teamferret Posted August 4, 2010 Report Share Posted August 4, 2010 As lons as you gear it low enough the WD gearbox is not necessary and tends to allow the use of 1st only due to the gap between that and 2nd. We always used B44 barrels shortened to suit and turned round on a lathe mainly for cosmetic purposes Ian Teamferret Quote Link to comment Share on other sites More sharing options...
