Well the Willys is tucked up in its lockup but still been making bits that have forgot, was topping up with coolant and realised I had no catch can fitted

I know I could use a coke or beer tin like some people use but wanted something a little better, legally it has to hold a pint but I made it hold 1.5 pints.

Was going to make it in stainless but as I don't really weld much aluminium I thought it would be good practise

Had a look in my scrap ally bin and only thing suitable was a piece of 5" diameter x 1/4" wall tube, A bit big really so I decided to turn it down in the lathe to .050" wall thickness.








Once the turning was done I slit the tube down the side and used a piston ring compressor to pull it down to 3.5" diameter.










Next job was to make some end caps, I didn't want flat ends so I metal spun some .050" flat aluminium sheet in the lathe to make curved tops, this is done by spinning the lathe at its fastest speed and pressing against the aluminium with a piece of hardwood dipped in tallow, Its gets very hot through friction, crude but it works
Once made the caps were welded in place, wasn't worried about the weld as it was to be scurfed off and radiused. I had a bit of a problem welding the .050" as I really needed 1.6mm tig rods but all i had was 2.4mm rods, the 2.4 rods tend to cool the weld pool too much and also give a higher and not so neat bead.








Next I spun up some threaded bungs for the top inlet and the bottom drain, also 2 more for the sight tube, these were welded in place, welding getting better with practise










I thought I would give it a polish










After spending time polishing it I realised I didn't actually like it polished so scuffed it up and painted it satin black, looks better know !!!
I also welded on a mounting plate but forgot to take a pic
