Thanks Marg
Yes that is correct. Using my normal fret saw which has a reach of only 11 1/2 inches can be a BIG pain in the neck and for a long while I had to limit myself to smaller pieces. It stands to reason that when doing small portraits the details also get smaller so I had another 2 saws manufactured, one with an 18 inch reach and the other 32 inches, (but that one is so heavy I hardly ever use it because of the weight and also the reach of my own arm makes it very difficult to maneuver). Because of this drawback the biggest portrait that I have ever cut was about 24 by 17 inches and very detailed. I will post a pic of this soon.
Regarding the same problem I had also tried spiral blades but because of the slow speed of cutting by hand and not motorized the blades were ripping the wood rather than cutting so had to give that a miss. I normally use size 2 blades but when things get really intricate I scale it down to 0/2 blades.
Hope this puts things into a little perspective
