POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

This post fits under several categories, Blunders, What did you buy today, and probably a few others. Months ago, I posted buying the BT pallet jack of CL. The seller had cleaned it up reasonably and demonstrated it. It looked used but in good condition, so I bought it for his asking price of $150. Used it to move a few things around and the jacking wasn't smooth and the load wheels didn't rise in unison, but it worked. The next day, there was a pool of hydraulic oil under the jack. Down the rabbit hole, I went. The rebuild took several months because of numerous interruptions and ordering parts, then more parts, and more and more. The rebuild kit was $90, and a week later I began disassembly.

It was missing a few roll pins and push-in zerk fittings. That was another $30. These prices include shipping which was nearly as much, and a few times shipping was vastly greater than the part. And of course, I couldn't get all the required parts in the first one or two orders. I think I had to make 5 orders, with shipping taking 4-5 days each time.

As I was installing the ram, I decided it would be easier to flip the frame over. That's when I knew I had much more than a pump rebuilt. One of the pushrods was bent to hell. That was why it didn't jack evenly. This also allowed me to inspect the load wheels. They were completely trashed. I was kicking myself I didn't pay much closer attention when I bought the jack, but I never would have thought to tip it to inspect the undercarriage. This is also my first experience with a pallet jack, having never owned or operated one.

Disassembling the load wheel assemblies was a chore. I was able to remove it from the pushrod without much trouble, but the axels refused to budge. They were no match for my HF 20-ton press. Installing was a breeze in didn't require the press.

New entry/exit and load wheels set me back another $80, and I spent another $30 or so on new snap rings. I took the pushrod to the press. I'm glad I have air-over-hydraulic. It took 15-20 minutes to get it pretty well. It the pushrod on the right. The new wheels are installed too.

I would have finished this last weekend, but I forgot about a worn-out snap ring. It's included in the prices I mentioned. This purchase was particularly painful. The clip cost 30 cents, 4 cents tax, and $13 shipping!

Today, I finished getting everything back together and it works perfectly - smooth and no leaks. I'm into this jack for about $350, plus an HF Icon snap ring plier kit and a set of Grace roll pin punches. I posted those purchases months ago when I bought them. :grin:
 
I'm in the process of building a portable workbench 30"x8' from materials I have on hand. Had some cast iron wheels from an old granary hand truck that have been sitting on a shelf in the loft for 40yrs. I'm guessing the castings are probably a hundred yrs old, and were a little out of whack in every direction. Cleaned up all the flash, and bead blasted them. Re-centered/bored the hubs on the mill, loving the new power feed on the Y-axis. Then turned the hubs, edges, and rolling surfaces on the Atlas, and de-burred all the sharp edges. Think I will paint the centers satin black and plasti-clear the the wheel faces and edges. Cheers, Mike

@Gaffer

I'm shocked by the shipping costs you describe. Highland, CA is not exactly the back of beyond. I would think that many small pins and retaining rings could be found at a local supplier. A well stocked ACE Hardware even.

McMaster-Carr shipping would be about 1/2 (and fast) on that retaining ring.

Did you buy all your parts from the same place? Please reveal the business name.

At least you now have intimate knowledge of the PJ and it's condition.

I bought everything from https://www.genericparts.com/
Josh was very helpful and spent a fair amount of time with me. I didn’t mind spending a few extra dollars versus time spent chasing parts. Had I had my act better together, I’d have saved myself time and money. I’m disappointed with my carelessness, but I know I have a pallet jack that will far outlive me. Lesson learned.
 
I upgraded my relatively new Delta 8" Bench Grinder with an 80 grit Aluminum Oxide wheel and an 8" "SCOTTCHEN" deburring wheel"

Yes, I know that there is no guard on the deburring wheel, but I haven't yet seen anyone who uses a guard when deburring. I am mindful of the potential for brushing against the deburring wheel when grinding on the right side, so am working on an easily removable guard that would be in place whenever not deburring. In the meantime, I'll just leave the deburring wheel off when not in use; to that end, I also (probably) created a warranty issue by filing flats on the left shaft to make it easier to change wheels:

The flats are located on the rough-turned portion of the shaft so they don't interfere with the 5/8" mounting portion of the shaft.

I'm also going to fit washers on the ends of the housing to minimize grit entering the bearing areas. More to come.
You'll be fine without a guard most likely, lots of buffing and deburing applications don't use one.

Hardly newsworthy but one of those times when you’re happy you have the tools that you do. This is the take up arm off an Elna overlocker. Why someone felt they needed to saw the top off I’ll never know but with a bit of scrap from an old filing cabinet and some braze it should be good to go again.

Thanks for looking!
 
Finally replaced the SHCS's on the inexpensive DTI Holder I got a while ago:

For those not familiar with Shear-Loc press-on knobs, they come in a range of styles in both metric & imperial sizes (see attached PDF), designed for pressing onto the heads of socket head cap screws (SHCS); although Shear-Loc doesn't state this, I don't recommend SHCS's that have smooth heads – less surface to grab the knob.

And before anyone asks, the hardened press tooling plate was purchased off eBay 9 years ago; I just checked and the Seller doesn't have any currently listed and I find them (searched original description "Hardened Arbor Press Tool" & "Tooling Block").
