The Multiplaz 3500 is a new kind of plasma machine from Russia that has some interesting potential for knifemakers. What is unique about the machine is that it welds, cuts, brazes and heats using only electricity, water and sometimes alcohol (metho). There are no other gasses used, saving a significant amount in consumables and running costs. It is light portable and versatile in its application. It can replace three separate machines in the workshop - oxy/acetalyene torch, welder and plasma cutter.
This is the first in a series of articles reviewing the Multiplaz 3500 - Unboxing.
Opening the box
Mine been opened by the courier and then resealed (everything was intact). What surprised me on opening the box that there was minimal packing and the unit was neatly packed in its carry bag. The bag is a robust design, with pockets for everything and easy to carry. The full bag weighs in at only 9kg, making it easy to move around.
The Multiplaz 3500 comes with a full range of accessories, plus some generous spares to keep you going. There are no additional bits to buy, it is complete, something of a rarity with tools these days. The pieces seem well through through and well made. There is one odd looking tool that can take apart every part of the torch.

Here's a tutorial on how to make a propane gas forge out of bits and pieces. It's not too hard, it just takes some time and some scrap steel. There are lots of ways to make a forge, this one suits my needs. It can be made with a single opening or a double opening for long pieces. The parts can be improvised, but note the bigger the forge cavity - the harder it will be to heat.
Feel free to use and develop the ideas. We accept no responsibility on the use of forges you make with this information. Please be careful as working with gas can be dangerous and possibly fatal. I accept no liability for any injury which may occur by you following these pictures. They are intended for you information.
Some thoughts on using the LPG (propane) forge, is it not meant to be a definitive guide and it is to be used at your own risk.
Mark II of our knife vice is much stronger and easier to adjust, thanks to some nice knurls with M10 threads. Simple to make - a strong piece of angle iron, a scrap of 10mm flat bar, 200mm of rectangular section, an M10 nut (or what ever suits your bolt), a washer, some scrap 3mm MDF and two M10 bolts with a knurled end. Drill a 10mm hole in the back of the angle iron and in the front of the rectangular section. Drill an 8.5mm hole in the scrap of 10mm and tap an M10 thread, weld the nut onto the rectangular section and then the 10mm piece on the back. Clean up, paint and assemble.
Unscrew the back to move, and do up to lock. Simple.
