Are you talking front or rear spider? Front is easy, bolt a Bald Eagle spider to a faceplate. http://bullets.com/products/Aluminum-Spider-Plate-5-Diameter/BE1125

They are very easy to make if you have a working lathe. I would look at these two recent postings as to design and ideas. Material wise, you can get 3/8" or 1/2" wall CRS or A513 tubing, or cheaper round solid bar 1018/1045 which would need to be bored. Unfortunately the tubing has a minimum purchase of 12". If you have a slip spider with set screw and someone makes it for you, you may want to have it made with a slightly smaller ID so you can finish bore it to an exact fit.

I think it would be helpful to others if you told us what lathe it is for, post a few photos, and general dimensions. Like spindle ID/OD, cover hole size, how you want it to attache (is your spindle threaded?), how long, and what you plan on using it for. The brass tip spider screws are easy to make, but I can send you a set of 3/8-24 1" Allen or 1.5" cap screw. I prefer to use the fine thread for the spider bolts.

I just have to ask? "I need a spider for my lathe. It would not be practical for me to build one at this time."??
If you need a spider I asume,(usually where I go wrong),that you have a lathe. If you do do you have a drill press as well?
I used a bit of hollow bar which is cheap and available at any steel merchant. As mksj has pointed out they are very easy to make.
Attached are a couple of photo's of mine. I put two rows of set crew locations in it as I often turn Hex bar therefore there is a band of 4 and a band of 3 holes, it just works for what I do. Sorry for the poor quality photo's but I just now walked out and took them and didn't clean up or rig lighting aye.
