Creeker,
Why don't you even harbor the suggestion that you visit and pay to ride the EBT? And join the FEBT? Your muscles could well be used to spike some of the many ties that were installed two weeks ago.
If you can not lift and swing a ten pound maul, you can be very helpful if you handle a heavy hammer and set the spikes solid for the air gun or the maul in someone's else hand. The most hazardous part of building track is getting the spike started and into the wood and solid. As you try it start driving the spike, it can shoot a long way off and take out a leg or eye. Eye protection is required to drive spikes, as well to pull spikes.
The hazard in pulling old spikes is the head can break off and hit you in the eye. While being the Supervisor, I had two employees (out of 125) who came to thank me for being so strong on those rules as they showed me their broken safety glasses being hit by the head of the spike. They got new goggles. This was within the short period of three years that two eyes were saved.
Do not watch spikes being driven without eye protection as metal flakes (mill scale) can break off and fly into your eye.
For those who need to buy spiks for 3' gauge railroad: they should buy 1/2" by 4 1/2" spikes from Keystone Spikes Company, Lebanon, PA. They are sold by Pohl Corporation at 610-926-5400. Expect a shock regarding the price inflation. A 200# keg has about 303 spikes including a few headless. 5" or 6" spikes for SG track are not required for narrow gauge.
The next work session will be aided by having a battery powered 1/4" drill to pre drill (only 1" deep) the old died wood. This makes for a safer job. That is a good job for some guy or gal not able to swing a ten pound maul. There are jobs for all level of person ability or body style. I hope Creeper will join and bring his buddies as well.
Once you learn what you are into, those dreams have a different perspective.
