Default What vintage fork will fit a 3-inch tire?

I've had a bug in my head lately to build a leaf spring front fork. I'd prefer to start with a vintage bicycle fork but I think width might be an issue. My current tires are 2.75" and might some day have to go to 3".

Anyone know of a vintage style fork that will fit a tire that wide?

That's alright. I'll take a look at those. I intend to make the rockers, truss rods and springs myself but I don't really want to make the fork itself. I was hoping to start with a vintage 26" bike fork with the right look. Like this one:

I bought a fork on eBay from the guy listing this bike. He doesn't have any forks listed currently but he might have one stashed away. Not the highest quality like a Felt but if you're going to mod it maybe it will work for you. http://www.ebay.com/itm/1913-Harley-...m=131994645774

Thanks! That looks perfect. It didn't occur to me that guys are making and selling replica truss forks. I found a few old ebay listings but maybe someone is still turning them out.

I am making mine into a leaf spring fork. I've made some progress since posting these but it's the latest update in my thread just for reference: http://motorbicycling.com/showpost.p...&postcount=280

I linked to a couple of other fork builds and the eBay source for my spring as well.

This is a 3" wide tire fork is a Cuda from bicycle designer. I used only the fork part. Front are tierods from go carts and hemi joints. The fork comes with rockers that except disc caliper...but I had a very wide rim so mine are thick stainless thanks to Mr C Fox.Leaf is attached to bottom of fork. Had a threaded piece inserted in opening and welded in. Harold looking good!

That's a fascinating build you've got going on there Harold. I've been following. It would be great if I can find that fork. I'm using motorcycle tires and rims so I need about 3.5" at the upper part of the fork. It seems like vintage bike forks are out of the question. Waiting for an answer from the guy you bought from Harold. In a mean time I found another guy building them:

http://www.ubbcentral.com/store/item...116983270.html

I don't think they are quite as attractive (or authentic) in appearance without the tripple reinforced crown, but it looks like an option.

Motogaz, it looks like took apart a springer fork? I have a Monark fork but it's not wide enough and I wouldn't want to try to bend it.

I also played around trailer springs and have decided they are too thick. I may try some old snowmobile sprints as others have done. I'm really set on that curled under loop.
