Making a female pto shaft

I have a small metal tubing shaft that goes to my dads tiller. The female end is a little too short and when I get on uneven ground the
male shaft is on the very tip of the female shaft and breaks the female shaft.
I cant find the female tuning anywhere as it seems to be an odd size.
Is it possible to make some tubing? How would I go about doing that? I am not an expert metal worker, but I do have some scrap metal around, a set of torches and a welder. The shaft only needs to be about 20 inches.
Can I somehow tack a piece of plate to the male shaft and "bend" a piece of plate around it to form a tube? I am guessing that I could not get the metal hot enough along the whole 20 inches to bend it though.
How much difference in size does the pto female shaft need to be in size related to the male shaft? I assuming too small and it will not slide in and out, too large a gap and the male will just sit and spin inside the female shaft.
Any Advice is appreciated!

I assume you are refering to a tractor pto shaft. My 5 foot slasher has a pto drive shaft shaft is square cross section and there is no steel supplies standard size box tubing that will fit it properly. The local tractor supplier had the right female drive shaft with the correct size inside square and a round outside of the shaft. It is much heavier duty then an offcut of box steel and will (according to the salesman!?!) provide a longer life than mild steel. As I use my (heavy duty) slasher like a rotary plow and lantana destrustion device and have a heap of rocks in my paddocks, it was worth it to have a machine that is realible and allows me to advertise to all my neighbours that I 'm playing with the slasher...... If I leave the back plate open, it will throw a brick a couple of dozen times further than I can.....
The local engineering shop cut off the old worn section and welded it onto the original drive shaft and kept it in line in the process. The drive shaft was about $28 for the required 20 odd inch length, and about $20 for the welding.
You may be able to weld it on yourself, and if the diameters are the same, a simple piece of angle iron held in a vice is enough to give you a welding bracket, if the diameters are different, a bit of offcut sheet may provide suitable packing.
You will need a long enough piece to provide slide movement throughout the lift range of the tractor, and engage enough at the outward extreme travel and so the male does not bottom out inside the female piece at any part of the travel. Pack grease into it to provide lube and rustproofing.
Hope this helps, Peter

I run a fair bit of pto implimpents and the local driveline shop carries most common parts. What dimensions do you need? Is your tiller properly mounted? Check out these guys for mail order stuff http://www.valu-bilt.com / or http://www.agri-supply.com/catmain/catmain.htm
Not sure how much HP your dealing with but having a pto assembly fail behind you under load can ruin your whole day, not to mention the back of your head.....I've had em grenade with a bang. If the tubing is an odd size you might have to replace the male to get a matching set up. Be safe when dealing with pto's and follow all the safety rules.

For USA made PTO drivelines; I usually figure out what I need from Drawings and Part numbers on G&G Mfg.'s web site: http://www.ggmfg.com PTO Components page: http://www.ggmfg.com/product_subcategories.asp?cat=pto_drivelines
Once, I know what I want, I have one of my local Ag implement dealers order the correct component from G&G. I just got a slip-sleeve, part# 194-3500 for a 35N PTO to weld into the female tube. The slip-sleeve accepts the male shaft. You can use the slip-sleeve to change the length of your female tube. Tubing is also available. http://www.ggmfg.com/product_subsubcategories.asp?subcatParent37&catPK=7

The old shaft's slip-sleeve broke out in a manner similar to what you just described.
If you have a UK or European made drive line, try some of the previously mentioned Ag suppliers for tubing and parts, as well as, local ag dealers.

What size is it? If it's a small tiller, chances are it's foreign, quite possibly Italian. They tend to use metric PTO's, usually Bondioli and Pavesi. European uses a lot of Walterscheid. Is the shaft rectangular, "lemon" shaped, or 3 lobed?
Any good local agricultural dealer should be able to fix you up. Where are you located? Is there a Driveline Service anywhere near?
