Re: Homemade Spring Spreader
Admiral, I like the ingenuity & engineering of your spreader! Never having used one I'll leave all comments RE:safety & practicality to Barners that have. Looks good!

I used the threaded pieces (rolled threads for strength)that came with the Turnbuckle and welded and sleeved them to the main bar. |

Re: Homemade Spring Spreader
Wow, now after all these years spending extra $ for grade 8 bolts for their strength , I find out Kube says they are too "brittle". I can't wait till he posts a picture of his spreader.

Just as Kube said, just because you haven't had one of these fly apart on you, doesn't mean it's not about to happen. And, remember, "watching for bending" and backing off before things get hairy may not be such a good safety plan, as these failures happen fast and you could end up with a face full of shrapnel before you know what happened. You will NOT be able to get out of the way fast enough. Trust me. I'm not attempting to come across as any kind of know-it-all here, just spread some industry knowledge I have on machine design, metallurgy and working safely - all of which are required in my business on a daily basis. |

Re: Homemade Spring Spreader
Here's a pic of the one our club owns, although it is a poor pic. Sorry for that.

Re: Homemade Spring Spreader
I know this is not home made but, thought you might want to see an old Snap On spreader

The yellow one is a SnapOn brand spreader. All steel, you can easily see it is heavy and built well. The threaded portion is a full 1" diameter. The "skinny" one is KD, another early production tool. It is also all steel. Threaded portion is 7/8" diameter. I like the way the ends are shaped on this one. Lastly is the one I made. The threaded portion was made from one piece of StressProof® steel. It is 1" diameter. I cut #8 (pitch) threads in it. The outer sleeve is thick wall steel tube. It is not rolled and welded but rather a formed piece which is much stronger. I have a number of sleeves that can be added to this as needed for various widths of springs.

Re: Homemade Spring Spreader
OK, I'll add my comments to this thread..
Attached is a pix of a spring spreader that I made many years ago... I made it from memory of the one we had at a Ford garage I worked at in the early '50's.. I used 3/4" threaded rod and 1" pipe.. The design I used requires only simple shop tools and a welder to weld on the ends. In reality, the spreader only has to expand a very short distance to relieve the tension on the shackles.. It should be noted that I "concave ground" the ends of my engaging blocks to capture the spring eye, the blocks can not disengage from the spring eye, once pressure is applied to the spreader..

Re: Homemade Spring Spreader
Yes, I agree, Kube's tools sure look sturdy.

Re: Homemade Spring Spreader
Since we are posting spreaders... I picked this one up a while back for a fair price. Does anyone know what make it is or seen one like it?

Re: Homemade Spring Spreader
Interesting, you must be one strong dude to work that with the short handle on the wrench! (I know, you probably have a pipe cheater bar to slip over the handle)
I thought for sure Kube would have a KR Wilson spreader. Another thought on the home made ones, the threaded part should extend as far as possible into the hollow part so when in use it will minimize any tendency to flex/bend. |

I do own a KRW spreader. I couldn't get to it this morning. The basic difference between the KRW tool and the one I made is the KRW tool has chains integral on each end that were intended to be wrapped around the spring. Kind of a safety thing... The spreader that I'd made has numerous sleeves that can be added as required. i add them to the smooth end, that is the end that has no threads. In that way, I need only the minimal amount of threads protruding from the outer sleeve as necessary to spread the spring. Even utilizing 1" diameter stock, the end with threads will always be inherently weaker than the end that remains smooth.

Re: Homemade Spring Spreader
The cast wrench was broke when I got it. Still works well and a pipe / torque amplifier can be used. Or just a bigger wrench...

Re: Homemade Spring Spreader
I like this one for the 34 rear springs.

Re: Homemade Spring Spreader
I think I need to hang a "torque amplifier" up with my tools and label it as such! Thanks!

Re: Homemade Spring Spreader
I pretty much copied the one illustrated in the V8 Times. I used 3/4" all-thread and kept goofing with it until I had the maximium amount of all thread captured within the black iron pipe. Worked and worked well, however it still deflected a small amount. 1/2" all thread has no chance...
