I don't know the cfm requirements of your hammer, but I would check out a
number of things.

One it sounds like a single stage compressor. Probably fine for some
painting. and light mech. work.

on a single stage the 115psi is max, it usually kicks in around 80-90
depending on your setting and then shuts off if it reaches 115.

IF YOU CAN AFFORD IT I would recommend a 2 stage compressor even at the 5
horse level. it will cycle between 125 and 150, so you can set a regulator
to provide continuous 90 - 110psi service.  This would make the output of
your hammer more predictable than if the incoming pressure was all over the
board.

Two other things to consider, are:

1. Bearings You want ball or roller bearings, there is no oil pump. all
circulation is by splash system and that just does not get the oil into
oilite bearings. They Die.
2. Cast Iron heads. are usually better than cast iron sleeved aluminum ones.

 Does anyone have any experience with this type

buying one and replacing it with a Q or an IR triples it?

I am interested in seeing one of these hammers or the plans.
