not much happening on the forum in the past week so I will give a long over due update
little going on here. I finished the columns today broke another drill bit (getting the hang of these small ones though) when I drilled through the silver soldered screw and reached the gap below it. I removed the bit by heating some of the pickle solution and it came out great with very little effect on the finished part.
Working on the upper/lower bolsters now along with the arch bars and I still have one more axle to finish and all the journal boxes

today I finished the upper and lower bolsters to the proper thickness and drilled the center through hole in the upper bolsters
I am thinking that for accurate layout I will use the center hole and a center finder and mark off from the center. I dont know if the is the best way but it seems like a good way to keep everything measured from the center like the book specifies.
My other though was to but into a plate and measure in but errors could creep in due to slight variations in the lengths of each bar.

I am thinking that for accurate layout I will use the center hole... My other thought was to butt into a plate and measure in but errors could creep in due to slight variations in the lengths of each bar. You may have already done this by now since the message is a few days old but... For accuracy your first thought is probably best. Go from center out. Not knowing what you have for tool set but you would find a pin that fits the hole you drilled. You want it snuggish; a good solid sliding fit--should not have to press or hammer in--but you don't want wobble either. Measure from one side of the pin to the end of the bolster and either subtract or add half of the pin diameter (depending on whether you're measuring from side of the pin nearest or away from the end of the bolster you're marking). I would put it on the surface plate and stand it up against an angle plate and use a square (or piece of straight metal clamped to the angle plate vertically) then use the height gauge or similar to measure and mark one end at a time.

I have not done it yet, been away from work and thus my tools. I was planning on using a center finder to locate the center and measure out for each of the holes/cuts.

Try Micro Fasteners. They have #0, #1, #3 brass fasteners at very competitive prices. 1-64 is hard to find. I have been using 1-72 on my A3.

its been going a bit slow lately, I have been researching and buying bits to convert my x3 to a cnc. I have finished 2 of the 3 archbars. I have to remake the 1/16" bars because I had cut them too short initially.
