Aggghhhh - I've just sat here and done half a post only to hit the wrong tab at the top and lost the bloody lot - aggghhhh double bloody aagggghhhhhhhhhhh!!!
Hello guys - hows it going
Well I'm happy to say I'm near back to normal and have finally had some decent time in the old shed
. I began by turning that piece of En1a into a length of 6mm walled tube. That dirty swarf covered blob on the tool is a lump of sticky blue tack set there to take the resonance out of the tool. It doesn't always work but on this occasion it did. It won't stop real chatter but it helps and in this instance took out the ringing and the fine chatter marks that had resulted.
The end caps were turned from slices of the same material. The unimportant radius on the ends was formed by a series of angular cuts and finishing by file.
The ends have bores set eccentrically so first off was to machine a fixture plate the same as that used for doing the eccentrics. The slot on the left side is only a few mm deep to receive a locating peg screwed into the end cap
Offset the required 2.4mm the bores were turned to depth and size less .5mm. The front register is for an insert to be JB Welded into place later.
Ready to 'weld' up
With the insert JBW'd into place the parts were set back up for facing and finish turning the bores to size and depth as well as drilling and tapping of the 8BA bolt holes.
The caps were held in place with the original screws and two new tapped holes put in which will eventually hold the feet in place. Held by screws in these holes the original screw holes were machined away as the transfer passage from the end cavity to the sump was milled in.
And finally the parts as of this morning.
The lower face of the sump has been milled at an angle to allow any condensate/oil that may collect to drain into the outlet.
Next up are the feet and the inner bronze bore - more on that as and when
Willy - if you are reading this have decided not to make the journey on Saturday - still don't feel up to it. Have a good day yourself though
That's it for now then -
Have some good modelling this year - I'm certainly intending too
From tha ol shid - 'Ole Tug'
Oh yes, perhaps I should add ... Having mastered the new skill of removing the lens cap (see Zee's thread on cameras
) all but the first two pics were taken on the new camera - a real little gem despite it's initial 'difficulty'
