    I have read through days of posts about cycle fenders and it appears the use of round bracket material seems to be the least prone to cracking and breaking. My question is what is stronger.....solid round steel or DOM steel tubing? And should the tubing be cut and welded at the bends to strengthen them? Im copying the style shown here....or trying to. 06122013e.jpg

    Solid would be stronger. If tubing, yes for sure weld the ends shut.

    Having broken mine a few times, I encourage you to build them stronger than you think. Why? These fenders feel every bump along the way. Unlike "regular" fenders mounted to a chassis, these move with every move of the front wheels and feel every jolt along the way. The picture below was the first edition:
    IMG_0928.JPG

    Needless to say, they broke on me a few times.

    The photo below shows the third or present version. Note the gussets and addition of the circular brace (like your example).
    Something you can't see is the steel under the fender that the supports are welded to. Yes, this connection broke once too on me. My suggestion in your build would be to mount the braces on the fender end to something more substantial than the fender itself.

    Once more--it's tough out there for these fenders. IMHO the right side has it worse.

    AVater your post was one I studied a lot. Did you use solid or DOM tubing? I was thinking 5/8" diameter and fabbing some internal brackets inside the fenders to attach them to.

    I hope this thread goes for 10 pages. So much to learn, not much ever published on the topic.

    5/8ths DOM works and offers 3/16" plate mount flanges (3), a place to weld both sides. Never had a failure. Make one continous tube bracket that begins at outer edge (inside) of lower rear of fender (4 or 8 o'clock) then stand off the tire sidewall as you bend it. Weld to rear lower plate. Pickup the rear hole, then forward and Up, around lower front hole, capture top hole plate, then standoff tire sidewall, pass over top of tread (clear it), fasten fender to the tread tube-extended portions.

    4130 aircraft tubing, if you have to weld do it with a tig. Flatten area that mounts to fender and backing plate. Make a template first out of mild steel. I would bolt it to fender and baking plate. 5/8ths outside diameter. Then have it chromed. :)

    It seems like solid rod would be stronger but actually tubing seems to be able to withstand the vibration better. As others have already mentioned, flatten the end of the tubing in a vise or press instead of trying to weld an end on, a welded end will never stay.

    I read about using old rifle barrels, finding a matching pair may be a problem. Bob

    If you look to drivers side, along the front axle, from the ctr spring perch. The Ford spindle bolt holes you want to use, are at 8, 4 and 2 o'clock. Rear of fender mounts off the horizontal tube from 8 o'clock.
    The top of fender mounts from the ~ vertical end of tube, which passes by the 2 o'clock bolt/flange. Wish I had a detail pic, car was sold 6 years ago.

    Stainless steel , still vibrate but I doubt they will break bracket.jpeg

    Following along as I've had this same question myself. I've looked at nearly ever car with cycle fenders at hot rod shows that I could find and none of them seemed to do it exactly the same. These photos and explanations are great!

    Keep 'em coming!

    I like bobbed rear fenders and cycle type front fenders.

    But I know the cycle type fenders can be a problem. And the main problem seems to be that the brackets are only on one side. It would change the clean look, but I wonder if anybody has maybe attached outboard brackets to the spindle. Is that feasible?

    I never had any luck with these brackets or with welding side pipes.

    I used solid rod. Looks to be 7/16” but with paint etc could be 3/8”. Frankly the rod was something I had in the garage. If I did it again, would use thicker or perhaps DOM as suggested. Here’s another thought: old Ford bumper jack handles are 1/2” may be hardened?

    Ever seen a race car chassis built out of solid rod? Tubing is always stronger if you are comparing apples to apples.

  18. I used bicycle forks on the basis that they can support a 200lb man over rough ground they can support my mudguards.

    Bolted at four points and gusseted. Rubber between the support and the guard to reduce vibration.

    Somebody apparently did it with my old speedster, back in the day. Here are the cycle fenders that came with it, front (left) and rear. Outer supports connect to a spindle nut.
    IMG_3056.JPG

    Thing is, the castle nut spins freely inside the support, but there's no provision for a bearing. So apparently it just rode metal-on-metal? Seems crazy. Perhaps they were bolted on for show and removed for extended driving?

    IMG_3057.jpg

    Anyway, not sure this helps the converstation. I'm just saying, it's been done.

    Now this is interesting. And maybe to take it further down the bicycle parts path, maybe a proper silver bronze braze joint for any fabricated joints. After all steel tube bicycles are brazed and they take tremendous loads and beatings when ridden.

    Like that idea a lot, I can see in & out brake cooling louvers punched in that. Bob

    What gage is the support steel? This looks really strong.

    Back about 1990 , after running fenderless for about 10 years ; I was thinking of building a pair from a ‘36 tire cover. In talking about them with big Pete at Carlisle , he said he had just the thing for me. He said this pair ran on a Lehigh valley’32 thru the ‘50’s and ‘60’s and had never cracked. I have run them for about 30 years, still no problems…never did get around to painting them . Edit:they are made from tubing : AF53A386-339E-4655-8C3D-9109C14B250B.jpeg EF4688AA-2B4F-4AE6-9746-6ECFF6AD2C1E.jpeg 8F0D2FEE-60B4-45C0-8F32-BF4B1A2525E8.jpeg

    I must be a whimp as I used much heavier material and had most of it laser cut out as to minimise bends.
    Sorry that pic's are not really taken to focus acurately on the brackets but I figure you will get the idea after you stop laughing.
    I just did not want to be dropping a fender on the highway or worse...

    Old school sporty car. The mounts are not so pretty, but the fenders don't add any weight to the suspension. Sorry I don't know the make or year of this cool little racer. Could be a special, just don't know. The fender style reminds me of an Allard or Kurtis from the 1950s.

    A car from down under, or England possibly? Pix from FB. I had an idea to mount rears for my truck like these on the axle ends, but never got around to them.

    I built a pair out of a spare tire ring I bought for $20! Welded nuts to the backing plate and made steel rod mounts to bolt them on. I also welded flat steel strap inside the fenders for the rod to weld to instead of just the thin sheet metal of the ring. Haven't run it a whole lot but did notice they do flop around some so am going to add some extra supports to them shortly.

    In no particular order of fabrication. Used Ford steering shaft for tubing and 16 ga steel sides
