Anything will rack if you only have pressure on one side of it. Those vise screws are pretty inexpensive, it might just be worth it to get two and put a wagon vise on each side at the end. I assume you’re looking for the benefit of having an end vise with dogs on the top of it so you can clamp large panels?

The racking may be minimized if there is no play between the wagon blocks and the block openings. But still, there will be at least some racking. I agree with Jimi C; use separate vise screws.

yes the idea was having the option for large panels

if i ever did this, i think i would would bias the screw toward the front (since that “jaw” would get more use) to minimize racking there and when using both racking shouldn’t be an issue on squared boards

BUT, you guys are right, at $35 for the screw versus gobs of hours trying to convert my sketch into something usable, it’s a no brainer to avoidall the potential issues

thanks for your feedback!

I’d have to agree with all of the above. When clamping something square in a twin screw there would be no racking. What I like about have two independent wagon vises is for clamping irregular panels. I onlly have one wagon vise on my bench and wish I would have put 2 independent ones.

I think it’ll bind like the devil. Cool thought, though.
