Wizard.. I've been doing custom inlay work with carpeting for 30 years..which includes but not limited to, edge finishing.. speedbinders based off the 107 with single or double pullers.. even had a 107 mounted on wheels at one time ..multiple portable binders based off of full metal domestic machine with different bars to accept larger needles.. union special servers 81200 class..two and three thread versions. Basically use the speedbinders for 7/8 polybinding.. just looking for something different walking foot wise to put on 1 1/4 folder binding.. and doing blind stitching and wrapping.. this all done a 12'x24' air floation table..the portables come into play when doing onsite, or just to large for the airtable.. leather wise, put on wide leather wraps..leather binding.. and embroidery into the fabrics or leathers I use.. so actually a chainstitch would be nice for a free hand embroidery setup..give it a different look.. I guess any machine could be considered "high speed".. I prefer slow especially when dealing with a heavy Berber 10x10..250lbs floating.. doesn't take much to deflect the needle into the throat plate ..needleguard..hook.. all sorts of noises occur..lol.. onlyy time I might run a machine wide open is doing carpet base 6" wide usually thin.. have a union special strait stitcher for that..60' a minute...
