chassis costs

Postby Paul » Sun Nov 30, 2008 11:54 pm

I'm in the process of getting an estimate to have a chassis welded. Short of going and researching prices on tubing, axles, etc separately, does anyone have recent ballpark figures I could compare with when I get my estimate? I'm planning on a 5 X 10 with a Dexter torsion axle. I found some older threads with ballpark figures, but they were from 2005. I'm assuming materials have gone up since then. Any thoughts?

Paul,

A year ago a local welding shop made a 5' x 10' frame for me for $500 in labor and materials. They supplied all the steel, the coupler and chains. I previously purchased the Dexter axle... and should have had it shipped directly to the welder.

The main part of the frame was made from 2" x 2" x 1/8" square tubing with mitered corners. There are four cross pieces made of 2" x 2" x 1/8" L angle. The 48" long A-frame tongue was made from 2" x 3" x 1/ 8" rectangular tubing with the 3" side up. Each of the four corners has a gusset. They also welded on the axle support brackets, chain rings, mounts for two rear levelers and a front tongue jack, and mid front and mid back flanges for bolting the floor to the trailer.

Since then steel went up. I read recently that it's coming down. HTH and good luck to you.

I recently priced out steel from a retail outlet for a trailer similar in size as Steve's, but with 2" x 2" x 3/16" for the a-frame. The steel alone was around $220. I paid about $190 for my Dexter axle. I was planning on cutting the steel myself - chop saw rental $50. Not far from me is a small welding shop. The guy said he could weld it for about $250-$300. So add in the coupler, safety chains, and two stabilizers - ~$110 - and the total comes to: $820-870.

If you want to increase the strength of an A-frame, you are much better off to increase the depth of the tube, rather than its thickness - 3" x 2" x 1/8" tube is about 15% cheaper than 2" x 2" x 3/16", but it's 40% stronger and 12% lighter.

Thanks. I may do that if I have the clearance. Right now, my sketches have the a-frame below the frame rail. The axle I ordered is a 10-degree up Dexter. With the standard bracket, the unloaded height of the stub axle would be about 1/2" above the bottom of the frame rail.

Thanks for the info. I appreciate it very much. I've been lurking on the board for years, but unfortunately it takes me forever to get started on projects. I've had my hatch hinge sitting in the closet for a year or so. I had a friend of mine order it from Grant for me and didn't tell my wife until after it had been sitting in the closet for a while. 8) I've already got several sheets of plywood to get started with, but didn't want to start anything until I have a chassis.
