New trike taking shape

Postby John Lewis » Sat Jun 07, 2008 5:52 pm

Here are some shots of the latest project. A trike for a friend.

I used the chainstay pattern from Bentech, The general layout from Tim Smith's site and the seat pattern from my logo.
I Intend to use 48 spoke BMX wheels to get the 14mm axle.

V-e-r-y tidy work John. Did you do the bends yourself?

cheers

G'day Harry,

Yes I did the bends. I have a cheap bender that does up to 19mm ok. It is imperial though and causes some problemss if not careful with metric sizes. I pack the tubes with sand for the bigger Diameters. For anything above 19mm eg. the chainstays I use the bender at a friend's factory.

I was given an ancient pipe bender the other day. Consists of two small wheels and a semicircular piece that is forced into the tube with a big screw. Perhaps it will bend muffler tube. I'll try when I get it cleaned up.

Yhanks to all for the comments. Looks ok in the pics but I can still improve the results.

Almost done

Well progress has been slower than I'd like but here's where we're at.

The trike taking shape in the background is a DeltaWolf from Atomic Zombie site.

Waiting on the chap I'm building it for to come good with the ready for the needed running gear. The rear wheel is from my LoGo. I'll be spoking this ones wheel when the spokes arrive.

Beautiful tike

Hi John,

Fantastic looking trike, I'm loving the colour you did, did you do much cleanup with the braizing? they look quite neat...well done.

Hi Storm,

Photo doesn't show the colours to advantage. It's a nice sparkling metalic blue Rattle can paint job, Anchor brand acrylic and clear acrylic automotive topcoat.

Look at earlier pics for brazing as you can see it only needs flux cleaning off. I used to have a lot of cleanup filing and grinding. These days I can do a nice fillet joint and hardly have to touch it.

My efforts with arc welding are still dreadful. I'm using arc on the new delta. Keep wishing I'd brazed. Still if I don't try I'll never learn.

That's the spirit John, keep getting back on that horse. I apologise for hijacking your thread but since we're speaking of the black art known as arc welding I recently finished off manufacturing the rear seat strut for my Lynxx. I used, of all things, light guage galvanised tubing about 16mm in dia with a 1mm wall. I don't know what I was thinking, thin wall is challenging enough without adding galvanising. Sheer determination was probably the only thing preventing me from putting the seat strut (and the welder) into a low orbit. The whole experience reinforced my earlier view point that arc welding can and will test your resolve regardless off experience. Here's a pic of the finished strut (still in earth's atmosphere)

Looks like it ended up Ok Harry. Thats a neat seat strut.

Is that a bacchetta seat? or maybe a Rans?

All this welding I'm doing is on 1.5mm mostly square tube at the moment.

I use a flap disk lightly to get rid of the galv. Sometimes I stick the end of the tube in spirits of salts for a while. Need to wash it well after though. Brazing doesn't like galv at all. At least with arc you can crank up the current a bit. Pity that doesn't work on thin wall tube.

Thanks John, yeah all said and done it'll do the job. The seat is a Bacchetta Recurve, by all accounts it is very similar to it's Rans counterpart and waaaaaay more comfortable than the original unit........IMHO.

cheers

Well at last I managed to find the time to finish this trike.

Came in at just on 20kg so I was pretty pleased. It rides really well and has a good turn of speed.

Shimano mid range components, Maxxis hookworm tyres. I kept the gearing deliberately low as it will be used for touring. 48, 38, 28 mtb rings to an 11, 32 cluster.

Well that's turned out beautifully John. Congratulations. So compact and clean.

My only question is: "How well do those brakes work?" That looks to be the weak point, especially if you're going to tour on it.

Cheers,
Graeme

John Lewis do you have a ruff estimate to the cost of this build on the completed project? I'm interested to see if the savings made warrants a look in for me too start a similar project or just buy one. Nice work BTW...

Thanks Graeme.

Yes, I'd have preferred disk brakes but was trying to keep the cost down.

The brakes seem surprisingly effective however and as long as they are kept adjusted and the pads in good condition there shouldn't be a problem.

Care is going to be needed on long descents though to avoid overheating the rims.

All the bike parts were bought over the counter at LBS and from Moruya Cycles and Greenspeed. With careful shopping and scrounging you could get the price down.

All new parts were used with the exception of the brake callipers that I had. I spoked the rear wheel myself. The fronts are BMX 48 spoke. The rear is 36 spoke double wall rim.

The all up cost was close to $700. I think I could do one with scrounged and recycled bits for half that or better.

Thanks John I might give ebay a shot as well to see how prices fair to build up the goods.

Looks great! How do you find the direct steering? Did you try different length steering arms to alter the ratio?

Hello Julian,

Good to see you turn up over here. Welcome to the forum. I've been following your builds on the trikes list.

To your question. The direct steering works fine and feels little different from the steering on my Logo trike.

I didn't try different ratios. It was just eyeballed to what looked about right. The bars would have been better longer but I had to fit them in the available space and still provide a bit of comfort.
