Thread: Drill Bit Selection

thanks for the tip david

i did notice also on your video that the blank vice you are using is putting a lot of pressure on the blank, judging by the look of the amount pressure required to close the jaws on the blank

you could also find with this type of clamp that you are putting tooo much pressure on the blanks which have just been reduced to 10 maybe 15% of their initial volume, loosing their strength/structure and being pushed out of shape by the external pressure from the clamp

when using a clamp on the drill press i have one that screws together and very little force is required to hold the blanks in place due to the V shaped groves on either jaw of the clamp

just my 2 cents worth, but worth considering

all the best

Well done, explains it well . You might have wanted to add, when you do have to redrill, make sure you use a good glue as there will be gaps.

I have had this occur on occasions. Now I have an old chain saw file in my kit and use that to just expand the hole enough for the tube to slide in with comfort.
Up to date to the best of my knowledge there have been no problems.
Just my two bobs worth

Nice one David!!!
