Hulsroy's Hustle

Really looking forward to seeing how this one turns out

Ta. I am thinking the actual build process will be quick and pain free, but all the prep will be sort of slow and careful.
Building for wireless and no mudguards or anything really is nice. You just focus on the lines and welds.

I am thinking about how to do the seat tube replacement on my cargo bike.
My current idea is to make a hole saw Arbor with a solid steel 27mm guide. This should allow me to drill out the seat tube free handed leaving the toptube and seat stay nicely mitered. Current seat tube is OD29mm but I am planning to replace with a 32mm tube that internally is 29.8mm allowing me to use this Zoom seatpost I've been saving.

Nice 👌

I know you want to keep hold of your 26.8 but if you ever fancy swapping it for a 31.6 lemme know!

My 26.8 is on my wife's bike I am afraid.

My girls were out of town last night so I went to the workshop straight after work with some frozen pizza and high ambitions.

Got all tubes in the front triangle fitted up. I am pretty happy with how it came out.
Today I'll do the bottle bosses and internal cable routing for the rear brake.

I'll see how far I get today but hoping to be able to do the flat mount and dropouts early next week and have the whole thing welded up in a couple of weeks working nights and parts of weekends only is not very efficient mind you.

Hey, if I remember correctly you had Bear horizontal dropouts on your SSCX but didn't like them in the end? Why was that? Because I'm thinking of getting some. Thanks!

If you don’t do a sweet skateboard grip tape job on this I’ll be upset.

Love the way you do top tubes to the seat tube like that

It was too short. Not enough travel for various chainring/cog combos. And the mechanism for tensioning was in the way for the single speed kit on the wheel.
And once painted the brass parts and stainless slider didn't fit the dropout. Might have been fixed now. Mine was the very first prototype dropouts

I will. Just not a priority now.

Been tinkering with my chain stay mitre fixture recently.

There is still some slotting and things I'd like to do but I am pretty happy with the cams

Do you do the mitring on a mill? How do you hold the fixture?

Yes. But I reckon it could be done in a pillar drill as well. I'll see if I can find a photo of the previous iteration.

I can't find a photo of it in action. But I made it as a specific wishbone mitre fixture and did chainstays on another fixture. Both held in similar fashion in a machine vice. But the extrusion fixture required me mitering the dropout joint first individually, which meant they were hard to get right. Now I can clamp the chainstays where I want them and do both dropouts and BB in one go.

That’s sweet. I want a small vertical mill like that so bad.
Need a dedicated workshop

You could look at getting a small lathe like mine. They can be sooo cheap and easily adaptable for mitering

That looks mega. Bet the wee one likes the trails.

It is really good thx. We did a little jaunt round the area and she cried when we had to go in for lunch not wanting the ride to finish.

I am just waiting for her to wake up from her nap so we can go for a proper spin

Bet the wee one likes the trails

Especially the gap jumps

Well turned out the little one had a fever after her nap so I wasn't allowed to take her out. We'll try again tomorrow.
I had a lovely ride on the rigid forks tho.

This is possibly even more good looking with the rigid fork
