Re: Jet JVM-626

R8 would be the best you could hope for. If it's not made in R8 then you won't need it. And for North America at least R8 shanked tooling is a bit cheaper than almost anything you'd find in the MT3. If you don't have one yet? I'd say getting a X axis power feed would be very high on my list even bef...

Re: Jet JVM-626

A 626 mill with the horizontal round column for tilting the head? If so then almost any 626 manual would work. Grizzly should have one online on there website for there version of the 626. These and even the Bridgeports and there clones are all a pretty simple collection of parts other than the BP t...

Re: Brass v.s. Bronze?

Then that almost confirms what it is then Harold. It's definately quite red. Given where it came out of on the saddle blocks that help guide the sticks as the buckets crowded in or out on a P&H 1900 electric shovel then it's likely work hardened real well.

Re: Buying drill bits

Depends on you exact needs Ron. For non production use I'm not a great believer in all those fancy coatings either. Sharpen it once and the coatings gone on the cutting edge. It may still help with chip evacuation though. That said I did buy a good set of fractional, numbered and letter that are TiN...

Re: Brass v.s. Bronze?

Fwiw and not information gained through actual long term testing. And it would also depend on the exact alloy as Harold mentioned of course. But from my reading Dianne the general recommendations when using bronze is to use hardened shafts for anything rotating within a bronze bearing. For something...

Re: Large lathe levelling

Have you run a turning test under actual cutting conditions? I've found even with a lathe mounted to a 1" thick steel plate and being leveled as true as possible with a very accurate level I still had to do a very small amount of tweaking to the mounting bolts to bring it in as parrallel as pos...

Re: Cannon diagram

I'd be interested to know what logic or mathematics was used to decide where to place the various reinforcing rings. It's quite likely Marv that actual logic and mathematical based facts didn't enter into most of those cast barrel designs. From my reading gun explosions due to poorly refined materi...

Re: Bolt Handle for Kimber 308

Very nicely done. I've machined just enough titanium to know it's not the easiest of materials to build what you have.

Re: Electric motor question

Shop = machining capabilitys. You could always build yourself a large enough stirling engine to run a fan and just use the heat off the wood stove to run the engine. :-)

Re: Micrometer inspect and repair

For guns and especially trigger assembleys I usualy flush them with an electrical contact cleaner whenever I seperate the stock from the action and barrel then a drop or two of gun oil. I've got a Jewel made 2 oz. trigger on one of my guns and it's real fussy about being clean and lightly oiled. Min...

Re: Micrometer inspect and repair

Well there not in the Pacific Northwest but in Illinos. Most of the Youtube guys seem to use M.R. Tool Repair and are real happy with the work and prices. Maybe yours were "re-oiled" at some point in a misguided attempt to look after them. Using the wrong oil and / or too much seems to do ...
