Got a little polishing done and repurposed some old Axial bl rings.





Polished vs Satin finish. I like either, but once you polish one its hard to not do them all.

Sexy Sexy
damn fine job!

[JeremyH]

Nice work!

[CREEPERBOB]

Bad ass Chris , ain't it awesome .

[Szczerba]

Always making the cool parts no one but you can afford!

I kid, wait, really that's true. Awesome machine work and innovation as usual.

[Badd]

Nice looking wheels Chris .

It is. And now I'm sad that I don't have enough material for another set.

I'm gonna make more, but this time with delrin. They might actually be affordable.

nice! assume with the slim spokes you were after light weight?
what do they tip the scales at?

how much you want?

[Duuuuuuuude]

They are 4oz without rings or hardware. Heavier than I'd like, but I'd need a lathe to take some material out of the middle.


Oh, I could use another foot, maybe two for giggles...

[Etype R]

You could use a t slot cutter to remove some material.

[STANG KILLA SS]

crap I just measured it, its 1.9 bars.

True...it'd give me an excuse to get some...

Want to sell me a foot of it?

Be careful with straight flute t-slot cutters... they tend to chatter a LOT but staggered tooth is better... that said I have done it on a CNC before once I got the Z set right it was no big deal

They will still take about as long and Delrin is usually about double the price of aluminum, even 7075.

I can move a little faster and confidently through delrin than I can aluminum.

Got on ebay last night and ordered a foot of 2.5" delrin for just a little bit more than I paid for the t6061.

So I've been scratching my head about making a better fixture for making wheels. I got by ok the last time around, but it was a little sketchy and all the clamps/bolts holding it all down would sometimes hit the quill if I wasn't paying attention.

I had all kind of ideas, then it occurred to me today that I still had a crummy little drill press vice. All it needed was a little work to tighten it up and some new jaws to hold round stuff.


The victim: a Bessey drill press vice. I had no illusions that it would be flat or true, so I bolted it down to the table and got it straightened out.



Once that was done I cut up some scrap aluminum and made a couple of jaws.



With 2.5" delrin wheel blank in place.




The only thing left to do before its trial run is to chop the handle down so that I can get full swing around the rotary table without it hitting the post.

Smart thinking man! If you are doing an op1 you know the outside material isn't super accurate anyways so long as you can get a good flat surface and the part looks good your set. How did you hold them on a rotary table to do the features?

[Duuuuuuuude]

I was holding them with clamps. I cut a 2.5" (+/-) circle in a flat steel plate that was clamped down and centered so I wouldn't have to indicate every time I flipped or changed pieces. Cutting the bead groove was the worst...I had less than a 1/16 to hang on to.

[Crawling Calvin]

Try picking up a 3-jaw chuck... those are handy for holding round stock its how I held my wheels when I was making them

[Calderwood]

Why are you using the drill press vise instead of your new shars?
