Default Re installing the springs on a PC model 7539 router...

...this is a heavy duty 3.5 hp plunge router - the largest Porter Cable makes. I used it for years in a table I made and it worked great. In order to use this plunge router in a table I removed the springs in both handles.

Now I want to reinstall those springs and use it for general routing not mounted in a table. It has been very difficult to try to compress these 18 inch springs back into their cylinder holes on the router.

The resistance to compression is so great that the springs buckle and fly out every time. Is there a tool that can help me do this, or a way to compress those springs back into the holes ?

I made a few experimental jigs and nothing works to this point.

To me, the solution would be to keep the springs straight as they compress down into the holes while they are exerting an upward resistance to compression. Not easy to to this.

I know repair shops probably have a dedicated tool for this, but I'd like to avoid bringing it in just to reinstalll the springs.

I contacted Porter Cable and they do not have any tool to do this.

Those who are familiar with a PC7539 should understand what I am talking about

Thanks for anyone's help.

Here is a crazy idea, Find some PVC pipe that goes over the springs. Cut into 2" lengths. Wire them back together and stack them onto the springs. As you compress the springs to a point that you need to remove the PVC cut the wires and compress to the next one and so on til you can compress it down to the last one.
Just saying,
Herb

At one time automotive supply stores carried spring compressors that resembled an overgrown pair of pliers. Some had closing bolts such that they could be cranked down as it were. A quick Google search of hand spring compressors turned a few photos but I could not download any of them. Another consideration would be vise grips with forked tangs.

These may be far larger than what your looking for though.

I recently took mine apart to clean and lube the tubes and sleeves. Yes it can be a bit of trouble to reassemble. For the life of me I can't remember what I did to make it go back easily. Tomorrow I will pull the router out and see if I can remember. Getting older has presented a few blockades now and then.
