Anyone interested in 83 Pace Arrow Tear down and Rebuild?

We've been a touch busy the last few days. More motorhome info coming in the next few days, though.

I am in the process of planning and making a bar top out of 2 slabs of live edge wood. Once built, I will be coating the top with epoxy. In looking at the various 2 part epoxy coatings made for this purpose, most, if not all, that I've checked out say they are safe for use on food surfaces..... this made me wonder about your use of the POR 15 and it's safety in use in an area that will have contact with food preparation utensils. Will there be possible issues with chemicals leaching out, chips or peeling of the POR 15 getting on your dishware , etc. Probably a small chance of exposure, but I thought I'd bring it up anyway

Thank you. I did call them at one point. The individual I spoke with said that they are unaware of any issues with it. However, since it has not been specifically approved by the Fda, Por15 tells people not to use it for that purpose.

Then again, looking at the Fda's track record, it makes one wonder, if their endorsement is as valuable as we tend to give them credit for.

In addition to that, Por15 can always be covered with Epoxy, or some other top coat as well that would be approved for contact with food.

That would give the strength of one, and safety of the other.

I did not test until the joint broke. My clamp was getting to the point that I did not want to flex it any more, so I quit the test at 104 lbs.

Yes, 104 lbs. That is 52 lbs per linear inch.







Since the sink is roughly 15 x 22, that means I have 2 sides that total 30", and the long sides total 44". Added together, we've got a total of 74 linear inches to split up the weight of the water to.

Even IF, I could fill the sink to 10" depth all the way around, (I can't because only 1 corner is that deep, while the shallow end is about 8") we can figure a couple of things.

15 x 22 = 330 square inches - not accounting for round corners. Then we can multiply by 10 for height, which will equal 3300 cubic inches.

There are 231 cubic inches in a gallon of water, so, 3300 / 231 = 14.28 gallons of water, times 8.33 lbs per gallon.

So, 8.33 lbs x 14.24 gallons = 119 pounds. If that is split up equally between the linear inches of 74, we only come up with 1.608 lbs per linear inch.

Since I just tested the wall to bottom glue joint at 52 lbs an inch, it looks like that joint should be fine. Again, that would be in a worst case scenario, with the sink completely full with a depth of 10 inches of water.

There was no fiberglass nor epoxy with what I tested, just wood and glue only. Fiberglass mesh and epoxy would increase the strength of the joint as well.

If I am missing something, please let me know.

Also, thanks for bringing the subject up about the strength of the sink. If you had not, I never would have tested this, and wouldn't know the numbers.

Here is my testing setup. I clamped a 2 x 3 to the wall, so I could apply pressure to the bottom of the setup.

I used a 24" clamp to apply pressure, with the scale at the top.

You can see the bow in the clamp beam, and yes it did spring back straight after I was done.

That's my setup.

You can see here that the piece of side wall is about 2" long.

These 2 pics are how the piece of sidewall is attached at the top to another ring.

The screws do not go through the piece of sidewall, but are just clamping that side piece by fiction, while I try to pull the joint apart.
