This the program that James Perry turned me onto . You can download Mach-3 and follow the tutorial .. next thing you know , your ready to crash some end mills ..
And as vnemous pointed out , less likely to get BBQ sauce on it ...
Welding is about timing and depth perception . If you can play a musical instrument and/or sew with a needle and thread in the dark ... you'll do fine ..

A lot of the parts and pieces that AZ posted were fab up by my son . I always taught him to trust his numbers . That whole , just a little more mentality will put your parts all over the board ...

It seems no matter if I ran my bar thru the mains , clamped blocks and fronts together or on my surface plate , the parts will still move around a few thou from major welding . I recently built a machine that surfaces up to 36" long ...
Water ports erode pretty bad and where the cases bolt together are pretty mismatched from the factory these days ... not no mo ...

The decked block brings me in a little tight ....
The removable chamber heads we developed for the big bore motors make it easy to set the final quench distance .
I have a few different chamber design's we are going to work with as well . First set will be a bit on the conservative side ..

The MACH3 tip is much appreciated Sir. The welding on the other hand ... Momma says my timing stinks and the eyes are already using accessories so that could be an adventure.

Is that a Glidden rag? Did you close the deck on that block? These for the 25 Motion?

I'd be happy to external plumb to avoid water across the deck

Your welcome .. but like I said , James Perry turned me onto it . I'm just passing it along ..
I wear a 1.25 so I can see where I'm going . Then my helmet has another 1.25 diopter lens so I can see what I'm doing once I get there ...
I'd much rather be out in the open ....
Than playin poke ~n~ hope down at the bottom of a dark hole ...
Couple low spots to deal with on the "easy" side before I plunge cut the floor in the picture above ....
Power , Power , Power ... I never mentioned I was building a "line bore" .. so don't get too far ahead .. Actually Merc says .. If it has 2 dowel's , take the top 1 out and see if it spins , if not , take them both out and give it a try . If still no ... try another front half ...
I was talking about dealing with high spots , wavy "pan rails" and area's that tend to erode away ....
The part has to be flat before you can scribe a go~no go area ...
And these 3.0L tend to erode the lower stud on the midsection where the little ground loop wire goes and the two short studs on the block , right below the coil mount plate . Actually , those three NPT ports by the base rot away too ..
This ones in pretty good shape . It's here to be bored . But I get blocks that are pretty new and in great shape , but leak water around the water jacket ... I gotta be able to fix it ..

Yes it is ... Deck rings , but not sealed ... Yes they are ..
A while back Merc came out with a service bulletin where the block is torqued down in three steps . On the last step , you only do 8 out of the 10 studs . They want you to leave the two studs below # 6 cylinder back at the second torque value . Seems that the blocks are so *******weak , that it pulls # 6 out of round if you tighten all studs evenly ..
You know I couldn't let that go ... so I build a little integrity into them for those that want it ...
And yes , the exhaust is a little ... ahhh , different .

Always a treat to get a glimpse into your world Chaz. Sad note though...I'm only MAC capable so MACH3 is problematic.
