Re: Drill Doctor DD750X - Last Ditch

What drill bits are you trying to sharpen? I have the DD750X, bought it figuring it would be easier/quicker than hand grinding. It is a total disaster trying to sharpen a HF cobalt steel bit set, which are 135deg I believe. It fails to properly split point and crashes into the folowing lead edge whe...

Re: Building a trailer coupler?

Eh... thanks... Im slowly teaching myself to weld. Sometimes it looks like I know what I am doing... Sometimes I completely forget what I am doing, grind out and repeat... This was all done with stick, 1/8" 7018 mostly. The major connections have a 6010 root with 2-3 passes of 7018 on top. It's my s...

Re: Building a trailer coupler?

Yeah, I have a standard 2" coupler that attaches to a 2-1/2" channel/tube already, they are pretty cheap. The problem is that there really isn't anywhere to directly attach it and I'd rather not cludge it on. The mast is a piece of 4x4x1/4" tube about 5' long. The end of it has 3 pieces of 1/2" plat...

Building a trailer coupler?

Has anyone ever built a trailer coupler? Any suggestions for a design to go over a 2" ball? I am rebuilding a towable engine hoist. Originally built for the rental industry I think, but I havn't been able to find a manufacturer or model number anywhere. It is built with all heavy 1/4" wall steel tub...

Re: What type of Collet is this?

Looks similar enough. I prefer Tools-n-Gizmos collet list, seems to be the most complete I've found.

Re: Materials Sourcing

Besides stopping by the junkyard to browse their good set aside tube/plate/bar, my favorite place has become Industrial Metal Supply (IMS). They have large showrooms with lots of precuts, "hobby-size" in various sizes, and assorted random cutoffs at reasonable prices (in addition to the standard 20/...

Re: Casting question

I have used wood, or rather wood-charcoal, to melt all of my aluminum machining/scrap. I haven't directly sand cast, but poured ingots for later use. I started by making charcoal with old wood (for grilling too), mostly 2x scrap, cut into 4-8in lengths. Built a good roaring fire in an old charcoal g...

Re: Rockwell Mill: Where to find?

Roy, As you found... for sub-$2000 mills i good shape, you do have to be on the ball, but they are out there. Here is another $1800 one that just popped up: http://milwaukee.craigslist.org/tls/3601348974.html OK, so that's a wee bit of a road trip, but it's OK. Embrace the lunacy of your new hobby w...

Re: Rockwell Mill: Where to find?

No matter what the mill, you can always find overpriced ones.... Those are the easy ones to find. The decently priced Rockwells go quickly as there are few solid 3/4 size models around. Looking around, there was one in Philidelphia for $1150 and another in Jersey for $1000, but both look to be gone ...

Re: Typical face mill tolerances?

*Note: I fixed the above... I wasn;t complaining about a 1 ten-thousands difference between insert settings, but rather a 1 to 1-1/2 thousands between high and low teeth. This is a brand new Glacern R8-FM45-250 with the recommended SEHW43 inserts, also from Glacern. I was asking as I knew Glacern wa...

Re: Source for measuring pins?

Ah ha! Drill blanks and reamer blanks... I think that's the ticket. I had searched all different combinations "pin gauge", "measuring pins", "ground rod", etc. Kept coming up with long stock or go/no-go pins, or people saying to use "measuring pins" to measure dovetails... Is there any difference be...

Typical face mill tolerances?

I just received my first face mill last week, in my eternal quest to collect tooling of all sorts, a brand new Glacern 2.5" FM45-R8 I've been eyeing for a couple years but didn't quite have the conviction to jump on until now. Oh boy is it fun, turning what was a 6-7 pass job with a 3/8" endmill int...
