Magnetic V-Block

I picked up a magnetic V-blockand have found it to be a valuable addition to my tools. I notice that on the side it has what appears to be a lubrication hole that is sealed by a small ball bearing. I googled v-block maintenance and found absolutely nothing about lubricating the interior components. ...

Re: Drilling Hole In Sandblast Cabinet For Bulkhead Adapter

I have a small cheapo HF blast cabinet. I wanted to bead blast a rifle barrel and action. Obviously, the cabinet was too small. I knew an electrician that had the punch equipment. He punched a 4" hole in the side of my cabinet that allowed me to do the gun 1/2 at a time. In case you are wondering ho...

Re: Machining Cylinders - How to Do?

I lap the cylinders with a DIY lap using "Timesaver" lapping compound. Cast Iron is usually pretty easy to bore. A sharp and rigid boring bar will give good results and require a minimum of lapping to get a good surface. I use O-rings in lieu of packing or rings. Ignore the manufacturers recommendat...

Re: Machining Cylinders - How to Do?

Marty, I just finished two cylinder castings for a Stuart Double 10. Their instructions were to center the exterior of the casting to run as true as possible and not to worry about the cast in bore as there should be enough "meat" on the casting to allow for the cast bore to be a bit off center. The...

Re: Propane oriface size

Hi, I hesitate to join in on this thread as my attempt to gas fire my 3-1/2 scale Rob Roy have for the most part been unsuccessful. My problem is that I think I am trying to put 10# of stuff in a 5# sack. The firebox is 2"x3-9/32". I am guessing I need approximately 16,000 btu. I am close, but not y...

Re: Question on 3.5" Rob Roy drawings

WJH, I would strongly suggest you google "Errors on Rob Roy Drawings". There quite a few listed as I found out during my construction of the 3-1/2" Rob Roy. Good Luck, Rick

Re: Are Engineers the Most Obnoxious People in the Universe?

I gotta comment on this since I hold some "Engineering" credentials! Engineers are schooled {taught} facts, theory and so forth. Wrench guys know how to take it apart, fix it, make it better and then put it back together. A good engineer talks to the wrench guy and ask. What do you think? You need ...
