It looks great. I hope your testing once it is running shows a great improvement in rigidity. If so, I'm going to consider doing it on my PM-30MV based on your excellent video.
Thinking that rigidity only improve a small amount as it orginally is a rigid machine but this damps vibration much as the hollow space there. Should have some grease on wooden plate surfaces for easier removal.
Hi RayChar C Yes the machine is rigid by comparison to other machines on the market. However when your dealing with a linear Rail conversion the slightest flex will show up . The Epoxy Granite fill adds the needed Rigidity, stiffness, dampening, and extra weight. I did use Grease on the forms for easy removal Yes.
That was very cleverly planned box mold you made there with those relief cuts and other quirks applied to it. How much were the castinite buckets cost?
Nice work! I have one question that you might be able to answer. Is that base plate of the column welded on to the column (of steel?) or is it all one piece of cast iron?
Some CNC machines use epoxy granite for the entire machine frame. Where I work we have a couple Hardinge lathes built on epoxy granite bases. They regularly hold 3 micron tolerance.
It depends a lot on the machine, the brand, and their design goals. In many respects it is equal or superior to cast iron, especially in vibration dampening. More relevant to this discussion, it's orders of magnitudes easier for home shop and hobbyists to work with since it doesn't require massive moulds and foundries capable of casting a machine tool out of cast iron in one fell swoop. The process is somewhat technical, and requires a lot of reading and research if one wants to do it correctly, and there's tons of different opinions about methods, materials, resins, and other variables that people love to debate over. In the end, I view it as another very powerful tool that can do amazingly useful things in a home shop environment. It seems ideally suited for the diyer that doesn't have access to a whole shop of high precision machine tools, but does have the ingenuity, patience, and determination to bootstrap their own precision equipment and systems.
No, I'm married. But I tend to stay in the dog house a lot. I use to ask for forgiveness rather than permission but I have about ran that well dry. I need a new game plan.
@@halfstep67 Have you tried blackouts and lost time? I was busted for curing powder coatings in the kitchen oven. Yeah, it didn't fly there either. Curiously enough, I now have that very oven in the shop now. Credit card took a hit, but she would have never sanctioned the shop oven otherwise. Crazy? Like a fox......with a prenup and a good attorney.
Actually for me it was easy decision, Its good to have friends. My buddy Chris had already done all the leg work and research. He shared with Wyatt and Wyatt shared with me. Time is something I've been in short supply of so having a premix to take all the ratio out for me was worth it.
@@davidnaisuler5743 maybe, but there are different types of nonshrink grout I'm sure, and some might work, and others probably won't. Which ones did you have in mind? I'm familiar with Moglice, and have seen it used in rebuilding ways, and I think used as a leveling and footing agent to go under a linear rail, but I can't think of any other grouting compounds at the moment. I'm hoping to build some of my own machining equipment over the next few years and I'm always eager to explore new ideas and new systems that might work better for what I'm trying to accomplish. The Epoxy-Granite has other properties beyond the nonshrink and added mass. It also adds a significant amount of vibration dampening to the machine because of its specific matrix and composition.
I've learned to stay away from anything that involves dishwashing. So be careful. You get caught wearing those dishwashing gloves and the next thing you know, you will be washing dishes.
Why don't you just bolt the machine to the floor and fill it with grout like the good lord intended? 15 bucks, no crazy chems, drill mixer and a 5 gal bucket, easy cleanup, bob's your uncle.
Can't wait for the before/after comparison!! I might do that on mine as well. Good job Sam.
Very happy with the results
Those relief cuts were inspired. Looks like a great result, very nice.
Thanks Yes made form removal pretty simple.
Hi and thank you very much for posting. The information is much appreciated. Good speed with the rest of the build!
Glad it was helpful! Thank you!
Good job...👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼🇧🇷
Thank you!
What is your aggregate made from ? What are the sizes of the ingredients ? How many % of epoxy and what epoxy you used ?
This was a Pre Mix

Considerably more ridgid

can this machine mill 4140 steel and 316l stainless steel easily ?
yes
Can't wait to see it run. Nice work
Same here!

One piece cast steel
@@CNC4XR7 Thank you for taking the time to reply :)
@@thechipwelder1253 your welcome
You should place a tapered shaped box inside form with mould release agent on the outside, then it will be easy to pull out!
Great tips thank you!
Is epoxy granite base what industrial cnc machines use?
Industrial machines are grouted not epoxied.
Some CNC machines use epoxy granite for the entire machine frame. Where I work we have a couple Hardinge lathes built on epoxy granite bases. They regularly hold 3 micron tolerance.

Agreed!
You could have used your wife's Kitchenaid mixer. She wouldn't have minded. Wives are very understanding about those things.
You Must be Single LOL!

Hi, I was wondering how you made the decision to use a premix such as Castinite? Why not buy the resin and quartz separately? Thanks for sharing!

@@CNC4XR7 Awesome, thanks!
No Problem
great video! Do you mind posting the approximate cost of the castinite mixture?
$140 Is what I paid contact them directly shipping will vary I'm sure.
Great Work!!!!!
Thank you !
Interesting stuff! How much is that stuff?
it is expensive I think there are other alternatives
Hello, how long does it take to harden?
a few hours and I let it cure overnite. it has a about a hour work time.
Awesome! I'll be interested to see your conclusions.
100% better on rigidity
very good video..very thanks
Your Welcome!
Nice job Sam!
Thank you
how about cement instead? Or plaster?
Not stable enough as it will shrink we want to stiffen the base and ad strength as well as weight.
non-shrink grout, 15 bucks a 50lb sack, it's what the rest of the world uses.

How much that stuff shrink?
If that shrink it was helping nothing for rigity
Doesn't shrink havent seen any issues
Wax paper works really good to just tape or hot glue it on the plywood
I had thought about wax but the grease was quick. Great tip thanks
You left the ball screw in while doing all this? Are you sane?
No It was removed Certianly
EXCELENT
Thank you!
Tips: Use dishwashing gloves to avoid breaking the gloves. They are cheap and weary robust.
Yes those would have worked better but these are Cheap.

@@halfstep67 right
It's been three years
Unfortunately yes it has. To many projects
Use wax for release
Wax yes That will work.
Easier to mix A&B and then mix with gravel.
This was a Premix Part A was already mixed in I only had to add part B
I follow !
Man you sound like snoop dogg
Really? Hmm interesting.
Wonder if a lady pleaser wouldn’t vibrate it better
Well I'm not sure but it would look real funny holding that up against the base!
Why don't you just bolt the machine to the floor and fill it with grout like the good lord intended? 15 bucks, no crazy chems, drill mixer and a 5 gal bucket, easy cleanup, bob's your uncle.
Yep you can do that with your mill I choose this method and My uncle is George.
LOL
Yep, did my mill, my lathe and a hell of a lot of structural steel, no school like the old school.
Btw, if you really like that using stuff you might like a muller.
@@davidnaisuler5743 the epoxy works well not sure I plan on using it a lot i most likely will do it once more but that will be it.
Thumb nail looks like bud
Glad that it caught your eye! LOL
