Boring bar options for 3.0 litre mercs

[LongShot]

Dave,the T slot is attached to a lead screw that comes out of the rear of the main housing.The whole machine can rotate 360 degrees around the stud,plus move in or out a couple of inches,one turn of lead screw and its tight,very fast.On a V8 you mount directly to the deck,bore two holes from the one position,just rotate.Then move down and do the other two.

So the knurled knob on a V8 would be attached to the rod connected to the arbor running through the mains? The lead screw on the machine actually tightens the knurled knob down on the t slot rail? I might be getting it wrong but just interests me as I consider a different style bar.

Well kinda,The knurled knob is one of about six,in the tool kit,each one having a different thread.When doing a V8 you would select one that is the same thread as a head bolt,and screw it into the deck,between two cylinders.Or there is another fixture where the knob is a long bolt that screws into a Crossbar at the bottom of the cylinder.All that is needed is a T that the T slot can pull up on.The lead screw pulls up on the T bar witch pulls down on the boring bar and locks it to the deck.

Yep. I don't use mine as a portable but that arrangement is better than the van norman t bar and clamp. Keep your eyes and ears open for vn 777 or 777s parts.
It is interesting to indicate in the perpindicularity of the bar bolted to a parallel ground plate. The bottom of the boring bar housing is not perfectly true. I had to shim mine .006 to get it trued up.

Ya have to watch buying a used machine.Most are over fifty years old,and they are very clumsy,and heavy.Quite often they have at some point fell off the stand,and can be sprung a little out of alignment.Most are not serviced any longer.

well here's mine.flip table(ground) makes mounting the blocks a snap. i made t.plates to fit xflows and mercs. im still working out the exact procedure for running it,but i got plenty of junk blocks to play with.so far its worked really well,just gotta put a new feed gear in the 777.

Truer words have never been spoken. Mine came from a formerly "the best shop in town" machine shop. It came with an 048 table, an FN, and an FWS2. Pneumatic centering and a float clamp. First on the agenda was to replace the boring head as it was trashed by the last repairman who did not bother to seat the bottom race. Wonder why their reputation went in the crapper. Followed by the removal of the pneumatic centering (what a joke) then the float/clamp. Final alteration was to replace the gears in the FWS2. The shop that had it was a family owned shop that had their kid running the place. I bought several machines from them when they went down and have had to rework/rebuild every piece.

Rock what is the range of the fws2? I worked on my. 777s today and it is going to need a set of shoes and thrust washer. I also have to buy all new tooling for it. There is an fws2 for sale locally with the triangular table and all the plates to do Harley jugs from shovel head up to the EVO. Figure I could sell stand, Harley fixtures and part out my two van Normans and come out.

My FWS2 bores 1 3/4 to 3 3/4 with a 12" stroke. Iffn you want to do blind bores you might freak on the cost of a cutter. Ain't pretty.
Hope all is well Dave.

I know what you mean. Looked at one for an FN at Beam and it was $150 with indexable cutter. I am non-proficient at silver solder and green wheel so the replaceable inserts are the way to go for me. Just got off the phone with Cavco and new expansion jaws are NLA. Reminds me of Mother Merc. Left you a PM. Give me a ring.

OK, you guys with a kwikway bar,most of you know that kwikway is out of business.At some point you will need this information.A fella in Texas named Craig Coder,(Coder parts supply)214/707-0984 has taken over,and is supplying tooling and some repair parts.His plan is to service these machines long term.So put this number away,at some point you will be glad you did. - BTW Kwikway blind hole indexable tool holder new $135 Ebay free ship

[rock]

Wow. That's what I get for calling Kwik Way for tooling and not shopping around. I had one made by them and it was well over $300. Sharpening wheel for FN was also absurd. Thanks for the info.

+1 for Mr Coder...Fast courteous service and a very fair price...especially considering he's really the only game in town,and 30 years Kwik Way experience to boot,Chris
