: :clap:
