A one off frame and fork build
« on: August 03, 2013, 09:25 PM »
Right guys. I have been thinking about this for a good while now and I think I will be going ahead with it so all your help and assistance will be vital  :coolsmiley:

I will be looking to build a freestyle frame and fork. What I would like you do for this part is list your favourite features from the old school freestyle frames and fork for some of them to be used on this. i.e I like the fork standers on the Trickstar fork, down low and thick tubing.

I would like you to keep things simple and please don't go off track and fill the thread with needless posts but please add pics too  :daumenhoch:

Firstly, it will be made from 4130 cro-moly with a NS geometry. What are your opinions on Braised or Tig welding? Which is the best and most economical to get done?

Sound like just my thing Terry. Who have you found to do it? I looked into it a while ago and while there are a fair few people who will make you a frame it always came in between 550 - 650 for a freestyler so i could never really justify the risk that my designs would ride well  :'(

Was my sort of thinking at the time  :daumenhoch:











The one continuous tube either side was the stumbling block but i did find a few places willing to take it on  :daumenhoch:

I think if you are getting a fabricactor to do it and is 'new school' he might not be able to use OA and do fillet brazing.
A braised frame looks the dogs but having said that if you get someone that's the dogs on a tig the welds look stunning.
Brazing may cost more as there's a bit more time involved.

MID is a definite progression on the US BB that's what I'd use.

I'd also be thinking about disc brakes, not kidding either   :LolLolLolLol:

I remember that Clint  :daumenhoch:

I was chatting to one of the engineers at work today about welding etc etc and one thing led to another with hinself basically saying to me he knows a good few skilled guys in the trade and sure that I could get something knocked up  :daumenhoch:

He is going to have a chat with a friend of his for me so we shall see Clinty baby  :)  As for geometry mate, I will just take a NS frame set and use that. It's just a matter of finding something that is suitable to my height. I would definately like twin top or bottom tubes and maybe something different with the rear setup.

I think I can get either braised or Tig, it's just a matter of what is stronger and better longevity.

Disc brakes are a no go bro unluss I can get them to run round the centre of the hubs   ;D  I just couldn't imagine trying an endo to peg foot plant and slicing my shin down the disc to be honest  :D  Besides, Kappy has already done that.

I will be going back to a good old fashioned 990 on the rear somewhere and have a think about something to put on the front.

You could do with having a few rides on other members new school stuff at a lock in or summat Terry and see what suits you  :daumenhoch: I have ridden quite a few recently and the only one i clicked with straight away way our kids subrossa ddt.
I literally got on it rode up a ramp and dropped in like i had been riding it for years and trust me that aint like me, i like a good half hour or so getting the feel for something before i get the bottle to do owt  :daumenhoch:

That may be a good starting point to be honest mate. I want to put a few old school touches to it though like Hutch fork standers, Curtis rear frame standers, 990 rear mounts with cables running internally. Stuff like that mate so, I thought I would ask everyone to get some pics up of their favourite parts.

I really like the Curtis rear stands -

Hope your feeling flush Terry the problem with having a custom frame is the temptation to have custom parts too  :-X

The problem is with the Curtis rear hoops is that your heals keep catching them as you ride which is not good at all. I had a Curtis freestyler but couldn't bloody ride the thing.

Great info mate, thanks. This is the stuff I am after, experience and first hand issues. I can maybe re-think the position of them and the length of the rear stays too with this info  :)

Don't worry about forks bro, I have those Gregg Melms custom made 1-1/8" forks like Bottemas  :coolsmiley:

Go euro bb, steep head tube, long front and shlammed back end. Not too high on the bb and make it look old school.

Oh. That would be my Retro goose :LolLolLolLol:

Terry, just remembered i thought about getting a mock up made from copper pipe just to get a feel for things. Its relatively cheap, easily sourced, bent and soldered.
I know from experience you can design stuff on a computer till the cows come home but there is no substituting having it there in the flesh and i think the extra cost would be worth it for the piece of mind of knowing you are getting exactly what you want. Its also handy for checking clearances etc.:daumenhoch:

I had a lovely looking design for my new brake system but when i got a prototype body laser cut out of plastic i found it was catching the crank arms slightly. Reducing it enough to be sure it would clear any crank used meant a partial rejig of the internal mechanism  ::)
