Use an angle grinder inside the channel to cut the bolts. An oscillating tool will take forever or longer. Just tried an oscillating tool and bolts are too hard. Grinding wheel goes right through them.

I pushed grade 5 bolts up from the bottom of channel, through the new subfloor and used nylock nuts. Not sure how you could do it without access to the underside. Had to have wrench on both sides to tighten.

One more quick question. Are you talking a 4.5" angle grinder? Would i just angle it down into the channel? I've found a few 2" angle grinders that would fit into the channel, but not sure they're heavy duty enough for the job.

Once the word is removed you can just cut them out of the channel. If your wood is still intact and surrounding the bolt then you may have to get through the wood first. But no, don't angle down through the wood. Remove the lower aluminum skin so you can access the tops of the bolts. Try the previous mentioned thread. My process involved my wood being so rotten I was able to clear out the channel of all wood leaving only the bolts exposed.

We did the same, but without the template.

On channel bolts I used a rotozip angle grinder with 1/16" metal cutting blade, nice angle cut through both bolt/nut until they simply fall apart. Very satisfying.

On doing blind floor attach, with belly pan on? Later Airstreams (My '73) used this type of floor fastener, I pre-drilled pilot holes and used a countersink bit on the plywood to accept the flat head - if you use these be gentle seating the screw, not much metal in the spars and I had one out of fifty or so strip the threads. The cutter-wings shear off on contact with the metal, I did not use them & snapped them off before setting fasteners.

It would be okay to increase the number of screws per spar, 8 or 10 inches apart, etc. etc.

If yoy decide to go the vise grip method be careful on the outrigers. They will bend. I use 2 vise grips. One tight on the bottom. The other on the top to wiggle.

My question.... We are putting in the back section of our floor on our 1968 Globetrotter. I know that this might be a stupid question but does the wall stud sit on the outrigger or the floor. No wood left to tell. Is the wood notched around the stud ot do we need to raise it? There was a L bracket from the stud to the rear floor.

Thanks
Steve and Deb
