Handlaying Straight Track

Very nice work.

One thought on the aluminium acting as a heat sink and possible cold solder joints.

A resistance soldering rig would solve that problem.

Pre-tin the tie. A little dab of Flux at the joint and a quick zap with the resistance rig.

Thanks TinGoat.

I have a resistance soldering rig. I've already been thinking of a tool that I can make to use for soldering the rail. It's a DYI rig. I use a microwave transformer. It put's out over 400amps at the terminals. If the group is interested I can write up a post on constructing one. And before anybody get's excited about the idea of using a microwave transformer, it doesn't output high voltage. The transformer gets modified. So, anybody interested?

I used a soldering gun. Worked pretty good. I actually had to modify the jig so the rails would not sit on the aluminum jig themselves, but only on the ties. Still the sides touch the jig somewhat and suck some of the heat away.

I did some wood ties in the jig and will post pictures later tonight or tomorrow.

Thanks Alex. It's taking a little longer than expected. Crashed the machine last night. Jammed the engraving tool into one of the production jigs. Put a nice hole in the jig plus it totally destroyed the carbide engraver. I'll take some pictures.

Hang in there guys. Minor set back.

Funny you should mention a microwave transformer.

They were throwing one out at work yesterday.

I saw a YouTube video a while ago that used a modified microwave transformer to build an arch welder.

Save yourself the trouble of writing something up.

A local Canadian, Paul James, wrote up how to build a variable power Resistance Soldering rig.

I've got a pdf that I can post but you'll have to wait until Monday 'cause it's on my work computer.

Here's what happens when you're not paying attention to your work. I clicked on the wrong icon on the computer. Instead of the "Z" axis going up 1" it went down 1" from a height of .5". So it tried to drilled through the jig before I could stop it. Just damaged the cutter and have a nice hole in the jig.

Image

On with the show.

I'm using Clover House's PC ties for the next demonstration. The jig has a slot milled in on the upper right hand corner for cutting the PC ties to length. You'll need to file the sides down a bit for a loose fit. I take a file and run it diagonally across the full length of the tie strip. This gets rid of some of the burrs that keep the tie from fitting in the slot.

Image

Place the PC full length tie strip in the slot and cut off with a pair of side cutters. I use the Xruon Rail Nippers. Be careful the cut off piece can go flying.

Image

Notice that there's the possibility of the tie being to long. File or nip off with cutters.

Image

Fill the jig up with the 5 tie spacing or skip to a 10 tie spacing. I think for straight trck making every 10th tie a PC tie will work fine. Experiment to see what works for you.

Image

Image

Here I've got a roll of ties ready to be put down. The rail with the PC ties soldered to them has both a 5 PC and 10 PC tie spcaing. The first foot or so is the 5 spacing the rest is 10.

Image

Image

Rolling out the ties.

Image

I didn't glue anything down yet. I wanted to see how this would all work. Glad I didn't glue it.

Image

Image

Toward he end of the three foot section of track the ties didn't line up. My conclusion is that the tape stretches, plus you shouldn't use sections of tape but one full length. Even then the section should only be as long as the jig, 8".

Image

I'll post a bit later on using shorter sections of the tie spacing jig.

Using just short sections, the length of the tie jig, and a 10 tie spacing seems to work pretty good.

Image

Image

Image

And at the end of the three foot rail section. Using the short sections seems to work out better.

Image

That's it for now. The machine is happily running it's job as I type this.

Woohoo! Awesomeness. I'll take the jig with the hole - no need to discard it.

Drill it on thru and use it to hang the fixture on the wall when not in use........DaveB
