Cheap steel SSCX build

After having this frame lying around for way too long I today decided to turn it into a bike. But on a budget for once! It's a repainted steel CX frameset for cantilevers and I have no idea what brand this is:

As you can see I also have a HED Belgium wheelset lying around. The rear is a dual sided track hub and front a disc hub, so I think I'll convert the rear into a fixed/disc hub with this:

And then convert the frameset to disc by (TIG)welding 2 of these on:

For braking I already have a set of Shimano Ultegra di2 levers and AVID BB5 callipers, for pedalling I have a Praxis Works Turn crankset. And I'm thinking of buying a set of Fairweather CX by CG tyres.

I am still undecided on the cockpit, thinking about using a ahead adapter since I have lots of ahead/31.8 bars and stems lying around..

Lastly I'll ask for your opinion on the drivetrain since I have no clue what a decent freewheel cog is. Any recommendations?

I'll update as much as possible, but since the calliper mounts need a month to ship the build won't be fast

White industries and halo clicksters are the forum faves for freewheels!

Move the downtube bottle cage down a bit more too :)

A White industries would double my budget :O

Dicta and Sturmy Archer have a wide range of freewheel sizes, and cheap, can be user serviced sort of....
I have a Shimano freewheel to, can't say it's worth the retail compared to the other 2.

Halo clickster is a forum fave.
White industries is spendy but fully rebuildable at cost which steers people back to the Halo.

Should get away with brazing a brake tab to the frame, i would consider a new disc brake ready fork as the frame and fork pre-date disc brakes so not designed to work with them, chat with someone who builds frames before commiting to alterations.

Don't worry, done this before :)

Thanks for the advice on the freewheel though!

Well, at least that wheel aint gonna get disc brake ejected :)

Home builder :) subbed.

On the freewheels, and open to correction.

The budget choices are just that, they can be opened up with a pin spanner (or big rock and allen key drift) and only have 2 pawls.
From memory the Shimano are slightly better materials but also 2 pawls, going up again in price to the Halo you get 6 or 4 pawls and doubling the price to WI you get a similar pick up unless you get the Trials freewheel which has faster pick up again.

The cheap ones benefit from a squirt of heavy oil into them. As unsealed bearings.

yeah that was the reason for the flipped disc mount, not sure what way I'm gonna mount it this time..

Started stripping my crankset today to get some beautiful grey Praxis Works cranks

Cranks cleaned up nice:

Started cleaning up the brake levers today:

Ended up putting them back together again:

Progress so far:

Next steps is to fabricate some brake mounts and wait for some brake wires and rivnuts to show up.

You got some long legs

haha! just didn't shorten the seatpost yet and didn't want to stick it that far in..

Lean the bike against the brick wall, fit a saddle so we can do a scoblebrick count for lol's :)

Good job on the cranks.

Euph

Many many scoble bricks

Turn cranks look great naked!

ooof this gonna be nice.

The old steel on this bike was a struggle for my trusty TIG, but still:

While waiting for some small parts to arrive I'm thinking about what to do with the paint!? The welded parts are pretty stripped, do I just spray them black or silver? Or do I go with a complete respray...

Depending on overall condition of frame....... if the rest is not too bad and keeping original decals.

I would be tempted to stick a wire brush on a power drill.
Take forks back to bare metal all over, either polish up and laquer or rattle can paint.
Would strip down maybe half the stays length and again, polish/laquer or rattle can, or strip all the stays length and rattle can paint them.

I agree with this

That's a great idea, I might just go that way

looks great but have you reinforced the fork?

You can't quite see in my picture, but the disc mount I made goes up the fork for about 2 inch from where it bend on your picture :)
