I collected a number of old bridge bolts from a local railway that was decommissioned. Hard part is finding any two the same, there appears to be at least two diameters, square and hex heads, and numerous lengths.
Numerous tools had to be made including a curved butcher, 3 slot punches, a chisel faced drift and straight drift.
Never attempted a mortice and tenon join before but it has always appealed to me and I have been wanting to do this for ages.
So I designed this table as an experimental pieces to learn on before attempting a very large and complicated one I have drawn up.
Using a coke forge and hand tools, hammers and swages etc there is approx 22Hrs man hours in this. Which is two people doing 2x 6hr days with a half hr lunch break. Doing it all by hand requires a striker.
The bolts are 1" Dia. Two holes were slot punched then drifted round producing the swelling. The holes are at 60* and spiral up at 4" spacing. So the holes had to be in the correct order.

The stretchers are 16mm round and a shoulder was butchered in and then the tenon drawn out and swaged to 3/8" round

The tenons are heated in the forge then peened over. This is a major pain in the a$$ and can bend the stretchers requiring straightening.
This is one of the reasons I need a Oxy/LPG torch.

Still need to tidy up the heads of the tenons, and polish the thing up.
It's in need of a nice timber top approximately 600mm round or per side of an equilateral triangle. A nice natural edge burl would look good an inch or so thick.
