Thank you guys. I am a little slow at making parts due to still learning as time goes by I will speed up a little especially where setting up goes

Well from my last post tomorrow came and went. I have spent time helping the wife get ready for Christmas as she is having problems with her back and unable to do a lot. On top of that a little shpping.
I did manage to get into the workshop and make a stand for a mobile phone charger see photo.

Then I did make a couple of support brackets for the valve rod assembly which are 0.600" long and to make life easier made a small jig to cut the angles on each end after refreshing my memory with a little trignometry. I don't think much will be done this side of Christmas but if any then I will post as and when there is any progress.

The jig with the parts still needing a little clean up then one with it in the vice showong how the parts will be sat in it and finally with it all secured and the angle being machined. I was appy how the jig performed. Just to point out the jig is a fraction narrower than the part so it grips it while machining

Three steps forward and one back seems to come to mind. I machined two little back plates which I made a simple jig as they are only 0.025" thick and 0.250 wide I did them both at the same time.

Then I desided to start on the fuel mixer the main body was completed out of a 0.500 hex stock  which went well. I then moved onto the little mixer bar that fits into the body drilled and threaded one end and drilled the small centre hole and this is where it went wrong O cut it over long and turned it around in the collet chuck so that I could machine to length being only 0.125" diameter and a 2-56 thread inside the obvious happened it snapped oh well I will machine to length first next time before drilling and tapping again.
The grub screw in the mixer need either a shorter one or the one I have needs machining shorter, thats for another day

No photos of the oops moment only the other work completed.

The fuel adjustment screw. Now where did I put it

Oh there it is

Next is the spray bar that the adjuster fits into I had to drill from both ends and a smaller one right through this is ny set up to get the correct drill depth one end is also threaded 2-56unc

the parts showing the main body, spray bar and adjuster with a tape for scale. The spray bar I need to set upon the mill to drill a cross hole with a number 76 drill (0.0197" or 0.50mm) I have left one end at 1/8" diameter until I get the fuel pipe from the fuel tank once I make that                         

The fuel mixer assembled except for the hole that needs drilling as well as a grub screw the right length

Been busy with other things since the last post. I have started to sort out the garden as well as look after the wife as she was not too good (all OK now) which meant housework and cooking which I love anyway(cooking that is)

Anyway had to remake the small fuel delivery bar as I was drilling it with a cross hole and messed it up as the bit was a #76 which is quite small. Now that is all done, I can make an elbow to go from the mixer to the head
Some photos of the fuel mixer with the bar which is only 1/8" diameter so that gives an idea of the cross hole size.

And the final picture of the complete fuel mixer

The last part of the fuel mixer assembly is the elbow. Not having one, I thought I would have a go at making one which will give me the chance to do some silver soldering.

I started with 1/2" brass bar and turned the ends and centre section as needed, with a piece of steel made a quick and simple mandrel which I loctited on and clamped at a 45deg angle in the mill vice and notched out before heating to cherry red and bending to form the angle. I thought this was easier than cutting it into two parts and trying to keep it lined up while I soldered it.

The photos should help explain my method of making this.
