ALUMINIUM FRET LEVELLING BEAM - 12", 16" & 19"

ARRIVING SOON - Available to pre-order.
 
MATERIAL: Milled Structural Engineering Aluminium 50mm x 25mm x 3mm Wall Thickness.
 
3-OPTIONS ARE AVAILABLE:
12" LEVELLING BEAM - Multi-purpose tool for fretboard or body sanding in addition to fret levelling. Machined on all faces enabling 4 different grits to be utilised on the same tool.
 
16" LEVELLING BEAM - Machined on opposing narrow sides allowing the tool to be fitted with 2-different abrasive grits. Incorporates large chamfered hang hole for convenient storage.
 
19" LEVELLING BEAM - Longer length beam machined on one narrow face. Optimal length to span the full fretboard on most standard guitars. Incorporates large chamfered hang hole. 
 
IN-HOUSE PRECISION FINISHING PROCESS - SKIM MILLING
To remove the variances from the extrusions' milled aluminium surface, the levelling surfaces are skim milled - a precision machining process used to resurface metal parts - most commonly automotive cylinder heads. The metal removal depth is minimal - typically 0.05mm (0.002”). 
 
NOTE
Skim milling differs from the generic milled aluminium description - which refers to the raw material condition, having been processed through a series of dies(mills). 
 
Skim milling is a precision machining operation utilising specialised tooling & coolant which produces superior flatness and surface finish that eliminates hand linishing.
 
GENERAL
Non levelling faces are orbital ground producing a natural matte finish. Ends are chamfered to prevent digging in. Top corners are rounded for comfortable use.
