Blue styrofoam insulation material was used to make the molds. For the fenders approximate shapes were cut and glued side by side from 50mm thick sheets to form the shape. After that the mold was followed with rough sanding and covering the mold with aluminium foil tape. Polyester resin does...

So here are few build pictures as promised. In the first one the rear frame is being jigged for welding. The sheet parts shown were plasma cut and bend by students of my school. The pump plate and motor plate shown in the picture were also bolted in before welding to align the parts...

Thanks. I will make sure to post some build pictures tomorrow. The machine sure helps when it does snow properly. The machine is capable of moving around 400 kg (880lb) in one pass. Its rather tiresome to move even that amount of snow after a day in school or at work:D Theoretically it can...

This might not be the most appropriate forum for my build but I like it here so :fan: So it is a small wheel loader made as a school project during the past three years. The machine has a hydraulic drive train. 27 hp gasoline V2 engine is driving a variable displacement piston pump for drive...

Search "parker o-ring handbook" from google. The pdf has pretty much all there is to know about o-rings.

Just about flat cams. Seems like the designer of this engine didnt hesitate with flats. Engine is from a T-72 tank. [/URL][/IMG] Henri

Ok thanks. So pretty much everything involved with any normal welding method seem to count in this also. I am fond to this method as it is so accurate, but I guess TIG will be just as accurate if a good fixture is made.

I will try that if I make further experiments;) I was led to doing this how I do by some videos on friction welding where I didnt see anything related to inert gas. Do you know if inert gas is needed on mild steel while friction welding? Also I believe that some of that brittleness was caused...

First complete valve made with this technique. Again it took three trys to get a holding joint. The other ones would weld but they cracked while bending. This one could take some visible bending of the stem but I am not sure how much it could take. The steel build up around the weld was easy to...

Hi I did some testing to figure out if friction welding stainless steel valve stems would be possible at home. First I tried to do this with some scrap materials on lathe but I could not get a good joints. Also the tailstock was not really up to the task. For the next try I bough some 4mm...

Unbelievable work! Can I ask how you machined the valve stems and to what kind of tolerances did you bind yourself in to? I tried to do similar valves on lathe but I had taper of perhaps 0.04mm over the length of 40mm stem.

Ok... I placed my order just before your reply. I bought all the tools I mentioned at the last post. v block and slitting saw sure would be useful but they must wait for now. I have dial indicator to set up everything. Seems like test indicator would be more useful in many situations. Now week...

Again thanks for all the help you have given=) So... Situation is this. Arceurotrade does seem to want credit card so I must turn to my father:wall: We planned that he could order the mill tomorrow. Sx2 with mt3 should be my choice. I have few more question for you. What vise to get from...

Hey all I think I must introduce my self you guys. So I am a young chap from Finland. I have been tooling up for a year now to properly start model engineering. Currently I own a sieg c3 and a mill is next to come in. I am currently doing a internship working for worlds second largest...

Hey Thanks for all the answers this far. Seems like the SX2 would be the choice from those machines. For tooling HSS end mills 4,6,8,10mm (also rounding bits) Radial Milling Vices Tilting vice Boring head and arbor¨ edge finder R8 collet set Then rotary table later on. I...

Hey I have been lurking around in the dark corners of this forums learning from the masters. I bought a mini lathe about one year ago. I have done quit a bit of parts for my projects with it. But I run into the "need a mill" problem bit too often so its about time to get one. There...
