Thank you for dropping by. I really enjoy your channel, amazing work with such a small mill and lathe. In the mean time, I have acquired a cast iron balancing jig that I will do a follow up on.

Those are chunks of tool steel that were machined to shape.

Wasn’t an issue at all. It may be due to the small size. Larger items would benefit from pre-heat however if you read the literature from some nickel manufacturers they say no pre-heat necessarily.

Great idea. I wasn’t able to get it all off with the brush, very stubborn.

@@garysgarage101 Most welders use wire brush wheels when the power is available :) Also, bring your heat wayyy back and you wont blow through your metal with the arc. That cast Iron is extremely conductive and soft.

@@ww6609 That’s great to know. I tried welding a chunk of cast iron to mild steel yesterday and found increasing the heat (to 120A on 1/8 electrode) was worse. Went back down to 100A, was more manageable but found the bead to be quite tall.

@@garysgarage101 At that point you are cross welding and you would want to use Tungsten Inert Gas welding over SMAW. TiG is really fun and was originally made for cross welding aluminum and titanium for the SR71 Blackbird's leading edge. Supersonic is hot enough to melt aluminum. I'd say practice and mess around with each setting individually on extra material with your SMAW machine so you can learn how your machine behaves. Each one has its own soul. btw, striking the flux electrode can be easier to start (DO NOT HAVE IT IN THE MACHINE WHEN YOU DO THIS!!!) if you tap the tip with your welders hammer or a sharp surface to expose the smallest of the filler metal for an easier start.

I believe this is what I sourced on ebay: Item info AC-DC 5V 3A 15W Power Supply Buck Converter Step Down Module High Quality USA

TTL standard. Very happy with the setup.

Humm, no I didn’t. I like the idea and will look into it. Thanks for the suggestion and stopping by.

@@garysgarage101there’s real.y nowhere in the crack to mount it. I’ve been looking to do one in mine as well. The oil connector, the vertical stops, etc. all get in the way. I’ve been thinking of using standoff (sturdy ones!) to move it back, but I haven’t decided. I assume you’re using a 1 micron scale as the standard 5 micron scales just measure to about 3.5 tenths, though it may look as though they’re reading by tenths. I used 1 micron scales on my lathe and liked the consistency so much I changed the one on my mill to that as well. The readout goes to 0.00000, so it can actually give the right numbers.

@@melgross yes, 1 micron scale.

That's correct. Most chucks have a recess on the back for that purpose. I wasnt so concerned with doing it on this one BC the chuck was a 4 jaw do doesn't matter where it sits.

@@garysgarage101Ok, that makes sense!

Biax is adjustable up to 20mm I believe, however the typical stroke length set is 10mm which is why I chose that.

Sure. The purpose of THIS build series was to make a tool that would aid in topics you mention. There are many videos on YT that cover scraping, including 1 on mine. I said in the video that the table saw was a surface I didn’t care about for testing the tool. Hope that helps clarify things for you. Thanks for stopping by.

@@garysgarage101Thanks for your explanation. I like to watch old (as old as I am;) machines being restored or just still being used. I’m curious why you don’t care for that table saw surface. Are you going to restore it sometime? Again I’m just curious. Greetings from the Netherlands. PS Ah at the end you mention that you’re going to do the finishing work by hand! (I would love to see a video of that to but I know that producing a video takes a lot of time so it’s not a request;)

I guess what I meant was that I don’t care about keeping the original appearance of the table saw surface. I quite like the scrapped appearance though. It’s very slippery and shiny in person.

@@garysgarage101 Thanks! 👍

@@garysgarage101 What I would have liked to know is how much material was removed and is it comparable to hand scrapping. I kind of thought that you just like the finished look of the scrape pattern by what you had said. Ok thumbs up.

Those are cooling fins, not vents.

Go back to time stamp 3:15 where you can clearly see the vents are clear from the strap.

After spending 40 years seeing what real scrapers can do by hand and the dressing up the surface with an electric scraper this is quite frankly sad Sorry

If I had to guess I’d say 200 rpm. Lapping Typically run slow. Thanks for dropping in.

Reciprocating? 🙄

Never thought of that. Great tip.

@@garysgarage101 l run a Harig and Okie's most of the time. Their arbors are different from what you're running. I'm a retired Meadville PA Tool and Die maker. I was in the game for 42 years.

That mandrel came with the surface grinder. Best way to measure the taper is to mount the hub in the lathe and measure that instead.

Thanks again.@@garysgarage101

Just added the links in the description.

Outstanding, Thank you.@@garysgarage101

Yes, I’ll follow up with some scraping for sure. It was a fun project.

The head can go all the way up and down without running into anything. I had to pay close attention to this before drilling holes but it worked great. Welcome to the channel, we love Poland.

@@garysgarage101 thx for answer. I also asked for dust collector addon? Can you answer?

Dust collector is simple sheet metal cut with a plasma cutter. I don't have files, sorry.

@@garysgarage101 thx! <3

That’s excellent advice. I’ve seen that done and it makes total sense.

Grinding the first face in a vice eliminates the magnetic chuck pulling out any bow from heat treatment. If the first face was ground flat directly on the chuck, once released the bow would return.
