I've always felt they were very high-quality punches. I've got quite a few of them, but they're old, and I used to use them to punch holes in steel car bumpers(!) to mount CB antennas and trailer electrical connectors, so unfortunately most of them have become dull. I'm wondering if a DIY'er...

On a reciprocating air compressor, since you can't install the pistons from the top of the cylinders because the connecting rod bolts face upward (i.e., you have to install the rod bolts, pistons and rings first and then lower the cylinders over the pistons) and therefore can't use a normal ring...

I've been doing quite a bit of outdoor sandblasting of large car parst with an old Tip portable blaster that has a 90-lb. pot, and using 30-mesh sand as the abrasive medium. My compressor has 10 hp. and is connected to an 80-gallon air tank. With the 30-mesh, I find that a 1/8" blasting tip is...

So far the best deal that I have found on a drill bit set for measuring the jet size on Thermoquads is the Harbor Freight cheapie carbon steel 115-piece drill bit set for $40.00. The jets I want to measure are around .09" - .10", and the set contains 5 or 6 drill bits in this range. I think...

Despite having used it a lot, and having watched a lot of videos, I'm still not clear on how to adjust the choke valve and the media valve on my pot pressure blaster. When adjusting the choke valve, what exactly are we trying to achieve? And when adjusting the media valve, same question...

I have been doing quite a bit of sandblasting, and have become impatient with needing to let my present compressor re-charge too often, so I'm thinking of upgrading. But all the compressors I really want are 220 volt 3-phase, while I have only single-phase 220 in my shop. I do have a spare 225...

I had a lot of trouble removing the rear wheels from the old, rusty square taper rear axles on my '22 Dodge Bros. tourer. I looked everywhere for a Dodge Bros. hub puller, but couldn't find one. The center of the hub is threaded 2-7/16" x 16 TPI. I finally heard about George McMurtry* and...

My Central Machinery 12-speed drill press, which is about 2 months old, developed some wobble in the spindle and I'm not clear on how to adjust it out. Maybe tighten up the spring on the left side of the spindle body (part nos. 57 & 58)? Or adjust something in the spindle and spindle sleeve...

I'd like to drill and tap several of these holes. I've got my 25/64" drill bit for the tap, but I don't know what kind of tap to buy. Some of the types I've seen are "chip-free thread-forming", "spiral flute", "spiral point" and "straight flute". I was thinking of buying the "spiral flute"...

I hope I don't bore you guys to tears with this, but I felt the need to vent. There are quite a few youtube videos where people claim to have constructed a giant air compressor by simply connecting together the output lines of two small compressors. That is clearly not going to work correctly...

When you buy a lift, the seller bundles all the heavy parts up together for shipment by attaching them with 3/4" hardware to some really Hefty & Brawny welded-up steel end supports, which I will call the "LBES" for short (see attached picture). These things are way too nice to throw away. I...

For sandblasting I use an old TIP pressure blaster fed by a 12-hp, 25 SCFM compressor. I have always been pretty happy with this setup because it will blast parts about as fast as you would want to blast them. I use regular sand for my abrasive media; I blast outdoors; and I do not re-use the...

I've been looking for a dial-back type timing light, but all I've been able to find for a reasonable price are Chinois pieces of junque. Can anybody please point me to a dial-back light of good quality that gives "bang for the buck"? Thanks a lot.

I drilled sixteen 3/4"-diameter holes 5" deep into the concrete floor of my shop in order to bolt down my 4-post lift. (That is way overkill, I know, but it makes me feel good.) First, because I knew nothing about concrete drilling, I tried a Makita hammer drill model HP2050 that uses...

Luckily I got a good friend to help me. It was a lot of work, and very tiring to install.

1. Will you guys who have been around forever please take pity on me and tell me how you used to use an old-fashioned, free-standing oscilloscope to examine the spark on an engine? What kind of attenuator would you use, and what sweep rate? 2. What do you think of those "paint-can" smoke...

I have decided to buy a Direct Lift 4-post lift because I've purchased one of their rotisseries, found the quality to be top-notch, and IMHO Direct Lift provides a very good bang for the buck. What lifting capacity would I need in a 4-post to lift a B-200 camper van or a D-300 dually? Thanks...

I want to lift the body off the frame of my '22 Dodge Bros. tourer in order to do a proper restoration. I plan to jack the body up off the frame, put two 2x4s under it, and attach 4 cables to the ends of the 2x4s, running the cables over pulleys attached to lift points in my ceiling. Should I...

I'd like to buy a 0-2500 psi gauge in order to test tractor hydraulic pumps. I see a lot of hydraulic pressure gauges listed on Amazon.com, but I want to be sure to get something of decent quality. Also, I'm kind of a cheapskate, so I don't want to spend more than necessary. Anybody know of a...

I soak the part in naptha in my parts washer and then scrape the top, softened layer of the gasket, which comes off easily, with a single-edge razor blade scraper; but when the going gets tough (when I reach hard gasket material), I drop it back in the naptha again for a few hours. Every time...

I just thought I'd run this past you guys, since not too many people have ever heard of this. Back in the early '70s I got heavily into bicycling, and later I took a class on how to build bicycle frames. You need to avoid burning such thin tubes when brazing them, but at the same time you need...

Can't use a regular drywall lift for my shop ceiling because it is too high, so I am going to install it from a 2-level scaffold instead. The only problem is, I'm stumped about how to lift it up onto the scaffold. Would any of you guys have any bright ideas about that? Thanks very much.

I want to repair some small Mopar parts by silver soldering them back together where they broke. I have no problem melting the silver solder on the work and getting it to flow (using white brazing flux) when using an oxy-acetylene torch with the smallest tip I've got ("00") and the flame...

I just bought a 40-gallon capacity parts washer which requires 20 gallons of cleaning solvent. What kind of solvent or cleaning agent would you guys recommend, and where's the best place to buy it? Thanks a lot.

I've got four Mopars and a Porsche, and I refuse to let any of them sit outside in the rain, so I keep them in my shop during the winter. Since they completely fill the shop, I can't work on any other big projects when the cars are inside. So I am building a carport with a "shed" or "lean to"...
