Mike, the fixture was made on a Bridgeport in a class I took a few years ago. Most of it is aluminum and could be scaled down, so you could make it with most any mill. I think it needs a couple of tweaks in the name of accuracy, so I started the mods last night.

Nice looking fixture Ryan. I made a few similar for when I was fabricating sand drag quad A-arms and swingarms. For a one-off I didn't do anything quite so nice, pretty crude actually just to hold things square/true. However, for a couple of my chassis that I was duplicating the suspension on I did make some nice fixtures for repeatability/continuity.

My new project. A Delta 1426 12" disc sander that I picked up for $30. I'll be doing a video series on the restore of this machine.

I kept spilling my flux when I was silver soldering so I made a holder for the bottle and brush.

Started with an old gear out of a rear end. Had to anneal it to be able to machine it. Took a lot of heat to get it up to temperature. Used an acetylene torch next time I put the darn thing in a kiln. Board it out to fit the bottle and milled a section out to hold the brush. Made the brush holder out of PVC and glued it in place. Added a cork to the brush to cap it off. Painted it with bronze paint and added rubber feet. Was going to leave it bare steel but the flux is corrosive so I painted it.

That looks great! I think I'll give you the sincerest form of flattery and imitate it. I do think I'll use an old 7.62mm cartridge for the brush holder though.

This project took much more than a day because of the items I needed. I did put it together today though.



I got a Palmgren 400 milling attachment a while ago. I couldn't really see how to attach it effectively. So I went on ebay and got a compound rest base. I drilled two holes through both the base of the attachment and the top of the base (one for each "leg" of the attachment). Then I threaded the holes and bolted the base of the attachment to the compound base. I then bolted the bottom (red) bar across the attachment legs. I installed the top bar with two bolts to hold counterbalancing weights. In the pictures I have one largish piece of flat stock clamped in there, but I can add more if necessary.



Anyway, it don't look pretty and I haven't tried it yet, but I'm fairly happy so far.

Dang why didn't I think of the brass cartridge as the brush holder. That will be much cooler. Post a picture when you do it.

My Levin slide rest needed a handle for the longitudinal feed. Knowing from history the sticker shock heart stopping prices I have received from Levin. I just went ahead and made one, actually 6 and 12 more extra bat handles (the bat handles break off). I made the handles out of 360 brass and had them nickel plated. And gave extra attention to detail. I treat the handles on machines like the jewelry on a lady. Call me weird, but I dislike plastic handles, handles that don’t turn true, handles that don’t match and not original handles (or can tell). When you grab the handle it must feel right. It’s the only connection between you and a manual machine. Enouph of my weirdness. The bat handle part was skived on a lathe. The balls were made on a Bridgeport. And the partial square hole was broached, also on the BP. The broach was made on a Sanford surface grinder. The bat handle screws onto the ball section. Everything was polished up and then taken to be nickel plated. The plating was not that reasonable. Cost me $75 for a tiny handful of parts and they were all buffed up. All they had to do was plate them!

Made my first real cut today with my shop made cold saw. The piece was a little too big to cut all the way through, 2"x5.5", so I had to finish with a sawzall. Anyway, did a fine job as far as it would go.

Nice vise, for a shop made cold saw :biggrin:

I got some more done on the sander.

Got my new Phase II QCTP and needed some way of keeping the tool holders off the bench. Being a better woodworker than metalworker I made a quick prototype from a scrap of walnut. I think this will work until I get more tool holders and need a longer rack.
