Does the drill press have four step pulleys to adjust the spindle speed, like an old South Bend lathe? If so, I would set up the driver so the final spindle was turning about 60 rpm for large bits, up to 220 or so for small bits. The 'machinerys handbook' has formulii for driving and driven pulley diameters.

The drawings look great! What phone model and what app?

is it a clamp for holding the patch on an inner tube for flat tire repair?

I think I read somewhere that burning brake cleaner makes phosgene gas, which will kill you dead. Can anybody confirm this?

A buddy and I each built one here, but we got the heads from John, and we hired Keane to come down and help with the final touches.

The ramp is 6 inches total, 4 inches straight, 1 inch taper each end.

So many great ideas have been 'killed by committee'. We gotta keep everything before 1148 AD...I give time to the historic museum in Weaverville, California. It's a 1849 gold rush era place. The museum, in a bold strike of common sense, asked the folks volunteering as instructors what should happen to get the community involved. They realize most stuff can be made with charcoal used in last nights campfire. What they do now, is "get folks started". They have a ying-ang hammer out back, I donate tooling that has been TIG welded, the chairman hunts the steel pile at the dump for resources. The bottom line is, for some reason, the whole thing works. There's zero trade secrets, we all give face time while demonstrating to anyone who walks up, the local motels fill up when we invade for the annual hammer-in, and by Sunday there's no more Scotch in town. I've been to a lot of doings on the west coast USA, and this little museum wins, hands down. It's a paradigm shift. Make stuff easy for folks to attend, and everybody wins. Everybody in your town knows what went on at the period your venue is supposed to represent. Embrace that, make the price cheap, and then,,, go behind the façade, and 'get the community started'.

Reading, is your class in Weaverville? if so, I donated the striking blocks you speak of to the museum, and I'm glad they are getting worked!

Very nice. What size air cylinder are you using, and how many Blows/minute are you getting? 3/4 inch hoses are a good idea, but did you hotrod the cylinder to accept them, over the old 1/2" ports? These Kinyon hammers keep getting better, with every individual mind that attacks them. I love the creativity...

Dry rub pork ribs over smoke, and a good single malt. Hey, don't wait 'till your birthday, any Wednesday will do.

I'm glad the MSDS sheet was posted for spikes. Now I know that if I poke a spike in my eye, to rinse with plenty of water..

Howdy. I'm in Klamath Falls, stop by if you find yourself needing a travel stop on the way to Reno...

Forgot where I heard this. Craft is stuff that get's used (weathervane, hinges, fire tools). Art is stuff you need to occasionally run a dustcloth over. I do both, and don't hold a grudge either way.

I was walking around old town San Diego and happened across an historic working blacksmith shop. As I approached, The smith pumped the bellows a couple times, and went to work on the anvil. I noticed the coke fire kept bubbling, and he ain't pumped the bellows in a minute or so. He would have fooled a normal citizen, but after me asking, he threw down and admitted he had an electric blower underneath, and just pumped the bellows for show. It all came across quite well, I didn't call foul..

I've been goofing with this lately. ABANA education has a beveled, blown over leaf scroll as part of the grille part of the learning curriculum. After generating the triangular bevel, you can skew off the anvil bick with well placed soft blows and generate the curve you need without hurting the bevel. It's really frustrating, which is most likely why it's an educational element. If you can find the COSIRA book 'wrought ironwork', they sort of cover it, Hammers Blow had an article last summer covering it also.

See you there, Ian. We'll shove an extra bottle in the knapsack so you don't get dehydrated!

That is really, really cool! Keep being creative, please. Also, put a dollar bill or a pop can next to it so we can visualize scale of the project...

Thanks for the heads up.. I haven't dug into the guts on mine yet, any chance that the O-rings are standard, readily available at the auto parts store sizes?

Nice machine. It's hard to tell from the picture, but it might benefit from a sheetmetal guard to keep chips out of the electric guts.

That's very nice work, amigo.

If you're so inclined, there's math-e-matics to help you plan your finish drifted hole. I use flat bottom slot punches, and as Mr. Turley said, there is some draft when punching . I can minimize that by careful layout, and punching in from both sides. I look at the final hole diameter, say 5/8 inch, or, .625 inch. The circumference of that hole is pi x d , or roughly 3 x .625. That equals 1.875, or 1-7/8 circumference. A 1/8 thick slot punch works good for this size hole. If I round the edges off the punch, I have a flat bottom slot punch with rounded edges. (===) Each edge is half a circle. Pi x d for a 1/8 (.125) circle is 3/8 (.375). So take your 1-7/8 original circumference and subtract 3/8. You come up with 1-1/2 left over. since the punch has 2 long edges, divide 1-1/2 by two, and end up with a 3/4 inch slot punch with radiused ends. when you put the drift thru, the slot will collapse and expand to the size of the 5/8 finished hole.

FE, if your drive sheave quest comes up dry, I'm sure we could make you one in a day if you drive north a bit.

I'm with Eric, after a while I developed a whip at the end of my swing, sort of a loose gripped, wrist activated, almost throwing the hammer down, than loosely catching it on the way back up, move. I just realized this is real hard to put into words...

I've had the pleasure of attending a couple hammer-ins when Eric brought out the guitar and fiddle. He's got a heart as big as the whole outdoors. Our family sends happy thoughts.
