cab project

[JohnDeere4300]

i got the door almost finished today,need to do a little more welding.did get the window frame done on the right side, i am not sure if i will be able to glue tempered glass in these they do flex a little, maybe the glass will stiffen them up without breaking (any ideas?). or should i skin the frames & use gaskets.

Great work you are doing on the cab, i am wanting to build one for a
jd4300 but the windows are the problem i have. I can"t decide which
way to go right now. I have a backhoe attachment so the rear window
might need to be fixed so i can take it out sometimes. after seeing your last post about gaskets thats probably the way i will go.
I seen a post a while back (cab in progress) and he glued tempered
glass in. But you have a good point that it may flex some with the tractor.
Keep up the good work and the pictures to.

i dont think the windows will flex with the cab but the frames flex in and out and i dont know if the glass will be ok, if they will add strength when glued or if they will break. most crank windows on houses are only frames & they must flex some until the glass is installed, then does the glass stiffen them up? this is what i am wondering. for the rear window i am going to hinge mine to swing into the cab & latch up on to the ceiling that way it is out of the way but always there to let down.

well i did get a little welding done last night late 11:00. went to grizzly tools in a snow storm to pick up two new power tools for my shop and of course i could not wait till morning to play. used the welder what a dream after using an old lincoln stick for years.did make a couple cuts with the bandsaw works great but time will tell. probably wont get anything done today,need to get out & plow snow sure wish my cab was done.

I have that same Grizzly bandsaw and it's a great tool to have, especially when you need to cut miters.

Houses don't vibrate the way tractors do, so I wouldn't glue any windows in place. It will be a royal PITA to replace any that break. If you can avoid plastic windows, that would be good too as they will scratch badly with time requiring replacement. Attached is a down and dirty drawing of a method I'm thinking of using if I ever build a cab for my 4200. I've seen this method used on Deere tractors. The weather stripping can be obtained from McMaster-Carr. www.McMaster.com

yes this bandsaw is great but time will tell. i love the fact that the head angles instead of the clamp so u dont need 40 acres to cut angles on long pieces of steel. well i made up my mind i am going to skin the frame and window frames and use gaskets, this we know will work, the glueing might turn out to be an expensive education. glass is the only thing i will use.long term it will only need replaced if broken,plexiglass gets scrached and cloudy after awhile.

The swivel head was the selling point for me on the Grizzly bandsaw for the same reasons you mention about a conventional chop saw. Jet and Northern Tool offer the same saw now too. I like Jet's stand better, and Northern just had the factory paint it a different color.

Keep the pix coming on the cab project.

didnt get much done yesterday finished grinding,measured for sheet steel, gasket material,did some looking.might make a change to the swing open windows.the rear window cant swing in it wont clear the rops it will have to open out.i should be back at it next week need to order steel and run for supplies for the shop today.

Where are you going to get your glass from?

What kind of glass are you using?

I think using gaskets will be much better, you could take one out
if needed. when i start mine i will probably fix the back window on
hinges, so i can take the whole frame out. my backhoe attachment
stays on most of the time and it has a seat with it,and i don't have
much room to swing a window out.

keep us posted with your work, great job you are doing.


(I refuse to buy a cab from any dealer.)

i am not sure where to get the glass will probably use the yellow pages & have a glass person come out & do it. i plan on using 1/4 tempered glass. my side & rear windows will have bolts with lock nuts for the hinge pines. the side windows will open 180 degrees & latch at the back. the rear window will open out as far as what ever length the shock will be. with using the bolts i can also remove the windows.

well i got a little done today went & picked up 2 sheets of steel 16-gauge 4'X8' to skin the cab. i got a little side tracked when a customer came in & needed a snow plow built for a 100 ton rock truck. i couldnt say no he said he would help me,so an our later we had it done & it works great the customer was very happy. now i did get the one side window skinned still need to cut the opening for the window. does anyone know if there is a minimum radius for rounded corners for glass.i would like to round the corners so the gasket is all one piece with one seam where the two ends will meet.
