Nine times out of ten, when I see something really impressive, sure enough, it's from somewhere in Europe.

Man I loved seeing that cylinder with the risers still attached.brings back memories of my time spent in a gray iron permanent mold foundry that used to be here in town. As is aid before spent time in an aluminum foundry as well, but it was permenent mold as well. Only had one experience with sand casting aluminum and that was in school. In the picture of the "failed" attempt what caused the fins not to fill up? Were your vents to small or was the mold too cool?just curious because I may try this someday and you seem to have it together.not to many foundries over here where you can just walk up and ask them to cast something.awesome work and incredible tenacity to see this project through.

Thank you all for the comments!
Yes, too cold,- after I cast and failed the first cylinder, I upped the temp. 10 degree celsius and basically was´nt pussyfooting when pouring. Had the fantastic experience of seeing the alu when the pour was done, actually moving in the runner and in the feeder at the same time, in an ever so slightly swell up and down; and then I knew it was going to be a good day..

I have to say I am just so impressed with your ability to make castings on a small scale like that. In one of your pics there was some round foam. Is that what you used to core the cylinder bore in the casting? We used sand cores to make bores in cylinders.I had heard of styrofoam cores but had not ever used them.

Thank you.
They are just standard sand cores. I do use "lost foam" technique once in a while, but find the surface quality too poor.

-So in order to relax a bit and not do something serious about the X, I decided I needed a tail light. Milled the lens for it with a 2mm endmill in clear acrylic,- couldn´t find transparent red in the right thickness, but did a small test in thinner ruby acrylic on the laser. Had the good fortune of two days of glass introduction at the Royal Academy. Tried to cast it in glass with various success.. I´ll probably end up using the acrylic one! But it was great fun!

And of course the tail light housing. A bit of lathe work, a couple of holes and fitment of the lens and we´re good to go!

That bike is going to be a beautiful machine

I hope people appreciate what an art it is to be able to produce castings like you do. So many things can go wrong, especially in a sand core .cant wait to see what you do next. Subscribed.

Hi Gang.
Just a very short update. Seems like classic Autumn melancholia has crept into my project. Things just take forever. The Rain has started, not that it actually stopped during Summer.. So..Well..

Managed to cast the second cylinder, did have to try a couple of times. The minimal release draft of the fins kept playing up and some of the fins did´nt cast completely. I´ll just build that up with my TIG. Not to worry, it´s doable.

Meanwhile on Ebay, I followed this interesting auction,- you don´t see many of those around. Jeez,- wish I had the money..

Mads

[mads4]

Oh, forgot, Knuckleworks, your Tail light casting was done a month ago, I just never got to the post office.. I´ll pull myself together!

Looks great Mads!

I have a set of those heads and cylinders looking for a 101 Scout to put them on.
