we're talking the small hand held tanks commonly used for plumbing? whats a bad idea is making a boiler without knowing how to design it or failing that not using a published design. There is nothing inherently wrong with using one of those, although there'd be a lot you'd need to do in...

Omnimill, you are right, it's goodto strike the right balance on the subject I've read those moderating docs and I think what their intent is is to bring some calm to the notion of handling and using them for intended applications; ie: that there's danger over 300C notwithstanding, they are...

Viton and IC is a scary proposition and imo should never be done. Read up on what the hydrofluoric acid does to flesh - it is produced if a fluoroelastomer, ie viton O ring is heated past 300C. Get a bit of hydrofluoric acid on you and amputation is how they stop it from burning. Maybe you or...

no apology needed, I was really just establishing credentials :D . Credentials in having used one....to clarify I am NOT the designer; as you noted it came out the mag and it wasn't my article. good luck with your build. if you can incorporate a counter weight it is imo a good idea; its a...

Hi Chuck, that HSM design above is a picture of the one i made (bob pinched it for his site). Anyway, I would just footnote the table rotating from this users perspective is a non issue; actually never occurred to me. Likely it doesn't rotate because of the friction between post roller on...

its one of those funny things, being doing it for so long one way, and with some tangible reasons for it, until this thread came up it never occurred to me to face inside to out. Not hitting the tailstock centre is good explanation of the one photo; I wonder where your instructor was coming...

I'm scratching my head wondering if we're thinking the same thing ....what do you find intuitive about it because imo its the opposite. there's lots of practical reasons for it, but the big one would be how do you start the cut if say you want to take 100 thou off? can't do that easily...

Facing should be from the outside toward the lathes axis.

Hi I've a number of accessories for the Emco Maximat lathe/mill.....vise, travelling steady, compound & 4 way tool post, fixed steady & a rotary table. Please email if interested. thanks thanks

I seem to be attracting a lot of negativity from you. in this thread you've said.... that's a lot of bandwidth just criticizing what someone else says and I not sure why it bothers you so. I find you often making cracks or criticizing the content of other posts... In this case I tried to...

poor guy? I think he got a lot great content around his question "teach a man to fish....." advancing an understanding of why things are as they are IS the best way to make model work look more authentic. When you look at the shape and form of a prototype, its not often by accident, its...

no drama MM, just was considered by some too OT I guess......it would have been my preference to have had it moved into the break room or whatever rather than locked....imo it was inoffensive and somewhat model engineering related

on the contrary, the discussion was quite relevant. Not because differing bolt tension is every going to be a factor in our models, but because the hobby is model engineering - what could be more germane than the discussion and learning of engineering; what goes into understanding a bolt in...

thats a neat little engine, keep the pics comming

I see what you're getting at, but I'm not so sure....the length having strain for both is the same, granted the stud has a section of threading under the nut, but chances are the bolt has the same entering the fixed piece, that's taking the strain past the nut and fixed piece as...
