Building replacement tables for Delta DC380 planer

I purchased this planer used a year or two ago and it came with the fold down particle board in/outfeed tables instead of the nicer roller tables. The guy that had it before me lost the hardware that attaches the metal table support arms to the stand so he attached some cheap L brackets and used those, however that causes the tables to be very unstable to the point where they flex downward when you apply even a small amount of weight to them. Naturally because of this, I have problems with snipe.

I haven’t really used the planer much since I bought it but when I have I just did the best I could and ran planed boards through my drum sander to get rid of snipe. I want to take some time to correct the root problem but not sure the best way to go about it. Ideally I would like to find a set of the roller tables, but I have been looking on and off for a year and haven’t found anywhere to buy them.

I was thinking the next best thing would be to create a stationary table 15” wide by about 6’ long. That would rest on the bed of the planer underneath the cutter head and it would stick out each end about 2’. I would put formica on it and wax it so it would be slippery and wood would not get hung up on it. Then I’d figure some way to attach it to the planer so it couldn’t move. Most importantly, I’d joint a couple of 6’ long boards and use them to reinforce the table so it can’t flex. The problem I see with this approach is that I’d lose about 2-2.5” of the vertical capacity of the planer. That isn’t a huge problem as I rarely plane anything thicker than 8/4 but wanted to throw this out there and see if anybody had a better idea.
