I've used a Shopsmith for a number of years but, woodworking is only a hobby for me. I have a Mark V 500 that's been upgraded to a 520. What model do you have?
The user group mentioned earlier is great. There are dozens of very knowledgable folks there.
I'd urge you to take the one day Shopsmith seminar when it comes to your area. It really helped me learn to set-up the tool so that everything is accurate. Go to
www.shopsmith.com , get on their mailing list and look for a seminar.
I know that once it's set up you should not have any problems.
If you have any immediate issues contact me directly and I'll try to help.
