You can super glue the broken pattern together and fill , thicken or reshape with wax ... you can brush flame the wax to get it to a glass finish which helps a lot when making molds.. another bonus is you can try it on with all the modifications to make sure everything fits before you make the final casting.
There is a lot more than two problems with pressure diecastings! The use of high iron bottom of the heap metal, trapped air bubbles, sonic fill velocity causing vast problems, and from the point of view of using one as a pattern, lack of adequate draft - I could go on 😊. Nice to see you posting again.... Martin PS. Do you want a 250 liter barrel of new natural sand - I have some I wish to get rid of (sadly.) Some odd shaped firebricks to go too..
There was plenty of draft except where the casting was machined but using smooth plastic makes it a little bit easier to lift the pattern. The iron content may explain why that casting did not like to be straightened. I still have plenty of sand I got from a sand pit in Cranbourne years ago so maybe some of your viewers could use it. I'll pass on the odd shaped firebricks as I have a lot from cupolas I am not sure what to do with.
High pressure usually implies large volume masses of metal, not one-offs. Bubbles are usually a condition of unexpected impurity reactions creating secondary gas emissions from source or ambient chemical reactions from inadequate analysis of raw source materials. I highly doubt you have an analysis lab to define what your byproduct impurities will be. The point is with expected materials you have predicted results not expectations of a small or backyard production facility to anticipatate a deviation from standard production materials product to another.
Good job! For a moment, I thought you were going to make a cast iron fence. I have a very similar old saw with the same problem - the fence is warped, but I'll wait for it to break, before I try to cast a new one :-)
hey there luckygen1001... This video was posted 9 minutes ago. I really appreciate all that you put up there. I am not a bot, I swear. Hope you get monetized, I didn't see any ads.
Hey mate, how do I get in touch with you? Would like to talk about high temp crucibles. You probably already posted something on that subject, but soooooo many videos……anyhow, I’m in Darwin if you want to reach out and we can discuss. Cheers
Good to see you again. Nice tips to replace broken die castings.
Why throw out a saw when it can be fixed.

I will have to try that some in the future.
Excellent save. 👍 👍
I have found those in the trash (same reason), and realized that it is just a matter of talent to put it back in service.
That is where I found this one.😃
Hallo i am glad to see new videos of you metal casting. I enjoy every of your Video 👍 the best metal casting chanel i have ever seen on youtube 👍👍👍
Thank you.😀

Martin and Lucky: any chances to meet you both in December?@@luckygen1001
Lucky, I would accomodate any of your unwanted stuff, thank you. Please ask Martin about me. Vlad@@luckygen1001

It seems from the comments that this is a common problem.
Glad to see you again. Good job recovering the saw.
Why throw out a good saw when casting a new part fixes the problem.
Good to see a casting video making something useful.
Better than pouring cup cake molds?
Nice repair. Better than new I'll wager
I tried to bend the casting after I cast it and it did not break like the die casting.
Always interesting, well explained, real and with results 👍👍
Yep that is what my channel is all about getting results, thanks for watching.
Thanks for sharing 👍
Thank you for watching.
Nice job Lucky! 👍😀
Thanks for watching.

The ads pay very little so that is why I never monetized.
@@luckygen1001So much for getting rich off of UA-cam and retiring early!
So true!@@chasbader
A nice concise video. Thanks
Thanks.
Don't feel dumb - I have exactly the same saw with exactly the same fence which I broke in exactly the same way for exactly the same reason.
I should have known better than to straighten a old die casting but it gives me a good excuse to use the furnace.
Amazing title
Thanks.
Your flask is empty. What a drag! How do you cope?
He He He.
Were have you been lve missed you
I've been here all the time.

Just use clay graphite crucibles as I use them for cast iron.
@@luckygen1001 ok, thanks mate, I’ll give them a go on a small amount. Going on the specs they aren’t rated for 1500c+.
@@stewartwoerle6351 The place where I buy them say they are not rated for cast iron but it works for about 15-20 melts.
@@luckygen1001 cheers, that should do me fine.
The original part looks super cheap, destined to fail. Your version will be practically indestructible.
I had a go bending the new casting so there was less to sand off the working face, no more broken castings.
Jesus fucking christ. You do know you alter the sound levels when you're editing?
I did warn everybody a loud noise is coming.
