Fair point Dave, and effectively concurs with what Eddie and Ray are saying.
I recently spent the best part of an afternoon doing a drawing in MS Paint for a local engineering firm to cut and drill a top for my welding bench. Quite honestly, I could have done it in half an hour on a drawing board !
For 'one-off' jobs, the wonders of CNC etc probably aren't worth it….as I'm saving up for a decent lathe at present, the specialist machining saws may have to wait for Father Christmas.
Cheers for now,
Dave C
