When I converted the cam to a straight cut gear I slotted the bolt holes which makes the gear adjustable.
Under the button head bolts in this pic the holes are slotted which allows the gear to be advanced or retarded.
When you get a non adjustable cam from the factory your stuck with whatever timing the cam was manufactured with, which can very.
Like this whole build, that’s awesome. I have a crappy DCEN tig, I’d love to land a deal like that.Kinda strange how things work out sometimes.
Ive always had to use a friends tig welder which limits my time and experience with them.
About a month ago I shot a guy an offer through craigslist on a welder he had. He declined my offer which was 300 less than the asking price saying "he can't go any lower because its worth twice as much".
Yesterday he emailed me and said its got to go so I picked this up today.
Story is its an ex Lawrence Livermore Lab unit that was purchased new in 1990 and serviced every six months. The seller worked their and used it until they replaced it with new models. He liked it enough to purchase the unit, but its only sat in his garage since.
I talked to an ace welder that recommended this model to me saying it will do everything you need and parts are much easier and cheeper to replace than the new ones.
Took me about 10 months to get ahold of one. Total price was $1000
Its super clean inside and out and has the optional pulser and water cooler. I think I found the right one for me.
Now I can spend the time to raise the ports on a 390 to the heights Ive always wanted to. This is going to be cool.
