For paint to last, clean all the paint with chemical paint stripper, than wash very well, and remove all the rust and corrosion with acid, or if you can a good sand blast machine. Apply a good epoxy primer, then scotch brite to scratch the primer for apply a good finish color (Acrylic). It will...

First I line up everything then I join everything with little points of TIG welding, the process I normally use for the welding, finally weld everything, normally with the structure in the jig. What happens is that my work table have a distortion due to be MDF, and with the humidity is a little...

Approximately that, is 30 mm, measures in inches are a little bit difficult to find here in Portugal, is less 1.75 mm from 1 1/4.

The front suspension block is in place, and the jig for the A-Arms is in construction. At this point I can see that the frame have a :censored: 1 or 2 mm torsion :mad2:, and is on a hard surface clamped to distortion, I think that tomorrow it will be on the place. Thanks r97, I will try to make...

Not so heavy, the bolt in diameter is 3/8, and the recommended from the plan is 5/8, in this part is a little bit lighter. The black bushing is auto lubricated nylon, very strong and very light, the steel bushing, similar to th plan in measures. I think is a little bit lighter than what the...

These are the bushings that I'm going to use on the A-Arms. The bolt is typical aviation AN bolt. :thumbsup:

Stamos 200A AC/DC, works very well, rarely use MMA, but TIG almost every day, steel, stainless steel, and aluminum.

Today spent my time on the Mainframe that is almost complete. This is what the plans say, during this week, I try to made the modifications that I have planned. First I have finish all the weldings. :thumbsup: The lower frame is a little bit rusty, Last week rains a lot, and humidity is high...

So, my Lower Mainframe is fully welded and ready to join the upper frame. Waiting for the hinges between the Mainframe and Sub-Frame, that I have designed. :thumbsup:

Very nice work.

Nice, the only advise that I can give is to control the speed, is clear that some times you go fast and some times to slow on the same weld. Use a plate with 5 or more mm, and fill with weld all along of the plate, and you will see that you should start to control speed.

Could someone in the forum give me inner dimension of the brackets that are used on the arachnid plan? It's only to have an idea, I'm going to made those for the kind of hinges that I'm planning to do. And if is not ask to much the dimensions of the weldments for the rear axle. Thanks.

Start with Mainframe, I have made a kind of jig in my work table. Then I give it some points of weld, turn it around to confirm that the frame is equal on both sides, more point of weld. At last a good weld on top and bottom. As you can see on the video below, the frame is symmetric...

I'm starting the Arachnid, and stretched to plus 220 mm on the Mainframe, considering to put them wider plus 200 mm. I work in aeronautical industry, and finish the day is work place clean and all the tools stored on the place, is an habit. :D

It's time for a overhaul to the engine, nothing better to really know how your engine is inside, but first, are you sure that the nut is inside? It seems that the nut is alive and hiding from you.
