Hi All

I'm making my cycle wing stays at the moment and can't make up my mind how to attach the mud guards.

Bolting them on would make it easy to remove them for periodic re polishing,
but sticking them on would be neater as there would be no fixings showing.

So my question is, if I were to use a double sided tape, i.e. Silkaflex or whatever, what size bond area would I need?

I was thinking of welding a thin strip of stainless to the stays where the white area is in the pic, or maybe in front of the pipe as well.

I assume the bigger the area of tape the stronger the joint, but don't want to go OTT.

Many thanks

Paul i use pu sealers [ tiger sealer ] sikaflex ] tex flex ] etc at work and it dose not bond to stainless steel that good if you use it make sure you sand the s/steel to get a good grip

How about that magnetic rubber strip stuff It would be easy to remove the wings for polishing, but the wings wouldn't tear if something got caught...

Seriously though, I had a Westie with the wings PUd onto flat brackets (the standard ones about 3-4cm inch wide) and they were solid as a rock. On my current ST I did the same, but found that when I had to remove one wing to fix the bracket, I could easily pull it off, which defeats the point somewhat... anyway, for refixing I used dome headed bolts and nylocs.

Do a search on here, though, I think I remember seeing one thread where someone had glassed in a metal plate incorporating bolts facing downwards, and fixed those through the wing stay with nylocs on the underside. With your wings, could you do something like that? May be more secure than sticking, but give the removability you are after.

I put two generous bead of PU adhesive on my cycle wings on each of the two cycle wing stays and my wings have held on fine. The GRP would give way before the glue. I see no need for stainless steel fillets or anything.

pu sealers /glue are very good to bond aluminium to aluminium --aluminium to wood or fiber glass but not that good to stainless steel

Paul how about this; best of both worlds. Bond the mudguard to your angle bracket using Wurth or similar and screw the bracket to the wingstays. (I'm sure fixing to a curved surface will not trouble you!) I don't think I would want to trust double sided tape. I did something similar on the Special and it worked really well. Once bonded the panel adhesive will never let go.

The mud guards are made of aluminium and the pipe is 1/2" o/d stainless.

If I bolt them the strip of s/s could be much smaller, say 20mm wide.

If I use both tape and bolts then I could get away with smaller bolts too, maybe M4 ???

(must get round to cleaning up those edges)


Thanks for the replies so far chaps.

Could you weld some threaded bar to the underside of the wings?

then they could be removable and wouldn't have fixings showing?

Paul , I stuck mine on using Sikaflex . The way I did it was to drill the wing stay in a couple of places on each stay where I wanted to mount the wing. Using 4 strips of !"x1/8" strip steel with a 6mm stud welded to the underside , bolted them to the top of the stays I then gave the underside of the wings a good clean and coated them in adhesive. Placed wings in position and left to set. They have been on now for 3 years with no problems with the wings. The stays are a different story. Would it be possible to do it that way on yours?

I'd bolt them on with dome heads.

I thought about bonding my grp ones but decided bolting them makes replacement a lot easier, and I can see me needing to replace them at some point

I made a similar flat strip, then drilled and tapped it, so no nuts on the inside etc and easy to put them on/off

I've had a play, and come up with a sort of "P" clamp.

This could be drilled and bolted with tape between the guard and the clip.

perfect, absolutely perfect, lovely job!

ps how the bloody hell did you form that!

Er, sorry about the last post Nat.

Here's how.

Clamp & bend up 90.
Fold round 12mm bar.
(so that it's a tight fit on 1/2" pipe i.e. 12.7mm)
Clamp in vice and bend to form the "P".
Cut off

This may be of use to anyone who needs odd size clips.

Nice job, if you have spare time you could come visit :-)

LOL no worries Paul!

From your first piccy I thought the bracket was stainless, and that made me wonder how on earth you had formed that thickness of stainless into that shape!!

Looking at the other pics I assume its ally, which makes more sense now!

Yup, they are 1.6mm ally, but they could be made in s/s, in which case you would make them in 1mm.

The trick is to start off with a long strip so you can get some leverage to bend it round the 12mm bar.
