Thanks for the clarification on the prep portion. That is one of the best ways I have heard to describe it. One you get the feel down, it is easy to pick up on the drag of the brush once the oxide is removed. The saw is a Femi 783. It is kind of an oddity in the US and I am not sure if it...

After a long delay, I finally got around to building this table. Working in a batch process, I set up my mitering bandsaw and made quick work of 2 sticks of 2x2x0.125 aluminum square tube. One thing I have notices with welding aluminum, is that the end prep of the joints seems to be more...

Thanks for all the suggestions. Here is my newest design with some changes incorporated. I am thinking about making one half of the top either out of a tile, or checking into getting a piece of granite cut for it. It would only work out to be 20" x 22" so I don't think the cost would be too...

I actually considered the second of these options. The Ipe stock I bought is finished on all sides already as decking board. The overall width of the planks after settling is about 5.4 inches wide. Due to the Ipe being so hard and heavy to work with, not to mention expensive, I do not have...

After searching endlessly for a new set of patio furniture, I could not settle for any that I liked that was in my price range. Almost everything was not made for long term durability or lack of maintenance. Finally I settled on building my own table out of aluminum and Ipe wood. A year later...

All of the recent acr phillips bits I have purchased from Mcmaster Carr have been zephyr. They can be purchased as sets or as individual bits. They call them slip resistant rather than acr when you are looking for them. Bits from McMaster

With the mechanical assembly mostly complete and the rough electrical setup tested, it was time to start on the control panel. While the VFD has all of the controls built into it, I wanted to mount remote controls from the VFD. This would allow the small potentiometer integral to the VFD to be...

The penetrol thins the oil based paint and allows it to flow out better. This in turn allows the paint to flow and self level after it is brushed on which reduces the likelihood of seeing brush marks in it. I think the same thing can be accomplished by thinning with an appropriate solvent, but...

One of the nice features of these drill presses is the depth scale on the quill down feed. As you can see, due to the gearing of the quill, the scale is very precise, with graduations down to 1/32 of an inch. This makes stopping at a certain depth very easy, but it does not easily allow a...

With all the cleanup and painting done, the real assembly and fabrication work for the VFD mods could be started. I bought a Teco Westinghouse JNEV-101-H1 vfd and a Brooks Crompton FA6N.75-2 Motor. The VFD is rated for 1 HP max with 120v single phase in and 240 three phase output. The motor...

Thanks!

Thanks to OWWM, it was very easy to come by several versions of the manuals for this style of drill press complete with nice exploded views of the major components. I started the disassemble with the head unit of the drill press, stripping each part off to get it down to bare castings...

I agree that under some condition like trying to clamp a small part down, the production table can be a hassle with the deep coolant and shaving thought around the perimeter and large cast iron webs underneath. My reasoning for wanting a large table was to support my drill press vise. I found...

Ever since graduating from college I have been the proud owner of a free to me bench top Atlas drill press from the 40's or early 50's. I never figured out exactly what it was, but had it narrowed down to a model 62,63, or 64. I built many great projects with this drill press, routinely...

Have you double checked your motor wiring? I had this issue on a dual voltage motor for my drill press with a vfd. I thought I had the motor wired up for the vfd's 240 output but I actually had the motor wired up for 480. I played with every setting on the vfd before checking the wiring, but...

It will depend on the gas suppliers policy, but a nitrogen bottle should have a cga 580 regulator fitting which is used for argon and other inert gasses as well. So the fitting should not be an issue. This chart explains the various fittings and the approved gasses for them...

That is exactly what I would do, that way you can just use standard hoses. Here is a link to what the adapter should look like. Adapter It is an industry standard part, so if you look up AW-430 you should be able to find it several places including local welding supply houses.

I am not positive for the lincoln brand torches, but more most any dedicated gas connections on tig welders, the fitting will be a B size with 5/8 - 18 RH threads. The two lead torches we use at work are all this way so that the gas lead can be connected straight to a bottle. Here is a good...

I did not uncrew that cap, but I assume there is a spring behind it to act on the factory pressure indicator. If the stock gauge was gutted and the gauge was added there it would probably work, but I would have a hard time believing it is worth the effort.

The hose threads into the body of the inflator and can be removed, but I think the clearances would be too tight to put any sort of tee on to add a gauge. I believe the threads are 3/8 -24, straight thread. You could cut the hose and put barbed fitting on it with a gauge, but it would be a...
