I know this might seem like a silly question to ask most bowl turners,,but I have been making a few bowls about 5 inches wide and actually I feel much better about the hollowing out and I have gotten me a few bowl gouges,,a 3/8..1/4,,and a 1/2 inch,,,and have been using captain eddies setup on sharpening them,,the 7/4/2 method,,but I find the deeper I get into the bowl it gets harder to ride the bevel or have control over the gouge,,it seems like I can not get enough angle to ride the bevel due to the handle hitting the lathe bed,,do I need shorter gouges or am I doing something wrong,,i actually would like to go as deep as I could,,but as I said,,the deeper I go the less angle that I can ride the bevel due to the handle hitting the bed,,any comments would be appreciated,,thank you

A lot will have to do with the style bowl, it may be like a wok or more like a dog food dish.
For a steep radius in the bottom there are three methods that I know of.
First is to switch to a smaller gouge for finishing. You may rough and do most with the 1/2 and make the finish cuts with the 3/8.
Second is a steeper grind so instead of a 50-55 bevel you have a 65-70 bevel (bottom feeder).
Third is to grind a secondary bevel as shown in this gouge by Hamlet.

Any of the three methods or a combination may work and help you keep bevel contact by making the bevel shorter.

I thought others will more experience would jump in.
I am not sure why you are hitting the bed.
I found these two videos that show approximate angles to the rest.
Generally you start the cut then follow the bevel through an arch ending almost parallel and at center.
In the Lyle Jamieson you can skip to about 5:45. Lyle does have other videos on youtube.
