开云体育There’s a easier way of doing sleepers in a repetitive manner you make a
master with 2 pieces of copper wire set in it as per the attached diagram, the
mould will have the 4 holes in the bottom [which is the top of the sleeper] you
simply place the U shaped pieces of copper wire in the mould pour the resin in,
once it has set you lay the sleepers along and put the rail in place and use a
pair of pliers to crimp over the tips of the copper wire to form the dog spike
heads, the copper wire will eventually tarnish to a nice rust coloured
look.
You can also do the same if you want to make steel type sleepers.

Printing chairs on sleepers seems, to me, like a waste of printer
time and capacity.? Why not print just the chairs and then attach them to
real wooden sleepers?
Similarly, why keep printing lots of sleepers with little holes when you
could print a template that would let you drill accurately into several plywood
sleepers at a time and keep doing so until you have enough?? You could
print a similar template for drilling into plywood sleepers for points.
All it needs is a bit of thought to design the jigs to hold wooden sleepers
with the template above and - Robert's yer Mother's brother!!

I wish I could find the right rail section to make printing FR 'S-chairs' a
practical proposition - and the drawing skills and printing equipment!!
