I just bought six 7/8" cup type freeze plugs to seal the tubes. Once I'm finished with the welding, I will oil the insides well and drive these in with a bit of sealer on them. Should be good for another 50 years; way after my time.

Mike you wondered which direction I am from Portland. I live in northeastern Ohio where the high temperature was a balmy 39.  How's that for the first day of spring?!? I also saw those frames in Gary's basement. 

Will, my 41 frame had 2 places in it where water got inside and froze cracking it open. It didn't rust through. I thought about pouring some oil in also.

A couple of things to remember is that in this day & age, the likelyhood of these bikes setting outside in the weather to rust is very unlikely  Most surviving Simplex's are living better now than they ever have in they're lives.  The model T cars are in the same boat.  The progression for most were:

New & the pride of the owner...probably the first car/motorbike they've ever owned.
Somewhat used....the owner has moved on to better things but can still get some of the value in trade.
Back of the lot (or shed)....most of the good has been wrung out of it.
Teenager transportation....kids get them running just good enough to have fun & abuse them.  The end is near.
New again....thankfully it's survived long enough to be found by a collector who brings it back to better than new.

The other thing to remember is a lot of the bikes use the right rear upper bar as the conduit for the tail light wires.  Plugging the tubes will prevent that.

Cotton, I'm a 180 degrees from you in reference to Portland.  I almost wound up in North Canton a few years ago when my former company moved my department there.

 how about these? look a lot like the originals.  My 1948 has 1/8 holes  at the lowest part of the frame right at the bend on the underneath side.

Tom ,

Those are close , but not exact . The ebay offering caps seem a bit more flat . Maybe I'm picking nits . You can see OEM frame caps in the rusty nuts pic below .

We might have discussed this before, but my 1949 Model K had corks in all the tubes.  The one for the tail light wires had a hole drilled in it.  Where these factory?

Most hardware stores have the metal caps as shown and some have them in black plastic as well. I also have noticed several frames with the cork plugs.

I figure that the caps on my bike were from the factory as they were in the tubes when I bought the bike . I wouldn't think that a PO would have installed them , but I may be wrong .

I think the corks were used to keep the wires from rubbing on the frame.  The caps I have on mine were old and rusty. I cleaned them up and painted them to match the tins. I am also taking any steel nuts washers or pinion gear cleaning them then blueing them then froglubing them to keep them rust free.   :o

How thick is that steel you are using for a motor plate?
