Hi Willy,

I had noticed those details in some of your earlier pictures, and wondered how on earth you would make those, or would you make something simpler.

That jig is a most ingenious solution to a quite difficult problem.

Wonderful progress.

Hi All ..the jig seemed to e a good idea at the time but i need to sort out how to actually use it as the finished part was a bit wonky ..However  on some of these engines the prototype parts were also a bit wonky....I may use brass again as i have found this silver solution that i thought could tone down the brass to give a sort of steely hue...still working on that...

Having another go at these strap inserts but still not happy with them.. Am thinking about using a slitting saw to get the right dimensions ... using it in the lathe...  however the diagonals will be quite thin  about .014" and might get distorted quite easily when cutting... will see what happens...I have a slitting saw attachment and some .015" brass shim so will try it out !!

Ok... I have been rethinking the straps and have modified the jig...Rather than cutting diagonal slots i have remodelled it and now just use the corners of the sliding parts to place the saw blade .I will be using the extra thin  .015" shim and using the very thin  Xacto mini saw This has seemed to worked on the first diagonal but, when i come to cut the other diagonal it may distort the first one ......we shall see what happens once they are silver soldered in place  !!The first diagonals were  .033" thick as i thought they would be easier to make !!

HI Chris, yes and one of the bits seem to have got smaller.......I thought I would be clever to saw the other web part without distorting the first ones. However after trying to fill up the gaps with soft solder to stiffen everything up when I filed the soft solder off , the part had disintegrated and seemed to have withered away !! I was using a flame source of heat and thought I was just filling the gaps with the solder!!  So I will have to make the part again and go back to the drawing board ??

Willy....it's the old story [in reverse]......"the hand is not quicker than the eye"......

So the gas flame is heating the iron first......the solder has not reached the molten state......then before you know it the solder has exceeded the fluid puddling state & ends up as splattered droplets & burning your trousers :lolb:

There is a Chap from Canada 'George G'...who posts on Model Mayhem.........he is a true Artisan :facepalm:  in soft soldering brass scratch built components for older model ships

Derek

PS...I once partially submerged a 3" iron bench vice in water in the kitchen sink as a heat sink :Lol: it worked perfectly.....I had soft soldered M3 tapped brass hex standoffs as feet, but each time I attempted to solder the additional vertical valve spool....the heat transfer affected the alignment of the feet.......so into the sink with water  :ThumbsUp:

Hi Derek, thanks for the post and yes it is a learning curve when we try to be jack of all trades but masters of some !!!!  I have had more ideas about this part and have come up with the following.... After the insertion of the first diagonal parts   .015". and silver soldering in place the small wedges were installed to keep these parts from distorting . this seems to have worked but I do need to make a new jig to enable greater depth of insertion also if the part is made from steel it would be much more stable.. when I came to clean it up the pressure of the file was too much for this small parts.... the photos...

Willy that is an interesting sequence for getting the final result. Like all things there are a variety of ways to get to the same destination.

I have to admire your perseverance with a right bugger of a part. I think if I absolutely had to make those I might start with a spark eroder.

Hi all , yes thanks, there are different ways to do stuff and a spark eroded would be the way to go...however ,I dont have one of those !!......yet.. or the skill to programme the drawings.... I will persevere with what I am doing  though as there is no rush...It is the Forncett exhibition and gathering this Sunday but rain is forecast all day... I will get lots of photos though.  Will see all the local M.I.M. colleages there

That's a neat solution to building a tricky part  :ThumbsUp:  :ThumbsUp: Still following along in the background  :wine1:

Hi Roger, yes..however I have met my friend that does laser cutting and just asked him about how thin/thick he could cut parts !! so quick as a flash he switched on the computer and drew out a sort of part to see what would happen and then cut out the parts in black perspex....!!  So this is what he came up with.. I have put some metal coloured paint on it and it sort of might do....we shall see. The Forncett exhibition was a bit 'moist' with torrential rain all day. So only one large scale model ventured out.. and only a few exhibitors inside... I will post some photos soon...

I am guessing that the second vice puts the height up to a better one for the filing plus the good one does not get beat up with any file marks.
