Hi, thank you for your advice. This is the 10" Ryobi drill press. Is this the one you had? If this is the case I will consider replacing. What brand and model do you recommend?mightysmurf8201 wrote:JuanPablo- If that is the same drill press as one that I have owned, which I'm 95% sure it is, your table is probably not sitting flush. You need to lift up on the table as you tighten the clamp, or else you will get a slight incline, especially with the weight of that cross slide vise on the table. Based on my many years of using that model, I'd like to save you a lot of headaches and suggest you return it, save up another $100, and get a halfway decent press, or another $200 and get a really good one. This model is not made for precision work.

Re: Drilling alignment problem
That is the same one. I currently don't own one. I sold the one I had when I got my lathe. Maybe someone else can recommend a good model?

Re: Drilling alignment problem
My dad own a lathe I can use but I have a hard time trying to center blocks and stems. It has a 3 jaw chuck. I've seen a special chuck for stems but can't find it because I don't know the name.mightysmurf8201 wrote:That is the same one. I currently don't own one. I sold the one I had when I got my lathe.

Re: Drilling alignment problem
Like a lot of pipemaking tools, that "special chuck" have to be fabricated and can't be had from a shelf.
Regarding the drillpress: I also had a little Ryobi way back. It worked sort of, but was a piece of crap. There is play in the table, even when tightened down properly. It doesn't stay level, especially under pressure.

Re: Drilling alignment problem
The table sagging under weight of the vise makes more sense than any other theory in this thread.

Re: Drilling alignment problem
Althoug the drill might not be a high quality and precision machine, I take most of the blame here. Instead of trying to level the block on the vise, I tried lining the edge of the vise grip with the lines I draw around the block. It seems that I was twisting the block enough to drill the air hole at an slight angle. I've drill 6 blocks using the new method and it has worked for me. Thank you all for your help.
