Am considering making custom springs and am wondering if anyone has any suggestions on spring making machines?

Coil type extension springs.

I'm asking this purely from an inquisitive standpoint as I don't know a whole lot about coil springs, but....
Springs for what use(s)?
What sizes of springs?
Are you set up for heat treating the steel, and do you have a way to accurately temper it?
Is this for personal use or for sale?

If you are making springs that are using 4mm (1/4") wire or less, you can use a metal lathe with greased wooden leaders on the tool post to feed the wire onto a mandrill. I have mad springs from 1/8th inch diameter from /.035" piano wire, to 1/4" diameter wire springs 2 inches in coil diameter. It takes a bit of practice and tensioning of the wires, but it works very well. Jim

No experience with the machines, but that sounds like a good business to get into!
I needed some special springs for a machine I was rebuilding a while back.
I thought no big deal, just have some made...
OMG!!! I got some of the most ridiculous price quotes! You would have thought I was ordering something for the space program! That is the quotes I was able to get, most just didn't bother to respond.
So there is definitely room for some competition out there!
BTW, I ended up buying a roll of music wire, winding the springs on the lathe. They weren't real pretty, no 2 alike, but they were out of site, got the job done for a tiny fraction of the cost!

Small coil springs, using music wire that does not have to be tempered It only has to be "relaxed" after coiling which only requires a counter top broiler. Common uses might be throttle return. carburetor, etc. The type of spring I would be making would not be suitable for valve springs or other uses in a high temperature setting. I do not have a lathe. A lathe with a threading attachment, and a new spring coiling machine, are probably about the same price. I have not talked to anyone that has used one of these hand turned spring machines and was wondering if anyone out there had.

I make a double torson spring by the 100,s from 11 gauge oil tempered spring wire. I buy the wire in 100 lbs rolls.
Wire is cut 42 inches long and first bent into a u shape , then both sides wound with 3 i/2 turns.
Started with a homemade jig on a metal lathe and soon learned this was a good way to lose my fingers.
Designed another hand powered roller to make the springs. and have made in excess of 4000 springs with this wife powered
homemade spring winder.
I make these springs for the Easy-Plant Jab Planter sold by Johnny,s Selected Seeds.
So it can be done but spring wire is tough and hard to bend and cut and dangerous to work with.
I use oil tempered wire because when unrolled it will straighten out but Music wire remains coiled and has to
be straighten with a straighten machine with I can.t afford.

I have wound springs on a lathe. made a fixture for the compound rest that would feed the wire up close to the mandrel and the mandrel slid through a ball bearing mounted next to the wire feed. Then set up for "screw cutting" the right "pitch" for the spring you want. The spring will come out a little bigger than the dia. of the mandrel. At the chuck I mounted the mandrel in a bushing that went into the chuck. In the bushing I drilled a hole to the end of the wire with a 90 deg. bend in it to hold and start the spring.
