Thread: 1948 John Deere Row Cropper Tractor Tires

I used two Dewalt 7 1/4 blades to get er done.
Check them out some of the 24 tooth blades have 3 different teeth one for each side and one down the middle, worked great.
I use these blades for most of my small work so have more than one around.
These blades are very sharp but seem to loose it quickly, at least that super sharpness you need for cutting clean treads.

One other thought you don't have to go by the plans use what you got.

Yes, I could think outside of the box and change things up some. So, thinking outside of the box, I figure to use a 5/32" Carbide End Mill Router Bit that I have and use my router table and not the table saw. Should do the same thing and still have nice cuts. After all, I'll have to use the router to round over the disk I'm making the wheel from. First I'll have to make a jig that I feel will be accurate and comfortable using on my router table.

G'Day Bill and welcome to the forum.
As above "htl" aka Bruce has a wealth of know how & experience; he's one clever creative model maker.
A number of the toymakers and model makers participate on both this forum and on LumberJocks so worth a look there too...

Cheers, crowie

Thanks a bunch Crowie.

I noticed on the Bushmaster Jig, he cuts both sides at once then flips one side. Much better idea than making a left and right jig. I like it and will make one to do my tires.

Thanks again.

Bill, “htl” is top contributor on the toymaking section of the forum, send a “pm” to Bruce as I’m sure he’d be more than happy to assist. Cheers crowie

Thanks again Crowie, I'll pm him.

Also, I was watching Brian Procter's Dec 13, 2017 How to make tractor tires for models --> https://www.youtube.com/watch?v=wshxSM9lF3s
and was wondering if he made any jigs to cut out the center of the tire before he inserted the wheel rim.

Maybe someone else has. Seems reasonable that someone has to keep down the number of errors that would destroy a good tire.

I've thought of a jig to sand off the tire cleats in a uniform fashion. I'll post a picture when done.

Bill, You could also leave a message/question on Brian's youtube in the comments section....

Here's a quick list of some of my wheel making projects, they're not for tractors but will give you some ideas, then I'll show some pictures.
And there's fellows here with much more knowledge than I.
Cutting out the wheels

Here is the jig I use for making wheels, may look familiar to you as I posted it out a couple a months earlier.

For the few wheels you are making you can do it the way Toys and Joys shows.
This was my first wheel making jig.

The first blog I listed should fit nicely with this.
Have a 3/4 plywood base, clamp to table.
Drill 1/4 hole almost through glue in a short wood dowel.
The wheel blanks you have made in another of those blogs will fit over the dowel and be centered.
You can now change the bit to a hole saw and it will be center of the tire, do not drill all the way through at this time, need to save that dowel center.

Doing it this way your tires can already be treaded.

You can now make centers the same way, just larger than the hole saw you used for the tire, sand them on the disk sander jig till they just fit in the center of your tires.
If you were to add just a bit of and angle while sanding the centers they could be wedged in for a super tight fit I would think, as I've never needed to try this.

There are tons of tips on my blogs and Dutchy has even more, but his are usually more high tech than my crud jigs.
Hope this helps and maybe some can add even more help.

There a hundred whys to get it done you just need to figure out which one will work for you and the tools at hand.

Hi b'z, Would you have a picture of the tyre you require?

Not having seen the plans, but tyre kerf dimensions are not set in concrete. All you need to do is alter the thicknes of the treads in accordance with your kerf. If your kerf is too thick you may need to reduce the number of tread or vice vesa for thin kerfs... Do yourself a favour and make some pilots out of MDF... it's easier to work with (if you look after your lungs) and will give you a methodology for when you graduate to real timber.

I have made a T & J tractor and here are a couple of pictures of the "raw" rear wheels...

If the attached picture are similar to what you want I may be able to make some suggestions.

The only thing I’ve cut so far is the disk for the tire. Seems life and other things same along. Good things to be clear, but, have priorities for a short while.

After fixing a bunch of stuff around the house, I was able to get back to my model tractor and its tires.

This is mostly about what I learned. Doing is a great way to learn.

I decided to build a jig for my router using some of the recommended You-tubes designs. But I thought using some of the extra bearings I had laying around would give me just a little more control (plus, I already had them). Like the You-tube suggested, I made some degree circles from hardwood to use on later projects.

I tested my jig using soft white pine. Later I found this to be a mistake. When attempting to cut across the end grain of hard wood, the router caused more chatter and vibration in the wood than desired. This did not show in the soft wood. I had to modify my jig to reduce the play between the wheel to be cut and the jig. The wheel to be cut must be tight against the jig for perfect cuts.

I used a router to get a flat surface at the bottom of the cut. I didn’t have a dado blade and all of the blades I had ended up with a inverted V at the bottom of the cut. That inverted V would not allow for solid gluing.

I used a 8” long 1/4” all thread between the degreed-ed wheel and the wheel to be cut. This allowed for way too much twisting between the two. I’ll modify the jig to be shorter or even get a larger diameter all thread. I’m including a picture of a bad cut of a wheel made from red oak.

The good news is that I had several wheel blanks and was able to make 2 sets that will make great tractor wheels.
