I bought a new Loadmaster keel roller trailer last month for my 1979 22' Revenge and this trailer came with 8 back to back keel rollers and a bow catcher / bow support device. Not sure what you'd call it but I have a photo of the trailer in my personal page. I did not like how the bow support device worked with my hull as 2 rollers were taken out of the equation so I made a dealer approved modification to it. I replaced the bow support with another pair of back to back 12" Stoltz keel rollers giving me a total of 10 keel rollers. Opposed to the remaining 8 back-to-back rollers, I found that I needed to raise the front roller about 3/4 of an inch and the rear roller (in this pair) is slightly lower. I'm OK with how I have this as it will do for just simple support over the winter but I want to secure it better for actual trailering.

This is getting into the fine details on this thing but for those in the know would you recommend I forget about using the bracket slots and carefully drill two bolt holes in the brackets to make up for the height difference and allow the bolt to rest on the crossmember or just use the slots and use shims on top of the crossmember to support the bolt?

Thanks for the insight.

John

Wow, great story and the boat has come a long way since you bought it!

I'm just an amateur, but I used the slots and put shims under the bolts to maintain my keel roller heights under my 18.

Mark,
Thanks for your reply. Appreciate the feedback as well. What did you use to shim your bolts? The cross member is aluminum and the bolt is stainless so I thought about maybe using a slice of heavy plastic like material or some other non-metalic material so as to keep the odds of corrsion between the two different metal to a minimum.

I just used small hardwood blocks...as I was in a hurry that day! I would think plastic would be better as it won't hold moisture.

Thanks Mark. I have noticed that some rollers carry a little more load than others and I think it's mainly due to the tolerances of the bracket slots. With the exception of the front pair they all rest on the top bolts which lay directly on top of the cross member so you would think they would be nearly level but the brackets are galvanized. Its not likely I'll get an exact match with each bracket, plus I'd guess the keel has its own minor variances. I think this Spring I wil try to even up the loads among the ten rollers using heavy plastic/pvc shims that I'll cut, sand, etc to fit.
