i used the plans from the shotgun website, with excellent results. I am definetly not a handy person either! I didnt bother with the cabinet - that seemed excessive.
I changed the dimensions slightly to make my life easier and save some $$. in fact the most expensive thing I had to buy was a new cordless drill driver!
My needs were a 60 inch wide table and I made it 30 inches deep so I would have some more storage room than the plan allows for.
I bought a 4 x 8 sheet of MDF for the top - had Home Depot cut it for me into a 60x30 piece and a 60x18 for the bottom shelf
Two eight foot 1x6 served to make the top box cut into 60 and 30 inch lengths.
For The legs I used doubled up 2x4s. I didnt want to have pressure treated in the house. Plus you can cut the 2x4s easier than a 4x4. If you can find untreated 4x4s and have the lumberyard cut them to size for you I would go for that.
For me the perfect table height was 36inches, so the legs were cut to 351/4 inches. I drilled holes and used lag bolts to hold the legs to the 1x6 box.
If you dont have a circular saw you can have home depot do all the cuts for you if you are nice - I found a fellow reloaded at mine and was he pumped up to help me out.
The bottom box I used 2x4s and set it about 2/3 down the legs for max support. Again, used Lag bolts to hold the 2x4s to the box.
Note the plans give the wrongs size recommendation for the bolts -I cant remember what size I would up buying but just do the math at the store and note that the bolts are only threaded for a little bit. be sure to buy washers so you dont eat into the wood as you tighten it down.
Make sure as you put it together that it is square and then with a helper screw the top onto the box.
Lastly - I put them bench on a rug which helped out with any uneveness in the legs (impossible to get them perfect) and it is rock solid. I am running a Dillon 550 and it does not move at all. I like the MDF because its smooth and wipes clean easily.
I would be happy to post a pic if someone could tell me how to do that here. Also - feel free to PM me and I would be glad to help.
