I need to fret out some smallish shapes from a sheet of fibre glass based
printed circuit board, about 1.5 mm thick. Since this is a one off but
necessary exercise, I thought a cheapo Ferm scroll saw (in Screwfix cat.
£35.00) would do the job. Not perfect for the material, but feasible? Any
opinions?

Also, blades are sold with 10, 15 or 20 tpi. Which would be the most
appropriate for the job?

TIA

Probably. Aldi have some in at 30 quid just now (my Dad bought one
yesterday) and Axminster do their basic one for 35

For GRP, go fine and slow down if the cut starts to bung up with
sawdust. Expect the blades to wear out in no time when cutting GRP.
Try to control the dust too - GRP dust is nasty stuff.
