Introducon
The Academy Tools Low Cost Frame Fixture (LCFF) provides aordability, accuracy
and ease of use thanks to clever design.
Our proprietary User Calibratable Fixture Alignment System gives you the funconality
you need to check and control the alignment of your frame xture, independently at
every interface, every me.
This has opened up some really excing possibilies such as reduced
manufacturing and producon cost, at-pack design, reduced shipping footprint
and cost, user assembly & calibraon and a huge and expandable build range.
As a result the LCFF is the only fully funconal low cost frame building xture in
existence.
Laser Hazard
USE APROPRIATE EYE PROTECTION.
DO NOT LOOK INTO THE DIRECT OR REFLECTED BEAM.
NEVER POINT ANY LASER TOWARDS AIRCRAFT OR
VEHICLES; IT IS UNSAFE AND ILLEGAL.
THIS IS NOT A TOY.

Hollow Secon Beams
The LCFF is designed to use globally available mild steel hollow secon beams, of a
range of sizes, manufactured to BS EN 10219 or ASTM A500.
These beams are commonly referred to as Rectangular Hollow Secon (RHS) and
Square Hollow Secon (SHS).
Square - 38.1 mm (1.5”) to 40 mm
Rectangular - 100 mm to 101.6 (4”) x 50.8 (2”) to 60 mm
Wall Thickness - 3 mm (0.125”) (reccomended)
See the assembly manual for full details, including secon dimensions and lengths.
Mild steel hollow secon beams are inherently not straight. Each length of beam
will have a degree of bend and twist, within dened limits, this is a natural variaon
resulng from the beam manufacturing process. The Fixture Alignment System has
been designed to accommodate these variaons for the typical range of bicycle
frame sizes.
Setup & calibraon process summary
1. Set up the xture to the desired bike geometry (p 3-9)
2. Take care to correctly ghten the carriages (p 5)
3. Calibrate the laser pointer in the laser holder (p 11)
4. Calibrate the Seat Tube, Head Tube and Rear Axle features (p 12-17)
5. Install the correct bb spacer, head tube adaptor and dummy axle (p 18-19)
Important Calibraon Note
Due to the variaons in the beams it is necessary to calibrate the xture for
each frame geometry setup and every me a carriage is reposioned.
Calibraon of the laser pointer in the laser holder is an essenal rst step
before calibrang the xture.
