Adjustable Large Wheel (65mm Dia.) Double Roller Cutting Guide
Adjustable double roller cutting guide suitable for use with the Excalibur blowpipe range and ANME / PNME cutting nozzles which have a 15mm barrel diameter. Noz-Alls traditional ANM-6 cutting nozzles have a larger barrel diameter (15.5mm) and will not fit to the nozzle clamp.
Using the double roller guide can improve cutting accuracy for the artisan who uses gas equipment infrequently or for the experienced artisan where extended cutting torches are being used and it is more difficult to maintain the correct working height due to the nature of the work being awkward or out of position.
The double roller guide maintains a constant nozzle (pre-heat cone) height above the work piece thereby preventing top edge melt / damage caused by cutting too close to the work piece.
This large wheel double roller guide the nozzle is able to be adjusted in many ways making it very adabptable which means it will be suitable for most normal plate cutting, bevel cutting, cutting uneven heights et cetera. The double roller cutting guide has large 65mm diameter steel wheels which very easily ride over rough or pitted plate without being snagged.
Using the double roller guide has the benefit of ensuring the nozzle pre-heat cones are maintained at a constant 1,6mm above the plate surface for the most efficient cutting and of course helps to avoid the possibility of accidental touch downs which can induce backfire or sustained backfire.
The nozzle is clamped in a solid brass clamp fixed in position with 10mm hexagon head set screw.
The clamp may be swivelled to the left and right to allow for bevel cutting from only a degree through to 45 degrees. Clamp position is fixed using a wing nut. The double roller track width may be adjusted from being 93mm wide to 153mm wide.
overall width including the wheel fixing nuts on the axels is 165mm.
The wheel height is adjustable through 19mm on both sides. 16mm & 17mm AF spanners are required to lock the wheel height position.
