I had a sudden concern about how the 510/520 might affect my work. I do a lot of boxes with miter joints, and I find that a good way to make accurate miter joints is to rough cut them, then flip the table to 45 deg and use the disc sander to finish the joint. This method works great for getting tight fitting miter joints wiith a minimum of fuss. Now, with the table tilted at 45 deg the distance from the left edge of the table to the top of the disc is 3.5 inches. With the 510/520 table, which is wider, there will be less useful area of the sanding disc when the table is tilted to 45 deg. Is this going to be a problem or is there a fix for this?

Ed, you crack me up! :lol:

If you haven't already purchased a new laptop be sure to consider ACER. Best bang for the buck in my opinion and experience.

James, unless I'm missing something (which I do often enough) there will be no change in the setup you describe. While the 520 table is indeed wider and longer than 500 and the carriage is different, you'll be able to get the edge of the table every bit as close to the sanding disk as you are with your current setup. The carriage will be further away but that will make no difference in the distance to the top of the disk from the edge of the table unless I'm confusing the geometry. I'm picturing an imaginary 45-45-90 triangle with the hypotenus being your tilted table.

Well I have some good news and some not so bad news. First I think I understand how you are setting this up so let me start with how I see this.

On the 500 the table can not have a sanding disk mounted in the saw slot as it is 12" and the max that works is 10". But if you tilt the table with the low side away from the headstock and the sanding disk facing the top of the table you can sand away. If you were to use the 520 the larger table would hit the machine as you tipped it so you have to raise the table making the table taller then the sanding disk... so you can't do it that way.

Now the good news! The 520 can have the sanding disk mounted in the saw slot area. Now you can tilt the table and have lots of sanding disk exposed! The not so good news is that you will need a sanding disk insert if you don't already have one. The little bit of not so bad is that they are/were expensive (555116). If I recall I really needed one so I got it without it being on sale for like $26. I'll let you check the current prices.

Now I'm going to be gone for a few weeks again so I wish you well and if you have more questions about this get back to me with in the next very short time. I can set up and shoot a picture if need be.

Well I hope I didn't hurt your knee!

The wife and I went and picked up my new lap top today. I went with a HP (dv-6449us) that seemed to have all the features I wanted for a good enough price. I spent a good number of hours looking on-line and in the stores so at this point I'm happy. That is one part of my old job I miss, getting to be the first ones on the "block" with the new computers and hard disks, all that good stuff! I still remember getting our first new Philips CD-Recorder machine and burning CD at $26 ea. The first three came out as "coasters".... Oh well being retired has it good points too.

Acer is a good brand and when I use to work that is one brand I selected for our lab work. They were always out and being used and when I left every one of them was still working after about 2-1/2 years.

My old lap top is still kicking but at 166MHz the kicking is not too much fun anymore.

Actually, I'm concerned about the height. Say you do the following: raise the table to it's maximum height. Tilt to 45 deg. Lower the table to its lowest position (until the right side hits the tubes). Now, if the table is wider, you can't lower it as much.

By the way, I use an ACER laptop and it's not bad. Customer service aside.
