Hi to all I just got a this 75-100 mm Nsk mechanical digital micrometer, and works very nice! but the spindle has a little play and like all my other micrometers, the solution is to tight a little the adjusting nut. But I can´t pull out the thimble, I turn it all the way out but it jams about...

Thanks for the comments! Gus you sure work fast! at that rate you will get your engine running in no time, great work! sssfox: I found the 4 jaw chuck for the RT too expensive!, that why I only get the rotary table without nothing else, Im planning to do some mods and work holding hardware...

Thanks for the comments! Gus you engine is looking good!, here is some progress on mine: I just got a rotary table, and no tooling or work holding to use it, so it was very dificult to clamp the workpiece in order to use it, but at the end I was able to do it using my lathe dog and some bolts...

I have used aluminiun foil ( +/- 0.02 mm) to shim my milling vise, and has worked fine until now, I have put up to 3 layers (+/- 0.06 mm). Make sure you shim with the maximun area. hope to help Saludos

Hey Gus you engine is looking great! Make a build post on the "work in progress" subforum so we can follow your build! I will be looking forward Saludos

thanks for the tip Mark! here is a question: any type of cast iron will work? as far as I know, there are several alloys of cast iron, what I mean is, there is a special type of cast iron better for this aplication, or just any cast iron saved from the scrap yard will work? Peter: if you look...

Incredible work! :eek: I really like your engine! where you get the plans??

Hello again! Now its time to mak the crank piece, out of 1020 steel: then I set a flycutter to cut the radius of the piece borders, first I measure the heigth of the shank of the flycutter in the V block, then: (heigth of the shank) - ((shank diameter)/2) + raduis of the total...

Thanks Todd and Bob for the good input! I finished the valve asembly, here some photos of the process: And here is the engine at the moment, because of manipulation there is finger prints and oil in the finish, but still looking good! The action of the valve is...

Hi to all I was looking for some cheap end mills for steel and see that a lot of them, their material is listed as HSS-AL This mean that the bits are Hss for cutting aluminium? or is some type of coating of some sort? They will work for steel?? Thanks Saludos

Thanks people for the good input! I have returned to class in the university so again I don't have so much time to spend in the engine. :mad: Todd: I use a die in the lathe, the trick to get the threads to the end is to flip the die, in the back face the cutting edge have no countersink and...

Hi people! I'm very happy about all of you for sharing your opinions! Im very positive about getting a set of gage blocks, the comments are very positive about this set, the precision of these block seems to be just perfect for home workshop, but how about the finish? i'm concerned about the...

your piece is perfect! excellent work!

I had a 6x4 bandsaw and is good to rough cut some small steel plate, but its slow, and because I broke a few teeth in the blade it jams a lot, so really is not very efective for me... the method I use more often and is a lot cheap (it only reuqiere a drill press) is to buy some 4mm drills and...

Hi to all! I would like to get a set of gage blocks to make calibrations on my tools and measuring practice, I would like to buy some good brand but they are far out of my reach, then I looked this import set on ebay around US$100 with shipping to my country. The cuestion is, is this set worth...

the mill complements the lathe, ofcourse you can do milling in a lathe but it need a special attachment and the work area is limited, the x2 mini mill matches the mini lathe, but if you can affort a bigger one, go for it.

Very nice wood grip Tin, I also practice airsoft here in Chile, and have made a real wood grip for my Ak, also several parts for AEG guns. Saludos

I have the same kit, and I have used the bigger one with a large bit describing a diameter around 2.8", the important thing here is the depth of the cut, it has to be very thin, otherwise you will jam the mill. The 1" maximun out of the box is to prevent you from destroying the gears, but the...

Thanks guys Hey Gus your engine looks great, the "show piece" stuff is no more that a good polish and some mirror like finish, put some sandpaper to your columns and you will see! And hey, dont get me wrong, I do not own any brown&sharpe or mitutoyo tools, it just my far away dream... Today I...

Just be carrefully with the speed, as the boring head acts like a counter-weight and with high speed will move all the machine. you cant put a boring head counter-counter-weight to compensate this, and like Brian sayd, just take a lighter cuts (make a rough bore berofe in the lathe or drill, an...
