Cutting down a sprinfield seat post

[PhilM]

I am looking for information about cutting down a springfield king pin seat post. :?:

Pretty sure it won't work. I've thought about it, but both ends seem like they shouldn't be cut.

I thought if I cut the top portion at just below the insert and remove the insert from this part I would reinstall it in the shortened shaft

If you can pull that off without messing up the insert it would probably work... you just hacksawing it?

since it is aluminum I think I will use my chop saw

I thought about using a pipe cutter... if I had one that big. They make super clean cuts

I went to BPS today in Aurburn Hills and picked up another seat post. When I got home I measured down from the top inside to get the measurement of the inside nylon bushing that was about 3" I cut the post at 3 1/2" from the top using my 10" miter saw with a carbide blade. (the cut turned out clean and straight). I then used a bearing spreader to clamp the outside of the cutoff post and using a bearing driver I drove the insert out.

After getting an accurate measurement for the finished post size I re-cut the bottom part of the post and reinserted the nylon bushing. I started out with a 13" post and finished out with a 6" post.

I have cut down a couple swivl-eze seat posts. I used my miter saw with a carbide blade to cut them. The inserts are about 2 1/2" to 3" long, if you are cutting more that that from the posts you can drive out the bushing to reuse it. If you do damage your bushing you can buy them from Grizzly Jig Co. (https://www.grizzlyjig.com) I don't see them on the website, but the catalog shows them. They are about 5 bucks or so.
Good Luck

Did You Take Any In-Progress Pics? :?:

PhilM,
Grizzly jig also carries the seat post in a 6" length. They are the only place that I have seen them on the shelf. I have made a couple double seat rigs for crappie fishing that I have used the 6" riser on. Glad you got yours finished.

no I did not take any progress pic's, sorry.
