Hey gang, I've finally assembled all the pieces and gotten started. My previous projects have always stalled, so I'm hoping by posting my progress I'll stick with this one.

Another Great set of plans Brad...
Thanks !!

Update: The front boom and adjustable bottom bracket are complete. Moving to the seat next.

Question: What thickness of plywood and foam?
Thanks in advance!

Here is a shot of how I rigged up the bottom bracket to make final adjustments of the angle prior to tacking it together. I used the top of the top scrap tube is used as a reference to find the correct 56 degree angle.

Those welds look great. TIG, or O/A?

Looks like MIG from here.

They look too small to be MIG, also too clean on such thin material to be mig.

Its TIG.
In the second picture you can see the TIG torch on the work bench.

Good eye SSG. The TIG torch is on the bench.

Anyone have any suggestions on the thickness of the wood and pad used on the seat though?

Update: Made good progress with my time off for the holidays. Just need to finish the seat and steering and I'm ready for the small stuff. Finished mounting the seat support today.

I bought 3/4" plywood for the seat back. Still need recommendations for the foam... anyone?

Check out the cool reflective sidewalls: :sunny: http://webpages.charter.net/naumer1/Highroller%20Project%20009.JPG

Great welds!

As for foam:
I walked into a foam shop and asked for the firmest foam they had, the staff came back with this blue foam that was very firm. I got a 3 inch thick piece for the seat and 2 inch thick piece for the back rest. I toyed with the idea of using a 2 different densities for the seat with a higher density foam for the base such as expanded polypropolene (This foam is tough and bounces back into position but that would have meant a 5 inch thick seat so I just used the foam I bought. I also bought 3 foot of their black vinyl for covering.

I used two pieces of 3 layer ply for each seat first piece to staple onto, and the second to hide the staples and then I used SS screws in each corner to hold it all together. I also kept my seat, back rest and head rest as 3 separate pieces just to aid adjustabliity.

As a side note a grinder is really handy for shaping the foam just make sure to wear a mask. I didnt as I was in a ventilated area and suffered a very sore throat for days afterwards.

Hope this helps.

Nice welds.

I foam my foam and the marine grade vinyl to cover it in a fabric store. I bought some firm 1" scrap they had for really cheap and used three layers for the seat and two for the back. If I ever make another ply/foam seat I'll add another 1" to both. I didn't do any shaping to it and just covered it.

Thanks for the suggestions and comments! The visually appealing welds I leave alone. Everything else gets a dab from the grinder !!

Now I have some direction to go in for the padding... Glad I stayed with the 26" wheels, otherwise I would be able to touch the ground (I tried to fit my 700 wheels at one point).

I finished fitting the seat stay to form the rear triangle, today. The one off the donor bike is going to fit pretty well (looks like it was made for it). I'll post a pic once I get it welded in.

Thanks again to Lock and Dude !! :)

you can make a very high density foam for seats by laminating various layers together with spray on contact adhesive. Almost like building up plywood.
An electric carving knife is also good for neat cuts.
When making my m/cycle seats I used to sew the seat cover out of vinyl, place this over the laminated foam, compress the lot to the seat pan with large clamps and glue the overlap to the base.
When the clamps are removed the seat is very taut firm and neat.

Well, do to my lack of experience with covering the seat I was hoping to hit on a source for the same foam Brad used in this project and avoid it all together... :confused:

Brad covering a seat really isnt that bad you might check out a site like www.diynetwork.com for pointers on upholstering a chair which will give you the basics .

Hi Richie,
I forgot to mention to use a thick piece of plywood as the pressure plate to set the clamps on.
Heres one I did earlier, if you look very closely you can see the seam printing through between the 2 layers of foam.
I didnt leave enough foam on the rear upright part so its showing the imprint of the steel frame work.
I also use a section of polished ally sheet screwed to the seat pan with stainless self tappers to give a finished look.

Nice work. The piping adds a nice touch too.

Nice work. The piping adds a nice touch too.

Should have added this as well.
The piping is a 2" strip of black vinyl, a line drawn down the middle of the fabric side, sprayed with contact adhesive, thick cord layed down the line, then fold it over and clamp to glue tight to the cord.
Draw the seat pattern on the fabric side and cut out leaving a 2" margin.
I then tack the pieces together inside out with needle and thread and find an upholstery shop that will sew it for you with rot-proof thread. All the shops I've used charged very little and can do it easier than you can unless you have access to an industrial machine.
Once sewn the excess seams can be trimmed down.
I also use a thin layer of foam over the steel frame to add a bit more padding in case of impact.
I was going to button the seat above but decided not to in the end.
Its very comfy by the way.

Wow, I sure could have used that advice last week.
I did finish my seat but it took 3 tries and 2 knuckles.
I tried to use those upholstery tacks, they were worthless, couldnt penetrate the plywood.
I ended up buying 3/4"x 1/8" wood trim and painted it the same color as the seat back. Drilled and counter sunk the screws every 3".
Seems to look good, but I wont go that route again. Next time I will use the glue trick with diamond plate.
Thanks for your great suggestions,
Davo

Davo do you have an air compressor if so then next time your up in town stop by harbor freight and grab one of their brad nailer/staplers usually around $20.00 bucks and you can staple the snot out of the fabric :D.

I had set it up for red gum (very dense) and forgot to turn it down for the soft plywood.
In fact is was nigh on impossible to get this gun turned down low enough and still shoot staples:furious:

Update: Got the seat stay welded in today. This was tougher than I thought since the stay tubing is very thin... I melted through a couple of times. :mad: I had to stop to patch before I could proceed. :mad:

Plan to cut out the seat from plywood tomorrow and start on the handlebar.

Well its been a while :sleep1: fellow Krew members (1+ yr) but I've finally gotten back to my HighRoller project. Just back from the powder coater this week. Putting all the pieces back together, at least all the ones I can find !!

I can see the light :sunny: at the end of the tunnel so I'll finish it out shortly. This will be my first completed build and I want to get this one done so I can get going on the Tomahawk.

Oh - there's the seat in the back ground under the microfiche viewer... SWEEEET !

More photos to follow.
Thanks again for the support !!

I'll update these for the gallery this weekend. First ride was weak !! It was like starting over. Looking forward to trying it again this weekend.

Thanks for the help and comments !!
Looking forward to starting the Tomahawk.

Brad and Kat - you are THE BEST.
Thanks for your great designs and the forum to discuss them.

Finished at last. Looks great. Now get out and do some riding and tell us all how fast it is.
Nothing like riding on a bike you built yourself eh?

Well the first ride was last night and the second will be tonight in a few minutes. Last night was pretty funny. I was all over the road at first, but got a little better later. I'm hoping at some point it becomes second nature like the uprights...

Thanks for the comments !!

Once you really feel comfortable on it, it would be nice to have a ride / handling report with video... (I can dream!)

Excellent job -- looks highly professional. I get you will get a lot of "Where'd you buy that."

hello friends


I'm from Brazil and I am new to the forum.
I mounted my HighRoller SWB HighRacer using Brad assembly plans. It was good fitting because my conditions here are not good.
I need to give an updated and I have some doubts and I ask for your help, since its was very beautiful and well made.
The handlebars of her for being long he gets a certain movement like that is loose?
The handlebar inclination was good to make sharper turns?
Do you have a picture with you sitting on the bike for me to compare with mine, because I have 1.73 meters tall and weight 90 kg and for me is a little tight.
I'll try to put some pictures for you guys look at and express their views.

Welcome to the forum. I'm close to the same height (1.75m) and with the adjustable crank I still have about 10cm of adjustment left. I had to mock-up the bars several times to clear my knees while pedaling, but once done they should not be loose at all. Sharp turns on this design don't require much bar movement since the bar is so far away from the pivot point. Turn too much and you will crash. I find with this high wheel design it is very "twitchy" to ride. All steering inputs are small and gradual. I'll see if I can find a picture with me on it...
