I am having a few made at the local shop here, so I asked them to quote me on making 50 of them. If there is enough demand, I will have them done, although shipping may be a little silly from here.

These will be the 3/4 axle style with the disc brake flange included. The flange will not be drilled.

Why not make them yourself? All you need is the flat bar and a left side BB cup. Cut the disc, grind it round, drill and file the center hole to 3/4", drill and tap the disc holes, (Or use nuts and bolts) file out the BB cup center hole from 11/16" to 3/4", then weld it to the disc. You could use the BB locknut as a spacer. If you don't mind filing hardened steel, you could use the freewheel side of a hub instead of the BB cup

Have you tried it yet? I had no problem welding a hardened crank arm, but I know the BB cup is super hard steel - the kind that will chip if you hit it with a hammer.

I wonder if it would hold up to the forces of pedalling and braking, which would be extreme, especially between the BB cup and axle where it is welded?

I might just have to test this out one day.

Now I'm going to have to try it. I was planning on doing it on the hauler when I make the 20" wheels, but that will now be a priority.

So brad are you having the schimano type hub adapters made the one where you can bolt the brake directly behind the hub as in the Kyoto plans.
And if i buy like 10 of them will ya drill and tap the holes for the brakes. LMAO

I was going to have the machine shop give me a price on 50 but they will also be tapping the holes for the brakes on mine.
I have a cheap drill that i dont feel like burning up. Also going to get a price on the hub adapters while im there.

Wont be having these made. Well back to 5/8" axle on my deltawolf.
Hope it holds up to my 350 pounds lol
We shall have to see I guess.

I am assuming that I would need only one of these for a DW build. To my surprise, you are doing this with 3/4 inch axels in mind, which is the route I was going to go. Do you have any pics that you could post to show us what they will look like?? How much would one cost me?? Shipping would be to postal code 60018 in the USA.

Any update on this? I would buy a couple that were machined, I tried to make a pair and they look cobled....

I will probably look more into this next year as I am building more and more trikes.

I'll take three, if the price is close to good.
Thanks.

Do you have the streetfighter or kyoto plans I think the plans are in there for the adapters.

If not shoot me an email I can send you a copy of the adapter schematics.

I have a lathe......... I have a milling machine.....I have time.........


I could prolly whack a few of those thingys out. Since I haven't gotten around to trying the trikes or quads yet I don't have the schematic for the adapter.
If somebody will send me a machinist drawing, not a scanned bar napkin cartoon. :1eye: think I can beat $73 each by a BUNCH. As long as they don't have to be made from unobtanium 236 or the like. I can help.

let moi know

:builder2:
I'm new to the site. I've been building recumbants, off and on, for over 30 years. I'm working on a tadpole tri-cycle with front wheel drive and rear wheel steering. I have read in some of the blogs people looking for freewheel adapters. I made several today for my project. The're 3/4" I.D. with 3/16" keyway and 2-1/4" set screws. I can make any configuration, for freewheels or discs. I'll get some pictures of my laydown and situp rides, and the adapters.
I am semi-retired and enjoy building things. If I can help anyone let me know.

Well this is one reason i have not built more deltawolves or the kyoto-cruiser yet, I hate doing this part.

One of these days I will find a machinist who can make these cheap.

I'm closing this thread for now since it's supposed to be for brief classified postings only and it's becoming a rather long discussion.
