Frame Building Course: Two Frames - Lugged and Fillet Brazed

Build your own
custom frame(s)!

In this 10 day frame building course you will:

* you’ll go home with two frames, one lugged and one fillet brazed

* you learn the two techniques for brazing frames

* you’ll learn about frame Geometry and design

* cut the tubes, file, and braze them together

* by building two frames, you will better digest and retain everything you have learned, as well a gain more experience by building different types of bikes

* if you’re interested in continuing to build frames after your experience at Big Forest Frameworks, this is your course!

Both. Brazed. Frames.

First we build the lugged brazed frame, which is the easier of the two.  Then a lugged fork that fits this frame.  With the experience of the lugged frame under your belt, you’re well prepared to build the more challenging fillet brazed frame, and it will be more fun.

I recommend to build a lugged road bike or single speed for your first frame, for rim brakes.   The second bike can be whichever type of frame you choose, including a mountain bike, with disc brakes.  This is a great way to enter the world of frame building!

It could be yours.

This is what you get.

1. Time & Place

The Deluxe Frame Building Course lasts 10 days.  The course takes place in my workshop in Potsdam-Babelsberg (only 30 minutes from Berlin via the S-Bahn).  Please send me a message to enquire about course dates.  There are a maximum of 3 students.

2. Possible Bikes

Most people first build a lugged single speed or road bike, and then a gravel, touring, or mountain bike.  If you prefer, you can also build two lugged frames, or two fillet brazed frames.

3. Schwierigkeitsgrad

For the first frame I show you how to build a frame with lugs.  The second more difficult fillet brazed frame we’ll build in the following week.

4. What you do

Everything.  Some frame building courses concentrate more on the theory.  In some courses tubes are already cut before you get there.  In my opinion cutting and brazing is the bread and butter of frame building.  In my courses, under my direction, you will build the frame completely by yourself.

5. What I do

I have all the tools you’ll need to build your frame, plus thousands of hours of experience building pretty much every kind of bike you can think of.  Working together, you can build your own frame that you will go home happy with.

6. Extras

Material costs are not included in the course fees.  The material cost can vary quite a bit from frame to frame.   The typical material cost for a fillet brazed frame is around 350 – 700 Euro.

Whether you’ve already built your first frame, or never had a drill in your hands before, with my tools and experience you can do it. And be happy with the results.


For the frames I recommend the best steel from Columbus and Reynolds.

Material Cost

The material cost from frame to frame can be very different. Typically this is around 1000 – 1400 Euro for one lugged and one fillet brazed frame, including a lugged fork.

    “Thanks for the awesome week!   The frame building course was awesome, I can’t think of a better way to spend my vacation.   The ‘work’ was really fun and I learned a ton.  I’m really happy with how the frame turned out, and super proud that I actually built it myself.   The geometry fits me perfectly and rides even better than I could have imagined!”

    “Thanks again for the awesome week!  The course was really fun and I am really proud of the frame I built.   I think you are a great teacher.   Always patient, you explained everything really well, and the ‘work’ of building the frame was never really like ‘work’ and I had a great time! :-)”

    “Sorry for bothering you with pictures from my bike. I tested it today for the first time and it was fantastic. I usually do not tend to be super-enthusiastic and there were of course some minor issues (like getting the position of the saddle right etc) but this was by far the most convincing test-ride ever. Super stable, yet agile, very direct. I loved every second with it.”

    Rather buy it instead of build it?

    No Problem!
