I've been wanting to make a cable holder for the bike, finally got round to doing it last night. I started with a cast block of aluminum that my Granddaughter helped me cast earlier this year.
So here's the pictures.
marked out sort of what I want.
this is the other side I milled it flat.
I cut the block in half the drilled and taped it for a 1/4-20 SHCS to hold it together while machining. The same bolt will hold it together on the frame
here it's getting bored to fit the frame of the bike.
bored for the frame and drilled to fit the cable

marked out material to be cut away either by milling or sawing, I did both.
All done I sanded and filed it so it didn't look too rough, polished some as well, cast aluminum is a pain to make real pretty so I stop polishing when it looks good enough for me.
here it is on the bike, this replaced the plastic cable tie that most bikes have to hold cables and wiring in place.
I could have bought one but for me it's fun to make my own. I checked I could have bought one for $10.00, but none have any o-rings inside the clamp to protect the frame from scratches. The big plus, my Granddaughter helped make the cast aluminum block I used to make this clamp, that is priceless!!!
Now to go ride the bike some.

Looks neat.
How's it fitted? Is it split?

Looks great, now to you just need to anodise it so that it doesn't corrode.
It is nice that you are getting the grandkids interested in machining. :)

Yes it is split, I have split o-rings set in machined grooves on the inside to keep the aluminum from scratching the frame.
I've heard that cast aluminum does not take anodizing very well. So its going to stay bare for now.

Good idea with the O-rings.
Aluminium takes anodising fantastically, although it does depend on the grade of aluminium used.

I've anodised a few cast parts, but results vary enormously. Anything die cast seems best, but rougher cast pieces seem to gas off a lot in the acid bath and they don't seem to coat too well, usually the result with these latter types is a reduced depth of colour after dying. This can only be down to the properties of the material used. Having said that, I get mixed results with extrusions and other forms of Ally too. I guess a test would be to cast some melted down T6 and see what prevails, as that's what I get the best results with normally.

I'm going to try hot bluing on some metal once I get all the chemicals rounded up all I lack is the lye to do it.
I might have to give the anodizing a try I have the electrical stuff covered.
I don't have the chemicals to anodize, but I could gather up the stuff easily, I do like to experiment.
I need to break out the lab coat, respirator, rubber gloves, and goggles. Might need to get my Cat out in the shop to help! Ha! ha!ha! Here Rufus kitty, kitty, lets go play!
