Need help finding small box blade rippers

[bolivier]

I recently acquired a home made box blade with a 1650. I can't seem to find any rippers that will fit the holes. Can anybody give me some suggestions? All of the rippers I am finding are 3/4 X 2 1/2. The holes on my box blade are 3/4 X 2. One is actually 1 7/8. After taking a closer look at my blade, it doesn't appear that rippers have ever been used in these holes. If I can't find any smaller rippers, I might have to enlarge these holes to 2 1/2. Thanks.

If all I could find were 2-1/2" versus 2", I would be opening the holes to fit the most common size.
As long as you were not restoring a trailer queen.

That seek looks like a real cheek pincher

Do the rippers only engage the top box piece or there a lower mount? If they only have to go through the top mount, I would notch the top of the rippers with a cutoff wheel in a grinder. It's easier, and it's not like your going to be replacing rippers often enough to warrent remaking the top mount.

There is no lower mount as you speak of. The rippers go through a 3X3 piece of square tubing. The 3/4 X 2" holes are on top and bottom of the square tubing. My wife had suggested cutting the rippers down also. But since the most common size is 3/4 X 2 1/2 I'm thinking my best option is to enlarge the holes.

Cutting out the holes would seem the best choice

[DoubleO7]

Being the common rippers are 2-1/2" and the tube is 3"sq. that is going to make the hole go full width of the inside.
If it is more than 1/4" wall, you won't be able to get 2-1/2".
If you can get 2-1/2" plus a few hairs, you might want to slap an angle iron or two on the outside of the tube (toes in) for reinforcement.

That makes sense. I would think just one piece on the bottom rear corner of the 3 X 3 beam. That is where it would take the most abuse. What do you think?

[Berwil]

Ya, bottom rear corner would be the place to add an angle. 007, which way is toes in? Is that spooning the angle around the corner of the tube which means it will have to be notched like the tube? I would run the angle down the back of the tube then face the other leg towards the rear, flush with the bottom of the tube. No notching required, just stitch weld it in place.

The top front will be the next wear point, could probably get away with plating the front with a piece of 4" wide flat stock at each cutout for reinforcement.

This may just be a silly suggestion, but why not just try some bar 2" x 3/4" bar stock as rippers? Around here the soil has so much clay that even real rippers just make slots in the ground much like what bar stock would do. Gravel is a different story.

If you really wanted to you could heat and pound the end flat and curve it to put a "blade" on it like a real ripper.

Actually I would weld both toes of the angle to the tube.
On the backside of tube, put one down low.
On the front side of tube put it up high.
Not wrapped around or spooning the corners.
