BO15 Splinter (or how I learned to love a LOT of sanding)

[Machine Age Victim]

I'm finally going to build a bike I've always wanted to make. Been throwing around ideas for years and started collecting parts and materials since the end of last year.

The plan, pretty close to this design:

The material:

I've done some woodworking before, nothing on this scale, and 4 months is going to be a tight time-line.

Laminate monocoque frame or layered and "assembled'? Wood wheels too?

I'm really looking forward to seeing this come together. I love the design you came up with.

Layered and "assembled"! Yes, wooden spokes at least.

Here's the parts I have so far

Generator from hub for lights, roller brakes for stopping and a 7speed internal rear hub

Love it. Can't wait to see it come to life

Cool design idea!
RaT oN~!

That design has the vibe of an animal skeleton and rib cage. This is gonna be fun to watch.

I couldn't but notice the BB adapter...?

Yeah, figured that would be the easiest way to get a solid hold for the bottom bracket.

I need to find a donor "pipe" for the head tube that would fit a 1 1/8 steerer.

FWIW- a 1.5” x 0.083” gives an i.d of 33.88mm - perfect for an EC34 headset, after a bit of reaming. I’ve used them before. Aircraft spruce will cut and ship even small lengths of 4130. Only $6.60/ft + shipping.

Or, of course, cut & grind a cheap steel frame (c-list/ dumpster/ roadside). But $$ vs. time and effort is each person’s decision.

I have had a plywood and timber bike on my list for years, really looking forward to seeing this happen!

Any reason why this, in a 34mm ID wouldn't work?

I imagine that would work just fine. I can only weld steel, so I've only ever looked at steel. You may want to put a caliper on the headset bearing cup, where it inserts into the head tube, just to be sure it'll be a tight press-fit. I don't have any here that are not installed to check.

On the steel at 33.88mm, I do run a headset reamer to get the "proper" slope and exacting dimensions, but not much material has to be removed. (an expensive tool, but I was trying to build a lot more frames, once upon a time.) I suppose if the press fit is not tight, adhesive would work, but just make the headset cup a more permanent fixture than standard. Not the end of the world.

Extremely ambitious. Hopefully once finished it doesn’t lumber down the road.

Been thinking about a wooden bicycle off and on for awhile. Looking forward to seeing this one built.
