Hulsroy's Hustle

I think the potential of desktop cncs is huge, with proper work holding, apropriate feeds and speeds and sharp tools you can get a really long way. But it takes a lot of practice.

And time of which I don't have a lot...

I wish I had gone to trade school for machining, welding or carpentry instead of doing 2,5 years of photography before realizing the work environment was highly toxic. Would've accounted for a lot of craft practice.

Dad life and craft life are difficult to merge, when you have a day job as well.

Lunch time milling and test fit.

I am going to have to do this again. I learned loads tho

so much this: Dad life and craft life are difficult to merge, when you have a day job as well. ...
:-/
managed to get my steel frame before the arrival of my kid otherwise....zero time

It is been my project since 2012 to become an architect that is not an office slave. It is hard work 😃
Hopefully I can do more of my own work soon. Working on it at least.

Enough existentialism

It appears I have fixed the shitfting (get it?)

hahaha i am an office slave actually.... we make cool projects anyway ;) some of them! take a look if you fancy!

I try to make the best of it - and rolling around on the floor with a laughing kid is a pretty good time. I don't mind putting of some of my projects till she gets older.

Chucked the shifty bits to run it fixed instead @Hulsroy?

No not yet. actual gear shifting gas improved

Nice!
Is the next version going to be made from brass to keep the aesthetic?

Mmmm I might have some you know

I figured.. It bet it'd be real pretty too

Uhhh I am getting the speeds and feeds right it seems. Swapped for a two fluted fresh end mill as well.

After dinner tonight I headed back down to the workshop and finished machining the hanger adaptor.
The feeds and speeds where much better the third time around, but finish is still not great. But that's alright. It will pass as artisanal...

Had a minor issue with the ball nose doing the nice rounded ramp. I forgot to set the tool height so it went a bit deeper than I'd like and alternated the shape. But as it is only cosmetic I let it slide...

Works like a treat. Which is what really matters. Just waiting for Hope calipers to arrive and we are golden...

Love it.
Ps: Your tinkering is always great inspiration!

Thanks. Appreciate it.

Having had similar issues (wheel placement, clearance vs shifting etc...) I wonder if it would not have been simpler for you to braze a vertical dropout, but then the content of the thread would have much been poorer for it.
That CNC business: does it makes the part automatically from your CAD files, or is it manually operated?

Well. I was limited to a similar dropout to the one I originally used back when this frame was build. We were testing a Bear Components prototype that proved to not have enough travel. In 6 months non of this will have any importance as I'll go back to use this frame fixed or ss.

I program tool paths for the CNC using Fusion 360. This writes g-code that tells the machine feed speed, spindle speed and X Y Z movement.

ALSO first post of this thread clearly states the intention of it all:

There is no reason for this

There is no reason for this

Fair! That sort of tinkering is nice to watch, we're all enjoying the journey.

Thanks!

Great mod. If you have any video content, feel free to share it here 😉

Thanks. There isn't any really. When I do stuff like this I am too concerned/concentrated to film.

I'll see if I can do some brazing and TIG videos when I progress with Jens Arne's frame.
