Greetings Everyone, Today I started the fab of a belt guard. I had several sheets of .072 steel to work with. I also had a couple pieces of solid core door to use as a hammering fixture.
So I laid out my fixture on the wood. Fixture layout by Glen Ray, on Flickr
Then I cut the fixture out, layed it on the sheet metal and drew a line about an inch larger all the way around the fixture. I cut the front piece out using a jig saw with a metal cutting blade. Then I sandwiched the front piece between the two halves of the fixture and secured the whole thing with a couple bolts. Ready to start by Glen Ray, on Flickr
Then I started hammering the sheet metal. It took about an hour to get to a point where I was ready to remove the piece from the fixture. Hammering started by Glen Ray, on Flickr

After I removed it from the fixture I trimmed up the flanged edge and I began working the flange with a hammer and a 20 lb piece of steel. It took about another hour to get the flange straight enough to work well. Front trimmed and hammered straight by Glen Ray, on Flickr
Then I cut three 3" wide pieces to use for the side walls of the guard. I began forming the first piece and got it to a place I believe is ready to pop rivet to the front piece. Front and first side wall by Glen Ray, on Flickr
I'll continue to work on it and I'll update this post as I go.

surpluscenter has lots of neat stuff, but for belts, this place has a better selection & prices. Quick shipping too. www.vbeltsupply.com/Wow! yea! $2 cheaper, for an A57 belt, than the great price I paid at Surplus Center. I put them in my favorites. Thanks for the tip.

I saw they have a free catalog. It sounds like I should get one.

This is an old saw that I got from an estate. Rockoonz and I pulled it out of a mud puddle. I had 6" of water in it, The carriage was frozen and it was in pretty bad shape. I got the carriage cleaned up. I have cleaned and painted it. I replaced the drive screw bearings and the spindle bearings. The motor is good. I am now attempting to make a belt guard for it. Here's a link to another forum, where I have pictures and some explanations. lapidaryforum.net/group/index.php?topic=2826.0

www.surpluscenter.com/
I found this source yesterday. They have a bit of everything and then some. I just ordered two 6" wheels, a 4-1/4" x 5/8 pulley and a 4L590 V-belt. The total for the products was $27.75 and $12.08 S&H for a grand total of $39.83.
My saw is almost built. My next project is my Highland Park Cabber w/ 10" trim saw. I'm pretty certain I will be buying bearings from these guys.
It's worth checking out.
Glen

I looks like I jumped the gun a bit. My saw was not all the way together. After I finished assembly I checked and I was out .020" in 17". YUK. I added a .0045" strip of aluminum tape to one side of my spindle mount and WALAH!!! Less than .001" across 18". YEA! That eliminates that concern!

Most old equipment will have rust issues. I have been reading many suggestions ranging from PB Blaster and WD-40 to Acetone/ATF mixtures. WD-40 displaces water and helps loosen things up but does not dissolve rust. PB is a good penetrating oil but also doesn't dissolve rust. Acetone/ATF mixtures ? well I haven't tried it but ATF is really high detergent and acetone would certainly help it penetrate. I needed to clean the rust from the slip clutch parts on the 20" saw I'm restoring. I soaked the rusty parts in distilled vinegar, overnight, and brushed away the rust. Ever the chain links became freed up. After the soaking and brushing, I hosed them off and soaked them in WD-40 overnight. I could spend more time and get them cleaner, but I'm happy with these results. Rust by Glen Ray, on Flickr

OK so I have a Flickr account. It took 20 minutes to figure out how to upload a picture into it. Now what? Are there any SIMPLE step by step instructions to help get through the flickr maze? All I want to do is add a picture to a post. I really don't want to become a Flickr junkie.
Any help would be appreciated. Thanks Glen

Greetings
I'm trying to upload a 100K Jpeg file and the forum says I'm exceeding the size limit of 1Mb. What's wrong here?

Greetings All, I'm in the process of restoring an old 20" saw. I have replaced the spindle bearings and took some measurements. I think I'm OK but this is my first 20" saw so I'm not certain. I would appreciate your opinion.
I measured blade run out. 1-1/2" from the edge, I got a total of .016" of run out.
I measured the blade/vise carriage alignment and found that across about 16" I am .004" out of alignment.
I know the closer the better but will I see any real gain in cut quality if I improving that .004" misalignment?
Thanks Glen

Getta Grip , I ran a 12"dia.x12"long sched. 40 PVC barrel quite steadily for 12 years before it got thin and cracked; start runs with 16 grit. They are durable. 12 x 12? So that runs about 50 pounds of rock? (figuring gravel about 90 pounds per cubic foot and 3/4 full). That's a bunch of rocks!

So, You don't need anything inside the barrel to assure tumbling? That makes it easier 8^)

That would be about 18 pounds of rock. Does that sound right? OOPS! That would be closer to 45 pounds. Yikes! That's a lot of rock!

Shotgunner.... PVC? OK I have not been into rocks for 50 or so years. I may need a bit of an education. I am an industrial mechanic and I tend to over design things. I have a couple questions. Isn't PVC vulnerable to the abrasives used to tumble? How often do you replace the barrel? PVC is smooth inside. Do you do anything to the inside to assist the material in tumbling?
jamesp.... 3/4 full? Really? Wow! OK so if I'm using a 14" barrel(tire)that is 7" deep, I would lay it down with one side plugged off, and put about 5" of rock and grit in it? Install the other plug and put it on the rollers? That would be about 18 pounds of rock. Does that sound right?
HMMM.. With my design I could seal the holes fairly easily. I'm more concerned about the abrasion eating the tire up. I have worked on industrial vibe units. They use a polyurethane lining that has a durometer rating of 90 - 95. I can buy the material in sheets and glue a lining in, but I would rather find a liquid I could apply to the inside.

I have a plan to use a tire for a barrel. After reading a bit, I found the tires do in fact wear out. Has anyone done any testing of rubber coatings to resist abrasion?
My plan sets a tire in a hexagon frame to provide an aggressive tumble. The frame is set between two 15" wooden disks that will ride on the rollers.
I won't want to replace the tire because the frame is sized for that specific tire.
If you have done any experimenting with abrasion resistant coatings, I would appreciate any information you could share.
Thanks Glen

Greetings Everyone, This is my first post to the "Home made Equipment" forum.
I am making plans to build a tumbler. I am consideri9ng using a golf cart wheel for a barrel.
I am guessing this is not a new idea and some one probably has some experience with this.
Here's my first question; How does the inside of a tire hold up to the abrasive pounding over time.
If the abrasive tears up the tire, has anyone attempted coating the inside of the tire with liquid Urethane products?
Thanks Glen
