    I used ratchet straps as well :thumb:

    For lowering the trans, as well as holding the knuckles in the strut towers during my clutch and suspension overhaul :thumb:

    BTW... the whole plywood vs lumber vs steel... who cares. It is ALL overkill. Im a builder and I work as a customer rep. at a lumber yard. I know lumber and I know plywood. Each have their own strengths (pun intended) and are used in a manner to take advantage of such strengths.

    If you are interested in quality lumber products, in terms of strength vs weight as well as ease of install, look into TJI's, LVL's, Micro-Lams, Glue-Lams, and other engineered lumber products. Always straight, always strong, and will never warp, twist or sag. All while being similarly priced in comparison to standard lumber, AND in most cases, weighing MUCH less.

    Did I mention it ALSO utilizes recycled lumber products ;)

    Okay... somebody did ask... :bonk:

    I noticed the front support has an 80 deg angle. Is there any reason for this?
    Also if i made the pipe holder does there nd to be any angle on it? :eek:

    Software (21 hours of a M.S. in Computer Science Engineering, but went back to work after a nice job offer instead of finishing)

    The angles of the eye bolts with respect to the beams is due to the changing angle of the fenders (and beam footers) as they drop toward the front of the car.

    P.S. I have been away from the SHO Forum for the last couple of months due to my long term, business travel to each of our nation's coast's. I have not had convenient internet access for much of that time period and have missed the comaraderie of this forum. It's good to be back. For a little while.

    I used a support very similar to Scott's to do my atx/mtx swap. Worked like a charm. I was able to leave the engine hanging in space while I dropped the subframe and trans. Then, with the engine still hanging, I jacked the mtx up to the engine, then the same process for the subframe. With that support, I never had to resort to using an engine lift for the entire project. Being able to raise and lower the engine while hanging from the supports was a key feature as well.

    Scott has some skills at the drafting table, I see. :thumb:

    Eye Bolt Load Rating

    Thanks for the different designs people have posted to the forum, I'm going to build one very similar to SDPATT's over the next week or two. :hail:

    As I was pricing out parts and viewing different deisgns, a big safety concern crossed my mind.

    Some support designs use two cross beams and another used only one to lift both side of the engine and tranny.

    As I was checking load strengths of the chain, eye bolts and clevis connectors I noticed a huge disparity in the weight loads. :omg:

    A typical Home Depot/Lowes 5/16-3/8" steel chain was good for 4000 lbs+
    A 5/16" - 3/8" clevis were good anywhere from 1300 lbs +
    The Home Depot/Lowes 3/8" unwelded eyelet was only rated to 225 lbs.
    I know that SDPATT's drawing calls out for 9/16" eye bolt which is significantly stronger, the point I want to make is I could not find the load ratings for the 1/2" or 9/16" eye bolts at either of the stores. There are different eyelet designs that drastically affect the safe load bearing of the part. My local Home depot and Lowes only had unwelded eyelets which are significantly weaker than the welded or forged eyelets you can get online or at a good hardware store. The link below shows a few common different variations and load ratings.

    Bottom line, Everyone has different standards and perceptions of what safe is. Simply looking at some of the pics out there of how people have swapped clutches will tell you that. Please make sure you check all of your parts every time you use them. Take the time and make sure you get parts rated for what you want to do. It might cost you a dollar or two more per part but its your noggin under there.:thumb:

    I'm a little confused by the picture. Do the 2x4s that run across the front support get attached at the 80 deg angle, or is it just the angle of the eye bolt? If the whole 2x4 is angled, then i have to notch the 2x6?

    The back support looks like it's just the eye bolt at the 85 deg angle, correct?

    Last, the eyebolts go through a 2x4 sitting flat on top of the 2x4s that run the length of the support?
