I also use Richard's holdfasts with "sub-optimal" holes I drilled using a hand brace and spur bit. I quite like the way I can tighten and loosen the grip by rotating them in wonky holes.JMcK":3q7a4452 said:I'll probably get shot down for this, but I looked at this problem myself several times (a woodworking hobbyist) in the end I used a hand-held drill with a 20mm wood drill. I made it as upright as I possibly could by eye and a square and then drilled the holes.
I felt, and so far have been happy with the result, that, provided the holes were as near as possible to vertical then any dogs used would be able to do their job. Obviously, I'm not talking about large erors
I also use Richard T' holdfasts without any problem. The fact that holdfasts work by exerting a sideways pressure on the hole means that any tiny error has no effect.
As I said, I will probably get shot down for the above.
Me too - I just have a couple of set-squares on the bench at 90 degrees to each other. I line one up by eye , the missus watches the other one and tells me when i go off vertical (or you could use a mirror).deserter":3fb6bnsx said:Also drilled all my holes with a cordless and spade bit, works a dream, just take it steady.
Hi, yes you are correct, spiral cutter was around £60-70 whereas I have found a drill press for about 13!marcros":3usyav68 said:you should be able to pick up something similar to that rig for peanuts on ebay. Cheaper than a spiral router bit.
