Just getting in to brazing to make scale parts and possibly a tuber.

What surface do you use to braze on and with that, what do you use to hold the small parts in place while you braze.

Seems stupid but I am used to clamping pieces to a big metal table that are a lot larger, and I know you guys always have lots of good ideas on things like this. Thanks.

A buddy of mine picked me up a scrap piece of steel about 1/4" thick and about 1' square. As for holding it I ordered some magnets from harborfreight.com. just type in magnets and it will pull them up. I think they are made for welding but they are kinda in the shape of a triangle

I use a piece of alum. 1/8" thick x 6" wide x 3' long and welding magnets. The brazing doesn't stick to alum. I have a bunch of small triangle shaped pieces of alum. to go under the parts I'm working with to hold them up off the large piece of alum., this just makes heating up the tube faster.

I have a 12"x18" 1/16" steel sheet I got from homedepot riveted to a piece of plywood that I use as my brazing/welding tray and mini-magnets from weldingsupply.com

I use firebrick.

May seem odd, but I use a scrap piece of 1 inch thick hardboard built up into a small table. It doesn't resist heat at all, since it's wood, but it makes sure that I'm keeping the heat on the parts I'm brazing, and off of the table, which is much better in the end. I just keep some water nearby, but for all the frames I've made, I've never burned down my house yet

As for holding parts, I use a variety of sizes of welding magnets for large parts. For very small parts, such as nuts, I use needle nose pliers. The procedure for how to do this has been described elsewhere in this section (you'll need to search for it).

what is firebrick? I also use small magnets and two large magnets that are connected.

Firebricks are the masonry liner bricks used in wood burning fireplace building to line the back of the firebox where the main heat source (logs) is burning. Very heat resistant and can be bought in varying sizes and pretty flat too. Good idea for a brazing surface.

I went cheap I guess. Found a couple pieces of aluminum framing a while back and that's what I use. They're about 2 feet long each and I usually can get away with using one in order to not burn up my wood workbench.

As far as holding pieces, I just get creative. I've used vise grips(small ones, needle nose and regular), my bench vise, wire, tape(don't get too close with the torch, burnt tape is messy) and whatever else I have laying around that fits the purpose.
