Making a Replacement Backrest for your Wheel Horse

[Lane Ranger 10,472]

My sister has made a couple backrests (plywood board and upholstery also) for my old Wheel Horses.    She has used 3/8 plywood but I have seen other folks use  different types of materials.   Glued chipboard is not a good materials to use as the  embedded three prong threaded 1/4 x 20 clips ( I guess they call these T nuts)  that go into the seat back to secure the two screws will often come loose or work out.

 

 

 

 

I am posting pictures of two of the backrests my sister made for me .   The measurements on these drawings is what she used to sew up the materials for the seatback.

 

I will note that I took a picture  (last picture in this set)  of one of the early seatbacks and found it to be one inch wider -so you can take that in consideration if you want to when making.

 

This posting may help some of you wanting to have a seat back made or reupholstered.

Thank you Lane for the info on making seats for these tractors. You were the inspiration for me to make the seat for my 1054 that I haven't gotten around to assemble yet. I got a lot of good information and decided to get a heavy duty sewing machine to sew my seat and back. With everything we do to these great old tractors we need someone to show us we can do it if inspired by someone that's done it before. It's always the little things that discourages people not to try. I think mine came out really good after you posted your seat. I plan on making a new seat for my lawn ranger and these plans will come in handy I love the back rest.

Very Nice work Bob!      Somewhere on Red Square there is another posting about making the 1054/953 seats.  The internal wood pieces that were used on those seats and pattern I did  three or four years ago!

That very post is what I used to make the seat and back.

Good info!  I also have an early 60's original backrest on my 702/852.  The wood dry rotted and last fall I cracked it in half moving the tractor around my garage.  I'm hoping I can open it up and make a new wood insert for it while re-using the factory cover to keep the retro look.  Been trying to figure out if I should use plywood or a board?  I'm guessing true plywood is the way to go.

I think they even steamed some of those early backrests that had plywood to make a little bit of of bend on the ends.   Round the edges and sand if using your old  cover.

I haven't tried to disassemble yet, but yes, it does look to be curved.

REDRANGER you will find the old original seat covers are very dry and will cracks if you try to remove it. Mine was so dry rotted it fell apart in my hand so making a pattern from it was impossible. Good luck on that.

Thanks for the info.  Those are some great looking upholstery jobs.    I know it's a completely different assembly process, but if you don't mind @Lane Ranger, I'll add some pictures of the seats I have rebuilt.

The seat back on my C-101 was broken off and not with the tractor, so I made a pattern from another seat and fabbed a new back.  Mrs K does the sewing.

 

The Commando 8 seat back was broken off, so I just had to weld it back to the bottom and make new cushions.  I have found the back cushion with the WH Logo is usually OK, so I just add new cording and side panels.

Ed:   A very good addition to this post.   That two piece seat looks great.   My sister  is doing a project like that right now.  We are trying to save a WH horsehead logo on the back of the two piece black seat and  redo the vinyl on the sides.

Glued chipboard is not a good materials to use as the  embedded three prong threaded 1/4 x 20 clips ( I guess they call these T nuts)  that go into the seat back to secure the two screws will often come loose or work out.

 

Don't know how they could come out. The nut goes into the wood on the front of the panel and the bolt goes into the nut from the rear. There are different types of T-nuts

Garry:   The chipboard will some times come apart  when or if it gets wet, prongs  eat into chipboard but not enough to hold, and/or   not aligned properly,

The correct plywood is either marine cabinet grade or fine cabinet grade - look for material that has more than 5 layers , 7 layer cabinet grade can take being steam bent and is far stronger . If you can find a cabinet shop locally - those guys will have small leftover/drops around you can get for a song - the stuff in full size sheets is quite expensive .

 

Mrs. K isn't messing about - that Pfaff is one heck of a heavy duty machine for the newer generation types . Nice looking work on the seats folks , upholstery work is an art and takes a lot of time to get it right .

For anyone wondering what the inside of the original backrests looks like....  

 

I've made a new plywood insert, transferred the T nuts, reapplied the factory foam and put it back together.

My cover split on the backside under the metal bracket so I think we can sew the bottom back together and with some staples and duct tape, I can make it work.  99% of the cover damage will be hidden behind the back brace.

Thanks for posting these backrest photos Red Ranger!  Great details!
