John, thank you so much for your videos. I grew up in a shop. My father had a shop, but the work dried up in the 80's in this area. I was recently laid off from my IT job of 17+ years. Before that I had received my journeyman's papers as a Tool & Model Maker and worked in the field for about a total of 15 years before I changed careers to IT. I'm looking to stay out of the corporate environment now and working on getting back into a job-shop atmosphere to get reacquainted with the trade. Watching your videos has made me so excited to take the plunge to get back into the shop! Thank you SO MUCH!!! Keep up the great work!
Having worked in a pattern shop and worked with a lot of renboard it was interesting to see your tape method for gluing it down. One thing with renboard chipping is that it's easy to repair with either wood filler or by cutting the damaged section out and gluing in a new piece of renboard
I've been watching you form the beginning. You amaze me where you are at now. You sure came a long way and starting out in NYC, possibly the worst place on the planet to learn this trade. I am 65, grow up in Bridgeport Ct. At the time the best place on the planet to learn this trade. I wanted to learn this trade by the time I am was 4. By five as was barred from hanging out in Bridgeport Machines, stupid bean counters. People that wear suits just piss me off. I think at some point you will find Tomach is holding you back. You I have no dough will want to play with the big boys. Big boys need big boys toys. Keep amazing me and when you go public let me know. I'll buy some of that. In a heart beat. Sean
The main problem with that vacuum sucker seemed to be it was only sucking on a small part of one side. How about getting a 4" or 5" round Tupperware bowl, cut a hold in the bottom to fit the spindle nose and another hole in the bottom corner to fit the vacuum hose, and mount it as a hood on the spindle nose? Should catch considerably more swarf.
You need a CNC router with some good dust extraction and a nice blower for hold down. 18k spindle speed and 500 ipm would knock that thing out in a hurry.
Rambozo Clown tapered end mills would not work in this situtation because the corner radii seem uniform from top to bottom. Tapered end mills would produce a variable radius due to their conical shape.
MiggyManMike 'Tis "very high bond" masking tape, not ordinary painters tape. Or, to put it differently: it slightly amazes me that you heard him say the kind of tape he's using, but you hadn't actually understood the meaning of the words.
Hey John, been watching a lot of your videos lately. I also make molds for casting but i 3d print them. I was wondering how much a machined part like that runs with cost of stock + machining time?
Hi john I currently run a thermwood router to machine patterns for a foundry. I use Itape to hold patterns down on a table pretty amazing stuff you should check it out.
This will be the "positive" used to create a negative in the sand. Once the pattern is removed from the sand, the "negative", the void, is what gets filled when metal is poured. Check out Tubalcains many videos on foundry patterns, he explains the process well.

Lucas Imark Going out on a limb. I’d say he tape/glued it down instead of a mechanical fastener because he ended up shaving a whole inch off the top and the fastener would be in the way. Unless you were referring to after the top one inch was removed, then he still didn’t need a mechanical fastener since the new stock was exactly where he needed it and at the exact height.
After watching several of these with the tape the answer is NO or else there will be double thickness of tape where there is overlap. Just be careful putting the tape down.
The suerglue does great, but the tape may not depending on the brand. I suggest getting a few brands to try out. Make sure it is not the low adhesive type.

Nice vid, FYI cutting lots of regular (non laser) MDF will fog your mirrors prematurely as the adhesive vaporises.
Great work John it's be awesome if there were a follow up video through to the actual casting and seeing the finished part.
I'd love to see this.

Nice use of that tapping head to put some pressure while the glue dries!

I'm diggin' these casting patterns. I enjoy learning the 3D machining features whenever you do them

Nice Norseman knife!
4:14 You got some splash coming off the HAAS in the back.
The hot tip for pattern draft are tapered end mills. Perfect surface finish and way faster than all those step downs.
Rambozo Clown tapered end mills would not work in this situtation because the corner radii seem uniform from top to bottom. Tapered end mills would produce a variable radius due to their conical shape.
Love the subtle Grimsmo ad in there.
Id strongly suggest some tapered endmill cutters 1deg. You can save a LOT on time and get a precise fihish.
The foundry I work at we use tapered endmills that match draft angle. Not sure if buying them is feasible on a small scale project like this.
Nice job! That turned out great.
oh yea, more superglue! works awesome!
Just wondering why you ordered such a thick piece of material. Isn't that expensive?
Great video. Would love to see you use it for casting!
I'm slightly amazed that you've got the 3d printer now but hadn't come across blue painters tape! :D

Thank you for all the priceless tips! I Like your videos very much. By the way: Which editing Software do you use? Best Regards, Damian

Beautiful part!
Why don't you use something like a renishaw probe to set the origin for your workpiece?

Why did you use a bull nose end mill for the drafted wall finishing instead of a ball end mill?
Anything is metal additive manufacturing worth exploring? Or too expensive?
Compression head for added pressure- genius.
Thank you for these videos
what is the type of 3M tape you are using, i cannot find it on the net?
How long from start to finish did it take to make that?
Awesome, but how would you use this for casting? Bury it in sand and pour metal into that?
Is this solid polyurethane or higher density rigid PU foam?

Reshape BM70 is the material.
Thanks!
Cool cast iron surface plates to go with Tom Liptons mini granite ones! :-)
You know a Biax that size would probably actually sell well, it would be great on dovetails!
Might it be called a Smiax? 😂
Why not just cut down into the sacrificial plate instead of switching back to a square edge tool? You could have just made the bottom height -0.035".
Man you need to re calibrate that Haimer. It should be at 0 when in rest position. I have the directions from them on how to do it.
What’s this material called? Foam?
@4:11 Why does it never go in the first time?
Why did you glue it and didn’t simply drill holes in the block and screw it directly to the table?

Anyone know why there was the square pattern laser cut into the face of the mdf?
Which 3M tape and superglue? Could you please share manufacturers part numbers? Thanks in advance!!!
He says they found some new tape type (3M VHB) and superglue that works better.
Where du see green #2060 in this video? Here (@1:22) ruclips.net/video/w2hzIM2rijQ/видео.html he says "3M Very High Bond masking tape".
Great video that material is excellent to machine. thank you for sharing. Matt C
Need a dust boot, a surround for the bit...only caveat, it will block the view of the cutting (unless you make it clear)
It also would potentially impact the work piece unlike a CNC router. Need to keep that thing open on all sides.
What material did you make the casting pattern from?
wood hacker Reshape BM70
@@unknownapprentice625 Typo, it's Renshape

Do you overlap the tape?
After watching several of these with the tape the answer is NO or else there will be double thickness of tape where there is overlap. Just be careful putting the tape down.
how does the superglue do with flood coolant?
The suerglue does great, but the tape may not depending on the brand. I suggest getting a few brands to try out. Make sure it is not the low adhesive type.
Tangobaldy enjoys these videos.
Красота!
It is a foundry pattern which is used to make a casting, it is not a casting pattern. Nice job though.
The whole world is drafted
Success!
Nice Norseman knife. I would have one but honestly, my money can be put to better uses.

Evan Parent it's pretty hard to justify a 1000$ pocket knife. Im sure grimsmo have saunders a discount.
It was a gift.
Your vacuum did literally nothing
